Description

Technical Field

[0001] The present invention relates to the technical field of soil monitoring, and in particular to a sample collection device for soil survey. Background Art

[0002] Soil environmental monitoring refers to determining the environmental quality (or pollution level) and its changing trends by measuring the representative values of factors affecting soil environmental quality.

[0003] At present, most soil surveys and monitoring processes are carried out manually with shovels, or with more expensive electric drilling tools. The former method is time-consuming and labor-intensive, while the latter method is expensive and the electric device is heavy and inconvenient to carry. At the same time, after the sampling device is used, the outer wall is prone to adhesion of soil and other materials, which will affect the mining effect and quality in subsequent long-term use, and it is easy for new soil and old soil to mix and affect the test results.

[0004] Therefore, we propose a sample collection device for soil survey in order to solve the above problems. Summary of the Invention
