Reversal valve 6.1 is 2/2-way reversal valve.
As further improvement of the invention, solenoid directional control valve 6.5 is a 2/2-way reversal valve.
It is improved as of the invention further, drill boom multi-way valve 9 includes multiple hydraulic pilot formula multi-way valves and multiple straight
Control formula multi-way valve is connect, liquid oil sources comes from hydraulic control constant pressure pump 2.
Start driving motor, the electromagnetic coil of solenoid directional control valve 6.5 is powered.
（1）When only drill boom acts
Through damping port 6.6 to 6.3 supply pressure of overflow valve oil, 6.3 overflow of overflow valve, oil pressure relief is transferred to hydraulic control constant pressure pump 2
2 hydraulic control mouth of hydraulic control constant pressure pump, that is, the oil pressure relief of overflow valve 6.3 defines the operating pressure of hydraulic control constant pressure pump 2.Overflow valve 6.3
Oil pressure relief set according to maximum working pressure needed for drill boom oil cylinder, so when only drill boom acts, hydraulic control constant pressure pump 2
Operating pressure fully meets the requirement of drill boom action.
（2）Only rock drill percussion action when
For impacting selector valve 3.1 and be operated in HI high impact position.
The pressure oil of hydraulic control constant pressure pump 2 is through impacting selector valve 3.1, the first damping port 3.3, the second check valve 3.10 to the second
Overflow valve 3.7,3.7 overflow of the second overflow valve, oil pressure relief signal are transferred to 4.2 hydraulic control mouth of hydraulic control pressure reducing valve through shuttle valve 3.2, subtract
4.2 decompressed pressure of pressure valve is set as high pressure, rock drill high-frequency percussion at this time.Meanwhile second the oil pressure relief of overflow valve 3.7 also pass
It is handed to third pilot operated directional control valve 6.1 so that third pilot operated directional control valve 6.1 is operated in the second operating position, and two actuator ports are protected
Hold conducting.
Since the 4th pilot operated directional control valve 6.4 is operated in the first operating position at this time, two actuator ports are held on, and
6.1 liang of actuator ports of third pilot operated directional control valve are held on；Since 6.3 oil pressure relief of the 5th overflow valve is higher than third overflow valve
6.1 oil pressure reliefs, so pressure oil of the hydraulic control constant pressure pump 2 through third damping port 6.6 is from 6.1 overflow of third overflow valve；Third is overflow
The oil pressure relief of stream valve 6.1 is transferred to the hydraulic control mouth of hydraulic control constant pressure pump 2 so that the operating pressure of hydraulic control constant pressure pump 2 meets rock drilling
The percussion action requirement of machine.
（3）When drill boom and rock drill impact act simultaneously
For impacting selector valve 3.1 and be operated in HI high impact position.
During drill boom multichannel valve events, shuttle valve group 8 can sense the control pressure and manual reverse of direction of pilot handle 7.1,7.2,7.3
Wherein maximum pressure is transferred to the hydraulic control mouth of pilot operated directional control valve 6.4 so that pilot operated directional control valve by the pressure of multi-way valve working hole
6.4 commutate and are operated in the second operating position, and two actuator ports of the 4th pilot operated directional control valve 6.4 are closed, such 5th overflow valve
6.3 overflow alarm is transferred to the hydraulic control mouth of hydraulic control constant pressure pump 2, and the operating pressure of hydraulic control constant pressure pump 2 is set in high pressure, to meet
The requirement of drill boom action.
Pressure oil is transferred to the hydraulic control mouth of pilot operated directional control valve 3.9 by shuttle valve group 8 simultaneously so that pilot operated directional control valve 3.9 commutates
And the second operating position is operated in, the two actuator ports conducting of the first pilot operated directional control valve 3.9；The pressure oil warp of hydraulic control constant pressure pump 2
Selector valve 3.1, the first damping port 3.3,3.10 to the second overflow valve 3.7 of the second check valve are impacted, the through pilot operated directional control valve 3.9
Two operating positions are to third overflow valve 3.8, since the oil pressure relief of third overflow valve 3.8 is less than the second overflow valve 3.7, so pressure
Power oil is transferred to 4.2 hydraulic control mouth of hydraulic control pressure reducing valve, pressure reducing valve from 3.8 overflow of third overflow valve, oil pressure relief signal through shuttle valve 3.2
4.2 decompressed pressures are set as low pressure, at this time the low impact of rock drill, flow-reduction needed for rock drill, 2 output flow of hydraulic control constant pressure pump
It reduces.
Also that is, when drill boom and rock drill impact act simultaneously, the setting pressure of hydraulic control constant pressure pump 2 is improved to meet drill boom
Driving requirement, while it is automatic reduce rock drill surge, reduce rock drill needed for flow, avoid the occurrence of high-pressure high-flow
Situation prevents driving motor from overloading.
The present invention is also applied on rock drilling or the drilling device using hydraulic gate or hydraulic rock power head.
