Problems solved by technology

[0002] Before the construction of the project, it is necessary to carry out geological survey, analyze the existing geological problems, and formulate the construction plan. Among them, the sampling of rock and sand is very important. The rock and soil fell during the process, and the sampling results were not accurate enough
[0003] Before sampling with the existing sampling equipment, it is necessary to use a punching device to carry out a hand-held punching, and then use the sampling device to take a sample, which affects the work efficiency, and when punching, it will generate a large vibration, and it is easy to pop out stones and sand, which affects the observation work status , and there are security risks

Abstract

The invention relates to a rock exploration sampling device which comprises a fixed table, a driving device is mounted on the fixed table, a hydraulic cylinder is mounted below the fixed table, and a sampler is connected to the bottom of the hydraulic cylinder; the sampler comprises a driving rod, a sampling pipe and a drill rod which are sequentially connected into a whole, a drill bit is arranged at the tail end of the drill rod, and the driving rod is connected to the output end of a hydraulic cylinder; and the sampling tube comprises a sampling inner tube and a sampling sleeve sleeved outside the sampling inner tube. The device integrates drilling and sampling functions, can prevent gravel from splashing during drilling, and is convenient for observing the state. The detachable reinforcing supporting frame is not prone to deviation, the sampling process is stable and efficient, the sampling position is monitored and determined, the sampling accuracy is improved, the sampling pipe is closed, sampling can be more accurately completed, time and labor are saved, energy is saved, environment friendliness is achieved, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of rock and soil surveying equipment, in particular to the technical field of rock surveying and sampling devices. Background technique [0002] Before the construction of the project, it is necessary to carry out geological survey, analyze the existing geological problems, and formulate the construction plan. Among them, the sampling of rock and sand is very important. The rock and soil fell during the process, and the sampling results were not accurate enough. [0003] Before sampling with the existing sampling equipment, it is necessary to use a punching device to carry out a hand-held punching, and then use the sampling device to take a sample, which affects the work efficiency, and when punching, it will generate a large vibration, and it is easy to pop out stones and sand, which affects the observation work status , and there are security risks. Contents of the invention [0004] The purpose of the...
