Description

Dust fall down-the-hole drill

Technical Field

The utility model relates to the technical field of down-the-hole drills, in particular to a dust-settling down-the-hole drill.

Background

The down-the-hole drill is an impact rotary drill, the internal structure of which is different from that of a common rock drill, and the gas distribution and piston reciprocating mechanisms of the down-the-hole drill are independent, namely an impactor. The front end of the drill is directly connected with a drill bit, and the rear end of the drill is connected with a drill rod. When drilling, the hammer is submerged into the hole, and the piston (hammer) in the hammer is reciprocated to strike the drill bit tail through the air distributing device (valve), so that the drill bit can impact the hole bottom rock. The high-speed rotation of the impactor in the hole is realized by a single rotating mechanism, namely an electric motor or a pneumatic rotating device outside the hole through a drill rod connected to the rear end of the impactor. Rock powder generated during rock drilling is flushed out of a discharge hole by air-water mixed gas, the mixed gas is injected into an impactor from a powder discharge mechanism through the center of a drill rod and then enters the bottom of the hole through an air groove in a cylinder body of the impactor, dust at a drill hole of a traditional down-the-hole drill in the using process can be lifted, a large amount of pollution can be caused, and related personnel need to correspondingly improve the structure of the drill in order to prevent the situation.
