Audited Supplier The down-the-hole drilling rig is an impact rotary drilling rig. Its internal structure is different from that of a general rock drill. Its gas distribution and piston reciprocating mechanisms are independent, that is, an impactor. The front end is directly connected with the drill bit, and the rear end is connected with the drill pipe. During rock drilling, the impactor dives into the hole, and through the gas distribution device (valve), the piston (hammer) in the impactor reciprocates to strike the shank, 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 rotating mechanism, that is, a motor or a pneumatic rotating device outside the hole, and a drill pipe connected to the rear end of the impactor. The rock powder generated during rock drilling is flushed out of the hole by the feng shui mixed gas. The mixed gas is injected into the impactor by the powder discharge mechanism through the center of the drill pipe, and then enters the bottom of the hole through the air groove on the impactor cylinder.
