Described hydraulic oil outlet is communicated with the hydraulic oil inlet of the hydraulic breaking hammer of excavator.
Further, described pilot mechanism comprises:
Return spring seat, its one end is fixedly connected with valve rod through after the through hole be located on valve body;
Return spring, its one end is fixed on described valve body, and its other end is fixed on described return spring seat;
Valve end cap, one end that its one end and described valve body install described return spring seat is sealedly and fixedly connected, and in described return spring seat and described return spring being located at, described valve end cap is provided with guide oil hand-hole.
Further, described guide oil hand-hole is communicated with the hydraulic oil outlet of the pioneer pump of excavator.
Preferably, described valve rod is Step Shaft, and described intake chute is the reducing section on described valve rod, is provided with sealed member between the inwall of the part on described valve rod outside reducing section and described valve body.
Further, the quantity of described hydraulic oil inlet is two, and be respectively the first hydraulic oil inlet and the second hydraulic oil inlet, described first hydraulic oil inlet is communicated with the hydraulic oil outlet of the front pump of hydraulic shovel, and described second hydraulic oil inlet is communicated with the hydraulic oil outlet of the rear pump of hydraulic shovel.
Preferably, described sealed member is O type circle.
Separately, valve body of the present utility model, valve end cap are revolving structure.
The beneficial effects of the utility model are:
The hydraulic oil of at least two pumps collaborates the large hydraulic oil of output flow through converging valve, improves quartering hammer single-impact energy, improves quartering hammer frequency of impact; Energy-conservation fuel-efficient, during single oil pump feed operation, excavator throttle is large, and during utility model works, excavator throttle is much smaller.
