Foshoro yemuchina wepasi pevhu, muromo wegejo wakaita seV, Zvikamu zvemichina yekurima

Tsananguro pfupi:

Chigadzirwa chesimbi chinodzivirira kupfekwa chine ruvara rutema, foshoro yakapinza yakaita seV

Chimiro chine maburi maviri ekuisira. Inodzivirira kupera simba

chikamu chemichina yekurima yakaita semichina yepasi pevhu uye michina inotenderera,

inoshandiswa pakurima zvakadzika uye kusunungura ivhu.

Ruzivo rweChigadzirwa

Matagi eChigadzirwa

1. Kurima kwakadzika: Putsai poto yegejo, sunungurai ivhu rakadzika, vandudzai kupinza kwemhepo muvhu uye kugona kuchengetedza mvura.

2. Kugadzirira ivhu: Sunungura uye pwanya ivhu kuti pave nemamiriro ezvinhu akanaka ekudyara nekukudza mhodzi.

3. Kushandiswa kwemichina yekurima: Yakaiswa pamichina yepasi pevhu, michina inotenderera, nezvimwewo,

kurima zvakadzika muminda, minda yemichero nedzimwe nzvimbo.

Foshoro yemuchina wepasi pevhu, muromo wegejo wakaita seV, Zvikamu zvemichina yekurima

Chigadzirwa ichi chakagadzirwa nezvinhu zvine simba guru zvakaita sesimbi yemanganese ye65Mn uye simbi yeboron ye30MnB, uye chinoumbwa nekupisa, zvichiita kuti chimiro chemukati chive chakasimba uye kubvisa maburi ejecha nematambudziko anowanzoonekwa muma castings. Zvadaro, kuburikidza nekudzimwa kwemvura uye tempering heat treatment processes, kuomarara kweganda regejo kunosvika HRC 38-45, nepo core ichiramba yakasimba. Hunhu uhwu "hwakaoma kunze uye hwakasimba mukati" hunoibvumira kutsungirira kukuvadzwa kwakanyanya kubva kumatombo nemidzi yemiti (isina kutyoka) uye kuchengetedza mupendero wakapinza kwenguva yakareba, zvichiwedzera zvakanyanya kutenderera kwekutsiva.

1、Kugadzirwa kwenzvimbo yakakombama kwakarongeka: Takagadzirisa kona yekucheka nekukombama kwebanga regejo. Dhizaini iyi inoderedza kunamatira kwevhu zvinobudirira, inoderedza kuramba kurimwa ne15%-20%, nokudaro ichichengetedza kushandiswa kwemafuta etrakita uye ichivandudza kushanda zvakanaka.

2、Tekinoroji yekuzvirodza: Pamipendero yekucheka yakasakara zvakanyanya, tinoshandisa chiyero chakakosha chezvinhu. Pakushandisa, nzvimbo yekushanda yebanga regejo inova nemhedzisiro ye "kuzvirodza" pachayo, ichichengetedza mupendero wekucheka wakapinza nguva dzose uye ichidzivirira "kudhonza" kunokonzerwa nekuomarara. Izvi zvinoita kuti banga ritenderere zvakanaka uye rivharwe zvakasimba.

3、Kuisa kwakanyatsogadzirwa: Mafuru anogadzirwa zvinoenderana nezvinodiwa zvefekitori, nzvimbo yekuiswa kwemaburi uye kushivirira kwenzvimbo zvinodzorwa mukati mechikamu chidiki kwazvo, zvichiita kuti zvive nyore 100% kuenderana nekoramu yegejo negejo. Izvi hazvingorerutsi maitiro ekuisa chete asiwo zvinodzivirira kusunungura bhoti kana kushanduka kwebanga kunokonzerwa nemaburi akawandisa.

Magejo aya anowirirana zvakanyanya nemidziyo yakasiyana-siyana yekurima yakaita semagejo emapuranga emhando ye "moldboard", magejo anodzoserwa, uye madhishi. Ingave ichishandiswa pakusunungura zvakadzama uye kurima mushure mekukohwa kana kupwanya ivhu nekugadzirira usati wadyara, inoratidza kuchinjika kwakanyanya. Yakakodzera zvakanyanya mamiriro akasiyana-siyana akaomarara munzvimbo dzakadai senzvimbo yevhu dema yeNortheast China, nzvimbo ine jecha reNorthwest China, uye nzvimbo yevhu tsvuku yeSouthern China.
