Single-point multi-depth sampling device for pesticide residue detection

Abstract

The invention discloses a single-point multi-depth sampling device for pesticide residue detection, belongs to the technical field of pesticide residue detection, and can conveniently tamp a samplingbarrel into soil, save time and labor, be convenient to operate and high in safety performance by arranging a specially-made lower tamping assembly. A worker can drive the soil sampling cutting ringsto break soil and rotate towards the corresponding sampling soil storage areas only through the simple operation of rotating the driving rotating shaft by holding the rotating handle rod by hand, andin the rotating process, the soil at the corresponding depth is collected. Finally, the soil with different depths is brought into a plurality of independently sealed sampling soil storage areas, so that the collection of the soil with different depths is synchronously completed at one time, the time and the labor are saved, the sampling efficiency and the pesticide residue detection efficiency are obviously improved, the mixing of the soil with other depths can be effectively prevented in the sampling process. And the sampling accuracy is effectively ensured.

Description

Technical field[0001]The invention relates to the technical field of pesticide residue detection, and more specifically to a single-point multi-depth sampling device for pesticide residue detection.Background technique[0002]Pesticides play an important role in agricultural production. In my country's agricultural production, there are many types of pesticides, including insecticides, herbicides, fungicides, rodenticides, and more than 600 types. The use of pesticides is a leap in agricultural production. In order to prevent the threat of pests and diseases and promote the growth of crops, the extensive use of pesticides in our country makes the soil pesticide residues high, which is likely to cause the accumulation of pesticide residues in animals or pesticide poisoning incidents, which will endanger public health. . Therefore, the detection of pesticide residues in the soil has become an important part of environmental testing.[0003]The detection and analysis of pesticide residues ...

AI Technical Summary

Problems solved by technology

[0004] Due to the penetration of pesticides in the soil, the content of pesticide residues in soil at different depths is not the same. Therefore, when sampling, it is necessary to sample soils at different depths. In the prior art, for different depths of soil Sampling often requires multiple sampling operations, which is not only time-consuming and laborious, but also seriously affects the efficiency of the entire detection, and is prone to inaccurate sampling
