YT28 Rock drill the use of a wider scope, it is suitable for hard or harder in the (f = 8 ~ 18) of the rock drill hole horizontal or inclined direction, but also vertically upward to drill bolt holes on the roof. Inch hole is generally Φ34 ~ 45 millimeter, Drilling and effective depth of up to 5 meters.
The machine can tunnel cross-section according to the size and type long-winded FT160BC legs, FT160BD Short legs supporting the use of gas can also be mounted on cars or diamond drilling rack use.
The machine is equipped with FY200B-type injector, operating time can provide self-lubricating, its Outside the use of transparent polycarbonate shell material, easy to observe the oil surface, regulate oil, rock drilling machine at work to ensure good lubrication.
Works:
YT28-type rock drill to use compressed air as a driving force to promote the Pistons reciprocating motion. Stroke, when, Pistons impact drill with chisel rock fragments; return trip, Pistons lead solder with a certain rotation angle, continuous shocks, turning so that brazing with Round-shaped carved into the rock hole.
Features:
Operating mechanism to focus, start a flexible, gas-water interaction, use and maintenance easy; noise, vibration small, energy-saving high efficiency, long life wearing parts, blowing hole cleaning ability, and high reliability.
