Izixhobo zokulima ezenziwe ngokwezifiso ezikumgangatho ophezulu
I-plowshare, ekwaziwa ngokuba yi-plow blade okanye i-shovel tip, yinxalenye enokuguguleka nokungagugi efakwe phambi kwe-blade esezantsi yomzimba we-plow. Ngexesha lokusebenza, inqumla ngqo emhlabeni, ngokuyintloko isebenza ukunqumla umhlaba nokukhusela i-plowshare ephambili. Isiphelo sayo esibukhali sangaphambili sinciphisa ngempumelelo ukumelana, ngelixa i-alloy steel forging okanye i-casting enganyangekiyo isetyenziswa rhoqo ukumelana nokungqubana okukhulu komhlaba kunye namatye. Njengenxalenye eyintloko edibanisa umhlaba, ubukhali bayo kunye nokumelana nokuguguleka kuchaphazela ngokuthe ngqo ukuzinza kobunzulu bokulima kunye nokusetyenziswa kwepetroli, nto leyo ebangela ukuba kutshintshwe rhoqo.
Ngexesha lokulima, incam yekhuba ivelisa ngokuthe ngqo ukungqubana okunamandla kunye nefuthe lesanti, igrabile, kunye neengcambu zezityalo emhlabeni, nto leyo eyenza ukuba ibe yeyona nto igugileyo ngokukhawuleza kuyo yonke ikhuba. Ukusebenza kwayo kumisela ngokuthe ngqo umgangatho womhlaba wokulima kunye nokusetyenziswa kwepetroli. Incam yekhuba esemgangathweni ophezulu ingahlala igcina i-engile ebukhali yokungena, inciphisa kakhulu ukumelana nokutsala, inceda itrektara ukuba yonge amafutha, ngelixa iqinisekisa ubunzulu bokulima obuzinzileyo kunye nokugquma okuqinileyo. Ngokwahlukileyo koko, iincam zekhuba ezigugileyo nezibuthuntu zinokukhokelela kubunzima bokungena emhlabeni, ubunzulu bokulima obungaphantsi, ukusetyenziswa kwepetroli okuphezulu, kwaye kuchaphazele umgangatho wokuhlwayela okulandelayo.
Iingcebiso ze-plow zanamhlanje ezikumgangatho ophezulu zihlala zenziwe ngentsimbi ye-boron okanye intsimbi engagugiyo ene-alloy eninzi. Zenziwe ngeenkqubo zokubumba okanye zokubumba ngokuchanekileyo, kwaye ziphantsi koxinzelelo oluqinileyo lwe-isothermal okanye unyango lokunciphisa, isakhiwo se-metallographic sidityaniswe nobunzima obuphezulu kunye nokuqina okuhle - i-blade iqinile kwaye ayigugi, kwaye umqolo uqinile kwaye awugugi. Ezinye iimveliso eziphezulu zikwanayo nomaleko we-tungsten carbide alloy obekwe phezu komhlaba ukwenza isiphumo se-blade yokuzigaya, egcina incam ye-plow ibukhali ngexesha lokugugiswa.
Ukukhetha incam yokulima kufuneka kuhambelane ngqo nomzekelo womzimba wokulima, kwaye izinto ezifanelekileyo kunye nobukhulu kufuneka kukhethwe ngokusekelwe kwiimeko zomhlaba (umhlaba onesihlabathi, udongwe, umhlaba wegrabile). Ukuhlolwa rhoqo kunye nokutshintshwa kwangethuba kweencam zokulima ezigugileyo ngamanyathelo obulumko okukhusela umzimba wokulima kunye nokugcina imisebenzi esebenzayo nengabizi kakhulu.
Ngamafutshane, esi 'sikhonkwane sentsimbi' esingabonakaliyo, esinombingelelo waso ongagugiyo, sikhusela intliziyo yezixhobo zezolimo kwaye sixhasa inkqubo yokuqala neyona ibalulekileyo kwintsimi.
