AI Technical Summary

Technical Problem

In the prior art, it is difficult to form close contact with the inner tube, resulting in the middle of the sample break or overall fall off, affecting the integrity and accuracy of sampling, and the residual sample hinders subsequent sampling and reduces efficiency.

Method used

An anti-dust sampling device is adopted, including a drilling assembly, a drilling tube assembly, a sampling inner tube and an extraction rod. The elastic strip is squeezed through the tightening controller to make it bend and deform inward, ensuring that the soil sample is tight in the sampling inner tube, and a locking sleeve and unlocking structure are used to achieve stable extraction of the sampling inner tube, and dustproof components are equipped to reduce dust flying.

Benefits of technology

It improves the integrity and accuracy of sampling, reduces sample shedding, improves sampling efficiency, and reduces the impact of dust on the environment.

Abstract

The invention discloses a dust raising prevention sampling device and method for geological mineral exploration, and particularly relates to the technical field of geological exploration, the device comprises a drilling assembly, a drilling pipe assembly, a sampling inner pipe and an extraction rod, the drilling assembly comprises a drilling machine and a feeding driving frame, the drilling pipe assembly comprises a section of primary drilling pipe and a plurality of sections of secondary drilling pipes, the sampling inner pipe is arranged in the primary drill pipe, a plurality of groups of elastic pressing strips are arranged at the bottom end of the sampling inner pipe, and a tightening controller is further arranged on the outer side of the bottom of the sampling inner pipe. When the sampling inner pipe is lifted, the tightening controller extrudes the bottom end areas of the elastic pressing strips, so that all the elastic pressing strips are bent and deformed inwards, a soil sample entering the sampling inner pipe is extruded to a certain extent, and the carrying capacity of the soil sample is improved; furthermore, the soil sample in the sampling inner pipe can be effectively taken out when the sampling inner pipe ascends, and the sampling integrity and accuracy are greatly improved.
