Theridgerimhando yemichina yekurima, iyo inoshandiswa kune ridge yeminda yekurima uye levees, iri nyore uye nekukurumidza, kuchengetedza akawanda evashandi uye zviwanikwa zvenyama, uye ndeimwe yemichina yekurima yekurima, mvura uye masango.
Paddy kukwira mumundachinhu chakakosha chinongedzo mukugadzira mupunga.Kwenguva yakareba, paddy field ridging yakavakwa nemaoko nemamwe maturusi ekushanda, ane simba rakaderera, unhu husina kunaka, basa rakaoma uye mari yakakwirira, iyo inobata zvakananga kugadzirwa kwemupunga.Nokudaro, nzira yakanakisisa yekugadziramupunga wemunda wemupungandeye kushandisa paddy munda yakakosha ditching uye ridge muchina.
Chimiro chikuru uye basa rechikamu chimwe nechimwe
① Chimiro chikuru.Chimiro chemunda wepaddy yakakosha ditching uyekurira muchinainoratidzwa mumufananidzo.Muchina uyu unonyanya kuumbwa nezvikamu zvinomwe: furemu, kumiswa furemu, kutenderera kuchekwa, ditching mudziyo, kutyaira chikamu, hwamanda yekugadzira mudziyo uye kureba kugadzirisa.
② Basa rechikamu chimwe nechimwe.Basa reiyo furemu uye suspension furemu: furemu yakabatana neyakaturika furemu, iyo inoshandiswa kutsigira huremu hwemuchina wese uye yakabatana nekumisa tirakita.Basa remucheki weround: (1) cheka ivhu uye kuputsa ivhu, kuitira kuti ivhu rive rakatsetseka;(2) Cheka uswa nemasora, hazvidi kuti ubvise masora munzvimbo yekushanda, unogona kuvaka ridge operation, kuvaka ridge yakasimba.
③ Basa rekuita ditching uye ditching mudziyo.(1) kudonha;(2) Foshora ivhu, nepamativi maviri egejo muviri padama ivhu kutakura kusvika pakati nepakati nyanga yakaita ridge;(3) Migero miviri yakadonha kumativi ose emugodhi.
Iyo yekufambisa chikamu inonyanya kufambiswa kuburikidza nekubatanidzwa kwegiya kufambisa uye cheni kufambisa.Bhokisi regiya rinonyanya kuumbwa nebhokisi rekuvhara, bhokisi, giya rekutyaira, rinotyairwa bevel giya, chigaro chekutakura, nezvimwe. Iyo cheni yekufambisa chikamu inonyanya kuumbwa nekutyaira sprocket, inotyairwa sprocket uye cheni.
⑤ Basa rekuumba nyanga.Murwi wacho unokwidziridzwa kuita mutsetse we trapezoidal wakamanikana kumusoro uye wakafara kuzasi, uye wakapetwa kuti uvake goko.
⑥ Basa rekukwirira kugadzirisa mudziyo.Kureba uye kusimba kweiyo trapezoidal ridge upamhi uye ridge inodzorwa nekugadziriswa sikururu yehurefu hwekugadzirisa mudziyo.Kana iyo ridge yakanyanyisa uye yakatetepa, kugadzirisa kaviri nut inodzikiswa uye reverse inosimudzwa.
