[0035] Through the sealing mechanism 2 arranged at the top end of the sampling tank 1, the sampling tank 1 can be sealed, thereby avoiding the situation that the samples stored inside the sampling tank 1 fall out and come into contact with the outside world, which may affect the detection accuracy. At the same time, through the cold storage box 3 rotatably installed at the bottom end of the sampling tank 1, the cold storage agent can be added according to requirements, thereby cooling the inside of the sampling tank 1, so that the agricultural products stored inside the sampling tank 1 are in a low-temperature storage state, avoiding the situation that the agricultural products rot in the sampling tank 1 due to too high temperature, which may affect the detection.

Through the vacuum heat insulation cavity 9 provided inside the sampling tank 1, the principle of using vacuum to block temperature can be utilized to improve the heat insulation effect inside the sampling tank 1 and avoid the influence of the external temperature on the inside of the sampling tank 1, thus preventing the situation that the agricultural products stored inside change and affect the detection.

[0037] As Figures 3 to 4 shown, a connection hole 12 is provided at the top end of the first positioning post 4. A roller bearing 13 is fixedly connected inside the connection hole 12. The sealing mechanism 2 includes a sealing cover 14 fixedly connected to the top end of the roller bearing 13. The other end of the sealing cover 14 is fixedly connected to a buckle frame 15. The buckle frame 15 is located at the top end of the second positioning post 5. Connecting threaded rods 16 are installed inside the cold storage box 3 and the first positioning post 4 through threaded grooves in a meshing manner. Adjusting rollers 17 are installed inside the cold storage box 3 and the first positioning post 4 through rotating shafts. The adjusting rollers 17 are threadedly engaged with the outer wall of the connecting threaded rod 16. A positioning groove 18 is provided at the top end of the second positioning post 5. A clamping convex block 19 is fixedly connected inside the positioning groove 18. A clamping groove 20 is provided on one side of the buckle frame 15. The clamping convex block 19 and the clamping groove 20 match each other. An elastic pressing plate 21 is fixedly connected to the inner wall of the clamping groove 20. Connecting screw holes are provided in the clamping convex block 19 and at the top end of the roller bearing 13, and the size of the connecting screw holes matches that of the connecting threaded rod 16. Through the roller bearing 13 fixedly connected inside the connection hole 12, it is convenient to rotate the sealing cover 14, thus completing the opening and closing of the sampling tank 1. When the buckle frame 15 moves to the top end of the second positioning post 5, the clamping groove 20 provided on one side of the buckle frame 15 will wrap the clamping convex block 19 fixedly connected inside the positioning groove 18. At the same time, the elastic pressing plate 21 fixedly connected to the inner wall of the clamping groove 20 will squeeze the buckle frame 15 to limit the buckle frame 15 and complete the closing operation of the sealing cover 14. By rotating the adjusting roller 17, the connecting threaded rod 16 can be driven to rotate, so that the connecting threaded rod 16 rotates and moves downward. The connecting threaded rod 16 can be inserted into the connecting screw holes at the top of the clamping convex block 19 and the top end of the roller bearing 13 of the same structure sampling box to meet the requirement of splicing and using the same sampling box.

[0038] AsFigure 1 and Figure 5 As shown in Figure 1 and Figure 5 , a storage groove 22 is provided at the top end of the sealing cover 14. A lifting handle 23 is installed inside the storage groove 22 through a hinge. By pulling out the lifting handle 23 installed inside the storage groove 22 at the top end of the sealing cover 14, the entire sampling can 1 can be lifted and carried. Moreover, the provided storage groove 22 can be used to store and hide the lifting handle 23, avoiding the influence of the lifting handle 23 on the splicing operation of the sampling can 1 when the same sampling cans 1 are stacked and combined for use.

[0039] As Figure 1 and Figure 2 shown in Figure 1 and Figure 2 , a label groove 24 is provided on the outer wall of the sampling can 1. A sealing diaphragm is installed inside the label groove 24 by snap fit. The label groove 24 provided on the outer wall of the sampling can 1 can be used to place labels recording agricultural product information. Moreover, the sealing diaphragm installed inside the label groove 24 by snap fit can cover and protect the labels.

[0040] As Figure 3 shown in Figure 3 , an air release groove 10 is provided at the bottom end of the cold storage box 3. The cold storage box 3 is made of heat-insulating material. Through the air release groove 10 provided at the bottom end of the cold storage box 3, it can be avoided that when the same sampling cans 1 are spliced and used, a vacuum negative pressure is generated between the sampling cans 1, resulting in inconvenient separation. Moreover, the opening of the air release groove 10 can also enhance the friction force at the bottom end of the cold storage box 3, thus playing an anti-slip function. The cold storage box 3 made of heat-insulating material can avoid the rapid loss of the internal temperature and also prevent the external temperature from being transmitted into the cold storage box 3 and affecting the use effect of the refrigerant inside.

[0041] As Figure 4 and Figure 5 shown in Figure 4 and Figure 5 , the sealing cover 14 is made of a hollow plastic plate, and a sealing rubber ring is fixed at the bottom end of the sealing cover 14. The sealing cover 14 made of a hollow plastic plate has a good heat insulation effect, low cost, and is convenient to replace. Moreover, the sealing rubber ring fixed at the bottom end of the sealing cover 14 can seal the gap between the bottom end of the sealing cover 14 and the internal storage cavity 6 of the sampling can 1.

[0042] The working principle of the utility model is as follows: the collected agricultural products are placed into the inner box 7 inside the sampling tank 1, and then the sealing cover 14 is moved to move the snap frame 15 at one end of the sealing cover 14 to the top of the No. 2 positioning column 5, and snap into the outer wall of the snapping protrusion 19 at the top of the No. 2 positioning column 5, and the elastic pressure plate 21 fixedly connected to the inner wall of the snapping groove 20 on one side of the snap frame 15 is used to squeeze the snapping protrusion 19 to complete the limiting operation of the snap frame 15, thereby completing the sealing operation of the sealing cover 14 on the sampling tank 1. When multiple agricultural products need to be spliced ​​together in the sampling tank 1, two identical sampling tanks 1 are aligned and stacked, and the rotating adjustment roller 17 drives the connecting threaded rod 16 to rotate, so that the connecting threaded rod 16 rotates and moves downward, and the connecting threaded rod 16 can be inserted into the connecting screw holes opened by the snapping protrusions 19 at the tops of the No. 1 positioning column 4 and the No. 2 positioning column 5 on both sides of the sampling tank 1 with the same structure and the roller bearing 13. The connecting threaded rod 16 is used to complete the splicing and combination of the identical sampling tanks 1, so that the entire sampling box is square. The sampling tank 1 is portable and can be used in combination with other sampling tanks 1 by rotating the adjusting roller 17 on the outer wall of the second positioning column 5 to adjust the connecting threaded rod 16 in the second positioning column 5 so that the connecting threaded rod 16 is disengaged from the connecting screw hole at the top of the clamping protrusion 19. The sampling tank 1 can be rotated separately to adjust the position of the sampling tank 1 to complete the operation of taking and placing agricultural products inside the single sampling tank 1. According to the collected agricultural product information, the collected information can be made into a label and put into the label slot 24 provided on the outer wall of the sampling tank 1. When the collected agricultural products need to be refrigerated and stored, the sealing plugs 11 rotatably installed on both sides of the cold storage box 3 can be rotated to inject the cold storage agent into the cold storage box 3 through the hole to cool the inside of the sampling tank 1 to meet the refrigeration requirements of the agricultural products. After completing the operation of collecting and storing agricultural products, the inner box 7 can be taken out by rotating the inner box 7, and the inner box 7 can be cleaned and disinfected separately to avoid the situation where the residual debris inside the inner box 7 affects the storage of agricultural products next time.
