KUGWIRITSA NTCHITO NDI MAINTENANCE ya BRUSHCUTTER

1: Mapulogalamu ndi magulu

Chodulira tchire ndichoyenera kwambiri kumeta pa nthaka yosakhazikika komanso yosafanana ndi udzu wakuthengo, zitsamba ndi udzu wochita kupanga m'mphepete mwa misewu ya nkhalango.Udzu wodulidwa ndi brushcutter siwophwanyidwa kwambiri, ndipo malowa amakhala osokonezeka pang'ono atachitidwa opaleshoni, koma opepuka, osavuta kunyamula komanso osinthika kumadera apadera amakhala ndi gawo lomwe okonza udzu ena sangasinthe.

Magulu a maburashi: Mitundu ya maburashi amatha kugawidwa m'manja, okwera m'mbali ndi m'chikwama molingana ndi momwe amanyamulira.Malinga ndi mtundu wa shaft yapakatikati, imatha kugawidwa kukhala yolimba shaft drive ndi shaft drive yofewa.Malinga ndi magwero osiyanasiyana amagetsi, amagawidwa kukhala mtundu wa injini ya petulo ndi mtundu wamagetsi, womwe mtundu wamagetsi umakhala ndi mtundu wa batire ndi mtundu wa AC.

Kapangidwe ka ntchito ndi mfundo yogwirira ntchito ya brushcutter: maburashi nthawi zambiri amakhala ndi injini, makina otumizira, magawo ogwirira ntchito, makina ogwiritsira ntchito ndi makina opachika kumbuyo.

Injini nthawi zambiri imakhala ndi injini imodzi ya silinda imodzi yokhala ndi mpweya woziziritsidwa ndi mpweya wokhala ndi mphamvu ya 0.74-2.21 kilowatts.Njira yotumizira imatumiza mphamvu ya injini kumalo ogwirira ntchito, kuphatikizapo clutch, shaft transmission yapakatikati, reducer, etc. Clutch ndi gawo lofunika kwambiri lamagetsi, lomwe makamaka limapangidwa ndi centrifugal chipika, mpando wa centrifugal block, masika ndi clutch. diski.

Kuyambira injini, pamene liwiro la injini lifika 2600-3400 rpm, pansi pa mphamvu ya centrifugal, chipika cha centrifugal chimagonjetsa preload ya kasupe ndikutsegula kunja, ndipo chimbale chowawa chimaphatikizidwa ndi chimodzi chifukwa cha mikangano, ndipo clutch imayamba. kugwira ntchito ndi kutumiza torque.Pamene liwiro la injini likuwonjezeka, clutch imatumiza torque pazipita ndi mphamvu pazipita injini.Makokedwe omwe amafalitsidwa ndi clutch amaperekedwa kwa chochepetsera kudzera mumtsinje wotumizira, ndipo chochepetsera chimachepetsa liwiro la injini pafupifupi 7000 rpm kupita ku liwiro logwira ntchito, ndipo magawo ogwira ntchito amadulidwa.

Pamene liwiro la injini ndi zosakwana 2600 rpm, chifukwa cha kufooka kwa mphamvu ya centrifugal, kasupe amabwezeretsedwa, kotero kuti chipika cha centrifugal chimasiyanitsidwa ndi centrifugal disc, ndipo clutch imasiya kugwira ntchito ndipo sichimatumizanso torque.Liwiro la injini pamene cholumikizira chikuphatikizidwa chimatchedwa liwiro la meshing.Liwiro la injini liyenera kukhala lalikulu kuposa liwiro la ma meshing pogwira ntchito.

Mbali zogwirira ntchito za burashi ndi kudula mitu, makamaka kuphatikiza masamba odulira, masamba opindika ndi mipeni yodulira zingwe za nayiloni.Tsamba lofunikira lili ndi mano 2, mano 3, mano 4, mano 8, mano 40 ndi mano 80.Tsamba lopindika limakhala ndi mutu wodula, tsamba, mphete yotsutsa-roll ndi tray yapansi.Tsambali liri ndi masamba atatu, oyikidwa mofanana pamutu wodula, tsamba lililonse limakhala ndi m'mphepete mwake, ndipo limatha kusinthidwa ku U-turn.Pakatikati mwa tsamba pali poyambira wautali kuti musinthe kufalikira kwa tsamba kunja kwa mutu wodula.Tsamba likhoza kukulitsidwa podula udzu waung'ono, ndipo kudula kwa namsongole wakale kuyenera kufupikitsidwa.Mukakwera, kutalika kwa tsamba kuyenera kukhala kofanana.Mutu wa nayiloni wotchera zingwe umapangidwa ndi chipolopolo, chingwe cha nayiloni, chingwe cha chingwe, shaft, batani, ndi zina.

Brushcutter ndi mthandizi wabwino pakumalizitsa dimba, wokhala ndi kukula kochepa, kulemera kwake, komanso wamphamvu, ndipo ndi chida chamunda chomwe chimakondedwa ndi ogwira ntchito m'munda.Kuti burashi ikhale yogwira ntchito bwino komanso kuti ipereke kusewera kwathunthu pazabwino zake zonse, ndikofunikira kusintha chodulacho.Kusintha kwa brushcutter makamaka kumakhala ndi zosintha zisanu ndi zitatu izi:
