Masamba a rotary tiller, osatha ntchito komanso okhuthala, oyenera kulimidwa ndi kudulidwa kwa mipanda.

Kufotokozera Kwachidule:

Tsamba lotirira ili limapangidwa ndi chitsulo chokhuthala cha manganese cha 65Mn, chomwe chimapereka kuuma ndi kulimba kwabwino kwambiri, zomwe zimapangitsa kuti likhale lolimba komanso losasweka. Mphepete mwake yakuthwa imaswa mosavuta nthaka yolimba komanso yopapatiza, zomwe zimapangitsa kuti nthaka ikhale yolimba popanda kuphwanya udzu. Imagwirizana bwino ndi ma micro-tillers ndi ma rotary tillers, ndi chowonjezera chabwino kwambiri pakubwezeretsa nthaka m'malo ouma, kulima minda yamasamba, ndi kulima greenhouse.

Masamba a ulimi apamwamba awa amapangidwa ndi chitsulo chapamwamba kwambiri, chokhala ndi tsamba lotenthedwa bwino lomwe limateteza ku kuwonongeka kwambiri. Kapangidwe kake kasayansi kamaonetsetsa kuti ulimi ukukulirakulira, kuphimba bwino, komanso malo osalala komanso ofanana akagwiritsidwa ntchito. Amagwirizana ndi mitundu yosiyanasiyana ya makina a ulimi, amakhala olimba kwambiri, amalimbana ndi kusintha kwa kutentha, ndipo amachepetsa kugwiritsa ntchito mafuta moyenera, zomwe zimapangitsa kuti akhale chisankho chodalirika pa ntchito zaulimi zogwiritsidwa ntchito ndi makina.

1. Chitsulo cha alloy chapamwamba: Timasankha mosamala zitsulo zapadera zamasika zomwe zingagwiritsidwe ntchito pazinthu zogwira ntchito kwambiri komanso zogwiritsidwa ntchito kwambiri, makamaka kuphatikiza zitsulo zapamwamba kwambiri monga 60Si2Mn (60 silicon-manganese), 60Si2MnA, ndi 28MnSiB. Zipangizozi zili ndi zokolola zambiri komanso malire otanuka, zomwe zimawathandiza kuti azisunga thupi la chida popanda kusintha kapena kusweka chifukwa cha kugwedezeka kwakukulu komanso mphamvu yayikulu.

2、Ukadaulo wothira kutentha: Njira yozimitsira ya martensitic imagwiritsidwa ntchito, ndi kuwongolera mwamphamvu kutentha kwa kutentha ndi kuzizira kuti akwaniritse kapangidwe kabwino ka metallographic ka tsamba. Kuuma kwa chinthu chomalizidwa kumayendetsedwa bwino mkati mwa Rockwell hardness (HRC) ya 42-48, ndipo zina zimafika HRC45±3. Kuuma kumeneku kumatsimikizira kuti m'mphepete mwa tsambalo mutha kudula mosavuta dothi lolimba ndipo kumakhala ndi kukana kwabwino kwa kuwonongeka, pomwe kumasunga kulimba kokwanira kwa gawo la thupi la tsambalo kuti lisagwe.

Kubwezeretsa malo ouma: Ndi mphamvu yake yamphamvu yolowera m'nthaka, imatha kugwira ntchito mwachindunji pamalo ouma ouma, ndikuswa poto yolimba yopangira pulawo.

Kuletsa udzu ndi zitsamba: Masamba akuthwa amadula bwino mizu ya udzu yokhotakhota ndi tsinde laling'ono la zitsamba, kuteteza kutsekeka ndi kutsekeka.

Ntchito zambiri: Kuwonjezera pa kukonzanso malo otayirapo, ndi yoyeneranso kulima mozama, kudula mizati, ndi kudula udzu m'minda yokhwima, zomwe zimathandiza kwambiri komanso zimasinthasintha.
