Description
Anordning ved grøftegraveploger.
Foreliggende oppfinnelse vedrører en anordning ved grøftegravploger, og formå-let med oppfinnelsen er å skaffe en særlig for graving av skogsgrøfter beregnet grøf-tegraveplog, som krever mindre trekkraft og som gir jevnere sider og bunn i den ferdige grøft enn hva tilfelle er ved tidli-gere grøftegraveploger.
De hittil anvendte typer av skogsgrøf-tegraveploger er blitt utviklet til forholds-vis store enheter. Den trekkmotstand som forekommer under grøftegravearbeidet krever store trekkmaskiner, såsom larve-traktorer. Ut fra anvendelses- og trans-portøkonomiske synspunkter bør trekk-maskinens størrelse holdes minst mulig, men dette krever igjen at plogens trekkmotstand bør kunne forminskes i motsva-rende grad. Man har forsøkt å forminske trekkmotstanden ved hjelp av forskjellige på plogen anordnede bunnkonstruks joner som glir langs grøftens bunn og samtidig også gjør grøftens sider fastere. På denne måte har man i noen grad kunnet forminske trekkmotstanden, men dog ikke tilstrek-kelig på grunn av den optredende glide-friksjon.
Hensikten med anordningen i henhold til oppfinnelsen er å oppnå en ytterligere forminskelse av trekkmotstanden, og anordningen i henhold til oppfinnelsen er hovedsakelig karakterisert ved at der i plogens bakre del mellom plogvingene er anordnet et bærehjul, hvis profil motsvarer profilet av den grøft som skal graves. Bærehjulet er hensiktsmessig innstillbart i vertikalretningen.
Oppfinnelsen er nærmere beskrevet i det følgende under henvisning til tegningen som viser et eksempel, på en anordning i henhold til oppfinnelsen anvendt på en skogsgrøftegraveplog.
På tegningen viser fig. 1 skogsgrøfte-graveplogen i sideriss.
Fig. 2 viser den samme plog sett bakf ra. På tegningen betegner 1 plogens rygg, på hvis fremre ende der er anordnet en roterende kniv 2 og en aksel som bærer to hjul 3. 4 betegner plogens vinger og 5 et plogskjær. Et bærehjul 6 er anordnet mellom vingene 4 og lagret i en ramme 7, som
er festet til vingene. Denne ramme er tre-delt med den mellomste del løftbar og senkbar for innstilling av bærehjulet 6
i egnet høyde. Bærehjulets profil motsvarer profilet av en ferdig grøft, idet hjulets
skrå sideplater 8 presser grøftens sider
faste og således hindrer løs jord i å renne ned i grøftens bunn.
Ved anvendelse av grøftegraveplogen i henhold til foreliggende oppfinnelse kan trekkmaskinene være betydelig mindre enn ved anvendelse av kjente grøftegraveplo-ger, da glidefriksjonen forminskes betydelig ved at den forvandles til rulle f riks jon samtidig som man oppnår en god grøft og ingen løs jord kan falle ned og stoppe til grøften.
Oppfinnelsen er naturligvis ikke be-grenset til det ovenfor beskrevne eksempel, men kan varieres på mange måter innen oppfinnelsens ramme. Således kan om øns-kelig bærehjulets profil modifiseres, og det
samme gjelder bærehjulets lagring.
