業が行えるものを提供せんとして創作したものである。By the way, in order to improve the performance of the threshing machine in order to meet the demand for higher performance of the combine, it is necessary to close the handling room and the processing room together with both chambers. It is essential to further improve the sorting performance of the rocking sorting body that sorts the threshed material.In order to improve the sorting performance, the width of the sorting surface of the rocking sorting body is widened or extended backward. However, the selection surface must be widened. However, if the horizontal width of the rocking sorting body is expanded, it will enter the installation area of the grain tanks arranged side by side to reduce the tank capacity, and if it is extended backward, the longitudinal length of the aircraft will become longer and the maneuverability and turning during work will be increased. It reduces the sex.
Therefore, in order to overcome the above problems and meet market demands, the present invention provides a threshing machine having a compact and high-performance machine, while at the same time, a machine for dusts sorted by an oscillating sorting machine. It was created with the intent of not providing anything that allows for comfortable work by eliminating the surging when discharging from the outside.

The threshing process is performed on the handling chamber and the handling products and processed products from the handling chamber and the treatment chamber fall on the swinging sorting body that swings in the left-right direction of the aircraft because the horizontal width is the traveling direction of the aircraft and the sorting surface is widened. , The No. 1 product is sorted by the swinging action and the sorting wind, and the No. 1 product is stored in the grain tanks in which the processing chambers are juxtaposed, and the No. 2 product is returned to the processing chamber and reprocessed. The sorted dust falls from the dust drop port, and the threshed straw is carried backward and processed by the straw processing device.

上がるのを防止するのである。The dust drop port (38) has a longitudinal shape in the front and rear direction and is provided along the traveling direction of the crawler (10), and the dust discharged from the dust drop port (38). The non-grounding of the crawler (10) relatively thinly and evenly falls on the running surface of the crow (10), so that it is surely guided to the ground. Further, the dust drop opening (38) is located inside the outer end portion (10a) of the crawler (10), and the non-grounded surface of the crawler (10) is opposite to the running surface. Therefore, the falling dust is prevented from falling to the outside of the airframe and trampled by the crawler (10) to prevent it from soaring due to the wind.

るのである。As is apparent from the above description, the present invention includes the handling chamber (1) and the processing chamber (3) for processing the material sent from the dust inlet (2) of the handling chamber (1). An oscillating sorting body (4) that is installed in parallel and sorts the unloaded material from the handling chamber (1) and the processed material falling from the processing chamber (3) below the handling chamber (1) and the processing chamber (3).
Is provided so that the axial direction of the handling cylinder (5) and the processing cylinder (6) stored in the handling chamber (1) and the processing chamber (3) is in the same direction as the traveling direction of the machine body, and the swing sorting body ( 4) The swing direction of 4) is made orthogonal to the axial direction, and the dust drop port 38 of the waste sorted by the swing sorting body 4 is not grounded of the crawler 10 constituting the traveling device. The rocking sorting body (4) is characterized in that it is opened on the running surface.
The machine has a compact body with a wide selection surface for high performance, and the dust sorted by the swing sorting body (4) is not grounded by the crawler (10). As it falls on the surface and is guided to the ground and stepped on with the crower (10), the dust drop opening (38) due to the wind
It is possible to perform comfortable work without the dust discharged from the plant rising.
