Description

Technical Field

[0001] The utility model relates to the technical field of pesticide residue sampling, in particular to a pesticide residue sampling device. Background Art

[0002] During the growth process of crops, pesticides need to be sprayed to prevent pests. After spraying pesticides on crops, some pesticides will not be decomposed and remain on the crops. These pesticides contain trace amounts of pesticide precursors, toxic metabolites, degradation products, impurities and other harmful substances, which will harm the crops after a period of time. In order to detect the amount of pesticide residues on crops after spraying, samplers are often used to detect pesticide residues on the surface or inside the crops.

[0003] At present, when sampling pesticide residues in agricultural products, a common method is to place the agricultural products on a press to press and extract the liquid when preparing the sample liquid of the agricultural products. However, the liquid obtained by pressing the agricultural products is limited and the amount is very small, which is not convenient for extraction and sampling, and it is not easy to separate the solid and the liquid, thereby increasing the time for liquid sampling and reducing the efficiency of the detection. Therefore, a pesticide residue sampling device is needed to improve the above problems. Utility Model Content
