[0025] Example 1
[0026] The present application discloses an agricultural product laboratory testing device. Unlike the existing device, which requires placing equal amounts of water and agricultural products in the same device and manually stirring the water flow to dissolve the pesticides remaining on the surface of the agricultural products into the water flow, the present application weighs the agricultural products put into the cleaning box 1 to determine the volume of water that needs to flow into the cleaning box 1, thereby ensuring that the agricultural products and water are in a specified ratio, without the need for manual testing and placement, reducing the workload of the staff and improving the working efficiency of the device;
[0027] Reference Figures 1 to 7 As shown, the cleaning box 1 is a rectangular cavity with an opening at the top, and a support plate 2 is slidably connected inside the cleaning box 1. The outer wall of the support plate 2 is slidably connected to the inner wall of the cleaning box 1, and the size of the support plate 2 is the same as the internal space of the cleaning box 1. A sealing rubber is provided on the outer wall of the support plate 2 to ensure that there is a good seal between the support plate 2 and the cleaning box 1 to prevent water from flowing out of the gap between the cleaning box 1 and the support plate 2. A support frame 14 is connected to the bottom end of the cleaning box 1, and a buffer portion 15 is provided at the bottom end of the support frame 14. A support rod 23 is provided at the bottom end of the support plate 2, and the support rod 23 passes through the cleaning box 1 and is slidably connected in the support frame 14. The support frame 14 The bottom end of the support plate 2 is slidably connected to the buffer portion 15, and drainage holes 22 are symmetrically arranged at both ends of the support plate 2. The top of the drainage hole 22 is provided with an inwardly curved arc, so that the water flow around the drainage hole 22 can smoothly flow into the drainage hole 22. The bottom end of the drainage hole 22 is connected to a water delivery pipe 26, which passes through the cleaning box 1. The bottom end of the water delivery pipe 26 is provided with a water valve for controlling the outflow of liquid. The top of the support plate 2 is provided with a water guide platform 21. The liquid injected into the support plate 2 will be accumulated on the two ends of the support plate 2 through the guidance of the water guide platform 21, thereby ensuring that the liquid can flow into the corresponding drainage hole 22 to reduce the residual liquid on the support plate 2;
[0028] Water injection components are symmetrically arranged at both ends of the cleaning box 1. The water injection components are used to inject water in proportion to the agricultural products put into the cleaning box 1, so as to reduce the workload and work errors of workers' manual addition. The water injection component includes a water tank 11 for storing clean water. The water tank 11 is fixedly connected to one end of the cleaning box 1. A plurality of drainage holes 13 are arranged on the end of the water tank 11 facing the cleaning box 1. The drainage holes 13 are used to allow the water in the water tank 11 to flow out and flow into the cleaning box 1. A limiting chute 12 is arranged at the other end of the water tank 11. A limiting rod 31 is slidably connected to the limiting chute 12. A connecting rod 3 is arranged at the bottom end of the limiting rod 31. The connecting rod 3 is connected to the lower half of the water supply pipe 26. When the water supply pipe 26 moves up and down, the connecting rod 3 is driven to move in the same direction. A front baffle plate 32 is connected to the top of the limiting rod 31. One end of the front baffle plate 32 is fitted with the water tank 11. A drainage pipe 33 is fixed and connected to the front baffle plate 32. The end of the drainage pipe 33 contacts the water tank 11 A guide pipe is provided, and the guide pipe is made of rubber or other elastic materials. When the drain pipe 33 is connected to one of the drain holes 13, the guide pipe is inserted into the connected drain hole 13 to ensure that the water in the water tank 11 can flow into the drain pipe 33 from the drain hole 13 and flow into the cleaning box 1 through the guidance of the drain pipe 33. A plurality of blocking balls 34 are provided on the end of the front baffle 32 that is in contact with the water tank 11. The blocking balls 34 are made of rubber material. When the blocking balls 34 are connected to the drain holes 13, the blocking balls 34 block the connected drain holes 13 to ensure that the water in the water tank 11 can only flow out from the drain pipe 33, thereby ensuring that the total amount of water injected into the cleaning box 1 is proportional. When the support plate 2 moves downward, the drain pipe 33 is driven to move downward, so that the liquid in the water tank 11 located at the upper end and nearby of the drain pipe 33 flows into the cleaning box 1 through the drain pipe 33, and the liquid located at the lower end of the drain pipe 33 stays in the water tank 11 for subsequent detection.
[0029] Example 2
[0030] Based on Example 1, Figures 1 to 7 As shown, a plurality of positioning holes 25 are arranged at equal intervals on the support rod 23, and a through hole is arranged on the buffer portion 15. When the through hole coincides with one of the positioning holes 25, a bolt is passed through the through hole and threadedly connected with the positioning hole 25, thereby locking the support rod 23 to prevent the pressure on the support plate 2 from increasing after the water flow is injected, thereby preventing the support plate 2 from sliding down and causing the water injection amount to change;
[0031] A tension spring is sleeved on the support rod 23, and the support plate 2 is buffered by the tension spring, thereby ensuring that the support plate 2 maintains a certain height when no agricultural products are placed, and slowly descends after the agricultural products are placed, so as to facilitate the staff to position and lock.
[0032] Example 3
[0033] Based on Example 2, Figures 1 to 7 As shown, a vibration part 16 is provided on the support frame 14, and a vibration disk 41 is rotatably connected inside the vibration part 16. The vibration disk 41 is an eccentric wheel disk, and the axis of the eccentric shaft of the vibration disk 41 is colinear with the center line of the vibration part 16. The vibration disk 41 rotates along the center line of the vibration part 16, and buffer balls 17 are symmetrically provided at both ends of the vibration part 16. During the rotation of the vibration disk 41, the front end of the vibration disk 41 will collide with the contacting buffer balls 17, thereby driving the water flow in the cleaning box 1 to vibrate, thereby realizing the function of stirring the water flow instead of the staff. The bottom end of the vibration part 16 is connected to the motor 4, and the output shaft of the motor 4 is connected to the vibration disk 41 to provide power for the rotation of the vibration disk 41.
