Description

Technical Field

[0001] The utility model relates to the technical field of soil detection, in particular to a surface soil stripping soil sampling and detection device. Background Art

[0002] With the development of society, the development of chemistry has been promoted. Land is often polluted by various sources, including chemical fertilizers or metal waste. The degree of pollution is so high that the soil itself is difficult to purify itself. Moreover, these polluted soils are washed into rivers by rainwater, which can easily cause eutrophication of river water. Therefore, soil testing is urgent. Technicians can develop different treatment plans to improve soil pollution based on the soil conditions after testing.

[0003] In the existing sampling process, most of the time only shallow soil sampling is carried out, and the samples obtained are relatively simple, which leads to a certain degree of randomness in the testing of the samples obtained. The method for testing the components in the soil is usually to collect soil samples and then bring the soil back to the laboratory for testing. However, in the process of bringing the soil samples back to the laboratory and testing, due to changes in the environment and time, the components of the soil samples will change, thereby affecting the accuracy of the test results.
