Description

Technical Field

[0001] The utility model belongs to the technical field of geochemical sampling, in particular to a sampling device for geochemical prospecting. Background Art

[0002] Sampling device for geochemical prospecting: a tool used to obtain geological samples for geochemical analysis. These devices are usually designed to take samples from the surface or underground to collect samples including rocks, soil, sediments and water. The design of the sampling device depends on the type of target sample, the sampling location, and the required accuracy and representativeness. By performing geochemical analysis on the collected samples, geologists can evaluate information on geological structure, ore deposit type and resource potential, thereby guiding mineral exploration and development activities.

[0003] The existing sampling device for geochemical prospecting needs to take samples of soil layers at different depths when sampling different underground areas. The height that the existing sampling device can adjust is limited, and when the height of the sampling device is high, the stability is poor, and it is easy to produce angle deviation, which affects the validity of the sample data. At the same time, when the existing sampling device drills holes in the soil layer, some soil samples at other depths are easy to mix with the soil samples that need to be taken, reducing the sampling quality. To this end, we provide a sampling device for geochemical prospecting to solve the above problems. Utility Model Content
