Coal sampling machine convenient to clean and used for gas extraction

Abstract

The invention discloses a coal sampling machine convenient to clean and used for gas extraction. The coal sampling machine is placed at a corresponding position through a fixing frame, two supporting columns are arranged at the bottom of the fixing frame, a mounting plate is arranged between the two supporting columns, the top of the mounting plate is connected with the output end of a hydraulic cylinder. The coal sampling machine comprises a drill rod arranged under the mounting plate, a limiting block arranged at the top of a rotating rod, and a fixing plate is mounted on the inner walls of the supporting columns. According to the coal sampling machine convenient to clean and used for gas extraction, the fixing plate is arranged between the supporting columns, brushes are installed at the end, away from the supporting columns, of the fixing plate, the brushes are attached to the outer wall of the drill rod, and after the drill rod is used, a worker can start a hydraulic cylinder to enable the hydraulic cylinder to push the mounting plate to drive the drill rod to move up and down, and further the drill rod moves vertically in the brushes. The surface of the drill rod is cleaned through the brushes, and normal use in the later period is guaranteed.

Description

technical field [0001] The invention relates to the technical field of gas drainage, in particular to a coal sampling machine for convenient cleaning of gas drainage. Background technique [0002] Gas extraction can refer to the sampling of coal samples. By testing the samples taken, the coal can be better mined and utilized. [0003] However, existing coal sample sampling machines still have some deficiencies during use, for example, it is not convenient to sample coal samples when drilling. Existing all are to use sampling equipment after drilling to a certain position. Sampling is cumbersome and reduces sampling efficiency, and it is not convenient to clean up the equipment after sampling, which affects the subsequent use and thus reduces the efficiency of the sampling machine. Therefore, we propose a gas pump that is easy to clean. Coal sample sampling machine, in order to solve the problems raised in the above. Contents of the invention [0004] The purpose of the p...
