As the improvement of technique scheme, described Connection Block front end is provided with supplementary oil cylinder, and the core bar of described supplementary oil cylinder is articulated with described compensation frame to promote to compensate frame pitch rotation.
As the further improvement of technique scheme, described bent plate is crescent shape, and convex position is towards bearing.
Further, the hinging pin shaft two ends of described principal arm and Connection Block, connecting rod and Connection Block are provided with draw-in groove, snap in limited location clamp in described draw-in groove, and described spacing clamp is fixedly connected on the surface of hinge hole.
Further, described spacing clamp is screwed the surface being connected to hinge hole.
The beneficial effects of the utility model are: compared with traditional structure, lower oil cylinder pushing principal arm pitch rotation of the present utility model, strengthened the luffing angle of Connection Block by the coaxially hinged bent plate of the core bar with upper cylinder and connecting rod when upper cylinder extends, thus drive compensation frame and drill bit to turn to negative angle, increase the luffing angle of down-the-hole drill; Connecting rod also add the pitch rotation speed of Connection Block, completes the pitching motion of down-the-hole drill fast, speeds up the work.The utility model is rational in infrastructure, greatly can increase luffing angle and pitch rotation speed that down-the-hole drill compensates frame.
