已有的单斗式装载机工作过程的自动控制方法不能保证铲斗充分装满,也不能降低机器工作机构上的动力。根据本方法测定铲斗的铲入力,此力从斗臂经连杆传到铲入力的发送器上,并将所得到的信号传给接通信号用的提升机构的滚筒接触器上。下图所示为铲切过程自动化的装载机远距离控制系统图。装在斗臂连杆下面的铲入力发送器ДУ_1和ДУ_2用于控制铲入力及操纵电磁铁接触器ПК_1和ПК_2,它是用来控制提升机构的左右两个滚筒。按压操纵台上的按纽就能借助于继电器PП_1和PП_2完成远距离控制滚筒。为了减少远距离控制电路中的导线
The existing automatic control method of the work process of the single bucket loader cannot guarantee that the bucket is fully filled, nor can it reduce the power on the working mechanism of the machine. According to this method, the scooping force of the bucket is measured, and this force is transmitted from the arm via the connecting rod to the sender of the scooping-in force, and the obtained signal is transmitted to the roller contactor of the lifting mechanism for the switch-on signal. The figure below shows the loader remote control system diagram for automated cutting process. The shovel force transmitters ДУ_1 and ДУ_2 installed under the arm link are used to control the shoveling force and manipulate the electromagnet contactors ПК_1 and ПК_2, which are used to control the left and right rollers of the lifting mechanism. By pressing the buttons on the console, remote control of the rollers can be accomplished with the aid of relays PП_1 and PП_2. To reduce the wires in the remote control circuit
