Handle control system and excavator
The embodiment of the invention provides a handle control system and an excavator, and relates to the field of engineering machines. The handle control system comprises a first reversing valve, a first handle, a control valve, an electromagnetic reversing valve, a controller and an adjusting switch, the first reversing valve is provided with a first valve port, the first handle is used for openingor closing the first valve port, the control valve is provided with a first guide port and a second guide port, the electromagnetic reversing valve is provided with a first valve position and a second valve position, the controller is used for controlling a valve element of the electromagnetic reversing valve to be at the first valve position or the second valve position so as to achieve switching between the first state and the second state, at the first state, the first valve port communicates with the first guide port, at the second state, the first valve port communicates with the secondguide port, the adjusting switch is electrically connected with the controller, the adjusting switch is used for enabling the controller to control the valve element of the electromagnetic reversing valve to be at the first valve position or the second valve position, and the first handle is used for controlling different actions of a preset part under the first state and the second state.
本发明实施例提供了一种手柄控制系统和挖掘机，涉及工程机械领域，该手柄控制系统包括第一换向阀、第一手柄、控制阀、电磁换向阀、控制器以及调节开关，第一换向阀设置有第一阀口，第一手柄用于打开或关闭第一阀口，控制阀设置有第一先导口和第二先导口，电磁换向阀设置有第一阀位和第二阀位，控制器用于控制电磁换向阀的阀芯处于第一阀位或第二阀位，以在第一状态和第二状态之间切换，在第一状态下，第一阀口与第一先导口连通，在第二状态下，第一阀口与第二先导口连通，调节开关与控制器电连接，调节开关用于使控制器控制电磁换向阀的阀芯处于第一阀位或处于第二阀位，第一手柄用于在第一状态和第二状态下分别控制预设部件的不同动作。
