Ama-blade okulima aphethwe ngokushisa angu-60Si2Mn, ama-blade okulima okunzima, ama-blade okulima ajikelezayo okususa inhlabathi eqinile namagquma angenalutho, izesekeli zemishini yezolimo. Isithombe Esifakiwe

Ama-blade okulima aphathwe ngokushisa angu-60Si2Mn, ama-blade okulima okunzima, ama-blade okulima ajikelezayo okususa inhlabathi eqinile namagquma angenalutho, izesekeli zemishini yezolimo.

Incazelo emfushane:

I-blade yokulima yenziwe ngensimbi ye-alloy engagugi, enomkhawulo wokusika ophathwa ngokushisa ukuze kuqiniswe amandla. Ifanelekela ukulima kokuqala kwezwe eliyincithakalo, inhlabathi ehlanganisiwe, kanye nenhlabathi eqinile. Umklamo wayo oyingqayizivele ofana ne-arc noma i-chisel uphula ngempumelelo amagagasi enhlabathi kanye nezimpande zokhula, kunciphisa ukudonswa kwamandla kanye nokusetshenziswa kukaphethiloli. Ihambisana nama-rotary tillers ahlukahlukene kanye nemishini yokulima, kulula ukuyifaka futhi ithuthukisa kakhulu izinga lokuphuka kwenhlabathi kanye nokusebenza kahle komsebenzi, okwenza kube yinto eqinile yokuhlanza nokulungisa umhlaba wezolimo.

Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

Lo mkhiqizo uyi-blade yokulima enamandla amakhulu (eyaziwa nangokuthi i-blade yokuhlanza umhlaba) eyenzelwe ngqo ukulima kwezolimo. Njengesengezo esiyinhloko sama-rotary tillers nama-tractor, usetshenziswa kakhulu ekuvuseleleni amapulazi, ekuvuseleleni amahlane, ekusikeni utshani, kanye nasemisebenzini yokusika imisele. Wenzelwe ngqo ukubhekana nezimo zenhlabathi eziyinkimbinkimbi neziqinile, okwenza kube ukukhetha okuhle kokuthuthukisa isakhiwo senhlabathi nokuthuthukisa ukusebenza kahle kokulima.

Lo mkhiqizo uhlanganisa izimiso ze-mechanics kanye ne-geometry ekwakhiweni kwawo, ikakhulukazi equkethe izakhiwo ezimise okwe-C kanye ne-L. I-blade iqondile futhi inokuqina okuhle kakhulu. Umzimba we-blade uqukethe izingxenye ezimbili: isibambo kanye nesihloko se-blade.

Isibambo Sesilayidi: Sihlonyiswe ngemigodi emibili yokulungisa eqondile yokuxhuma okuphephile emishinini yezolimo, okuqinisekisa ukuthi ihlala izinzile futhi ayishintshi ngaphansi kwemithwalo yemfanelo esindayo.

Ikhanda Le-Blade: Lisebenzisa inqubo yokugoba efana ne-arc, okuhlanganisa kokubili ama-blade okusika ngaphambili kanye nama-side-cutting. I-arc yalo eyingqayizivele yokugoba (cishe i-119°-120°) kanye nokubeka ukuphakama kunciphisa ngempumelelo ukumelana lapho kunqunywa enhlabathini, okuholela ekuqhekekeni kwenhlabathi okungcono kanye nokujula kokusebenza okuhambisanayo.

Ukuze kuhlangatshezwane nezidingo zokumelana nokushayisana okunamandla aphezulu kanye nokumelana nokuguguleka, umzimba we-blade wenziwe ngezinto zensimbi zasentwasahlobo ezinokuqina okuphezulu njenge-60Si2Mn, 60Si2MnA, kanye ne-28MnSiB.

Ngemva kokwelashwa kokushisa okunzima (ukuguqulwa kwesigaba se-martensitic), ubulukhuni bomkhiqizo bulawulwa phakathi kwe-HRC 42 ne-48, okuqinisekisa ukuthi i-blade ayiphuki kalula noma ayifiphali ngaphansi komthelela omkhulu. Ngaphezu kwalokho, amanye amamodeli ane-hot-melt alloy coating ebusweni be-blade, engagcini nje ngokuthuthukisa ukumelana nokuguguleka kodwa futhi inomsebenzi "wokuzilola"—okungukuthi, igcina ubukhali bomphetho we-blade ngesikhathi sokuguguleka kokusebenza, inciphisa ukusetshenziswa kwamandla futhi ifinyelele ukonga amandla.

Lo mkhiqizo uhambisana kakhulu nama-tractor ahlukahlukene amakhulu naphakathi, futhi ufanelekela kakhulu ukubuyiselwa komhlaba, ukusika utshani obudala, kanye nokubeka imisele emathafeni, ezindaweni ezomile, kanye nasezintabeni ezithambile. Ungaphula ngempumelelo izingqimba zomhlabathi ezihlanganisiwe, wandise ukubhoboka kwenhlabathi, futhi unikeze indawo yokutshala imbewu ekhululekile nephefumulayo yokutshala izitshalo okulandelayo.
