Abstract

Lateral articulation device for the forecarriage of a mounted plough, characterised in that it includes: a base piece 1 including, in its central part, at least one opening for the passage of the pivot pin; a pivoting master piece 2 including, in its central part, an oval opening 8, a piece 3 for fixing to the plough; spacers 10 being placed between the pieces 1 and 3 on the axis of the assembly bolts 4, 5 and 9.

Description

La présente invention est un dispositif qui permet une articulation latérale d'environ dix degrés à droite ou à gauche fixée sous 1' avant-train d'une charrue portée. Cela semble peu, mais efficace par rapport à une charrue rigide de classique qui forme avec le tracteur un ensemble de 6 - 8 mètres de long et plus. The present invention is a device which allows a lateral articulation of about ten degrees to the right or to the left fixed under the front end of a mounted plow. It seems little, but effective compared to a classic rigid plow which forms with the tractor a set of 6 - 8 meters long and more.

Les avantages sont les suivants
La charrue demande moins de puissance, car étant toujours bien aligne par rapport b la ligne d'avancement imposée par le tracteur (donc plus besoin du règlage dit du devers), il y a
- plus de facilité pour l'attelage
- plus de facilité surtout à contourner les poteaux ou pylones E.D.F.The advantages are as follows
The plow requires less power, because being always well aligned with respect to the line of advance imposed by the tractor (therefore no need for the so-called tilt adjustment), there is
- easier for coupling
- more ease especially around the EDF poles or pylons

- plus de facilité à finir les champs triangulaires ou les champs
dont les limites ne sont pas toujours droites.- easier to finish triangular fields or fields
whose boundaries are not always straight.

Le dispositif selon la présente invention comprend : une pièce de base comportant dans sa partie centrale au moins une ouverture pour le passage de l'axe de pivotement ; une pièce maîtresse pivotante comportant dans sa partie centrale une ouverture ovale ; une pièce de fixation à la charrue ; des entretoises étant placées entre la pièce de base et la pièce de fixation dans l'axe des b > oulons d'asseablage.  The device according to the present invention comprises: a basic part comprising in its central part at least one opening for the passage of the pivot axis; a pivoting centerpiece comprising in its central part an oval opening; a piece of attachment to the plow; spacers being placed between the base part and the fixing part in the axis of the bolting bolts.

Selon un modèle de réalisation préférentiel du dispositif de 1' inven- tion, l'ouverture ovale dans le centre de la pièce Mitresse comprend deux cavitres latérales qui autorisent et limitent le pivotement. Cette pièce maitresse comporte aussi à chacune de ces deux extrémités un axe pour l'attelage au tracteur.Dans ce mode de réalisation prrfantiel, deux boulons d'assemblage traversent l'ouverure, l'un de ces boulons d'assemblage servant d'axe de pivotement tandis qu'un autre boulon d'assemblage à les fonctions de limiter le pivotement à droite ou à gauche pourle labour et celle de bloquer la charrue dans l'ali gnemsnt du tracteur pour le transport sur route. According to a preferred embodiment of the device of the invention, the oval opening in the center of the Mitresse piece comprises two lateral cavities which allow and limit pivoting. This centerpiece also has at each of these two ends an axis for coupling to the tractor. In this prrfantiel embodiment, two assembly bolts pass through the opening, one of these assembly bolts serving as an axis swivel while another assembly bolt has the functions of limiting the swiveling to the right or left for plowing and that of locking the plow in the tractor alignment for road transport.

La figure 1 représente le dispositif d'ensemble de l'invention
La figure 2 représente le dispositif en position charrue relevée.Par le poids de la charrue, l'axe (5) va se bloquer en poussée dans la partie avant (6) de l'ouverture ovale de la pièce maitresse (2) ce qui oblige la charrue à se stabiliser dans l'alignement du tracteur (détail indispensable pour le bon retour- nement de la charrue).Figure 1 shows the overall device of the invention
Figure 2 shows the device in the raised plow position. By the weight of the plow, the axis (5) will lock in thrust in the front part (6) of the oval opening of the centerpiece (2) which forces the plow to stabilize in line with the tractor (detail essential for the correct turning of the plow).

La figure 3 représente le dispositif avec la pièce maitresse (2) en position de traction sur l'axe (4) et pivotée à droite, ce pivotement est limité par l'axe (5) dans une des cavités latérales (7) de l'ouverture ovale (8). FIG. 3 represents the device with the centerpiece (2) in the pulling position on the axis (4) and pivoted to the right, this pivoting is limited by the axis (5) in one of the lateral cavities (7) of the 'oval opening (8).

La figure 4 est une vue èclat8e des différentes pièces du dispositif préféren- tiel.Figure 4 is an exploded view of the various parts of the preferred device.

La figure 5 représente une variante du dispositif qui comprend comme la prdeé- dante : une pièce de base (1) ; une pièce maîtresse (2) ; une pièce de fixation à la charrue (9). Pour ce type de réalisation, un seul axe (4) suffit. Le pivotement étant limité par les boulons d'assemblage (9), la flèche (11) indique le sens de traction.FIG. 5 shows a variant of the device which, like the previous one, comprises: a basic part (1); a centerpiece (2); a part for fixing to the plow (9). For this type of embodiment, a single axis (4) is sufficient. The pivoting being limited by the assembly bolts (9), the arrow (11) indicates the direction of traction.

La figure 6 représente ce second dispositif en position charrue relevée : par le poids de la charrue, l'axe (4) va en poussée se loger dans la partie avant de l'ouverture ovale (8) de la pièce maitresse (2) et la charrue est stabilisée par les boulons d'assemblage (9) qui prennent appui ;ur l'arrière de la pièce maitresse (2). FIG. 6 represents this second device in the raised plow position: by the weight of the plow, the axis (4) will push into being housed in the front part of the oval opening (8) of the centerpiece (2) and the plow is stabilized by the assembly bolts (9) which bear; on the rear of the centerpiece (2).

Le dispositif selon l'invention est particulièrement destiné aux charrue portées.  The device according to the invention is particularly intended for mounted plows.
