The implement-carrying bar 2 can pivot about a second axis Z-W perpendicular to the first axis X-Y under the action of a double-acting jack 4, the axis of which is contained in a vertical plane passing through said first axis and pivotable about the latter.

Description

La présente invention est relative à un porte-outil avant pour tracteur agricole. The present invention relates to a front tool holder for an agricultural tractor.

Actuellement, on fixe des porte-outils à l'avant des tracteurs agricoles pour préparer le sol en vue d'une opération qui sera effectuée par des outils situés à l'arrière du tracteur. De cette façon, deux opérations distinctes peuvent être réalisées en un seul passage. Currently, tool holders are attached to the front of agricultural tractors to prepare the soil for an operation to be performed by tools located at the rear of the tractor. In this way, two separate operations can be carried out in a single pass.

Ainsi, on connaît un appareil comportant un bâti rigide fixé à l'avant du tracteur sous lequel est disposé un cadre supportant un rouleau pouvant pivoter par rapport audit bâti autour d'un axe vertical situé en avant dudit rouleau. Thus, there is known an apparatus comprising a rigid frame fixed to the front of the tractor under which is disposed a frame supporting a roller which can pivot relative to said frame around a vertical axis located in front of said roller.

Naturellement, un tel appareil ne peut être utilisé qu'à la condition que le tracteur soit muni à l'avant d'un système de relevage ce qui n'est pas le cas pour la plupart des tracteurs. Naturally, such an apparatus can only be used on condition that the tractor is provided at the front with a lifting system which is not the case for most tractors.

Par ailleurs, il est nécessaire de charger l'appareil à l'aide de gueuses -ou de parpaings, dont la masse dépend de l'état et-de la nature du sol, pour que l'outil produise l'effet désiré avec tous les inconvénients que cela présente. In addition, it is necessary to charge the device using pigs - or breeze blocks, whose mass depends on the state and - the nature of the ground, so that the tool produces the desired effect with all the disadvantages that this presents.

La présente invention, qui remédie à ces inconvénients, est relative à un porte-outil du genre décrit ci-dessus, c'està-dire comportant un bâti et une barre porte-outil pouvant pivoter autour d'un axe vertical situé en avant de l'outil et elle est remarquable en ce que la barre porte-outil peut pivoter autour d'un second axe, perpendiculaire au premier,sous l'effet d'un vérin à double effet dont l'axe est contenu dans un plan vertical passant par ledit premier axe et pouvant pivoter autour de ce dernier. The present invention, which overcomes these drawbacks, relates to a tool holder of the kind described above, that is to say comprising a frame and a tool holder bar which can pivot around a vertical axis located in front of the tool and it is remarkable in that the tool bar can pivot around a second axis, perpendicular to the first, under the effect of a double-acting cylinder whose axis is contained in a passing vertical plane by said first axis and being able to pivot around the latter.

L'invention sera mieux comprise par la description qui va suivre, faite en se référant au dessin annexé à titre d'exemple indicatif seulement, sur lequel
la figure 1 est une vue en élévation montrant un tracteur équipé du porte-outil conforme à l'invention
la figure 2 est une vue analogue à celle 1 montrant la possibilité de relever l'outil ;
la figure 3 est une vue de côté, à plus grande échelle, du porte-outil ;
la figure 4 est une vue en perspective du porte-outil;
la figure 5 est une vue en coupe, à grande échelle, effectuée selon la ligne V-V de la figure 2.The invention will be better understood from the description which follows, made with reference to the accompanying drawing by way of indicative example only, in which
Figure 1 is an elevational view showing a tractor equipped with the tool holder according to the invention
Figure 2 is a view similar to that 1 showing the possibility of raising the tool;
Figure 3 is a side view, on a larger scale, of the tool holder;
Figure 4 is a perspective view of the tool holder;
FIG. 5 is a sectional view, on a large scale, taken along the line VV of FIG. 2.

De la façon connue, l'outil 1, constitué par exemple par un rouleau, est porté par une barre 2 pouvant pivoter dans un plan horizontal autour d'un axe vertical X-Y lié à un bâti 3 fixé au châssis du tracteur. In known manner, the tool 1, constituted for example by a roller, is carried by a bar 2 which can pivot in a horizontal plane around a vertical axis X-Y linked to a frame 3 fixed to the chassis of the tractor.

Selon l'invention, la barre 2 peut pivoter autour d'un axe
Z-W perpendiculaire à celui X-Y , sous l'action d'un vérin 4, à double effet.According to the invention, the bar 2 can pivot around an axis
ZW perpendicular to that XY, under the action of a double-acting cylinder 4.

L'axe du vérin 4 est contenu dans un plan passant par l'axe
X-Y et pouvant pivoter autour dudit axe.The axis of the jack 4 is contained in a plane passing through the axis
XY and able to pivot around said axis.

Le bâti 3 est fixé de façon rigide à l'avant du tracteur au moyen, par exemple, de bras 5. The frame 3 is rigidly fixed to the front of the tractor by means, for example, of arms 5.

Selon un mode de réalisation, le bâti 3 présente deux paliers 6 et 7 dans lesquels peut tourillonner un arbre 8 matérialisant l'axe X-Y. L'arbre 8 est immobilisé axialement par rapport à ses deux paliers 6 et 7; cette immobilisation n'est pas illustrée sur le dessin car elle est à la portée de l'homme de l'art. According to one embodiment, the frame 3 has two bearings 6 and 7 in which can rotate a shaft 8 embodying the axis X-Y. The shaft 8 is immobilized axially with respect to its two bearings 6 and 7; this immobilization is not illustrated in the drawing because it is within the reach of those skilled in the art.

La barre 2 est reliée à l'arbre 8 par deux bras 9, se réunissant pour former une chape 10 entre les ailes de laquelle s'insère l'extrémité inférieure dudit arbre qui présente, à cet effet, deux méplats 11, l'ensemble étant traversé par un boulon 12, matérialisant l'axe Z-W. The bar 2 is connected to the shaft 8 by two arms 9, meeting to form a yoke 10 between the wings of which is inserted the lower end of said shaft which has, for this purpose, two flats 11, the assembly being crossed by a bolt 12, materializing the axis ZW.

L'extrémité de la tige du piston du vérin 4 s'articule entre les ailes d'une chape 13,portée par la barre 2,par l'entremise d'un axe 14 tandis que l'extrémité du corps du vérin est articulée en 15 sur l'arbre 8 selon un axe parallèle à celui Z-W ou inversement. The end of the piston rod of the jack 4 is articulated between the wings of a yoke 13, carried by the bar 2, by means of a pin 14 while the end of the body of the jack is articulated in 15 on the shaft 8 along an axis parallel to that ZW or vice versa.

Deux méplats, analogues à ceux 11, peuvent être prévus sur l'arbre 8, au niveau de l'axe 15. Two flats, similar to those 11, can be provided on the shaft 8, at the axis 15.

De la description ci-dessus, il ressort notamment que, lorsque l'ensemble 1-2-9 pivote autour de l'axe X-Y,lors d'un changement de direction du tracteur T, la distance entre les axes 14 et 15 reste constante. De cette façon, l'outil 1 est appliqué contre le sol avec une force constante. From the above description, it appears in particular that, when the assembly 1-2-9 pivots around the axis XY, during a change of direction of the tractor T, the distance between the axes 14 and 15 remains constant . In this way, the tool 1 is applied against the ground with a constant force.

Pour le transport sur route,il suffit de rétracter le vérin 4 ce qui provoque le soulèvement de l'outil ( position représentée en traits mixtes sur la figure 3). For road transport, simply retract the cylinder 4 which causes the lifting of the tool (position shown in phantom in Figure 3).

Cette possibilité permet l'utilisation du porte-outil de l'invention sur des tracteurs ne comportant pas de système de relevage à 11 avant.  This possibility allows the use of the tool holder of the invention on tractors which do not have a front elevation system.

Cependant, si un tel système existe, il peut avantageusement être utilisé pour supporter l'outil. I1 suffit pour cela de fixer sur le bâti 3 les accessoires usuels tels que représentés en traits mixtes sur la figure 4. However, if such a system exists, it can advantageously be used to support the tool. I1 suffices for this to fix on the frame 3 the usual accessories as shown in phantom in FIG. 4.

Bien entendu la présente invention ne se limite pas au mode de réalisation décrit et représenté mais s'étend, au contraire, à toutes variantes de formes et dimensions.  Of course the present invention is not limited to the embodiment described and shown but extends, on the contrary, to all variants of shapes and dimensions.
