Abstract
The invention discloses a mining handheld all-hydraulic drill based on an internal curve motor. The mining handheld all-hydraulic drill comprises a drill body upper shell, a drill body lower shell, an overflow-throttle valve, a holding rod, an adjustment arm, an oil distribution disc, the multi-action internal curve radial hydraulic motor, a speed increaser, a drill rod and a drill bit. High pressure oil enters the multi-action internal curve radial hydraulic motor from an oil inlet of the drill body upper shell through the overflow-throttle valve and the oil distribution disc and pushes a piston in the multi-action internal curve radial hydraulic motor and beams to press to the internal curve surface of a stator, rollers are located on the beams, make direct contact with the internal curve surface of the stator, and interact with the stator to generate axial force so as to push a rotor to rotate, and therefore the drill rod connected with the speed increaser is driven to rotate so as to drive the drill bit to achieve the purpose of drilling. The mining handheld hydraulic drill has the advantages that stress is balanced, the drill holding rod is easy to hold, torque is large, all-hydraulic operation is achieved, speed adjustment and reversing are achieved, and overload protection is achieved.
