Multifunctional accessory control system of excavator and excavator
The invention relates to an engineering machinery control system, and provides a multifunctional accessory control system of an excavator, which comprises an oil supply unit, accessory control valves, a proportional electromagnetic valve group, a controller and an operating mechanism, the accessory control valves comprise a first accessory control valve and a second accessory control valve which are used for connecting accessories, and the operating mechanism is connected with the controller. The first accessory control valve is connected with the first accessory to control working parameters, the second accessory control valve is connected with the second accessory so as to control working parameters, select accessory working modes and control accessory actions, the accessory working modes comprise a one-way accessory mode and a two-way accessory mode, in the one-way accessory mode, the first accessory control valve is connected with the one-way accessory, and in the two-way accessory mode, the first accessory control valve and the second accessory control valve are jointly connected with the two-way accessory. The multifunctional accessory control system of the excavator is a positive flow control system and is small in flow loss, energy-saving in composite action and simple and convenient to operate and control. The invention further provides the excavator.
本发明涉及工程机械控制系统，提供一种挖掘机多功能属具控制系统，包括供油单元、属具控制阀、比例电磁阀组、控制器和操作机构，属具控制阀包括用于连接属具的第一属具控制阀和第二属具控制阀，操作机构连接控制器，以能够控制工作参数、选择属具工作模式和控制属具动作，属具工作模式包括单向属具模式和双向属具模式，在单向属具模式下，第一属具控制阀连接单向属具，在双向属具模式下，第一属具控制阀和第二属具控制阀共同连接双向属具。本发明挖掘机多功能属具控制系统为正流量控制系统，流量损失小，复合动作节能，且操控简单便捷。本发明还提供一种挖掘机。
