Rotary drilling rig power head with damping mechanism

The utility model relates to the technical field of rotary drilling rigs, and discloses a rotary drilling rig power head with a damping mechanism, which comprises a fixing rod, and a mounting groove is arranged at the bottom of the fixing rod. The utility model discloses a rotary drilling rig power head with a damping mechanism. A telescopic rod and a damping spring are arranged; a good damping effect can be achieved on the power head; the instantaneous load increase of the drill rod under the condition that the power head encounters a hard stratum or a stone layer and the like is avoided; meanwhile, other parts can be protected; the service life of the power head and other parts is longer; corrugated hose, a good protection effect can be achieved on the movable rod; by arranging the sleeve rod, the compression spring and the inner rod, the effect of stabilizing the power head can be achieved, the power head can stably work, the damping effect can be improved, the power head and otherparts can be well protect
