Auxiliary adjusting system, excavator and excavating equipment
The embodiment of the invention provides an auxiliary adjusting system, an excavator and excavating equipment, and relates to the field of engineering machinery. The auxiliary adjusting system comprises a first connecting pipe and a first pilot overflow valve arranged on the first connecting pipe. One end of the first connecting pipe is used for communicating with a hydraulic pump, the other end of the first connecting pipe is used for communicating with a preset accessory, and the first pilot overflow valve is used for limiting the pressure value of hydraulic oil flowing from the hydraulic pump to the preset accessory. By means of the auxiliary adjusting system, the pressure value of the hydraulic oil flowing to the preset accessory can be more accurate, and therefore normal operation ofthe preset accessory is achieved.
本发明实施例提供了一种辅助调节系统、挖掘机及挖掘设备，涉及工程机械领域，该辅助调节系统包括第一连接管以及设置在第一连接管上的第一先导溢流阀，第一连接管的一端用于与液压泵连通，第一连接管的另一端用于与预设属具连通，第一先导溢流阀用于限制从液压泵流向预设属具的液压油的压力值。该辅助调节系统能够使得流向预设属具的液压油的压力值更加准确，以实现预设属具的正常作业。
