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.

礦用裝載機(jī)的工作性能及原理：

Working performance and principle of mine loader:

①這種裝載機(jī)集液壓行走，挖掘采集，輸送，裝車四種性能。其中液壓行走功能是通過液壓馬達(dá)驅(qū)動前后車輪，液壓馬達(dá)具有前行、后退、自動剎車三種性能。

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.

②四輪驅(qū)動具有著地力，推動力強(qiáng)等特點，挖掘采集功能由機(jī)械手完成，機(jī)械手具有挖掘、伸臂、裝料，卸料性能，大臂可上升、下降，左右回轉(zhuǎn)，挖掘采集的操縱由全液壓控制，由六個操作手柄控制，每個手柄控制二個動作，共十二個動作。

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輸送，裝車性能由輸送機(jī)系統(tǒng)完成，其輸送架由液壓缸控制升降，輸送架下降時可將前輪支起，同時輸送架前接料口與礦石接觸面更緊密，工作時穩(wěn)定性更強(qiáng)，同時可以集合散料，平整場地。傳送帶寬度為650mm，傳送速度約為5m/秒，傳送帶由液壓馬達(dá)帶動滾筒、使傳送機(jī)性能更穩(wěn)定，使用壽命更長。

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.

由于礦用裝載機(jī)的液壓系統(tǒng)由一臺15kw的電機(jī)為動力帶動二聯(lián)高壓齒輪泵，液壓油通過齒輪泵分別輸入壹臺多路換向閥內(nèi)，通過操作手柄實現(xiàn)對各液壓裝置的控制。整車電器系統(tǒng)采用礦用隔爆型電磁起動器，實現(xiàn)對電機(jī)的控制，確保人身和設(shè)備。

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.
