Detail information on rock drilling rig:
It is a kind of drilling equipment by converting hydraulic energy into mechanical energy.
It consists of impact mechanism, rotating mechanism and water and gas slag discharge mechanism.
The piston is forced to reciprocate at high speed in the cylinder block by differential pressure action,
and the impact bit tail realizes the chisel effect.
The piston and the reversing valve move independently and restrict each other.
Before the piston cavity subjected to normal pressure oil,
the movement of the piston is through the change of directional control valve has been change after the piston chamber pressure and implementation;
The reversing valve is through the piston movement back and forth to open or close the oil signal hole,
in order to change the pressure area of the reversing valve to achieve.
The hydraulic motor provides torque and speed to the bit tail through gear transmission.
When the bit touches the rock, the piston reciprocates to transfer the impact energy to the bit to break the rock through the bit tail
and drill pipe.
The rotary motion of the hydraulic motor delivers the torque and rotation speed to the bit through the gearbox,
the bit tail and the drill pipe to assist the bit in crushing the rock.
The water-air slagging mechanism relies on the external injection joint to flush the water or gas through the drill tail, drill pipe,
drill bit's inner hole or blow air to discharge the impact broken gravel to the hole and assist the impact broken rock.

7. Oil return buffer
1. Piston:The impact energy of the piston acting on the bit shank produces impact breaking effect on rock and other materials.
The impact frequency can be adjusted according to different applications.
2. Reversing valve:Connected to the engine body, reversing valve and piston can be mutually controlled through the principle of stroke feedback, forming a fast running matching system.
3. Energy accumulator: Adding impact flow or absorb excessive pressure to keep the hydraulic system stable
