Cov ntaub ntawv uas lub tshuab khawb av tau khawb yog cov av, thee, xuab zeb, av thiab pob zeb tom qab ua ntej loosening. Los ntawm kev tsim cov tshuab siv hauv xyoo tas los no, kev tsim cov tshuab khawb av tau nrawm heev, thiab cov tshuab khawb av tau dhau los ua ib qho ntawm cov tshuab siv tseem ceeb tshaj plaws hauv kev tsim kho vaj tse.
Thawj tiam ntawm cov excavators: qhov tshwm sim ntawm cov cav hluav taws xob thiab cov cav combustion sab hauv ua rau cov excavators muaj cov khoom siv hluav taws xob siab heev thiab tsim nyog, yog li ntau yam khoom excavator tau yug los ib qho tom qab ib qho. Xyoo 1899, thawj lub tshuab hluav taws xob excavator tau tshwm sim. Tom qab Tsov Rog Thoob Ntiaj Teb Zaum Ib, cov cav diesel kuj tau siv rau hauv cov excavators. Lub cav diesel (lossis lub cev muaj zog hluav taws xob) tsav tsheb excavator yog thawj tiam ntawm cov excavators.
Lub cim thib ob ntawm cov excavators: Nrog rau kev siv ntau yam thev naus laus zis hydraulic, lub excavator muaj cov khoom siv kis tau zoo dua thiab siv tau. Kev kis tau hydraulic es tsis yog kev kis tau tshuab yog qhov kev dhia loj hauv thev naus laus zis excavator. Lub tshuab hydraulic excavator thawj zaug hauv lub teb chaws Yelemees tau yug los rau xyoo 1950. Kev kis tau tshuab hydraulic yog tiam thib ob ntawm cov excavators.
Lub tiam thib peb ntawm cov excavators: Kev siv dav dav ntawm cov thev naus laus zis hluav taws xob, tshwj xeeb tshaj yog cov thev naus laus zis computer, ua rau lub excavator muaj lub kaw lus tswj hwm tsis siv neeg, thiab tseem ua rau lub excavator txhim kho mus rau hauv kev ua haujlwm siab, automation thiab kev txawj ntse. Kev tawg ntawm mechatronics tshwm sim nyob ib puag ncig xyoo 1965, thiab kev siv cov thev naus laus zis mechatronics ntawm cov hydraulic excavators loj-tsim yog nyob ib puag ncig xyoo 1985, thaum lub hom phiaj tseem ceeb yog txuag hluav taws xob. Excavator electronics yog lub cim ntawm tiam thib peb ntawm cov excavators.
Cov khoom siv excavator feem ntau yog tsim los ntawm ob ntu: cov khoom siv kho tshuab thiab cov khoom siv hluav taws xob.
1. Cov khoom siv kho tshuab tsuas yog cov khoom siv kho tshuab los muab kev txhawb nqa fais fab, feem ntau suav nrog cov twj hydraulic, cov thoob tuav, cov booms, cov kev, cov cav, thiab lwm yam.
2. Cov khoom siv hluav taws xob yog qhov tsav tsheb tswj ntawm lub excavator, uas yog siv los tsav cov khoom siv kho tshuab kom ua haujlwm tsim nyog, feem ntau suav nrog lub khoos phis tawj, hydraulic flow controller, lub kaum sab xis sensor, diesel meter, fuse, ignition switch, roj suction twj, thiab lwm yam.
Cov khoom siv kho tshuab thiab qhov chaw tswj hwm tsav tsheb sib pab ua ke. Qhov chaw tswj hwm hluav taws xob siv los tsav thiab sib koom tes ua haujlwm zoo ntawm txhua qhov chaw kho tshuab. Qhov xwm txheej ntawm qhov chaw kho tshuab raug pub rov qab rau qhov chaw tswj hwm hluav taws xob los ntawm cov khoom siv hluav taws xob, yog li kom sib koom tes ua haujlwm ntawm lub tshuab khawb av kom ua tiav nws qhov kev ua haujlwm zoo tshaj plaws.
Lub cuab yeej ua haujlwm yog qhov tseem ceeb ntawm lub tshuab hydraulic excavator. Nws feem ntau yog siv los khawb cov av hauv qab qhov chaw nres, tab sis nws kuj tseem tuaj yeem khawb cov av hauv qab qhov siab tshaj plaws. Ntxiv nrog rau kev khawb, ditching thiab loading, nws kuj tseem tuaj yeem ua haujlwm yooj yim ntawm qhov chaw. Kev ua haujlwm khawb av yog qhov tsim nyog rau kev khawb cov av ntawm qib Ⅰ ~ Ⅳ, thiab yuav tsum muaj hydraulic rauj lossis blasting txoj kev rau qib Ⅴ saum toj no.
Lub cuab yeej ua haujlwm backhoe yog tsim los ntawm boom, stick, thoob, rocker, txuas pas nrig, thiab cov kav dej hydraulic ntawm lub cuab yeej ua haujlwm suav nrog lub tog raj kheej boom, lub tog raj kheej stick thiab lub tog raj kheej thoob.
