Description

Technical Field

[0002] Hydraulic rock drills are specialized equipment used in mining, metallurgy and other industries. They are used to drill holes in high-hardness, brittle materials such as ores and rocks, or to assemble taphole machines. They have the characteristics of high impact power, high energy utilization and easy automation control.

[0003] After searching, a Chinese patent with publication number CN216008376U discloses a dust-proof hydraulic rock drill. The key technical point of the patent is that it solves the problem that when the hydraulic rock drill is in operation, the rock layer is repeatedly impacted, and the rock layer is partially broken to form blastholes. The broken rock layer will generate a large amount of dust. The dust is raised and inhaled by the construction workers, which has an adverse effect on the health of the construction workers and may even cause pneumoconiosis accidents.

[0004] However, in the above scheme, it was found that after long-term use, the dust-proof components would be damaged under the action of impact force. At this time, the dust-proof components need to be replaced and maintained in time. The above scheme cannot replace and maintain them, which affects their use. In addition, during dust-proof operations, due to the vibration of the rock drill, the above scheme cannot make the dust-proof components always fit the working position. When the dust-proof components float up and down, some dust will still be emitted into the air, and the dust-proof effect is poor.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
