A fast wetland soil collector

Abstract

The invention discloses a tight wetland soil collector. The tight wetland soil collector comprises a hollow casing pipe and an inner pipe, wherein the inner pipe is arranged in the casing pipe and is used for collecting soil, a bearing disc arranged at the bottom of the casing pipe is used for bearing the inner pipe, and the upper parts of elastic metal sheets arranged on two sides of the bearing disc can swing freely. In the course of collecting soil, the elastic metal sheets are pressed against the inner wall of the casing pipe, then the upper parts of the elastic metal sheets are fixed on the inner wall of the casing pipe by clamping fasteners so that high-pressure springs are contracted, and the inner pipe filled with collected soil is put in the casing pipe. Because the soil is wet and loose, the elastic metal sheets need to be released from the clamping fasteners to press the inner pipe tightly under the action of the high-pressure springs and apply pressure to the inner pipe so that the flow of soil can be reduced and the soil can be hold still relatively and kept unchanged.

Description

technical field [0001] The invention relates to a collector, in particular to a fast wetland soil collector. Background technique [0002] As we all know, the environment of each place is different, and the soil environment brought by it will also be different, and the composition, structure, and water content of the soil will also be different, and the wetland soil is saturated with water content. The fluidity is stronger. In the process of sampling and sampling separation of ordinary cylindrical samplers, the extrusion friction between the sampler and the soil is easy to make the soil flow mixed. After the sampling is completed, it is difficult to maintain the original nature of the material distribution in the soil layer. . Contents of the invention [0003] In order to overcome the above problems, the present invention provides a fastened wetland soil collector with simple structure and good effect of maintaining the original property of the soil layer. [0004] The ...
