Loader lifting anti-spillage control system and method
The system comprises a bucket, a movable arm and a tipping bucket cylinder connected with the bucket, the tipping bucket cylinder is connected with a variable pump through a main valve, the main valve is connected with a pilot control device, the main valve is connected with an oil tank through a second overflow valve and a third overflow valve, and the variable pump is connected with a pump displacement control device. The variable pump is also connected with a valve group control system of the movable arm; the system further comprises a controller, the input end of the controller is connected with a handle, a movable arm angle sensor and a bucket angle sensor, and the output end of the controller is connected with a pilot control device and a pump displacement control device. According to the material scattering prevention control system and method for lifting of the loading machine, in the lifting process, the bucket side cutting board is gradually parallel to the angle of the ground, namely, the bucket side cutting board is located at the horizontal position in the half period of time after lifting, the angle difference is eliminated, and therefore the problem that many materials are scattered is solved; and in the lifting process, materials are not scattered, more materials can be loaded and unloaded, and the production rate of single cycle operation is improved.
一种装载机举升防撒料控制系统及方法，包括铲斗、动臂以及与铲斗连接的翻斗缸，翻斗缸通过主阀连接有变量泵，主阀连接有先导控制装置，主阀通过第二溢流阀和第三溢流阀连接油箱，变量泵连接有泵排量控制装置，变量泵还连接有动臂的阀组控制系统；还包括控制器，控制器的输入端连接有手柄、动臂角度传感器和铲斗角度感器，控制器的输出端连接有先导控制装置和泵排量控制装置。本发明的装载机举升防撒料控制系统及方法，在举升过程中，让铲斗侧刀板逐渐的与地面的角度平行，即让铲斗侧刀板在举升后半段时间处于水平位置，消除该角度差，从而解决较多的物料洒落问题；举升过程中，不撒料，可装卸更多的物料，提升了单次循环作业的生产率。
