High-quality KQD100 underground drilling rig

The down-the-hole drill is a core mechanical device that is highly efficient and suitable for rock drilling scenarios. Its core advantages lie in "coordinated transmission structure + multi-scenario adaptability + strong durability", which can precisely meet the high-intensity operation requirements of the mining and excavation industries. It adopts the collaborative working principle of "motor rotation + impactor reciprocation" : the motor provides stable rotational power, driving the overall positioning and adjustment of the equipment; The impactor drives the drill bit to act on the rock through high-frequency reciprocating motion, which can not only achieve efficient stone extraction (stone quarrying), but also precisely complete grouting (grouting) drilling, avoiding the problems of low drilling efficiency or rapid drill bit wear caused by a single transmission method. Its application scenarios cover an extremely wide range. It can not only efficiently drill rock blasting holes in…
