The underground loader is mainly used to shovel soil, sand, lime, coal and other bulk materials, as well as light shovel excavation of ore and hard soil. Because the mining loader has the advantages of fast operation speed, good mobility and light operation, it has developed rapidly and become the main machinery in earthwork construction.

井下開采空間狹小、通風(fēng)條件差，井下裝載機(jī)以保障工作效率為前提，在機(jī)械結(jié)構(gòu)設(shè)計(jì)上采用雙翻斗缸設(shè)計(jì)，活動(dòng)靈活，其他相關(guān)工作裝置更是經(jīng)計(jì)算機(jī)優(yōu)化設(shè)計(jì)，使其結(jié)構(gòu)更合理，具有強(qiáng)勁的鏟掘力和較短的作業(yè)循環(huán)時(shí)間，工作效率更高；優(yōu)化散熱器結(jié)構(gòu)，采用五葉片不等角風(fēng)扇，系統(tǒng)采用鋁制散熱器，增加了散熱面積，優(yōu)化整個(gè)系統(tǒng)的進(jìn)出風(fēng)道設(shè)低發(fā)動(dòng)機(jī)水溫和液壓系統(tǒng)的油溫，熱平衡溫度更低，提高了整機(jī)效率，可以適應(yīng)更高井下的特殊工作環(huán)境溫度；基于井下環(huán)境問題考量。

The underground mining space is narrow and the ventilation conditions are poor. On the premise of ensuring the working efficiency, the underground loader adopts the double tipper cylinder design in the mechanical structure design, which is flexible. Other relevant working devices are optimized by computer, so that their structure is more reasonable, with strong digging force, short operation cycle time and higher working efficiency; Optimize the radiator structure, adopt five blade unequal angle fan, and the system adopts aluminum radiator to increase the heat dissipation area. Optimize the inlet and outlet air duct of the whole system, set low engine water temperature and oil temperature of hydraulic system, lower heat balance temperature, improve the efficiency of the whole machine, and can adapt to higher special working environment temperature under the well; Based on the consideration of downhole environmental problems.

在設(shè)計(jì)上還對排放裝置做了一系列結(jié)構(gòu)改進(jìn)與創(chuàng)新，發(fā)動(dòng)機(jī)排出的廢氣通過兩級過濾，保證在空氣流通不暢的空間內(nèi)工人作業(yè)的健康問題。巷道專用裝載機(jī)，采用大功率四缸柴油機(jī)，功率儲(chǔ)備大，動(dòng)力強(qiáng)勁。整機(jī)外觀大方、穩(wěn)重。超低車身設(shè)計(jì)，狹窄低矮巷道作業(yè)難題。液壓油路加裝3級過濾，保證液壓系統(tǒng)清潔、通暢、可靠，延長各液壓元件的使用壽命。后置排煙過濾系統(tǒng)，保證了巷道作業(yè)場所的空氣清潔。

A series of structural improvements and innovations have also been made in the design of the emission device. The exhaust gas discharged by the engine is filtered through two stages to ensure the health of workers in the space with poor air circulation. The special loader for roadway adopts high-power four cylinder diesel engine with large power reserve and strong power. The appearance of the whole machine is generous and stable. The ultra-low body design solves the difficult problem of narrow and low roadway operation. The hydraulic oil circuit is equipped with three-stage filtration to ensure that the hydraulic system is clean, unobstructed and reliable, and prolong the service life of each hydraulic element. The rear smoke exhaust filter system ensures the air cleanliness of the roadway workplace.

除卻上述基本性能設(shè)計(jì)外，考慮到裝載作業(yè)的穩(wěn)定性問題，在穩(wěn)定性保障設(shè)置上有氣頂油助力制動(dòng)系統(tǒng)，制動(dòng)效果更靈敏，行駛更穩(wěn)定；采用負(fù)荷傳感、優(yōu)先轉(zhuǎn)向的分合流液壓系統(tǒng)、動(dòng)力換擋變速，整機(jī)操縱輕便靈活、動(dòng)作平穩(wěn)可靠；采用低壓寬基工程機(jī)械輪胎，后橋擺動(dòng)，具有良好的越野和通過性能，適應(yīng)崎嶇不平的路面上的穩(wěn)定行駛和作業(yè)。

In addition to the above basic performance design, considering the stability of loading operation, there is an air top oil assisted braking system in the stability guarantee setting, which makes the braking effect more sensitive and driving more stable; The split and merge hydraulic system with load sensing and priority steering and power shift speed change are adopted. The whole machine has light and flexible operation and stable and reliable action; The low-pressure wide base construction machinery tire is adopted, and the rear axle swings. It has good off-road and trafficability, and is suitable for stable driving and operation on rugged roads.
