Rock Drill Machine

Rock drills are tools used to directly mine stone. It drills blastholes on the rock formations to place explosives to blast the rocks to complete the mining of stone or other stonework. In addition, the rock drill can also be used as a breaker to break down hard layers such as concrete. Rock drills can be divided into four categories according to their power sources: pneumatic rock drills, internal combustion rock drills, electric rock drills and hydraulic rock drills.

Pneumatic Rock Drills 
The pneumatic type drives the piston forward in the cylinder with compressed air, so that the steel is drilled and rocked, which is the most widely used.
Electric Rock Drills 
The electric type is driven by the electric motor through the crank-link mechanism to impact the steel hammer and hit the rock. The powder discharging mechanism is used to discharge the stone chips, and the internal combustion type utilizes the principle of the internal combustion engine to drive the piston to impact the steel brazing and to hammer the rock through the explosive force of the gasoline. Applicable to construction sites without power supply and air supply.
Hydraulic Rock Drills 
The hydraulic type relies on hydraulic pressure to impact the steel through the inert gas and the impact body to hammer the rock. When the impact mechanism of these rock drills is in the return stroke, the rotation mechanism of the steel is forced by the rotating mechanism to make the position of the drill head continue to slash the rock. Through the explosive force of the diesel fuel, the piston is impacted on the steel brazing, so that the impact and rotation are continuously continually, and the stone chip is discharged by the powder discharging mechanism, and the blasthole can be chiseled. As one of the important engineering equipments, hydraulic rock drills are indispensable in the construction of mines, highways and buildings. However, while the rock drill industry is constantly developing, the domestically produced hydraulic rock drills are still inefficient, and some structures and parts have a short service life. The shortcomings such as large vibration and low energy transfer efficiency are not apparent in the absence of vibration damping devices in the working process.
Internal Combustion Rock Drills 
The internal combustion rock drill does not need to replace the internal parts of the machine head, just move the handle as required to operate. It has the advantages of convenient operation, more time saving, labor saving, fast cutting speed and high efficiency. Holes in the rock can be drilled vertically down, horizontally upwards less than 45° and vertically down to the deepest hole up to six meters. Whether it is in high mountains or flats, whether it is working in a hot area of 40° or a cold area of minus 40°, this machine has a wide range of adaptability.
The internal combustion rock drill has the functions of mining, drilling, building construction, cement pavement, tarmac and other cracking, crushing, tamping, shovel and other functions. It is widely used in mining, construction, fire fighting, geological exploration, road construction, quarrying, Construction, defense engineering, etc.
