Introduction of rock drill:The air-leg rock drill is a high-efficiency rock drilling machine. It is widely used in rock tunnel excavation and drilling blasting holes in various rock drilling operations.
The air-leg rock drill relies on compressed air to push the piston to reciprocate. During the stroke, the piston hits the shank, and during the return, the piston drives the drill to rotate to achieve rock crushing and drilling.
The use of full hydraulic drilling rigs to replace air-leg rock drills is an inevitable trend in the development of coal mine rock roadway excavation, but at present, more than 90% of the rock roadway excavation construction is dominated by air-leg rock drilling.
Features of rock drill:Air-leg rock drills are hand-held, semi-mechanized (manually operated, manual moving equipment) products with a wide range of products. It is easy to operate and maintain, cheap, but has low drilling speed, large operating noise, many occupants, low efficiency, high labor intensity, and prone to accidents such as mechanical accidents and roof safety.
