Sawtooth lubricating hydraulic system for excavator and felling machine and control method of sawtooth lubricating hydraulic system
The invention discloses an excavator and felling machine sawtooth lubricating hydraulic system and a control method thereof.In the hydraulic system, an oil suction port of a main pump is connected with a hydraulic oil tank, and an oil outlet of the main pump is connected with oil inlets of a first electromagnetic reversing valve and a second electromagnetic reversing valve; a working oil port of the first electromagnetic directional valve is connected with the motor driving mechanism and used for operating the motor driving mechanism to control the sawtooth motor to drive sawteeth to stretch out or retract; a working oil port of the second electromagnetic directional valve is connected with the serrated motor and is used for controlling the serrated motor to work; the recovery hydraulic oil tank collects leaked oil of the motor driving mechanism and the sawtooth motor, the recovery hydraulic oil tank is connected with the lubricating oil control mechanism, and the lubricating oil control mechanism is used for controlling hydraulic oil in the recovery hydraulic oil tank to drip on the surfaces of sawteeth. Leaked oil of devices such as the sawtooth motor is adopted for lubricating the sawteeth, the service life of the sawteeth is effectively prolonged, and the hydraulic system is simple in structure, convenient to control and capable of saving cost.
本发明公开了一种挖掘机、伐木机具锯齿润滑液压系统及其控制方法,液压系统中,主泵的吸油口与液压油箱相连,主泵的出油口与第一电磁换向阀及第二电磁换向阀的进油口相连;第一电磁换向阀的工作油口与马达驱动机构相连,用于操作马达驱动机构以控制锯齿马达带动锯齿伸出或收回;第二电磁换向阀的工作油口与锯齿马达相连,用于控制锯齿马达工作;回收液压油箱收集马达驱动机构和锯齿马达的泄漏油,回收液压油箱与润滑控油机构相连,润滑控油机构用于控制回收液压油箱内的液压油滴落在锯齿表面。本发明采用锯齿马达等装置的泄漏油对锯齿进行润滑,有效延长了锯齿的使用寿命,且液压系统结构简单,控制方便,节省成本。
