Kev sib cais ntawm cov khoom yog ib qho teeb meem tshwm sim hauv feem ntau cov cuab yeej cia.Raws li kev thov rau cov khoom lag luam zoo dua, qhov teeb meem ntawm kev sib cais ntawm cov khoom lag luam yuav mob hnyav dua.
Raws li peb txhua tus paub, telescopic radial stack conveyors yog cov kev daws teeb meem zoo tshaj plaws rau pawg sib cais.Lawv tuaj yeem tsim cov khoom muag hauv cov khaubncaws sab nraud povtseg, txhua txheej yog tsim los ntawm ntau cov ntaub ntawv.Txhawm rau tsim cov khoom muag hauv txoj kev no, lub conveyor yuav tsum khiav yuav luag tsis tu ncua.Thaum lub zog ntawm telescopic conveyors yuav tsum tau tswj manually, automation yog nyob deb ntawm txoj kev tswj tau zoo tshaj plaws.
Tsis siv neeg retractable conveyors tuaj yeem tsim los tsim cov khoom lag luam kev cai hauv ntau qhov ntau thiab tsawg, duab thiab teeb tsa.Qhov no tsis muaj kev txwv tsis pub hloov pauv tuaj yeem txhim kho kev ua haujlwm tag nrho thiab xa cov khoom zoo dua.
Cov neeg tsim khoom siv nyiaj ntau lab daus las txhua xyoo los tsim cov khoom sib sau ua ke rau ntau yam kev siv.Cov ntawv thov nrov tshaj plaws suav nrog cov ntaub ntawv hauv paus, asphalt thiab pob zeb.
Cov txheej txheem tsim cov khoom siv rau cov ntawv thov no nyuaj thiab kim.Tighter specifications thiab tolerances txhais tau hais tias qhov tseem ceeb ntawm cov khoom zoo tau dhau los ua qhov tseem ceeb.
Thaum kawg, cov khoom raug tshem tawm ntawm cov khoom ntim thiab thauj mus rau qhov chaw uas nws yuav muab tso rau hauv subgrade, asphalt lossis pob zeb.
Cov khoom siv uas yuav tsum tau siv rau stripping, blasting, crushing thiab tshuaj ntsuam yog kim heev.Txawm li cas los xij, cov cuab yeej siv siab heev tuaj yeem tsim cov khoom sib sau ua ke raws li kev qhia tshwj xeeb.Cov khoom lag luam yuav zoo li qhov tsis tseem ceeb ntawm kev tsim khoom sib xyaw, tab sis yog tias ua tsis raug, nws tuaj yeem ua rau cov khoom lag luam ua tau raws li cov lus qhia tsis ua raws li cov lus qhia.Qhov no txhais tau hais tias siv txoj kev khaws cia tsis raug tuaj yeem ua rau poob qee tus nqi ntawm kev tsim cov khoom zoo.
Txawm hais tias muab cov khoom tso rau hauv cov khoom muag tuaj yeem cuam tshuam nws qhov zoo, cov khoom muag yog ib feem tseem ceeb ntawm tag nrho cov txheej txheem tsim khoom.Nws yog ib txoj hauv kev khaws cia kom ntseeg tau tias muaj cov khoom siv.Tus nqi ntawm kev tsim khoom feem ntau txawv ntawm tus nqi ntawm cov khoom xav tau rau ib daim ntawv thov, thiab cov khoom muag pab tsim qhov sib txawv.
Cov khoom lag luam tseem muab cov neeg cog lus txaus qhov chaw cia kom teb tau zoo rau qhov kev xav tau ntawm kev lag luam.Vim yog cov txiaj ntsig uas khaws cia, nws yuav yog ib feem tseem ceeb ntawm tag nrho cov txheej txheem tsim khoom.Yog li ntawd, cov neeg tsim khoom yuav tsum txuas ntxiv txhim kho lawv cov cuab yeej cia kom txo tau qhov kev pheej hmoo cuam tshuam nrog kev cia khoom.
Lub ntsiab lus tseem ceeb ntawm kab lus no yog kev cais tawm.Segregation txhais tau tias yog "kev sib cais ntawm cov khoom raws li qhov loj me".Daim ntawv thov sib txawv ntawm cov khoom sib txawv yuav tsum muaj cov khoom siv tshwj xeeb thiab cov qib sib xws.Kev sib cais ua rau muaj kev sib txawv ntau dhau ntawm cov khoom ntau yam.
Kev sib cais tuaj yeem tshwm sim nyob txhua qhov chaw hauv cov txheej txheem tsim khoom sib sau ua ke tom qab cov khoom tau raug crushed, tshuaj ntsuam xyuas thiab sib xyaw kom zoo gradation.
Thawj qhov chaw uas muaj kev sib cais tuaj yeem tshwm sim hauv cov khoom muag (saib daim duab 1).Thaum cov khoom tau muab tso rau hauv cov khoom muag, nws thiaj li yuav rov siv dua thiab xa mus rau qhov chaw uas nws yuav siv.
Qhov thib ob qhov chaw uas kev sib cais tuaj yeem tshwm sim thaum lub sijhawm ua haujlwm thiab thauj.Ib zaug ntawm qhov chaw ntawm asphalt lossis pob zeb cog, cov khoom sib sau tau muab tso rau hauv hoppers thiab / los yog cov thawv ntim khoom los ntawm cov khoom siv thiab siv.
Kev sib cais kuj tshwm sim thaum sau thiab khoob silos thiab silos.Kev sib cais kuj tuaj yeem tshwm sim thaum lub sij hawm daim ntawv thov ntawm qhov kawg mix mus rau ib txoj kev los yog lwm qhov chaw tom qab cov aggregate tau tov rau hauv asphalt los yog qhob mix.
Homogeneous aggregate yog qhov tseem ceeb rau kev tsim cov khoom zoo asphalt lossis pob zeb.Kev hloov pauv hauv qhov kev sib tw ntawm cov detachable aggregate ua rau nws xyaum tsis yooj yim sua kom tau txais asphalt los yog pob zeb.
Cov khoom me me ntawm qhov hnyav tau muab qhov loj tag nrho ntawm thaj chaw ntau dua li cov khoom loj ntawm tib qhov hnyav.Qhov no tsim teeb meem thaum sib txuas cov aggregates rau hauv asphalt lossis pob zeb sib tov.Yog tias feem pua ​​​​ntawm kev nplua nyob rau hauv cov khoom sib sau siab dhau lawm, yuav muaj qhov tsis muaj mortar lossis bitumen thiab cov khoom sib xyaw yuav tuab heev.Yog hais tias feem pua ​​ntawm cov ntxhib hais nyob rau hauv lub aggregate yog siab dhau lawm, yuav muaj ib tug ntau tshaj ntawm mortar los yog bitumen, thiab cov sib xws ntawm cov sib tov yuav heev nyias.Txoj kev tsim los ntawm cov sib cais sib cais muaj cov qauv kev ua haujlwm tsis zoo thiab nws yuav muaj lub neej nyob qis dua li cov kev tsim los ntawm cov khoom sib cais.
Ntau yam ua rau muaj kev sib cais hauv cov khoom lag luam.Txij li feem ntau cov khoom muag tau tsim los ntawm kev siv cov khoom siv conveyor, nws yog ib qho tseem ceeb kom nkag siab txog qhov cuam tshuam ntawm cov khoom siv conveyor ntawm cov khoom siv.
Raws li txoj siv sia txav cov khoom hla ntawm txoj siv conveyor, txoj siv bounces me ntsis raws li nws dov hla lub idler pulley.Qhov no yog vim me ntsis slack nyob rau hauv txoj siv ntawm txhua idler pulley.Qhov kev txav no ua rau cov khoom me me nyob rau hauv qab ntawm qhov hla ntawm cov khoom.Overlapping cov coarse nplej khaws cia rau saum.
Sai li sai tau cov khoom mus txog lub log tawm ntawm txoj siv conveyor, nws twb yog ib feem ntawm cov khoom loj nyob rau sab saum toj thiab cov khoom me me nyob hauv qab.Thaum cov khoom pib txav mus raws qhov nkhaus ntawm lub log tawm, cov khoom sab sauv (sab nrauv) txav ntawm qhov nrawm dua li qhov qis (hauv) cov khoom.Qhov sib txawv ntawm qhov ceev no ua rau cov khoom loj dua txav mus deb ntawm lub conveyor ua ntej yuav poob rau hauv pawg, thaum cov khoom me me poob ntawm lub conveyor.
Tsis tas li ntawd, nws muaj feem ntau tias cov khoom me me yuav lo rau ntawm txoj siv conveyor thiab tsis raug tso tawm kom txog thaum lub conveyor siv txuas ntxiv mus rau ntawm lub log tawm.Qhov no ua rau cov khoom zoo dua rov qab mus rau pem hauv ntej ntawm pawg.
Thaum cov khoom ntog mus rau ib pawg, cov khoom loj dua muaj lub zog rau pem hauv ntej dua li cov khoom me me.Qhov no ua rau cov khoom ntxhib txuas ntxiv txav mus yooj yim dua li cov khoom zoo.Txhua yam khoom, loj lossis me, uas khiav mus rau sab ntawm pawg yog hu ua spill.
Kev nchuav yog ib qho ntawm cov laj thawj tseem ceeb ntawm cov khoom sib cais thiab yuav tsum tau zam thaum twg los tau.Raws li cov nchuav pib dov nqes ntawm txoj kab nqes ntawm qhov lwj, cov khoom loj dua yuav dov mus rau tag nrho qhov ntev ntawm txoj kab nqes, thaum cov khoom zoo dua yuav nyob ntawm ob sab ntawm qhov lwj.Yog li ntawd, raws li qhov nchuav nce mus rau sab ntawm pawg, tsawg dua thiab tsawg dua cov khoom zoo nyob hauv cov khoom siv.
Thaum cov khoom ncav cuag lub qab ntug lossis ntiv taw ntawm pawg, nws yog tsim los ntawm cov khoom loj dua.Kev nchuav ua rau muaj kev sib cais tseem ceeb, uas pom nyob rau hauv cov khoom seem.Cov ntiv taw sab nrauv ntawm pawg muaj cov khoom siv coarser, thaum lub puab thiab sab sauv pawg muaj cov khoom zoo dua.
Cov duab ntawm cov khoom kuj ua rau muaj kev phiv.Cov khoom uas du los yog puag ncig yog feem ntau yuav dov rau hauv txoj kab nqes ntawm pawg dua li cov khoom zoo, uas feem ntau yog square hauv cov duab.Tshaj qhov kev txwv kuj tuaj yeem ua rau cov khoom puas tsuaj.Thaum cov khoom dov ib sab ntawm pawg, lawv rub tawm rau ib leeg.Qhov hnav no yuav ua rau qee cov khoom tawg mus rau qhov me me.
Cua yog lwm qhov laj thawj rau kev sib cais.Tom qab cov khoom tawm ntawm txoj siv conveyor thiab pib poob rau hauv pawg, cua cuam tshuam rau txoj kev txav ntawm qhov sib txawv ntawm qhov sib txawv.Cua muaj kev cuam tshuam zoo rau cov khoom muag muag.Qhov no yog vim qhov piv ntawm thaj chaw ntawm thaj chaw rau qhov loj ntawm cov khoom me me yog ntau dua li cov khoom loj dua.
Qhov tshwm sim ntawm kev sib cais hauv cov khoom lag luam tuaj yeem sib txawv nyob ntawm seb hom khoom hauv lub tsev khaws khoom.Qhov tseem ceeb tshaj plaws nyob rau hauv kev sib raug zoo rau kev sib cais yog qhov kev hloov ntawm particle loj ntawm cov khoom.Cov khoom uas muaj qhov sib txawv me me ntau dua yuav muaj kev sib cais ntau dua thaum khaws cia.Ib txoj cai dav dav ntawm tus ntiv tes xoo yog tias yog tias qhov sib piv ntawm qhov loj tshaj plaws ntawm qhov loj tshaj plaws rau qhov me me tshaj qhov loj tshaj 2: 1, tej zaum yuav muaj teeb meem nrog pob cais.Ntawm qhov tod tes, yog tias qhov particle loj piv yog tsawg dua 2: 1, ntim cais yog tsawg.
Piv txwv li, subgrade cov ntaub ntawv uas muaj cov khoom mus txog 200 mesh tuaj yeem delaminate thaum khaws cia.Txawm li cas los xij, thaum khaws cov khoom xws li cov pob zeb ntxuav, cov rwb thaiv tsev yuav tsis tseem ceeb.Txij li feem ntau cov xuab zeb ntub dej, feem ntau nws tuaj yeem khaws cov xuab zeb yam tsis muaj teeb meem sib cais.Cov dej noo ua rau cov khoom sib txuas ua ke, tiv thaiv kev sib cais.
Thaum cov khoom khaws cia, kev sib cais qee zaum tsis tuaj yeem tiv thaiv.Sab nrauv ntawm pawg ua tiav yog feem ntau ntawm cov khoom ntxhib, thaum sab hauv ntawm pawg muaj ntau dua ntawm cov khoom zoo.Thaum noj cov khoom siv los ntawm qhov kawg ntawm cov pawg, nws yog ib qho tsim nyog yuav tsum tau nqa cov scoops los ntawm ntau qhov chaw los sib tov cov khoom.Yog tias koj nqa cov khoom siv los ntawm sab xub ntiag lossis sab nraub qaum ntawm pawg, koj yuav tau txais tag nrho cov khoom ntxhib lossis tag nrho cov khoom zoo.
Kuj tseem muaj sijhawm rau kev rwb thaiv tsev ntxiv thaum thauj cov tsheb thauj khoom.Nws yog ib qho tseem ceeb uas txoj kev siv tsis ua rau muaj kev ntws tawm.Load pem hauv ntej ntawm lub tsheb ua ntej, ces lub rear, thiab thaum kawg nyob rau hauv nruab nrab.Qhov no yuav txo qhov cuam tshuam ntawm overloading hauv lub tsheb.
Cov txheej txheem tom qab tuav cov khoom lag luam muaj txiaj ntsig zoo, tab sis lub hom phiaj yuav tsum yog los tiv thaiv lossis txo qis kev cais tawm thaum lub sijhawm tsim cov khoom muag.Txoj hauv kev zoo los tiv thaiv kev sib cais muaj xws li:
Thaum muab tso rau ntawm lub tsheb thauj khoom, nws yuav tsum tau muab tso rau hauv cov khoom sib cais kom huv si kom txo tau qhov nchuav.Cov khoom yuav tsum tau muab tso ua ke siv lub loader, nce mus rau tag nrho lub thoob qhov siab thiab pov tseg, uas yuav sib tov cov khoom.Yog tias lub tsheb thauj khoom yuav tsum txav thiab tawg cov khoom, tsis txhob sim ua cov pawg loj.
Kev tsim cov khoom muag hauv cov khaubncaws sab nraud povtseg tuaj yeem txo qis kev sib cais.Hom warehouse no tuaj yeem tsim nrog lub tsheb nrau av.Yog tias cov khoom raug xa mus rau lub vaj, lub bulldozer yuav tsum thawb cov khoom mus rau hauv txoj kab nqes.Yog hais tias pawg yog tsim nrog ib tug conveyor siv, lub bulldozer yuav tsum thawb cov khoom mus rau hauv ib tug kab rov tav txheej.Txawm li cas los xij, yuav tsum tau saib xyuas kom tsis txhob thawb cov khoom hla ntawm ntug ntawm pawg.Qhov no tuaj yeem ua rau cov dej ntws tawm, uas yog ib qho ntawm cov laj thawj tseem ceeb rau kev sib cais.
Stacking nrog bulldozers muaj ntau qhov tsis zoo.Ob qhov kev pheej hmoo tseem ceeb yog cov khoom lag luam degradation thiab kev sib kis.Cov khoom siv hnyav ua haujlwm tsis tu ncua ntawm cov khoom yuav compact thiab tsoo cov khoom.Thaum siv txoj kev no, manufacturers yuav tsum tau ceev faj kom tsis txhob over-degrade cov khoom nyob rau hauv ib qho kev sim los daws teeb meem kev sib cais.Kev ua haujlwm ntxiv thiab cov khoom siv uas xav tau feem ntau ua rau txoj kev no txwv tsis pub kim, thiab cov neeg tsim khoom yuav tsum tau mus rau kev sib cais thaum ua.
Radial stacking conveyors pab txo qhov cuam tshuam ntawm kev sib cais.Raws li cov khoom muag accumulates, lub conveyor txav radially mus rau sab laug thiab sab xis.Raws li lub conveyor txav radially, qhov kawg ntawm pawg, feem ntau ntawm cov khoom ntxhib, yuav raug them nrog cov khoom zoo.Cov ntiv tes pem hauv ntej thiab nraub qaum tseem yuav ntxhib, tab sis cov pawg yuav sib xyaw ntau dua li pawg ntawm cov cones.
Muaj kev sib raug zoo ntawm qhov siab thiab kev poob dawb ntawm cov khoom siv thiab qib ntawm kev sib cais uas tshwm sim.Raws li qhov siab nce thiab cov trajectory ntawm cov khoom ntog nthuav, muaj kev sib cais ntawm cov khoom zoo thiab ntxhib.Yog li qhov sib txawv qhov siab conveyors yog lwm txoj hauv kev los txo qis kev sib cais.Thaum pib, lub conveyor yuav tsum nyob rau hauv qhov chaw qis tshaj.Qhov kev ncua deb mus rau lub taub hau rub yuav tsum yog luv li sai tau.
Dawb-poob los ntawm txoj siv conveyor mus rau ib pawg yog lwm qhov laj thawj rau kev sib cais.Pob zeb ntaiv txo qis kev sib cais los ntawm kev tshem tawm cov khoom ntog dawb.Lub pob zeb staircase yog ib qho qauv uas tso cai rau cov khoom ntws los ntawm cov kauj ruam mus rau pawg.Nws siv tau tab sis muaj kev txwv tsis pub siv.
Kev sib cais los ntawm cua tuaj yeem txo qis los ntawm kev siv telescopic chutes.Telescopic chutes nyob rau hauv lub conveyor lub tso tawm sheaves, ncua los ntawm lub sheave mus rau pawg, tiv thaiv cua thiab txwv nws cov kev cuam tshuam.Yog tias tsim nyog, nws tuaj yeem txwv tsis pub poob ntawm cov khoom siv.
Raws li tau hais ua ntej, muaj qhov rwb thaiv tsev ntawm txoj siv conveyor ua ntej mus txog qhov chaw tawm.Tsis tas li ntawd, thaum cov khoom tawm ntawm txoj siv conveyor, kev sib cais ntxiv tshwm sim.Lub log paddle tuaj yeem ntsia tau ntawm qhov chaw tso tawm kom rov ua cov khoom siv no.Rotating log muaj tis los yog paddles uas traverse thiab sib tov txoj kev ntawm cov khoom.Qhov no yuav txo qis kev sib cais, tab sis cov khoom siv degradation yuav tsis raug.
Kev sib cais tuaj yeem ua rau cov nqi tseem ceeb.Cov khoom lag luam uas tsis ua raws li cov lus qhia tshwj xeeb yuav ua rau raug nplua lossis tsis lees paub tag nrho cov khoom muag.Yog tias cov khoom siv tsis raug xa mus rau qhov chaw ua haujlwm, kev nplua nyiaj tuaj yeem tshaj $ 0.75 ib tuj.Cov nqi zog thiab khoom siv rau kev kho cov kab mob tsis zoo yog feem ntau txwv tsis pub.Tus nqi ib teev ntawm kev tsim lub tsev rau khoom nrog lub tsheb bulldozer thiab tus neeg teb xov tooj yog siab dua tus nqi ntawm kev siv lub tshuab telescopic tsis siv neeg, thiab cov khoom siv yuav decompose los yog kis kab mob los tswj xyuas kom raug.Qhov no txo ​​cov nqi ntawm cov khoom.Tsis tas li ntawd, thaum cov cuab yeej siv xws li lub tsheb bulldozer siv rau cov haujlwm uas tsis yog kev tsim khoom, nws muaj peev xwm cuam tshuam nrog kev siv cov cuab yeej thaum nws tau nqis peev rau kev tsim khoom.
Lwm txoj hauv kev tuaj yeem raug coj los txo qhov cuam tshuam ntawm kev sib cais thaum tsim cov khoom muag hauv cov ntawv thov uas kev cais tawm tuaj yeem ua teeb meem.Qhov no suav nrog stacking nyob rau hauv cov khaubncaws sab nraud povtseg, qhov twg txhua txheej yog ua los ntawm ib tug series ntawm stacks.
Hauv pawg pawg, txhua pawg tau pom tias yog ib pawg me me.Qhov kev sib cais tseem tshwm sim ntawm txhua tus neeg heap vim tib qhov teebmeem uas tau tham ua ntej.Txawm li cas los xij, cov qauv kev sib cais feem ntau rov ua dua ntawm tag nrho cov ntu ntawm pawg.Cov pawg zoo li no tau hais tias muaj "kev daws teeb meem sib cais" ntau dua vim tias cov qauv gradient discrete rov ua dua ntau zaus ntawm qhov me me.
Thaum ua cov pawg nrog rau pem hauv ntej loader, tsis tas yuav muab cov ntaub ntawv sib xyaw, vim tias ib rab diav muaj ob peb pawg.Thaum cov txheej txheem rov qab los, cov txheej txheem ntawm tus kheej tau pom meej meej (saib daim duab 2).
Cov pawg tuaj yeem tsim tau siv ntau txoj hauv kev khaws cia.Ib txoj hauv kev yog siv tus choj thiab tso tawm qhov system, txawm hais tias qhov kev xaiv no tsuas yog tsim nyog rau kev siv nyob ruaj ruaj.Ib qho tsis zoo ntawm qhov chaw nres tsheb conveyor yog tias lawv qhov siab feem ntau yog tsau, uas tuaj yeem ua rau cua sib cais raws li tau piav qhia saum toj no.
Lwm txoj kev yog siv lub telescopic conveyor.Telescopic conveyors muab txoj hauv kev zoo tshaj plaws los tsim cov pawg thiab feem ntau nyiam tshaj qhov chaw nyob ruaj khov vim tias lawv tuaj yeem txav tau thaum xav tau, thiab ntau yam tau tsim los nqa ntawm txoj kev.
Telescopic conveyors muaj cov khoom siv conveyors (tus neeg saib xyuas conveyors) ntsia hauv cov khoom siv sab nraud ntawm tib qhov ntev.Lub taub hau conveyor tuaj yeem txav tau linearly raws qhov ntev ntawm cov khoom siv sab nraud kom hloov txoj haujlwm ntawm lub rub tawm rub tawm.Qhov siab ntawm lub log tawm thiab qhov radial txoj hauj lwm ntawm lub conveyor yog sib txawv.
Lub triaxial hloov ntawm lub log unloading yog qhov tseem ceeb los tsim cov txheej txheej uas kov yeej kev sib cais.Rope winch systems feem ntau yog siv los txuas ntxiv thiab thim rov qab pub conveyors.Lub radial txav ntawm lub conveyor tuaj yeem nqa tau los ntawm cov saw thiab sprocket system lossis los ntawm hydraulically tsav planetary tsav.Qhov siab ntawm lub conveyor feem ntau yog hloov los ntawm kev ncua lub telescopic undercarriage thooj voos kheej kheej.Tag nrho cov kev txav no yuav tsum tau tswj kom tau txais kev tsim ntau pawg.
Telescopic conveyors muaj cov txheej txheem los tsim cov kab ntau ntau.Kev txo qis qhov tob ntawm txhua txheej yuav pab txwv kev sib cais.Qhov no yuav tsum tau lub conveyor kom txav mus raws li cov khoom muag tsim.Qhov kev xav tau ntawm kev txav mus tas li ua rau nws tsim nyog rau kev siv lub tshuab telescopic conveyors.Muaj ntau ntau txoj kev automation sib txawv, qee qhov pheej yig dua tab sis muaj cov kev txwv tseem ceeb, thaum lwm tus yog cov programmable thiab muab kev yooj yim dua hauv kev tsim cov khoom muag.
Thaum lub conveyor pib sau cov khoom, nws txav radially thaum thauj cov khoom.Lub conveyor txav mus txog rau thaum muaj kev txwv kev hloov pauv ntawm lub conveyor ncej yog ua raws nws txoj kev radial.Tus txhais tau muab tso rau ntawm qhov ntev ntawm lub arc uas tus neeg teb xov tooj xav kom txoj siv conveyor txav mus.Lub sijhawm no, lub conveyor yuav txuas mus rau qhov kev ncua deb thiab pib txav mus rau lwm qhov.Cov txheej txheem no txuas ntxiv mus txog thaum lub stringer conveyor txuas mus rau nws qhov siab tshaj plaws txuas ntxiv thiab thawj txheej tiav.
Thaum qib thib ob tau tsim, lub taub pib thim rov qab los ntawm nws qhov siab tshaj plaws txuas ntxiv, txav radially thiab thim rov qab ntawm qhov txwv arcuate.Tsim cov khaubncaws sab nraud povtseg kom txog thaum lub qaij hloov mounted ntawm lub log txhawb nqa yog qhib los ntawm pawg.
Lub conveyor yuav nce mus rau qhov kev ncua deb thiab pib lub thib ob nqa.Txhua lub lifter tuaj yeem muaj ob peb txheej, nyob ntawm qhov ceev ntawm cov khoom.Qhov thib ob nqa tau zoo ib yam li thawj zaug, thiab lwm yam kom txog rau thaum tag nrho pawg tsim.Ib feem loj ntawm qhov tshwm sim heap yog de-isolated, tab sis muaj overflows ntawm ntug ntawm txhua heap.Qhov no yog vim cov siv conveyor tsis tuaj yeem hloov kho txoj haujlwm ntawm kev txwv hloov lossis cov khoom siv los ua kom lawv.Lub retract limit switch yuav tsum tau kho kom lub overrun tsis faus lub conveyor ncej.
