Description

Technical Field

[0001] The utility model belongs to the technical field of soil samplers, in particular to a soil sampler for land evaluation. Background Art

[0002] Soil sampling refers to the method of collecting soil samples, including the layout of the samples and the sampling technology. Sampling and spot checking the soil is a simple and intuitive means to understand geological information such as soil structure composition and pollution status. By observing and testing the collected soil core samples, the geological information that needs to be obtained can be quickly understood in order to conduct land assessment on the land in the target area. When taking soil samples, a soil sampler is usually used. After searching, the patent with application number 201922156245.4 discloses a soil sampler for land assessment, including a sampling base, a support rod, a fixing plate, a drive structure, a rotating shaft, a pressure plate, a limit hole, a slide rod, a pressure bump, a pressure plate, a torsion spring, a collection structure and a sampling tube.

[0003] However, in actual use, the applicant found that when using a sampling tube to sample the soil, a person needs to manually drive the pressure plate back and forth to drive the sampling tube to rotate and screw the sampling tube into the ground for sampling. This operation is not labor-saving enough. In view of this, we propose a soil sampler for land assessment. Utility Model Content
