The monostable fluidic nozzle centerline in double control road, and it is smaller with vertical angle；Different two of diameter are provided with bit body
Blind hole, be connected respectively to two of the monostable fluidic in double control road outlets, wherein big-diameter blind hole is connected with big nozzle, small blind hole and
Small nozzle is connected.
Before block stamp and drill bit collision, drilling fluid is entered double by the monostable fluidic nozzle in double control road and two control roads
Control the monostable fluidic in road.Because the size in two control roads is different and left and right wall and the monostable fluidic in double control road
The distance of nozzle centerline is different so that drilling fluid can stablize attached wall to left wall face, through excessive nozzle rinse bottom hole；Work as block stamp
When being collided with drill bit, right control road is plugged, into double control road monostable fluidic drilling fluid from left control road
Attached wall to right wall and enters the small nozzle of drill bit under fluid thrust effect, and then producing pressure in drill bit internal increases sharply and in hole
Bottom forms pulsing jet.In the impact several times of block stamp and drill bit, separation process, right control road in double control road cycle therewith
Property folding, into the drilling fluid of the monostable fluidic in double control road, high frequency switches immediately, produces high-frequency pulse jet flushing hole bottom.
The nozzle quantity being connected with big-diameter blind hole and small blind hole is multiple.
The beneficial effects of the invention are as follows：
The block stamp that high-frequency reciprocating moves is regarded as " control valve ", impact moment is completed in the monostable fluidic in double control road
Fluid switches in diameter different fluid interchannel and then forms frequency pressure pulses in shaft bottom；The design increase of asymmetric double control road
Fluid inflow-rate of water turbine, ensure that drill bit entrance is in low-pressure state before shock；Pressure increase is connect in block stamp and bit hits
Complete, impact process will not be adversely affected after touch；The design makes full use of arteries and veins on the premise of block stamp motion is not influenceed
The good characteristic of pulsed waterjet cleaning effect, when being effectively improved deep hole rapid drilling landwaste be easy to accumulation the problem of, reduce repetition
Crush and improve drilling life of bit.Fluid passage switching simultaneously also changes jet eject position, makes up to a certain extent
The defects of down-hole hammer button bit rotating speed is low, injection fluid coverage is small, further enhances landwaste elimination effect；Due to
The unexpected increase of pressure after shock, block stamp backhaul response are also accelerated, improve frequency of impact to a certain extent, improve brill therewith
Enter efficiency.
