Muab harvester: Yav tag los thiab tam sim

Nyob rau hauv ua liaj ua teb siv feem ntau ntau haiv neeg cov cav tov raws li lub dav thiab nqaim daim ntawv thov. Ntxiv mus, ib co hom yog ua hauj lwm thawm niaj thawm xyoo, thaum lwm tus neeg feem ntau ntawm cov sij hawm sawv kaw nyob rau hauv Hangars. Tab sis tsis muaj ib tug los yog lwm yam technology yuav tsis ua cov tswv teb. Piv txwv li, nyob rau hauv lub sau rau lub teb koj yuav saib tau lub muab harvester, uas nta yuav siv sij hawm hauv txoj hauj lwm ib lub teb haymakers. Thiab nws yog heev yooj yim ntxawm tshuab, uas yog ib tug kwj nruam thiab ua ob peb ua hauj lwm. Harvester txiav cereals, muab lawv mus rau lub ntaus mechanism thiab lub grain ntawm threshed pob ntseg. Ces nws cais nws los ntawm straw thiab lwm yam impurities thiab thauj nws mus rau lub hopper. Thiab vim hais tias nws muaj los ntawm lub sij hawm rau lub sij hawm los yog tsis tu ncua mechanically unloads lub grain mus rau lwm lub tsheb thauj mus los.

Nyob rau hauv hauv paus ntsiab lus, cov muab harvester xyoo xwb peb ntau yooj yim tshuab - Reaper, thresher thiab cov winnower. Thiab nws yog tau mus dai ntxiv Cheebtsam tias cia koj mus tshem tawm cov ntau yam cov qoob loo. Lub US yog ib lub tsev rau qhov no txuj ci tseem ceeb ntawm technology. Rov qab nyob rau hauv 1828, inventor S. Lane patented complex ua ke tshuab rau ntxawm lis cov qoob loo. Nws yuav tsum tau txiav cereal, thresh nws, thiab shuck pob kws. Tab sis nws yeej tsis tau ua. Thiab nyob rau hauv 1836, ob inventors los ntawm tib lub America tau mounted ib yam dab tsi zoo li ib tug muab harvester. Nws yog zoo li ib tug 4-wheeled wagon. Ib tug tsav kev sib hloov ntawm tej chav tsev thiab ntaus nruas iav nqa los ntawm lub rear qag.

Tab sis muab structurally tsa ib tug niaj hnub ua qauv, muaj kev tswj kom tau nyob rau hauv 1836 ob tug lwm inventors - J. Hascall thiab H. Moore. Thiab qhov no tshuab twb nyob rau hauv 1854 tshem tawm cov 600 acres ntawm pob kws. Ces maj mam muab harvester nce zoo tag nrho nrog rau txoj kev loj hlob ntawm technology. Thiab nyob rau hauv Russia thawj xws tshuab, manufactured los ntawm Holt, coj nyob rau hauv 1913. Nws yog ib tug ntoo qauv crawler. Nws muaj ib tug roj av cav, uas yog tseem powered mechanisms rau ntxawm thiab rau kev tshem. Tab sis thov no lub processor tsis muaj lub sij hawm, vim hais tias tsis ntev tsov rog pib.

Thiab thaum lub Soviet Union rau combines rov qab dua. Thaum xub thawj lawv tau mas ntawm lub tebchaws United States, nyob rau hauv thaum uas tig mus tsim kom muaj nws lawm. Thiab thawj muab harvester, uas corresponded rau tus nqi ntawm zog ntawm ntau cov neeg tshuav nyob rau hauv 1930 tawm ntawm lub qhov rooj ntawm lub Zaporozhye "Kommunar" nroj tsuag. By kawg ntawm xyoo ntawd, lub Hoobkas neeg ua hauj lwm twb tso 347 ntawm cov cav tov. Ib xyoo tom qab, lub Rostov tsob nroj "Rostselmash" pib los ua tus naas ej "Stalinists." Nyob rau hauv 1932, qhov kev tso tawm Combines tsim nyob rau hauv Saratov Refinery npe Shelbodaeva. Cov qauv nyob deb ntawm zoo meej, tab sis lawv pab villagers kom huv si. Thiab tom qab tsov rog nyob rau hauv lub Soviet Union nqa tawm loj kev tshawb fawb, uas tau nyob rau hauv tus qauv SC-5 thiab SC-6. Ces nyob rau hauv 1970 Taganrog cog pib ua Muab Harvester "pob ntseg" los yog SK-6-ll, thiab Rostselmash - "Field" SK-5.

Thiab cov cav tov rau ib ntev lub sij hawm furrowed teb ntawm lub Soviet Union, thiab ces ywj siab lub xeev. Thiab tam sim no lawv twb hloov los ntawm newer qauv xws li cov muab harvester "Polesie" GLC-812-16. Qhov no compact thiab manoeuvrable tshuab uas muaj ib tug bandwidth ntawm ntau tshaj 8 kg / s. Nws yog tau muab ib teev dhau 12 tons ntawm grain. Qhov no tsheb belongs rau lub hom ntxawm uas twb dav paub. Lawv muaj ib tug ntaus lub nruas, beater thiab straw yamntxwv. Thiab ib feem ntawm lub "Polesie" muab harvester muaj xws li grain-CSL 6-5 thiab propelled thresher qauv KPC-8-0100000.
