Kev loj hlob ntawm scraper conveyor nyob rau hauv qhuav thiab kev tsim kho ntawm cov mine tau undergone peb theem. Thawj theem ntawm 30-40 xyoo, yog txawb scraper conveyor, nws tuaj yeem ncaj ncaj kab hauv lub ntsej muag, nrog rau kev ua ntej ntawm lub ntsej muag, yuav tsum tau manually dismantle, tsiv, sib sau. Scraper saw yog ib lub phaj, ntau rau ib qho saw, xws li V-hom, SGD-11 hom, SGD-20 hom, xws li lub hwj chim me lub zog scraper conveyor. Qhov thib ob theem yog thaum ntxov 40 los ntawm lub teb chaws Yelemees los tsim kom muaj cov txaj txeem txeem tsis taus, nws nrog lub shearer, hlau kev txhawb nqa kom muaj kev sib koom ua haujlwm. Qhov hom ntawm scraper conveyor hnoos kom haum rau hauv pem teb tsis sib haum convex sis tsis ncaj thiab kab rov tav txoj kab, lub tsiv tsis tas yuav tsum tau demolished, thiab cov nyiaj ntawm cov thauj thauj kuj nce, xws li cov qauv SGW-44 hom scraper Conveyor yog cov theem ntawm cov neeg sawv cev khoom. Rau hauv 60's vim qhov kev tshwm sim ntawm kev txhawb nqa hydraulic, thiaj li ua tau raws li cov kev xav tau ntawm cov mining, scraper conveyor txoj kev loj hlob mus rau theem peb, kev loj hlob ntawm high-power armored hnoos bending hnyav scraper conveyor, xws li sgd-630 / 75 hom, sgd-630/180 yam yog qhov khoom ntawm qib no.
Nrog rau kev tsim muaj peev xwm ntawm lub ntsej muag lub ntsej muag, qhov kev loj hlob tseem ceeb ntawm cov txee conveyor yog:
1. Loj ntim ntawm tsheb. Txawv tshaj tawm cov teb chaws tsuas tau tsim rau lub sijhawm thauj mus txog li 1500t (80 tus) 3500t (90) scraper conveyor.
2. Qhov kev thauj mus los ntev ntev. Yuav kom txo tau qhov poob ntawm cov pob zeb hauv qhov chaw ua haujlwm thiab nce qhov ntev ntawm kev ua hauj lwm nto, qhov ntev ntawm scraper conveyor tau mus txog ntau tshaj 335 meters.
3. Lub cav qev zog. Lub zog ntawm lub cev muaj peev xwm tsim tau rau ib qho kev tsav tsheb nce mus txog 525kW, ob lub tsheb tsav 500 / 250kw.
4, Lub neej ntev. Vim tias kev siv loj diam iav nplhaib, ua kom muaj zog ntawm txoj saw hlau, txuas ntxiv rau lub neej ntawm cov txee conveyor, tag nrho tshuab dhau tus nqi ntawm cov pob zeb tshaj 6 lab tons.
