Mutu Wopanga Nyundo
Chowonjezera cha makina a zaulimi ichi, chotchedwa hammer claw, ndi chinthu chachikulu chomwe chimawonongeka mosavuta pa makina ophwanyira ndi kubweza udzu. Chimapangidwa motsatira muyezo wa JB/T10813-2007, chimagwirizana ndi mitundu yosiyanasiyana ya makina a zaulimi, ndipo chimagwiritsidwa ntchito kwambiri pophwanyira ndi kubweza udzu wa mbewu monga chimanga, tirigu, ndi thonje. Chili ndi ntchito zitatu: kugwira, kukhudza, ndi kuphwanya, ndipo ndi chowonjezera chofunikira kwambiri pakukweza magwiridwe antchito a makina a zaulimi ndikuwonetsetsa kuti udzu wabweza udzu m'munda.
- Uwu ndi mutu wa pick wopangidwa ndi forged pick (mutu wa mattock) wopangidwa ndi chitsulo cha carbon champhamvu kwambiri pogwiritsa ntchito forging yotentha,
- yokhala ndi utoto wakuda woletsa dzimbiri kuti ikhale yolimba.
- Ili ndi m'mphepete mwake waukulu, wosalala ngati chisel wosweka zipangizo zolimba,
- thupi lapakati lolimba kuti litenge mphamvu yogwira,
- ndi soketi yozungulira pansi yoikira chogwirira (matabwa kapena fiberglass).
- Kapangidwe kake kamatsimikizira kulimba kwambiri komanso kukana kusweka pansi pa ntchito yolemetsa.
Kapangidwe kake kamapangitsa kuti zinthu zizigwira ntchito bwino komanso kuti zinthu zisamayende bwino. Mphepete yopanda kanthu pamwamba pa thupi la nyundo imachepetsa kulemera kwa chinthucho ndikusunga zinthu zopangira, pomwe imachepetsa kugwiritsa ntchito mphamvu zamagetsi ndikuwongolera ndalama zogwirira ntchito. Mphete ziwiri zomangira mbali zonse ziwiri zimathandiza kuti zikhale zosavuta kusonkhanitsa, kuonetsetsa kuti kulumikizana kuli kotetezeka, komanso kuyika bwino shaft yomangira, kuteteza kumasuka kapena kusakhazikika bwino panthawi yogwira ntchito ndikutsimikizira chitetezo cha ntchito.
Pamwamba pake pamakhala zokutira za chrome kuti zisawonongeke, ndipo nthawi yoyesera ya mchere imapitirira maola 480, zomwe zimaposa muyezo wa dziko lonse. Imatha kupirira bwino chilengedwe chonyowa komanso chowononga cha m'munda ndikuwonjezera moyo wake wogwirira ntchito. Kulondola kwa gawo la chinthucho kumayendetsedwa mkati mwa ±0.02mm, ndi kusinthasintha kwamphamvu, ndipo imagwirizana ndi mitundu yosiyanasiyana ya makina a ulimi. Palibe kusintha kwina komwe kumafunika, komwe kumachepetsa kwambiri ndalama zosamalira za wogwiritsa ntchito. Ndi gawo lothandizira lokondedwa pa ntchito zazikulu komanso zogwira mtima muulimi wamakono.
