Paub Txog Woodchipper
Feb 13, 2023
A ntoo chipperlos yogwoodchipper yog ib lub tshuab siv los txo cov ntoo (feem ntau cov ceg ntoo lossis pob tw) rau hauv cov ntoo me me. Lawv feem ntau nqa tau yooj yim, raug ntsia rau ntawm lub log ntawm cov thav ntawv tsim nyog rau kev thauj mus los tom qab lub tsheb lossis van. Lub zog feem ntau yog muab los ntawm lub tshuab hluav taws xob sab hauv los ntawm 2 txog 700 kilowatts (3 txog 1,000 horsepower). Kuj tseem muaj lub zog siab chipper qauv mounted rau cov tsheb thauj khoom thiab siv los ntawm lub cav sib cais. Cov qauv no feem ntau kuj muaj hydraulic winch.
Ntoo chippers feem ntau yog ua los ntawm hopper nrog dab tshos, lub tshuab chipper nws tus kheej, thiab ib qho kev xaiv sau rau hauv cov chips. Ib tsob ntoo limb yog muab tso rau hauv lub hopper (lub dab tshos ua ib feem kev ruaj ntseg mechanism kom tib neeg lub cev qhov chaw nyob deb ntawm lub chipping hniav) thiab pib mus rau hauv lub chipping mechanism. Cov chips tawm los ntawm ib lub chute thiab tuaj yeem raug coj mus rau hauv lub thawv tsheb thauj khoom lossis mus rau hauv av. Cov txiaj ntsig zoo yog chips ntawm qhov kev txiav txim ntawm 2.5-5 cm (1-2 nyob rau hauv) thoob plaws hauv qhov loj. Cov ntoo chips uas tau tshwm sim muaj ntau yam kev siv xws li kis tau los ua lub hau npog los yog muab tso rau hauv lub tshuab nqus tsev thaum lub sij hawm ua ntawv.
Feem ntau woodchippers cia siab rau lub zog khaws cia hauv lub flywheel hnyav los ua lawv txoj haujlwm (txawm tias qee qhov siv nruas). Cov hniav chipping yog ntsia rau ntawm lub ntsej muag ntawm lub flywheel, thiab lub flywheel yog nrawm los ntawm lub tshuab hluav taws xob lossis lub tshuab hluav taws xob sab hauv.
Cov ntoo loj loj tau nquag nruab nrog cov grooved rollers hauv caj pas ntawm lawv cov funnels pub. Thaum ib ceg tau tuav los ntawm cov chais, cov chais thauj cov ceg mus rau cov hniav ntawm qhov chaw ruaj khov. Cov rollers no yog ib qho kev nyab xeeb thiab feem ntau thim rov qab rau cov xwm txheej uas ib ceg raug ntes ntawm cov khaub ncaws.
Keeb kwm:
Woodchipper tau tsim los ntawm Peter Jensen (Maasbüll, Lub Tebchaws Yelemees) hauv xyoo 1884, "Marke Angeln" sai sai tau los ua cov lag luam tseem ceeb ntawm nws lub tuam txhab, uas twb tau tsim thiab kho kev sib koom tes- thiab woodworking-machinery.
Hom:
Disc
Fulghum Industries 240 cm (96 nyob rau hauv) -10K CCW Chipper
Tus thawj chipper tsim ntiav ib tug steel disk nrog cov hniav mounted rau nws raws li lub chipping mechanism. Cov thev naus laus zis no tau rov qab mus rau qhov tsim los ntawm German Heinrich Wigger, uas nws tau txais patent hauv xyoo 1922. Hauv qhov tsim no, (feem ntau) thim rov qab hydraulically powered log rub cov khoom los ntawm lub hopper ntawm lub disk, uas yog mounted perpendicularly rau cov khoom tuaj. Raws li lub disk yog tig los ntawm lub cev muaj zog, cov hniav mounted rau ntawm lub ntsej muag ntawm lub disk txiav cov khoom mus rau hauv chips. Cov no yog pov tawm lub chute los ntawm flanges ntawm cov npoo ntawm lub disk.
Kev lag luam-qib disk-style chippers feem ntau muaj cov khoom siv txoj kab uas hla ntawm 15 txog 45 cm (6 txog 18 nyob rau hauv). Industrial-qib chippers (tub grinders) muaj nrog cov discs loj li 4 m (160 in) inch, xav tau 3,{10}} txog 3,700 kW (4,{14}} txog 5,{{16} } hp). Ib daim ntawv thov kev lag luam disk chippers yog los tsim cov ntoo chips siv hauv kev tsim khoom ntawm particle board.
Nruas
Niaj hnub nimno-style nruas chipper "Bandit Industries Model 1290H"
Nruas chippers ntiav cov cuab yeej uas muaj lub nruas hlau loj uas siv los ntawm lub cev muaj zog. Lub nruas yog mounted parallel rau lub hopper thiab tig mus rau lub chute. Hniav mounted rau sab nrauv ntawm lub nruas txiav cov khoom rau hauv chips thiab txav cov chips mus rau hauv qhov tso tawm chute. Kev lag luam-qib nruas-style chippers feem ntau muaj cov khoom siv txoj kab uas hla ntawm 25 txog 60 cm (9 mus rau 24 hauv).
Conventionally-fed nruas chippers siv lub nruas raws li pub mechanism, kos cov khoom los ntawm nws chips nws. Cov no yog cov npe hu ua "chuck-and-duck" chippers, vim qhov nrawm nrawm los ntawm cov khoom poob rau hauv lub nruas. Chippers ntawm hom no muaj ntau qhov tsis zoo thiab teeb meem kev nyab xeeb. Yog hais tias tus neeg teb xov tooj tau snagged ntawm cov khoom noj rau hauv lub tshuab, kev raug mob los yog kev tuag yog heev. Hydraulic-fed nruas chippers tau hloov pauv cov tshuab ua pa. Cov chippers no siv cov txheej txheem hydraulically powered log los tswj tus nqi ntawm cov khoom noj rau hauv lub nruas chipper.
Lwm yam:
Muaj ntau lub tshuab loj rau kev ua ntoo. "Txhua tsob ntoo chippers" thiab "Recyclers", uas feem ntau tuaj yeem tswj cov khoom siv qhov ntev ntawm 60-180 cm (2-6 ft) tuaj yeem siv nruas, disks, lossis ob qho tib si ua ke. Cov tshuab loj tshaj plaws siv hauv kev ua ntoo, feem ntau hu ua "Tub lossis Kab rov tav Grinders", tuaj yeem tuav cov khoom siv txoj kab uas hla ntawm 2.4 m (8 ft) lossis ntau dua, thiab siv cov carbide tipped flail hammers rau pulverize ntoo es tsis txiav nws, ua cov ntoo shredded. tsis yog chip los yog chunk. Cov tshuab no feem ntau muaj lub zog ntawm 150–750 kW (200–1,{11}} hp). Feem ntau hnyav heev uas lawv xav tau ib lub tsheb thauj khoom semi-trailer thauj. Cov qauv me me tuaj yeem rub los ntawm lub tsheb thauj khoom nruab nrab.
Cov hniav:
Txawm hais tias chippers txawv heev hauv qhov loj, hom, thiab muaj peev xwm, cov hniav ua cov ntoo zoo sib xws hauv kev tsim kho. Lawv yog cov duab plaub thiab feem ntau yog 4-10 cm (1 ntxiv rau 1⁄2–4 hauv) hla los ntawm 15–30 cm (6–12 hauv) ntev. Lawv txawv nyob rau hauv thickness ntawm li 4-5 cm (1 ntxiv 1⁄2-2 nyob rau hauv). Chipper hniav yog tsim los ntawm qib siab steel thiab feem ntau muaj tsawg kawg yog 8 feem pua chromium rau hardness.
Cov kev pabcuam hauv nroog:
Cov ceg ntoo poob, tshwj xeeb tshaj yog thaum nws xav tias lawv raug kab los ntawm kab los yog lawv cov larva, yogchippedtiv thaiv kab mob ntxiv. Lub nroog tsoomfwv tau txais thiab ua haujlwm chippers raws li xav tau, suav nrog rau kev siv raws caij nyoog.
Kev nyab xeeb:
Peb caug-ib tus neeg raug tua nyob rau hauv woodchipper xwm txheej ntawm 1992 thiab 2002 hauv Teb Chaws Asmeskas, raws li tsab ntawv tshaj tawm xyoo 2005 los ntawmPhau ntawv Journal ntawm American Medical Association.
