What is the working principle of air leg rock drill?

Working principle of air leg rock drill:

The rock drill uses compressed air to push the piston back and forth. during stroke. Piston impact drill to chisel rock: when returning, the piston drives the drill to rotate by a certain angle. continuous impact. Rotation causes the drill to chisel round holes in the rock.

Air leg rock drill is a modern rock drill product. It adopts the design technology of modern rock drill. Compared with the same type of products, it has the advantages of low noise, light weight, good economic effect and fast footage. YT28 pneumatic drill, using reliable rock drill. It is suitable for large-scale mines, medium-sized mines and rock drilling operations in tunnels. It is well received by domestic users and has a market share of more than 70%. It adopts mechanisms such as air-water linkage, rapid return of air legs, and air pressure adjustment. The control handle is centralized with the handle body, the mechanism is novel and the operation is convenient. The equipped muffler cover can effectively reduce the noise and change the exhaust direction at will, and improve the working conditions on site.

Application of air-leg rock drills and mining, roadway excavation and various rock drilling operations. It is an important tool in metallurgy, coal, railway, transportation, water conservancy, infrastructure and stonework engineering. This machine is suitable for wet drilling of medium-hard or hard rock, with a muzzle diameter of 34-42mm and a drilling depth of 5m.
