Excavator main valve, excavator hydraulic system and excavator
The invention belongs to the field of excavators and discloses an excavator main valve, an excavator hydraulic system and an excavator, the excavator main valve comprises a multi-way valve group, the multi-way valve group comprises a first multi-way valve provided with a first oil inlet and a second multi-way valve provided with a second oil inlet, and the first multi-way valve comprises a breaking hammer valve plate; the second multi-way valve is provided with an inner bypass oil way led out of the second oil inlet. And the external breaking valve is connected with the inner bypass oil way and is used for controlling the pressure oil of the inner bypass oil way to be conducted and driving a breaking hammer of the excavator to work. The excavator hydraulic system comprises an excavator main valve. The first main pump is used for pumping oil towards a first oil inlet of the multi-way valve group; the second main pump is used for pumping oil towards a second oil inlet of the multi-way valve group; and the breaking hammer is respectively connected to the breaking hammer valve plate and the external breaking valve through oil ways. The external crushing valve is small in size and can be connected to a multi-way valve group through bolts, so that the size of a main valve is small, pipeline arrangement is convenient, oil supply modes are diversified, and the flexibility of crushing control is improved.
本申请属于挖掘机领域并公开了一种挖掘机主阀、挖掘机液压系统和挖掘机，挖掘机主阀包括多路阀组，包括设有第一进油口的第一多路阀和设有第二进油口的第二多路阀，第一多路阀包括破碎锤阀片，第二多路阀设有从第二进油口引出的内旁通油路；以及外置破碎阀，与内旁通油路相连并用于控制内旁通油路的压力油导通并驱动挖掘机的破碎锤工作。挖掘机液压系统包括挖掘机主阀；第一主泵，用于朝向多路阀组的第一进油口泵油；第二主泵，用于朝向多路阀组的第二进油口泵油；破碎锤，分别油路连接至破碎锤阀片和外置破碎阀。外置破碎阀的体型小，可通过螺栓连接到多路阀组上，使得主阀体积较小，管路布置方便，而且供油方式多样化，提升破碎控制的灵活性。
