[0002] Environmental protection projects refer to projects specifically designed for environmental protection. Due to industrial development leading to environmental pollution, environmental pollution is dealt with and resolved through the organized activities of a group of people based on a set of envisioned goals and the application of relevant scientific knowledge and technical means.

[0003] In the prior art, in environmental protection projects, it is necessary to sample the soil to detect whether the soil is contaminated, and in many cases it is necessary to sample the soil at different depths to detect the degree of soil contamination. In the existing soil sampling device, when sampling deeper soil, since the sampling equipment goes directly from the surface to the deep, the surface soil is easily mixed with the deep soil sample, which affects the accuracy of the test results. Therefore, we propose a soil sampling device for environmental protection projects. Utility Model Content
