Description

Technical Field

[0001] The utility model relates to the technical field of anchor drilling machines, in particular to an impact-proof pneumatic anchor drilling machine. Background Art

[0002] As we all know, pneumatic anchor drills are roadway anchor support equipment used in coal mines. They have outstanding advantages in improving support effects, reducing costs, speeding up roadway construction, reducing auxiliary transportation volume, alleviating labor intensity, and improving roadway section utilization. They are also widely used in the construction field. By adjusting the adjustment knob on the top of the anchor drill, the rotation parameters of the drill can be adjusted to prevent the rotation speed from being impacted in a hard position.

[0003] In daily work, it is found that when using pneumatic anchor drills to drill holes in the walls of mines, the pneumatic anchor drills have large body vibrations and cannot control the depth of the drill rod drilling well, resulting in reduced accuracy of the drilling depth.
