Nyundo ndiye gawo lofunikira kwambiri komanso losavuta kuvala la chopondapo

Pakalipano, pali mitundu yambiri ya nyundo yomwe imagwiritsidwa ntchito, koma yomwe imagwiritsidwa ntchito kwambiri ndi nyundo yooneka ngati mbale yamakona anayi.Chifukwa cha mawonekedwe ake osavuta, kupanga kosavuta, komanso kusinthasintha kwabwino.

Chitsanzo chothandizira chili ndi mapini awiri a pini, imodzi yomwe ili ndi dzenje pamndandanda wa pini, yomwe imatha kuzunguliridwa kuti igwire ntchito ndi ngodya zinayi.Mbali yogwira ntchito imakutidwa ndi kuwotcherera ndi tungsten carbide kapena kuwotcherera ndi aloyi yapadera yosamva kuvala kuti atalikitse moyo wautumiki.

Komabe, mtengo wopangira ndi wokwera.Makona anayi amapangidwa kukhala ma trapezoid, ngodya ndi ngodya zakuthwa kuti apititse patsogolo kuphwanyidwa kwa chakudya chamafuta a forage, koma kukana kuvala ndikosavuta.Nyundo ya annular ili ndi dzenje limodzi lokha la pini, ndipo ngodya yogwira ntchito imasinthidwa panthawi yogwira ntchito, kotero kuvala kumakhala kofanana, moyo wautumiki ndi wautali, koma mapangidwe ake ndi ovuta.

Chitsulo chophatikizika cha makoswe nyundo ndi mbale yachitsulo yokhala ndi kuuma kwakukulu pazigawo ziwiri komanso kulimba kwabwino pakati, komwe kumaperekedwa ndi mphero.Ndizosavuta kupanga komanso zotsika mtengo.

Mayesowa amasonyeza kuti nyundo yokhala ndi kutalika koyenera ndi yopindulitsa kuwonjezera mphamvu ya ola la kilowatt, koma ngati ili yaitali kwambiri, kugwiritsa ntchito zitsulo kudzawonjezeka ndipo mphamvu ya ola ya kilowatt idzachepa.

Kuphatikiza apo, malinga ndi mayeso ophwanya chimanga opangidwa ndi China Academy of Agricultural Mechanisation ndi nyundo 1.6mm, 3.0mm, 5.0mm ndi 6.25mm, kuphwanya kwa nyundo za 1.6mm ndi 45% kuposa nyundo za 6.25mm, ndi 25.4 % apamwamba kuposa nyundo 5mm.

Nyundo yopyapyala imakhala ndi mphamvu yakuphwanya kwambiri, koma moyo wake wautumiki ndi waufupi.Kuchuluka kwa nyundo zomwe zimagwiritsidwa ntchito ziyenera kusiyana malinga ndi kukula kwa chinthu chophwanyidwa ndi chitsanzo.Nyundo ya chopukusira chakudya yakhazikitsidwa ku China.Unduna wa zamakina watsimikiza mitundu itatu ya nyundo zokhazikika (mtundu I, II ndi III) (nyundo zamabowo zamakona anayi).
