Tam sim no, txoj kev txiav ntawm stubble crushing thiab rov qab tshuab yog ua ke ntawm kev tawm tsam thiab txiav, thiab kev tawm tsam yog txoj hauv kev tseem ceeb [0.Cov riam siv feem ntau yog los ntawm 6 ~ Ua los ntawm 7mm 65Mn steel phaj, kev sib hloov ceev ntawm lub cutter ncej feem ntau yog 500r / min sab laug lossis sab xis lossis siab dua, qhov ceev qis dhau yuav cuam tshuam rau kev ua haujlwm zoo.
65Mn steel muaj siab toughness thiab zoo hnav tsis kam.tab sis txij li thaum lub cuab tam mus ntev kev sib cuag nrog av thiab xuab zeb thaum lub sij hawm ua hauj lwm, vim lub workload loj cuam tshuam thiab kev sib txhuam ntawm cov av ua rau hnyav hnyav hnyav, ua rau lub neej expectancy luv luv.Kev lag luam cutter ntawm cov nplej stubble rov qab tshuab, thaj chaw ua liaj ua teb tsuas yog kwv yees li 70hm", thiab cov cutters ntawm cov pob kws stubble rov qab tshuab, thaj chaw ua haujlwm tsuas yog li 40hm'. Yog tias cov hniav tsis hnav lub sijhawm.
Nws yuav nyuaj los xyuas kom meej qhov zoo ntawm chopping thiab nce lub zog siv yog tias nws hloov tau raws sijhawm.Tam sim no, saum toj-hauv av straw rov qab tshuab feem ntau siv high-speed rotating slingers.Cov riam (feem ntau yog oblique txiav L-shaped) txiav tawm ntawm cov ceg rov qab, thiab cov stalk tseem tsoo lub phaj npog, thiab raug txiav thiab tawg ntau zaus, cov stalks tawg yog nyob rau sab sauv ntawm rab riam tawm.Cov cav tov rau hauv av stubble crushing, xws li rotary stubble tshem tawm, Tshuab cuab yeej xws li vibration stubble tshem tawm, kab stubble tshem tawm, thiab compound stubble tshem tawm kuj tau tsim ib tug tom qab lwm.muab tso rau hauv thiab siv.Kev tshawb fawb ntawm cov riam tau dhau los ntawm cov tiller teb, chopping txoj kev loj hlob ntawm riam, ncaj stubble cutters rau nkhaus stubble cutters thiab nplawm riam, cov stubble txiav kev ua tau zoo ntawm cov riam yog tsis tu ncua, thiab kev tiv thaiv thiab lub zog noj yog obviously txo.Ntawm lawv, qhov ncaj-edged stubble cutter txais ib txoj kev txiav tsuas yog rau chopping thiab ntxiv los ntawm zawv zawg txiav.Txiav txoj kev, muaj zawv zawg txiav nyob rau hauv cov txheej txheem txiav, kom lub zawv zawg txiav lub kaum sab xis hloov conducive rau ruaj khov chopping.Vim qhov yooj yim tsim cov riam ncaj ncaj, los ntawm thiab siv dav.
2.1 Basic stubble hniav
Raws li cov duab, cov riam feem ntau suav nrog cov riam ncaj, L-shaped thiab hloov riam.Cov riam ntse, T-shaped riam, rauj claws thiab lwm yam.Ntawm lawv, hom L thiab nws hloov kho Cov riam pub yog tsuas yog siv rau pob kws, sorghum, paj rwb thiab lwm yam qoob loo.Lub chopping ntawm stalks yog tsuas yog raws li tshuab chopping, thiab txiav yog rau paving.Ntsej muag tsis tas yuav tsum tau.
