Zitsulo Zachitsulo Zapamwamba Zopangidwa ndi Chitsulo Chakutsogolo Chopangidwa ndi Chitsulo Chakutsogolo – Zida Zamakina Zaulimi Zopangira Chitsulo Chopangidwa ndi ...
Chomera chakutsogolo, chomwe ndi gawo lofunika kwambiri pa pulawo la moldboard, ndi gawo lofunika kwambiri pa ntchito yapakati. Nthawi zambiri chimagwira ntchito limodzi ndi pulawo yakumbuyo ndi pulawo kudula, kuswa, ndi kutembenuza nthaka. Ponena za zitsanzo 619127 ndi 619173 zomwe mwatchulazi, ngakhale zotsatira zakusaka sizinapereke mwachindunji zojambula zaukadaulo kapena magawo a manambala a zitsanzozi, kufotokozera mwatsatanetsatane kwa mtundu uwu wa pulawo yakutsogolo kungapangidwe kutengera miyezo yaukadaulo yamakina aulimi ndi mabuku ofanana ndi a patent motere:
Mapulawo akutsogolo a mitundu 619127 ndi 619173 amatsatira lingaliro la "modular" la mapulawo amakono a moldboard. Nthawi zambiri amamangiriridwa ku chogwirira cha pulawo ndi chogwirira cha pulawo pogwiritsa ntchito mabotolo amphamvu kwambiri. Kapangidwe kameneka sikuti kamangotsimikizira kukhazikika kwa kulumikizana komanso, chofunika kwambiri, kumathandiza kusintha ziwalo zomwe zimawonongeka mosavuta. Mu kapangidwe konse, mapulawo akutsogolo a mitundu iwiriyi ali pamwamba kapena kumbuyo kwa pulawo, ndikupanga malo athunthu a pulawo pamodzi ndi pulawo yakumbuyo.
Kulondola kwa malo otsetsereka: Kapangidwe ka pamwamba pa pulawo la kutsogolo ndi kofunika kwambiri pa ntchito yake. Kutengera ndi makhalidwe aukadaulo a pulawo la liwiro lalikulu, pulawo la kutsogolo ili (monga 619127 ndi 619173) nthawi zambiri limakhala ndi malo enaake ozungulira, ndipo m'mphepete mwake nthawi zambiri limapangidwa ngati khola lozungulira. Kapangidwe kameneka kamachepetsa kukana kwa kulima, kuonetsetsa kuti zibulumwa za nthaka zikukwera bwino, zimasweka, ndikukwaniritsa kugwa bwino ndi kuphimba pambuyo pokhudza pulawo, zomwe zimapangitsa kuti ikhale yoyenera kwambiri kulima mwachangu m'nthaka youma.
Kuchotsa bwino nthaka ndi kukana kuvala: Monga gawo lotha kutha, pulawo yakutsogolo imagwira ntchito m'mikhalidwe yovuta kwambiri, ikunyamula mwachindunji kukangana kwakukulu ndi kukhudza kwa nthaka. Nthawi zambiri, zinthu zotere zimagwiritsa ntchito chitsulo cha 65Mn kapena chitsulo china cholimba kwambiri ngati maziko, ndipo chimagwiritsa ntchito njira zotenthetsera kutentha (monga kulimbitsa) kuti chiwongolere kuuma kwake pamwamba ndi kukana kuvala, motero chimakulitsa nthawi yake yogwirira ntchito. Mapangidwe ena apamwamba amathanso kugwiritsa ntchito zinthu zamaginito, pogwiritsa ntchito mphamvu yamaginito kuti akonze mgwirizano wa nthaka, kuchepetsa kumamatira kwa nthaka, komanso kuchepetsa kukana kulima.
Ubwino wa gulu logawanika: Cholembera cha pulawo chapangidwa ngati gawo logawanika kutsogolo ndi kumbuyo (monga, gawo lakutsogolo ndi 619127, ndipo gawo lakumbuyo lofanana ndi chitsanzo china) makamaka kuti lithetse vuto la kusagwiritsidwa ntchito bwino. Pakugwira ntchito kwenikweni, nsonga ndi tsinde la pulawo lakutsogolo zimawonongeka mofulumira kwambiri kuposa gawo lakumbuyo. Kudzera mu kapangidwe kogawanika, pamene 619127 kapena 619173 iwonongeka pamlingo winawake, wogwiritsa ntchito amangofunika kusintha gawo lakutsogolo, kuchotsa kufunikira kotaya pulawo lonse, kuchepetsa kwambiri ndalama zokonzera ndi zinyalala za zinthu.
Mapulawo awiri akutsogolo nthawi zambiri amaikidwa pa mapulawo a moldboard kapena mapulawo osinthika mwachangu omwe amakokedwa ndi mathirakitala apakati mpaka akuluakulu. Chifukwa cha kapangidwe kawo kopindika bwino komanso kapangidwe kake kolimba, ndi oyenera kugwiritsidwa ntchito m'minda youma, dothi lolemera la dongo, ndi malo ovuta omwe amafunika ntchito zochotsera nthaka, kuonetsetsa kuti nthaka ikusweka bwino komanso ikuzungulira ngakhale pa liwiro lalikulu.
Kuti zitsimikizire kuti zinthuzo zikugwira ntchito bwino, chinthucho nthawi zambiri chimapangidwa pogwiritsa ntchito njira zoyezera kapena zopangira ma die kuti zitsimikizire kuti pamwamba pake pali kulondola komanso kusalala. Kenako chimayikidwa mu carburizing kapena quinched treatment kuti chitsimikizire kuti chimatha kuuma bwino komanso kuti chimateteza kuuma kwapakati, kupewa kusweka mukakumana ndi zopinga monga miyala kapena mizu ya mitengo.
