The
pneumatic rock drill is an impact drilling machine which is driven by compressed air. According to the propulsive way and divided into hand-held drill, pneumatic leg drill, telescopic upward drill and guide type drill.
Pneumatic rock drill working principle
When the pneumatic rock drill is working, the air pressure enters the back chamber and the front chamber of the cylinder alternately, pushing the piston back and forth. Similarly, the compressed air also ACTS on the back cover or front cover of the cylinder, making the drill go backward or forward, so that the drill produces vibration, resulting in gouging force.
Pneumatic rock drill machine composition
Pneumatic rock drill mainly consists of cylinder - piston components, gas distribution device, steel slewing mechanism, control valve and flushing - blowing mechanism. Pneumatic rock drill in the operation of the useful hand support, known as the hand-held drill; Have the use of pneumatic leg, known as the air leg drill; There is the use of pneumatic column rail, known as the column rail drill; There are also in a car frame equipped with one to several drill, known as the drill.
