Mabala a pulawu olimba kwambiri, zida zogwirira ntchito zamakina a ulimi, kuyeretsa nthaka ndi masamba oswa nthaka Chithunzi Chowonetsedwa

Masamba a pulawo olimba kwambiri, zida zogwirira ntchito zamakina a ulimi, kukonza nthaka ndi masamba a pulawo osweka nthaka

Kufotokozera Kwachidule:

Tsamba la pulawo, lomwe ndi chowonjezera cha makina a ulimi, limapangidwa ndi chitsulo champhamvu kwambiri komanso chosatha. Mphepete mwake mumakhala ndi chithandizo chapadera cha kutentha, zomwe zimapangitsa kuti likhale ndi malo akuthwa komanso olimba omwe salola nthaka kulowa komanso nthaka kusweka bwino. Lili loyenera kulima mozama m'malo osiyanasiyana a nthaka, limadula mizu ya udzu bwino ndikuchotsa makoma a nthaka. Lili losavuta kuyika komanso losinthasintha kwambiri, ndi loyenera kulowa m'malo mwa thirakitala ndi makina a ulimi, zomwe zimapangitsa kuti ulimi ugwire bwino ntchito komanso kuti nthaka ikhale yabwino.

Tsamba lolimba la pulawo lomwe limagwiritsidwa ntchito limodzi ndi makina a zaulimi limapangidwa ndi mbale yachitsulo yamphamvu kwambiri ya 65Mn kudzera mu njira yokhazikika yopopera ndi kulimbitsa kutentha. Ndi yoyenera mitundu yosiyanasiyana ya mapulawo a bolodi louma, mapulawo osinthika ndi mapulawo ochotsera nthaka ndi makina ena olima. Ndi gawo lofunika kwambiri logwira ntchito yolima nthaka.

Tsamba la pulawo limapangidwa ndi chitsulo cha manganese cha 65Mn kapena chitsulo cha boron cha 30MnB2 (ngati mukufuna), ndipo limapangidwa kudzera m'njira zosiyanasiyana kuphatikizapo kupukuta, kutentha, kupangira die, kudula m'mphepete, ndi kuwongola. Mphepete mwachitsulocho imachizidwa ndi njira yozimitsira, zomwe zimapangitsa kuti ikhale yolimba ngati HRC45-52, pomwe imakhala yolimba kumbuyo. Ili ndi mphamvu zambiri komanso kukana kukhudza kwambiri. Pamwamba pake pakhoza kuphimbidwa ndi ufa kapena kufiyidwa kuti pasakhale dzimbiri, zomwe zimapangitsa kuti pakhale kukana kwa nyengo.

Chogulitsachi chili ndi mawonekedwe a triangle kapena mutu wa muvi wokhala ndi ngodya yakuthwa yolowera kutsogolo. Mphepete mwa m'mphepete mwachitsulochi imakonzedwa bwino kutengera momwe nthaka imagwirira ntchito, zomwe zimachepetsa kukana kwa kugwedezeka ndi 15%-20%. Kumbuyo kuli mabowo omangirira ndi mabowo a bolt kuti alumikizane bwino ndi khoma la pulawo ndi pulawo, zomwe zimathandiza kuti zikhale zosavuta kusonkhanitsa ndi kumasula. Mitundu ina yawonjezera nthiti zolimbitsa kumbuyo, zomwe zimapangitsa kuti zikhale zoyenera dothi la miyala kapena lolemera la dongo.

Kusawonongeka kwambiri: Nthawi yogwira ntchito ya tsamba imatha kufika 300-500 mu/chidutswa (kutengera mtundu wa nthaka), nthawi yayitali kuposa mapulawu wamba a carbon steel.

Kudzinola Kokha: Malo ogwirira ntchito amagwiritsa ntchito kapangidwe kosiyana ka kuuma, komwe kamasunga kuuma kwa tsamba panthawi yolima, ndikuchotsa kufunikira konola pafupipafupi.

Kusweka bwino kwa nthaka ndi kumasula nthaka: Malo ogwirira ntchito opindika pamodzi ndi kupukuta galasi zimathandiza kuti nthaka idutse bwino, zomwe zimapangitsa kuti nthaka isamamatire bwino komanso kuti iphimbe bwino.

Kusinthasintha kwakukulu: Kuyika malo olumikizira mabowo kumatha kusinthidwa malinga ndi zojambula zoyambirira kapena zitsanzo zomwe ogwiritsa ntchito amapereka, zogwirizana ndi ma plau odziwika bwino ochokera kuzinthu monga Recon, Gran, ndi Kuhn.

Imagwiritsidwa ntchito kwambiri kulima mbewu zouma monga chimanga, tirigu, ndi soya, komanso pazovuta monga nthaka yatsopano, nthaka yolimba, ndi mchenga. Ndikofunikira kuyang'ana kuwonongeka kwa m'mphepete mwa ntchito iliyonse ya 200 mu (pafupifupi mahekitala 33). Ngati kuwonongekako kupitirira 15mm, isintheni mwachangu kuti muwonetsetse kuti ikukula bwino.
