If you want to learn more, please visit our website internal combustion DTH drill rig.
INTRODUCTION:
HJG-B series open-air blast hole drilling rig
is a combustion engine driven crawler-type hydraulic drilling rig developed by our company, adopting self-propelled hydraulic track chassis with favorable mobility and equipped with high-power hydraulic motor, heavy hydraulic drill boom and high air pressure DTH Hammer. The use of drilling rig HJG-B140 mainly covers strip mining, road construction and rock-drilling process in the field of water-power engineering. It is a down-the-hole drilling rig specially designed for open mine, stone pit and construction industry.HJG-B series open-air blast hole drilling rig adopts diesel engine. Hydraulic oil pump unit offers power to hydraulic motor moving, turn-around, propulsion and lifting, and angle orientation of oil cylinder, etc. When drill is working, only the down-the-hole hammer consumption of fuel is saved by 40% to 50%.
ADVANTAGES:
1,All hydraulic control, low purchase cost
Hoist & feed system and rotary head are both driven by hydraulic power with easily operating. Its drilling can use low or high pressure compressing air, saves 1.5 times air volume as contrasted with the drill by air-driven. It can reduces the total cost of drilling.
2. High efficiency, energy saving.
The drilling rig power is less than the drilling rig by air-driven,can save more than 10 liter in one working hour, supply more turning torque and feeding & hoisting power with hydraulic driven motor. It is better used for hammer of 90-165mm to smash and flake rock.
3. Good stability.
Succinct mechanical arm, decreasing the sliding frame joint, when drilling blast hole the drill can have better stability.
4. Favorable agility and flexibility.
The drilling rig is a combustion engine driven hydraulic crawler drilling rig, adopting self-propelled hydraulic track chassis and equipped with high-power hydraulic motor, can have better agility and performance through the floating joint of framework.
5. Engine
Cummins 100 hp engine special for industry, to drive hydraulic pump and motor which provide strong power for all actions of the machine.
6. Rotary head
Hydraulic rotary motor supply strong power, maximum rotary torque can reach 4500NM, equipped with enforced absorber, eliminate the back force from the hammer effectively to protect the motor and speed reduction box.
7. Hoist & feeding system
Using strong linkage chain system, driven by hydraulic motor, supplying 15000N lifting force, it can rapidly feed and lift to save assistant time and improve the drilling efficiency.
8. Control board
Control handle centralized control, easily operating, the operator can operate the drill at the side of the drill. It improves the safe factor.
9. Undercarriage
High-power hydraulic motor has great moving driving force and high grade-ability to pull the air compressor. It is operated flexibly and is convenient for working. The crawler undercarriage floats within the range of 15°tilting gauge, which is suitable for the construction in cragged field. The crawler which is used for project and machinery is firm and durable.
10. Air filter and fuel tank
Two-stage air filter can filter over 90% of dusts in the air inflow and discharge them automatically with no cleaning, which can effectively reduce the abrasion of engine, prolong the lifetime, enhance the efficiency and be used in various severe working conditions.160 liter fuel tank ensures one working day supplying.
