Martin Engineering yalengeza makina awiri olimba otsukira lamba, omwe adapangidwa kuti azigwira ntchito mwachangu komanso mosavuta.
Ma DT2S ndi DT2H Reversible Cleaners apangidwa kuti achepetse nthawi yogwira ntchito ndi ntchito yoyeretsa kapena kukonza, pomwe akuthandiza kukulitsa moyo wa makina ena.zigawo zonyamulira.
Pokhala ndi katiriji yapadera yogawanika yomwe imalowa ndi kutuluka pa mandrel yachitsulo chosapanga dzimbiri, chotsukiracho chikhoza kukonzedwa kapena kusinthidwa popanda kuyimitsa chonyamuliracho pamene zilolezo zachitetezo chamunda zili pamalo ake. "Ngakhale chotsukiracho chitakhala chodzaza ndi zinthu," adatero Dave Mueller, Woyang'anira Zogulitsa za Conveyor ku Martin Engineering, "theka la chimango chogawanikacho likhoza kuchotsedwa kotero chinthu chosefera chikhoza kusinthidwa mumphindi zisanu. Izi zimathandiza wogwiritsa ntchito kukhala ndi makatiriji ena owonjezera ndikusintha masamba mwachangu akafunika kusinthidwa. Kenako amatha kubweza makatiriji ogwiritsidwa ntchito ku sitolo, kuwayeretsa ndikusintha masamba kuti akhale okonzeka ntchito yotsatira."
Zotsukira zachiwirizi ndizoyenera kugwiritsidwa ntchito m'njira zosiyanasiyana, kuyambira migodi, kukonza zipangizo ndi kukumba miyala mpaka kupanga simenti, kukonza chakudya ndi ntchito zina zosamalira zinthu zambiri. Zonsezi zimachepetsa kwambiri kunyamula zinthu, ndipo zimapangidwa kuti zigwirizane ndi zotengera zobwerera m'mbuyo kuti zisawononge malamba kapena ma splices. Chotsukira cha DT2 chokhala ndi tsamba lachitsulo ndi nsonga ya tungsten carbide m'munsi wosinthasintha, chimapereka yankho losavuta komanso lothandiza pamavuto ambiri okhudzana ndi backhaul.
DT2H Reversible Cleaner XHD yapangidwa kuti igwiritsidwe ntchito pamavuto ovuta kwambiri, yokhala ndi katundu wolemera pa malamba okhala ndi mainchesi 400 mpaka 2400 mm m'lifupi ndipo imagwira ntchito pa liwiro lofika 1200 ft/min (6.1 m/s). Kumanga kwa carryback kungachitike pobwerera kwa conveyor pamene makina oyeretsera pa conveyor alephera kuchotsa zinthu zambiri zomwe zimamatira ku conveyor lamba atatulutsa katunduyo. Kuwonjezeka kwa kuchuluka kwa carry kumapangitsa kuti ntchito yoyeretsa isagwire ntchito mosayenera, ndipo ngati sikulamulidwa, kungayambitse kulephera msanga kwa zigawo za conveyor.
“Kunyamula katundu wobwerera m’mbuyo kumatha kukhala ndi kapangidwe komata kwambiri komanso kolimba, komwe kungaipitse zigawo za conveyor ndikuyambitsa kulephera msanga,” akutero Mueller. “Chinsinsi cha kupambana kwa otsuka awa ndi ngodya yoyipa ya rake (yochepera 90°) ya masamba. Ndi ngodya yoyipa, mumapeza 'kukanda' komwe kumachepetsa kuwonongeka kwa lamba pomwe kumapereka ntchito yabwino kwambiri yoyeretsa,” akutero.
Monga m'bale wake wamkulu, Martin DT2S Reversing Cleaner ikhoza kuyikidwa pa malamba okhala ndi mainchesi 18 mpaka 96 (400 mpaka 4800 mm) m'lifupi. Komabe, mosiyana ndi DT2H, DT2S idapangidwa kuti ifikire liwiro lotsika la lamba la 900 fpm (4.6 m/sec) pa malamba okhala ndi ma splices okhuthala. Mueller akunena kuti izi zimachitika makamaka chifukwa cha kusiyana kwa momwe amagwiritsidwira ntchito: "DT2S ili ndi chimango chopyapyala chomwe chimathandiza kuti igwirizane m'malo opapatiza ngati mainchesi 7 (178 mm). Chifukwa chake, DT2S ikhoza kumangiriridwa ku lamba laling'ono kwambiri."
Zotsukira zonse za DT2 zitha kugwiritsidwa ntchito m'malo ogwirira ntchito apakatikati mpaka olemera, kupereka mayankho olimba ku mavuto ovuta omwe amabwera chifukwa cha kubweza zinthu ndikuchepetsa zinthu zomwe zimatuluka.
Chitsanzo cha ntchito yoyera chingapezeke ku mgodi wa Pueblo Viejo Dominicana Corporation (PVDC) m'chigawo cha Sanchez Ramirez, pafupifupi makilomita 89 kumpoto chakumadzulo kwa Santo Domingo, Dominican Republic.
Ogwira ntchito amakumana ndi kunyamula katundu wambiri komanso fumbi pamakina awo onyamulira katundu, zomwe zimapangitsa kuti zida zawo ziwonongeke kwambiri, nthawi yosakonzekera yogwira ntchito komanso kukonza bwino. Kupanga kumachitika masiku 365 pachaka, koma pakati pa Epulo ndi Okutobala, chinyezi chimapangitsa kuti tinthu tating'onoting'ono ta dongo tisungunuke, zomwe zimapangitsa kuti katunduyo azimata. Chinthuchi, chomwe chimakhala ngati mankhwala otsukira mano okhuthala, chimathanso kumamatira zinthu zazing'ono ku lamba, zomwe zimapangitsa kuti katunduyo awonongeke zomwe zingawononge ma pulley ndi ma header.
M'masabata awiri okha, akatswiri a zomangamanga a Martin adasintha zotsukira lamba zomwe zinalipo kale m'malo 16 ndi zotsukira zoyambirira za Martin QC1 Cleaner XHD zokhala ndi masamba a urethane osamatirira kwambiri omwe adapangidwira zinthu zomata, Ndipo zotsukira zachiwiri za DT2H. Masamba otsukira achiwiri amatha kupirira kutentha kotentha kwa chilimwe, chinyezi chambiri komanso nthawi yopangira nthawi zonse.
Pambuyo pa kukonzedwanso, ntchito tsopano ndi zoyera, zotetezeka komanso zogwira ntchito bwino, zomwe zimapatsa akuluakulu ndi omwe akukhudzidwa chidaliro chachikulu pa ntchito yopitilira ya mgodi, yomwe ikuyembekezeka kukhala yopindulitsa kwa zaka 25 zikubwerazi kapena kuposerapo.
