Sleeve Sampler

technical field

The utility model relates to the technical field of auxiliary equipment for soil research, in particular to a sleeve type sampler.

Background technique

A soil sampler is a tool for collecting soil samples at different depths and soil textures. Existing soil samplers include small shovels, ring knives, earth drills, etc. The earth drills can be further divided into short-shank earth drills, screw-head earth drills, open earth drills, and sleeve earth drills. These soil samplers often have some problems: when collecting samples, certain soil samples will always stick to the wall of the sampler, which not only affects the soil samples this time, but also mixes with the samples collected next time, resulting in mixed pollution of multiple samples. Affect the test results; when the sample is transferred from the sampler, the original layer of the soil will be damaged to a certain extent, causing contamination of the sample in the vertical direction, thus affecting the test result; without setting the scale, it is difficult to accurately collect soil samples at a certain depth; After the sample, the remaining samples cannot be put back as they are, which may easily cause damage to the ecological environment. In order to solve the above problems and defects, it is imperative to improve the existing soil sampler.
