Land leveler shovel blade control system, control method and land leveler
The invention discloses a grader shovel blade control system and method and a grader, and belongs to the field of electromechanical control of engineering machinery, and the grader shovel blade control system comprises a structure main body, a hydraulic control module and an electrical control module. A controller of an electrical control system receives following control switch signals, slope calibration knob signals and left and right fork locking oil cylinder travel switch signals, and reads left and right lifting oil cylinder displacement sensor signals; corresponding signals are sent to a scraper knife left-right lifting oil cylinder, a scraper knife swing oil cylinder floating balance valve, a left-right fork stop reversing valve and a scraper knife left-right lifting oil cylinder reversing valve which influence the posture of the structure body, the posture of the structure body is adjusted, scraper knife gradient calibration is completed, and a scraper knife action following mode is started. According to the following mode, one scraper knife lifting oil cylinder is adjusted to act, the other scraper knife lifting oil cylinder is adjusted in a following mode, and the slope of the scraper knife is not changed. The difficulty of scraper knife leveling and scraper knife gradient control is simplified, operation is convenient and easy, and the working efficiency is improved.
本发明公开了一种平地机铲刀控制系统、控制方法及平地机，包括结构主体、液压控制模块和电气控制模块三部分，属于工程机械机电控制领域。电气控制系统的控制器接收跟随控制开关信号、坡度标定旋钮信号和左右叉子止动油缸行程开关信号，并读取左右提升油缸位移传感器信号之后，发送对应的信号至影响结构主体姿态的铲刀左右提升油缸和铲刀摆动油缸浮动平衡阀、左右叉子止动换向阀和铲刀左右提升油缸换向阀，对结构主体的姿态进行调整，完成铲刀坡度标定，进入铲刀动作跟随模式。跟随模式即调整一支铲刀提升油缸动作，另一支铲刀提升油缸跟随调整，但铲刀坡度不变。本发明简化了铲刀调平和铲刀坡度控制难度，操作方便简单，提高了工作效率。
