CY-R120V Drill Raise Boring machine is a design of highly efficient drilling equipment to change the backward technology in the construction of lifting tanks and artificial construction which is widely used in the construction of the dark well of coal , the user can select the drilling machine due to the drill diameter and depth .Drilling machine can not only drill A coal bunker coal mine ventilation shafts, all kinds of dark, well, pay well, but also is widely used in metallurgy, chemical and other mines in the rock drilling, expanding role.
CY-R120V Drill Raise Bore drilling machine with hydraulic drive, new models, compact structure, high degree of mechanization, convenient transportation, easy to operate to meet the requirements of the environment in the explosion-proof operation, drill adaptable to meet different geological conditions of mining construction requirements can greatly improve the speed of well construction, and construction safety, hole quality, construction and low cost.
1.Hydraulic cylinder,high efficiency.
2.Wheel walking mechanism,very convenient for transport and adjusting the drilling rig level.
4.Diesel engine with electric starter,convenient and reduce the labor itensity.
5.Equipped with BW 250 mud pump.
|Nominal raise diameter||3000mm|
|Drilling Rod diameter||60mm|
|Drill rig moving stroke||450mm|
|Spindle max. pressure force||90KN|
The raise bore drilling machine’s main drive through the power water swivel pass to drilling tools, lead the pilot hole bits or reamer cutter to rotation. Under the drilling pressure, the pilot tricone bits or reamer cutter to impact, extruding and cut the rock, make the rock broken. The broken rock debris will be eliminated from the drilling hole by positive cycle water or mud on pilot hole drilling. The reamer drilling’s rock debris will be fall on level tunnel directly, and use the loader to load on transport machine or transport vehicles to removed from the drop rock debris place.
The pilot hole drilling is the top-down drilling, and the broaching drilling is down-up drilling.
