Nsonga za pulawo ya tiller yosatha, magawo a tiller ozungulira, masamba a tiller ozungulira

Kufotokozera Kwachidule:

Nsonga ya pulawo ndi gawo losawonongeka komanso logwiritsidwa ntchito lomwe limayikidwa kutsogolo kwa thupi lalikulu la pulawo. Pakagwiritsidwa ntchito, limalowa m'nthaka isanayambe pulawo, lomwe limathandiza kudula ndikuswa nthaka ndikuteteza nsonga ya tsamba la pulawo. Limapangidwa kuchokera ku chitsulo cha boron kapena alloy chomwe sichiwonongeka kwambiri, chomwe chili ndi kuuma komanso kulimba kwabwino. Kapangidwe kake kosalala kamachepetsa kukana kwa nthaka ndipo kamathandizira kwambiri kulima bwino. Monga gawo logwiritsidwa ntchito, kusintha nsonga ya pulawo nthawi zonse kumawonjezera moyo wa ntchito ya thupi lalikulu la pulawo ndikuchepetsa ndalama zogwirira ntchito.

Chogulitsachi ndi chinthu chapakati, chomwe chimawonongeka mosavuta chomwe chimagwiritsidwa ntchito ndi mapulawu a moldboard, mapulawu osinthika, ndi ma subsoil, omwe amadziwika kuti "nsonga ya pulawu." Monga gawo lomwe limakhudza nthaka mwachindunji, limagwira ntchito zofunika kwambiri pakuswa, kulowa, ndi kutsogolera nthaka.

Nsonga ya pulawo iyi imapangidwa ndi chitsulo chapadera cha alloy boron (monga 65Mn kapena 60Si2Mn) pogwiritsa ntchito kupangira ndi kupondaponda kolondola kwambiri, komwe kumakhala kolimba kwambiri komanso kolimba bwino. Mphepete mwa pulawo imadutsa mu njira yapadera yochizira kutentha, zomwe zimapangitsa kuti ikhale yolimba ngakhale mu nthaka yolimba ya miyala kapena yomata, yopapatiza, zomwe zimachepetsa kwambiri kukana kulima ndikuwongolera kugwiritsa ntchito mafuta a thirakitala.

Kapangidwe ka chinthuchi kamatsatira kwambiri mfundo zoyendetsera mpweya. Kapangidwe kake kowongoka komanso kopindika sikuti kamangothandiza kutembenuza ndi kuphimba nthaka mbali imodzi komanso kumachepetsa kumatirira kwa nthaka, zomwe zimapangitsa kuti ulimi ugwire bwino ntchito. Mabowo omangira amapangidwa mwaluso kwambiri, zomwe zimapangitsa kuti nthakayo igwirizane bwino ndi maziko oyambira a pulawo, zomwe zimapangitsa kuti m'malo mwake mukhale osavuta komanso okhazikika popanda kugwedezeka.

Poyerekeza ndi zida wamba zachitsulo, nsonga iyi ya pulawo imakhala ndi mphamvu yolimba yolimbana ndi kuwonongeka kowirikiza katatu kapena kasanu, zomwe zimachepetsa kwambiri nthawi yogwira ntchito chifukwa cha kusintha kwa zida pafupipafupi. Ndi chisankho chabwino kwambiri pokonzekera bwino malo muulimi wamakono. Yoyenera mikhalidwe yosiyanasiyana yovuta, kuphatikizapo malo ouma, minda ya mpunga, ndi kukonzanso nthaka.

Zida zoyambira zogwirira ntchito zaulimi monga ma rotary tillers ndi ma moldboard plaws zimapangidwa ndi chitsulo chapamwamba kwambiri cha manganese alloy kapena boron steel chosatha kutha pogwiritsa ntchito forging yotentha kwambiri komanso stamping molondola. Kapangidwe kawo kopangidwa mwasayansi komanso m'mbali zakuthwa zodulira zimapereka ngodya zabwino kwambiri zolowera m'nthaka komanso kudzinola, zomwe zimachepetsa bwino kukana kulima ndikuwonjezera magwiridwe antchito. Kudzera mu njira yapadera yochizira kutentha, chinthuchi chimapeza mgwirizano wabwino pakati pa kuuma ndi kulimba, chokhala ndi kukana kuvula bwino komanso kukana kusweka. Ngakhale chikagwiritsidwa ntchito mu loam kapena miyala yolimba, chimawonjezera nthawi yogwirira ntchito ndikuchepetsa kuchuluka kwa ntchito, zomwe zimapangitsa kuti chikhale chofunikira kwambiri poteteza makina akuluakulu aulimi ndikuwonetsetsa kuti ulimi ukuyenda bwino.
