Ma backhoe loaders amadziwika kuti "otanganidwa kumapeto onse". Chifukwa chakuti ili ndi dongosolo lapadera, kutsogolo kutsogolo ndi chipangizo chotsitsa ndipo kumbuyo ndi chipangizo chofukula. Pamalo ogwirira ntchito, mutha kusintha kuchoka pa loader kupita ku excavator opareshoni ndikungotembenuza mpando. Ma backhoe loaders amagwiritsidwa ntchito kwambiri pomanga ndi kukonza misewu yayikulu yakumidzi ndi yakumidzi, kuyatsa zingwe, mphamvu zamagetsi ndi ntchito za eyapoti, zomangamanga zamatauni, zomangamanga zosungira madzi m'mafamu, zomanga nyumba zakumidzi, migodi ya miyala, ndi ntchito zosiyanasiyana zomanga zomwe timagulu tating'onoting'ono tosiyanasiyana tomanga. . "Mapeto awiri otanganidwa" ndi mtundu wa makina ang'onoang'ono opangira ntchito zambiri. Nthawi zambiri amagwiritsidwa ntchito m'mapulojekiti ang'onoang'ono akamaliza ntchito zazikulu.
1. Gulu la backhoe loaders
Ma backhoe loaders amadziwika kuti "otanganidwa kumapeto onse awiri" ndipo ali ndi ntchito ziwiri: kukweza ndi kukumba. Ma backhoe loaders amagawidwa motere:
1. Mwamapangidwe
Kuchokera pamawonedwe apangidwe, pali mitundu iwiri ya backhoe loaders: imodzi ndi chimango chosinthira mbali ndi ina yopanda chimango chosinthira mbali. Mbali yaikulu ya wakale ndi kuti pofukula ntchito chipangizo akhoza kusunthidwa m'mbali kuti atsogolere ntchito mu malo apadera. Pakatikati pa mphamvu yokoka ndi yotsika pamene ili mu kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka anthu. Zoyipa zake ndi izi: chifukwa cha kuchepa kwa kapangidwe kake, zotulukapo nthawi zambiri zimakhala zowongoka miyendo, mfundo zothandizira zili m'mphepete mwa gudumu, mtunda wapakati pazigawo ziwirizo ndizochepa, ndipo kukhazikika kwa makina onse kumakhala koyipa pakukumba (makamaka pamene chipangizo chogwirira ntchito chofukula chimasunthidwa mbali imodzi). Ntchito ya mtundu uwu wa backhoe loader imayang'ana pa kukweza, ndipo imapangidwa kwambiri ku Ulaya; chotsirizira chofukula ntchito chipangizo sangathe anasuntha cham'mbali, ndi lonse pofukula ntchito chipangizo akhoza atembenuza 180 ° kuzungulira pakati pa mbali ya kumbuyo kwa chimango kudzera thandizo slewing. Miyendo ndi zothandizira zamtundu wa chule, ndipo mfundo zothandizira zimatha kupita kunja ndi kumbuyo kwa gudumu, zomwe zimapereka bata labwino pokumba komanso zimathandiza kukulitsa luso lakukumba. Popeza palibe chimango chosinthira mbali, mtengo wa makina onse umachepetsedwa molingana. Choyipa chake ndi chakuti chidebecho chimapachikidwa kumbuyo kwa galimoto pamene chidebecho chimachotsedwa, ndipo miyeso yakunja ndi yaitali. Pamene locomotive ili mu kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake. Ntchito yachitsanzo ichi imayang'ana pakukumba ndipo amapangidwa ku United States. Kwambiri.
2. Kugawa mphamvu
Pankhani ya kugawa mphamvu, ma backhoe loaders amabwera m'njira ziwiri: magudumu awiri (kumbuyo) ndi magudumu anayi (onse). Zakale sizingagwiritse ntchito mokwanira kulemera kwake, kotero kumamatira pakati pa locomotive ndi pansi ndi mphamvu yokoka ndi yotsika kuposa yotsirizirayi, koma mtengo wake ndi wotsika kwambiri kuposa womaliza.
3. Pa chassis
Chassis: Pakati pa mitundu itatu ya chassis yomwe imagwiritsidwa ntchito pamakina ang'onoang'ono opangira ntchito zambiri, mphamvu ya zofukula zazing'ono zimakhala pansi pa 20kW, kuchuluka kwa makina onse ndi 1000-3000kg, ndipo imagwiritsa ntchito makina oyenda oyenda ndi liwiro locheperako. mpaka 5km/h. Amagwiritsidwa ntchito kwambiri m'minda ndi m'minda. ndi ntchito zina zazing'ono zoyendetsa nthaka. Chifukwa cha chitsanzo chake chaching'ono komanso mtengo wokwera mtengo, pakali pano ndizovuta kufalitsa ku China; mphamvu ya backhoe loader nthawi zambiri ndi 30-60kW, kulemera kwa makina ndi kwakukulu, kulemera kwake ndi pafupifupi 5000-8000kg, mphamvu yofukula imakhala yamphamvu, ndipo chonyamula magudumu chimagwiritsidwa ntchito kwambiri. Ili ndi makina oyenda, magudumu onse, ndipo imagwiritsa ntchito chowongolera chowongolera kapena chiwongolero chodziwika bwino. Liwiro lagalimoto ndilokwera kwambiri, limafikira kupitirira 20km/h. Amagwiritsidwa ntchito kwambiri kunja kwa ntchito zapadziko lapansi m'mafamu, zomangamanga, kukonza misewu ndi ntchito zina komanso ntchito zothandizira pa malo akuluakulu omanga. Chitsanzochi chimakhala ndi maonekedwe akuluakulu komanso osasinthasintha, ndipo nthawi zambiri zimakhala zovuta kuti zigwirizane ndi machitidwe ang'onoang'ono.
