Common excavators

Common excavators muab faib ua ob hom: internal combustion engine-driven excavators thiab hluav taws xob-tsav excavators.Ntawm lawv, hluav taws xob excavators tsuas yog siv nyob rau hauv toj siab hypoxia, underground mines thiab lwm qhov chaw flammable thiab tawg.
Raws li qhov ntau thiab tsawg, excavators tuaj yeem muab faib ua cov excavators loj, nruab nrab excavators thiab me excavators.
Raws li kev taug kev sib txawv, excavators tuaj yeem muab faib ua crawler excavators thiab log excavators.
Raws li cov qauv sib txawv, excavators tuaj yeem muab faib ua hydraulic excavators thiab mechanical excavators.Cov tshuab excavators feem ntau yog siv hauv qee qhov mines loj.
Raws li lub hom phiaj, excavators tuaj yeem muab faib ua dav dav excavators, mining excavators, marine excavators, tshwj xeeb excavators, thiab lwm yam.
Raws li lub thoob, excavators yuav muab faib ua pem hauv ntej duav, backhoe, dragline thiab lob duav.Pem hauv ntej shovels feem ntau yog siv los khawb cov ntaub ntawv saum npoo av, thiab backhoes feem ntau yog siv los khawb cov ntaub ntawv hauv qab no.
1. Backhoe Hom backhoe yog feem ntau peb tau pom, thim rov qab, yuam txiav cov av.Nws tuaj yeem siv rau kev khawb hauv qab qhov chaw ua haujlwm kaw.Cov txheej txheem kev ua haujlwm yooj yim yog: ditch kawg excavation, ditch side excavation, ncaj kab excavation, nkhaus excavation, tswj ib tug tej lub kaum sab xis excavation, ultra-dav trench excavation thiab trench nqes hav excavation, thiab lwm yam.
2. Pem hauv ntej duav excavator
Kev ua haujlwm ntawm shovel daim ntawv ntawm lub hauv ntej duav excavator.Nws tus yam ntxwv yog "rau pem hauv ntej thiab nce siab, yuam cov av txiav".Lub shovel pem hauv ntej muaj lub zog khawb loj thiab tuaj yeem khawb cov av saum qhov chaw nres tsheb.Nws yog tsim rau excavating qhuav foundation pits nrog qhov siab ntawm ntau tshaj 2m, tab sis nce thiab nqis ramps yuav tsum tau teem.Lub thoob ntawm lub duav pem hauv ntej yog loj dua li ntawm lub backhoe excavator ntawm tib qhov sib npaug, thiab nws tuaj yeem khawb cov khoom nrog cov dej tsis ntau tshaj 27%.
Rau peb hom av, thiab koom tes nrog cov tsheb thauj khoom pov tseg kom tiav tag nrho cov kev khawb thiab kev thauj mus los, thiab tseem tuaj yeem khawb qhov loj qhuav hauv paus pits thiab mounds.Txoj kev excavation ntawm lub duav pem hauv ntej yog nyob ntawm qhov sib txawv ntawm txoj kev excavation thiab qhov txheeb ze ntawm lub tsheb thauj khoom.Muaj ob txoj hauv kev khawb thiab tshem tawm cov av: pem hauv ntej khawb, sab unloading;pem hauv ntej khawb, thim rov qab.Txhawm rau tshem tawm cov av.
3. Dragline excavator
Draglines tseem hu ua draglines.Cov yam ntxwv ntawm nws excavation yog: "rov qab thiab downward, txiav cov av nyob rau hauv nws tus kheej hnyav".Nws yog tsim rau excavation ntawm Class I thiab II xau hauv qab qhov chaw nres.Thaum ua hauj lwm, lub thoob yog muab pov tseg los ntawm inertial quab yuam, thiab qhov khawb qhov deb kuj loj, thiab khawb lub vojvoog thiab khawb qhov tob yog loj, tab sis nws tsis yog raws li saj zawg zog thiab yog raws li lub backhoe.Tshwj xeeb tshaj yog tsim rau excavating loj thiab tob foundation pits los yog underwater excavation.
4. Nqa thiab duav excavator
Grab excavator tseem hu ua grab excavator.Cov yam ntxwv ntawm nws excavation yog: "ncaj nce thiab nqis, txiav cov av nyob rau hauv nws tus kheej hnyav".Nws yog tsim rau excavation ntawm Class I thiab II xau hauv qab qhov chaw nres tsheb, thiab feem ntau yog siv rau kev khawb ntawm lub hauv paus pits thiab caissons hauv cov av mos.Nws yog tshwj xeeb tshaj yog haum rau kev khawb tob thiab nqaim lub hauv paus pits, dredging qub raws, excavating silt nyob rau hauv dej, thiab lwm yam., los yog rau loading xoob cov ntaub ntawv xws li gravel thiab slag.Muaj ob hom excavation: trench side excavation thiab positioning excavation.Yog tias qhov rub tau ua rau hauv daim phiaj, nws tseem tuaj yeem siv rau kev thauj khoom ore blocks, ntoo chips, ntoo, thiab lwm yam.
Tag nrho hydraulic azimuth excavator
Feem ntau ntawm cov niaj hnub excavators yog tag nrho hydraulic azimuth excavators.Hydraulic excavators yog tsim los ntawm lub cav, hydraulic system, ua hauj lwm ntaus ntawv, mus txawv tebchaws ntaus ntawv thiab hluav taws xob tswj.Lub tshuab hydraulic muaj cov twj tso kua mis hydraulic, tswj valve, hydraulic lub tog raj kheej, hydraulic lub cev muaj zog, cov kav dej, roj tank, thiab lwm yam. Lub tshuab hluav taws xob muaj xws li kev tswj xyuas vaj huam sib luag, lub cav tswj qhov system, twj tso kua mis tswj system, ntau yam sensors, solenoid li qub, thiab lwm yam.
Hydraulic excavators feem ntau yog tsim los ntawm peb qhov chaw: cov cuab yeej ua haujlwm, lub cev sab sauv thiab lub cev qis.Raws li nws cov qauv thiab kev siv, nws tuaj yeem muab faib ua: hom crawler, hom log tsheb, hom taug kev, tag nrho hydraulic, semi-hydraulic, tag nrho kev sib hloov, tsis muaj kev sib hloov, hom dav dav, hom tshwj xeeb, hom articulated, telescopic boom hom thiab lwm hom.
Cov cuab yeej ua haujlwm yog cov cuab yeej uas ncaj qha ua tiav cov haujlwm excavation.Nws yog hinged los ntawm peb qhov chaw: boom, stick thiab thoob.Txhawm rau ua kom tau raws li qhov xav tau ntawm ntau yam kev tsim kho, hydraulic excavators tuaj yeem nruab nrog ntau yam khoom siv ua haujlwm, xws li khawb, nqa, thauj khoom, qib, clamps, bulldozing, cuam tshuam rauj, teb drilling thiab lwm yam khoom siv ua haujlwm.
Lub slewing thiab mus ncig ua si yog lub cev ntawm hydraulic excavator, thiab sab sauv ntawm lub turntable yog muab nrog ib lub hwj chim ntaus ntawv thiab ib tug kis tau tus mob system.Lub cav yog lub zog ntawm hydraulic excavator, feem ntau siv cov roj diesel nyob rau hauv qhov chaw yooj yim, thiab tseem tuaj yeem siv lub tshuab hluav taws xob hloov.
Lub hydraulic kis tau tus mob kis tau lub zog ntawm lub cav mus rau lub hydraulic lub cev muaj zog, hydraulic lub tog raj kheej thiab lwm yam actuators los ntawm lub hydraulic twj tso kua mis, thiab thawb qhov kev txiav txim ntawm cov cuab yeej ua hauj lwm kom tiav ntau yam hauj lwm.
