Description

Technical Field

[0001] The utility model relates to the field of soil detection equipment, in particular to a soil environment detection sampler. Background Art

[0002] Soil sampling and testing plays a very important role in modern agriculture, geology, water conservancy, environmental protection and other fields. Soil sampling and analysis of chemical substances and organic content in the soil in the laboratory can be used to determine the degree of environmental pollution and facilitate targeted protection of the environment.

[0003] There are various tools for soil sampling. The most common one is the soil sampler, which is also the easiest to carry and is very suitable for soil sampling in remote mountainous areas.

[0004] However, existing soil samplers all use direct downward pressure to collect soil. If the soil is relatively hard, it will be difficult to insert the soil sampler into the ground. If there are small roots of plants on the surface of the soil collection location, it is difficult to press the soil collection tube on the soil sampler under the soil by direct downward pressure alone. Moreover, the standard for collecting soil is generally 10-20 cm below the soil surface. Such operation seriously affects the progress of soil sampling, and it is not certain that the soil collection will be successful. Utility Model Content
