Description

Technical Field

[0001] The utility model relates to the field of rock drills, in particular to a rock drill with water supply and dust prevention functions. Background Art

[0002] A rock drill is a tool used to directly mine stone. It drills holes in the rock strata to place explosives to blast the rock, thereby completing the mining of stone or other stone projects. In addition, the rock drill can also be converted into a destroyer to break hard layers such as concrete. Rock drills can be divided into four categories according to their power source: pneumatic rock drills, internal combustion rock drills, electric rock drills and hydraulic rock drills.

[0003] The rock drills currently in use are all used to operate in mines or underground rock layers. Due to the special operating scenarios, a large amount of dust will accumulate on the surface of the rock drill, thus affecting the use of the rock drill. Specifically, fine dust will enter the interior of the rock drill and accumulate on the surface of internal components, thereby accelerating the aging of the equipment.

[0004] Patent announcement number CN207879250U describes a rock drill with water supply and dust prevention functions, comprising a rock drill housing, a connecting sleeve, a drill rod, a drill tail and a water injection port, wherein the connecting sleeve is arranged in the rock drill housing and axially arranged, the drill rod is horizontally installed on one end of the connecting sleeve, and the drill tail is horizontally connected to the other end of the connecting sleeve, with beneficial effects: an internal water cavity is formed by the inner surface of the rock drill housing and the water injection port, the sealing member and the outer surface of the connecting sleeve, thereby saving internal space; the flow port provided on the connecting sleeve is conducive to water flow entering the drill rod and forming a water curtain through the liquid outlet, so that the water curtain formed in the early stage of drilling can surround the dust in the drill hole and then flow out with the water; in addition, the filtering device and the discharge hopper are provided to avoid blockage and internal impurities in the equipment during long-term use, thereby achieving a better dust prevention effect.

[0005] The above-mentioned patent announcement number is CN207879250U rock drill, which uses a flowing water curtain to block dust. This will undoubtedly increase the personal safety of construction workers, because some rock drills are electric, and the flowing water source may cause leakage of equipment, etc., which may cause injuries to people at the construction site.
