Inotaridzwa semichina inorema yekuvaka, yekuchera, inozivikanwawo semuchina wekuchera, unozivikanwawo seanochera, Muchina unofamba nevhu unoshandisa bhaketi kuchera zvinhu pamusoro kana pazasi penzvimbo inotakura uye kuzviisa mumotokari yekutakura kana kuburitsa. kusvika kuchitokisi.

Zvinhu zvakacherwa nemucheri zvinonyanya ivhu, marasha, silt, ivhu uye dombo mushure mekutanga kusunungurwa. Tichitarisa kubva pakuvandudzwa kwemichina yekuvaka mumakore achangopfuura, kugadzirwa kwevacheri kunokurumidza kukurumidza, uye vanochera vave chimwe chezvinhu zvakakosha zvikuru. kuvaka michini mu engineering building.The matatu anokosha parameters of an excavator: kushanda uremu (misa), injini simba uye bhakiti kugona.

Yakakamurwa kuita yemukati yekupisa dhiraivha yekuchera uye yemagetsi dhiraivha yekuchera zvinoenderana nemaitiro ekutyaira, Zvinoenderana nenzira yekufamba, inogona kupatsanurwa kuva vanochera vanochera uye vanochera mavhiri.

Zvinoenderana neiyo nzira yekufambisa, inogona zvakare kukamurwa kuita ma hydraulic excavators uye mechanical excavator, Kana zvinoenderana nebhaketi, ine nzira mbiri: kumberi kwefoshoro kuchera, backhoe kuchera.

Huremu hwekushandisa ndechimwe chezvitatu zvakakosha maparamendi emucheri (simba reinjini, bhaketi simba, huremu hwekushanda), Huremu hwekushandisa hunotaridza mwero wemucheri uye unotaridza muganho wepamusoro wesimba rekuchera remucheri.

Simba rekuchera≦m;

Kushanda huremu m: adhesion coefficient pakati pevhu neanokambaira, Kana simba rekuchera rakapfuura muganhu uyu, kana iri backhoe, mucheri anotsvedza odhonzwa kumberi, izvo zvine njodzi.Mumamiriro ezvinhu efoshoro, mucheri anotsvedza achidzokera kumashure.Kuchera simba, kwesimba rekuchera, simba rekuchera rinonyanya kukamurwa kuva forearm yekuchera simba uye bhaketi rekuchera simba.

Zviito zvezviito zvemasimba maviri ekuchera ndiwo midzi yezino yebhakiti (muromo webhakiti), asi simba rakasiyana.Iyo forearm yekuchera simba inobva kune forearm cylinder;simba rekuchera bucket rinobva mubucket oil cylinder.

Kutsikirira kwakananga kwepasi, ukuru hwepasi chaihwo kudzvanyirira kunoratidza mamiriro epasi akakodzera kuti mucheri ashande.Kutsikirira kwepasi kunoreva kudzvanywa kunoitwa nehuremu hwemuchina uri pasi, unoratidzwa nenzira inotevera: = kushanda uremu ÷ nzvimbo yese yakabatana nevhu,Track shangu, zvakakosha kuisa bhutsu dzakakodzera pamushini.Kune vanochera vanochera, maitiro ekusarudza anokambaira ndeokuti: Pese pazvinogoneka, edza kushandisa shangu dzakatetepa.

Common track types: toothed track shoes, flat track shoes, flat track shoes,Kufamba kumhanya, kune vanochera vanochera, nguva yekufamba inotora chikamu chimwe mugumi chenguva yese yekushanda.

Kazhinji, mamhanyiro maviri anogona kusangana nekufamba kwemucheri.Simba rekufambisa, simba rekufambisa rinoreva simba rinogadzirwa nemucheri kana achifamba, izvo zvinonyanya kuenderana nemotokari yekufambisa yemucheri.Izvi zviviri zvekufamba kwekuita parameters zvinoratidza kufamba. chemucheri uye kugona kwayo kufamba.Inogona kuratidzirwa mumasampuli evagadziri vakasiyana-siyana.

Kukwanisa kukwira, kudzika, kana kumira panzvimbo yakadzikama, yakatsetseka.Nzira mbiri dzekumiririra: angle, percentage,Lifting capacity, lifting capacity zvinoreva idiki yeyakatemerwa yakatsiga kusimudza simba kana rated hydraulic lifting capacity. .Rated yakagadzikana kusimudza simba: 75% yetipping load, yakatarwa hydraulic lift capacity: 87% ye hydraulic lift capacity

Speed ​​yekuswing inoreva avhareji yekumhanya iyo mucheri anogona kuwana panguva yakagadzikana kana mucherechedzo waburutswa.Izvi zvinoreva kuti spidhi inotsanangurwa inouraya, kwete painotangira, kana pakubhureki;Kureva kuti, kwete slew speed yekumhanyisa kana kuderera. .Pabasa rekuchera zvakazara, Kana mucheri uyu uchishanda pakati pe0 ° kusvika 180 °, mota inouraya inomhanyisa kana kudzikira, uye kana yatendeuka kusvika ku270 ° kusvika 360 °, kumhanya kwekuuraya kunobva kwagadzikana. basa rekuchera, kumhanya kwekutenderera kunotsanangurwa pamusoro apa hakugoneki.

Kureva kuti, inodiwa chaiyo yekuzunguza kuita ndeyekumhanyisa/kuderera kunoratidzwa maererano nekuzunguza torque.Engine simba, gross horsepower inoreva simba rinobuda rakayerwa painjini flywheel pasina zvinhu zvinopedza simba zvakadai semamufflers, mafeni, alternator uye mafirita emhepo. Simba rinoshanda (net horsepower) rinoreva simba rinobuda rakayerwa painjini flywheel ine zvese zvinodya simba zvakaita semamufflers, mafeni, maalternator nemafirita emhepo akaiswa.

Kuyera kweruzha, ruzha rwekuchera kazhinji runobva muinjini.Mhando mbiri dzeruzha: kuyerwa kweruzha panzeve yemushandisi, kuyerwa kweruzha kwakatenderedza muchina
