Description

For stokker bestemt transportanordning som kobles til et trekkjøretøy. A transport device intended for sticks which is connected to a towing vehicle.

Denne oppfinnelse angår en for stokker This invention relates to one for canes

eller lignende bestemt transportanordning or similar specific transport device

som kobles til et trekkjøretøy, såsom en which connects to a towing vehicle, such as a

traktor, bestående av en med kjøretøyet tractor, consisting of one with the vehicle

leddforbundet, bakutrettet støttearm; organene for fastgjøring av lasset består av articulated, rear-facing support arm; the bodies for securing the load consist of

en stokkbenk og en bakenfor denne anordnet sperrekjetting. a cane bench and a back for this arranged locking chain.

Ved de hittil anvendte transportanord-ninger til dette formål er stokkbenken som In the case of the transport devices used up to now for this purpose, the cane bench which

bærer stokklasset, festet til en anordning carries the cane class, attached to a device

som kobles til endene av traktorens løfte-armer ved hjelp av en såkalt trepunktkob-ling. Anordningen består f. eks. av en vinkelformet vektarm, til hvis bakut rettede which is connected to the ends of the tractor's lifting arms by means of a so-called three-point coupling. The device consists, for example, of of an angular weight arm, to whose rearward direction

således en uheldig virkning på trekkjøre-tøyets, som traktorens styreevne, idet den thus an adverse effect on the steering ability of the towing vehicle, such as the tractor, as it

Da lassets virkepunkt ligger langt bak As the point of action of the load is far behind

traktorens bakhjul, nedsettes også traktorens trekke vne. the tractor's rear wheel, the tractor's pulling power is also reduced.

Formålet med oppfinnelsen er å skaf-fe en sådan transportanordning som er The purpose of the invention is to provide such a transport device which is

uten de nevnte ulemper, hvilket oppnås without the aforementioned disadvantages, which is achieved

ved hjelp av en meget pålitelig og sikker using a very reliable and secure

og med hensyn til konstruksjon enkel anordning. Oppfinnelsen utmerker seg først and with regard to construction simple device. The invention excels at first

og fremst ved en med støttearmens bakre and primarily by one with the rear of the support arm

ende leddforbundet, i det langsgående vertikalplan svingbar svingearm som i kjøre-retningen sett er rettet i hovedsaken skrått end jointed, in the longitudinal vertical plane pivotable swing arm which, seen in the direction of travel, is mainly directed obliquely

oppad, samt en mellom svingarmens fremre ende og støttearmens fremre ende, hensiktsmessig inntil det førstnevnte leddpunkt leddbart forbundet stiv, men med hensyn til sin lengde innstillbar påvirkningsarm, hvilken svingarm er forsynt med organer som er anbragt i kjøreretnin-gen i innbyrdes avstand og tjener til å fik-sere stokklasset til svingarmen på en sådan måte at lasset blir stivt forbundet med svingarmen når dennes øvre ende ved hjelp av påvirkningsarmen for løfting av lasset svinges om sitt leddpunkt på støttearmen. upwards, as well as an impact arm between the front end of the swing arm and the front end of the support arm, conveniently connected to the first-mentioned joint point in an articulated manner, but with respect to its length adjustable influence arm, which swing arm is provided with organs that are arranged in the direction of travel at a distance from each other and serve to to fix the cane beam to the swing arm in such a way that the load is rigidly connected to the swing arm when its upper end is swung about its joint point on the support arm by means of the influence arm for lifting the load.

Påvirkningsarmen i henhold til oppfinnelsen er hensiktsmessig av en hydraulisk påvirkbar arbeidssylinder med i denne forskyvbart stempel og stempelstang, idet den mot kjøretøyet rettede ende av påvirkningsarmen er svingbart festet i nærheten av den ende av støttearmen som er forbundet med kjøretøyet. Svingarmen er mellom sine leddpunkter fortrinnsvis ut-formet som en vinkelarm, hvis bakover rettede del som strekker seg i hovedsaken vannrett, bærer lassets festeorganer. Stokkbenken og kjettingen er festet til denne del. The influence arm according to the invention is suitably a hydraulically actuable working cylinder with a displaceable piston and piston rod therein, the end of the influence arm directed towards the vehicle being pivotably fixed near the end of the support arm which is connected to the vehicle. Between its joint points, the swing arm is preferably designed as an angle arm, whose rearward-directed part, which extends mainly horizontally, carries the load's fastening means. The cane bench and the chain are attached to this part.

Disse og andre trekk ved oppfinnelsen fremgår av følgende beskrivelse under hen-visning til tegningen som viser en anordning ifølge oppfinnelsen sett fra siden med heltrukne linjer i lastestillingen og med strekede linjer i transportstillingen. These and other features of the invention appear from the following description with reference to the drawing which shows a device according to the invention seen from the side with solid lines in the loading position and with dashed lines in the transport position.

På tegningen angir 1 en støttearm som ved hjelp av et universal- eller kryssledd 2 er således forbundet med f. eks. en traktor eller et annet trekkjøretøy at den kan svin- In the drawing, 1 indicates a support arm which, by means of a universal or cross joint 2, is thus connected to e.g. a tractor or other towing vehicle that it can

Svingarmen 4 er vinkelformet således The swing arm 4 is angularly shaped thus

at dens bakre del ligger i hovedsaken vannrett, og ved denne del er der festet en på tvers liggende stokkbenk 9. Svingarmen 4 er forlenget bakover forbi leddpunktet 3, that its rear part is mainly horizontal, and to this part a cross-lying cane bench 9 is attached. The swing arm 4 is extended backwards past the joint point 3,

Anordningen virker på følgende måte. The device works in the following way.

Når transportanordningen ligger senket When the transport device is lowered

ned på marken (vist med heltrukne linjer på tegningen), lesses stokkene således at deres fremre ender er fortannet for å øke grepet, hvorpå kjettingen 10 legges rundt stokkene og festes til tverrbjelken 11 ved hjelp av egnede anordninger. down on the ground (shown by solid lines in the drawing), the sticks are loaded so that their front ends are serrated to increase grip, after which the chain 10 is placed around the sticks and attached to the crossbeam 11 by means of suitable devices.
