Rock-soil sampling device with gravel removal function and for geological survey

Abstract

The invention discloses a rock-soil sampling device with a gravel removal function and for geological survey in the technical field of rock-soil sampling. The rock-soil sampling device comprises a rack, an insertion hole is formed in the top of the rack, a cylinder is inserted in the insertion hole, rock-soil collecting assemblies are arranged on the left side and the right side of the top of the rack, and a rotating rod is mounted at the center of the top of a top cover through the rear side. Mounting holes are formed in the left side and the right side of the top of the top cover, movable cylinders are mounted in the mounting holes through bearings, large-particle rock soil and hard soil blocks hit a buffer layer and then are blocked by a filter screen, the largest-particle rock soil and hard soil blocks are discharged through a discharging pipeline, and if the part does not meet the standard of collecting rock soil samples, the part can be directly discharged. Rock soil and hard soil blocks filtered by the filter screen fall into a collection box and are collected and detected together with fine rock soil samples, the rock soil samples can be collected in a classified mode, and after two kinds of rock soil particle samples with different diameter specifications are collected, detection data are more comprehensive and more accurate.

Description

technical field [0001] The invention relates to the technical field of geotechnical sampling, in particular to a geotechnical sampling device for geological surveys with a crushed stone removal function. Background technique [0002] In the process of geological survey, soil sampling devices are usually used for excavation and sampling. However, when surveying rock and soil areas with complex soil environment, since the rock and soil will be mixed with a large amount of debris such as gravel, during soil testing, it is necessary to Manual sieving is used to screen out the gravel and large particles of rock and soil in the sample. Although this operation can screen out the finely divided soil, a large number of soil samples will be discarded, which may reduce the accuracy of soil sample detection data. To this end, we propose a geotechnical sampling device with the function of removing gravel. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to pro...

[0002] In the process of geological survey, soil sampling devices are usually used for excavation and sampling. However, when surveying rock and soil areas with complex soil environments, because the rock and soil will be mixed with a large amount of debris such as gravel, it is necessary to perform soil testing. Manual sieving to sieve out gravel and large-grained rock and soil in the sample. Although this operation can sieve out finely divided soil, it will discard a large number of soil samples, which may reduce the accuracy of soil sample detection data. To this end, we propose a geotechnical sampling device for geological survey with the function of removing gravel
