On impulsion cylinder, the limbers at valve piston front end sprays, along with the increase of ejection water, to the valve piston chamber of piston-cylinder
In valve piston produce thrust backward, thus drive impulsion cylinder pass through helical spline under the effect of freewheel clutch to
Rear rotating shrinking；
When impulsion cylinder drives big piston to be retracted to the end at the big piston intracavity of piston-cylinder, Radix Angelicae Dahuricae (Radix Heraclei Scabridi) reversal valve quilt beyond the Great Wall
The body that is located by connecting backs down, so that the big piston aquaporin with pressure conducting that Radix Angelicae Dahuricae (Radix Heraclei Scabridi) communicates with aquaporin with pressure beyond the Great Wall, makes band setting-out
Spray into big plunger shaft；
When the water pressure with pressure sprayed into is more than the pressure in valve piston chamber, band setting-out promotes forward big piston, drives impact piston
Bar is by helical spline rotation expansion forward under the effect of freewheel clutch；
When big piston moves to the stroke end of big plunger shaft, the reversal valve of big piston cuts out, big piston waterpipe with pressure quilt
Reversal valve blocks, and the water of big piston intracavity discharges piston-cylinder, repeat the above steps by being located at the osculum of the stroke end
Making impulsion cylinder drive hydraulic pressure swivel head to rotate, hydraulic pressure swivel head drives bit bore；
C., when exceeding presetting force value towards the water pressure with pressure of spinning vibration slotting device, setting-out is crossed by three
Leading to separately flows in high-pressure rubber pipe and decompression protection device, excessively after the water inlet of setting-out entrance decompression protection device in relief valve
Pipeline inflow filter in, filter out the setting-out of crossing after mudstone and enter after filter flows out and arrive first the counter balance pocket of control valve,
Setting-out of crossing in counter balance pocket overcomes the pressure that in control spool, compression spring is downward, and the take-off needle-valve band dynamic pressure in valve pool is sliding
Pole upwards take-off, cut somebody's hair under the effect of location spring on the pressure litter after take-off in litter location in pressure litter both sides simultaneously
Slideway draw-in groove position, make the outlet pipeline of pilot-actuated valve turn on, reduce the pressure in counter balance pocket, when in counter balance pocket
Pressure reduce after, what relief valve water inlet conduit flowed into cross setting-out overcomes in pressure releasing valve core pressure release spring to the pressure of plug,
By plug jack-up, make the water inlet of relief valve turn on water return outlet, setting-out is discharged by water return outlet and realizes decompression protection；Therefore
After barrier is got rid of, pulling out litter location and cut somebody's hair, pressure litter drives take-off needle-valve return under the effect of compression spring, it is achieved
Reset work；
D. in drilling process, when the high pressure sealing drilling rod porpoise being exposed at outside boring and whirling vibration stop when,
Then judge that the situation of bit freezing occurs in spinning vibration slotting device, now, open waterpower propulsion system, utilize waterpower propulsion system
Double acting hydraulic cylinder high pressure sealing drilling rod is carried out drawing campaign, make spinning vibration the related drill bit of slotting device break away from bit freezing
Situation, when cutting rock or hard coal seam, needing to open waterpower propulsion system additionally increases to spinning vibration slotting device
Impulsive force.
The method of hydrodynamic force drilling slotting the most according to claim 1, it is characterised in that: described when cutting rock or hard
During coal seam, needing to open waterpower propulsion system additionally increases impulsive force to spinning vibration slotting device.
The method of hydrodynamic force drilling slotting the most according to claim 1, it is characterised in that: the regulator of described employing and
It is serially connected between decompression protection device, or parallel with one another by threeway, then be connected in waterpower propulsion system by threeway.
The method of hydrodynamic force drilling slotting the most according to claim 1, it is characterised in that: described Aquatic product generating apparatus with pressure is
Setting-out generator, emulsion power pack or natural-drop band compressed water generation apparatus, the press water pressure limit that Aquatic product generating apparatus with pressure produces
For 0-150Mpa, optimum working pressure value is 2-100Mpa.
The method of hydrodynamic force drilling slotting the most according to claim 1, it is characterised in that: described drill bit is provided with diamond
Cutting blade and little pick, drill bit periphery is provided with cutting jet water hole, it is achieved band pressure water jet cuts, and described drill bit revolves with hydraulic pressure
Rotary head is integral type or split.
