Abstract

Apparatus for eliminating the problems posed by the use of agricultural tools which are hitched via the three-point system, on sloping ground. It is made up of a crossmember (2) and two arms (I) adjustable in terms of width (II), to which are fixed the hitching arms (lower links) of the tractor (9) and the third point (top link) (7). The agricultural tool is fixed at the top to a ball joint which is articulated and adjustable in terms of length (3), and at the bottom to two clevises (yokes) with ball joints (4) mounted on slideways (5) and the length of which can be varied via two hydraulic cylinders (6). This device is particularly intended for agriculture employing plastic mulching.

Description

la présente invention concerne un appareil qui, instalié entre le système d'attelage trois points et l'outil attelé permet de maintenir ou de rectifier l'alignement de l'outil tracté par rapport au tracteur. the present invention relates to an apparatus which, installed between the three-point hitch system and the hitched implement, makes it possible to maintain or correct the alignment of the towed implement relative to the tractor.

les outils agricoles non auto-moteurs sont attelés directement au système trois points des tracteurs. Si ce montage donne toute sati sf action dans le sens longitudinal il n'en est pas de même dans lesens latéral. En effet dans le cas de terrains en devers, meme faible, l'outil tracté n'étant pas tenu de façon rigide a tendance a déraper dans le sens de la pente.Certains outils corne les charrues sont équipés de systémes anti devers, mais dans la majorité des cas rien nta été prévu, et le glissement des outils pose de serieux problèmes surtout dans le cas de semis ou de travaux utilisant des paillages plastiques
A l'heure actuelle, les agriculteurs confrontés a ce problème: soit le néglige et font un mauvais travail, soit trichent sur la longueur des bras d'attelage du tracteur avec le gros inconvénient d'être obligé de travailler toujours dans le même sens ou de changer manuellement le coté de réglage des bras d'attelage a chaque demi tour.
non-self-propelled agricultural implements are directly coupled to the tractor's three-point system. If this arrangement gives full satisfaction in the longitudinal direction, it is not the same in the lateral directions. In fact, in the case of slopes, even weak, the towed implement is not held rigidly tends to skid in the direction of the slope. Some tools horn the plows are equipped with anti-tilt systems, but in the majority of the cases nothing was planned, and the sliding of the tools poses serious problems especially in the case of sowing or work using plastic mulches
At the present time, farmers confronted with this problem: either neglect it and do a bad job, or cheat on the length of the tractor coupling arms with the big disadvantage of being forced to always work in the same direction or to manually change the adjustment side of the coupling arms at each half turn.

Cet appareil a donc pour but de permettre de modifier l'alignement tracteur-outil tracté à tout moment, sans effort, ans un sens ou dans l'autre et de la valeur de l'angle désiré. The purpose of this apparatus is therefore to allow the tractor-towed implement alignment to be changed at any time, without effort, in one direction or the other and by the value of the desired angle.

Cet appareil s'adapte à tous les tracteurs agricoles ayant un attelage trois points monté a l'arrière, de catégorie I, catégorie 2 ou catégorie 3, seules les dimens-- sions changent. This device is suitable for all agricultural tractors with a rear mounted three-point hitch, category I, category 2 or category 3, only the dimensions change.

le système de réglage permet d'atteler n'importe quel outil. Son faible poids ( moins de 100 kilos) et son faible encombrement ( longueur moyenne 320 millimètres) ne changent en rien lescaractéristiques de 1'attelage du tracteur. Sa facilité d'utilisation permet de le laisser en place en permanence même quand son utilité n'est pas indispensable.  the adjustment system allows any tool to be coupled. Its light weight (less than 100 kilos) and its small size (average length 320 millimeters) do not in any way change the characteristics of the tractor coupling. Its ease of use allows it to be left in place permanently even when its usefulness is not essential.

Cet appareil utilise l'énergie hydraulique par l'intermédiaire de la pompe hydraulique et d'un distributeur hy hydraulique du tracteur. This device uses hydraulic energy through the hydraulic pump and a hy hydraulic distributor of the tractor.

Cet appareil se compose de:
A- D'une traverse (2) supportant un système fixe de lial- son au troisiéme point du tracteur(7), et un système articulé (3) et réglable en longueur pour la liaison avec le point d'attelage haut de l'outil tracté(8) - voir figures
I et 2 B- De deux montants (I) réglables en largeur par toles boulonnées (II) , supportant chacun un système fixe pour liaison avec les bras du tracteur (9) et un système de glissière articulée (5) réglable hydrauliquement en longueur assurant la liaison avec les points d'attelage bas de l'outil tracté (I0) voir figures I et 2.
This device consists of:
A- A cross member (2) supporting a fixed connection system at the third point of the tractor (7), and an articulated system (3) and adjustable in length for the connection with the top coupling point of the towed implement (8) - see figures
I and 2 B- Two uprights (I) adjustable in width by bolted sheets (II), each supporting a fixed system for connection with the tractor arms (9) and an articulated slide system (5) hydraulically adjustable in length ensuring the connection with the lower coupling points of the towed implement (I0) see Figures I and 2.

C- les deux vérins double effet (6)montés en série, ce qui fait que quand l'un s'allonge l'autre se raccourcit de la même longueur, le distributeur hydraulique complété par un clapet & nti retour perxi.et le blocage dan 3 ntimpor- te quelle position. Ces vérins assurent le fonctionnement de l'appareil basé simplement sur la variation de longueur des bras d'attelage - voir figure 3 et 4
les liaisons tracteur- appareil anti devers- outil tracté se font par des broches cylindriques (I2). les alésa- ges de l'appareil anti devers coté outil tracté sont montés sur rotule (4) pour reprendre les défauts d'alignement dus au principe meme du fonctionnement de l'appareil.
C- the two double-acting cylinders (6) mounted in series, which means that when one lengthens the other shortens by the same length, the hydraulic distributor completed by a valve & nti perxi return and blocking dan 3 doesn’t matter what position. These jacks ensure the operation of the device based simply on the variation in length of the coupling arms - see Figure 3 and 4
the tractor-anti-dumping device-towed implement connections are made by cylindrical pins (I2). the bores of the anti-tilt device on the towed implement side are mounted on a ball joint (4) to take up alignment faults due to the very principle of the operation of the device.
