Sampling device for geological mine exploration

Abstract

The invention relates to the technical field of underground mine exploration, and especially relates to a sampling device for underground mine exploration. The device comprises a seat body, telescopic pieces I are arranged at four corners of the outer wall of the seat body, a lifting plate is arranged at the telescopic ends of the telescopic pieces I, a driving piece is fixedly arranged on the lifting plate, a turntable is arranged at the driving end of the driving piece, a sampling barrel is connected to the outer wall of the rotating disc through a connecting rod, a cutting ring is arranged at the end of the sampling barrel, a round chamfer is arranged on the outer wall of the cutting ring, the inner diameter of the cutting ring is smaller than that of the sampling barrel, and the outer wall of the sampling barrel is sleeved with a dust cover. The dust cover on the outer side of the sampling barrel can always abut against ore through the limiting mechanism, dust overflowing during cutting is effectively prevented, meanwhile, as the inner diameter of the cutting ring is smaller than that of the sampling barrel, the situation that a sampled rock core is stuck in the sampling barrel and is difficult to take out can be avoided, and the sampled rock core can be easily pushed out of the sampling barrel.

Description

technical field [0001] The invention relates to the technical field of geological and mineral exploration, in particular to a sampling device for geological and mineral exploration. Background technique [0002] Geological prospecting is the investigation and research activities of conducting geological exploration and detection through various means and methods, determining the appropriate bearing layer, determining the foundation type and calculating the foundation parameters according to the foundation bearing capacity of the bearing layer. To discover mineral deposits with industrial significance, to ascertain the quality and quantity of minerals, as well as the technical conditions for mining and utilization, to provide mineral reserves and geological data required for mine construction design, to analyze rocks, strata, structures, minerals, hydrology in a certain area , geomorphology and other geological conditions to carry out investigation and research work.

AI Technical Summary

Problems solved by technology

[0003] In the process of geological and mineral exploration, sometimes the overall composition of the ore cannot be analyzed only by observing the surface of the ore. It is necessary to use a drilling device to drill the core of the ore in the middle of the ore, and observe the composition of the core. To analyze the ore as a whole, however, the existing sampling device still has some shortcomings. During the drilling process, the dust is easy to fly around, and the sample is easy to get stuck in the sampling device and it is difficult to take it out. Therefore, it is urgent to design a Sampling device for geological and mineral exploration to solve the above problems
