By adding a crushing shaft, preliminary crushing of the food entering the crushing box is achieved. By adding a rotating disc and an adjusting plate, when the rotating disc rotates, the adjusting plate is driven to adjust its position through a rotating shaft. The adjusting plate drives the fixing plate and the sliding plate to adjust their positions through the rotating shaft, and the sliding plate drives the support plate and the water-passing cylinder to perform reciprocating height adjustment processing, and the pesticide residues on the food are separated and extracted by the pesticide extraction solution.

[0010] By adopting the foregoing technical solutions, the beneficial effects of the present utility model are as follows: The pesticide residue detection sampling device for the preparation of aquatic products of the present utility model improves the situation that the existing technology still has the problem of only being able to extract one of the tissue fluid or the soaking solution during actual use, and the detection accuracy is not high. During use, first add the sample into the sample chamber, add the solvent, cover the lid, use ultrasonic waves to act on the pesticides adhered to the surface of the sample, so that the pesticides on the surface are dissolved in the solvent, and then the solution flows into the sampling box for storage. Then add the solvent again, start the rotating cutter to break and grind the sample, and then the solution flows into another sample box for storage. It can be automatically filtered in the sample box, and can be quickly detected after reaching the laboratory. It can detect the pesticide residues in the tissue fluid or the soaking solution on the same sample at the same time, improving the detection accuracy and the convenience of use.
