The mine loader is mainly composed of three mechanisms: driving, excavating and conveying, and two hydraulic and electrical systems. Through the coordination and cooperation of each part, the specified actions are realized by hydraulic and electrical actuator and mechanical transmission mechanism to complete each operation process. Their working principle is not complex in terms of working performance.

矿用装载机的工作性能及原理：

Working performance and principle of mine loader:

①这种装载机集液压行走，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。

① This loader has four performances: hydraulic walking, excavation, collection, transportation and loading. The hydraulic traveling function is to drive the front and rear wheels through the hydraulic motor, which has three performances: forward, backward and automatic braking.

②四轮驱动具有着地力，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。

② The four-wheel drive has the characteristics of strong ground force and driving force. The excavation and collection function is completed by the manipulator. The manipulator has the functions of excavation, arm extension, loading and unloading. The boom can rise, fall and rotate left and right. The operation of excavation and collection is controlled by full hydraulic pressure and controlled by six operating handles. Each handle controls two actions, a total of 12 actions.

③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。

③ 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 is lowered, the front wheel can be supported. At the same time, the material receiving port in front of the conveyor frame is closer to the ore contact surface, which has stronger stability during operation. At the same time, it can collect bulk materials and level the site. The width of the conveyor belt is 650mm and the conveying speed is about 5m / s. the conveyor belt is driven by a hydraulic motor to make the performance of the conveyor more stable and the service life longer.

由于矿用装载机的液压系统由一台15kw的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。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。

As the hydraulic system of the mine loader is powered by a 15kw motor to drive the double high-pressure gear pump, the hydraulic oil is respectively input into a multi-channel directional valve through the gear pump, and the control of each hydraulic device is realized through the operating handle. The electrical system of the whole vehicle adopts mine flameproof electromagnetic starter to control the motor and ensure the safety of personnel and equipment.
