Current divider 4 is made up of shunt body 18 and the two parts of sprue 19, and the inside of shunt body 18 is provided with two shuntings
Road 13, one is straight channel, and one is inclined flow passage, two shuntings of two runner upper ends respectively with double female fluidic generators 2
Road connects, and the first splitter box 20 is arranged at the bottom of shunt body 18, and inclined flow passage extends to the first splitter box 20, the first 20 pairs of splitter box
Title is provided with two pod apertures 22, and the first splitter box 20 is connected with the two pod apertures 22 respectively；Sprue 19 carries ring to be internal
The cylinder of shape platform, sprue 19 is looped around the bottom of shunt body 18 and forms the second splitter box 21 of annular, second splitter box
21 are also symmetrically arranged with two pod apertures 22, and second splitter box 21 is also respectively communicated with two pod apertures 22, above-mentioned two pairs totally four
Individual pod apertures 22 intersect.The pod apertures 22 of current divider 4 are corresponded with the pod apertures 22 of gland 7.When liquid is penetrated from double mothers
When 2 one branch roads of flow-generator are flowed down, will by inclined flow passage, so as to flow into the corresponding a pair symmetrical pod apertures 22 of gland 7, when
Liquid from another runner flow down when, will by straight channel, coordinate sprue 19 inner flow passage insert the liquid into gland 7 other one
In symmetrical a pair of the pod apertures 22 in side.
Gland 7 is an additional symmetrical ring sector volume cylinder, and with the pod apertures 22 of four equal volumes, four
Pod apertures 22 are communicated with current divider 4 respectively, and its effect is to flow out upper level influent by corresponding pod apertures 22, so that
Make Hydro-efflux Hammer 3 by reciprocating rotary clockwise or counterclockwise with the pressure of liquid.
Hydro-efflux Hammer 3 is a kind of component for the motion that can rotate in a circumferential direction, and its shape is one and clips the symmetrical arc body in both sides
Long-pending cylinder, so, makes Hydro-efflux Hammer 3 have symmetrical arc boss 16, height of its arc boss 16 than central cylinder
Slightly lower, transmission short circuit top has an arc-shaped cavity for accommodating arc boss, four pod apertures of gland respectively with arc-shaped cavity four
Side wall is corresponding, and drilling fluid enters two symmetrical side-walls of arc-shaped cavity by two corresponding pod apertures, promotes liquid
Dynamic hammer rotates round about, Hydro-efflux Hammer is swung back and forth in arc-shaped cavity.I.e. when drilling fluid is symmetrical from a pair of gland 7
Flowed out in pod apertures 22, during into Hydro-efflux Hammer 3 and the symmetrical closing space of the transmission formation of short circuit 5, Hydro-efflux Hammer 3 along one can be promoted
Individual direction rotates, and the impact transmission wall of short circuit 5, Hydro-efflux Hammer 3 stops operating, and causes the closing space shape constituted with transmission short circuit 5
Into building the pressure, liquid backflows.The liquid that backflows forces liquid in double female fluidic generators 2 to change runner, from the symmetrical pod apertures of another pair
22 outflow, promote Hydro-efflux Hammer 3 reverse rotation, and then be rebuffed, build the pressure, feed back, liquid circulation road, so realize transmission short circuit 5 after
And the rotational vibration of drill bit.
On the one hand transmission short circuit 5 accommodates Hydro-efflux Hammer 3, on the one hand plays transmission：The circumference that Hydro-efflux Hammer 3 impacts generation is shaken
The moment of torsion of dynamic and upper drilling string passes to drill bit.Being driven the top of short circuit 5 has the arc-shaped cavity 9 for accommodating arc boss 16, works as drilling well
Liquid from opening flow out when, can flow into the arc boss 16 of Hydro-efflux Hammer 3 with transmission shell constituted closing space when formed build the pressure, push away
Rotating in a circumferential direction for dynamic Hydro-efflux Hammer 3, impacts transmission short circuit 5, and then the drill vibration for driving transmission short circuit 5 to be connect below.
During present invention work, drilling fluid flows into double female ejector devices 2 from the end suitable for reading of housing joint 1.Because occurring attached wall effect
Should, drilling fluid can first concentrate on certain side of runner 13.Assuming that first attached wall is exported liquid in left side runner, through shunt body
18 and the collective effect of current divider sprue 19 shunting after, in the pod apertures 22 left by gland 7 it is symmetrical two opening, enter
Hydro-efflux Hammer 3 and the closing space formation of the transmission formation of short circuit 5 build the pressure.Hydro-efflux Hammer 3 rotates to dead point under the promotion of pressure, hits
Short circuit 5 is driven, causes transmission short circuit 5 to be vibrated to a direction.Move to behind the dead point, closing space pressure constantly rises, bore
Well liquid is returned along along former runner, and liquid runner is returned by double female fluidic generators 2, into the annular groove 11 of housing joint 1, is entered
Current by pass 10, is flowed into inside drill string, and then flow into drill bit by the through hole for being driven side wall of outer shell.Meanwhile, in left side runner shape
Into pressure feedback, the attached wall of drilling fluid is forced in the right runner of double female fluidic generators 2.Closing space fluid pressure is not under the runner of right side
Disconnected rise, forces Hydro-efflux Hammer 3 to be rotated in the opposite sense, and then transmission short circuit 5, drill bit is vibrated in opposite direction.With left runner
Similarly, when Hydro-efflux Hammer 3 rotates to right side runner dead point, the runner formation feedback on right side makes drilling fluid and attached wall is in left side runner.
So move in circles, the circumference for just realizing drill bit is of reciprocating vibration.
