Excavator breaking hammer control system
The invention discloses an excavator breaking hammer control system. The excavator breaking hammer control system comprises a first variable pump, wherein an oil outlet of the first variable pump is connected with a breaking hammer through a first oil supply pipeline; a first control valve is arranged on the first oil supply pipeline; an oil outlet of a second variable pump is connected with the breaking hammer and a hydraulic oil tank through a first branch and a second branch; a second control valve is arranged on the second branch; control ends of the first variable pump, the second variable pump and the second control valve are respectively connected with oil outlets of a first electromagnetic valve, a second electromagnetic valve and a third electromagnetic valve; a working oil port of a pilot valve is connected with the control end of the first control valve through a pilot pipeline; the pilot pipeline is provided with a main pressure sensor; the main pressure sensor is electrically connected to an input end of a controller; and an output end of the controller is electrically connected with control ends of the first electromagnetic valve, the second electromagnetic valve and the third electromagnetic valve. According to the excavator breaking hammer control system, efficient work of the breaking hammer is realized through constant-flow control of the breaking hammer, meanwhile, the oil consumption is reduced, and the debugging difficulty of the breaking hammer is reduced.
本发明公开了一种挖掘机破碎锤控制系统，包括第一变量泵，第一变量泵的出油口通过第一供油管路连接破碎锤，第一供油管路上设有第一控制阀，第二变量泵的出油口通过第一支路、第二支路连接破碎锤、液压油箱，第二支路上设有第二控制阀，第一变量泵、第二变量泵、第二控制阀的控制端分别连接第一电磁阀、第二电磁阀、第三电磁阀的出油口，先导阀的工作油口通过先导管路连接第一控制阀的控制端，先导管路设有主压力传感器，主压力传感器电连接到控制器的输入端，控制器的输出端电连接第一电磁阀、第二电磁阀、第三电磁阀的控制端。本发明通过对破碎锤定流量控制实现破碎锤高效工作并同时降低油耗，降低了破碎锤调试难度。
