Lub hauv paus ntawm kev yug me nyuam ntawm lub tshuab yog qhov yuav tsum tau ywg dej rau cov teb ntawm cov neeg ua liaj ua teb thaum ub ntawm Egypt, Mesopotamia, Tuam Tshoj, Is Nrias teb. Nws paub tias cov neeg ua liaj ua teb hauv cov tebchaws no tau raug yuam kom ua dej rau lawv cov qoob loo ntev ntev. Thiab tom qab ntawd ib txoj hauv kev tau pom nrog kev pab los ntawm cov khoom siv thaum ntxov los npaj kev thauj mus los ntawm dej. Lawv raug hu sib txawv nyob rau hauv txawv teb chaws, tab sis lub hauv paus ntsiab lus yog tib yam. Me ntsis tom qab, nrog kev tsim lub log, tib neeg tau kawm siv lub zog ntawm dej rau kev ua haujlwm zoo li no.

Nyob rau hauv Ancient tim Nkij teb chaws thiab Roman faj tim teb chaws, mills, kav dej, thiab lwm yam mechanisms tau teem nyob rau hauv cov kev taw qhia nrog kev pab los ntawm cov qhev, thiab tom qab ntawd nrog kev pab los ntawm cov tsiaj.

theem kev cog qoob loo

Tab sis txoj siv sia siv tau zoo, paub txog peb thiab npaj rau kev siv, tsuas yog tshwm sim hauv xyoo pua 18th. Thaum xub thawj, ib lub rooj tsavxwm tau ua lub hauv paus rau lawv, nrog rau cov ribbon ntawm tawv lossis canvas txav. Nyob rau hauv 1908, Heiml Goddard patented cov menyuam puag rau conveyors. Tab sis tus "niam txiv" tiag tiag ntawm txoj siv conveyor yog Henry Ford,leej twg pom tias cov neeg ua haujlwm tau nkim sijhawm ntau dhau los ua cov khoom siv ua haujlwm thiab txhim kho cov khoom siv conveyor uas tau hloov cov khoom ntawm ib lub khw mus rau lwm qhov. Qhov no ua rau muaj kev nce hauv kev ua haujlwm ntawm kev ua haujlwm, txo tus nqi ntawm kev tsim khoom thiab dhau los ua qhov pib ntawm kev tsim cov khoom siv conveyors.

Lub sijhawm dhau mus, cov txheej txheem rau kev txav khoom tau dhau los ua qhov zoo tshaj plaws. Belt conveyors tau txais ib puag ncig tshiab ntawm kev txhim kho nrog kev tsim kho kev lag luam ntawm ntau qhov tso nyiaj (thaum lub sij hawm rho tawm ntawm kub, thee, ores).

Types and scope

Hnub no, ntau yam ntawm cov khoom siv tau zoo heev. Nrog kev pab los ntawm lawv peb tau txais cov khoom ntawm lub tshav dav hlau, khob cij thiab confectionery factories ua hauj lwm, cov ntawv xov xwm luam tawm, tsheb yog sib sau ua ke, thee yog lifted los ntawm mines thiab pob zeb yog tsiv mus nyob deb deb ntawm quarries.

Kev siv cov khoom siv txuag lub sijhawm, tso cai rau koj los txhim kho cov txheej txheem tsim khoom thiab tshem tawm cov kev siv zog hnyav.

Nws cov cuab yeej, piv nrog rau lwm lub tshuab nqa, yog qhov yooj yim heev, nws yooj yim kho thiab ua haujlwm. Cov khoom tseem ceeb ntawm cov conveyor yog:

• txhawb nqa (nyob ruaj khov lossis hloov kho rau kev txav mus los);
• siv conveyor tsav, uas muaj lub tshuab hluav taws xob, lub iav iav (cylindrical, worm, saw lossis siv tsav, lossis siv iav) thiab lub nruas tsav;
• txhawb qhov chaw (cov yob lossis cov ntawv hlau);
• bearing body - conveyorribbon;
• nro mechanism (nruas thiab ntsia hlau).

Txhawm rau txav ntau yam ntaub ntawv, ntau hom kev siv cov khoom siv tau tsim:

• tape;
• lamellar;
• inertial;
• vibrating;
• roller;
• scraper;
• ncua kev thauj khoom thauj;
• pushing;
• trolley;
• thoob thiab txaj;
• screw.

Qee tus ntawm lawv muaj lub hom phiaj tshwj xeeb, piv txwv li, rau kev thauj cov neeg caij tsheb (cov nce toj). Kev taw qhia ntawm kev txav ntawm cov khoom tuaj yeem yog ib qho - kab rov tav, inclined, ntsug.

Tseeb tiag, txoj siv sia conveyor muaj cov xwm txheej ntawm cov txheej txheem nrov tshaj plaws rau kev txav yuav luag txhua yam khoom siv. Niaj hnub nimno electronics thiab automation nce nws lub peev xwm ntau zaus.
