YN27 Inter Combustion Gasoline Rock Drill for Mine Drilling
The internal combustion drill is a tool used to directly extract stone. It drills holes in the rock formations so that they can be put into explosives to blow up the rock to complete the excavation of stone or other stonework. In addition, the rock drilling machine can be changed into a breaker, used to break the hard layer of concrete.

Equipment Introduction
The internal combustion rock drill is a drilling machine with fuel combustion as its driving force, and is a hand-held rock-drilling tool composed of small gasoline engine, compressor and rock drilling machine. Mainly used for drilling down, horizontal and up to less than 45 ° hole, replace a few parts, can be changed to crusher or tamping machine, used for a variety of shovel chisel, crushing, digging, splitting and ramming work. Since the machine has its own power, the production of compressed air to blow the hole, it is particularly suitable for high mountains, no power, no pressure gas equipment areas and large liquidity of temporary works. Widely used in Open-pit mining, excavation of frozen soil, road construction, cable laying and water conservancy.
Introduction of YN27 Inter Combustion Gasoline Rock DrillYN27 Inter Combustion Gasoline Rock Drill is a very efficient rock drilling machine, composed of gasoline engine, air pump, rock drill.
It adapts to these outside situations without water and electronic power. Meanwhile it is a hand- held drill, during operation, rock power is blown away by the compressed air produced by the machine itself.Technical Parameters of YN27 Inter Combustion Gasoline Rock Drill

Working principle:
Internal Combustion rock drill is a kind of new rock drilling machine powered by small power internal combustion engine (two-stroke gasoline engine), which is suitable for field operation without power supply and air compressor. According to the needs of the work, internal combustion rock drills in addition to rock drilling operations, generally equipped with more than 10 kinds of tools (such as grinding wheel, picks, spades, shovel, etc.), can be broken, shovel chisel, digging, splitting, ramming and so on operations.
