Description

Technical Field

[0001] The present invention belongs to the technical field of geological exploration, and particularly relates to a sampling device for geological exploration and a sampling method thereof. Background Art

[0002] Geological exploration can be generally understood as geological work. According to the needs of economic construction, national defense construction, and the development of science and technology, geological exploration methods such as surveying and mapping, geophysical exploration, geochemical prospecting, drilling, adit exploration, sampling and testing, and geological remote sensing are used to conduct investigative research on geological conditions such as rocks, stratigraphic structures, minerals, groundwater, and landforms in a certain area. During geological exploration, it is necessary to sample and test soil samples.

[0003] Most of the common sampling devices for geological exploration based on intelligent depth monitoring components on the market are used for sampling by manual excavation after finding a suitable position, which is time-consuming and laborious, and has low efficiency. At the same time, the device is prone to shaking during the sampling process, which is not conducive to the operation of the operator and has potential safety hazards.

[0004] The patent document with the publication number CN118757086A discloses a geological drilling physical detection device, which can be applicable to the drilling requirements of various environments and can sample at different drilling depths simultaneously.

[0005] The patent document with the publication number CN219810662U discloses a geological exploration sampling device. The lower surface of the movable collar of the device is fixedly connected with a blocking sleeve, the bottom end of the rotating shaft is fixedly connected with a drill bit, and an annular groove is formed on the outer surface of the rotating shaft. A storage groove is formed on the bottom wall of the annular groove, which can automatically move the drill bit downward while sampling. After the sampling is completed, since the spring is always in a compressed state, when the drill bit leaves the ground, the blocking sleeve completely covers the outside of the annular groove, which can protect the sampled soil.

[0006] The above two devices need to unload the material after one sampling before they can be used for the second sampling, which is not convenient for continuous multiple samplings. Among them, the patent document with the publication number CN118757086A can complete continuous collection without unloading by changing the drilling depth, but there are limitations when collecting soil at the same depth.
