Weighing system and method of excavator
The invention belongs to the technical field of excavators and relates to a weighing system and method of an excavator. The weighing system comprises a movable arm position sensor, a bucket rod position sensor, an excavator bucket position sensor, an oil pressure sensor and a controller; the movable arm position sensor is arranged at the position of a movable arm of the excavator and electrically connected with the controller; the bucket rod position sensor is arranged at the position of a movable arm of the excavator; the bucket rod position sensor is electrically connected with the controller; the excavator bucket position sensor is arranged at the position of an excavator bucket of the excavator, and the excavator bucket position sensor is electrically connected with the controller; and the oil pressure sensor is arranged on a hydraulic oil cylinder of the movable arm of the excavator. According to the weighing system of the excavator, the excavator is operated to a specific posture after performing excavation; the excavation weight is calculated according to a function relation between the oil pressure of a main oil tank and the excavation weight of the excavator; and thus, weighing system is convenient and practical.
本发明涉及挖掘机技术领域，特别涉及一种挖掘机的称重系统及方法，称重系统包括：动臂位置传感器、斗杆位置传感器、挖斗位置传感器、油压传感器及控制器；动臂位置传感器设置在挖掘机的动臂位置处，动臂位置传感器与控制器电性连接；斗杆位置传感器设置在挖掘机的动臂位置处，斗杆位置传感器与控制器电性连接；挖斗位置传感器设置在挖掘机的挖斗位置处，挖斗位置传感器与控制器电性连接；油压传感器设置在挖掘机的动臂液压油缸。本发明提供的挖掘机的称重系统，通过将挖掘机挖取后运行至特定的姿势，通过主油箱油压与挖掘机挖取重量的函数关系计算出挖取重量，方便实用。
