Disc Harrow Nereza
Madhisiki eharrow ane corrugated (anozivikanwawo semadhisiki eharrow ane notched disc kana kuti madhisiki eharrow ane corrugated harrow) ndiwo madhisiki ekupfeka anoshandiswa mumichina yekurima yemazuva ano, anonyanya kushandiswa mukugadzira madhisiki makuru, michina yekudyara pamwe chete, uye kugadzira mbeu dzakanyatsogadzirwa. Chigadzirwa ichi chine dhizaini yakasarudzika ye corrugated edge uye tekinoroji yepamusoro yekurapa kupisa, zvichiita kuti ivhu riputswe zvakanaka ukuwo zvichideredza zvakanyanya kusimba kwekushanda. Chinhu chakakosha uye chakakodzera pakurima nekuchengetedza zvirimwa.
Chigadzirwa ichi chinoshandisa simbi ine manganese yakawanda ye65Mn kana 30MnB ine simba guru reboron sechigadziko uye chinoumbwa ne stamping inodziya zvakanyanya. Kuti tive nechokwadi chekuti inodzivirira kupfekwa zvakanaka uye inodzivirira kukuvadzwa, tinoshandisa tambo yekugadzira kupisa inodzorwa otomatiki kuti tiite kurapa kwe isothermal quenching uye surface carburizing, kuitira kuti kuomarara kwepamusoro kwemashizha erake kusvike HRC 38-45, nepo core ichiramba yakasimba. Kana tichienzanisa nema brake akajairwa, hupenyu hwayo hwekupfekwa hunowedzerwa neanopfuura 30%, zvichidzivirira kutsemuka uye kutenderera kwemashizha painoshanda muvhu rejecha.
Kusiyana nemadhisiki akatsetseka echinyakare, mashizha ereki ane mafungu ane mafungu akakura uye akadzika ane mafungu 4-10 akapararira zvakaenzana. Geometry iyi ine mabhenefiti matatu makuru:
Simba guru rekucheka: Mupendero wekucheka une mafungu unogadzira simba rekupwanya "rakaita serondedzero", uchicheka zviri nyore madzinde ezvirimwa nemasora, uye unopinda muzvikamu zvakaoma, zvakamanikana, zvichigadzirisa zvinobudirira matambudziko "anotsvedza" uye "anonetsa kupinda" ezvishandiso zvekucheka madhisiki zvechinyakare pazvinoshanda muvhu revhu rakaoma kana minda ine huswa hwakawanda.
Kusanganisa kwakafanana: Panguva yekutenderera, mupendero une mafungu unogadzira simba rakasimba rekukanda ivhu padivi, zvichiita kuti huswa nevhu zvisanganiswe zvakanaka, zvichidzivirira kuumbwa kwe "nzvimbo dzakaoma dzakasanganiswa," uye zvichiita kuti minda yembeu ive yakachena yekudyara mushure mezvo.
Inozvichenesa uye inodzivirira kuvhara: Nzvimbo yakasiyana-siyana yekuchinja yakaita searc inodzivirira ivhu rakanyorova, zvichiita kuti igare ichikwanisa kufamba zvakanaka kunyangwe munguva yekunaya kwemvura.
Kurima kwekuchengetedza muminda yakaoma: Kubvisa mashanga, kurima kusina kudzika, uye kusanganisa mashanga mushure mekukohwa zvirimwa zvakaita sechibage, gorosi, nesoya;
Ivhu rakawanda nevhu rakamanikana: Kupwanya gomba regejo kuti ivhu ripinde zvakanaka uye mvura ipinde zvakanaka;
Kurima kukuru kwepurazi: Sechikamu chekutanga chekurima chemuchina wekurima wakabatanidzwa, zvichiita kuti pave nekushanda kwakanaka kwazvo "kwekupfuura kamwe chete".
Mashandisirwo uye Kugadzirisa: Panguva yekuisa, iva nechokwadi chekuti nzvimbo iri pakati pemabhurazi eharrow ari pedyo inosangana nezvinodiwa zvekurima uye shandisa mabhaudhi ekusimbisa ane simba rakawanda. Zvinokurudzirwa kugara uchitarisa kupera kwemucheto wecutterhead. Kana radius yekusakara pamucheto wekucheka yadarika 3mm, itsive nekukurumidza kuti uve nechokwadi chekuti kurima kwakadzika nguva dzose uye kuti ivhu rinopwanyika.
