Geological exploration sampler

Abstract

The invention discloses a geological exploration sampler, and belongs to the technical field of geological exploration, the geological exploration sampler comprises a sampling cylinder, the top end of the sampling cylinder is provided with an opening and closing adjusting cylinder matched with the sampling cylinder, and the inside of the opening and closing adjusting cylinder is movably provided with a piston plate matched with the opening and closing adjusting cylinder. When the sampler is specially used for manufacturing, designing and sampling wetland soil with high flowability, after the sampling barrel is inserted into the wetland soil, the adjusting rod is pressed to enable the heating ball to fall into clear water, so that the sampling barrel and the opening and closing adjusting barrel can be automatically separated, and sampling is carried out; when the sampling barrel is pulled out, the pressure relief function of the self-air-leakage driving closing part can be automatically triggered, then the sampling barrel and the opening and closing adjusting barrel are automatically closed, then sampling can be completed by pulling out the sampling barrel, soil can be effectively brought out, the sampling efficiency is improved, when the sampling barrel is pulled out, soil above cannot flow into the sampling barrel, and then the sampling accuracy can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of geological exploration, and more specifically relates to a sampler for geological exploration. Background technique [0002] Geological exploration can be understood as geological work in a broad sense. It is based on the needs of economic construction, national defense construction, and scientific and technological development, using geological exploration methods such as surveying and mapping, geophysical prospecting, geochemical prospecting, drilling, pit exploration, sampling testing, and geological remote sensing. , Investigation and research work on geological conditions such as rocks, stratum structures, minerals, groundwater, and landforms in a certain area. [0003] When carrying out geological exploration, it is often necessary to use a soil sampler to sample the soil. In the prior art soil sampler, the bottom of the sampling cylinder is usually set in an open shape. The sampler is inserted into...

Problems solved by technology

[0003] When carrying out geological exploration, it is often necessary to use a soil sampler to sample the soil. In the prior art soil sampler, the bottom of the sampling cylinder is usually set in an open shape. The sampler is inserted into the soil, and then the sampler is pulled out. A certain amount of soil samples can be brought out, but when sampling the soil in the wetland area, especially when sampling the wetland soil with high fluidity, the soil samples will continue to flow out during the process of pulling out the sampler The sampling cylinder cannot effectively take out soil samples. Even if it can take out soil samples, the amount of soil samples taken out each time is very small, and the sampling efficiency is low, which is not conducive to geological exploration.
