Description

Geological exploration sampling device Technical Field The utility model relates to the technical field of geological exploration, in particular to a geological exploration sampling device. Background Geological exploration is to survey and detect geology by various means and methods, determine a proper bearing layer, determine a foundation type according to the foundation bearing capacity of the bearing layer, calculate investigation and research activities of foundation parameters, and perform investigation and research work on geological conditions such as rock, stratum, structure, mineral, hydrology, landform and the like in a certain area, wherein the geological exploration often needs to be carried out by taking subsurface soil and analyzing. At present, in the geological exploration sampling process, a sampler is generally utilized for sampling, in the sampling process, as the inner side of the sampler is smooth, when the sampler is inserted into the ground for sampling and then is pulled out, a geological sample easily slides out of the sampler, so that the sample is scattered, and the sampling of the sample is influenced, so that improvement is needed. Disclosure of utility model The utility model aims to solve the technical problems of overcoming the defects of the prior art and providing a geological exploration sampling device which is used for solving the problems that in the prior art, during geological exploration sampling, a sampler is usually utilized for sampling, and during sampling, because the inner side of the sampler is smooth, a geological sample easily slides out of the sampler when the sampler is inserted into the ground for sampling and then is extracted, so that the sample is scattered and the sampling of the sample is influenced. In view of the above, the utility model provides a geological exploration sampling device, which comprises a sampling tube, wherein the top of the sampling tube is fixedly connected with a handle, one end of the sampling tube is provided with a drill bit assembly, and the middle of the sampling tube is provided with a material returning assembly; The drill bit assembly comprises a fixed head, a spiral drill bit, a fixed groove, a fixed bearing, a fixed ring and a plurality of elastic baffle strips, wherein the fixed head is in threaded connection with the bottom of a sampling tube, the spiral drill bit is arranged at one end of the fixed head, the fixed groove is formed in the inner side of one end of the spiral drill bit, the fixed bearing is fixedly arranged in the inner side of the fixed groove, the fixed ring is fixedly arranged in the inner side of the fixed bearing, and one end of each elastic baffle strip is fixedly connected with one end of the fixed ring.
