Mining excavator loader is mainly composed of driving, digging and conveying three mechanisms and two hydraulic and electrical systems. Through the coordination and cooperation of various parts, the hydraulic, electrical actuator and mechanical transmission mechanism can achieve the required action and complete the operation process.

本机集液压行走，挖掘采集，输送，装车四种性能。其中液压行走功能是通过液压马达驱动前后车轮，液压马达具有前行、后退、自动刹车三种性能；四轮驱动具有着地力，推动力强等特点，挖掘采集功能由机械手完成，机械手具有挖掘、伸臂、装料，卸料性能，大臂可上升、下降，左右回转，挖掘采集的操纵由全液压控制，由六个操作手柄控制，每个手柄控制二个动作，共十二个动作。

This machine has four functions: hydraulic walking, digging, collecting, conveying and loading. Among them, the hydraulic walking function is to drive the front and rear wheels through the hydraulic motor, which has three performances: forward, backward and automatic braking; The four-wheel drive has the characteristics of landing force and strong driving force. The digging and collecting function is completed by the manipulator. The manipulator has the functions of digging, extending arm, loading and unloading. The arm can rise, fall and rotate left and right. The digging and collecting operation is controlled by full hydraulic pressure, and is controlled by six operating handles. Each handle controls two actions, a total of 12 actions.

输送，装车性能由输送机系统完成，其输送架由液压缸控制升降，输送架下降时可将前轮支起，同时输送架前接料口与矿石接触面更紧密，工作时稳定性更强，同时可以集合散料，平整场地。传送带宽度为650mm，传送速度约为5m/秒，传送带由液压马达带动滚筒、使传送机性能更稳定，使用寿命更长。

The conveying and loading performance is completed by the conveyor system. The lifting of the conveyor frame is controlled by the hydraulic cylinder. When the conveyor frame descends, the front wheel can be supported. At the same time, the contact surface between the material receiving port in front of the conveyor frame and the ore is closer, and the stability is stronger when working. At the same time, it can collect bulk materials and level the site. The width of the conveyor belt is 650mm, and the transmission speed is about 5m / s. the conveyor belt is driven by a hydraulic motor, which makes the performance of the conveyor more stable and the service life longer.

整车液压系统由一台15kw电机为动力带动二联高压齿轮泵，液压油通过齿轮泵分别输入壹台多路换向阀内，通过操作手柄实现对各液压装置的控制。

The hydraulic system of the whole vehicle is driven by a 15kw motor to drive a two-way high-pressure gear pump. The hydraulic oil is respectively input into a multi-way directional valve through the gear pump, and the control of each hydraulic device is realized through the operating handle.

整车电器系统采用矿用隔爆型电磁起动器，实现对电机的控制，确保人身和设备。

The electrical system of the whole vehicle adopts the mine flameproof electromagnetic starter to control the motor and ensure the safety of personnel and equipment.

该机动力源为外部引入的工频660（380）V三相交流电源，整机采用一台15kw电机，驱动滚筒采用液压驱动，操作方面只需一人。

The power source is a 660 (380) V three-phase AC power supply. The whole machine uses a 15kw motor, and the driving roller is driven by hydraulic pressure. Only one person is needed for operation.
