Description

Technical Field

[0001] This utility model relates to the technical field of organophosphorus detection devices, specifically an organophosphorus residue detection device. Background Technology

[0002] The main reason for testing food for organophosphate residues is to ensure food safety and protect human health. Organophosphate pesticides are widely used as insecticides. Although they can effectively control the number of pests and increase crop yields, their residues pose a potential threat to human health. Therefore, it is necessary to use organophosphate detection devices to test food for organophosphate residues.

[0003] For example, announcement number CN215066165U (named "A Device for Detecting Organophosphorus Pesticide Residues") includes a detection box; a test tube is vertically arranged inside the detection box, and a test tube cap is fixedly placed on the top of the test tube; symmetrical telescopic grooves are opened on the left and right sides of the front side of the detection box, and telescopic rods are slidably inserted into the inner cavities of both sets of telescopic grooves; clamps are fixedly installed at the front ends of both sets of telescopic rods; rubber pads are fixedly adhered to the adjacent sides of the rear sides of both sets of clamps; connecting grooves are opened at the top and bottom of the detection box, and pressure plates and moving plates are slidably inserted into the inner cavities of the two sets of connecting grooves respectively; the top left and right sides of the moving plate are vertically arranged... The device is equipped with a fixed rod and a limiting rod. The top of the fixed rod is rotatably connected to the bottom left side of the pressure plate via a connecting shaft. A limiting block is fixedly installed on the bottom right side of the pressure plate. The left side of the limiting block is connected to the top of the right side of the limiting rod via a slot. Moving the pressure plate and the moving plate in the device allows the test tube to be moved to the center of the mobile phone's camera frame. This allows the device to easily move the position of the test tube relative to the comparison document during actual use, keeping the solution inside the test tube in the center of the mobile phone's camera frame. This makes the device suitable for use with various mobile phone models, effectively improving the convenience of organophosphorus pesticide residue detection.

[0004] The aforementioned organophosphorus detection device requires manual handling of test tubes during use, resulting in low automation and low detection efficiency. Therefore, we provide an organophosphorus residue detection device. Utility Model Content

[0005] The purpose of this invention is to provide an organophosphorus residue detection device to solve the problem mentioned in the background art that existing organophosphorus detection devices require manual handling of test tubes during use, resulting in low automation and low detection efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an organophosphorus residue detection device, comprising a device platform, a bearing support provided at the upper end of the device platform, a central rotating shaft rotatably provided at the upper end of the bearing support, six branch rods welded to the outer wall of the top end of the central rotating shaft, and a valve welded to one end of each of the six branch rods.

[0007] Also includes:

[0008] The bearing seat is located on one side of the bearing support. The bearing seat and the device platform are an integral structure. A perforated frame plate is welded to the upper end of the bearing seat. A bearing plate is welded to one side of the outer wall of the perforated frame plate. A connecting sleeve and a rotating shaft are welded to both ends of the through shaft inside the bearing plate and the perforated frame plate, respectively. An extension shaft is welded to one end of the rotating shaft.

[0009] A reagent cylinder is connected to the upper end of the valve, and six reagent cylinders are provided;

[0010] The liquid preparation tank is magnetically attached to one end of the coupling sleeve, and a placement pool and a liquid pump are provided on one side of the support seat.

[0011] The drive motor is fixed to one side of the outer wall of the support plate by nail-free adhesive, and a vertical rod is welded to the upper end of the extension shaft. A sleeve frame is sleeved on the outside of the vertical rod, and a linkage rod is provided between the sleeve frame and the output shaft of the drive motor.

[0012] Preferably, the inlet and outlet of the liquid pump are both equipped with connecting hoses, and the liquid pump is connected to the placement tank and the liquid preparation tank respectively through the two connecting hoses.

[0013] Preferably, the lower ends of all six valves are connected to a drain pipe, which is connected to the reagent cylinder through the valve.

[0014] Preferably, the top of the liquid preparation tank is equipped with a sealing cap, which is connected to the inside of the liquid preparation tank in a plug-like manner.

[0017] Preferably, seven colorimetric test tubes are placed on the test tube rack at the front end of the support seat.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention uses an eluent to clean the surface of food. The resulting cleaning solution is pumped out and injected into a mixing tank. Then, a reagent cylinder containing suitable test reagents is rotated to the top of the mixing tank, and the valve is opened to discharge the reagents through the drain pipe. The reagents and cleaning solution are then loaded into the mixing tank. A drive motor rotates the linkage rod, which guides the connecting frame along the vertical rod, causing the vertical rod to swing left and right, and simultaneously causing the mixing tank to swing. This ensures that the reagents and cleaning solution are mixed evenly, eliminating manual operation and achieving a high degree of automation. This overcomes the problem of existing organophosphorus detection devices requiring manual handling of test tubes, resulting in low automation and low detection efficiency.
