[0002] Soil testing refers to the process of collecting a certain quantity and quality of soil samples from the soil, testing and analyzing the soil through instruments to determine the various physical and chemical properties of the soil.

[0003] Soil testing has a wide range of application scenarios. Through soil testing, we can monitor the current status of soil quality, understand the physical and chemical properties of the soil, nutrient content, degree of pollution, etc., and promptly discover and evaluate the scope, extent and hazards of soil pollution accidents, providing scientific basis and data support for land use, agricultural production, environmental protection, pollution prevention and control, and ecological restoration.

[0004] Soil sampling is a particularly important step in the detection process, and the soil sampling device is an important basic tool in the soil detection process.

[0005] At present, soil sampling is commonly performed using a soil auger. Usually, an explorer holds the handle of the soil auger, aligns the drill bit of the soil auger vertically with the target soil position, presses the handle downward to allow the drill bit to penetrate the soil, and then pulls out the drill bit of the soil auger to obtain a soil sample. However, the force of pressing by hand is limited, and it is difficult for the drill bit to penetrate the soil, resulting in low efficiency of soil sampling. Therefore, it is necessary to propose a more efficient soil sampling device. Utility Model Content
