[0034] When in use, put a vegetable into the upper end of the conveying shell 16 so that the lower end of the vegetable is at the lower end of the conveying shell 16. In the initial state, magnet 1 24 is aligned with magnet 2 25. The magnetism of magnet 1 24 and magnet 2 25 is the same. Magnet 2 25 pushes magnet 1 24 outward, and magnet 1 24 drives the transmission frame 19 to move outward until it is blocked by baffle 22. Turn on the transmission motor 34, and the transmission motor 34 drives the threaded rod 20 to rotate. The threaded rod 20 drives the moving frame 23 to move downward. The moving frame 23 drives the limit rod 21 and the transmission frame 19 to move downward. When the rack 1 29 moves downward to the gear 1 27, the rack 1 29 and the gear 1 2 7 meshes, gear 1 27 drives transmission shaft 32 to rotate, transmission shaft 32 drives pulley shaft 2 79 to rotate, pulley shaft 2 79 drives pulley 2 77 to rotate, pulley 2 77 drives pulley 1 76 to rotate through transmission belt 80, pulley 1 76 drives pulley shaft 1 78 to rotate, pulley shaft 1 78 drives lower belt roller 74 to rotate, belt roller 74 drives conveyor belt 73 to rotate, conveyor belt 73 conveys vegetables downward for a distance, when rack 1 29 disengages from gear 1 27, conveyor belt 73 remains stationary, at this time rack 2 30 and gear 2 28 begin to mesh, gear 2 28 drives gear shaft 31 to rotate, gear shaft 31 drives The driving bevel gear 36 rotates, the driving bevel gear 36 drives the driven bevel gear 37 to rotate, the driven bevel gear 37 drives the linkage shaft 44 to rotate, the linkage shaft 44 drives the two wire reels 45 to rotate, the wire reel 45 winds the pull wire 46, the pull wire 46 pulls the two pull posts 47 to move toward each other, the pull posts 47 drive the two blades 40 to close, and the blades 40 cut the lower end of the vegetables. At this time, magnet 1 24 is aligned with magnet 3 26. Since magnet 1 24 and magnet 3 26 have the same magnetic properties, magnet 1 24 moves inward, and magnet 1 24 drives the transmission frame 19 to move inward. At this time, rack 1 29 and gear 1 27 as well as rack 2 30 and gear 2 28 are not aligned. In the same plane, gear 28 is in a freely rotatable state. Under the action of the return spring 42, the two connecting posts 43 move away from each other, and the two connecting posts 43 drive the two blades 40 to open. The cut vegetables fall into the configuration cylinder, and the transmission motor 34 rotates in the opposite direction. The transmission motor 34 drives the threaded rod 20 to rotate in the opposite direction. The threaded rod 20 drives the moving frame 23 and the transmission frame 19 to move upward and return to the initial state. The magnet 1 24 is aligned with the magnet 2 25. The magnet 2 25 pushes the magnet 1 24 outward. The magnet 1 24 drives the transmission frame 19 to move outward until it is blocked by the baffle 22. Repeat the above operation to complete the segmented cutting of the vegetables. When the transmission motor 34 stops rotating in the reverse direction, the main rotating motor 63 drives the main rotating shaft 64 to rotate, and the main rotating shaft 64 drives the connecting head 65, the connecting plate 66 and the configuration cylinder to rotate an angle. At this time, the configuration cylinder containing vegetables rotates out from the lower side of the conveying shell 16. When the configuration cylinder containing vegetables rotates to the bottom of the crushing assembly 10, the hydraulic cylinder 48 and the crushing motor 49 are started. The hydraulic cylinder 48 drives the crushing motor 49, the crushing rod 50 and the crushing knife 51 to enter the configuration cylinder to crush the vegetables. When the configuration cylinder rotates an angle again, the configuration cylinder containing the crushed vegetables rotates to the liquid distribution assembly 11, when the movable end of the hydraulic cylinder 48 extends downward, the linkage plate 52 moves downward, and the linkage plate 52 drives the movable tube 53 to move downward. When the upper end of the movable tube 53 is below the connection between the connecting tube 57 and the sleeve 56, the extrusion spring 60 presses the sealing piston 61 downward, and the sealing piston 61 pushes the microliter enzyme and color developer mixture into the movable tube 53, enters the connecting cavity 54 through the movable tube 53, and then is sprayed out through the spray hole 62 on the branch pipe 55, while driving the connecting cavity 54 and the branch pipe 55 to rotate, so that the microliter enzyme and color developer mixture is fully mixed with the crushed vegetables; When the main rotating motor 63 drives the main rotating shaft 64 to rotate, the main rotating shaft 64 drives the gear disc 67 to rotate, and the gear disc 67 engages with the rack three 68. After the gear disc 67 rotates an angle, it drives the rack three 68 to move a distance, and the rack three 68 drives the support column 70 and the receiving tube 69 to move a distance, and then the solenoid valve 82 is opened, and the test sample in the configuration tube is filtered through the filter mesh 83 and flows into the receiving tube 69. The test sample enters the detector 15 through the conveying pipe 72, thereby completing the pesticide residue detection in different parts of vegetables.
