The invention discloses a hydraulic breaking hammer which comprises the components of a drill rod seat, a drill rod, a drill rod front sleeve, a drill rod back sleeve, a cylinder body, a piston, a nitrogen chamber sealing sleeve, a crankcase, a crankshaft, a connecting rod, a connecting rod piston, a motor, an eccentric wheel, a reversing valve, an energy accumulator, a valve plate, etc. One end, which is far from the drill rod, of the piston is dynamically connected with the eccentric wheel though the connecting rod, the crankshaft and the gear. One end of the crankshaft is connected with the motor. A sealed chamber for storing gas is arranged between the piston and the cylinder. The valve plate is mounted on the crankshaft. The hydraulic breaking hammer aims to settle problems of high difficulty in downward pressing a nitrogen explosion hammer, large hydraulic impact, incapability of stopping oil supply from a pump in a stroke period without oil consumption, no enough impact force caused by insufficient flow in a full-hydraulic hammer or a gas-liquid hammer, complicated structure, and large hydraulic impact force.
