Description

Anordning ved gripebelter for traktorer. Device for grab belts for tractors.

Denne oppfinnelse vedrører en anordning ved gripebelter, særlig såkalte halv-belter for traktorer av den art som er lagt This invention relates to a device for grab belts, particularly so-called half-belts for tractors of the type laid down

om traktorens bakhjul og et foran dette about the tractor's rear wheel and one in front of it

bevegelig anordnet føringshjul, hvilke belter består av tverrgående gripebøyler som movable guide wheels, which belts consist of transverse grippers which

1 hver ende er stivt forbundet med festeledd 1 each end is rigidly connected with fastening joints

som er innbyrdes leddbart forbundet ved which are mutually articulated by

løkkeformede forbindelsesledd. Ved belter loop-shaped connectors. By belts

av denne art har gripebøylene en tendens of this nature the grip bars have a tendency

til å dreie eller «legge» seg slik at deres to turn or "lie down" so that their

effektive gripeevne reduseres, og dette er effective grip is reduced, and this is

særlig tilfelle ved bruk av i beltet innsatte especially the case when using in the belt inmates

spesielle bøyler eller snøribber, idet disse special hoops or snow ribs, as these

har noe større høyde enn vanlige gripe-bøyler og skal tjene til å øke beltets gripeevne på underlag av snø eller annet bløtt has a slightly higher height than normal grab bars and should serve to increase the belt's gripping ability on snow or other soft surfaces

materiale. material.

Formålet med foreliggende oppfinnelse The object of the present invention

er å bortskaffe ovennevnte ulempe og oppfinnelsen utmerker seg ved at der til hvert is to dispose of the above-mentioned disadvantage and the invention is distinguished by the fact that there to each

av de stive festeledd er festet to nabobøyler two neighboring braces are attached to the rigid attachment joints

med den fastsatte innbyrdes avstand, hvorved bøylene gjensidig støtter hverandre under ingrepet med underlaget, når de passerer under traktorens hjul. with the fixed mutual distance, whereby the hoops mutually support each other during the engagement with the ground, when they pass under the tractor's wheels.

Oppfinnelsen er illustrert på tegningen The invention is illustrated in the drawing

hvor fig. 1 viser et festeledd sett fra siden, where fig. 1 shows a fastening joint seen from the side,

og fig. 2 viser et stykke av et belte i per-spektivriss. and fig. 2 shows a piece of a belt in perspective view.

På tegningen betegner 1 et festeledd In the drawing, 1 denotes a fastening joint

som i hver ende er bøyet oppad i krokform which at each end is bent upwards in the shape of a hook

2 for påhukning av et løkkeformet ledd 3 2 for squatting a loop-shaped joint 3

som forbinder festeleddene med hverandre which connect the attachment joints to each other

innbyrdes. mutually.

I henhold til oppfinnelsen er festeleddene 1 dannet med en slik lengde at de tje-ner til befestigelse av to tverrgående gri-pebøyler 4 med den fastsatte innbyrdes avstand, idet bøylene blir liggende så nær inntil den tilliggende krok 2 at dennes åp-ning sperres slik at forbindelsesleddet 3 ikke kan føres ut av samme. According to the invention, the attachment links 1 are formed with such a length that they serve to attach two transverse grab bars 4 with the determined mutual distance, the bars being so close to the adjacent hook 2 that its opening is blocked so that the connecting link 3 cannot be led out of it.

I fig. 2 er vist en utførelse hvor vanlige gripebøyler 4 er festet parvis på feste-delene 1 som ovenfor beskrevet. Som vist i fig. 1 kan imidlertid den ene bøyle 4' i paret ha form av en spesialbøyle, eller så-kalt «snøribbe», med noe større høyde enn bøylen 4. In fig. 2 shows an embodiment where ordinary grippers 4 are attached in pairs to the attachment parts 1 as described above. As shown in fig. 1, however, one hoop 4' in the pair can have the form of a special hoop, or so-called "snow rib", with a somewhat greater height than hoop 4.

Ved den foran beskrevne konstruksjon får beltet større stabilitet i lengderetnin-gen uten at den nødvendige bøyelighet be-grenses, og-ved at bøylene er festet parvis på festeledd vil de under inngrepet med underlaget støtte hverandre innbyrdes .slik at de ikke vil kunne dreie seg enkeltvis, som tidligere var tilfelle, og derved «legge» seg slik at beltets gripeevne reduseres. With the construction described above, the belt gains greater stability in the longitudinal direction without limiting the necessary flexibility, and because the hoops are fixed in pairs on fastening joints, they will support each other during engagement with the substrate, so that they will not be able to turn individually, as was previously the case, thereby "laying down" so that the belt's grip is reduced.

Claims (2)

1. Anordning ved gripebelter, særlig for traktorer av den art, hvor tverrgående ut-ad buede gripebøyler ved hver ende er stivt forbundet med festeledd som er innbyrdes leddbart forbundet ved forbindelsesledd, karakterisert ved at der til hvert av de stive festeledd (1) er festet to nabobøyler (4) med den fastsatte innbyrdes avstand hvorved bøylene gjensidig støtter hverandre under inngrepet med underlaget når de passerer under traktorens hjul.1. Device for grab belts, especially for tractors of the kind where transversely outwardly curved grab bars are rigidly connected at each end with fastening links which are mutually articulately connected by connecting links, characterized in that there is to each of the rigid fastening links (1) attached two neighboring hoops (4) with the fixed mutual distance whereby the hoops mutually support each other during the engagement with the ground when they pass under the tractor's wheels. 2. Anordning ifølge påstand 1, karakterisert ved at av de to til hvert festeledd festede bøyler omfatter den ene en ekstra gripebøyle med noe større høyde enn den annen, for kjøring på sneunderlag eller lignende.2. Device according to claim 1, characterized in that of the two hoops attached to each attachment link, one comprises an additional grab hoop with a slightly higher height than the other, for driving on snow or the like.
