connecting rod 14 of lower engages axle is installed in fairlead 12, and connecting rod 14 part for lower engages axle is positioned at the inside of housing 1, and connecting rod 14 another part of lower engages axle is positioned at the outside of housing 1.The connecting rod 14 that lower contact 13 is arranged on lower engages axle is positioned on the outer end outside housing 1.One end of upper engages axle 2 is spline housing 7 structure, and the spline axle head 8 of lower engages axle is inserted in the spline housing 7 of engages axle 2.Upper spring 6 is sleeved on the spline housing 7 of engages axle 2 and the spline axle head 8 of lower engages axle.Lower spring 9 is installed on the connecting rod 14 of lower engages axle, and one end of lower spring 9 is attached on one end of fairlead 12, and the other end of lower spring 9 is attached on the end face of plunger 22 of lower engages axle.The central authorities of upper engages axle 2 are provided with axial slurry channel 3, and the radial direction of upper engages axle 2 is provided with radial slurry channel 4, and this radial slurry channel 4 is connected with described axial slurry channel 3.As depicted in figs. 1 and 2, housing 1 is laid with the axial slurry channel 21 of housing in circumference 23, the axial slurry channel 21 of this housing engages axle 2 radial slurry channel 4 corresponding position on described is provided with mud inlet 5, the axial slurry channel 21 of this housing engages axle 2 spline housing 7 corresponding position on described is provided with slurry outlet 20, the axial slurry channel 21 of this housing is provided with mud entrance 18 in plunger 22 corresponding position of described lower engages axle, the corresponding position that the axial slurry channel 21 of this housing is equipped with lower spring 9 at the connecting rod 14 of described lower engages axle is provided with mud delivery outlet 16, lower engages axle central authorities are axially arranged with axial mud output channel 11, the connecting rod 14 of lower engages axle is provided with radial mud output channel 10 being equipped with lower spring 9 part radial direction, radial mud output channel 10 and the lower engages axle axis of centres of the connecting rod 14 of this lower engages axle interlink to mud output channel 11, the axial slurry channel 21 of housing is provided with block 19 between slurry outlet 20 and mud entrance 18.Effect of shaking is rushed preferably for reaching, the axial slurry channel 21 of housing that described housing 1 is laid with in circumference 23 is three to eight, corresponding with the axial slurry channel 21 three to eight of described housing, the radial slurry channel 4 of described upper engages axle 2 is three to eight, and the axial slurry channel 21 of the housing of described three to eight engages axle 2 radial slurry channel 4 corresponding position on described is equipped with mud inlet 5.For reducing the moving resistance of connecting rod 14 in fairlead 12, the inwall of described fairlead 12 is provided with drag reduction groove 1.For reducing plunger 22 moving resistance within the case 1, plunger 22 external surface of described lower engages axle is provided with drag reduction groove 2 17.Rush in vibrating device at above-mentioned helicoid hydraulic motor, when upper engages axle 2 is rotated, lower engages axle is followed upper engages axle 2 by the spline axle head 8 be inserted in upper engages axle 2 spline housing 7 and is rotated, when radial slurry channel 4 mud inlet 5 rotated on the axial slurry channel 21 of the housing be provided with housing 1 circumference 23 of upper engages axle 2 communicates, high-pressure slurry in the axial slurry channel 3 of upper engages axle 2 and radial slurry channel 4 enters the axial slurry channel 21 of housing from the mud inlet 5 of the axial slurry channel 21 of housing, then high-pressure slurry enters the cavity between housing 1 and upper engages axle 2 spline housing 7 and lower engages axle spline axle head 8 from the slurry outlet 20 of the axial slurry channel 21 of housing, at this moment high-pressure slurry promotes the plunger 22 of lower engages axle away from upper engages axle 2, lower spring 9 is compressed simultaneously, instantly the plunger 22 of engages axle is when the mud entrance 18 that the axial slurry channel 21 of housing is corresponding with plunger 22, high-pressure slurry enters the axial slurry channel 21 of housing from mud entrance 18, flow out from the mud delivery outlet 16 of the axial slurry channel 21 of housing again, the connecting rod 14 radial mud output channel 10 and the axial mud output channel 11 that finally enter lower engages axle are discharged, achieve the motion of lower engages axle away from upper engages axle 2 like this.Along with the rotation of upper engages axle 2, when the radial slurry channel 4 of upper engages axle 2 rotates to the position that the mud inlet 5 on the axial slurry channel 21 of the housing be circumferentially with housing do not communicate, because high-pressure slurry cannot enter in the axial slurry channel 21 of housing, therefore the plunger 22 of lower engages axle cannot be promoted away from upper engages axle, at this moment original position is returned to by the lower spring 9 compressed, lower engages axle is pushed away nearly upper engages axle 2, achieve the movement of lower engages axle close to upper engages axle like this.When the rotation 360 ° of upper engages axle 2, the mud inlet 5 on the axial slurry channel 21 of housing is connected with the radial slurry channel 4 of upper engages axle 2 or closes several times successively, thus under realizing, engages axle rushes the several times that shake.The rotation of above engages axle 2 is 130 revs/min is example, and the axial slurry channel 21 of housing that housing 1 is laid with in circumference 23 is eight, the radial slurry channel 4 of upper engages axle 2 is eight, article eight, the axial slurry channel 21 of housing is equipped with mud inlet 5 in upper engages axle 2 radial slurry channel 4 corresponding position, when the rotation 360 ° of upper engages axle 2, eight times are connected or closed to mud inlet 5 on the axial slurry channel 21 of housing with the radial slurry channel 4 of upper engages axle 2 successively, thus realize eight punchings and to shake motion.When the rotation of upper engages axle 2 is 130 revs/min, realizes punching per minute and to shake motion 1040 times, be i.e. 130 × 8=1040 beat/min.As can be seen from above, along with upper engages axle 2 drives the rotation of lower engages axle, lower engages axle may be made higher the rushing of frequency relative to upper engages axle 2 and to be shaken motion.Rush in vibrating device at above-mentioned helicoid hydraulic motor, due to only containing housing 1, upper engages axle 2, lower engages axle, upper spring 6, lower spring 9, fairlead 12 and lower contact 13, therefore relative to existing planet ratchet-type structure, structure is simple.To shake motion owing to adopting hydraulic moving mode to produce punching simultaneously, compared with the frictional force produced during existing planet pawl wheel, greatly reduce, therefore not only long service life, maintenance cost are low, and improve the performance of rotation, reduce energy consumption.

With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on manual, must determine its technical scope according to right.
