Yn27A Internal Combustion Rock Drill

The internal combustion rock drill is a combination of small gasoline engine, compressor, rock drill from the jackhammer tool.It is suitable for mountains, no power, no wind pressure equipment areas and greater mobility of temporary works. During operation, compressed air from the purge itself of the eyes of rock powder guns. Main applications Turning the swing arm to running-or-stop rotation, the machine can be converted into a breaker or a hammer, for breaking, digging, splitting or ramming. The machine is suited to build of bridge, road, power station, geological exploration etc. Features of rock drill 1.Easy to operate , just turn the handle to make it work. 2. Time and labor saving, Drilling fast and high efficiency. 3.Light Drilling Tools, only 27kgs, easy to carry. 4.Used to drill vertical downward hole(max depth 6m) and and

Summary Advantages: Needless to replace the internals of the engine head, just handle the handle to operate it. Easy to operate. More time-saving and effortless. Drilling faster and more efficient. Have reached the tip-top level of the same field now, and allow to be replaced with the same kind of the domestic products. Applications: Available for drilling, splitting breaking, ramming, shoveling. And widely used in mining, road contruction, quarrying and national defense construction, etc. Wooden crate

1.Introduction of YN27C internal combustion rock drill The YN27C internal combustion rock drill has various functions such as mining, drilling, building construction, geological exploration, cement pavement, asphalt pavement and other functions such as splitting, crushing, compacting and shovel. It is widely used in mining, road construction, quarrying, construction, railway tamping, geological survey, national defense engineering, etc. 2.Features of YN27C internal combustion rock drill You only need to move the handle as required to complete the drilling or crushing operation. The machine is easy to operate, saves time and labor, and has the characteristics of fast cutting speed and high efficiency. The machine has reached the first-class level of similar products and can be completely interchanged with international similar products. The drilling can be vertically downwards, horizontally upwards less than 45°, and vertically drilled up to six meters. The weight of the main machine is only 27 kg. Only one person can operate it. It is easy to carry. It is suitable for areas with high mountains, no power supply, no wind pressure equipment and temporary projects with large mobility. This machine has wide adaptability in both high mountains and flat land, regardless of the extreme heat of 40° or the cold region of minus 40°. This machine adopts export packaging, and all the indicators meet the export standards. This product is exempt from inspection and does not require commodity inspection for export. Since only gasoline needs to be added to work, no other auxiliary equipment is needed. This machine is suitable for mining of various mines such as iron ore, copper mine, nickel mine, lead-zinc mine, gold mine, gemstone mine, granite, bluestone and jade. 3.Parameters of YN27C internal combustion rock drill Host weight: 27kg Engine type: single cylinder air-cooled two-stroke gasoline engine Carburetor type: no float Ignition method: thermistor contactless system Engine displacement: 185 cm³ Engine load speed (measured when chiseling five holes): â?¥2450r/min Drill rod idle speed: â?¥200r/min Shank size drill rod tail: hexagon 22*108mm Deepest hole drilling depth: â?¥6m Fuel tank volume: â?¥1.14L Punching speed: â?¥250mm/min Gasoline and lubricating oil mixing ratio (by volume): 12:1 Spark plug electrode gap: 0.5-0.7mm Fuel consumption rate (measured when chiseling five holes: â?¤0.12L/M Impact energy: â?¥25J Shandong Master Machinery Group specializes in supplying internal combustion rock drills.
