Sliding sleeve, by along the screw-cap in axial sliding in a manner of be mounted on the screw-cap in, and one end with it is described after
There are gaps between connector；
Branch sleeve is coaxially connected with the other end of the sliding sleeve, and is used for jointed rod.
Preferably, the shock absorber part is helical spring or coaxial concatenated rubber ring.
Preferably, the slip joint is equipped with external screw thread, be equipped in the transit joint in the slip joint
The matched internal thread of external screw thread, the transit joint are threadedly coupled with slip joint.
Preferably, being connected by spline slide between the slip joint and described sleeve pipe.
Preferably, being connected by spline slide between the screw-cap and the sliding sleeve.
Preferably, the sliding sleeve is equipped with external screw thread, it is equipped with and outer spiral shell on the sliding sleeve in the branch sleeve
The matched internal thread of line, the branch sleeve are threadedly coupled with sliding sleeve.
Hydraulic vibration churn drilling tools provided by the utility model, by drill bit or tup and punching caused by the touching of stone body
Load is hit, transit joint and coupled slip joint is passed to first, vibration damping is transferred vibrations to further through slip joint
On device, so that vibration is obtained buffering and weaken.Since there are gaps, vibration to be obtained to this between rear joint and the end of sliding sleeve
To buffering, only small vibration just passes to branch sleeve and drilling rod up, effectiveness in vibration suppression clearly, so as to avoid vibration
Influence to drilling machine work efficiency extends the service life of equipment, additionally it is possible to reduce noise pollution.
