Loader and hydraulic system thereof
The invention relates to a loader and provides a loader and a hydraulic system thereof in order to solve the problem that an existing loader hydraulic system is insufficient in refined operation. The loader hydraulic system comprises a controller, a movable arm oil cylinder, a bucket oil cylinder, a working pump, a steering pump, a steering operation mechanism and an action operation mechanism, the movable arm oil cylinder and the bucket oil cylinder are composed of digital oil cylinders, the steering operation mechanism is used for generating steering electric signals, the action operation mechanism is used for generating action electric signals, the steering pump is connected with a confluence control valve, and a first working oil port of the confluence control valve is connected with the steering mechanism. The second working oil port is in confluence connection with the working pump; the confluence control valve is electrically connected with the controller, and the controller controls the confluence control valve and outputs pulse equivalent signals to stepping motors of the movable arm oil cylinder and the bucket oil cylinder according to the steering electric signals and the action electric signals. According to the hydraulic system, the movable arm oil cylinder, the bucket oil cylinder and even the steering oil cylinder are digital oil cylinders and are directly controlled by the controller, and accurate control is achieved.
本发明涉及装载机,为解决现有装载机液压系统在精细化作业方面的不足的问题,本发明构造一种装载机及其液压系统,其中装载机液压系统包括控制器、由数字油缸构成的动臂油缸和铲斗油缸、工作泵、转向泵、用于产生转向电信号的转向操作机构,用于产生动作电信号的动作操作机构,转向泵与合流控制阀连接,合流控制阀的第一工作油口与转向机构连接,第二工作油口与工作泵合流连接;合流控制阀与控制器电连接,控制器依据转向电信号和动作电信号控制合流控制阀和向动臂油缸和铲斗油缸各自的步进电机输出脉冲当量信号。在本发明中,动臂油缸和铲斗油缸甚至转向油缸采用数字油缸的形式,由控制器直接控制,实现精准控制。
