[0002] With the continuous advancement of industrialization, the problem of soil pollution has become increasingly prominent. Land is often polluted from different fields, such as chemical fertilizers, metal waste, etc. It is difficult for the soil itself to purify itself in a short period of time, and these polluted soils are easily washed into rivers by rainwater, which can easily cause eutrophication of river water. Through soil testing, the pollution status of soil in a specific area can be obtained in time, and different governance plans can be formulated to improve soil pollution.

[0003] The soil detection device in the prior art uses a simple sampling tool to collect samples and then uses an analytical instrument to detect the samples. When performing the detection, the soil needs to be sampled before the detection. The position of the sampling mechanism is fixed when the sampling tool is sampling and it is inconvenient to adjust. After the sampling and detection, the soil is sticky and will adhere to the detection device and the sampling device, which is inconvenient to clean. In addition, the contaminated soil is usually corrosive.
