Description

Technical Field

[0001] The utility model belongs to the technical field of slag discharging of rock drills, and particularly relates to a device for improving the slag discharging device of a rock drill converted by high-pressure water. Background Art

[0002] Slag discharging is a necessary process for a rock drill to drill holes in rocks. When the rock drill drills holes, the front drill tool needs to have functions of impact, rotation and slag discharging. During drilling, the crushed slag needs to be discharged in time. At present, the methods are air slag discharging and low-pressure water slag discharging. Due to the very low air pressure and water pressure, the ability to discharge the crushed slag is limited. High-pressure water can generate a certain cutting ability along with the rotation of the drill bit during slag discharging, reduce the temperature of the drill bit and timely discharge the crushed slag, and the working efficiency is remarkable.

[0003] Therefore, it is necessary to provide an improved technical solution aiming at the deficiencies of the above-mentioned existing technologies. Summary of the Utility Model
