摘 要
刮板輸送機(jī)是一種撓性牽引的連續(xù)輸送機(jī)械，是為采煤工作面和采區(qū)巷道運(yùn)煤布置的機(jī)械。它的牽引機(jī)構(gòu)是刮板鏈，承載裝置是中部槽，刮板鏈安裝在中部槽的槽面。中部槽沿運(yùn)輸路線全線鋪設(shè)，刮板鏈繞經(jīng)機(jī)頭、機(jī)尾的鏈輪接成封閉形置于中部槽中，與滾筒采煤機(jī)和輸送機(jī)推移裝置配套，實(shí)現(xiàn)落煤、裝煤、運(yùn)煤及推移輸送機(jī)械化。沿輸送機(jī)全長(zhǎng)都可向溜槽中裝煤，裝入中部槽中的煤被刮板鏈拖拉，在中部槽內(nèi)滑行到卸載端卸下。
一般的刮板輸送機(jī)能在25°以下的條件使用。刮板輸送機(jī)在使用中要受拉、壓、彎曲、沖擊摩擦和腐蝕等多種作用，因此，必須有足夠的強(qiáng)度、剛度、耐磨和耐腐蝕性。由于它的運(yùn)輸方式是物料和刮板鏈都在槽內(nèi)滑行，因此運(yùn)行阻力和磨損都很大。但是，在采煤工作面運(yùn)煤，目前還沒(méi)有更好的機(jī)械可代替，只能從結(jié)構(gòu)上、強(qiáng)度上和制造工藝上不斷研究，使它更加完善、耐用。
刮板輸送機(jī)是與大型綜采工作面設(shè)備配套使用的液壓支架、采煤機(jī)，完成把工作面采煤機(jī)采下的煤輸送、轉(zhuǎn)運(yùn)到后續(xù)運(yùn)輸設(shè)備上的任務(wù)，并提供相應(yīng)的連接手段。設(shè)計(jì)要求與ZY2300轉(zhuǎn)載機(jī)自移機(jī)尾配套，以實(shí)現(xiàn)在2.3米范圍內(nèi)整體移動(dòng)而不必拆移輸送機(jī)。與ZY2300轉(zhuǎn)載機(jī)自移機(jī)尾配合可更方便地調(diào)節(jié)皮帶機(jī)，增強(qiáng)了輸送機(jī)與轉(zhuǎn)載機(jī)配合的協(xié)調(diào)性。本刮板輸送機(jī)與MG300/700-WD采煤機(jī)配套使用，運(yùn)量可達(dá)1000t/h，技術(shù)先進(jìn)，工作可靠，是大型綜采配套設(shè)備的優(yōu)秀機(jī)型。

Scraper conveyor
Scraper conveyor is a reprint of fully coal face ancillary equipment in the transport system an important part of the roadway in the face of the accepted face scraper conveyor unloading of coal flow, not halt the transfer to the retractable belt Conveyor boost. Bridge reversed loader with the face-scraper conveyor machine synchronous over his head, face Shearer guarantee for coal mining, and fully mechanized coal face of high yield and high efficiency operations.
Scraper conveyor is a reprint of a special structure of the scraper conveyor, powertrain and drive and scraper conveyor similar to a ramp of its fuselage and a section of the arch bridge structure and belt conveyors in the tail Paragraph above lap. In the back-alley in the coal face when the machine goes to reprint its arch bridge and all of the aircraft ended the lap belt conveyor stack of position limits, a retractable belt conveyor shortened ride Next length of the belt conveyor for the development of the shift to home-unloading nose reproduced below, can be reproduced with the face of the advance goes forward.
Reproduced large-scale machine is fully coal face with the equipment supporting the use of the Gate transmission, reproduced equipment, to complete the face conveyor sent to the coal transportation, transit facilities to follow up on the conveyor belt of tasks and to provide the appropriate means of connection. ZY2300 belt with the design requirements for supporting the tail since the shift to achieve in the 2.3 metres of the overall mobile rather than demolished shift belt machine. ZY2300 belt and the tail of the shift can be more easily cope with belt-regulation, enhance the belt-and-reproduced with the coordination. This reprint of MG300/700-WD and supporting the use of conveyor, capacity up to 1,000 tons / hour, technologically advanced, reliable, large-scale comprehensive mining equipment supporting the excellent models.
Key words：scraper conveyor； reducer； machine head； aircraft tail； hydraulic coupler。
