The invention discloses an efficient rock drilling machine comprising a support. The lower end face of the support is fixedly connected with a motor, and the output end of the motor is fixedly connected with one end of a rotating rod. The efficient rock drilling machine is simple in structure; by switching on an external power source, the motor is started, a roller moves downwards, a drill bit moves periodically in an up-down reciprocating mode while rotating, and the drilling rock crushing effect is achieved; meanwhile, a mounting box is fixed to a bearing through supporting rods and does notrotate along with a long rod, and a rotating disc rotates along with the long rod; under the effect of limiting rods, mounting tubes wobble to pull connecting rods continuously so as to enable secondinserting rods to conduct outward vibration; and therefore, the rock crushing effect is achieved, the rock crushing efficiency is improved, and the working efficiency is improved.
