Auxiliary hydraulic system of machines and tools and excavator
The invention provides an auxiliary hydraulic system of machines and tools and an excavator, and relates to the technical field of excavating equipment. The auxiliary hydraulic system of the machinesand tools comprises an oil supply device, a main valve, a reversing valve, a hammering and shearing device and a control device. The oil supply device communicates with the main valve. The main valvecommunicates with a rodless cavity of the hammering and shearing device through a first oil way, and the main valve communicates with a rod cavity of the hammering and shearing device through a secondoil way. The reversing valve is located on the second oil way and directly communicates with the oil supply device. The oil supply device, the main valve and the reversing valve are all connected with the control device, and the control device is used for guiding pilot oil of the oil supply device to the main valve and the reversing valve to control the main valve and the reversing valve to reverse. According to the auxiliary hydraulic system of the machines and tools, reversing of the main valve and the reversing valve is achieved through the control device, the auxiliary hydraulic system can be fast switched between all work states, and full electronic control over a hammering mode and a shearing mode is achieved.
本发明提供了一种机具辅助液压系统及挖掘机,涉及挖掘设备技术领域,本发明提供的机具辅助液压系统包括供油装置、主阀、换向阀、锤剪装置和控制装置;供油装置与主阀连通;主阀通过第一油路与锤剪装置的无杆腔连通,主阀通过第二油路与锤剪装置的有杆腔连通;换向阀位于第二油路并与供油装置直接连通;供油装置、主阀和换向阀均与控制装置连接,控制装置用于将供油装置的先导油导向主阀和换向阀,以控制主阀和换向阀换向。本发明提供的机具辅助液压系统通过控制装置实现主阀以及换向阀的换向,可快速在各个作业状态之间切换,实现锤剪模式全电控。
