The first door body 310 movably covers the second liquid inlet, and the second door body 320 movably covers the second liquid outlet.

[0026] Specifically, it further includes a controller (not shown in the figure) and a motor (not shown in the figure). The motor is used to drive the conveyor belt 200, and both the circulation pump 400 and the motor are electrically connected to the controller. The controller and the motor are both arranged on the frame 100. That is to say, the controller controls the circulation pump 400 and the motor through a computer program. Further, driven by the motor, the conveyor belt 200 can rotate. It is worth mentioning that the cross-sectional shape of the conveyor belt 200 is oval. Through the rotation of the conveyor belt 200, the staff can put different agricultural products into different placement baskets 500. By controlling the controller to turn on the circulation pump 400, the coolant in the cooling pipe 600 can circulate simultaneously with the coolant in the liquid storage tank 300. That is to say, through the contact between the cooling pipe 600 and the conveyor belt 200, the heat on the conveyor belt 200 is transferred to the cooling pipe 600, and then the heat on the cooling pipe 600 is taken away from the inside of the cooling pipe 600 by the coolant. That is to say, through continuous circulation, the heat on the conveyor belt 200 is transferred to the liquid storage tank 300, and then through the circulation pump 400, the coolant continuously flows into the cooling pipe 600. It can well maintain that the agricultural products keep an appropriate temperature during the transportation process, and can well avoid the problem that the quality of the agricultural products is affected due to the certain temperature of the conveyor belt 200 during the transportation process.

[0027] In the above embodiment, when replacing the coolant in the liquid storage tank 300, by opening the second door body 320, the coolant flows out from the second liquid outlet, and then after all the coolant in the liquid storage tank 300 has flowed out, close the second door body 320, and then open the first door body 310, and add new coolant into the liquid storage tank 300 from the second liquid inlet. It is worth mentioning that both the first door body 310 and the second door body 320 are hinged to the outer surface of the liquid storage tank 300, and sealing rings are provided on both the first door body 310 and the second door body 320. By using the sealing rings, it can well prevent the coolant from leaking out.

[0028] In one embodiment, labels (not shown in the figure) are provided on several of the placement baskets 500. That is to say, labels are provided on the outer side surface of the placement basket 500. Specifically, the label is a whiteboard, that is, the name of the corresponding agricultural product in the placement basket 500 can be directly written on the whiteboard, which is convenient to directly identify the agricultural product placed in the placement basket 500 through the label. It is worth mentioning that the writing on the whiteboard can be wiped, that is to say, it can be changed multiple times on the label.

[0029] In the above embodiments, each of the placement baskets 500 is provided with a sliding door 510, and each of the placement baskets 500 is provided with an opening. Specifically, the label is arranged on the outer side of the sliding door 510. Further, two corresponding slide rails (not shown in the figure) are arranged on each placement basket 500, and the left and right sides of the sliding door 510 are respectively connected to a slide rail, so that the sliding door 510 can slide up and down, and an opening is provided at one end of the placement basket 500 away from the conveyor belt 200. That is to say, agricultural products can be directly put into the placement basket 500 from the opening. When taking out the agricultural products, they can be taken out from the opening, or the sliding door 510 can be pushed upward, and then the agricultural products in the placement basket 500 can be taken out.

[0030] In one embodiment, the cross-sectional shape of the cooling pipe 600 is wavy. Specifically, by designing the cooling pipe 600 into a wavy shape, and a part of the cooling pipe 600 is arranged on the workbench 110, the wavy shape enables the cooling pipe 600 to have a larger contact area with the conveyor belt 200, thereby better dissipating heat from the conveyor belt 200, so that the heat on the conveyor belt 200 is transferred to the cooling pipe 600, and then the heat on the cooling pipe 600 is taken away by the coolant from the inside of the cooling pipe 600. Through continuous circulation, the heat on the conveyor belt 200 is transferred to the liquid storage tank 300, and then through the circulation pump 400, the coolant continuously flows into the cooling pipe 600. It can well maintain that the agricultural products are at a suitable temperature during the transportation process, and can well avoid the problem that the quality of the agricultural products is affected due to the fact that the conveyor belt 200 has a certain temperature during the transportation process.

[0031] In one embodiment, the second liquid inlet is opened at one end of the liquid storage tank 300 close to the workbench 110, and the second liquid outlet is opened at one end of the liquid storage tank 300 away from the workbench 110. Specifically, the second liquid inlet is located above the second liquid outlet, and the second liquid outlet is located at the edge of the side of the liquid storage tank 300 close to the bottom.
