Environmental-friendly downhole hammer rock drilling machine

Abstract

The invention relates to an environmental-friendly downhole hammer rock drilling machine. As the existing downhole hammer rock drilling machine is additionally provided with a liquid supply box and a liquid supply system, the liquid can be jetted with compressed air from the chisel bottom of a drop hammer during operation, and the liquid can be water, grout, bentonite or mortar, when water is used as liquid, a hot chisel can be cooled, thus being beneficial to improving abrasion resistance and work efficiency and ensuring the working life to be long, when grout, bentonite or mortar is used as liquid, collapse around a chiseled perforation can be avoided, thus being beneficial to safe production; besides, the dust produced in punching construction process can be effectively inhibited, noise during the punching construction can be greatly reduced, and meanwhile, punching speed can be effectively improved while the water is jetted and discharged with the compressed air, thus having strong practicability.

Description

technical field [0001] The invention relates to a ground drilling construction machine, in particular to an environment-friendly down-the-hole hammer rock drilling rig which arranges a liquid nozzle at the center of the hammer body so that the liquid can be ejected from the bottom of the chisel head simultaneously with compressed air. Background technique [0002] Among the various environment-friendly down-the-hole hammer rock drilling rigs known at present, the chisel head arranged inside the down-the-hole hammer is driven by compressed air to make vertical reciprocating motions and rely on hammering action to drill rock holes. It has existed for a long time: 1. The machine parts are easy to damage and the economy is poor. The heat generated by the impact friction between the chisel head and the rock will increase the surface temperature of the chisel head, which will affect the wear resistance of the chisel head and the effective working life of the chisel head; 2. Dust a...

[0002] Among the various environment-friendly down-the-hole hammer rock drilling rigs known at present, the chisel head arranged inside the down-the-hole hammer is driven by compressed air to make vertical reciprocating motions and rely on hammering action to drill rock holes. It has existed for a long time: 1. The machine parts are easy to damage and the economy is poor. The heat generated by the impact friction between the chisel head and the rock will increase the surface temperature of the chisel head, which will affect the wear resistance of the chisel head and the effective working life of the chisel head; 2. Dust and loud noise will be generated during operation, which will not only pollute the environment, but also endanger the health of the workers; 3. The drilling speed is slow and the safety is poor, not only the overall work efficiency is low, but also prone to collapse around the hole, etc. unsafe situation

Therefore, from the perspective of economy and practicality, it is not ideal.
