Waukulu dongosolo la ridger.

Themzererndi makina amtundu waulimi, omwe amagwiritsidwa ntchito pamphepete mwa minda ndi ma levees, yabwino komanso yachangu, yopulumutsa anthu ambiri komanso zinthu zakuthupi, ndipo ndi imodzi mwamakina olima ulimi, madzi ndi nkhalango.

Padi padi padindi ulalo wofunikira pakupanga mpunga.Kwa nthawi yayitali, kukwera kwa paddy kumamangidwa ndi manja ndi zida zina zogwirira ntchito, zomwe zimakhala ndi mphamvu zochepa, zopanda ntchito, ntchito zovuta komanso mtengo wokwera, zomwe zimakhudza mwachindunji kupanga mpunga.Choncho, njira yabwino kumangampunga wamundandikugwiritsa ntchito paddy field special ditching and ridge machine.

Mapangidwe akuluakulu ndi ntchito ya gawo lililonse

① Kapangidwe kake.Kapangidwe ka paddy munda wapadera ditching ndimakina osindikizirachikuwonetsedwa pachithunzichi.Makinawa amapangidwa makamaka ndi magawo 7: chimango, chimango choyimitsidwa, chodulira chozungulira, chida cholowera, gawo loyendetsa, chipangizo chopangira lipenga ndi chipangizo chosinthira kutalika.

② Ntchito ya gawo lililonse.Ntchito ya chimango ndi kuyimitsidwa chimango: chimango cholumikizidwa ndi chimango kuyimitsidwa, chimene chimagwiritsidwa ntchito kuthandizira kulemera kwa makina onse ndipo chikugwirizana ndi kuyimitsidwa thirakitala.Ntchito ya wodula mozungulira: (1) kudula dothi ndikuphwanya nthaka, kuti nthaka ikhale yosalala;(2) Dulani udzu ndi namsongole, osafunikira kuchotsa udzu pamalo ogwirira ntchito, mutha kupanga ntchito yopangira zingwe, kumanga phiri lolimba.

③ Ntchito yolowera ndi kugwetsa chipangizo.(1) kugwa;(2) Fosholoni m'nthaka, kudutsa mbali ziwiri za khasu thupi tsaya m'nthaka zoyendera mpaka pakati nyanga zooneka lokwera;(3) Ngalande ziŵiri zinagwera mbali zonse za chitundacho.

Gawo lopatsirana limapatsirana makamaka kudzera pakuphatikizana kwa zida ndi kufalitsa unyolo.Bokosi la gear limapangidwa makamaka ndi chivundikiro cha bokosi, bokosi, zida zoyendetsera galimoto, zida zoyendetsedwa ndi bevel, mpando wonyamula, etc. Gawo lotumizira unyolo limapangidwa makamaka ndi sprocket yoyendetsa, sprocket yoyendetsedwa ndi unyolo.

⑤ Ntchito ya chipangizo chopangira nyanga.Mphepete mwa chulucho imatuluka mumtunda wa trapezoidal wopapatiza pamwamba ndi waukulu pansi, ndikumangika kuti amange phirilo.

⑥ Ntchito ya chipangizo chosinthira kutalika.Kutalika ndi kulimba kwa mtunda wa trapezoidal ndi m'lifupi zimayendetsedwa ndi kusintha kwa screw kwa chipangizo chosinthira kutalika.Ngati phirilo ndi lalitali kwambiri komanso lopapatiza kwambiri, kusintha kwa mtedza wawiri kumatsitsidwa ndipo chotsaliracho chimakwezedwa.
