[0001] The utility model relates to the technical field of pesticide residue detection, in particular to a sample crushing device for detecting pesticide residues in agricultural products. Background Art

[0002] Through rapid and accurate detection of pesticide residues in agricultural products, we can timely discover and prevent foods containing excessive pesticide residues from entering the market, effectively protecting the health rights and interests of consumers. When sampling and testing agricultural products, they need to be crushed and then the puree ingredients need to be tested.

[0003] After searching, the announcement number is CN212904123U, and the name is a rapid sample crushing device for agricultural product pesticide residue detection, including a processing chamber. Through research and analysis, it was found that although it has the advantages of good sample crushing effect and high crushing efficiency through preliminary extrusion crushing and secondary cutting crushing during use, it still has the following disadvantages to a certain extent.

[0004] For example, it does not have a cleaning function. During the use of the above device, after the sample is crushed, the inner wall of the box cannot be automatically rinsed, causing part of the fruit puree to easily adhere to the inner wall of the box, making it difficult to clean the dirt. It also does not have a solid-liquid separation function and cannot separate the fruit puree and juice, which in turn affects subsequent testing operations. In order to solve the above technical problems, we have designed a sample crushing device for agricultural product pesticide residue detection. Utility Model Content
