Izesekeli zokulima ezinamandla aphezulu: i-plowshare

Incazelo emfushane:

Ama-plow blades ayizingxenye zemishini yezolimo ezinembile kakhulu, ezingagugi eziklanyelwe ngqo ukukhiqizwa kwezolimo zanamuhla. Afaneleka ama-moldboard amakhulu, aphakathi nendawo, namancane kanye nama-plow aguqulwayo. Njengengxenye eyinhloko yokuxhumana nenhlabathi ethinta ngqo inhlabathi, inquma ngqo ukujula kokulima, umphumela wokujika kwenhlabathi, kanye nokonga uphethiloli wethrakhi. Sisebenzisa insimbi ye-manganese ephezulu noma insimbi yesipili engu-65Mn, ehlanganiswe nezinqubo zokulungisa ngokunemba kanye nokushisa, ukuqinisekisa ukuthi i-plow blade ngayinye inobunzima obukhulu kakhulu, ukumelana nokuguguleka okuhle kakhulu, kanye nokuqina okuhle komthelela, okwenza kube ukukhetha okuhle kakhulu kokulima okujulile kanye nemisebenzi yokubuyisela utshani.

I-blade yokulima, ingxenye esekelayo yemishini yezolimo, iyingxenye ebalulekile yokusebenza efakwe emzimbeni we-plow, evame ukwenziwa ngensimbi ephezulu ye-manganese noma insimbi ye-boron ngokuyicima nokuyibumba. Imisebenzi yayo eyinhloko ukusika inhlabathi, ukuphakamisa ama-clod, nokuphula ama-clod enhlabathi. Isihloko se-blade ebukhali sinciphisa ngempumelelo ukumelana nokulima, futhi umklamo we-blade omelana nokuguguleka wandisa kakhulu impilo yayo yesevisi. Ifanelekela ukulima ezindaweni ezomile futhi ingathuthukisa kakhulu ukusebenza kahle kanye nekhwalithi yokulima.

I-plowshare yenziwe ngensimbi ye-manganese alloy ephezulu enesilinganiso esenziwe ngokwezifiso, esiqinisa ngokushesha indawo ngaphansi kokushaywa okukhulu noma ukucindezeleka okukhulu kokuthintana, sakha ungqimba oluqinile kakhulu olungagugi ngenkathi sigcina ukuqina okuhle kakhulu ngaphakathi. Lesi sici "sokuqina ebusweni nangaphakathi" sithuthukisa ukumelana nokuguguleka ngo-30%-50% uma kuqhathaniswa nemikhiqizo evamile ezimweni ezinzima njengendawo yesihlabathi nendawo ehlanganisiwe, kunciphisa ngempumelelo isikhathi sokungasebenzi esibangelwa ukushintshwa kwezingxenye njalo.

I-engeli yokungena ye-ploughshare kanye ne-blade tip curve kulungiselelwe ngokuhlaziywa kwe-CAE finite element, okuletha ikhono eliphezulu lokungena kwenhlabathi. I-blade tip ebukhali inqamula kalula izendlalelo ezihlanganisiwe, iqinisekisa ukuhlukana kwenhlabathi okuhle kakhulu ngenkathi inciphisa ukumelana nokulima. Lokhu kunciphisa kakhulu umthwalo wokudonsa i-tractor, kanye nokuhlolwa kwensimu okubonisa ukonga kukaphethiloli okungu-5%-8%, okunciphisa ngempumelelo izindleko zokusebenza kwemisebenzi yokulima enkulu.

Umklamo womkhiqizo unesakhiwo esiyingqayizivele somphetho ozilolayo. Ngesikhathi sokusebenza, ingxenye ye-plow blade ethinta inhlabathi iyaqhubeka nokuguga, kodwa ngenxa yokwehluka kokuminyana kwezinto kanye nobunzima phakathi kwezingxenye zangaphambili nezingemuva, i-plow blade igcina umphetho obukhali wokusika kulo lonke ukusetshenziswa, ivimbela isenzakalo "se-blow blade". Lokhu kuqinisekisa ukujula kokulima okuhambisanayo kanye nokugumbuqela inhlabathi okufanayo.

Ukulandela ngokuqinile amazinga kazwelonke (noma amazinga e-ISO) ekukhiqizeni, ngesikhala esiqondile semigodi yokufaka, okulungele iningi lezinhlangano zomzimba we-plow emakethe. Ngaphambi kokushiya ifektri, kwenziwa ukuhlolwa kwekhwalithi okuqinile ukuqinisekisa ukuthi azikho izimbobo noma ama-burrs aphukile. Izingxenye zokuqala zingashintshwa ngqo, kufezwe ukufakwa nokusetshenziswa ngokushesha ngaphandle kwesidingo sokucutshungulwa kwesibili.
