Soil sampling device

Abstract

The invention discloses a soil sampling device in the technical field of soil sampling. The soil sampling device comprises a supporting base; a cylinder is integrally welded in the top center of the supporting base; an outer sampling column is sleeved in the cylinder; an inner sampling column is inserted into the outer sampling column; a sampling port is disposed in the bottom of an outer wall ofthe outer sampling column; a cross section of the sampling port is a long-striped rectangle; the bottom of the outer wall of the inner sampling column is provided with a collection port the same as the sampling port; a screw drill bit is mounted at the bottom of the sampling column. The soil sampling device is convenient to assemble and carry; by disposing a bearing plate, the pressure of the supporting base is increased conveniently and the sampling is more stable; the downward force is applied through the outer sampling column, and the screw drill bit is matched for drilling, thus the sampling is labor-saving according to the drilling depth; after the sampling depth is reached, the inner sampling column can be rotated, the sampled soil block is collected, a fixed sleeve is conveniently opened and the sampled soil block is taken out.

Description

technical field [0001] The invention relates to the technical field of soil sampling, in particular to a soil sampling device. Background technique [0002] Soil is the foundation of human existence and the most important resource for the development of economy and agriculture. However, with the continuous emergence of environmental problems, soil environmental problems have become the focus of people's attention. In order to solve the problem of soil environmental quality, people have carried out many related researches. The analysis and determination of collected soil samples can provide a data basis for soil pollution investigation and research. Therefore, the scientificity, representativeness and normativeness of sample collection are very important. Soil samplers have been widely used in the fields of soil, geology, water conservancy, and environmental protection. Using a reasonably designed soil sampler can not only greatly reduce the workload of soil surveys, shorten...
