Description

Anordning til sidestyring av redskap som er koplet til en traktor. Device for lateral steering of implements connected to a tractor.

Foreliggende oppfinnelse angår en anordning til sidestyring av redskap som er The present invention relates to a device for lateral control of implements which are

koplet til en traktor, ved sideforskyvning coupled to a tractor, by side shift

av de trekkstenger som forbinder traktor of the tie rods that connect the tractor

og redskap. and utensils.

Det er kjent slike styreanordninger som There are known such control devices as

går ut på at trekkstengene er forbundet presupposes that the tie rods are connected

over trinser eller hjul med et ratt eller liknende ved hjelp av kjettinger, slik at en over pulleys or wheels with a steering wheel or the like by means of chains, so that a

dreining av rattet bevirker forkorting av turning the steering wheel shortens the

kjettingen på den ene side og forlengning the chain on one side and extension

på den andre, slik at man på denne måte on the other, so that in this way

kan styre redskapet som trekkes etter can control the tool being pulled

traktoren. the tractor.

Hensikten med foreliggende oppfinnelse er å skaffe en særlig enkel slik styre-innretning, som kan monteres på en hvil-ken som helst traktor med små omkost-ninger. The purpose of the present invention is to provide a particularly simple such control device, which can be mounted on any tractor at low cost.

Ifølge oppfinnelsen anbringes det på According to the invention, it is placed on

traktoren fast anordnet et svingbart ledd the tractor is fixed with a swivel joint

som er forbundet med den ene av trekkstengene ved hjelp av et stivt stag, og videre er forbundet med en med sveiv eller which is connected to one of the tie rods by means of a rigid strut, and is further connected to one with a crank or

ratt utstyrt skrue ved hvis hjelp leddet steering wheel equipped screw with the help of which the joint

kan svinges om sin aksel. can be rotated about its axis.

Oppfinnelsen vil i det følgende bli be-skrevet under henvisning til et utførelses-eksempel som er vist på tegningen, hvor In the following, the invention will be described with reference to an embodiment shown in the drawing, where

fig. 1 viser et sideoppriss av en traktor med det ene hjul fjernet og fig. 1 shows a side elevation of a tractor with one wheel removed and

fig. 2 viser en del av traktoren fig. 2 shows part of the tractor

sett ovenfra. seen from above.

Traktoren 1 er forsynt med et svingbart ledd 2 som kan svinges om en bolt The tractor 1 is equipped with a pivotable joint 2 which can be pivoted about a bolt

eller liknende 3. Dette svingbare ledd er or similar 3. This swivel joint is

ved hjelp av et stivt stag 4 forbundet med by means of a rigid strut 4 connected with

en av trekkstengene 5 hvortil et redskap one of the drawbars 5 to which a tool

(ikke vist) er festet. Trekkstengene 5 er (not shown) is attached. The tie rods 5 are

på vanlig måte festet til ledd 6 som kan in the usual way attached to section 6 which can

betjenes ved hjelp av traktorens hydrau-liske løfteanordning. Til traktoren er videre festet et element 7 som tjener til å operated using the tractor's hydraulic lifting device. An element 7 is also attached to the tractor which serves to

holde en skrue forsynt med en sveiv 8, idet hold a screw provided with a crank 8, ie

denne skrue holdes av de to stag 9 og 10. this screw is held by the two struts 9 and 10.

Skruen er videre forbundet med et om bolten 11 svingbart ledd 12. Ved å dreie på The screw is further connected to a joint 12 which can be pivoted around the bolt 11. By turning on

rattet 8 vil skruen 13 ved hjelp av hylsen the steering wheel 8 will the screw 13 by means of the sleeve

14 som ved et ledd 15 er forbundet med 14 which is connected by a joint 15 with

elementet 12 forkortes eller forlenges, slik element 12 is shortened or lengthened, like this

at elementet 12 vil dreies i den ene eller that the element 12 will be rotated in the one or

annen retning om bolten 11. Denne dreining vil samtidig bevirke en svingning av other direction about the bolt 11. This turning will at the same time cause a swing of

elementet 2 som ved hjelp av staget 4 tar the element 2 which with the help of the rod 4 takes

med seg trekkstengene 5, slik at det til-koplede redskap styres dit man ønsker. with the drawbars 5, so that the connected implement is steered where you want.

Skruen 13 er på vanlig måte lagret opp The screw 13 is stored in the usual way

fritt dreibart i en hylse 16 og er låst ved freely rotatable in a sleeve 16 and is locked by

hjelp av to skiver 17 og 18. using two discs 17 and 18.
