Behind the gap that high-pressure fluid entrance outer shell 15 rear drive rotating vane 10 and lobe stator 11 are formed, by high-pressure spray
Physical efficiency is converted into mechanical energy, and meanwhile, the fluid flowing through blade flows into rotary valve mandrel 7, high-speed rotary through flowing hole 19
The vane-spindles 9 turning drives the rotary valve mandrel 7 that is attached thereto to rotate so that the high pressure in rotary valve mandrel 7 becomes a mandarin window and low
Extrude stream window can at a time align with the high and low pressure window on rotary valve valve casing 5, now, cavity V1, V2 will with turn
The high pressure of Valve spindle 7 become a mandarin window connection, and cavity V3, V4 by with rotary valve mandrel 7 low extrusion stream window connect.Meanwhile,
High-pressure fluid enters mandrel inner chamber by the flowing hole 19 in rotary valve mandrel 7, because nozzle 6 is positioned at rotary valve mandrel 7 high and low pressure
Between window, therefore due to the effect of nozzle 6, forming pressure reduction at nozzle 6 upper and lower end, being arranged above high pressure, lower orientation is low
Pressure, fluid is entered into overlapped in cavity V1, the V2 cooperatively forming by impact head 4 and piston cylinder 26 by the high pressure window that becomes a mandarin, by
The axially staggered distribution of high and low pressure window in rotary valve mandrel 7 so that adjacent two cavitys V3, V4 and low pressure window and
The low stream window that extrudes connects simultaneously, and now, impact head 4 starts to rotate under the effect of two chamber fluid pressure differences and clashes into piston cylinder
26, impact is passed to by drill headgear 1 by piston cylinder 26 and rotary valve valve casing 5；This ballistic work is by being passed by drill headgear 1
It is delivered on drill bit, make drill bit produce circumference impact.
When rotary valve mandrel 7 continues to rotate, the high pressure window of subsequent time rotary valve mandrel 7 will rotate to neighboring chambers V3, V4,
V3, V4 cavity and the high pressure window on rotary valve valve casing 5 and the high pressure in the rotary valve mandrel window that becomes a mandarin is connected, with this with
When, cavity V1, V2 of previously having connected with high pressure window are by the low pressure of low pressure window and rotary valve mandrel 7 with rotary valve valve casing 5
Going out to flow window connection, now, high pressure chest originally becomes low pressure chamber, and low pressure chamber originally has then become high pressure chest, punching
Tapping the head and 4 starting to rotate and clash into piston cylinder 26 in the opposite direction under the effect of two chamber fluid pressure differences, this ballistic work acts on and is subject to
On drill headgear 1 and make it rotate in the opposite direction.The vane-spindles 9 of High Rotation Speed drives rotary valve mandrel 7 quickly to rotate,
The high and low pressure window making neighboring chambers is quickly alternately opened, and so repeatedly, impact head 4 moves back and forth and clashes into piston cylinder
26, and impulsive force is transferred to by drill headgear 1, finally high-frequency percussion work(is produced to drill bit.
The utility model is owing to taking above technical scheme, and it has the advantage that the utility model can be at drilling process
In drive impact head reciprocating percus-sion piston cylinder by the high-pressure fluid of alternation and impact is transferred to is formed high frequency by drill headgear rushes
