Rapid sampler for shallow soil sample

Abstract

The invention relates to a rapid sampler for a shallow soil sample. The rapid sampler comprises a soil sampling sleeve and a soil sampling pipe installed in the soil sampling sleeve. The soil sampling pipe can be taken out from the soil sampling sleeve. A soil sampling annular clearance is formed between the soil sampling pipe and the soil sampling sleeve. After the upper end of the soil sampling sleeve is flush with the upper end of the soil sampling pipe, the soil sampling sleeve and the soil sampling pipe are internally and externally fixed through a chuck, the outer wall of the lower end of the soil sampling pipe is evenly provided with a plurality of bent teeth bent in the same circumferential direction, a driving shaft is installed in the center of the upper end of the soil sampling pipe through a connecting rod, and a manual rotating rod is installed at the upper end of the driving shaft in the radial direction; a reinforcing ring is arranged on the outer wall of the soil sampling sleeve, the two opposite sides of the reinforcing ring are symmetrically provided with steel pull belts, and the ends of the steel pull belts are provided with pull rings. According to the sampler, the internal and external soil sampling sleeve and soil sampling pipe structure is adopted, soil sampling is performed through the soil sampling annular clearance between the soil sampling pipe and the soil sampling sleeve, the soil sample is packaged after the bent teeth at the lower end are rotated, the soil sample is effectively prevented from being disengaged, one-time soil sampling can be achieved, time and labor consumed by repeated soil sampling are avoided, and the soil sampling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of geological exploration, in particular to a hand-held soil fetcher. Background technique [0002] In the field of geological exploration, soil fetches are often used when collecting soil samples. At present, the soil fetches mainly used are hand-held soil fetches, which are specially used for shallow soil fetching, and preliminary detection of the geological surface to determine whether deep soil is needed. sampling. Existing hand-held soil fetchers, especially for loose soil sampling, generally adopt a soil-taking sleeve, and utilize the sleeve pipe at the end to insert into the soil, and retain soil in the sleeve pipe when pulled out. Although the soil extractor of this structure is simple in structure, the soil sample in the sleeve pipe is easy to come off, therefore needs to fetch soil repeatedly, and efficiency is not high. [0003] On the same day, the applicant applied for a patent titled "Handhel...
