[0017] The present invention provides a pesticide residue detection device for food safety detection. It has the following beneficial effects:

[0018] 1. The pesticide residue detection equipment for food safety detection adopts a composite mechanism design. The reagent tube is placed inside the frame cutout of the rotating frame, and the test tube is clamped by a fixing mechanism to improve the stability of the test tube, avoid shaking during rotation, and prevent leakage of the detection liquid. The circular groove is sealed by a protective component to prevent external impurities from interfering with the interior and reduce safety hazards. The sampled liquid is then introduced into the test tube through the protective component, and the first motor is started to drive the rotating frame to rotate on the surface of the annular frame through the central rotating shaft, thereby achieving the effect of rotary centrifugation. After centrifugation, the pesticides dispersed in the water can be gathered, so that the pesticide concentration is relatively increased during subsequent detection, which is more conducive to accurately detecting low-concentration pesticide residues and improving the detection sensitivity. The sample inside the test tube is then detected by a spectrometer.

[0019] 2.

The friction column is made of plastic material to reduce the wear on the test tube surface. By opening a cylindrical groove and increasing the contact area through the grooving, a certain anti-slip effect is achieved, further improving the braking effect.

[0020] 3. The pesticide residue detection equipment for food safety testing, through the protection component design, controls the acrylic cover to be lifted by the first electric push rod, so as to facilitate the placement of the test tube into the equipment. At the same time, the acrylic cover is controlled to be lowered by the first electric push rod to seal the test tube, reduce the pollution of impurities in the external environment, and improve the accuracy of the detection. At the same time, it plays a shielding role, reduces manual operation, avoids the contact of pesticide residue liquid with the human body, reduces safety hazards, and moves the liquid from the supporting pipe to the injection mechanism through the processing mechanism, and injects it into the test tube through the injection mechanism, thereby improving the working efficiency.

[0021] 4. The pesticide residue detection equipment for food safety detection places the food particles and the diluent for detection into the processing shell through the processing mechanism design, and then places the processing cover plate on the top of the processing shell, so that the connecting shaft is inserted into the friction mechanism, and the second motor drives the connecting shaft to rotate to rotate the stirring mechanism, thereby promoting the mixing of food particles and diluent, promoting the dissolution of pesticide residues, accelerating the reaction speed, and improving the working efficiency. At the same time, the friction mechanism is driven to rub the inner wall of the equipment to reduce the adhesion of food particles, facilitate subsequent cleaning, and prevent material retention from causing pollution to the equipment. After the food particles are mixed with the diluent, the particles are filtered through the infiltration plate, which has a barrier effect on the particles and promotes the liquid to flow to the bottom. Then, the liquid is allowed to flow to the inside of the composite mechanism through the supporting pipe through the output mechanism, which is convenient for subsequent detection.

[0022] 5. The pesticide residue detection equipment for food safety testing, through the output mechanism design, guides the liquid through the funnel tube to promote liquid flow and reduce liquid residue. The liquid flow is controlled by the electric control valve to increase the operating time of the equipment, so that the material and liquid are fully and evenly mixed, and the detection accuracy is improved. The liquid passes through the output pipe when it flows downward. The spiral plate adopts a spiral structure. The spiral structure improves the liquid mixing effect and evenly distributes the internal components. The spiral structure slows down the liquid flow speed to prevent the liquid flow from being blocked and affecting the equipment operation. The liquid enters the inside of the carrier tube and plays the role of transition liquid, thereby promoting the uniform flow of the liquid. BRIEF DESCRIPTION OF THE DRAWINGS
