Chomera Chopangidwa ndi Chitsulo cha 65Mn, Zida Zogwiritsa Ntchito Dothi ndi Kutentha kwa Alimi a Zaulimi

Kufotokozera Kwachidule:

Monga gawo lofunikira kwambiri komanso losavuta kuwononga makina olima, pulawo limagwira ntchito yofunika kwambiri yodula, kuswa, ndi kutembenuza nthaka. Ubwino wake umakhudza mwachindunji momwe ulimi umagwirira ntchito, kugwiritsa ntchito mafuta, komanso malo okulira mbewu. Chogulitsachi chapangidwira makamaka malo olima minda youma ndi mpunga ndipo chimagwirizana ndi ma rotary tillers osiyanasiyana, ma moldboard plows, ndi subsoilers onse m'dziko muno komanso padziko lonse lapansi.

Tsamba la pulawo, lomwe ndi gawo lothandizira pa makina a ulimi, limapangidwa ndi chitsulo champhamvu kwambiri, chosatha kutha ndipo limakonzedwa ndi kutentha kuti likhale lolimba komanso lolimba. Mphepete mwake yakuthwa imachepetsa kukana kulowa m'nthaka, ndikudula bwino nthaka ndi mizu ya mbewu. Tsamba losalala limathandiza kuchotsa nthaka mosavuta ndikuletsa kumatirira kwa nthaka. Loyenera kulima m'malo osiyanasiyana a nthaka, limachepetsa kwambiri kugwiritsa ntchito mphamvu ndipo ndi gawo labwino kwambiri lolowa m'malo mwa mathirakitala ndi makina olima.

Njira yopangira imagwiritsa ntchito ukadaulo wolondola wopangira, kuonetsetsa kuti kupirira kwa kupindika kwa pamwamba pa fosholo ndi malo oikira mabowo kumayendetsedwa mkati mwa ± 0.5mm, zomwe zimapangitsa kuti chigwirizanidwe bwino ndi mzati wa pulawo ndikuletsa kugwedezeka kapena kupsinjika panthawi yogwira ntchito. Mphepete mwachitsulocho imaphwanyidwa ndi kukonzedwanso, kuchepetsa kukana kulowa kwa nthaka ndi 15%-20% ndikusunga bwino kugwiritsa ntchito mafuta a thirakitala.

Tsamba la pulawo likupezeka m'zinthu ziwiri: chitsulo cha masika cha 65Mn ndi chitsulo cha boron chosatha kuuma cha manganese. Tsamba la 65Mn, pambuyo pa kutentha konse, limapeza kuuma kwa tsamba la 48-52 HRC, kuphatikiza mphamvu yayikulu ndi kulimba kwabwino, zomwe zimapangitsa kuti likhale loyenera kulima loam wamba ndi loam wamchenga. Chitsulo cha boron cha manganese chapamwamba, pambuyo pa kuzimitsa kwa isothermal, chimadziwonetsa chokha pamwamba pake chikakhudzidwa ndi zinthu zomwe zimawonongeka, ndikuwonjezera nthawi yake yogwiritsidwa ntchito ndi zoposa 40% poyerekeza ndi masamba wamba a pulawo, zomwe zimapangitsa kuti likhale loyenera kwambiri nthaka yolimba yokhala ndi miyala yambiri kapena kukanikiza kwambiri.

Tsamba lolunjika: Pogwiritsa ntchito kapangidwe kake kozungulira kozungulira, nthaka imayenda bwino motsatira tsamba, zomwe zimapangitsa kuti nthaka ichotsedwe bwino komanso kuti matope azigwirana bwino, zomwe zimapangitsa kuti ikhale yoyenera kwambiri m'malo okhala ndi dothi.

Chigawo cholimba chosatha kutha: Chigawo cha aloyi cholimba cha 2-3mm chotha kutha chimamangiriridwa ku nsonga ya tsamba ndi gawo lakutsogolo, zomwe zimapangitsa kuti chiwonjezeke kwambiri.

Mawonekedwe Okhazikika: Mabowo oikira akugwirizana ndi miyezo ya ISO ndi miyezo yayikulu yamakampani amakampani a ulimi, yogwirizana ndi mapulawo ochokera ku makampani monga Lovol, Dongfanghong, ndi John Deere.
