Soil sample collection tool

Abstract

The invention discloses a soil sample collection tool. The soil sample collection tool comprises a sampling tube, a soil boring assembly, a first cylinder, and a soil cutting assembly, wherein the sampling tube is formed by coaxially splicing an upper portion and a lower portion, the outer circumferential surface of the lower portion of the sampling tube is uniformly provided with six ribbed blocks at interval along the circumferential direction, six first through holes are arranged in the wall of the sampling tube from top to bottom along the straight line, an upper opening of the first through hole is positioned on the upper end surface of the upper portion of the sampling tube, a lower opening of the first through hole is positioned on the lower end surface of the ribbed block, and thelower openings of the six first through holes are respectively correspondingly arranged in the six ribbed blocks; the soil boring assembly comprises six spines and an annular end plate connecting thesix spines; the first cylinder is detachably connected to the upper end of the sampling tube by virtue of threads so as to abut against the annular end plate; and the soil cutting assembly comprises asecond regular quadrangular column and a second regular quadrangular cone. By adopting the soil sample collection tool, the accuracy for sampling the soil at a predetermined depth can be ensured, andthe completeness and effectiveness of an obtained soil sample can be kept.

Description

technical field [0001] The present invention relates to the field of soil sampling. More specifically, the present invention relates to a soil sample collection tool. Background technique [0002] At present, when analyzing and studying the soil environment in a certain area, the soil must be sampled first. The soil to be sampled is preferably soil with a certain depth, so that a more comprehensive and accurate analysis of the soil condition can be made. The samplers in the prior art usually insert the pipe body parts into the soil, then pull them out, and then take out the soil in the pipe body by other methods, but generally the soil has a certain viscosity. After the pipe body parts are inserted into the soil, It can only separate the soil on the inner and outer sides of the pipe wall, and cannot effectively separate the soil at the lower port of the pipe body. Therefore, when the pipe body is pulled out, the sampler may not be able to take out the soil due to the visco...

The samplers in the prior art usually insert the pipe body parts into the soil, then pull them out, and then take out the soil in the pipe body by other methods, but generally the soil has a certain viscosity. After the pipe body parts are inserted into the soil, It can only separate the soil on the inner and outer sides of the pipe wall, but it cannot effectively separate the soil at the lower port of the pipe body. Therefore, when the pipe body is pulled out, the sampler may not be able to take out the soil due to the viscosity of the soil. Partial soil, nor a soil sample of the depth desired to be tested
