[0025] according to Figure 1-7This embodiment provides a pesticide residue detection device for vegetables, including a workbench 1. The workbench 1 is equipped with a conveying device 2, a housing 3, and a support 4. The conveying device 2 is a belt conveyor. A cutting assembly 11 is provided on the workbench 1, located at the output end of the conveying device 2. The cutting assembly 11 includes a motor 111, which is fixedly mounted on the housing 3. A rotating shaft 112 is fixedly mounted at the output end of the motor 111 and rotatably connected to the housing 3. Multiple blades 113 are fixedly mounted on the rotating shaft 112. These blades 113 are used to cut vegetables of different widths. When the diameter of the transported vegetable is small, only one blade is used for cutting; when the diameter of the transported vegetable is large, multiple blades are used for cutting. A clamping assembly 12 is provided on the workbench 1. The clamping assembly 12 includes a bidirectional synchronous cylinder 121 and two symmetrically arranged conveying devices 122, which are belt conveyors. A step cylinder 121 is slidably connected to the housing 3. Two conveying devices 122 are rotatably mounted on the workbench 1. When cutting vegetables of different shapes, the two conveying devices 122 will open to facilitate passage. The output end of the bidirectional synchronous cylinder 121 is hinged to the two conveying devices 122 respectively, so that the two conveying devices 122 are reset by the bidirectional synchronous cylinder 121 after opening. A detection barrel 41 is movably mounted on the bracket 4. An electric push rod 42 is fixedly mounted on the workbench 1. The output end of the electric push rod 42 is fixedly connected to the detection barrel 41. A reagent box 43 is fixedly mounted on the bracket 4. The detection barrel 41 and the reagent box 43 are set together. When the cut vegetables fall into the detection barrel 41, the extract in the reagent box 43 is pumped into the detection barrel 41. The electric push rod 42 drives the detection barrel 41 to reciprocate, which facilitates the full reaction of the reagent solution with pesticide residues. A detector 44 is set below the detection barrel 41. After the reaction is full, the residue flows into the detector 44.

[0026] A cleaning tank 13 is fixedly installed on the workbench 1, and a pump 131 is fixedly installed on the cleaning tank 13. A spray head 132 is fixedly installed at the output end of the pump 131. The spray head 132 is used to clean the test tank 41 with the cleaning liquid in the cleaning tank 13.

[0027] The bracket 4 is provided with a mounting frame 45, and a second pump 46 is fixedly mounted on the mounting frame 45. The input end of the second pump 46 is connected to the reagent box 43, and the output end of the second pump 46 is fixedly mounted with a bellows 461. The bellows 461 is configured to cooperate with the detection container 41. The continuous movement of the detection container 41, through the flexibility and extensibility of the bellows 461, allows the detection container 41 to add reagent solution during the movement.

[0028] The detection barrel 41 is equipped with a sieve cylinder 411, which is snapped into the detection barrel 41 for easy disassembly. The detection barrel 41 is equipped with a splash-proof dropper 412, and a solenoid valve 413 is installed on the splash-proof dropper 412. The splash-proof dropper 412 is set to prevent the solution from splashing during titration, and the solenoid valve 413 is set to facilitate the control of the reaction time.

[0029] Multiple telescopic rods 47 are fixedly installed on the bracket 4. The output end of the telescopic rod 47 is fixedly connected to the detection barrel 41. The multiple telescopic rods 47 are distributed in a circumferential shape along the detection barrel 41. The detection barrel 41 is provided with a flange. By connecting the telescopic rods 47 to the flange, the detection barrel 41 can be buffered when vibrating, preventing damage to the detection barrel.

[0030] The second conveying device 122 includes a conveyor belt 123, on which multiple friction strips 124 are fixedly installed to facilitate the conveying of round vegetables to one side.

[0031] The specific operation is as follows: The vegetables are placed on the conveyor device 122 and transported in the direction of transport. The position of the vegetables is corrected by the conveyor device 222. At the same time, the friction strip 124 contacts the vegetables to facilitate dynamic fixation of the vegetables. The vegetables are cut by the blade 131 and fall into the detection bucket 41. The reagent solution in the reagent tank 43 is pumped into the detection bucket 41 by the pump 22. The electric push rod 42 is started to drive the detection bucket 41 to move, so that the reagent solution can react with the pesticide residue on the vegetables. After the reaction is complete, the solenoid valve 413 is opened and the reacted solution is dripped into the detector 44 through the anti-splash drip head 412 to check the amount of pesticide residue on the vegetables. After the test is completed, the vegetables in the detection bucket 41 are cleaned out. The pump 131 is turned on and the cleaning solution in the cleaning tank 13 is sprayed onto the detection bucket through the spray head 132.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
