High Speed Rock Impact Alloy Steel HDD Pilot Hammer System
HDD Pilot Hammer System Has High-Speed Rock Impact
Introduction
Use HDD Pilot Hammer to cooperate with drilling rigs and corresponding drilling tools for impact rotary drilling. The HDD Pilot Hammer is connected to the bottom end of the drill rod. The drill rig drives the drill rod to rotate. Compressed air enters the HDD pilot hammer through the drill pipe to generate a certain frequency of impact force to break the rock. At the same time, the exhaust gas is used to cool the hammer head. Drain the debris from the hole. Because the outer diameter of the HDD pilot hammer is smaller than the drill diameter, it can be lowered into the hole as the drill depth increases. Compared with the pneumatic drill that impacts outside the hole, its impact power loss is small, and it can drill deeper holes.
