Description

Technical Field

[0001] The invention relates to the technical field of agricultural pre-cooling boxes, and in particular to a mobile field solar pre-cooling box. Background Art

[0002] 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.

[0003] 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.

[0004] The existing pre-cooling box only has a pre-cooling effect, 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. Summary of the invention

[0005] The main purpose of the present invention is to provide a mobile field solar pre-cooling box, which can effectively solve the problems of large agricultural product losses, poor pre-cooling effect and poor energy-saving effect in the background technology.

Entering the water cooling bin, the lower wall of the water cooling bin adopts a 0.02cm thick stainless steel plate, so that the water cooling bin made of stainless steel plate has a good heat conduction effect, which is convenient for the water cooling plate to cool the water in the water cooling bin. The cooled water flows through the first water pipe and re-enters the water cooling box. The semiconductor refrigeration plate adopts the Peltier effect electrical element. The principle is that when the thermocouple formed between different semiconductor materials passes through the current, heat transfer will occur at both ends. The heat will move from one end to the other end, so a temperature difference will appear to form the required cooling end. By using the semiconductor refrigeration plate, no refrigerant is required, it can work continuously, no rotating parts are required, no pollution source will be generated, and there will be no rotation effect.

Due to the action of the circulating water pump, the water in the water cooling box always flows out from the first water pipe on one side, and then flows into the third water pipe on the other side. Therefore, the water always flows in the same direction in the water cooling box. By providing the flow stabilizing plate and the flow stabilizing holes, the water flow in the upper part of the water cooling box is relatively stable, thereby ensuring that no thrust caused by the flow of water is generated around the lower part of the storage box.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 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.

It can work continuously, will not generate pollution sources, has low noise, long service life, and is easy to install.

[0019] 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. While the storage box is shaking, 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.

[0044] The working principle of the present invention is: please refer to Figure 1-9As shown, the present invention is a mobile field solar pre-cooling box, which is first connected to the external water source pipeline through the water adding pipe 30, and the valve 31 is opened to add a proper amount of liquid water into 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 rail 13 to pull out the solar panel 11, and the solar panel 11 cooperates 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 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 cooling and preheating of the freshly picked agricultural products.

The equipment is driven by the driving wheel 21 and moves in the field. Due to the uneven road surface in the field, bumps will occur. 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. Due to the soft rubber board 14 has a certain toughness, so that the reaction time of the soft rubber plate 14 on the storage box 15 is enhanced. 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 enhance the impact time and reduce the impact force. Once again, it plays 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.
