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(guò)液壓馬達(dá)驅(qū)動(dòng)前后車輪，液壓馬達(dá)具有前行、后退、自動(dòng)剎車三種性能；四輪驅(qū)動(dòng)具有著地力，推動(dòng)力強(qiáng)等特點(diǎn)，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(gè)操作手柄控制，每個(gè)手柄控制二個(gè)動(dòng)作，共十二個(gè)動(dòng)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.

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(shí)可將前輪支起，同時(shí)輸送架前接料口與礦石接觸面更緊密，工作時(shí)穩(wěn)定性更強(qiáng)，同時(shí)可以集合散料，平整場(chǎng)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(dòng)滾筒、使傳送機(jī)性能更穩(wěn)定，使用壽命更長(zhǎng)。

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.

整車液壓系統(tǒng)由一臺(tái)15kw電機(jī)為動(dòng)力帶動(dòng)二聯(lián)高壓齒輪泵，液壓油通過(guò)齒輪泵分別輸入壹臺(tái)多路換向閥內(nèi)，通過(guò)操作手柄實(shí)現(xiàn)對(duì)各液壓裝置的控制。

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.

整車電器系統(tǒng)采用礦用隔爆型電磁起動(dòng)器，實(shí)現(xiàn)對(duì)電機(jī)的控制，確保人身和設(shè)備。

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.

該機(jī)動(dòng)力源為外部引入的工頻660（380）V三相交流電源，整機(jī)采用一臺(tái)15kw電機(jī)，驅(qū)動(dòng)滾筒采用液壓驅(qū)動(dòng)，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.
