Description

Technical Field

[0001] The utility model relates to the technical field of pesticide residue detection, in particular to an agricultural product detection pretreatment device. Background Art

[0002] Agricultural products are items produced in agriculture, such as rice, sorghum, peanuts, corn, fruits and vegetables, and local specialties from various regions. Agricultural products need to undergo pesticide residue testing before they are sold, and can only be sold after passing the test. Pesticide residue refers to the phenomenon that some pesticides remain directly or indirectly in grains, vegetables, fruits and soil after pesticides are applied in agricultural production. Since pesticide residues can pose a threat to people's health, pesticide residues have become a widely concerned issue, and people also have high requirements for the detection of pesticide residues.

The above-mentioned problem still exists. Before the pesticide residue determination of agricultural products, it is necessary to place the agricultural products in a reagent tube and add an extraction solvent to perform shaking, homogenization and other operations. After standing for a period of time, the pesticide residue detection and analysis can be performed on them. The above-mentioned device can mix the solvents in multiple reagent tubes by setting a stirring blade. When multiple batches of samples need to be mixed at one time, the stirring blade is easily contaminated with the sample from the previous mixing, which is easy to affect the accuracy of subsequent sample detection, and is not convenient for contactless mixing of samples. After a batch of samples is mixed, it is necessary to take them out first, then put in new samples, and then perform mixing work.
