To movement.Cylinder body 7 is placed in the first center tap 5, forms cavity of resorption input channel between cylinder body 7 and the first center tap 5 inwall
7b, cavity of resorption input channel 7b passes through two O-ring seals sealings.Cylinder body 7 is divided into epicoele 32 and cavity of resorption by one-piece piston 8
34, it is provided with becket 36 between one-piece piston 8 and cylinder body 7 inwall.Cylinder body 7 and cylinder cap 14 pass through three being evenly distributed
Individual mode connects for screw, inner cylinder body 7 and cylinder cap 14 pass through the second back-up ring 9 and the second O-ring seal 10 seals, inner cylinder body 7 and cylinder cap 14
Between be provided with pad 35.Spreading weldering thickness respectively in the piston rod of one-piece piston 8 and the wall of cylinder cap 14 friction part is 2mm
Cemented carbide powder to form piston rod wearing layer 15 and cylinder cap wearing layer 16, piston rod wearing layer 15 and cylinder cap wearing layer 16
Surface roughness be not more than 3.2.Between cylinder cap 14 and one-piece piston 8, dynamic sealing, car seal are realized by Che Shi sealing
It is made up of fabroil axle sleeve 11, the 3rd O-ring seal 12 and foot shape slip ring 13.One-piece piston 8 bottom and block stamp 18 pass through
Threaded, block stamp 18 is placed in the second center tap 17, and the second center tap 17 top is threaded connection with the first center tap 5,
Second center tap 17 bottom and the 3rd center tap 22 are threaded connection.Four ball assemblies have been evenly arranged it along block stamp 18 circumference
19, away from block stamp 18 lower surface 20cm～25cm, this example is 20cm to ball assembly 19, and ball assembly 19, by ball blend stop 19a, rolls
Pearl 19b, ball base 19c form.It is interference fit between ball base 19c and block stamp 18, in ball base, place 5～10 balls
19b, is 5 in this example, ball 19b is limited in ball base 19c by ball blend stop 19a, and ball blend stop 19a is welded on rolling
On pearl seat 19c.It is set with hammering block 20 in 3rd center tap 22, be provided with hammering block flowing hole 20a and the 4th in hammering block 20 and cross circulation
Road 20b, hammering block 20 is provided with spline 20c.Hammering block 20 and the 3rd center tap 22 splined connecting portion have circumferentially been evenly arranged four
Individual spin assembly 21, by catch 21a, spin 21b, spin seat 21c forms spin assembly 21, and spin seat 21c top is provided with slot,
Catch 21a is placed in spin seat 21c slot, and spin 21b is contained in spin seat 21c.Spiral shell is passed through with lower contact 23 in hammering block 20 lower end
Stricture of vagina connects, 23 times termination drill bits of lower contact.
It is arranged symmetrically two the first flow channels 24 in top connection 1, in the first center tap 5, be arranged symmetrically two the second mistakes
Circulation road 26, has been arranged symmetrically two the 3rd flow channels 31 in cylinder body 7.First flow channels 24, the second flow channels 26,
It is logical within impacter that 3rd flow channels 31, hammering block flowing hole 20a and the 4th flow channels 20b collectively constitute drilling fluid
Road.Disc spring 2b is in compressive state after installing it is ensured that flow divider 2a closes when pump amount is low, and drilling fluid is directly entered without shunting
First center tap 5.When pump amount increases, when drilling fluid is applied to power on flow divider 2a and is more than disc spring 2b elastic force, flow divider 2a to
Lower movement, the first flow channels 24 are opened, and unnecessary drilling fluid passes through the first flow channels 24 and realizes shunting, and effective protection is impacted
Device.Different disc spring 2b decrements being set for different operating modes, thus adjusting the SHUNT state of flow divider, realizing constant current
Amount.
When impacter works, the drilling fluid being flowed into by top rod enters impacter through top connection 1, if flow divider 2a
Institute's stress is less than disc spring 2b pretightning force, and drilling fluid is directly entered bistable fluidic 6, if flow is sufficiently large, compresses disc spring 2b, real
Now shunt, a part of drilling fluid is through the first flow channels 24, the second flow channels 26, the 3rd flow channels 31, hammering block flowing hole
20a, the 4th flow channels 20b and lower contact 23 enter drill bit；Another part drilling fluid enters bistable jet by flow divider 2a
Element 6, drilling fluid produces attached wall effect after entering bistable fluidic 6 it is assumed that first attached wall, on the right side of bistable fluidic 6, bores
Well liquid enters cavity of resorption 34 by right side the 3rd flow channels 31, and promotion one-piece piston 8 is up, and adjusting rod 33 is connect with energy storage leaf spring 30
Compressed energy-storage leaf spring 30 after touch.One-piece piston 8 goes upward to stroke and produces water hammer finally, and feedback signal makes drilling fluid simultaneously
By being switched on the right side of bistable fluidic 6 on the left of bistable fluidic 6, drilling fluid enters epicoele from left side the 3rd flow channels 31
32, promote one-piece piston 8 and block stamp 18 descending.Energy storage leaf spring 30 resilience after the descending beginning of block stamp 18, resilience force acts on tune
On pole 33, promote block stamp 18 descending.Block stamp 18 come downwards to stroke finally when impact hammering block 20, impulsive force transmitted by hammering block 20
To drill bit.Now feedback signal makes the attached wall of jet on the right side of bistable fluidic 6, and drilling fluid enters cavity of resorption 34.Impacter works
During low pressure chamber drilling fluid through bistable fluidic 6 emptying road enter the 3rd flow channels 31, then flow through hammering block mistake
Discharge orifice 20a, the 4th flow channels 20b and lower contact 23 impact shaft bottom, enter annular space.
