Overview
The integral hydraulic down-the-hole drill is widely used for blast hole drilling in open-air projects, such as metallurgy, mines, construction materials, railway, hydro-power constructions, national defense constructions and earthworks. As one of most advanced integral hydraulic down-the-hole drill in domestic market, it is equipped with an efficient high pressure down-the-hole drilling system to facilitate the blast hole drilling with high precision and efficiency. Internationalized sourcing, optimizing design of computer, power matching, development and application of load bearing system help to realize a full power matching of the power system from power to pump, and then to load bearing, which enables to reduce the energy consumption for the machine and ensure a best performance and a high reliability can be achieved.
Down-the-hole Drill Rig Characteristics
Excellent performance, high efficiency, energy saving, and environmental friendliness
--Its highly reliable running unit allows a fast running and rapid lifting can be obtained, which
significantly improves the productivity;
--It is equipped with an automatic disassembly and assembly unit for the drill rod and a multiple-rod drill rod storage to fully save human resources;
--The automatic anti-rod blocking unit is to realize automatic lifting of the rod in case of getting stuck, effectively protects the drilling system;
--The hydraulic and pneumatic systems are driven by a separate power system, respectively, having significant energy saving effect;
--It adopts vortex and laminar dust removal system to fully reduce dust pollution and reach good effect of environmental protection;
--The operating and monitoring system are highly integrated and have low operating cost.
Floating traveling chassis
--Adopts floating traveling chassis, and is suitable for rough construction sites.
Multiple-function hydraulic drill boom
--It has multiple functions, and is suitable for construction drilling with casing, pilot pre-splitting and anchor rod reinforcement;
--The angle of drill frame is adjustable, and can meet requirements for drilling at multiple directions;
--The drilling boom has wide working range, multi-hole can be achieved after one trip positioning, helps to improve the working efficiency;
--Compared with traditional drill, the impact of extended drill boom, vibration caused by percussion hammer and slagging dust on overall stability and operating environment is greatly reduced to extend the service life of the machine and improve its drilling precision.
Comfortable and safe operating
--High-end and practical driving cab with beautiful appearance, safe and comfortable operating space;
--Equipped with an air-conditioner, adjustable elastic damping seat and anti-smashing & anti-rollover protection measures;
--Real-time monitoring working performance and operating parameters.
Compact structure and reasonable arrangement
--The drilling, air supply and power systems are integrated to form a compact structure and allow the machine to work flexibly;
--It adopts modular design to facilitate convenient maintenance.
Reliable quality
--Strong and fuel-efficient power system;
--Internationally preferred sourced key hydraulic parts;
--World-class percussion hammer and drilling system;
--Special chassis made of high- strength steel.
