Rotation so as to drive the splined shaft 26 being connected with the screens of spline housing 29 rotation then drive drill bit rotation work；
Change annexation in series or in parallel between motor 1 and motor 2 23 by control valve 241, so as to full
The different working environment of foot；
Piston 15 carries out ballistic motion in middle cylinder body 13 and realizes changing for the direction of motion of piston 15 by changement 11
Become, promote piston 15 to be moved up in middle cylinder body 13 when in the bottom high pressure chest of cylinder body in being flowed into when hydraulic oil 13, work as piston
15 when being moved to certain position, and the oil duct of the middle inside of cylinder body 13 connection changement 11 is opened, so as to promote valve body 112 to overcome bullet
The resistance of spring 114 is subjected to displacement, the oil circuit and the top of middle cylinder body 13 when valve body 112 is moved to certain position on changement 11
High pressure chest communicates, and now the direction of motion of piston 15 changes, and does at a high speed impact downwards against splined shaft 26, produces kata-rocks
The impact energy of stone is so as to realize impact work, and now valve body 112 completes a percussion action due to the resistance reset of spring 114
Circulation；
By accumulator 1 and accumulator 3 17 can more effectively increase piston 15 hitting power and absorption in cylinder body 13
The reaction force of internal hydraulic pressure oil；
The phenomenon of drilling rod can be blocked unavoidably when hydraulic rotary-percussive hammer drill is lifted up process, now beaten by counter
Mechanism 3 can solve this problem, and when kelly phenomenon occurs, hydraulic oil can promote when entering in anti-crust breaking body 31 and instead beat piston
33 move the shoulder 261 for holding splined shaft 26 upwards so that piston 15 is impacted when splined shaft 26 produces vibrations to overcome dead man
Kelly phenomenon；
The reaction force of the anti-internal hydraulic pressure of crust breaking body 31 oil is absorbed by accumulator 2 35；
This hydraulic rotary-percussive hammer drill is by the stroke of the regulating piston 15 of reversal valve 12 so as to realizing the frequency of impact of piston 15
Regulation meets to tackle various complicated execution conditions.
Although the illustrative embodiment of the utility model is described above, in order to the art
Technical staff is it will be appreciated that the utility model, but the utility model is not limited only to the scope of embodiment, to this technology
For the those of ordinary skill in field, as long as long as the utility model that various change is limited and determined in appended claim
In spirit and scope, all are using the innovation and creation of the utility model design in the row of protection.
