Zipangizo zamakina a ulimi: Mapulawo, mbale zolumikizira pulawo zosatha

Kufotokozera Kwachidule:

Ichi ndi chinthu chachikulu chomwe chimagwiritsidwa ntchito ndi mapulawu a moldboard, okhala ndi mawonekedwe ovuta opindika. Chopangidwa ndi chitsulo champhamvu kwambiri, chosatha kutha komanso chotenthetsera kutentha, chimakhala ndi kuuma kwakukulu komanso kulimba kwabwino kwambiri. Malo ake opindika osalala amakwaniritsa bwino kutembenuza ndi kuswa mabulondo a nthaka kumbali, kuchepetsa kwambiri kukana kulima. Chimawonetsa mphamvu zabwino zochotsera nthaka komanso nthawi yayitali yogwiritsidwa ntchito, zomwe zimapangitsa kuti chikhale chofunikira kwambiri pakukweza ubwino wa chivundikiro cha nthaka cholimidwa komanso kugwira ntchito bwino.

Chomera cholima, monga gawo lalikulu la pulawo la bolodi, chimagwira ntchito limodzi ndi pulawo ndipo chimatsimikizira mwachindunji momwe ulimi umagwirira ntchito komanso ubwino wake. Chomerachi chapangidwira makamaka ulimi wamakono ndipo ndi choyenera kugwiritsidwa ntchito pamodzi m'minda youma, minda ya mpunga, ndi dothi ladothi. Tadzipereka kupatsa ogwiritsa ntchito pulawo zapamwamba zomwe sizimalimbana ndi nthaka, zimachotsa nthaka mwachangu, komanso sizimawonongeka nthawi yayitali kudzera mu kukonza zinthu zapamwamba komanso kapangidwe kake ka aerodynamic, zomwe zimathandiza kuti ulimi ukhale wothandiza komanso wosunga mphamvu.

Chogulitsachi chimagwiritsa ntchito chitsulo champhamvu cha boron kapena chitsulo cha manganese-boron cholimba ngati maziko ndipo chimadutsa mu njira yonse yochizira kutentha kuti chitsimikizire kuuma bwino komanso kulimba kuyambira pamwamba mpaka pakati. Malo ogwirira ntchito ofunikira amagwiritsa ntchito ukadaulo wowotcherera wosagwira ntchito kapena ukadaulo wolimbitsa laser, zomwe zimapangitsa kuti kuuma kwa pamwamba pakhale HRC 50-55 kapena kupitirira apo. Izi zimalimbana bwino ndi kuwonongeka kwakukulu ndi kuwonongeka kwakukulu kuchokera ku zinthu zolimba monga miyala ndi mizu ya mitengo, zomwe zimawonjezera nthawi yogwira ntchito ndi nthawi 2-3 poyerekeza ndi pulawo wamba wa mbale zachitsulo ndikuchepetsa kwambiri kuchuluka kwa kusinthidwa m'munda.

Timagwiritsa ntchito kapangidwe ka pamwamba kopindika bwino, kotsatira mfundo za dothi. Kapangidwe kameneka kamapereka ubwino waukulu katatu:

1. Kuchotsa nthaka bwino kwambiri: Kupindika kwa malo opindika kumawerengedwa bwino kuti zitsimikizire kuti zibulunga za nthaka zitha kuchotsedwa nthawi yomweyo pamene zikukwera ndi kutembenuka, zomwe zimapangitsa kuti zikhale zoyenera kwambiri pa nthaka ya dongo komanso malo ogwirira ntchito omwe ali ndi chinyezi chambiri. Zimathandiza kuti nthaka isamamatire ndi kutsekeka, zomwe zimapangitsa kuti malo opumulirako akhale oyera.

2、Kusunga mphamvu kofunikira: Kupindika kwa chitsogozo chokonzedwa bwino kumachepetsa kukana kukangana pakati pa nthaka ndi pulawo, kumachepetsa bwino kukana kwa thirakitala ndi 10%-15% pamlingo womwewo wa ulimi ndi liwiro lomwelo, motero kuchepetsa kugwiritsa ntchito mafuta.

3. Kugwira bwino ntchito yothira feteleza: Kumatha kutembenuza udzu, ziputu, ndi feteleza molondola, kuzikwirira pansi pa nthaka, zomwe zimapangitsa kuti zinthu zachilengedwe ziwole ndikupanga malo obzala mbewu osalala komanso oyera kuti abzalidwe pambuyo pake.

Mapulawo osiyanasiyana amapereka njira ziwiri: kumaliza ndi galasi (koyenera mapulawo othamanga kwambiri) ndi kumaliza ndi slatted (koyenera dothi lolemera la dothi), kuphimba mapulawo osinthika, mapulawo odulidwa, ndi mapulawo opachikidwa pamsika. Zogulitsazi zimagwiritsa ntchito mabowo okhazikika a bolt kuti zikhale zosavuta kuyika komanso kusinthana kwambiri. Kuphatikiza apo, titha kupereka njira zosinthira curvature kutengera mphamvu ya thirakitala ndi mtundu wa nthaka zomwe kasitomala amapereka.
