[0002] Soil testing is a series of physical, chemical and biological analysis processes conducted on soil samples to evaluate the quality, health of the soil and its suitability for specific purposes (such as agricultural planting, environmental protection, land development, pollution investigation and control, etc.). Soil testing requires sampling of soil at different depths.

[0003] Based on the above, the inventors have found that the following problems exist: current soil sampling usually uses a manual soil drill, which is relatively portable, but the soil drill needs to drill the soil in layers. After each layer of soil drilling is completed, the soil drill needs to be removed from the borehole, and the soil needs to be taken out of the drill barrel through the soil extraction groove, and then drilling is carried out. This method is more cumbersome to operate, and the soil inside each drill barrel will be mixed together when it is taken out, which cannot well reflect the state of the soil at different depths and is inconvenient to use.

[0004] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a sampling device with different depths for soil testing is provided, in order to achieve a more practical purpose. Utility Model Content
