The down-the-hole drill rig is indeed an impact rotary drill rig that operates differently from a conventional rock drill. Its internal structure features an independent gas distribution and piston reciprocating mechanism, known as the impactor. The impactor is directly connected to the drill bit at the front end and connected to the drill rod at the rear end.

During the rock drilling process, the impactor moves into the hole. Through the gas distribution device (valve), the piston (hammer body) inside the impactor reciprocates, delivering impacts to the bit shank. This action generates a rotational force on the drill bit, enabling it to effectively penetrate and impact the rock at the bottom of the hole. This impact rotary mechanism helps to enhance the drilling efficiency and overall performance of the down-the-hole drill rig.
