Abstract
Description
La présente invention concerne les matériels agricoles du type "distri- trois buteurs d'engrais" permettant la répartition de produits solides pulvérulents ou granulés et constitués par une spire tournant dans une gaine cylindrique ou polygonale percée à sa face inférieure d'une ligne de trous laissant échapper de façon contrôlée le produit entraîné par le mouvement de la spire. The present invention relates to agricultural equipment of the "three-fertilizer stopper" type enabling the distribution of powdery or granular solid products and constituted by a turn rotating in a cylindrical or polygonal sheath pierced on its underside with a line of holes allowing the product entrained by the movement of the coil to escape in a controlled manner.
Ces appareils sont, en général, mus mécaniquement par un organe -le plus souvent un renvoi d'angle entraîné par la prise de mouvement du tracteur-situd au centre de la rampe et entraînant l'axe d'une spire droite et d'une spire gauche. Pour travailler sur une largeur excédant le gabarit routier, une articulation permet de replier les extrémités de la rampe vers l'carrière jusqu'à leur position de route où elles reposent zens horizontalement ou inclinées dans un plan pe:Prdiculaire à l'axe du véhicule porteur. Le mouvement vers l'arrière permet de plus d'inclure un dispositif de sécurité qui autorise ltéchappement de la rampe si elle vient à heurter un obstacle. These devices are, in general, mechanically moved by a member - most often a bevel gear driven by the power take-off of the tractor-situd in the center of the ramp and driving the axis of a straight turn and a left turn. To work on a width exceeding the road gauge, an articulation makes it possible to fold the ends of the ramp towards the quarry until their road position where they rest zens horizontally or inclined in a plane pe: Prdicular to the axis of the vehicle carrier. The backward movement also makes it possible to include a safety device which authorizes the escape of the ramp if it strikes an obstacle.
Ces dispositifs présentent l'inconvénient de limiter à trois fois la largeur du gabarit routier lorsque les extrémités ont leur position de route horizontale, un peu plus de trois fois cette dimension si elles ont leur position de repos inclinée. These devices have the drawback of limiting the width of the road gauge to three times when the ends have their horizontal road position, a little more than three times this dimension if they have their inclined rest position.
La présente invention se propose de permettre de donner à ces rampes une longueur plus importante en leur donnant une position de route le long du véhicule tout en conservant la possibilité de mouvement vers l'arrière en tant que dispositif de sécurité en cas de choc. The present invention proposes to make it possible to give these ramps a greater length by giving them a road position along the vehicle while retaining the possibility of rearward movement as a safety device in the event of an impact.
Cette invention consiste en une articulation double qui permet à ltextrémité de la rampe de se replier vers l'avant pour prendre sa position de route, de rester de façon stable perpendiculaire à l'axe principal du véhicule en position de travail et de s'escamoter vers l'arrière sous l'effet d'un obstacle. L'angle qui sera donne par construction à chacun des deux axes de l'articulation double déterminera l'inclinaison sur l'horizontale du plan du mouvement de repliement. Cette caractéristique de l'invention permet, d'une part, de choisir la position de route compte tenu de l'encombrement des roues du véhicule, d'autre part, d'utiliser le propre poids de la rampe pour la ramener en position de travail. Eventuellement ce mouvement pourra être renforcé par un ou plusieurs ressorts de rappel. This invention consists of a double articulation which allows the end of the ramp to fold forward to take its road position, to remain stably perpendicular to the main axis of the vehicle in the working position and to retract backwards under the effect of an obstacle. The angle which will be given by construction to each of the two axes of the double joint will determine the inclination on the horizontal of the plane of the folding movement. This characteristic of the invention allows, on the one hand, to choose the road position taking into account the size of the wheels of the vehicle, on the other hand, to use the own weight of the ramp to bring it back to the position of job. This movement could possibly be reinforced by one or more return springs.
Selon une autre caractéristique de l'invention, la partie mobile de la rampe est supportée par un hauban dont le point de fixation sur la partie du véhicule porteur est situé dans le prolongement de l'axe de l'articulation qui permet le repliement vers l'arrière. Le hauban reste tendu au cours de ce mouvement et continue donc de supporter la portion de rampe intéressée, soulageant d'autant l'articulation proprement dite. According to another characteristic of the invention, the mobile part of the ramp is supported by a guy wire whose attachment point on the part of the carrier vehicle is located in the extension of the axis of the articulation which allows the folding towards the 'back. The stay stays taut during this movement and therefore continues to support the portion of the ramp concerned, thereby relieving the articulation itself.
Selon une autre caractéristique de l'invention, le bon positionnement relatif des parties fixes et mobiles est obtenu par des pièces en saillie venant se loger dans des logements évasés de la partie correspondante. According to another characteristic of the invention, the correct relative positioning of the fixed and mobile parts is obtained by projecting parts which are housed in flared housings of the corresponding part.
Notamment, des paliers en forme de demi-coquilles pourront venir prendre appui sur chacun des deux axes pour limiter les effets de porte-à-faux qui seraient préjudiciables à la solidité de l'ensemble.In particular, bearings in the form of half-shells may come to bear on each of the two axes to limit the effects of overhangs which would be detrimental to the solidity of the assembly.
Le dessin annexé représente l'articulation double, objet de l'invention, montée sur une rampe d'épandage dont seule la gaine cylindrique est indiquée. The appended drawing represents the double articulation, object of the invention, mounted on a spreading ramp of which only the cylindrical sheath is indicated.
Tel qu'il est représenté, le dispositif comporte un axe 2 tournant dans les deux paliers 3 et 4 solidaires de la partie fixe de la gaine 1 mais dans lesquels il ne peut coulisser du fait de la présence d'un- dispositif quelconque non représenté. A son extrêmité supérieure, il porte une pièce de liaison 5 qui maintient un second axe 6 . Deux paliers 7 et 8 solidaires de I'extrêmitd mobile 9 de la rampe permettent la rotation de celle-ci autour de l'axe 6.Le palier ouvert 10 maintient ltextrêmité de l'axe 6 pendant ce mouvement de rotation. En;position travail, lorsque les sections 1 et 9 de la rampe sont dans le prolongement l'une de l'autre, le palier ouvert 11 vient lui aussi en appui sur l'axe 2 sans gêner le mouvement de rotation dans les palier 3 et 4 de tout l'ensemble 2, .5, 6, 7, 8, 9, 11. As shown, the device comprises an axis 2 rotating in the two bearings 3 and 4 integral with the fixed part of the sheath 1 but in which it cannot slide due to the presence of any device not shown . At its upper end, it carries a connecting piece 5 which maintains a second axis 6. Two bearings 7 and 8 integral with the movable end 9 of the ramp allow the latter to rotate about the axis 6. The open bearing 10 maintains the end of the axis 6 during this rotational movement. In the working position, when sections 1 and 9 of the ramp are in line with one another, the open bearing 11 also comes to bear on the axis 2 without interfering with the rotational movement in the bearings 3 and 4 of the whole set 2, .5, 6, 7, 8, 9, 11.
L'ensemble est monté de telle sorte que le plan des axes des deux pièces 2 et 6 soit sensiblement confondu avec la section de la gaine de la rampe, les pièces 3 et 4 vers l'avant, par exemple. Pour passer de la position de travail décrite ci-dessus à la position de route, I'opérateur fera pivoter manuellement ou par l'action d'un dispositif hydraulique facilement aménageable, l'ensemble mobile dans les paliers 3 et 4, jusqu'à ce que la partie mobile 9 de la rampe prenne une position perpendiculaire à la partie fixe 1. L'angle donné par construction à l'axe 2 par rapport à la verticale, impose à la partie mobile 9 de la rampe dans cette position de route une position inclinée qui sera éventuellement utile pour éviter qu'elle bute contre la roue du véhicule et permettre à l'engin de rester à l'intérieur du gabarit routier. The assembly is mounted such that the plane of the axes of the two parts 2 and 6 is substantially coincident with the section of the sheath of the ramp, the parts 3 and 4 forwards, for example. To move from the working position described above to the road position, the operator will rotate manually or by the action of an easily adaptable hydraulic device, the mobile assembly in bearings 3 and 4, up to that the mobile part 9 of the ramp takes a position perpendicular to the fixed part 1. The angle given by construction to the axis 2 with respect to the vertical, imposes on the mobile part 9 of the ramp in this road position an inclined position which may be useful to prevent it from abutting the vehicle wheel and allowing the machine to remain inside the road gauge.
Repartant de la position de travail où les deux portions de la rampe sont dans le prolongement l'une de l'autre, la portion mobile 9 peut également se replier vers l'arrière, les paliers 7 et 8 tournant autour de l'axe 6. maintenu en place par la pièce de liaison 5 et la pièce d'appui 10. Starting from the working position where the two portions of the ramp are in line with one another, the movable portion 9 can also fold back, the bearings 7 and 8 rotating around the axis 6 held in place by the connecting piece 5 and the support piece 10.
De la possibilité quta la partie mobile de la rampe de se replier aussi bien vers l'avant que vers l'arrière découlel'avantage de n'avoir d'autre limite à la longueur de la rampe que la longueur du véhicule porteur
On ne sortirait pas des limites de l'invention en inversant les positions
des axes et des paliers ce qui ne modifierait pas le mouvement relatif
des pièces. The advantage that the movable part of the ramp can fold both forwards and backwards results in the advantage of having no other limit to the length of the ramp than the length of the carrier vehicle
We would not go beyond the limits of the invention by reversing the positions
axes and bearings which would not change the relative movement
pieces.
