A hydraulic resonant breaking hammer is described that includes a hydraulic driving system, a vibration exciter, a control system, a linkage mechanism and a breaking hammer head. The hydraulic driving system includes a hydraulic motor, an electric-control hydraulic distributing valve, a hydraulic pump and an engine. The vibration exciter includes a box and at least one group of eccentric wheels. The control system includes a sensor, a microcomputer controller and the electric-control hydraulic distributing valve. The linkage mechanism includes a machine frame, a guide rail and a damper spring. The disclosure solves the problems of the existing engineering breaking devices, such as low efficiency, high noise, serious damages to the driving excavator caused by the reaction of an impact force and incapability of breaking large rocks.
