Product details

The DTH drilling rig is a rock drilling equipment for downhole drilling. The essence of the downhole rock drilling is to infiltrate the impactor into the hole during the rock drilling process to reduce the energy loss caused by the impact energy transmitted by the drill rod, thereby reducing the influence of the hole depth on the rock drilling efficiency.

Product features:

The DTH Drilling rig is a percussion rotary drilling rig,The DTH Drilling rig internal structure and the general drill is different, its valve and piston reciprocating mechanism is independent, that is, the impactor. The front end is directly connected to the drill bit and the rear end is connected to the drill pipe. When drilling, the impactor penetrates into the hole and makes the piston (hammer) reciprocate in the impactor to hit the bit tail through the air distribution device (valve), so that the drill bit impacts the rock at the bottom of the hole. The high-speed rotation of the impactor in the hole is realized by a separate rotary mechanism, that is, the motor outside the hole or the wind-driven rotating device, through the drill pipe connected to the rear end of the impactor. The rock powder produced during drilling is flushed out of the hole by the fengshui mixed gas. The mixed gas is injected into the impactor by the discharge mechanism through the center of the drill pipe and then into the bottom of the hole through the air groove on the cylinder block of the impactor.
