Spiral collector for paddy deep soil and using method thereof

Abstract

The invention discloses a spiral collector for paddy deep soil and an operation method thereof. The soil collector comprises a sampling tube, a bracket for fixing the sampling tube, and a support basefixed to the bottom of the bracket. The support base comprises a support table, a circular block, a T-shaped fixing bolt, a strut fixing seat, and a water blocking cylinder. The bracket comprises a strut disc, a common strut, a grooved strut, a strut disc groove, a strut disc hole, and a strut insertion hole. The sampling tube comprises a sampling tube body, a T-shaped screw, a sampling tube tophole, a bearing, a bearing fixing plate, a bearing connecting ring, a vent pipe, a vent pipe sealing cap, a piston, a sliding bar, a gas path, a gas pressure balance port, and a gas stop valve. The paddy deep soil sample collected by the soil collector can retain the structural characteristics of the in situ soil, and has the advantages of simple structure, convenient operation, and less sample contamination.

Description

technical field [0001] The invention relates to a spiral paddy field deep soil collector and a using method thereof. Background technique [0002] At present, in the fields of geochemistry, microbial ecology, and environmental science, there are more and more studies on the anaerobic process of microorganisms in deep soil. Paddy fields are an important habitat for anaerobic microorganisms, especially active anaerobic microbial activities occur in the deep soil of paddy fields, such as anaerobic oxidation of methane catalyzed by microorganisms, microbial reduction of metal elements such as iron and manganese, and anaerobic degradation of organic pollutants . However, it is difficult to collect deep soil samples in paddy fields, and there is no simple and efficient sampler so far, which greatly restricts the further development of related research. Existing soil sample collectors include small shovels, ring cutters, soil drills (the most commonly used), etc., and soil drills...

AI Technical Summary

Problems solved by technology

On the one hand, when these soil sample collectors collect paddy field soil samples, the overlying water and surface mud in the paddy field will inevitably flow into the sampling hole, polluting the deep soil samples, and it is difficult to collect unpolluted deep soil samples of paddy fields; On the one hand, traditional sampling devices require multiple operations to collect deep soil samples, which is time-consuming and laborious
