Abstract:
The present application provides a working machine, a hydraulic control system, and a control method for a breaking hammer. The control method for a breaking hammer comprises: in response to the fact that a switch of a breaking hammer is triggered, the working machine enters a breaking mode, and a relay sends a working signal to a controller; and on the basis of the working signal received by the controller, the controller sends a first signal to a power unit so as to supply oil to the breaking hammer, and a timing unit records a duration of the working machine entering the breaking mode. According to the control method for a breaking hammer of the present application, the relay is used for sending the working signal, the controller is used for sending the first signal and a second signal, and the timing unit records the duration of the working signal of the relay and uses same as a working time of the breaking hammer, such that an actual working duration of the breaking hammer can be accurately recorded. The controller can unify a decision and control the power unit to achieve the purpose of controlling an oil path to supply oil to the breaking hammer, so as to play a role in supplementing oil.
