Problems solved by technology

The bolter uses cemented carbide drill bits in the construction of soft rock formations and coal seams. When encountering gangue, workers have only two options: one is to continue grinding hard rock with cemented carbide drill bits. The drilling rig can only carry out rotary drilling movement, so the construction efficiency is extremely low, and a large number of drill bits will be damaged; the other is to withdraw the drilling rig and drill pipe and replace it with a very expensive PDC composite drill bit for grinding and drilling. This construction method improves Reduce the construction cost and reduce the efficiency of drilling construction

Abstract

The invention provides a pneumatic anchor rod drilling machine, which comprises a main shaft component, a pneumatic motor and a vibratory percussion component, wherein a main shaft is arranged in the main shaft component; the pneumatic motor is linked with the main shaft component through a gear train; the vibratory percussion component is connected with the main shaft component, and is used for transmitting vibration for the main shaft. According to the pneumatic anchor rod drilling machine, rotating movement, percussion movement and vibratory rotating movement can be realized, so that the pneumatic anchor rod drilling machine is endowed with a rotating drilling function, a percussive rock drilling function and a vibratory cutting function, different functions can be selected for construction during coal mine production according to different geological conditions, the drilling speed of a coal mine can be effectively increased, and the productivity of the coal mine can further be improved.

Description

technical field [0001] The invention relates to the field of mining machinery, more specifically, to a pneumatic rock bolt drill. Background technique [0002] At present, when drilling into gangue and hard rock that are often encountered in coal mines, drilling is mainly carried out by pneumatic bolters, and there is no efficient and reasonable solution. The bolter uses cemented carbide drill bits in the construction of soft rock formations and coal seams. When encountering gangue, workers have only two options: one is to continue grinding hard rock with cemented carbide drill bits. The drilling rig can only carry out rotary drilling movement, so the construction efficiency is extremely low, and a large number of drill bits will be damaged; the other is to withdraw the drilling rig and drill pipe and replace it with a very expensive PDC composite drill bit for grinding and drilling. This construction method improves The construction cost is reduced, and the efficiency of d...
