本发明涉及农业预冷箱技术领域，特别涉及一种移动式田头太阳能预冷箱。The invention relates to the technical field of agricultural pre-cooling boxes, and in particular to a mobile field solar pre-cooling box.
在农业果蔬种植过程中，农产品成熟后需要采摘，采摘过后需要通过冷藏车运往仓库或者直接发送销售市场，由于冷冻车自重过大，无法下地，一旦下地会造成土地板结，影响土地肥沃程度，因此采摘过程中往往需要小型运输车，将采摘后的农产品运送至冷藏车处，且农产品在从采摘下到进入冷藏车过程中会产生一定损失，为降低从采摘到运输的最初这一过程中农产品的损失，需要用到预冷箱。In the process of agricultural fruit and vegetable planting, agricultural products need to be picked after they are ripe. After picking, they need to be transported to warehouses or directly sent to sales markets by refrigerated trucks. Since the refrigerated trucks are too heavy to go to the ground, once they go to the ground, the soil will become compacted, affecting the fertility of the soil. Therefore, small transport vehicles are often needed during the picking process to transport the picked agricultural products to refrigerated trucks. In addition, there will be certain losses in the process from picking to entering refrigerated trucks. In order to reduce the loss of agricultural products in the initial process from picking to transportation, pre-cooling boxes are needed.
专利号CN110006202A公开的一种产地预冷箱，包括箱体，箱体前侧安装有箱门，箱门表面活动安装有取物门，箱体内部设置有预冷柜，预冷柜上表面中部固定安装有上半导体制冷模组，预冷柜下表面中部固定安装有下半导体制冷模组，箱体内部在预冷柜外围设置有吸热循环管组，箱体上表面开设有安装口，安装口内固定安装有储水箱，吸热循环管组与储水箱连接，该发明虽然能起到一定预冷效果，但是设备结构复杂，且无法在田间地头移动，由于田间地头路面不平整，极易造成农产品磕碰，依旧使得农产品在最初始这一过程中造成损失，因此有必要提出一种新的解决方案。Patent No. CN110006202A discloses a place of origin pre-cooling box, including a box body, a box door installed on the front side of the box body, a retrieval door movably installed on the surface of the box door, a pre-cooling cabinet is arranged inside the box body, an upper semiconductor refrigeration module is fixedly installed in the middle of the upper surface of the pre-cooling cabinet, and a lower semiconductor refrigeration module is fixedly installed in the middle of the lower surface of the pre-cooling cabinet. A heat absorption circulation pipe group is arranged outside the pre-cooling cabinet inside the box body, and an installation port is opened on the upper surface of the box body. A water storage tank is fixedly installed in the installation port, and the heat absorption circulation pipe group is connected to the water storage tank. Although the invention can achieve a certain pre-cooling effect, the equipment structure is complicated and cannot be moved in the fields. Due to the uneven road surface in the fields, it is very easy to cause bumps on agricultural products, which still causes losses to agricultural products in the initial process. Therefore, it is necessary to propose a new solution.
现有的预冷箱只有预冷的效果，但是在田间地头中使用时依旧会 造成农产品损失，且预冷效果差以及节能效果差，为此，我们提出一种移动式田头太阳能预冷箱。The existing pre-cooling box only has the effect of pre-cooling, but it will still cause agricultural product losses when used in the fields, and the pre-cooling effect and energy-saving effect are poor. For this reason, we propose a mobile field solar pre-cooling box.

与现有技术相比，本发明具有如下有益效果：Compared with the prior art, the present invention has the following beneficial effects:
本发明中，通过设置水冷组件以及储物组件，使用过程中，在循环水泵的作用下，水冷箱中的水流经过第三水管进入循环水泵，再从循环水泵经过第二水管进入水冷仓4中，水冷板上部的半导体制冷片上端制冷，通过热传导给水冷仓中的水降温，降温后的水流经过第一水管重新进入水冷箱中，储物箱下部外壁与水冷箱中冷水换热，实现降低储物箱内部温度，实现给刚采摘的农产品降温预冷，保存农产品的质量，通过水浴制冷，使得储物箱内部制冷效果好，且不需要任何制冷剂，能够一直持续工作，不会产生污染源，噪音小，寿命长，方便安装。In the present invention, by arranging a water cooling component and a storage component, during use, under the action of a circulating water pump, the water in the water cooling box passes through the third water pipe into the circulating water pump, and then passes from the circulating water pump into the water cooling bin 4 through the second water pipe. The upper end of the semiconductor refrigeration plate on the upper part of the water cooling plate is refrigerated, and the water in the water cooling bin is cooled by heat conduction. The cooled water flows through the first water pipe and re-enters the water cooling box. The lower outer wall of the storage box exchanges heat with the cold water in the water cooling box, so as to reduce the internal temperature of the storage box, pre-cool the freshly picked agricultural products, and preserve the quality of the agricultural products. The water bath refrigeration has a good refrigeration effect inside the storage box, and does not require any refrigerant, can work continuously, does not generate pollution sources, has low noise, long service life, and is easy to install.
本发明中，通过设置软胶板以及水冷箱内部的水流作用下，设备移动过程中若产生颠簸，储物箱在水冷箱中晃动，储物箱会给软胶板一个作用力，由于软胶板存在一定韧性，使得软胶板给储物箱的反作用力时间增强，在冲量定理的作用线，作用力与反作用力时间变长，进而降低冲击力的大小，起到保护储物箱内部农产品，储物箱晃动的 同时，储物箱会给水冷箱内部水体一个冲击力，由于水体是液态流体，同样会增强冲击力时间，减少冲击力大小，再一次起到防颠簸的作用，进一步保护储物箱内部的农产品，当设备移动到冷藏车前，打开箱门，卸下储物箱内部的农产品，使得农产片在采摘运输的初期得到很好的保护，减少农产品损失，提高经济效益。In the present invention, by setting a soft rubber plate and the water flow inside the water cooling box, if bumps occur during the movement of the equipment, the storage box shakes in the water cooling box, and the storage box will give a force to the soft rubber plate. Since the soft rubber plate has a certain toughness, the reaction force time of the soft rubber plate on the storage box is enhanced. On the action line of the impulse theorem, the action force and reaction force time become longer, thereby reducing the size of the impact force, thereby protecting the agricultural products inside the storage box. At the same time as the storage box shakes, the storage box will give an impact force to the water body inside the water cooling box. Since the water body is a liquid fluid, the impact force time will also be enhanced and the impact force size will be reduced, once again playing an anti-bumping role, further protecting the agricultural products inside the storage box, when the equipment moves to the front of the refrigerated truck, the box door is opened, and the agricultural products inside the storage box are unloaded, so that the agricultural products are well protected in the early stage of picking and transportation, reducing the loss of agricultural products and improving economic benefits.

The present invention is a mobile field solar pre-cooling box. First, it is connected to the external water source pipeline through the water adding pipe 30, the valve 31 is opened, and a proper amount of liquid water is added to the water cooling box 2, and the valve 31 is closed. When the equipment is working in the field, the U-shaped handle 25 is used to cooperate with the drawer slide 13 to pull out the solar panel 11, and the solar panel 11 is used to cooperate with the solar controller in the control box 12 to realize the conversion of solar energy into electrical energy, and finally the electrical energy is stored in the battery in the control box 12. When in use, the drive motor 22 is started, and the drive motor 22 drives the first pulley 23 to rotate, and the first pulley 23 drives the second pulley 24 to rotate through the transmission belt, and the second pulley 24 The rotating shaft 20 is driven to rotate, and the rotating shaft 20 drives the driving wheel 21 to rotate, so as to drive the equipment to move. The steering wheel 18 is used to realize the equipment, and the circulating water pump 7 is started. The water in the water cooling box 2 enters the circulating water pump 7 through the third water pipe 8, and then enters the water cooling warehouse 4 from the circulating water pump 7 through the second water pipe 6. The upper end of the semiconductor refrigeration plate 10 on the upper part of the water cooling plate 9 is refrigerated, and the water in the water cooling warehouse 4 is cooled by heat conduction. The cooled water flows through the first water pipe 5 and re-enters the water cooling box 2. The box door 16 is opened, and the freshly picked agricultural products are placed in the storage box 15. The lower outer wall of the storage box 15 exchanges heat with the cold water in the water cooling box 2, so as to reduce the internal temperature of the storage box 15, and realize the pre-cooling of the freshly picked agricultural products, preserve the quality of the agricultural products, and reduce the high temperature caused by To prevent the loss of agricultural products, the storage box 15 is filled with the door 16, and the slider 34 is slid. The slider 34 drives the lower end of the C-shaped bar 35 to enter the ring 33 to fix the door 16. The use of the heat insulation board 17 prevents the external high temperature from exchanging heat with the storage box 15 with a lower temperature, and ensures the low temperature environment inside the storage box 15. The equipment moves in the field under the drive of the driving wheel 21. Due to the uneven road surface in the field, it will be bumpy. If bumps occur, the storage box 15 will shake in the water cooling box 2. In order to reduce the loss of agricultural products inside the storage box 15 caused by the shaking of the storage box 15, the storage box 15 will exert a force on the soft rubber board 14. Since the soft rubber board 14 has a certain toughness , which increases the reaction time of the soft rubber plate 14 on the storage box 15. On the line of action of the impulse theorem, the time of the action force and the reaction force becomes longer, thereby reducing the magnitude of the impact force, thereby protecting the agricultural products inside the storage box 15. When the storage box 15 shakes, it will give an impact force to the water body inside the water cooling box 2. Since the water body is a liquid fluid, it will also increase the impact time and reduce the magnitude of the impact force, once again playing an anti-bumping role, further protecting the agricultural products inside the storage box 15. When the equipment is moved to the front of the refrigerated truck, the box door 16 is opened, and the agricultural products inside the storage box 15 are unloaded, so that the agricultural products are well protected in the early stage of picking and transportation, reducing the loss of agricultural products.
