The
pneumatic rock drill is to continuously impact the drill tail by the piston, and continuously input compressed air or pressure water from the central hole of the drill, the slag out of the hole, that is to form a certain depth of the circular drill.
Pneumatic rock drill with compressed air to drive the piston in the cylinder forward impact, so that the chisel rock, the most widely used. The motor drives the hammer head through the crank link mechanism to strike the steel bit and chisel the rock. And the use of powder discharge mechanism to discharge stone debris, internal combustion engine using the principle, through the combustion and explosive force of gasoline piston impact steel, chisel rock.
Pneumatic rock drill is suitable for construction site without power supply and air source. The hydraulic type relies on the hydraulic pressure through the inert gas and the impact body to strike the steel, chiseling the rock. The impact mechanism of these rock drills in the return trip, by the rotating mechanism to force the steel rotation Angle, so that the drill head change position to continue to chisel the rock. Through the diesel combustion force to drive piston impact steel, so constantly impact and rotation, and the use of powder discharge mechanism to discharge stone, can be drilled into the hole.
