Nsonga ya pulawo yaulimi ikhoza kusinthidwa, yoyenera kulima, fosholo, kutentha, zowonjezera zolimbitsa tiller

Kufotokozera Kwachidule:

Fosholo ya pulawo yaulimi ndiye chowonjezera chachikulu cholimira ndi kulinganiza chomwe chimagwiritsidwa ntchito limodzi ndi mathirakitala, nthawi zambiri chimayikidwa pansi pa thupi la pulawo. Chimapangidwa ndi chitsulo cha boron cholimba kwambiri chomwe sichimawonongeka ndipo chimachitidwa opaleshoni yapadera yotenthetsera kutentha, chokhala ndi ngodya zakuthwa zolowera komanso kukana bwino kuwonongeka. Pa ntchito yophunzira, imatha kudula bwino nthaka ndi zinyalala, kuchepetsa kukana kukoka, ndikuteteza thupi lalikulu la pulawo. Yoyenera kulima mozama komanso kugwira ntchito zozungulira nthaka m'malo osiyanasiyana monga minda youma, minda ya mpunga, ndi kubwezeretsa nthaka.

Fosholo ya pulawo, monga chowonjezera cha makina a ulimi a mathirakitala, ndi chinthu chofunikira kwambiri chomwe chimayikidwa pa thupi la pulawo kuti chipirire kuwonongeka kwa nthaka ndi kugundana. Kugwira ntchito kwake kumatsimikizira mwachindunji kuzama, kukhazikika, komanso kugwiritsa ntchito mafuta moyenera pa ulimi. Fawolo ndi fosholo yabwino kwambiri sizomwe zimangoyambitsa kuswa nthaka ndi kukumba ngalande, komanso maziko owonetsetsa kuti ntchito zaulimi zikuyenda bwino komanso mosalala.

Ponena za zipangizo ndi luso lapamwamba, mapulawu ndi mafosholo apamwamba nthawi zambiri amagwiritsa ntchito zitsulo zapamwamba kwambiri monga chitsulo cha manganese cha 65Mn kapena chitsulo cha spring cha 60Si2Mn ngati zinthu zomangira.

Zipangizozi zimakhala ndi mphamvu yokoka komanso nthawi yotopetsa, zomwe zimatha kukwaniritsa zosowa za ntchito zaulimi zomwe zimakhala ndi katundu wambiri komanso nthawi yayitali. Pofuna kupititsa patsogolo kukana kwake kuwonongeka komanso mphamvu zake, kupanga mapulawu ndi mafosholo nthawi zambiri kumagwiritsa ntchito njira yopangira kamodzi kokha, yomwe imamaliza mizere yachitsulo ndikuchotsa zolakwika zamkati kudzera mu kupangira kotentha kapena kupondaponda. Chopangidwacho chimafunikanso kuchitidwa chithandizo chotentha molondola (monga kuzimitsa kuti chikhale ndi kapangidwe ka martensitic), kotero kuti kuuma kwake nthawi zambiri kumayendetsedwa mkati mwa Rockwell hardness (HRC) 38 mpaka 50, potero kusunga kuuma kwakukulu komanso kukhala ndi kulimba kwabwino, kupewa kusweka kosalimba kapena kuwonongeka koyambirira panthawi yogwira ntchito.

Ponena za magwiridwe antchito ndi kapangidwe kake, mapulawu ndi mafosholo ndi oyenera kwambiri mapulawu apakati, mapulawu osagwira ntchito, ndi makina osiyanasiyana olima, ndipo amagwiritsidwa ntchito kwambiri m'malo osiyanasiyana ogwirira ntchito monga minda ya mpunga, malo ouma, ndi malo obwezeretsedwa. Kapangidwe kake nthawi zambiri kamakhala ndi m'mbali zakuthwa zodulira ndi ngodya zinazake zolowera, zomwe zimatha kudula mosavuta nthaka yolimba ndi mizu ya mbewu, ndikuchepetsa kukana kutsogolo. Malinga ndi zosowa zosiyanasiyana zaulimi, mitundu ndi zofunikira za mapulawu ndi mafosholo zimasiyanasiyana. Mwachitsanzo, pali mitundu yeniyeni ya mafosholo yomwe imagwiritsidwa ntchito makamaka pokweza mapiri ndi kuyika mipanda, yokhala ndi makulidwe kuyambira 5mm mpaka 8mm. M'lifupi ndi kutalika zimasiyananso malinga ndi kuzama kwa kulowa komwe kumafunika kuti kukwaniritse zofunikira zofanana za mathirakitala okhala ndi mphamvu zosiyanasiyana za akavalo ndi nthaka.

Pofuna kuzolowera malo ogwirira ntchito a misika yosiyanasiyana yapadziko lonse ndikuletsa dzimbiri, pamwamba pa mapulawu nthawi zambiri pamakhala mankhwala oletsa dzimbiri monga kupaka utoto, kupopera ufa (kupopera), kapena kupopera galvanizing. Magawo ochiritsira pamwamba awa samangopatsa chinthucho mawonekedwe ofanana (monga mitundu yakuda, yobiriwira, kapena yosinthidwa malinga ndi zosowa za makasitomala), komanso amachotsa chinyezi ndi zinthu zowononga, zomwe zimapangitsa kuti zinthuzo zisungidwe bwino komanso kuti zigwiritsidwe ntchito nthawi yayitali.

Kuphatikiza apo, opanga akatswiri nthawi zambiri amapereka ntchito zosinthira za OEM/ODM, zomwe zimatha kupanga zinthu zosakhazikika zokhala ndi malo otseguka, makulidwe kapena zinthu kutengera zojambula kapena zitsanzo zomwe makasitomala amapereka, kuonetsetsa kuti zayikidwa molondola komanso zogwirizana ndi mitundu yosiyanasiyana ya mathirakitala (monga Foton Lovol, John Deere, ndi zina zotero).

Mwachidule, zida zamakina a ulimi monga mapulawu ndi mafosholo ndi zinthu zomwe zimagwiritsidwa ntchito popanga zinthu zapamwamba, njira zamakono zochizira kutentha, komanso kapangidwe kolondola. Zimalowa mkati mwa nthaka kudzera mu "thupi" lake lolimba kuti zikwaniritse ntchito zophwanya, kuphwanya, ndi kutembenuza nthaka, zomwe ndi chitsimikizo chofunikira kwambiri pakuwonjezera kupanga ndi kupeza ndalama zaulimi.
