Down-the-hole drill with dustproof function and use method thereof

Abstract

The invention belongs to the technical field of rock drilling, and particularly relates to a down-the-hole drill with a dustproof function and a use method thereof. The down-the-hole drill comprises adust removal mechanism, the dust removal mechanism comprises a high-pressure water pump and a high-pressure water pipe, one end of the high-pressure water pipe is connected with the high-pressure water pump, the other end of the high-pressure water pipe is communicated to a high-pressure air pipe through a tee joint, and the high-pressure air pipe is connected with a manual switching valve whichis arranged between the tee joint and a high-pressure air pump. According to the down-the-hole drill with the dustproof function and the use method thereof, by arranging the dust removal mechanism, the down-the-hole drill has a dust removal function, and dust removal equipment does not need to be independently added; secondly, the high-pressure water pipe is communicated to the high-pressure air pipe, and the original structure of the down-the-hole drill is utilized for aiding dust removal work, so that the down-the-hole drill is compact in overall structure and small in occupied space.

Description

Technical field [0001] The invention belongs to the technical field of rock drilling, and specifically relates to a down-the-hole drill with dust-proof function and a method of use thereof. Background technique [0002] The down-the-hole drilling rig is a percussive rotary drilling rig. Its internal structure is different from ordinary rock drills. Its gas distribution and piston reciprocating mechanism are independent. The front end is directly connected to the drill bit, and the rear end is connected to the drill rod. When rock drilling, the impactor is submerged into the hole, and the piston in the impactor is reciprocated to hit the shank through the gas distribution device, so that the drill bit will impact the rock at the bottom of the hole. The high-speed rotation of the impactor in the hole is realized by a separate rotation mechanism, that is, a motor or a pneumatic rotating device outside the hole, and a drill rod connected to the back end of the impactor.
