Types of Rock Drill Machines:

The pneumatic rock drill drives the piston forward in the cylinder by air compressor, so that drill bit can hit the rock. The impact rod rotates back and forth and forms a circular blast hole. Gas powered rock drill mainly consist of air cylinder-piston assembly, gas distribution device, steel brazed rotary mechanism, control valve and flushing-blowing mechanism.

Diesel rock drill has the advantages of convenient operation, saving time and labor, fast cutting speed and high efficiency. Drilling holes in the rock can be less than 45 ͦ horizontally, and the deepest vertical hole can be up to 6m. Diesel drill can work in high mountains, flat ground, 40 ͦ extreme heat or minus 40 ͦ severe cold area. The drill machine has a wide range of adaptability. It has various functions of splitting, crushing, tamping, shovel and other functions. Internal combustion rock drill is widely used in mining, construction, fire protection, geological exploration, road construction, defense engineering, etc.

Electric rock drill can drill soil layer, foundation pit slope, subgrade soil layer, anchor hole.It often drills holes in water conservancy construction, road construction, and stonework operations. Electric drill also can explore water, gas (methane).

Hydraulic rock drill is a powerful rock drilling equipment, it has high pressure oil as the working medium. Hydraulic rock hammer drill is the ideal supporting equipment for blasting construction. Its performance is far superior to the pneumatic rock drill. The working efficiency of hydraulic drills is 5-10 times than pneumatic drills, but its energy consumption is only 1/3. Hydraulic rock drill machine is an outrigger full hydraulic drill, it can be used with a variety of hydraulic stations. It has the advantages of high drilling speed, low power consumption, light noise, few failures, safety and reliability, simple configuration and convenient movement.
