联合收割机割取种植谷秆，对割取谷秆进行脱粒分选处理，将获得的谷粒(分选处理物)输送到谷粒箱并存储。若割取谷秆不被适当地脱粒，则将在谷粒中产生损伤。另外，若不适当地进行分选，则在分选处理物中混入谷粒以外的夹杂物等异物。其结果，不能取得适当品质的谷粒。The combine harvester harvests the planting grain stalks, performs threshing and sorting on the harvested grain stalks, and transports the obtained grains (sorted products) to a grain box for storage. If harvested straw is not properly threshed, damage will develop in the grain. In addition, if the classification is performed improperly, foreign substances such as inclusions other than grains will be mixed in the sorting processed product. As a result, grains of appropriate quality cannot be obtained.

因此，例如在专利文献1所记载的联合收割机中，在谷粒箱内部具备暂时存储部，具备对存储于该暂时存储部的分选处理物进行拍摄的相机，基于分析拍摄图像而获得的谷粒的分选精度(异物的混入等)，调整脱粒装置等的各种设定。Therefore, for example, in the combine harvester described inPatent Document 1, a temporary storage unit is provided inside the grain tank, and a camera for photographing the sorting and processing objects stored in the temporary storage unit is provided, and the data obtained based on the analysis of the captured image is provided.

Take pictures of sorting objects in the department, adjust various settings of the threshing device, etc. Therefore, for example, when at least a part of the threshing processed product threshed by the threshing device stays in the threshing device and there is a threshing processed product not transported to the temporary storage unit, the above-mentioned setting cannot be appropriately performed.

因此，要求能够适当地测定脱粒处理物的量的联合收割机。Therefore, the combine harvester which can measure the quantity of a threshing process material suitably is requested|required.

2－2.课题〔2〕2－2. Subject [2]

另外，在专利文献1所记载的联合收割机中，将通过输送装置输送到谷粒箱并投掷到存储部内的分选处理物存储于在谷粒箱的后部(离开投掷部的位置)支承的暂时存储部，因此在暂时存储部积存分选处理物花费时间，确认分选处理物的分选精度、品质的定时延迟的可能性较高。其结果，例如有进行反映了分析结果的机体控制花费时间、控制的反应延迟的情况。In addition, in the combine harvester described inpatent document 1, the sorting process object conveyed to the grain tank by the conveying device and thrown in the storage part is stored in the rear part (position separated from the throwing part) of the grain tank and supported. Therefore, it takes time to store the sorted objects in the temporary storage, and the timing for confirming the sorting accuracy and quality of the sorted objects is likely to be delayed. As a result, for example, it may take time to perform biological control reflecting the analysis results, and the control response may be delayed.

因此，要求能够适当地存储所分选的分选处理物的联合收割机。Therefore, the combine harvester which can store the sorted sorting process object suitably is requested|required.

根据这种构成，能够进一步减少向脱粒装置输送的作物的量。因而，能够使停留在脱粒装置的脱粒处理物的脱粒处理最优先。According to such a structure, the quantity of the crops conveyed to a threshing apparatus can be reduced further. Therefore, it is possible to prioritize the threshing process of the threshing processed product staying in the threshing apparatus.

另外，优选的是，具备报告部，该报告部在即使在所述漏下开度变大并且所述风量增大的情况下、所述比率也不变小时进行报告。In addition, it is preferable to include a reporting unit that reports that the ratio does not become smaller even when the leakage opening degree increases and the air volume increases.

根据这种构成，能够向周围明示二次处理物返还量相对于一次处理物回收量的比率变小。因而，操作人员能够进行规定的处置等来应对。According to such a configuration, it can be clearly shown to the surroundings that the ratio of the returned amount of the secondary treated matter to the recovered amount of the primary disposed matter is reduced. Therefore, the operator can take a predetermined measure or the like to deal with it.

The threshingdevice 1 , thegrain tank 12 and thegrain discharge device 14 .

割取部4具备耙拢作物的耙拢拨禾轮5、切断田地的作物的推子型的切断装置6、将割取的作物横向进给到送料器11的绞龙7。由割取部4割取的作物由送料器11输送到脱粒装置1，由脱粒装置1进行脱粒分选处理。由脱粒装置1进行了脱粒分选处理的分选处理物存储于谷粒箱12，适当地由谷粒排出装置14排出到机外。Theharvesting unit 4 includes a raking reel 5 for raking crops, a clipper-type cutting device 6 for cutting crops in the field, and anauger 7 for laterally feeding the harvested crops to thefeeder 11 . The crops harvested by theharvesting unit 4 are transported to the threshingdevice 1 by thefeeder 11 , and the threshingdevice 1 performs threshing and sorting treatment. The sorting processed product subjected to the threshing and sorting process by the threshingapparatus 1 is stored in thegrain tank 12, and is discharged|emitted to the outside by thegrain discharge apparatus 14 suitably.

在割取部4的右后方，以与送料器11横向排列的状态配备有驾驶部9。驾驶部9被驾驶舱10覆盖。在驾驶部9的下方配备有发动机舱ER，在发动机舱ER中收容有发动机E，虽然未特别图示，还收容有冷却风扇、散热器等。发动机E的动力通过未图示的动力传递机构传递到行驶装置3、割取部4、脱粒装置1等作业装置。On the rear right side of theharvesting unit 4 , adriving unit 9 is provided in a state aligned with thefeeder 11 in the lateral direction. Thecockpit 9 is covered by acockpit 10 . An engine compartment ER is provided below thecab 9, and the engine E is accommodated in the engine compartment ER, and although not shown in particular, a cooling fan, a radiator, and the like are accommodated therein. The motive power of the engine E is transmitted to working devices such as the travelingdevice 3 , theharvesting unit 4 , and the threshingdevice 1 through a power transmission mechanism not shown.

接下来，使用图3所示的脱粒装置1的纵剖左侧视图，对脱粒装置1的构成进行说明。脱粒装置1设于机体框架2，具备利用脱粒筒22对作物进行脱粒的脱粒部41与对脱粒处理物接着摆动分选处理的分选部42。脱粒部41配置于脱粒装置1中的上部区域，在脱粒部41的下方设置有筛网23，分选部42设于筛网23的下方。分选部42将从筛网23漏下的脱粒处理物分选为包含应回收的谷粒的分选处理物和废秸秆等排出物。Next, the structure of the threshingapparatus 1 is demonstrated using the longitudinal sectional left side view of the threshingapparatus 1 shown in FIG. The threshingapparatus 1 is provided in thebody frame 2, and is equipped with the threshingpart 41 which threshed crops with the threshingcylinder 22, and the sortingpart 42 which followed the rocking sorting process to the threshing processed object. The threshingpart 41 is arrange|positioned in the upper area in the threshingapparatus 1, thesieve 23 is provided in the lower part of the threshingpart 41, and the sortingpart 42 is provided in the lower part of thesieve 23. The sortingpart 42 sorts the threshing process material which leaked from thesieve 23 into the sorting process material containing the grain which should collect|recovery, waste straw, etc. discharge|emissions.

脱粒部41具备由脱粒装置1的左右的侧壁、顶板53以及筛网23包围的脱粒室21。在脱粒室21配备有通过旋转对作物进行脱粒处理的脱粒筒22与多个送尘阀53a。由送料器11输送的作物投入到脱粒室21，由脱粒筒22进行脱粒处理。通过脱粒筒22连动旋转的作物在送尘阀53a的输送作用下朝向后方移送。The threshingpart 41 is equipped with the threshingchamber 21 surrounded by the left and right side walls of the threshingapparatus 1, thetop plate 53, and thescreen 23. The threshingchamber 21 is equipped with the threshingcylinder 22 which rotates and threshing crops, and severaldust delivery valves 53a. The crops conveyed by thefeeder 11 are put into the threshingchamber 21 and are threshed by the threshingcylinder 22 . The crops rotated in conjunction with the threshingcylinder 22 are transferred toward the rear under the conveying action of thedust sending valve 53a.

送尘阀53a为板状，沿前后方向以规定的间隔设置于顶板53的内表面(下表面)。送尘阀53a以在俯视时相对于旋转轴心X倾斜的姿态设置。因此，各个送尘阀53a作用使在脱粒室21中与脱粒筒22一同旋转的割取谷秆向后侧移动的力。另外，送尘阀53a能够调整相对于旋转轴心X的倾斜角度。在脱粒筒22内将作物送至后方的速度根据送尘阀53a的倾斜角度决定。另外，作物被脱粒的脱粒效率也被作物在脱粒筒22内输送的速度影响。其结果，作物被脱粒的处理能力能够使用各种手段来调整，但能够将变更送尘阀53a的倾斜角度作为一个手段来调整。虽然未特别图示，但配备有能够变更控制送尘阀53a的倾斜姿态的送尘阀控制机构，能够自动地变更送尘阀53a的倾斜角度。Thedust sending valve 53a is plate-shaped, and is provided on the inner surface (lower surface) of thetop plate 53 at predetermined intervals along the front-rear direction. Thedust sending valve 53a is provided in the attitude inclined with respect to the rotation axis X in planar view. Therefore, eachdust sending valve 53a acts as the force which moves the harvested grain stalk which rotates together with thebarrel 22 in the threshingchamber 21 to the rear side. Moreover, the inclination angle with respect to the rotation axis X of thedust sending valve 53a can be adjusted. The speed at which crops are sent to the rear in the threshingcylinder 22 is determined by the inclination angle of thedust delivery valve 53a. In addition, the threshing efficiency with which the crop is threshed is also affected by the speed at which the crop is conveyed within the threshingdrum 22 . As a result, the threshing processing capacity of the crops can be adjusted by various means, but it can be adjusted by changing the inclination angle of thedust sending valve 53a as one means. Although not shown in particular, a dust valve control mechanism capable of changing and controlling the inclination attitude of thedust valve 53a is provided, and the inclination angle of thedust valve 53a can be automatically changed.

脱粒装置1具备一次处理物回收部26、二次处理物回收部27以及二次处理物返还装置32。分选部42包括具有筛分壳体33的摆动分选装置24与风选机19。The threshingapparatus 1 is provided with the primary processingobject recovery part 26, the secondary processingobject recovery part 27, and the secondary processingobject return apparatus 32. The sortingunit 42 includes aswing sorting device 24 having a screeninghousing 33 and awinnowing machine 19 .

风选机19设于分选部42的前部区域的下部区域，从摆动分选装置24的前侧朝向后方沿处理物的输送方向产生分选风。分选风具有将比重相对较轻的废秸秆等朝向筛分壳体33的后侧送出的作用。另外，在摆动分选装置24中，筛分壳体33利用摆动驱动机构43摆动，使得筛分壳体33的内部的脱粒处理物一边被向后方移送一边进行摆动分选处理。出于这种理由，在以下的说明中，在摆动分选装置24中，处理物的输送方向的上游侧被称作前端或者前侧，下游侧被称作后端或者后侧。另外，关于风选机19的分选风，能够变更强度(风量，风速)。若增强分选风，则容易向后方送出脱粒处理物，分选速度变高。相反，若减弱分选风，则脱粒处理物较长地停留在筛分壳体33内，分选精度变高。因此，风选机19的分选风通过变更强度，能够调整摆动分选装置24的分选效率(分选精度、分选速度)。虽然未特别图示，但配备有能够变更控制风选机19的分选风的强度的风选机控制机构，能够自动地变更风选机19的分选风的强度。Thewind separator 19 is provided in the lower region of the front region of the sortingunit 42, and generates sorting wind from the front side of theswing sorting device 24 toward the rear along the conveyance direction of the processed objects. The sorting wind has the effect of sending the waste straw and the like with relatively light specific gravity toward the rear side of the screeninghousing 33 . In addition, in theswing sorting device 24 , thescreening case 33 is swung by theswing drive mechanism 43 , so that the threshing processed material inside the sortingcase 33 is transported backward while undergoing a swing sorting process. For this reason, in the following description, in theswing sorting device 24 , the upstream side in the conveyance direction of the processed object is referred to as the front end or the front side, and the downstream side is referred to as the rear end or the rear side. In addition, regarding the sorting air of the winnowingmachine 19, the strength (air volume, wind speed) can be changed. If the sorting wind is strengthened, the threshing processed product will be easily sent to the rear, and the sorting speed will be increased. Conversely, if the sorting wind is weakened, the threshing processed material stays in thescreening case 33 for a long time, and the sorting accuracy becomes high. Therefore, by changing the intensity of the sorting wind of the winnowingmachine 19, the sorting efficiency (separation accuracy, sorting speed) of theswing sorter 24 can be adjusted. Although not shown in particular, a wind separator control mechanism capable of changing and controlling the intensity of the sorting wind of thewind separator 19 is provided, and the intensity of the sorting wind of thewind separator 19 can be automatically changed.

在筛分壳体33的前半部分配备有第一谷壳筛38，在筛分壳体33的后半部分配备有第二谷壳筛39。由于是一般的构成，所以不特别说明，但在筛分壳体33中，除了第一谷壳筛38等以外，还配备有谷粒抖动板、谷粒筛40。在筛网23中漏下的脱粒处理物向第一谷壳筛38、第二谷壳筛39落下。脱粒处理物的绝大多数从筛网23相对于包含第一谷壳筛38的筛分壳体33的前半部分漏下，由筛分壳体33的前半部分粗分选以及精分选。一部分的脱粒处理物从筛网23相对于第二谷壳筛39漏下，或在第一谷壳筛38中不漏下地移送到第二谷壳筛39而在第二谷壳筛39中漏下并被分选。Afirst chaff sieve 38 is provided in the front half of the sievinghousing 33 , and asecond chaff sieve 39 is provided in the rear half of the screeninghousing 33 . Since it is a general structure, although it does not demonstrate in particular, in thesifting case 33, the1st chaff sieve 38 grade|etc., the grain shaking plate and the grain sieve 40 are equipped. The threshed processed material dropped on thesieve 23 falls to the1st chaff sieve 38 and the2nd chaff sieve 39 . Most of the threshing processed material leaks down from thescreen 23 with respect to the front half of the sievinghousing 33 including thefirst chaff sieve 38 , and is roughly sorted and finely sorted by the first half of the sievinghousing 33 . A part of the threshed processed product is transferred from thesieve 23 to thesecond chaff sieve 39 with respect to thesecond chaff sieve 39 , or is transferred to thesecond chaff sieve 39 without falling through thefirst chaff sieve 38 and then leaked in thesecond chaff sieve 39 . down and be sorted.

在第一谷壳筛38的下方配备有上述谷粒筛40。即，摆动分选装置24具备设于第一谷壳筛38的下方的谷粒筛40。谷粒筛40由冲孔金属、网体等多孔部件构成，接住从第一谷壳筛38漏下的脱粒处理物并进行漏下分选。Below the1st chaff sieve 38, the said grain sieve 40 is arrange|positioned. That is, the swingingsorting device 24 is provided with the grain sieve 40 provided below the1st chaff sieve 38 . The grain sieve 40 is comprised by porous members, such as a punched metal and a net body, and catches the threshing process material which leaked from the1st chaff sieve 38, and performs drop-off sorting.

在筛分壳体33的前半部分的下方配备有螺旋式的一次处理物回收部26，在筛分壳体33的后半部分的下方配备有螺旋式的二次处理物回收部27。由筛分壳体33的前半部分分选处理而漏下的一次处理物、即由分选部42分选的分选处理物中的一次处理物被一次处理物回收部26回收而朝向谷粒箱12的侧(机体左右方向右侧)输送。由筛分壳体33的后半部分(第二谷壳筛39)分选处理而漏下的二次处理物(一般来说分选处理精度较低，切割秸秆等的比率较高)、即分选处理物中的二次处理物被二次处理物回收部27回收。二次处理物相当于脱粒处理物中的中未作为分选处理物分选的脱粒处理物。由二次处理物回收部27回收的二次处理物被二次处理物返还装置32返还到分选部42的前部，被筛分壳体33再次分选。Below the front half of the screeninghousing 33 is provided a spiral primary treatedproduct recovery unit 26 , and below the rear half of the screeninghousing 33 is provided a spiral secondary processedproduct recovery unit 27 . The first-half part of the sorting process of thescreening case 33 and the primary processed products that have been missed, that is, the primary processed products among the sorted processed products sorted by the sortingunit 42 are collected by the primary processedproduct recovery unit 26 and directed toward the grains. The side of the box 12 (the right side in the left-right direction of the machine body) is conveyed. Secondary processed products (generally speaking, the accuracy of the sorting process is low, and the ratio of cut straw etc. is high), which is sorted by the second half of the screening case 33 (the second chaff sieve 39 ), that is, Secondary processed objects among the sorted processed objects are recovered by the secondary processedobject recovery unit 27 . The secondary processed material corresponds to the threshing processed material which was not sorted as the sorting processed material among the threshing processed material. The secondary processed objects recovered by the secondary processedobject recovery part 27 are returned to the front part of the sortingpart 42 by the secondary processedobject returning device 32 , and are sorted again by thescreening case 33 .

在第一谷壳筛38配备有沿脱粒处理物的移送(输送)方向(前后方向)排列设置的多个板状的谷壳刮板(chaff lip)。各谷壳刮板以越靠后端侧越朝向斜上方的倾斜姿态配置。谷壳刮板的倾斜角度为可变，倾斜角度越陡，相邻的谷壳刮板彼此的间隔越宽，脱粒处理物越容易漏下。即，构成为能够通过变更多个谷壳刮板的姿态来变更漏下开度。因此，通过调整谷壳刮板的倾斜角度，能够调整摆动分选装置24的分选效率(分选精度、分选速度)。配备有够变更控制谷壳刮板的倾斜姿态的刮板控制机构，能够自动地变更谷壳刮板的倾斜角度。Thefirst chaff sieve 38 is provided with a plurality of plate-shaped chaff scrapers (chaff lips) arranged in a row along the transfer (transportation) direction (front-rear direction) of the threshing processed material. Each chaff scraper is arrange|positioned in the inclination attitude|position which becomes obliquely upward toward the rear end side. The inclination angle of the chaff scraper is variable, and the steeper the inclination angle, the wider the interval between adjacent chaff scrapers, and the easier it is for the threshing process to leak. That is, it is comprised so that the leak-off opening degree can be changed by changing the posture of several chaff scrapers. Therefore, by adjusting the inclination angle of the chaff scraper, the separation efficiency (separation accuracy, separation speed) of theswing separation device 24 can be adjusted. Equipped with a scraper control mechanism capable of changing and controlling the inclination attitude of the chaff scraper, the inclination angle of the chaff scraper can be automatically changed.

第二谷壳筛39也是与第一谷壳筛38相同的构成。还具备能够变更控制第二谷壳筛39的谷壳刮板的倾斜姿态的角度控制机构，能够自动地变更谷壳刮板的倾斜角度。Thesecond chaff sieve 39 is also the same structure as thefirst chaff sieve 38 . Furthermore, it is equipped with the angle control mechanism which can change and control the inclination attitude|position of the chaff scraper of the2nd chaff sieve 39, and can change the inclination angle of a chaff scraper automatically.

Thegrain lifting device 29 is arrange|positioned between the threshingdevice 1 and thegrain tank 12, and is erected in the posture along an up-down direction.Yang valley device 29 is made up of the conveyor of bucket type. The sorted processed objects lifted by thevalley lifting device 29 are handed over to the transversefeed conveying device 30 at the upper end of thevalley lifting device 29 . The horizontalfeed conveyance apparatus 30 is comprised in the spiral type, and it sinks in the inside of thegrain tank 12 from the wall part of the front part left side of thegrain tank 12. 30 A of grain discharge apparatuses are provided in the end part of the tank inside side of theinfeed conveyance apparatus 30. As shown in FIG. 30 A of grain discharge apparatuses are provided with the plate-shaped dischargerotary body 30B, and rotate integrally with a screw part. The sorting process object is laterally conveyed by theinfeed conveyance apparatus 30, and is finally thrown into thegrain tank 12 by 30 A of grain discharge apparatuses.

在扬谷装置29中，如图4以及图5所示，在卷绕于驱动链轮29A与从动链轮29B的环形转动链29C的外周侧以一定间隔安装有多个铲斗31。扬谷装置29具备供收纳有分选处理物的铲斗31上升的输送路径29D和供将分选处理物排出到横向进给输送装置30之后的铲斗31下降的返回路径29E。输送路径29D与返回路径29E以输送路径29D成为后侧的方式沿谷粒箱12的左侧壁12b排列地配置。In thegrain lifting device 29, as shown in FIG. 4 and FIG. 5, a plurality ofbuckets 31 are attached at regular intervals on the outer peripheral side of theendless rotation chain 29C wound around the drivingsprocket 29A and the drivensprocket 29B. Thegrain lifting device 29 includes aconveyance path 29D through which thebucket 31 storing the sorted processed object rises, and areturn path 29E through which thebucket 31 descends after the sorted processed object is discharged to the lateralfeed conveyance device 30 . Theconveyance path 29D and returnpath 29E are arrange|positioned along theleft side wall 12b of thegrain tank 12 so thatconveyance path 29D may become a rear side.

一次处理物传感器60测定一次处理物的回收量作为一次处理物回收量(参照图10)。一次处理物传感器60配置为在分选处理物从一次处理物回收部26输送至谷粒箱12的输送路径中的任意位置、具体而言是从一次处理物回收部26到分选处理物投掷到谷粒箱12的投掷口30C的任意位置测定分选处理物的量。一次处理物传感器60例如可以构成为使用物理接触式的传感器来检测分选处理物的量。或者，也可以使用将一次处理物的回收量与表示田地的地图的地图信息建立关联而生成的地图传感器的结果，例如也可以在从一次处理物回收部26到投掷口30C的任意位置设置相机，基于用该相机拍摄到一次处理物回收部26中的一次处理物的拍摄图像、拍到从脱粒装置1的脱粒筒22向下方落下的谷粒的拍摄图像、拍到从脱粒装置1的筛分壳体33向下方落下的谷粒的拍摄图像、拍到投入到谷粒箱12的谷粒的拍摄图像、拍到由铲斗31输送的谷粒的拍摄图像等，测定(推断)一次处理物的回收量。另外，也可以利用一次处理物回收部26的螺杆的负载(转矩等)测定(推断)一次处理物的回收量。The primary processedproduct sensor 60 measures the recovered amount of the primary processed product as the recovered primary processed product (see FIG. 10 ). The primaryprocessing object sensor 60 is arranged at any position in the conveyance path from the primary processingobject recovery part 26 to thegrain tank 12, specifically, from the primary processingobject recovery part 26 to the sorting processing object throwing. The quantity of the sorting process object is measured to the arbitrary position of 30 C of throwing openings of thegrain tank 12. The primary processedobject sensor 60 may be configured to detect the amount of the sorted processed object using, for example, a physical contact sensor. Alternatively, the result of a map sensor generated by associating the amount of recovered primary disposal with map information representing a field map may be used, and for example, a camera may be installed at an arbitrary position from the primarydisposal collection unit 26 to the throwingport 30C. Based on the captured image of the primary processed product in the primary processedproduct recovery unit 26 captured by the camera, the captured image of the grain falling downward from the threshingcylinder 22 of the threshingdevice 1, and the captured image of the grain from the threshingdevice 1 through the sieve The captured image of the grains dropped downward by the sub-housing 33, the captured image of the grains thrown into thegrain tank 12, the captured image of the grains conveyed by thebucket 31, etc., are measured (inferred) once and processed recycling amount. In addition, the recovered amount of the primary processed product may be measured (estimated) using the load (torque, etc.) of the screw of the primary processedproduct recovery unit 26 .

如上述那样，二次处理物被二次处理物返还装置32返还到作为摆动分选装置24的前部的上游侧。具体而言，二次处理物返还装置32的二次处理物排出口32A设于圆弧状的筛网23中的径向外侧的位置(筛网23的侧方，并且是二次处理物不通过筛网23的位置)，在该位置排出二次处理物。在脱粒装置1配备有测定如此返还的二次处理物的返还量作为二次处理物返还量的二次处理物传感器70。图6－图9中示出了这种二次处理物排出口32A的配置方式。As mentioned above, the secondary processed object is returned by the secondary processedobject returning apparatus 32 to the upstream side which is the front part of theswing sorting apparatus 24. As shown in FIG. Specifically, the secondary processedproduct discharge port 32A of the secondary processedproduct returning device 32 is located at a radially outer position in the arc-shaped screen cloth 23 (the side of thescreen cloth 23, and the secondary processed product does not The position passing through the screen 23) at which the secondary processed product is discharged. The threshingapparatus 1 is equipped with the secondaryprocessing object sensor 70 which measures the returning amount of the secondary processing object returned in this way as a secondary processing object returning amount. 6 to 9 show the arrangement of such a secondary processedproduct discharge port 32A.

在本实施方式中，如图6所示，二次处理物排出口32A朝向筛网23侧设置。如图7以及图8所示，在二次处理物排出口32A的附近设置有与构成二次处理物返还装置32的螺杆一同旋转的旋转叶片32B，由二次处理物返还装置32输送的二次处理物通过形成于脱粒部41的侧壁50的插通孔而由旋转叶片32B从二次处理物排出口32A向径向外侧排放(如图8的虚线箭头所示那样排出)。In this embodiment, as shown in FIG. 6 , 32 A of secondary processed material discharge ports are provided facing thescreen 23 side. As shown in FIGS. 7 and 8 , arotary blade 32B that rotates together with the screw constituting the secondary processedobject return device 32 is provided near the secondary processedobject discharge port 32A, and the two materials conveyed by the secondary processedobject return device 32 The secondary processed material is discharged radially outward from the secondary processedmaterial discharge port 32A by therotating blade 32B through the insertion hole formed in theside wall 50 of the threshing part 41 (discharged as indicated by the dashed arrow in FIG. 8 ).

在二次处理物排出口32A设置有将排放的二次处理物朝向摆动分选装置24的处理物移送方向上游侧引导的引导部32C。引导部32C由呈具有与二次处理物排出口32A对置的内周面的筒状的一部分的形状构成。换言之，成为将带板弯曲成圆弧状的形状。通过这种引导部32C的内周面，限制由旋转叶片32B排放的二次处理物的排出方向。Aguide portion 32C that guides the discharged secondary processed product toward the upstream side in the processed product transfer direction of theswing sorter 24 is provided at the secondary processed product discharge port 32A. 32 C of guide parts are comprised by the shape which has a cylindrical part which has the inner peripheral surface which opposes 32 A of secondary processed object discharge ports. In other words, the strip is bent into an arc shape. The discharge direction of the secondary processed material discharged by therotating blade 32B is regulated by the inner peripheral surface of theguide portion 32C.

如图7以及图8所示，二次处理物传感器70支承于脱粒部41中的侧壁50的内部侧部分。二次处理物传感器70构成为与由二次处理物返还装置32中的旋转叶片32B排放的二次处理物接触而测定返还的二次处理物的返还量。二次处理物传感器70具备：摆动臂72，位于由二次处理物返还装置32排放的二次处理物的排放延长线上，通过供排放的二次处理物接触而摆动；基于摆动臂72的摆动角测定返还量的测量部73；支承测量部73以及摆动臂72的支承框架74；以及覆盖二次处理物传感器70的上方的罩体75。As shown in FIGS. 7 and 8 , the secondary processedobject sensor 70 is supported by the inner side portion of theside wall 50 in the threshingunit 41 . The secondary processedproduct sensor 70 is configured to come into contact with the secondary processed product discharged from therotating blade 32B in the secondary processedproduct returning device 32 and measure the return amount of the returned secondary processed product. The secondary processedobject sensor 70 has: aswing arm 72, which is positioned on the discharge extension line of the secondary processed object discharged by the secondary processedobject return device 32, and swings by being contacted by the discharged secondary processed object; Measuringunit 73 for swing angle measurement return amount; supportingframe 74 for supporting measuringunit 73 andswing arm 72 ;

测量部73在壳体内装有电位计，利用螺栓紧固固定于支承框架74的内侧侧部位。关于测量部73，插通支承框架74而向外侧(侧壁50侧)突出地设置有旋转轴76，在旋转轴76上可一体转动地安装有摆动臂72。摆动臂72从旋转轴76朝向下方延伸，以位于由引导部32C引导二次处理物的引导路径内的状态配备。摆动臂72被支承为能够绕旋转轴76的轴芯摆动。The measuringpart 73 is equipped with a potentiometer in the case, and is fastened and fixed to the inner side part of thesupport frame 74 by bolts. Themeasurement unit 73 is provided with arotation shaft 76 protruding outward (side wall 50 side) through thesupport frame 74 , and aswing arm 72 is integrally rotatably attached to therotation shaft 76 . Theswing arm 72 extends downward from therotation shaft 76 and is provided in a state of being located in a guide path for guiding the secondary processed product by theguide portion 32C. Theswing arm 72 is supported so as to be able to swing around the axis of therotation shaft 76 .

罩体75构成为覆盖摆动臂72、测量部73以及支承框架74各自的上方。利用该罩体75，能够防止通过筛网23通漏下的脱粒处理物中的细小尘埃落在摆动臂72、测量部73上而阻碍测量动作。Thecover 75 is configured to cover the upper side of each of theswing arm 72 , themeasurement unit 73 , and thesupport frame 74 . Thiscover body 75 can prevent the fine dust in the threshing processed product leaking through thescreen 23 from falling on theswing arm 72 and themeasurement part 73 and hindering the measurement operation.

如图9所示，摆动臂72具有比旋转轴76向上方延伸突出的延伸突出部，跨越延伸突出部与弹簧支承部77地张设有线圈弹簧78。摆动臂72在线圈弹簧78的拉伸施力下，被施力为以接近二次处理物排出口32A的方式摆动。摆动臂72以上端部抵接于卡定部79，从而克服弹簧施力而以朝下待机姿态被保持位置。As shown in FIG. 9 , theswing arm 72 has an extending protrusion extending upward from therotation shaft 76 , and acoil spring 78 is stretched across the extending protrusion and thespring support portion 77 . Theswing arm 72 is urged to swing close to the secondary processedobject discharge port 32A by the tension bias of thecoil spring 78 . The upper end of theswing arm 72 abuts against the lockingportion 79 to be held in a downward standby posture against the biasing force of the spring.

若通过二次处理物排出口32A而由旋转叶片32B排放的二次处理物接触摆动臂72，则在其按压力下，摆动臂72克服线圈弹簧78的施力而向离开二次处理物排出口32A的方向摆动。此时的摆动角度被测量部73测量，基于该测量结果推算二次处理物的返还量。具体而言，优选的是将表示摆动角度与返还量的关系的地图、式子存储于测量部73，基于该地图、式子推算返还量。If the secondary processed product discharged by therotating blade 32B through the secondary processedproduct discharge port 32A contacts theswing arm 72, under its pressing force, theswing arm 72 overcomes the biasing force of thecoil spring 78 and moves away from the secondary processed product discharge. The direction ofoutlet 32A is swung. The swing angle at this time is measured by themeasurement part 73, and the return amount of a secondary processed object is estimated based on the measurement result. Specifically, it is preferable to store a map or an expression showing the relationship between the swing angle and the payout amount in themeasurement unit 73, and to estimate the payout amount based on the map or the equation.

图10是表示用于高精度地取得一次处理物传感器60的测定结果以及二次处理物传感器70的测定结果的控制所涉及的功能部的框图。另外，图11是本实施方式中的一次处理物回收量、二次处理物返还量与检测量的一个例子。如图10所示，一次处理物传感器60的测定结果以及二次处理物传感器70的测定结果被传递到测定结果取得部81。校正部82参照测定结果取得部81，用基于二次处理物传感器70的二次处理物返还量校正基于一次处理物传感器60的一次处理物回收量。FIG. 10 is a block diagram showing functional units related to control for obtaining the measurement results of the primary processedobject sensor 60 and the measurement results of the secondary processedobject sensor 70 with high accuracy. In addition, FIG. 11 is an example of the recovered amount of the primary treatment material, the return amount of the secondary treatment material, and the detection amount in this embodiment. As shown in FIG. 10 , the measurement results of the primary processedobject sensor 60 and the measurement results of the secondary processedobject sensor 70 are transmitted to the measurementresult acquisition unit 81 . Thecorrection unit 82 refers to the measurementresult acquisition unit 81 , and corrects the recovered amount of the primary processed product by the primary processedproduct sensor 60 with the returned amount of the secondary processed product by the secondary processedproduct sensor 70 .

具体而言，在作业对象区域中开始收获作业到一次处理物回收量达到规定量为止，校正部82对一次处理物回收量加上二次处理物返还量而校正。作业对象区域是联合收割机在田地中进行作物的割取作业的区域。如图11所示，从开始作物的收获作业到一次处理物回收量达到规定量(规定值)为止，即图11中的收割开始到t1为止，一次处理物回收量逐渐增大，二次处理物返还量急剧地(陡峭地)增大之后逐渐减少。因此，校正部82在从收割开始到t1为止，对由一次处理物传感器60检测出的一次处理物回收量加上二次处理物返还量而校正一次处理物传感器60的检测结果。Specifically, thecorrection unit 82 corrects by adding the recovered amount of the primary processed material to the recovered amount of the secondary processed material until the harvesting operation is started in the work target area until the recovered amount of the primary processed material reaches a predetermined amount. The work target area is an area where the combine harvester performs crop harvesting work in the field. As shown in Figure 11, from the start of crop harvesting until the recovery of the primary treatment reaches a specified amount (prescribed value), that is, from the start of harvesting in Figure 11 to t1, the recovery of the primary treatment gradually increases, and the recovery of the secondary treatment increases gradually. The amount of goods returned increases sharply (steeply) and then decreases gradually. Therefore, thecorrection part 82 corrects the detection result of the primary processedobject sensor 60 by adding the secondary processed object return amount to the primary processed object recovery amount detected by the primary processedobject sensor 60 by t1 from harvesting start.

另一方面，校正部82在收割并穿过作业对象区域之后从一次处理物回收量中减去二次处理物返还量而校正。收割并穿过作业对象区域之后是指，联合收割机的割取部4在田地中行驶穿过进行作物的割取作业的区域之后。在这种状态下，如图11所示，在从收割穿过经过了规定时间的t2之后，一次处理物回收量急剧地(陡峭地)增大之后逐渐减少，二次处理物返还量逐渐减少。因此，校正部82在从收割穿过经过了规定时间的t2之后，从由一次处理物传感器60检测出的一次处理物回收量中减去二次处理物返还量而校正一次处理物传感器60的检测结果。On the other hand, the correctingunit 82 corrects by subtracting the secondary processed material return amount from the primary processed material recovery amount after harvesting and passing through the work target area. After harvesting and passing through the work target area means after the reapingunit 4 of the combine has driven through the area where the crop reaping work is performed in the field. In this state, as shown in FIG. 11 , after the predetermined time t2 has elapsed from the harvest, the amount of recovered primary processing material increases sharply (steeply) and then gradually decreases, and the amount of secondary processing material returned gradually decreases. . Therefore, thecalibration unit 82 corrects the value of the primary processedproduct sensor 60 by subtracting the returned amount of the secondary processed product from the recovered amount of the primary processed product detected by the primary processedproduct sensor 60 after the predetermined time t2 has elapsed from harvesting. Test results.

由校正部82校正后的一次处理物回收量被传递到控制单元83。控制单元83基于校正的一次处理物回收量与二次处理物返还量，控制脱粒装置1。具体而言，如果一次处理物回收量超过第一阈值，并且二次处理物返还量为第二阈值以下，则控制单元83减小分选部42中的第一谷壳筛38以及第二谷壳筛39的至少某一方的漏下开度。由此，能够减少一次处理物回收量，增大二次处理物返还量，增大在脱粒装置1中分选的脱粒处理物的量，进一步提高分选精度。因而，能够减少混入一次处理物的夹杂物的量。The primary disposal recovery amount corrected by thecorrection unit 82 is transmitted to thecontrol unit 83 . Thecontrol unit 83 controls the threshingdevice 1 based on the corrected recovered amount of the primary processed material and the returned amount of the secondary processed material. Specifically, if the recovered amount of the primary processed material exceeds the first threshold and the returned amount of the secondary processed material is below the second threshold, thecontrol unit 83 reduces the number of thefirst chaff sieve 38 and the second grain sieve in thesorting unit 42 . The leakage opening of at least one side of theshell screen 39. Thereby, it is possible to reduce the recovery amount of the primary processed material, increase the returned amount of the secondary processed material, increase the amount of the threshing processed material sorted in the threshingdevice 1, and further improve the sorting accuracy. Therefore, the amount of inclusions mixed into the primary processed product can be reduced.

另外，优选的是，若一次处理物回收量比预先设定的小于第一阈值的第三阈值小，则控制单元83增大谷壳筛的漏下开度。由此，能够在一次处理物回收量为规定量以下的情况下增大一次处理物回收量。In addition, it is preferable that thecontrol unit 83 increases the opening of the chaff sieve if the recovery amount of the primary processed material is smaller than a preset third threshold smaller than the first threshold. Accordingly, when the recovered amount of the primary processed material is equal to or less than a predetermined amount, the recovered amount of the primary processed material can be increased.

另外，根据情况的不同，设想即使在第一谷壳筛38以及第二谷壳筛39的漏下开度变小的情况下，相对于一次处理物回收量比第一阈值大的状态继续或者二次处理物返还量为第二阈值以下的状态继续，二次处理物返还量的比率不变小，但这是因为向脱粒装置1供给的作物的量过多。因此，优选的是，即使在第一谷壳筛38以及第二谷壳筛39的漏下开度增大的情况下，特别是二次处理物返还量比第二阈值大时，进行机体框架2的行驶控制的行驶装置3也使机体框架2的行驶速度减少。由此，能够减少向脱粒装置1供给的作物的量，减少脱粒装置1中的脱粒量以及分选量。因而，例如在因在谷粒筛40中成为脱粒处理物堵塞的状态而二次处理物返还量增大的情况下，能够消除该脱粒处理物堵塞的状态。In addition, depending on the situation, it is assumed that even when the openings of thefirst chaff sieve 38 and thesecond chaff sieve 39 become smaller, the state in which the recovery amount of the primary processed product is larger than the first threshold value continues or The state in which the amount of returned secondary processed matter is equal to or less than the second threshold continues, and the ratio of the returned amount of secondary processed matter does not decrease, but this is because the amount of crops supplied to the threshingapparatus 1 is too large. Therefore, it is preferable that even if the openings of thefirst chaff sieve 38 and thesecond chaff sieve 39 are increased, especially when the return amount of the secondary processed material is larger than the second threshold value, the body frame is carried out. Thetravel device 3 of the travel control of 2 also reduces the travel speed of thebody frame 2 . Thereby, the quantity of the crops supplied to the threshingapparatus 1 can be reduced, and the threshing amount and the sorting amount in the threshingapparatus 1 can be reduced. Therefore, for example, when the amount of return of the secondary processed material increases due to the clogged state of the threshing processed material in the grain sieve 40 , the clogged state of the threshed processed material can be eliminated.

这种行驶装置3也可以构成为使机体框架2自动行驶。在该情况下，可以基于上述第一阈值、第二阈值降低机体框架2的行驶速度或使其停车。Such a travelingdevice 3 may also be configured to automatically travel thebody frame 2 . In this case, the travel speed of thebody frame 2 may be reduced or stopped based on the first threshold and the second threshold.

而且，优选的是，在由于意外的理由而第一谷壳筛38以及第二谷壳筛39的漏下开度变大后到经过预先设定的时间为止、二次处理物返还量相对于一次处理物回收量的比率不变小时，或在机体框架2的行驶速度减少到经过预先设定的时间为止、二次处理物返还量相对于一次处理物回收量的比率不变小时，行驶装置3使机体框架2停止。由此，能够暂时中断作物向脱粒装置1的供给，因此能够减少脱粒装置1中的脱粒处理以及分选处理的负载。因而，能够在当前进行对于脱粒装置1内的作物的处理，消除谷粒筛40中的脱粒处理物堵塞的状态。And, it is preferable that the amount of return of the secondary processed matter relative to the amount of the secondary processed material is returned after the opening of thefirst chaff sieve 38 and thesecond chaff sieve 39 becomes large due to an unexpected reason until a preset time has elapsed. The ratio of the recovery amount of the primary treatment remains constant, or until the running speed of thebody frame 2 is reduced to a preset time, and the ratio of the return amount of the secondary treatment to the recovery of the primary treatment remains small, the travelingdevice 3. Stop thebody frame 2. Thereby, since the supply of crops to the threshingapparatus 1 can be temporarily interrupted, the load of the threshing process and the sorting process in the threshingapparatus 1 can be reduced. Therefore, the processing with respect to the crop in the threshingapparatus 1 can be performed now, and the clogging of the threshing process material in the grain sieve 40 can be eliminated.

另外，在能够变更送尘阀53a的倾斜姿态的情况下，也可以构成为基于一次处理物回流量与二次处理物返还量变更该倾斜角度。In addition, when the inclination attitude|position of the dust-feedingvalve 53a can be changed, it may be comprised so that this inclination angle may be changed based on the return amount of primary processed object and the return amount of secondary processed object.

〔其他实施方式〕[Other Embodiments]

在上述实施方式中，说明了校正部82在作业对象区域中开始收获作业到一次处理物回收量达到规定量为止，对一次处理物回收量加上二次处理物返还量而校正的，但校正部82也可以构成为，在作业对象区域中开始收获作业到一次处理物回收量达到规定量为止，对一次处理物回收量加上预先设定的值(一定值、计算值)而校正。In the above-mentioned embodiment, it has been described that the correctingunit 82 starts the harvest operation in the work target area until the recovered amount of the primary processed material reaches a predetermined amount, and corrects by adding the returned amount of the secondary processed material to the recovered amount of the primary processed material. Theunit 82 may be configured to correct by adding a preset value (fixed value, calculated value) to the recovered amount of the primary processed material until the harvesting operation starts in the work target area until the recovered amount of the primary processed material reaches a predetermined amount.

在上述实施方式中，说明了校正部82在收割并穿过作业对象区域之后从一次处理物回收量中减去二次处理物返还量而校正，但校正部82也可以构成为，在收割并穿过作业对象区域之后，从一次处理物回收量中减去预先设定的值(一定值、计算值)而校正。In the above-mentioned embodiment, it has been described that the correctingunit 82 corrects by subtracting the returned amount of the secondary processed material from the recovered amount of the primary processed material after harvesting and passing through the work target area, but the correctingunit 82 may also be configured to After passing through the work target area, it is corrected by subtracting a preset value (fixed value, calculated value) from the amount of recovered primary disposal.

在上述实施方式中，列举联合收割机是普通型联合收割机的情况下的例子进行了说明，但联合收割机也可以是半喂入式联合收割机。In the said embodiment, although the example in the case where a combine was an ordinary type combine was mentioned and demonstrated, a combine may be a half-feed type combine.

4－2.第二实施方式4-2. Second Embodiment

接下来，对第二实施方式的联合收割机进行说明。本实施方式的联合收割机也构成为能够适当地存储从所脱粒的作物分选的谷粒。以下，对于本实施方式的联合收割机，列举普通型联合收割机为例进行说明。关于本实施方式的联合收割机的构成，与上述第一实施方式中的图1－图9中所示的构成相同，因此省略说明。以下，主要以与第一实施方式的不同点为中心进行说明。Next, the combine harvester of 2nd Embodiment is demonstrated. The combine harvester of this embodiment is also comprised so that the grain sorted from the threshed crop can be stored suitably. Hereinafter, an ordinary type combine will be given as an example and demonstrated about the combine of this embodiment. Since the structure of the combine of this embodiment is the same as the structure shown in FIGS. 1-9 in 1st Embodiment mentioned above, description is abbreviate|omitted. Hereinafter, the description will mainly focus on differences from the first embodiment.

图12是表示使用了一次处理物传感器60的测定结果以及二次处理物传感器70的测定结果的脱粒控制所涉及的功能部的框图。另外，图13是表示基于本实施方式中的一次处理物回收量与二次处理物返还量的控制状态的图。如图12所示，一次处理物传感器60的测定结果以及二次处理物传感器70的测定结果被传递到控制单元83。控制单元83在一次处理物回收量超过预先设定的第一阈值并且二次处理物返还量为预先设定的第二阈值以下时，减小谷壳筛的漏下开度。一次处理物回收量是由一次处理物传感器60的测定结果示出的一次处理物的回收量。第一阈值是对于一次处理物回收量设定的阈值，并且是为了在一次处理物回收量多的情况下抑制作为一次处理物的回收且使二次处理物返还装置32返还而设置的设定值。二次处理物返还量是由二次处理物传感器70的测定结果示出的二次处理物的返还量。第二阈值是对于二次处理物返还量设定的阈值，并且是为了在二次处理物返还量较少的情况下促进作为二次处理物的回收且使二次处理物返还装置32返还而设置的设定值。FIG. 12 is a block diagram showing functional units related to threshing control using the measurement results of the primary processedobject sensor 60 and the measurement results of the secondary processedobject sensor 70 . In addition, FIG. 13 is a diagram showing a control state based on the recovered amount of the primary processed material and the returned amount of the secondary processed material in the present embodiment. As shown in FIG. 12 , the measurement results of the primary processedproduct sensor 60 and the measurement results of the secondary processedproduct sensor 70 are transmitted to thecontrol unit 83 . Thecontrol unit 83 reduces the opening of the chaff sieve when the recovered amount of the primary processed material exceeds the preset first threshold and the returned amount of the secondary processed material is below the preset second threshold. The recovered amount of primary processed material is the recovered amount of primary processed material indicated by the measurement result of the primary processedmaterial sensor 60 . The first threshold is a threshold value set for the recovery amount of the primary disposal, and is set to suppress recovery as the primary disposal and return the secondarydisposal return device 32 when the recovery amount of the primary disposal is large. value. The returned amount of secondary processed material is the returned amount of secondary processed material indicated by the measurement result of the secondary processedmaterial sensor 70 . The second threshold is a threshold set for the return amount of the secondary processed object, and is set to promote recovery as the secondary processed object and to return the secondary processedobject return device 32 when the returned amount of the secondary processed object is small. Set the setpoint.

这里，关于一次处理物回收量以及二次处理物返还量，在一次处理物传感器60以及二次处理物传感器70的构成上，并不是始终得到由一定的值构成的测定结果。因此，控制单元83也可以推算一次处理物回收量以及二次处理物返还量各自的规定时间的平均值并用作上述测定结果，也可以使用在规定的定时获得的一次处理物回收量以及二次处理物返还量的瞬时值。另外，第一阈值与第二阈值既可以相互独立地设定，也可以相互建立关联地设定。Here, regarding the recovered amount of the primary processed matter and the returned amount of the secondary processed matter, the configuration of the primary processedmatter sensor 60 and the secondary processedmatter sensor 70 does not always give a measurement result consisting of a constant value. Therefore, thecontrol unit 83 may estimate the average value of each of the primary processed product recovery amount and the secondary processed product return amount at a predetermined time and use it as the above-mentioned measurement result, or may use the primary processed product recovery amount and the secondary processed product recovery amount obtained at a predetermined timing. The instantaneous value of the returned amount of the disposal. In addition, the first threshold and the second threshold may be set independently of each other, or may be set in association with each other.

更具体而言，如果一次处理物回收量超过第一阈值，并且二次处理物返还量为第二阈值以下，则控制单元83减小分选部42中的第一谷壳筛38以及第二谷壳筛39的至少某一方的漏下开度。这种一次处理物回收量超过预先设定的第一阈值并且二次处理物返还量为预先设定的第二阈值以下的状态在图13中表示为区分A1。由此，能够减少一次处理物回收量，增大二次处理物返还量，增大在脱粒装置1中分选的脱粒处理物的量，进一步提高分选精度。因而，能够减少混入一次处理物的夹杂物的量。More specifically, if the recovered amount of the primary processed matter exceeds the first threshold and the returned amount of the secondary processed matter is below the second threshold, thecontrol unit 83 reduces thefirst chaff sieve 38 and the second chaff sieve in thesorting section 42 . The opening degree of leakage of at least one side of thechaff sieve 39. The state in which the recovered amount of primary processed materials exceeds a preset first threshold and the returned amount of secondary processed materials is equal to or less than a preset second threshold is shown as section A1 in FIG. 13 . Thereby, it is possible to reduce the recovery amount of the primary processed material, increase the returned amount of the secondary processed material, increase the amount of the threshing processed material sorted in the threshingdevice 1, and further improve the sorting accuracy. Therefore, the amount of inclusions mixed into the primary processed product can be reduced.

另外，优选的是，若一次处理物回收量比预先设定的小于第一阈值小的第三阈值小，则控制单元83增大谷壳筛的漏下开度。由此，能够在一次处理物回收量为规定量以下的情况下增大一次处理物回收量。这种一次处理物回收量小于预先设定的第三阈值的状态在图13中表示为区分B1。In addition, it is preferable that thecontrol unit 83 increases the opening of the chaff sieve if the recovery amount of the primary processed material is smaller than a preset third threshold smaller than the first threshold. Accordingly, when the recovered amount of the primary processed material is equal to or less than a predetermined amount, the recovered amount of the primary processed material can be increased. The state in which the recovery amount of the primary processed material is smaller than the preset third threshold value is shown as division B1 in FIG. 13 .

另外，根据情况的不同，设想即使在第一谷壳筛38以及第二谷壳筛39的漏下开度减小的情况下，相对于一次处理物回收量比第一阈值大的状态继续或者二次处理物返还量为第二阈值以下的状态继续，二次处理物返还量的比率不变小，但这是因为向脱粒装置1供给的作物的量过多。因此，优选的是，即使在第一谷壳筛38以及第二谷壳筛39的漏下开度增大的情况下，特别是二次处理物返还量比第二阈值大时，进行机体框架2的行驶控制的行驶装置3也使机体框架2的行驶速度减少。这种二次处理物返还量比预先设定的第二阈值大的状态在图13中表示为区分C1。由此，能够减少向脱粒装置1供给的作物的量，减少脱粒装置1中的脱粒量以及分选量。因而，例如在因在谷粒筛40中成为脱粒处理物堵塞的状态而二次处理物返还量增大的情况下，能够消除该脱粒处理物堵塞的状态。In addition, depending on the situation, it is assumed that even when the openings of thefirst chaff sieve 38 and thesecond chaff sieve 39 decrease, the state in which the recovery amount of the primary processed product is larger than the first threshold value continues or The state in which the amount of returned secondary processed matter is equal to or less than the second threshold continues, and the ratio of the returned amount of secondary processed matter does not decrease, but this is because the amount of crops supplied to the threshingapparatus 1 is too large. Therefore, it is preferable that even if the openings of thefirst chaff sieve 38 and thesecond chaff sieve 39 are increased, especially when the return amount of the secondary processed material is larger than the second threshold value, the body frame is carried out. Thetravel device 3 of the travel control of 2 also reduces the travel speed of thebody frame 2 . The state in which the return amount of such secondary processed objects is larger than the preset second threshold value is shown as a segment C1 in FIG. 13 . Thereby, the quantity of the crops supplied to the threshingapparatus 1 can be reduced, and the threshing amount and the sorting amount in the threshingapparatus 1 can be reduced. Therefore, for example, when the amount of return of the secondary processed material increases due to the clogged state of the threshing processed material in the grain sieve 40 , the clogged state of the threshed processed material can be eliminated.

这种行驶装置3也可以构成为使机体框架2自动行驶。在该情况下，可以基于上述第一阈值、第二阈值降低机体框架2的行驶速度或使其停车。Such a travelingdevice 3 may also be configured to automatically travel thebody frame 2 . In this case, the travel speed of thebody frame 2 may be reduced or stopped based on the first threshold and the second threshold.

而且，优选的是，在由于意外的理由而第一谷壳筛38以及第二谷壳筛39的漏下开度变大后到经过预先设定的时间为止、二次处理物返还量相对于一次处理物回收量的比率不变小时，或在机体框架2的行驶速度减少到经过预先设定的时间为止、二次处理物返还量相对于一次处理物回收量的比率不变小时，行驶装置3使机体框架2停止。由此，能够暂时中断作物向脱粒装置1的供给，因此能够减少脱粒装置1中的脱粒处理以及分选处理的负载。因而，能够在当前进行对于脱粒装置1内的作物的处理，消除谷粒筛40中的脱粒处理物堵塞的状态。And, it is preferable that the amount of return of the secondary processed matter relative to the amount of the secondary processed material is returned after the opening of thefirst chaff sieve 38 and thesecond chaff sieve 39 becomes large due to an unexpected reason until a preset time has elapsed. The ratio of the recovery amount of the primary treatment remains constant, or until the running speed of thebody frame 2 is reduced to a preset time, and the ratio of the return amount of the secondary treatment to the recovery of the primary treatment remains small, the travelingdevice 3. Stop thebody frame 2. Thereby, since the supply of crops to the threshingapparatus 1 can be temporarily interrupted, the load of the threshing process and the sorting process in the threshingapparatus 1 can be reduced. Therefore, the processing with respect to the crop in the threshingapparatus 1 can be performed now, and the clogging of the threshing process material in the grain sieve 40 can be eliminated.

在上述实施方式中，说明了行驶装置3在二次处理物返还量比第二阈值大时使机体框架2的行驶速度减少，但行驶装置3也可以构成为在二次处理物返还量比第二阈值大时也不减少机体框架2的行驶速度。In the above-mentioned embodiment, the travelingdevice 3 has been described to reduce the traveling speed of thebody frame 2 when the return amount of the secondary processed objects is larger than the second threshold value, but the travelingdevice 3 may be configured so that the returned amount of the secondary processed objects is larger than the second threshold value. When the second threshold is large, the running speed of thebody frame 2 is not reduced either.

在上述实施方式中，说明了行驶装置3使机体框架2自动行驶，但也可以构成为机体框架2不自动行驶。In the above-mentioned embodiment, it was described that the travelingdevice 3 automatically travels thebody frame 2 , but it may be configured so that thebody frame 2 does not travel automatically.

在上述实施方式中，说明了若一次处理物回收量小于比第一阈值小的第三阈值小，则谷壳筛增大漏下开度，但谷壳筛也可以构成为，即使在一次处理物回收量小于比第一阈值小的第三阈值小的情况下，漏下开度也不会变大。In the above-mentioned embodiment, it has been explained that if the recovery amount of the primary processed material is smaller than the third threshold value smaller than the first threshold value, the chaff sieve increases the opening of the drain, but the chaff sieve can also be configured so that even after one treatment Even when the amount of recovered matter is smaller than the third threshold smaller than the first threshold, the leak opening does not increase.

在上述实施方式中，虽然说明了基于一次处理物回流量与二次处理物返还量变更谷壳筛的漏下开度的构成，但在能够变更送尘阀53a的倾斜姿态的情况下，也可以构成为基于一次处理物回流量与二次处理物返还量变更该倾斜角度。In the above-mentioned embodiment, although the configuration in which the opening degree of the chaff sieve is changed based on the return amount of the primary processed product and the returned amount of the secondary processed product has been described, if the inclined posture of thedust sending valve 53a can be changed, the The angle of inclination may be changed based on the return amount of the primary processed product and the return amount of the secondary processed product.

4－3.第三实施方式4-3. Third Embodiment

接下来，对第三实施方式的联合收割机进行说明。本实施方式的联合收割机构成为能够判定从作物脱粒的脱粒处理物在脱粒装置内是否堵塞。以下，对于本实施方式的联合收割机，列举普通型联合收割机为例进行说明。关于本实施方式的联合收割机的构成，与上述第一实施方式中的图1－图9中所示的构成相同，因此省略说明。以下，主要以与第一实施方式的不同点为中心进行说明。Next, the combine harvester which concerns on 3rd Embodiment is demonstrated. The combine harvesting mechanism of this embodiment becomes able to determine whether the threshing processed material threshed from a crop clogs up in a threshing apparatus. Hereinafter, an ordinary type combine will be given as an example and demonstrated about the combine of this embodiment. Since the structure of the combine of this embodiment is the same as the structure shown in FIGS. 1-9 in 1st Embodiment mentioned above, description is abbreviate|omitted. Hereinafter, the description will mainly focus on differences from the first embodiment.

图14是表示使用了一次处理物传感器60的测定结果以及二次处理物传感器70的测定结果的、分选部42中的脱粒处理物的堵塞判定所涉及的功能部的框图。如图14所示，一次处理物传感器60的测定结果以及二次处理物传感器70的测定结果被传递到判定部80。判定部80根据二次处理物返还量相对于一次处理物回收量的比率，判定在分选部42中脱粒处理物是否堵塞。一次处理物回收量是由一次处理物传感器60的测定结果示出的一次处理物的回收量。二次处理物返还量是由二次处理物传感器70的测定结果示出的二次处理物的返还量。二次处理物返还量相对于一次处理物回收量的比率是指二次处理物的返还量除以一次处理物的回收量而得的值。这里，一次处理物回收量以及二次处理物返还量在一次处理物传感器60以及二次处理物传感器70的构成上，并不是始终得到由一定的值构成的测定结果。因此，判定部80也可以推算一次处理物回收量以及二次处理物返还量各自的规定时间的平均值而求出上述比率，也可以使用在规定的定时获得的一次处理物回收量以及二次处理物返还量的瞬时值求出上述比率。判定部80的判定结果被传递到控制单元83。FIG. 14 is a block diagram showing a functional unit related to clogging determination of the threshing processed product in thesorting unit 42 using the measurement result of the primary processedproduct sensor 60 and the measurement result of the secondary processedproduct sensor 70 . As shown in FIG. 14 , the measurement results of the primary processedobject sensor 60 and the measurement results of the secondary processedobject sensor 70 are transmitted to thedetermination unit 80 . Thedetermination unit 80 determines whether or not the threshing processed material is clogged in thesorting unit 42 based on the ratio of the returned amount of the secondary processed material to the recovered amount of the primary processed material. The recovered amount of primary processed material is the recovered amount of primary processed material indicated by the measurement result of the primary processedmaterial sensor 60 . The returned amount of secondary processed material is the returned amount of secondary processed material indicated by the measurement result of the secondary processedmaterial sensor 70 . The ratio of the returned amount of secondary treated matter to the recovered amount of primary treated matter is a value obtained by dividing the returned amount of secondary treated matter by the recovered amount of primary treated matter. Here, the recovered amount of the primary processed material and the returned amount of the secondary processed material do not always obtain measurement results consisting of constant values due to the configuration of the primary processedmaterial sensor 60 and the secondary processedmaterial sensor 70 . Therefore, the judgingunit 80 may calculate the average value of the recovered amount of the primary processed material and the returned amount of the secondary processed material in a predetermined period of time to obtain the ratio, or may use the recovered amount of the primary processed material and the returned amount of the secondary processed material obtained at a predetermined timing. The above-mentioned ratio is obtained from the instantaneous value of the return amount of the processed goods. The determination result of thedetermination section 80 is transmitted to thecontrol unit 83 .

这里，若二次处理物返还量过多，则有时会超过二次处理物返还装置32的处理能力。因此，二次处理物返还量越多，即二次处理物返还量相对于一次处理物回收量的比率越大，控制单元83越是增大第一谷壳筛38的漏下开度。由此，从第一谷壳筛38向一次处理物回收部26漏下的处理物的量增大，到达二次处理物返还装置32的处理物的量减少，因此能够减少二次处理物返还量。Here, if the amount of returned secondary processed objects is too large, the processing capacity of the secondary processedobject returning device 32 may be exceeded. Therefore, the more the return amount of the secondary processed matter is, that is, the larger the ratio of the returned amount of the secondary processed matter to the recovered amount of the primary processed matter is, the more thecontrol unit 83 increases the leakage opening of thefirst chaff sieve 38 . As a result, the amount of the processed product that leaks from thefirst chaff sieve 38 to the primary processedproduct recovery unit 26 increases, and the amount of the processed product that reaches the secondary processedproduct returning device 32 decreases, so that the return of the secondary processed product can be reduced. quantity.

然而，即使在第一谷壳筛38的漏下开度变大的情况下，有时二次处理物返还量相对于一次处理物回收量的比率也不变小。作为该原因，认为是从第一谷壳筛38漏下的脱粒处理物在谷粒筛40堵塞而没有漏下到一次处理物回收部26。在该情况下，判定部80判定为在谷粒筛40脱粒处理物堵塞。如此，在本实施方式的联合收割机中，能够根据二次处理物返还量相对于一次处理物回收量的比率判定在谷粒筛40中脱粒处理物是否堵塞。However, even when the opening degree of the drain of the1st chaff sieve 38 becomes large, the ratio of the return amount of a secondary processed object with respect to the recovery amount of a primary processed object may not become small. As this reason, it is thought that the threshing processed material which leaked from the1st chaff sieve 38 clogged the grain sieve 40 and did not leak down to the primary processedmaterial recovery part 26. In this case, thedetermination part 80 determines that the threshing processed material clogged the grain sieve 40 . Thus, in the combine harvester of this embodiment, it can be judged whether the threshing processed material clogged the grain sieve 40 from the ratio of the secondary processed material return amount with respect to the primary processed material recovery amount.

另外，为了消除谷粒筛40处的脱粒处理物的堵塞，考虑减少向脱粒装置1供给的作物的量。如果减少行驶速度，则向脱粒装置1供给的作物的量减少，能够消除谷粒筛40中的脱粒处理物的堵塞。因此，控制单元83优选为，在即使在第一谷壳筛38的漏下开度变大的情况下、二次处理物返还量相对于一次处理物回收量的比率也不变小时，行驶装置3使机体框架2的行驶速度减少。Moreover, in order to eliminate clogging of the threshing processed material at the grain sieve 40, it is conceivable to reduce the quantity of the crops supplied to the threshingapparatus 1. If the running speed is reduced, the amount of crops supplied to the threshingapparatus 1 will decrease, and clogging of the threshing processed product in the grain sieve 40 can be eliminated. Therefore, it is preferable that thecontrol unit 83 is such that the ratio of the return amount of the secondary processed matter to the recovered amount of the primary processed matter does not become small even when the opening of thefirst chaff sieve 38 becomes large, and the travelingdevice 3. Decrease the running speed of thebody frame 2.

而且，在第一谷壳筛38的漏下开度变大到经过预先设定的时间为止、二次处理物返还量相对于一次处理物回收量的比率不变小时，或在机体框架2的行驶速度减少到经过预先设定的时间为止、二次处理物返还量相对于一次处理物回收量的比率不变小时，行驶装置3使机体框架2停止，优选的是。由此，能够暂时中断作物向脱粒装置1的供给，因此能够减少脱粒装置1中的脱粒处理以及分选处理的负载。因而，能够在当前进行对于脱粒装置1内的作物的处理，消除谷粒筛40中的脱粒处理物堵塞的状态。And until the opening of thefirst chaff sieve 38 becomes large until the preset time passes, the ratio of the return amount of the secondary treated matter relative to the recovered amount of the treated matter does not become small, or in thebody frame 2 It is preferable that the travelingdevice 3 stops thebody frame 2 until the travel speed decreases until a preset time elapses and the ratio of the returned amount of the secondary processed matter to the recovered amount of the primary disposed matter does not become smaller. Thereby, since the supply of crops to the threshingapparatus 1 can be temporarily interrupted, the load of the threshing process and the sorting process in the threshingapparatus 1 can be reduced. Therefore, the processing with respect to the crop in the threshingapparatus 1 can be performed now, and the clogging of the threshing process material in the grain sieve 40 can be eliminated.

另外，也可以构成为，在即使在第一谷壳筛38的漏下开度变大的情况下、二次处理物返还量相对于一次处理物回收量的比率也不变小时，由报告部91进行报告。由此，能够向操作人员、周围告知在谷粒筛40中脱粒处理物堵塞的状态。In addition, it may also be configured such that the ratio of the returned amount of the secondary processed matter to the recovered amount of the primary processed matter does not become small even when the opening of thefirst chaff sieve 38 becomes large, and thereporting unit 91 to report. Thereby, the state which clogged the threshing processed material in the grain sieve 40 can be notified to an operator and surroundings.

〔其他实施方式〕[Other Embodiments]

在上述实施方式中，说明了判定部80在即使在二次处理物返还量相对于一次处理物回收量的比率越大、漏下开度越大的情况下该比率也不变小时，判定为在谷粒筛40中脱粒处理物堵塞，但判定部80也可以在即使在二次处理物返还量相对于一次处理物回收量的比率越大、漏下开度越大的情况下该比率也不变小时以外，判定在谷粒筛40中脱粒处理物是否堵塞。In the above-mentioned embodiment, it has been explained that the judgingunit 80 judges that even if the ratio of the returned amount of secondary processed objects to the recovered amount of primary processed objects is larger and the ratio of the leakage opening is larger, the ratio does not become smaller. The grain sieve 40 is clogged with threshed processed matter, but the judgingunit 80 may determine that even if the ratio of the returned amount of the secondary processed matter to the recovered amount of the primary processed matter is larger and the opening degree of the drain is larger, the ratio may be larger. Except that it does not become small, it is determined whether the threshed processed material clogs the grain sieve 40 .

在上述实施方式中，说明了行驶装置3在即使在谷壳筛的漏下开度变大的情况下、二次处理物返还量相对于一次处理物回收量的比率也不变小时，使机体框架2的行驶速度减少，但行驶装置3也可以构成为，在二次处理物返还量相对于一次处理物回收量的比率不变小时，不使机体框架2的行驶速度减少。In the above-mentioned embodiment, it was explained that even if the opening of the chaff sieve becomes large, the ratio of the return amount of the secondary processed matter to the recovered amount of the primary processed matter does not become small, so that the machine body The traveling speed of theframe 2 is reduced, but the travelingdevice 3 may be configured so as not to reduce the traveling speed of thebody frame 2 unless the ratio of the returned amount of the secondary treated matter to the recovered amount of the primary disposed matter remains small.

在上述实施方式中，说明了行驶装置3在从谷壳筛的漏下开度变大到经过预先设定的时间为止、二次处理物返还量相对于一次处理物回收量的比率不变小时，使机体框架2停车，但行驶装置3也可以构成为，在从谷壳筛的漏下开度变大到行驶预先设定的距离为止、二次处理物返还量相对于一次处理物回收量的比率不变小时，使机体框架2停车。In the above-mentioned embodiment, it was described that the ratio of the return amount of the secondary processed matter to the recovered amount of the primary processed matter does not become small until the preset time elapses from when the opening of the chaff sieve becomes larger. , thebody frame 2 is parked, but thetravel device 3 can also be configured such that the return amount of the secondary treatment is relative to the recovery amount of the primary treatment when the opening of the chaff sieve becomes larger to travel a preset distance. When the ratio is constant, thebody frame 2 is stopped.

在上述实施方式中，说明了行驶装置3在谷壳筛的漏下开度变大到经过预先设定的时间为止、二次处理物返还量相对于一次处理物回收量的比率不变小时，使机体框架2停车，但行驶装置3也可以构成为不使机体框架2停车。In the above-mentioned embodiment, it has been described that the ratio of the return amount of the secondary processed matter to the recovered amount of the primary processed matter does not become small until the opening degree of the chaff sieve of the chaff sieve becomes large until a preset time elapses. Thebody frame 2 is stopped, but thetravel device 3 may be configured so as not to stop thebody frame 2 .

在上述实施方式中，说明了具备在即使在谷壳筛的漏下开度变大的情况下、二次处理物返还量相对于一次处理物回收量的比率也不变小时进行报告的报告部91，但也可以构成为不具备报告部91。In the above-mentioned embodiment, it has been described that there is a reporting unit that reports that the ratio of the return amount of the secondary processed product to the recovered amount of the primary processed product does not become smaller even when the opening degree of the chaff sieve becomes larger. 91, but it may also be configured without thereporting unit 91.

在上述实施方式中，列举联合收割机为普通型联合收割机的情况下的例子进行了说明，但联合收割机也可以是半喂入式联合收割机。In the said embodiment, although the example in the case where a combine was an ordinary type combine was given and demonstrated, a combine may be a half-feed type combine.

4－4.第四实施方式4-4. Fourth Embodiment

接下来，对第四实施方式的联合收割机进行说明。本实施方式的联合收割机构成为能够存储从脱粒的作物适当地分选的谷粒。以下，对于本实施方式的联合收割机，列举普通型联合收割机为例进行说明。关于本实施方式的联合收割机的构成，与上述第一实施方式中的图1－图9中所示的构成相同，因此省略说明。以下，主要以与第一实施方式的不同点为中心进行说明。Next, the combine harvester which concerns on 4th Embodiment is demonstrated. The combine of the present embodiment can store grains appropriately sorted from threshed crops. Hereinafter, an ordinary type combine will be given as an example and demonstrated about the combine of this embodiment. Since the structure of the combine of this embodiment is the same as the structure shown in FIGS. 1-9 in 1st Embodiment mentioned above, description is abbreviate|omitted. Hereinafter, the description will mainly focus on differences from the first embodiment.

图15是表示使用了一次处理物传感器60的测定结果以及二次处理物传感器70的测定结果的脱粒控制所涉及的功能部的框图。如图15所示，一次处理物传感器60的测定结果以及二次处理物传感器70的测定结果传递到参数决定部84。参数决定部84根据二次处理物返还量相对于一次处理物回收量的比率决定脱粒装置1的控制参数。一次处理物回收量是由一次处理物传感器60的测定结果示出的一次处理物的回收量。二次处理物返还量是由二次处理物传感器70的测定结果示出的二次处理物的返还量。二次处理物返还量相对于一次处理物回收量的比率是二次处理物的返还量除以一次处理物的回收量而得的值。这里，一次处理物回收量以及二次处理物返还量在一次处理物传感器60以及二次处理物传感器70的构成上，并不是始终得到由一定的值构成的测定结果。因此，参数决定部84也可以推算一次处理物回收量以及二次处理物返还量各自的规定时间的平均值来求出上述比率，也可以使用在规定的定时获得的一次处理物回收量以及二次处理物返还量的瞬时值求出上述比率。FIG. 15 is a block diagram showing functional units related to threshing control using the measurement results of the primary processedobject sensor 60 and the measurement results of the secondary processedobject sensor 70 . As shown in FIG. 15 , the measurement results of the primary processedproduct sensor 60 and the measurement results of the secondary processedproduct sensor 70 are transmitted to theparameter determination unit 84 . Theparameter determination part 84 determines the control parameter of the threshingapparatus 1 from the ratio of the return amount of a secondary processing object with respect to the recovery amount of a primary processing object. The recovered amount of primary processed material is the recovered amount of primary processed material indicated by the measurement result of the primary processedmaterial sensor 60 . The returned amount of secondary processed material is the returned amount of secondary processed material indicated by the measurement result of the secondary processedmaterial sensor 70 . The ratio of the returned amount of secondary processed materials to the recovered amount of primary processed materials is a value obtained by dividing the returned amount of secondary processed materials by the recovered amount of primary processed materials. Here, the recovered amount of the primary processed material and the returned amount of the secondary processed material do not always obtain measurement results consisting of constant values due to the configuration of the primary processedmaterial sensor 60 and the secondary processedmaterial sensor 70 . Therefore, theparameter determination unit 84 may calculate the average value of each of the primary disposed material recovery amount and the secondary disposed matter return amount at a predetermined time to obtain the above-mentioned ratio, or may use the primary disposed matter recovery amount and the secondary disposed matter return amount obtained at predetermined timings. The above-mentioned ratio is obtained from the instantaneous value of the return amount of the secondary disposal.

脱粒装置1的控制参数是设定脱粒装置1的能力的设备设定值，具体而言相当于能够设定脱粒装置1所具备的脱粒部41的脱粒能力的脱粒参数、能够设定分选部42的分选能力的分选参数。能够设定脱粒部41中的脱粒能力的脱粒参数相当于设定脱粒筒22的旋转支轴55的旋转速度的设定值、设定送尘阀53a相对于顶板53的安装角度的设定值。另外，能够设定分选部42中的分选能力的分选参数相当于设定来自风选机19的分选风的风量的设定值、设定谷壳筛的漏下开度的设定值、设定使摆动分选装置24摆动的摆动驱动机构43的摆动速度、摆动量的设定值。进而，通过增减机体框架2的行驶速度，能够使联合收割机割取的作物的量变化。因而，机体框架2的行驶速度也包含在控制参数内。The control parameter of the threshingdevice 1 is an equipment setting value for setting the capability of the threshingdevice 1, and specifically corresponds to a threshing parameter capable of setting the threshing ability of the threshingpart 41 included in the threshingdevice 1, and a sorting part capable of setting 42 sorting parameters for sorting capacity. The threshing parameters capable of setting the threshing ability in the threshingunit 41 correspond to the set value for setting the rotation speed of the rotating shaft 55 of the threshingcylinder 22 and the set value for setting the installation angle of thedust delivery valve 53a with respect to thetop plate 53 . In addition, the sorting parameter which can set the sorting ability in the sortingpart 42 is equivalent to setting the set value of the air volume of the sorting wind from the winnowingmachine 19, and setting the opening degree of the chaff sieve. Fixed value, set the setting value of the swing speed and swing amount of theswing drive mechanism 43 that swings theswing sorting device 24 . Furthermore, the amount of crops harvested by the combine can be changed by increasing or decreasing the running speed of thebody frame 2 . Therefore, the travel speed of thebody frame 2 is also included in the control parameters.

参数决定部84通过变更上述的控制参数来进行决定，以使摆动分选装置24的分选能力、即由一次处理物回收部26回收的一次处理物的量相对于从筛网23漏下的处理物的量的比例即分选度(或者分选效率)变得适当。Theparameter determining part 84 is determined by changing the above-mentioned control parameters, so that the sorting capability of theswing sorting device 24, that is, the amount of the primary processed product recovered by the primary processedproduct recovery part 26 is relatively small compared to the amount of the primary processed product that is leaked from thescreen 23. The ratio of the amount of processed matter, that is, the degree of separation (or separation efficiency) becomes appropriate.

如图16所示，参数决定部84优选的是构成为，在设定规定的控制参数时，对于二次处理物返还量相对于一次处理物回收量的比率预先设定第一阈值与比该第一阈值大的第二阈值，将这些第一阈值与第二阈值之间作为设定范围来设定控制参数。由此，能够设定控制参数的最小值、最大值，因此能够确保控制量。As shown in FIG. 16 , theparameter determination unit 84 is preferably configured such that when setting a predetermined control parameter, a first threshold value and a ratio of the ratio of the returned amount of the secondary treated matter to the recovered amount of the primary disposed matter are set in advance. The control parameter is set with the second threshold larger than the first threshold and the range between these first thresholds and the second threshold as a setting range. Thereby, since the minimum value and maximum value of a control parameter can be set, a control amount can be ensured.

返回图15，控制单元83基于控制参数控制脱粒装置1。即，控制单元83通过上述的控制参数，控制脱粒装置1的脱粒部41以及分选部42。在如此控制的脱粒装置1中，一次处理物传感器60以及二次处理物传感器70分别测定回收量与返还量，进而由参数决定部84决定控制参数，由控制单元83控制脱粒装置1。因而，控制单元83基于一次处理物传感器60以及二次处理物传感器70各自的测定结果，进行反馈控制，在联合收割机进行收获作业的过程中，能够实时地设定与作业状况相应的适当的控制参数，适当地进行收获作业。Returning to Fig. 15, thecontrol unit 83 controls the threshingdevice 1 based on the control parameters. That is, thecontrol unit 83 controls the threshingpart 41 and the sortingpart 42 of the threshingapparatus 1 by the above-mentioned control parameter. In the threshingdevice 1 controlled in this way, the primary processedobject sensor 60 and the secondary processedobject sensor 70 respectively measure the recovered amount and the returned amount, and theparameter determination part 84 determines control parameters, and thecontrol unit 83 controls the threshingdevice 1 . Therefore, thecontrol unit 83 performs feedback control based on the respective measurement results of the primary processedobject sensor 60 and the secondary processedobject sensor 70, and can set appropriate parameters corresponding to the working conditions in real time while the combine harvester is harvesting. Control parameters for proper harvesting.

具体而言，如图17所示，二次处理物返还量相对于一次处理物回收量的比率越大，谷壳筛越是增大漏下开度，二次处理物返还量相对于一次处理物回收量的比率越大，风选机19越是增大分选风的风量。在二次处理物返还量相对于一次处理物回收量的比率较大的情况下，有可能在摆动分选装置24中不作为一次处理物回收、并且不作为二次处理物返还、而是向摆动分选装置24的后方作为三次处理物输送的量较多。因此，在二次处理物返还量相对于一次处理物回收量的比率较大的情况下，通过将谷壳筛的漏下开度设定得较大，能够使分选处理物容易向一次处理物回收部26、二次处理物回收部27漏下，通过增大风选机19的分选风的风量，能够在摆动分选装置24的后方输送分选处理物以外的物体。由此，能够减少作为三次处理物输送那样的三次处理损失。另一方面，在二次处理物返还量相对于一次处理物回收量的比率较小的情况下，有可能分选精度过高，在摆动分选装置24中不作为一次处理物回收而是输送到二次处理物回收部27的量较多。因此，在二次处理物返还量相对于一次处理物回收量的比率较小的情况下，通过将谷壳筛的漏下开度设定得较小，能够使分选处理物容易向一次处理物回收部26漏下，通过减少风选机19的分选风的风量，能够使分选处理物难以输送到摆动分选装置24的后方。由此，容易作为一次处理物回收。另外，在图12中，用同一特性表示漏下开度与二次处理物返还量相对于一次处理物回收量的比率的关系、和风量与二次处理物返还量相对于一次处理物回收量的比率的关系，但也可以设为相互不同的特性，也可以按照作物的每个种类分别变更。Specifically, as shown in Figure 17, the greater the ratio of the returned amount of secondary processed materials to the recovered amount of primary processed materials, the greater the opening of the chaff sieve, and the greater the ratio of the returned amount of secondary processed materials to the recovered amount of primary processed materials. The larger the ratio of the recovered material, the more thewind separator 19 increases the air volume of the sorting wind. When the ratio of the returned amount of secondary treated matter to the recovered amount of the primary treated matter is large, it may not be recovered as the primary treated matter in theswing sorting device 24, and not returned as the secondary treated matter, but to The rear of theswing sorting device 24 transports a large amount as the tertiary processed objects. Therefore, when the ratio of the return amount of the secondary treatment to the recovery of the primary treatment is large, by setting the opening degree of the chaff sieve to be larger, it is possible to easily transfer the sorting treatment to the primary treatment. Theobject recovery part 26 and the secondary processedobject recovery part 27 are dropped, and by increasing the air volume of the sorting air of the winnowingmachine 19, objects other than the sorting process can be transported behind the swingingsorting device 24. Thereby, it is possible to reduce the tertiary treatment loss that is transported as the tertiary treatment product. On the other hand, when the ratio of the returned amount of secondary processed objects to the recovered amount of primary processed objects is small, the sorting accuracy may be too high, and theswing sorter 24 is not recovered as primary processed objects but transported. The amount to the secondary processedmaterial recovery unit 27 is relatively large. Therefore, when the ratio of the return amount of the secondary processed matter to the recovered amount of the primary processed matter is small, by setting the lower opening of the chaff sieve to be small, it is possible to easily transfer the sorted processed matter to the primary processing. Thematerial recovery part 26 leaks down, and by reducing the air volume of the sorting wind of the winnowingmachine 19, it is possible to make it difficult for the sorting process to be transported to the rear of theswing sorting device 24. Thereby, it becomes easy to collect|recover as a primary disposal object. In addition, in Fig. 12, the relationship between the opening degree of the drain and the ratio of the return amount of the secondary treated matter to the recovered amount of the primary treated matter, and the relationship between the air volume and the returned amount of the secondary treated matter relative to the recovered amount of the primary treated matter are shown by the same characteristics. However, the characteristics may be different from each other, or may be changed for each type of crop.

另外，根据情况的不同，设想即使在谷壳筛的漏下开度变大且风选机19的分选风的风量增大的情况下，二次处理物返还量相对于一次处理物回收量的比率也不变小，但这是因为向脱粒装置1供给的作物的量过多。因此，优选的是，在即使在谷壳筛的漏下开度变大且风选机19的分选风的风量增大的情况下、二次处理物返还量相对于一次处理物回收量的比率也不变小时，行驶装置3使机体框架2的行驶速度减少。由此，向脱粒装置1供给的作物的量变少，能够减少脱粒装置1中的脱粒量以及分选量，因此能够适当地进行分选处理。In addition, depending on the situation, it is assumed that even if the opening of the chaff sieve becomes larger and the air volume of the sorting air of the winnowingmachine 19 increases, the return amount of the secondary processed matter will be higher than the amount of the primary processed matter recovered. The ratio of is not small, but this is because the amount of crops supplied to the threshingdevice 1 is too much. Therefore, it is preferable that the return amount of the secondary processed matter is equal to the amount of recovered primary processed matter even when the opening of the chaff sieve becomes large and the air volume of the sorting air of thewind separator 19 increases. The travelingdevice 3 reduces the traveling speed of thebody frame 2 even if the ratio does not become smaller. Thereby, since the quantity of the crops supplied to the threshingapparatus 1 becomes small and the threshing amount and the sorting amount in the threshingapparatus 1 can be reduced, it becomes possible to perform a sorting process suitably.

而且，优选的是，在由于意外的理由而谷壳筛的漏下开度变大、风选机19的分选风的风量增大到经过预先设定的时间为止、二次处理物返还量相对于一次处理物回收量的比率不变小时，或机体框架2的行驶速度减少到经过预先设定的时间为止、二次处理物返还量相对于一次处理物回收量的比率不变小时，行驶装置3使机体框架2停止。由此，能够暂时中断作物向脱粒装置1的供给，因此能够减少脱粒装置1中的脱粒处理以及分选处理的负载。因而，能够在当前进行对于脱粒装置1内的作物的处理。And, it is preferable that the opening of the chaff sieve becomes larger due to unexpected reasons, and the air volume of the sorting air of the winnowingmachine 19 is increased until the preset time passes, and the return amount of the secondary processed material When the ratio of the recovery amount of the primary treatment material remains constant, or the running speed of thebody frame 2 decreases until a preset time elapses, and the ratio of the return amount of the secondary treatment material to the recovery amount of the primary treatment material remains small, the driving Thedevice 3 stops thebody frame 2 .
