Load weighing control system and excavator
The invention provides a load weighing control system and an excavator, and relates to the technical field of excavator application. The load weighing control system comprises a first angle sensor, asecond angle sensor, a pressure sensor and a controller. The first angle sensor is arranged on a movable arm pin shaft, measures a first included angle between a movable arm and the vertical directionof the gravity, and sends the first included angle to the controller. The second angle sensor is arranged on a bucket rod, measures a second included angle between the bucket rod and the vertical direction of the gravity, and sends the second included angle to the controller. The pressure sensor is arranged on the movable arm, measures the pressure of a large cavity of the movable arm, and sendsthe pressure of the large cavity of the movable arm to the controller. The controller is connected with the first angle sensor, the second angle sensor and the pressure sensor correspondingly, and calculates the load weight and the total load weight. By calculating the loading weight of a dumper and other vehicles in the working process of the excavator, the time of the weighing link is saved, andthen work efficiency is improved.
本发明提供了一种负载称重控制系统和挖掘机，涉及挖掘机应用技术领域，包括第一角度传感器、第二角度传感器、压力传感器和控制器；第一角度传感器，设置在动臂销轴上，测量动臂与重力竖直方向的第一夹角，并将第一夹角发送至控制器；第二角度传感器，设置在斗杆上，测量斗杆与重力竖直方向的第二夹角，并将第二夹角发送至控制器；压力传感器，设置在动臂上，测量动臂大腔压力，并将动臂大腔压力发送至控制器；控制器，分别与第一角度传感器、第二角度传感器和压力传感器相连接，计算负载重量和负载总重量，通过在挖掘机工作过程中计算出对自卸车等车辆的装车重量，节省称重环节的时间，进而提高工作效率。
