Abstract
Description
La présente invention concerne un perfectionnement aux têtes d'attelage pour charrues et en particulier un perfectionnement aux tetes d'attelage comportant, incorporée dans la tête, une articulation permettant un mouvement de la charrue par rapport au systeme d'attelage sur le tracteur. The present invention relates to an improvement to the coupling heads for plows and in particular to an improvement to coupling heads comprising, incorporated in the head, an articulation allowing movement of the plow relative to the coupling system on the tractor.
Ce type de têtes d'attelage permet de tirer la charrue au moyen d'un axe unique sensiblement perpendiculaire au sol, interposé entre la barre d'attelage constituant un palonnier et le corps de l'avant-train sur lequel se fixe le bâti de la charrue. This type of coupling head makes it possible to pull the plow by means of a single axis substantially perpendicular to the ground, interposed between the coupling bar constituting a lifting beam and the body of the front end on which the frame of the plough.
Ce type de têtes d'attelage est connu par le document FR-A-2 617 365 qui presente une barre d'attelage articulée entre deux plaques entretoisées qui servent d'éléments d'avant-train à la charrue. Le palonnier est guidé entre les deux plaques et autour d'un axe d'articulation sensiblement vertical qui confère à la charrue, en position normale de travail, une liberté de mouvement derrière le tracteur ; la charrue, par ce dispositif, s'apparente à une charrue trainée, ou encore à une remorque. Ce mouvement est limité par des entretoises qui séparent les deux plaques de guidage du palonnier ou par un système avec une butée interposée entre les deux plaques et disposée dans un orifice specialement amenage sur le palonnier, en forme de croix. This type of coupling head is known from the document FR-A-2 617 365 which presents a coupling bar articulated between two braced plates which serve as fore-end elements to the plow. The lifter is guided between the two plates and around a substantially vertical articulation axis which gives the plow, in normal working position, freedom of movement behind the tractor; the plow, by this device, is similar to a trailed plow, or even to a trailer. This movement is limited by spacers which separate the two guide plates of the lifter or by a system with a stop interposed between the two plates and placed in an orifice specially fitted on the lifter, in the shape of a cross.
La tête d'attelage décrite dans ce document concerne les charrues portées, dont le nombre de socs est généralement limité. Pour permettre le transport sur route de la charrue, cette derniere et en particulier son avant-train, composé des deux plaques entretoisées, se verrouille sur le palonnier par un simple appui provoqué par le poids et la charrue, et ainsi supprimer toute possibilité de mouvement autour de l'axe d'articulation. Ce verrouillage s'effectue automatiquement lorsque l'on releve la charrue. The coupling head described in this document relates to mounted plows, the number of coulters of which is generally limited. To allow the plow to be transported on the road, the latter and in particular its front end, made up of two braced plates, is locked on the lifting beam by a simple press caused by the weight and the plow, and thus eliminating any possibility of movement around the axis of articulation. This locking takes place automatically when the plow is raised.
Un tel dispositif ne permet pas le transport de charrues équipées d'une roue porteuse disposée généralement a l'arriere du bâti. En effet, pour ce type de charrue, il n'est pas possible d'obtenir un verrouillage automatique de l'avant-train puisque le bâti de la charrue reste, pour le transport, dans une position sensiblement horizontale en appui sur sa roue arrière, de sorte que l'avant-train n'est pas verrouillé par rapport au palonnier puisque le poids de la charrue n'agit plus dans le meme sens et ainsi la charrue peut, pendant le transport, pivoter autour de l'axe d'articulation vertical intégré dans la tête. Such a device does not allow the transport of plows equipped with a load wheel generally disposed at the rear of the frame. Indeed, for this type of plow, it is not possible to obtain an automatic locking of the front end since the frame of the plow remains, for transport, in a substantially horizontal position bearing on its rear wheel , so that the front end is not locked relative to the lifter since the weight of the plow no longer acts in the same direction and thus the plow can, during transport, pivot around the axis of vertical articulation integrated in the head.
La présente invention a pour objet un perfectionnement à ce type de tête d'attelage permettant le transport de charrues équipées d'une roue support disposée généralement à l'arrière. The present invention relates to an improvement to this type of coupling head allowing the transport of plows equipped with a support wheel generally disposed at the rear.
La charrue selon l'invention, comporte une tête d'attelage munie d'un palonnier enserré entre deux plaques constituant l'avant-train de la charrue ; le palonnier étant articulé par une lumiere longitudinale, autour d'un axe sensiblement vertical situé sur l'axe médian longitudinal du tracteur, procurant un mouvement de rotation autour de cet axe, mouvement qui est limité par un systeme a au moins une buée ; ledit palonnier étant également mobile selon l'axe longitudinal médian, entre les deux plaques, guidé par l'axe d'articulation vertical ; des moyens de blocage du mouvement axial du palonnier étant solidaires d'au moins une des plaques constituant 1 'avant-train. The plow according to the invention comprises a coupling head provided with a spreader clamped between two plates constituting the front end of the plow; the lifter being articulated by a longitudinal light, around a substantially vertical axis located on the longitudinal median axis of the tractor, providing a rotational movement around this axis, movement which is limited by a system has at least one mist; said spreader also being movable along the median longitudinal axis, between the two plates, guided by the vertical articulation axis; means for blocking the axial movement of the lifter being secured to at least one of the plates constituting one front end.
Selon une premiere disposition de l'invention, les moyens de blocage du mouvement axial longitudinal du palonnier sont constitués d'une cheville centrale interposée entre ledit palonnier et l'une au mois des plaques formant l'avant-train, en amont de cet avant-train, sur l'axe longitudinal médian. According to a first arrangement of the invention, the means for blocking the longitudinal axial movement of the spreader consist of a central pin interposed between said spreader and one in the month of the plates forming the front end, upstream of this front -train, on the median longitudinal axis.
Selon une autre -possibilite- de l'invention, les moyens de blocage du mouvement axial longitudinal, sont constitués de deux chevilles disposées de part et d'autre de l'axe longitudinal médian, emprisonnant le palonnier contre le systeme de butées de limitation du mouvement de pivotement autour de l'axe vertical d'articulation. According to another - possibility - of the invention, the means for blocking the longitudinal axial movement, consist of two pins arranged on either side of the median longitudinal axis, trapping the lifter against the system of stops for limiting the pivoting movement around the vertical axis of articulation.
L'invention sera encore illustrée a l'aide de la description suivante et des dessins annexes, donnés a titre indicatif, et dans lesquels - la figure 1 est une vue de dessus schématique d'une charrue selon l'invention dont la tête d'attelage est representée avec la plaque inferieure seule, située sous le palonnier qui correspond à la barre d'attelage du tracteur, en position normale de travail - la figure 2 est une vue de côte de la charrue montrant essentiellement les deux plaques qui enserrent le palonnier - la figure 3 illustre la tête d'attelage en position normale de transport, munie des moyens de blocage du mouvement axial longitudinal du palonnier - la figure 4 illustre un second mode de réalisation de l'invention. The invention will be further illustrated with the aid of the following description and of the accompanying drawings, given for information only, and in which - FIG. 1 is a schematic top view of a plow according to the invention, the head of which coupling is shown with the lower plate alone, located under the lifter which corresponds to the tractor drawbar, in normal working position - Figure 2 is a side view of the plow essentially showing the two plates which enclose the lifter - Figure 3 illustrates the coupling head in normal transport position, provided with means for blocking the longitudinal axial movement of the lifter - Figure 4 illustrates a second embodiment of the invention.
Telle que représentée figure 1, la charrue est constituée d'une tête d'attelage 1 et d'un bati 2 supportant les socs 3 ; le bâti 2 étant relié à la tette, selon le type de charrue, par un arbre 4 situé sur l'axe longitudinal médian du tracteur non représenté. As shown in Figure 1, the plow consists of a coupling head 1 and a frame 2 supporting the plowshares 3; the frame 2 being connected to the tette, depending on the type of plow, by a shaft 4 located on the median longitudinal axis of the tractor not shown.
La tête d'attelage comporte une barre d'attelage 6 ou palonnier fixé de façon classique, aux bras B de relevage du tracteur. The coupling head comprises a coupling bar 6 or lifter fixed in a conventional manner, to the lifting arms B of the tractor.
La partie arrière du bâti 2 comporte un système de roue 7, non détaillé, qui sert notamment de support arrière a la charrue, pour le transport. The rear part of the frame 2 comprises a wheel system 7, not detailed, which in particular serves as a rear support for the plow, for transport.
Ce palonnier 6 se présente sous la forme d'un losange tronqué aux extrémités, au niveau des bras B d'attelage du tracteur. La partie centrale de ce losange, comporte, centrée sur l'axe longitudinal 5 une lumière 8. This lifter 6 is in the form of a truncated diamond at the ends, at the level of the tractor coupling arms B. The central part of this rhombus comprises, centered on the longitudinal axis 5, a lumen 8.
Ce palonnier 6 est positionne et guidé entre deux plaques 9, figure 2, de forme sensiblement rectangulaire ; ces plaques 9 sont séparées par des entretoises 10 et 11 situes a l'carrière du palonnier de part et d'autre de l'axe longitudinal 5, et 12 et 13 situes à l'avant du palonnier de part et d'autre dudit axe 5, toutes sensiblement dans les angles des plaques 9. This lifting beam 6 is positioned and guided between two plates 9, Figure 2, of substantially rectangular shape; these plates 9 are separated by spacers 10 and 11 located at the quarry of the lifter on either side of the longitudinal axis 5, and 12 and 13 located at the front of the lifter on either side of said axis 5, all substantially in the corners of the plates 9.
La figure 2 montre, de côté, la tete d'attelage. On remarque le palonnier 6 enserré entre les plaques 9. La plaque supérieure 9s comporte, selon le type de charrue, un moyeu 4a qui reçoit l'arbre 4 assurant la liaison entre la tête d'attelage 1 et le bati 2 de la charrue. Figure 2 shows, from the side, the coupling head. Note the spreader 6 sandwiched between the plates 9. The upper plate 9s comprises, depending on the type of plow, a hub 4a which receives the shaft 4 ensuring the connection between the coupling head 1 and the frame 2 of the plow.
Sur la figure 1, une seule plaque 9 apparait ; il s'agit de la plaque situee sous le palonnier. Un axe d'articulation 14, sensiblement vertical, est interposé entre les deux plaques 9, fixé à ces plaques. Cet axe 14 est disposé sur l'axe longitudinal médian 5, en arrière du centre de la plaque 9, et il est disposé dans la lumière 8 aménagée au centre du palonnier. In Figure 1, a single plate 9 appears; this is the plate located under the lifter. A substantially vertical hinge pin 14 is interposed between the two plates 9, fixed to these plates. This axis 14 is disposed on the median longitudinal axis 5, behind the center of the plate 9, and it is disposed in the lumen 8 arranged in the center of the lifter.
Le palonnier est susceptible de pivoter autour de cet axe d'articulation 14 ; son mouvement est cependant limité par les entretoises 10 à 13 qui constituent un système de butée. The lifter is capable of pivoting about this articulation axis 14; its movement is however limited by the spacers 10 to 13 which constitute a stop system.
Le palonnier 6 présente également la possibilité de se déplacer selon l'axe longitudinal médian 5, guidé par sa lumiere 8, sur l'axe 14. Le mouvement longitudinal du palonnier 6 par rapport a l'axe 14 est limité d'un côté par la partie arrière 8a de la lumière et, de l'autre côté par les entretoises 10 et 11 qui viennent en contact avec les faces arrière 6a du palonnier, figure 3. The lifter 6 also has the possibility of moving along the median longitudinal axis 5, guided by its light 8, on the axis 14. The longitudinal movement of the lifter 6 relative to the axis 14 is limited on one side by the rear part 8a of the light and, on the other side by the spacers 10 and 11 which come into contact with the rear faces 6a of the lifter, FIG. 3.
Lorsque les faces arrière 6a du palonnier sont en contact avec les entretoises 10 et 11, le bâti de la charrue n'est plus susceptible de mouvement par rapport au tracteur des moyens de blocage permettent de conserver et de maintenir cette position. Ces moyens de blocage sont détaillés figures 3 et 4. When the rear faces 6a of the lifter are in contact with the spacers 10 and 11, the frame of the plow is no longer capable of movement relative to the tractor locking means make it possible to preserve and maintain this position. These blocking means are detailed in FIGS. 3 and 4.
On a représenté, figure 3, un premier mode de réalisation des moyens de blocage du mouvement axial longitudinal du palonnier 6 par rapport à l'avant-train de la charrue constitué par les plaques 9. Ces moyens sont constitués d'une patte 15 située à l'avant du palonnier 6, comme il apparaît également figure 1. Cette patte 15 comporte un orifice 16 qui correspond, lorsque le palonnier est en contact avec les butées entretoises 10 et 11, avec des orifices 17 aménages dans les deux plaques 9 de façon a permettre l'introduction d'une cheville 18 de verrouillage du palonnier. FIG. 3 shows a first embodiment of the means for blocking the longitudinal axial movement of the lifter 6 relative to the front end of the plow formed by the plates 9. These means consist of a lug 15 located at the front of the lifter 6, as it also appears in FIG. 1. This lug 15 has an orifice 16 which corresponds, when the lifter is in contact with the spacer stops 10 and 11, with orifices 17 arranged in the two plates 9 of so as to allow the introduction of a peg 18 for locking the lifter.
La position de cette patte 15, à l'avant du palonnier 6, permet un verrouillage aisé, pour le conducteur du tracteur, sans avoir a descendre de son siège puisque la cheville 18 se situe en avant de la tete d'attelage de la charrue, derrière le siège du conducteur. The position of this tab 15, at the front of the lifter 6, allows easy locking, for the tractor driver, without having to get down from his seat since the pin 18 is located in front of the coupling head of the plow , behind the driver's seat.
On a représenté, figure 4, un second mode de réalisation. Les plaques 9 comportent des orifices 19 et 20 disposés de part et d'autre de l'axe médian 5, lesquels orifices sont destinés à recevoir des chevilles 21 qui immobilisent le palonnier 6 dans sa position telle que représentée, c'est-à-dire en contact avec les butéesentretoises 10 et 11. Les chevilles 21 sont en contact avec les faces avant 6b du palonnier 6. Ces chevilles sont commodes à mettre en place depuis le poste du conducteur, puisqu'elles se situent elles aussi, dans la partie avant de la tête d'attelage, derrière le siège du conducteur. There is shown, Figure 4, a second embodiment. The plates 9 include orifices 19 and 20 arranged on either side of the median axis 5, which orifices are intended to receive pins 21 which immobilize the lifter 6 in its position as shown, that is to say say in contact with the spacer stops 10 and 11. The pins 21 are in contact with the front faces 6b of the lifter 6. These pins are convenient to put in place from the driver's position, since they are also located in the part front of the coupling head, behind the driver's seat.
