Technical field

The utility model relates to the technical field of soil sampling, and in particular to a soil layered sampling structure.

Background technique

Soil sampling and testing is an important part of environmental testing. In the field of environmental testing, soil is a key medium that can carry and store many important substances, including organic compounds, inorganic substances, heavy metals and other pollutants. By sampling and testing soil, the quality and contamination status of the soil can be assessed and important environmental information provided. When collecting samples, use special tools (such as soil drills, soil hoes or soil columns) to divide the soil profile into different layers according to the set depth, and collect samples at each layer. These samples can be used for research and evaluation in fields such as soil physical and chemical property analysis, nutrient content detection, and environmental monitoring.

The support mechanism is located below the device body. The driving mechanism is located at the upper end of the support mechanism, and the collection mechanism is located in the middle of the lower end of the driving mechanism. The collection mechanism includes a collection rod, a core rod, a storage slot, an electric push rod and a collection box. The soil layered sampling structure of this environmental testing is used. When used, the collection rod is penetrated deep into the required soil layer, and then the electric push rod is driven to make the collection box penetrate deep into the soil. At this time, the collection rod is rotated to move the collection box to its location. After the soil is collected, the electric push rod will retract the collection box to the inside of the storage tank. The outer end of the collection box fits the outer end of the collection rod, so that the outer end of the collection rod remains smooth, increasing the Mobility in the soil. The above-mentioned patent has the following shortcomings in actual use: during use, the downward pressure rod pushes the collection rod deep into the soil. During this process, the collection rod squeezes the soil, making it difficult for the collection rod to descend, or the descending depth is shallow. It affects the collection effect, and the electric push rod is installed in the rotating collection rod. Its structure is relatively complex, the use cost is high, and it is difficult to popularize and use it.
