Mabala a pulawo abwino kwambiri osawonongeka, zida zamakina a ulimi, masamba a rotary tiller.
Monga chinthu chofunikira komanso chosavuta kugwiritsa ntchito mu makina a ulimi chomwe chimakhudza nthaka mwachindunji ndikuchita ntchito zodula ndi kutembenuza, magwiridwe antchito a tsamba la pulawo amakhudza mwachindunji ubwino wa ulimi, magwiridwe antchito, komanso kugwiritsa ntchito mafuta. Tsamba la pulawo ili limapangidwa ndi chitsulo chapamwamba cha 65Mn spring steel kapena 30MnB high-manganese boron steel (ngati mukufuna), chopangidwa kudzera mu njira zotenthetsera zotentha komanso njira zambiri zotenthetsera, chokhala ndi mphamvu zambiri, kuuma kwambiri, komanso kulimba kwambiri, ndipo ndi choyenera mitundu yosiyanasiyana ya mapulawo osinthika, mapulawo a moldboard, ndi mapulawo otsetsereka.
1, Kukana kwabwino kwambiri kovala:
Tsamba la pulawo limaphwanyidwa pamalopo, zomwe zimapangitsa kuti pamwamba pake pakhale kuuma kwa 48–52 HRC, pomwe limasunga kulimba bwino pakati. Izi zimawonjezera kwambiri kukana kwake kuwonongeka m'mikhalidwe yovuta monga dothi lamchenga ndi nthaka ya miyala, zomwe zimawonjezera nthawi yake yogwirira ntchito ndi 30%–50% poyerekeza ndi mafosholo wamba achitsulo.
2, kapangidwe ka tsamba lodzilimbitsa lokha:
Kapangidwe kake kamakono kamatsimikizira kuthwa kosalekeza panthawi yogwira ntchito, kuchepetsa kukana kukoka ndi kugwiritsa ntchito mafuta pamene nthaka ikuphwanyika bwino komanso bwino.
Zipangizo: 65Mn / 30MnB (kapena monga momwe kasitomala wanenera)
Kulimba: 48–52 HRC ya m'mphepete mwachitsulo, 40–45 HRC ya nkhope ya fosholo
Njira: Kupangira ufa + Kutenthetsa ndi kutentha kotsala + Kupera kolondola
Ma Model Ogwirizana: Mapulawo osiyanasiyana opindika a hydraulic okhala ndi magawo awiri mpaka asanu ndi limodzi ndi mapulawo otsatizana
