Description

DISPOSITIF DE CAPTURE, DE GUIDAGE ET DE RELEVA6E DE FILS DE PALISSAGE D'UNE VEGETATION PALISSEE DEVICE FOR CAPTURING, GUIDING AND LIFTING THREADS OF THREADS OF A PALISSE VEGETATION
La présente invention concerne un dispositif de capture, de guidage, de relevage de fils d'une végétation lorsque celle-ci est palissée.The present invention relates to a device for capturing, guiding, lifting son of vegetation when it is trellised.
La description qui va suivre est établie en retenant comme exemple la vigne car le dispositif selon l'invention y trouve une application directe, particulièrement intéressante. Cet exemple n'est néanmoins pas limitatif des applications concernées.The description which follows is established by taking as an example the vine since the device according to the invention finds a direct application there, particularly interesting. This example is nonetheless not limiting of the applications concerned.
Dans le cas de la vigne, on sait que les ceps ont une végétation palissée. En effet, les ceps sont alignés suivant un axe de plantation et des piquets sont régulièrement espacés entre ces ceps. Des fils sont tendus entre ces piquets d'un bout à l'autre du rang. Ces fils sont doubles et enserrent la végétation, de part et d'autre en sorte de faire une paroi de végétation, au dessus des ceps. Des liens, par exemple des agrafes, tiennent ces deux fils avec un écartement limité en sorte d'interdire à la végétation d'échapper. De plus, ces liens permettent de maintenir les fils à la hauteur souhaitée par rapport aux piquets qui les supportent.In the case of the vine, we know that the vines have a trellised vegetation. Indeed, the vines are aligned along a planting axis and stakes are regularly spaced between these vines. Wires are stretched between these stakes from one end of the row to the other. These wires are double and enclose the vegetation on both sides so as to make a wall of vegetation, above the vines. Links, for example staples, hold these two wires with a limited spacing so as to prevent the vegetation from escaping. In addition, these links make it possible to maintain the wires at the desired height relative to the stakes which support them.
Les grappes de raisins se forment en partie inférieure et sont vendangées en fin d'été voire début de l'automne pour la plupart des vignobles. Ensuite la taille intervient en cours d'hiver. Durant cette phase, les fils sont abaissés au pied des piquets après retrait des liens ou bris des agrafes. Les sarments sont alors coupés pour ne laisser que la tige la plus vigoureuse. De cette tige, les bourgeons forment des tiges vertes qui poussent très vite au printemps, sans pouvoir se tenir par elles-mêmes. Ces tiges se courbent vers le sol.The grape clusters form in the lower part and are harvested in late summer or even early fall for most vineyards. Then pruning takes place during winter. During this phase, the wires are lowered at the base of the stakes after removing the links or breaking the staples. The branches are then cut to leave only the most vigorous stem. From this stem, the buds form green stems that grow very quickly in the spring, without being able to stand by themselves. These stems bend towards the ground.
Une fois suffisamment poussées, il faut relever ces tiges vertes pour les palisser. En effet, ce relevage dégage l'espace inter rangs, permet de relever la végétation dans son ensemble, de dégager les ceps et de faciliter la fructification.Once pushed enough, these green stems must be raised to train them. Indeed, this lifting clears the inter-row space, makes it possible to raise the vegetation as a whole, to clear the vine stocks and to facilitate fruiting.
Le relevage doit aussi s'accompagner de la remise en place des fils au fur et à mesure, immédiatement après relevage. Ces opérations ont toujours été manuelles car les mouvements nécessaires sont complexes et nombreux.The lifting must also be accompanied by the replacement of the wires as and when, immediately after lifting. These operations have always been manual because the necessary movements are complex and numerous.
Tout d'abord le relevage doit s'effectuer très délicatement car la végétation très tendre ne supporte par les frottements violents et se détériore. Ce relevage doit s'opérer dans un plan perpendiculaire au plan de palissage du rang, de bas en haut.First of all the lifting must be done very delicately because the very tender vegetation does not tolerate violent friction and deteriorates. This lifting must take place in a plane perpendicular to the trellising plane of the row, from bottom to top.
Immédiatement après, il faut relever les fils en les écartant pour ne pas qu'ils dégradent la végétation.Immediately afterwards, the wires must be lifted apart so that they do not degrade the vegetation.
Enfin, il faut rapidement serrer les deux fils pour que l'ensemble soit parfaitement tenu. On peut soulever les deux fils mécaniquement, ce qui est une solution proposée par l'art antérieur.Finally, you must quickly tighten the two wires so that the assembly is perfectly held. The two wires can be lifted mechanically, which is a solution proposed by the prior art.
De ce fait lors du soulèvement des fils, ceux-ci soulèvent également les tiges de végétations qui sont posées dessus et les redressent.Therefore during the lifting of the son, they also raise the stems of vegetation that are placed on it and straighten them.
Cette solution primaire conduit à une très forte dégradation mécanique de la végétation car il y a un frottement intense des fils sur les tiges qui arrachent également les feuilles. De plus, les fils sont soumis à de fortes contraintes pouvant conduire au bris de l'un ou des deux fils. Les piquets ont également à supporter des contraintes mécaniques pour lesquelles ils ne sont pas conçus. Si ces fils sont soulevés à la main, cette opération est particulièrement pénible et si elle est mécanisée, non seulement la dégradation est intense mais en plus le redressement de la végétation est très imparfait. Lors de l'avance le redressement de la végétation s'effectue de travers en incluant le déplacement de l'engin durant la phase de redressement, déplacement qui peut vite devenir important lorsque ledit engin se déplace rapidement, 10 à 12 Km/h. Une autre solution consiste à relever la végétation avec une vis sans fin dont le plan de travail est parallèle à celui du rang de ceps et dont l'axe est incliné de bas en haut dans le sens d'avancement.This primary solution leads to a very strong mechanical degradation of the vegetation because there is an intense friction of the wires on the stems which also tear off the leaves. In addition, the wires are subjected to strong stresses which can lead to the breakage of one or both wires. The stakes also have to withstand mechanical stresses for which they are not designed. If these wires are lifted by hand, this operation is particularly painful and if it is mechanized, not only is the degradation intense, but the recovery of the vegetation is very imperfect. During the advance, the recovery of the vegetation takes place at an angle, including the movement of the machine during the recovery phase, a movement which can quickly become significant when the said machine moves quickly, 10 to 12 km / h. another solution consists in raising the vegetation with an endless screw whose working plane is parallel to that of the row of vines and whose axis is inclined from bottom to top in the direction of advance.
Ainsi la vis tourne et remonte la végétation tandis que le tracteur avance. Dans ce cas, il existe un déplacement relatif important de la végétation par rapport à la vis avec des frottements sur une grande longueur de tige.Thus the screw turns and goes up the vegetation while the tractor advances. In this case, there is a significant relative displacement of the vegetation with respect to the screw with friction over a long length of rod.
De même, pendant la rotation de la vis, il se produit un frottement important. Il faut ensuite pouvoir relever les fils de palissage. Ceci est une opération délicate car ces fils doivent être captés au début de chaque rang. Ceci conduit généralement le conducteur à descendre pour enclencher manuellement les fils sur un dispositif de guidage à une hauteur donnée. Là aussi, il se produit un glissement des fils sur la végétation lors du passage du sol en position de palissage. De plus, la largeur est déterminée et proche de l'écartement final en sorte de pouvoir placer les liens ou les agrafes immédiatement après, ce faible écart conduit aussi à un arrachement inévitable d'une partie de végétation.Likewise, during rotation of the screw, significant friction occurs. You must then be able to raise the trellising wires. This is a delicate operation because these threads must be caught at the start of each row. This generally leads the conductor to descend to manually engage the wires on a guide device at a given height. Again, there is a sliding of the wires on the vegetation when the soil passes into the trellising position. In addition, the width is determined and close to the final spacing so that you can place the links or staples immediately after, this small gap also leads to an inevitable tearing of a part of vegetation.
Enfin l'opération de rapprochement des liens et de liage est délicate lorsque l'opération est conduite à partir d'un engin qui se déplace. Des solutions de l'art antérieur consistent à introduire des agrafes par-dessus les deux fils pour les rapprocher et les maintenir serrés. Il faut néanmoins rapprocher les fils à partir du dessus, ce qui n'est pas simple. Ces opérations s'effectuent souvent en générant des dégâts sur la végétation. Le dispositif selon la présente invention propose une solution différente qui assure un relevage en limitant de façon très importante le frottement sur la végétation par glissement, tout en assurant un relevage dans un plan perpendiculaire au plan du rang, ceci quelles que soient les variations de vitesse de l'engin de travail. De plus, le dispositif permet un relevage des fils avec une saisie automatique en début de rang, un guidage qui évite la dégradation de la végétation par un mouvement combiné d'écartement, de relevage et de rapprochement, immédiatement en aval du relevage. Enfin, le dispositif selon la présente invention permet ensuite un agrafage des deux fils ainsi remontés, en évitant tout problème de centrage des fils.Finally, the operation of bringing the links and tying together is delicate when the operation is carried out using a moving machine. Solutions of the prior art consist in introducing staples over the two wires to bring them together and keep them tight. However, it is necessary to bring the wires closer from the top, which is not easy. These operations are often carried out by generating damage to the vegetation. The device according to the present invention proposes a different solution which ensures a lifting while very considerably limiting the friction on the vegetation by sliding, while ensuring a lifting in a plane perpendicular to the plane of the row, this whatever the variations in speed. of the working machine. In addition, the device allows a lifting of the wires with an automatic entry at the start of the row, a guide which avoids the degradation of the vegetation by a combined movement of spreading, lifting and bringing together, immediately downstream of the lifting. Finally, the device according to the present invention then allows stapling of the two wires thus reassembled, avoiding any problem of centering of the wires.

- figures 8 A et 8B, des vues schématiques de l'agrafe mise en place. Sur la figure 1A, on a représenté un rang 10 de ceps de vignes 12. Ces ceps sont régulièrement espacés suivant un alignement constitué d'une succession de piquets 14.- Figures 8 A and 8B, schematic views of the staple in place. In FIG. 1A, a row 10 of vine stocks 12 has been shown. These stocks are regularly spaced along an alignment consisting of a succession of stakes 14.
Deux fils 16-1 et 16-2 sont tirés entre deux pieux 18 d'amarrage, fixés aux deux extrémités du rang. Ces deux fils 16-1 et 16-2 passent de chacun des cotés du rang de part et d'autre de chaque piquet.Two wires 16-1 and 16-2 are drawn between two mooring piles 18, fixed at the two ends of the row. These two wires 16-1 and 16-2 pass on each side of the row on either side of each stake.
Sur cette figure 1A, la végétation est au stade de la taille. Les fils ont été posés à terre et les sarments sont taillés pour ne laisser que le sarment 20 le plus vigoureux qui est rabattu à quelques yeux suivant le type de plant, suivant l'âge, suivant la qualité, ou suivant la région. Dès la remontée de la sève, la végétation se développe très rapidement et les yeux du sarment se sont transformés en bourgeons puis en tiges 22 et les feuilles naissent rapidement.In this figure 1A, the vegetation is at the pruning stage. The wires were laid on the ground and the branches are cut to leave only the most vigorous branch 20 which is folded down in a few eyes according to the type of plant, according to age, according to quality, or according to the region. As soon as the sap rises, the vegetation develops very quickly and the eyes of the branch are transformed into buds then into stems 22 and the leaves are born quickly.
En deux à trois mois, les tiges 22 atteignent des longueurs importantes, comme montré sur la figure 1B. Les fils sont toujours à terre et la végétation est passée par-dessus et se développe de façon anarchique. Les tiges trop faibles se courbent pour la plupart d'entre elles et couchent dans l'espace inter rangs. Il faut maintenant relever cette végétation et la palisser avec les deux fils prévus à cet effet. Ces actions de relevage et de palissage ont pour multiples objectifs de dégager le rang, d'éviter le contact de la végétation avec le sol, de permettre le traitement efficace de cette végétation pendant le développement, de favoriser la formation et le mûrissement des grappes de raisin. La végétation après relevage et palissage doit se trouver sensiblement suivant la représentation de la figure 1C. Les tiges sont sensiblement verticales et retenues par les fils de part et d'autre.In two to three months, the rods 22 reach significant lengths, as shown in FIG. 1B. The wires are still on the ground and the vegetation has passed over and is growing in an anarchic fashion. Most weak stems bend and lie in the inter-row space. We must now raise this vegetation and train it with the two wires provided for this purpose. These lifting and trellising actions have multiple objectives to clear the rank, to avoid contact of the vegetation with the ground, to allow the effective treatment of this vegetation during development, to promote the formation and ripening of the clusters of grape. The vegetation after lifting and trellising must be substantially as shown in Figure 1C. The rods are substantially vertical and retained by the wires on either side.
Les feuilles et les tiges se développent sans contraintes car les fils ne retiennent que les tiges principales mais n'interdissent pas la croissance des sous tiges et la pousse des feuilles.The leaves and stems develop without constraints because the threads only retain the main stems but do not prevent the growth of the under stems and the growth of the leaves.
Des liens 24, généralement des agrafes, serrent les fils pour les maintenir par rapport au poteau. Ces liens sont disposés de part et d'autre de chaque poteau, à proximité immédiate, et entre les piquets, pour éviter que les fils ne s'écartent trop sur la longueur.Links 24, generally staples, tighten the wires to hold them relative to the post. These links are arranged on either side of each post, in the immediate vicinity, and between the stakes, to prevent the wires from deviating too far along the length.
Sur la figure 2A, on a représenté, vu de dessus, un rang avec le dispositif selon l'invention, en place avant les actions de relevage et de palissage.In FIG. 2A, there is shown, seen from above, a row with the device according to the invention, in place before the lifting and trellising actions.
Sur la figure 2B, le même rang est montré après les actions de relevage et de palissage selon la présente invention. Sur la figure 3, on a représenté un châssis 30 rapporté de façon adaptée sur un véhicule agricole tel qu'un tracteur, ceci de façon connue et n'intéressant pas directement l'invention.In FIG. 2B, the same rank is shown after the lifting and trellising actions according to the present invention. In Figure 3, there is shown a chassis 30 suitably attached to an agricultural vehicle such as a tractor, this in a known manner and not directly relevant to the invention.
Ce châssis supporte de façon fixe et rigide au moins un, en l'occurrence deux sous-ensembles identiques prévus pour être disposés de part et d'autre du rang. Chaque châssis comprend une platine 32 sur laquelle sont rapportés des moyensThis chassis supports in a fixed and rigid manner at least one, in this case two identical sub-assemblies intended to be arranged on either side of the row. Each chassis comprises a plate 32 on which means are attached
34 de relevage de la végétation et des moyens de capture et de guidage du fil. Il est en outre prévu des moyens de liaison des fils de guidage.34 for lifting vegetation and means for capturing and guiding the wire. Means are also provided for connecting the guide wires.
Les moyens 34 de relevage comprennent une vis 36 montée sur un berceau 38 enThe lifting means 34 comprise a screw 36 mounted on a cradle 38 in
U, comme montré sur la figure 4. Ce berceau est rapporté sur la platine 32 au moyen d'une articulation 40 autorisant un basculement dans le plan vertical suivant la double flèche V et une orientation dans le plan horizontal suivant la double flèche H. Cette articulation est interposée entre la base 42 du U tandis que les deux branches 44 et 46 de ce U supportent la vis 36.U, as shown in FIG. 4. This cradle is attached to the plate 32 by means of an articulation 40 allowing tilting in the vertical plane along the double arrow V and an orientation in the horizontal plane along the double arrow H. This joint is interposed between the base 42 of the U while the two branches 44 and 46 of this U support the screw 36.
Ces mouvements dans le plan vertical et dans le plan horizontal sont obtenus par action de vérins double effet, respectivement 48 et 50. Ces vérins sont interposés entre la platine 32 et la base 42 du U du berceau.These movements in the vertical plane and in the horizontal plane are obtained by the action of double-acting cylinders, respectively 48 and 50. These cylinders are interposed between the plate 32 and the base 42 of the U of the cradle.
La vis 36 est entraînée en rotation au moyen d'un moteur 52, hydraulique de préférence, pour des raisons de rapport poids/compacité, de puissance, et de présence de fluide hydraulique sous pression à bord des véhicules agricoles.The screw 36 is rotated by means of a motor 52, preferably hydraulic, for reasons of weight / compactness ratio, power, and presence of pressurized hydraulic fluid on board agricultural vehicles.
La vis est particulière et dans le mode préféré de réalisation tel que représenté, il est prévu au moins deux filets en l'occurrence, quatre filets 54-1 à 54-4 parallèles, juxtaposés. Ces filets 54 ont également un profil particulier, optimisé.The screw is particular and in the preferred embodiment as shown, at least two threads are provided in this case, four threads 54-1 to 54-4 parallel, juxtaposed. These threads 54 also have a particular, optimized profile.
La vis est considérée comme étant inclinée en position de travail avec une extrémité basse EB et une extrémité haute EH.The screw is considered to be inclined in the working position with a low end EB and a high end EH.
Ainsi le fond de chaque filet 54 est à pente douce 56 vers le haut c'est-à-dire dans le sens de l'amorce et du positionnement de la végétation et à pente forteThus the bottom of each net 54 has a gentle slope 56 upwards, that is to say in the direction of the start and positioning of the vegetation and with a steep slope
58 pour former butée vers le bas en sorte de retenir les tiges comme cela sera expliqué ultérieurement.58 to form a stop downwards so as to retain the rods as will be explained later.
Cette vis présente aussi une particularité importante puisqu'elle s'inscrit dans une enveloppe conique. La pointe de ce cône étant l'extrémité basse EB. Comme le pas est constant, on comprend que les filets se trouvent de moins en moins inclinés, de bas en haut.This screw also has an important feature since it fits into a conical envelope. The tip of this cone being the low end EB. As the pitch is constant, we understand that the nets are less and less inclined, from bottom to top.
Selon un perfectionnement de l'invention et pour des raisons d'adaptabilité, le berceau 38 présente une base 42 avec des éléments télescopiques pour permettre un réglage en longueur. Quant à la vis, elle peut être réalisée sous forme de modules à emboîtement si bien que l'on peut la rallonger ou la réduire suivant les besoins sans changer le dispositif dans son ensemble. Le berceau est alors adapté à la longueur de la vis. De façon avantageuse, la vis est réalisée en matière plastique pour des raisons de contact amélioré avec la végétation, de facilité de nettoyage et d'industrialisation car le moulage permet une reproduction aisée.According to an improvement of the invention and for reasons of adaptability, the cradle 38 has a base 42 with telescopic elements to allow adjustment in length. As for the screw, it can be produced in the form of interlocking modules so that it can be lengthened or reduced as required without changing the device as a whole. The cradle is then adapted to the length of the screw. Advantageously, the screw is made of plastic for reasons of improved contact with the vegetation, ease of cleaning and industrialization because the molding allows easy reproduction.
De retour sur la figure 3, on trouve des moyens 60 de capture et de guidage des fils 16-1 et 16-2 de palissage. Ces moyens 60 de capture et de guidage sont détaillés sur les figures 5 et 6.Returning to FIG. 3, there are means 60 for capturing and guiding the wires 16-1 and 16-2 for trellising. These capture and guidance means 60 are detailed in FIGS. 5 and 6.
Ces moyens 60 de capture et de guidage comprennent des modules 62 représentés sur les figures 5A et 5B. Le module de la figure 5A est montré avec sa plaque avant retirée pour faire apparaître le détail des éléments de manoeuvre.These capture and guide means 60 comprise modules 62 shown in FIGS. 5A and 5B. The module of FIG. 5A is shown with its front plate removed to reveal the detail of the operating elements.
Ces modules 62 sont disposés sur un bras 64, lui-même orientable dans le plan vertical autour d'un axe 66 de rotation.These modules 62 are arranged on an arm 64, itself orientable in the vertical plane around an axis 66 of rotation.
Cet axe 66 est supporté par un chariot 68, monté à coulissement en translation sur un rail 70, suivant la double flèche T, voir figure 3, solidaire de la platine 32. Ce rail 70 est orienté perpendiculairement au plan du rang de vigne, parallèle à l'axe 66 de rotation. Un vérin 71, interposé entre le plateau et la platine 32 permet de déplacer en translation ce chariot 68.This axis 66 is supported by a carriage 68, mounted to slide in translation on a rail 70, along the double arrow T, see FIG. 3, secured to the plate 32. This rail 70 is oriented perpendicular to the plane of the row of vines, parallel to the axis 66 of rotation. A jack 71, interposed between the plate and the plate 32 makes it possible to move this carriage 68 in translation.
Chaque module 62 comprend une base 72, avec deux plaques formant une chape rapportée sur le bras 64. II est en outre prévu deux galets, 74-1 et 74-2, montés libres en rotation, chacun autour d'un axe 76-1 et 76-2.Each module 62 comprises a base 72, with two plates forming a yoke added on the arm 64. There are further provided two rollers, 74-1 and 74-2, mounted free in rotation, each around an axis 76-1 and 76-2.
L'axe 76-1 est supporté par l'une 78-1 des branches d'un Vé 80-1 monté à rotation autour d'un axe 82-1. Cet axe est solidaire de la base 72.The axis 76-1 is supported by one 78-1 of the branches of a Vee 80-1 rotatably mounted around an axis 82-1. This axis is integral with the base 72.
L'autre 84-1 des branches du Vé 80-1 est liée à un levier 86-1. Le montage est symétrique pour le galet 74-2.The other 84-1 of the branches of Vé 80-1 is linked to a lever 86-1. The mounting is symmetrical for the roller 74-2.
Les deux leviers 86-1 et 86-2 sont articulés par leur extrémité libre sur l'extrémité 88 de la tige 90 d'un vérin 92, double action. Ainsi, lorsque le vérin est en extension avec la tige en saillie comme représenté sur la figure 5A, les deux leviers agissent sur les branches 84-1 et 84-2 pour faire pivoter les Vé 80-1 et 80-2. Les deux branches 78-1 et 78-2 pivotent simultanément, ce qui a tendance à écarter les deux galets 74-1 et 74-2. Lorsque le vérin est en rappel awec la tige en retrait, les branches 84-1 et 84-2 pivotent dans le sens contraire et font pivoter les Vé. Les deux branches 78-1 et 78-2 pivotent simultanément dans le sens inverse et rapprochent les deux galets 74-1 et 74-2. Comme ces galets ne sont pas dans le même plan, vus de l'avant comme représenté, il y a une intersection des axes pour conduire à la formation d'une lumière 94 de guidage, visible sur la figure 5B.The two levers 86-1 and 86-2 are articulated by their free end on the end 88 of the rod 90 of a jack 92, double action. Thus, when the jack is extended with the projecting rod as shown in FIG. 5A, the two levers act on the branches 84-1 and 84-2 to rotate the Vee 80-1 and 80-2. The two branches 78-1 and 78-2 pivot simultaneously, which tends to spread the two rollers 74-1 and 74-2. When the jack is returned to the recessed rod, the branches 84-1 and 84-2 pivot in the opposite direction and rotate the Vee. The two branches 78-1 and 78-2 pivot simultaneously in the opposite direction and bring the two rollers 74-1 and 74-2 together. As these rollers are not in the same plane, seen from the front as shown, there is an intersection of the axes to lead to the formation of a guide light 94, visible in FIG. 5B.
De même, dans le mode préférentiel représenté, chaque galet a des formes optimisées en ce sens qu'il est de forme générale cylindrique avec sur le bord libre extérieur, une collerette 96, inclinée vers le corps dudit galet. La base 72 de chaque module dispose d'un bec 98 avant, qui est venu de découpe avec chacune des plaques formant chape.Similarly, in the preferred mode shown, each roller has optimized shapes in the sense that it is of generally cylindrical shape with on the outer free edge, a flange 96, inclined towards the body of said roller. The base 72 of each module has a front spout 98, which has been cut out with each of the plates forming a yoke.
Le vérin 92 est agencé de façon particulière également pour répondre à certains impératifs de sécurité qui seront détaillés dans la description du fonctionnement.The cylinder 92 is also arranged in a particular way to meet certain safety requirements which will be detailed in the description of the operation.
En effet, ce vérin 92 a son corps monté en translation par rapport à la plaque 72. Les déplacements sont limités par un ressort 93 dont la force de rappel peut être ajustée.Indeed, this jack 92 has its body mounted in translation relative to the plate 72. The displacements are limited by a spring 93 whose return force can be adjusted.
Sur les deux figures 5A et 5B, il est indiqué, en section, un des fils 16-1 ou 16-2 de palissage. Les modules 62 sont supportés par un bras 64 articulé autour d'un axe 66 et sur les figures 6A et 6B, on a représenté deux positions de ce bras équipé de deux modules. Un vérin 99 permet de régler l'inclinaison dans le plan vertical. Sur la figure 6 A, la position du bras sensiblement horizontale est dite de capture et sur la figure 6B la position inclinée est dite de guidage, les galets ayant été refermés.In the two figures 5A and 5B, it is indicated, in section, one of the wires 16-1 or 16-2 for trellising. The modules 62 are supported by an arm 64 articulated around an axis 66 and in FIGS. 6A and 6B, there are shown two positions of this arm equipped with two modules. A jack 99 makes it possible to adjust the inclination in the vertical plane. In FIG. 6A, the position of the substantially horizontal arm is said to be of capture and in FIG. 6B the inclined position is said to be of guide, the rollers having been closed.
Les modules sont en effet conservés ouverts pour cet exemple schématique. Sur les figures 7A et 7B, on a représenté des moyens 100 de liaison des fils de palissage 16-1 / 16-2.The modules are indeed kept open for this schematic example. In FIGS. 7A and 7B, means 100 are shown for connecting the trellising wires 16-1 / 16-2.
Ces moyens 100 de liaison comprennent des supports sous formes de deux potences 102 et 104. Chaque potence comprend une tête 106 et 108.These connecting means 100 comprise supports in the form of two brackets 102 and 104. Each bracket comprises a head 106 and 108.
La tête 106 est équipée d'un nez 110 comprenant une ouverture 112 sensiblement en forme de V horizontal, avec un logement 114 prévu pour recevoir une agrafeThe head 106 is equipped with a nose 110 comprising an opening 112 substantially in the form of a horizontal V, with a housing 114 provided for receiving a staple
116. Le V est orienté avec sa pointe vers l'extérieur.116. The V is oriented with its point outwards.
Au-dessus de ce nez est disposé un magasin 118 de réserve d'agrafes et au- dessus encore, des moyens 120 de distribution des ces agrafes, une par une, en l'occurrence un vérin pneumatique. La tête 108 comprend, quant à elle, uniquement une ouverture 122 en V dont la pointe est également orientée vers l'extérieur.Above this nose is arranged a magazine 118 for staples reserve and above still, means 120 for distributing these staples, one by one, in this case a pneumatic cylinder. The head 108 comprises, for its part, only an opening 122 in V whose tip is also oriented outward.
Ainsi les deux ouvertures des deux V se trouvent en face l'une de l'autre.Thus the two openings of the two Vs are located opposite one another.
Les deux fils 16-1 et 16-2 sont également représentés.The two wires 16-1 and 16-2 are also shown.
Sur la figure 7B, l'étape est celle de l'enclenchement de l'agrafe et l'on constate qu'après rapprochement des deux potences 102 et 104, les deux V forment un logement 124 dans lequel se logent les deux fils 16-1 et 16-2 de palissage.In FIG. 7B, the step is that of engaging the clip and it can be seen that after the two brackets 102 and 104 are brought together, the two Vs form a housing 124 in which the two wires 16 are housed. 1 and 16-2 of trellising.
L'agrafe 116 utilisée est particulière puisqu'elle est adaptée à l'agencement décrit ci-avant. Cette agrafe 116 comprend un corps avec une ouverture 124. Une forme en Ç est particulièrement adaptée. Ce corps comporte aussi des moyens 126 de fermeture de cette ouverture, à rappel élastique. Ces moyens 126 de fermeture sont en l'occurrence constitués d'une languette 128 déformable. Cette languette est venue de moulage en pied avec l'une des branches du Ç lorsque celle-ci est réalisée en matière plastique. Avantageusement, la languette est inclinée vers l'intérieur du C, en sorte de former arrêtoir et de ne pouvoir se plier dans l'autre sens.The clip 116 used is particular since it is adapted to the arrangement described above. This clip 116 comprises a body with an opening 124. A form in Ç is particularly suitable. This body also comprises means 126 for closing this opening, with elastic return. These closing means 126 in this case consist of a deformable tongue 128. This tongue came from the bottom molding with one of the branches of the Ç when the latter is made of plastic. Advantageously, the tongue is inclined towards the inside of the C, so as to form a retainer and not to be able to bend in the other direction.
Ainsi la languette est souple à l'introduction et résistante à la sortie de fils de palissage.Thus the tongue is flexible to the introduction and resistant to the output of trellising wires.
Des variantes peuvent comprendre un profil en Ç avec deux languettes de même type, issues chacune de l'une des branches. Ceci renforce la sécurité, la résistance et la facilité de positionnement du fil.Variants may include a C-profile with two tabs of the same type, each from one of the branches. This reinforces the security, the resistance and the ease of positioning of the wire.
Si l'on se reporte à la figure 8B, on constate que les fils, une fois les moyens d'agrafage éloignés, se positionnent l'un dans le creux du C et l'autre à l'emplanture de la languette 128, dans la partie la plus résistante. On note que l'introduction de cette agrafe est réalisée latéralement par rapport aux fils.Referring to FIG. 8B, it can be seen that the wires, once the stapling means are removed, are positioned one in the hollow of the C and the other at the root of the tongue 128, in the most resistant part. Note that the introduction of this clip is made laterally relative to the son.
Le fonctionnement du dispositif selon la présente invention est maintenant décrit en détail en regard des différentes figures, en explicitant le rδle de chacun des moyens 34 de relevage et de palissage de la végétation, des moyens 60 de capture et de guidage des fils de palissage et des moyens 100 de liaison de ces fils.The operation of the device according to the present invention is now described in detail with regard to the different figures, explaining the role of each of the means 34 for lifting and trellising the vegetation, means 60 for capturing and guiding the trellising wires and means 100 for connecting these wires.
Le dispositif monté sur un véhicule se présente en début de rang, comme montré sur la figure 2A.The device mounted on a vehicle appears at the start of the row, as shown in FIG. 2A.
Les deux vis ont un angle d'attaque légèrement divergent en sorte de se placer sous les extrémités des tiges, au plus près des extrémités. L'ensemble de la vis 36 dans son berceau 38 et du bras 64 support de modules 62 est placé en position horizontale.The two screws have a slightly divergent angle of attack so as to be placed under the ends of the rods, as close as possible to the ends. The assembly of the screw 36 in its cradle 38 and of the arm 64 for module support 62 is placed in a horizontal position.
Les deux sous-ensembles du châssis 30 sont disposés de part et d'autre du rang. La première étape est la capture des fils 16-1 et 16-2. A cet effet, chaque bras 64 est rapproché du plan médian du rang et vient placer le fil correspondant en butée sur le bec 98 de chaque module 62. Le mouvement de rapprochement est obtenu par actionnement du vérin 71 qui translate le chariot 68 sur le rail 70. Les galets 76-1 et 76-2 de chaque module sont en position ouverte, comme montré sur la figure 5A.The two sub-assemblies of the chassis 30 are arranged on either side of the row. The first step is to capture wires 16-1 and 16-2. To this end, each arm 64 is brought closer to the median plane of the row and places the corresponding wire in abutment on the spout 98 of each module 62. The movement of approach is obtained by actuation of the jack 71 which translates the carriage 68 on the rail 70. The rollers 76-1 and 76-2 of each module are in the open position, as shown in FIG. 5A.
Lorsque chaque fil 16-1 et 16-2 est entre les galets, en appui sur chaque bec 98, les vérins 92 sont actionnés et la tige est rétractée, ce qui a pour conséquence de fermer les galets et de les placer dans la position de la figure 5B. Chaque fil est capté et se place dans la lumière 94 de guidage de chaque module. Chaque bras 64 est retiré du rang entraînant le fil car celui-ci ne peut sortir de la lumière 94. Cette manoeuvre est réalisée par actionnement des vérins 71 dans le sens opposé. On note à ce niveau que lorsque la traction est exercée, le vérin 92 est immobilisé par le ressort 93, taré. Si l'effort de retrait du rang par exemple ou tout autre incident, venait à provoquer une traction supérieure à la valeur de tarage du ressort 93, le corps du vérin se déplacerait en comprimant le ressort et les galets s'ouvriraient, laissant échapper le fil avant rupture de ce dernier. En situation de fonctionnement normale, chaque fil étant guidé par une paire de modules 62, de chaque côté, le vérin 99 est actionné, ce qui provoque une inclinaison du bras 64, le module amont étant en bas et le module arrière étant relevé.When each wire 16-1 and 16-2 is between the rollers, bearing on each spout 98, the jacks 92 are actuated and the rod is retracted, which has the consequence of closing the rollers and placing them in the position of Figure 5B. Each wire is captured and is placed in the light 94 for guiding each module. Each arm 64 is removed from the row driving the wire because the latter cannot exit from the lumen 94. This maneuver is carried out by actuating the jacks 71 in the opposite direction. It is noted at this level that when the traction is exerted, the jack 92 is immobilized by the spring 93, calibrated. If the effort to withdraw the row, for example, or any other incident, would cause traction greater than the setting value of the spring 93, the cylinder body would move by compressing the spring and the rollers would open, letting the wire before breaking of the latter. In normal operating conditions, each wire being guided by a pair of modules 62, on each side, the jack 99 is actuated, which causes the arm 64 to tilt, the upstream module being at the bottom and the rear module being raised.
Au fur et à mesure de l'avancement du véhicule dans le rang, chaque fil est donc cueilli au sol par le premier module et relevé à hauteur de palissage par le second module.As the vehicle advances in the row, each wire is therefore picked from the ground by the first module and raised to trellis height by the second module.
Le fil est cueilli immédiatement en aval de l'extrémité basse EB de la vis et il est remonté sous la protection de la vis et placé à hauteur de palissage immédiatement au droit de l'extrémité haute EH de la vis 36. De la même façon, on constate que les deux fils sont maintenus écartés du rang durant ce relevage.The wire is picked immediately downstream from the low end EB of the screw and it is reassembled under the protection of the screw and placed at trellis height immediately to the right of the high end EH of the screw 36. In the same way, we see that the two wires are kept apart from the row during this lifting.
Simultanément, pendant la capture du fil, la mise en place du bras 64 des moyens de capture et de guidage du fil, la vis est également mise en service. A cet effet, les opérations sont les suivantes.Simultaneously, during the capture of the wire, the positioning of the arm 64 of the wire capture and guide means, the screw is also put into service. The operations for this are as follows.
Par actionnement du vérin 48, la vis est inclinée vers le bas par sa pointe, dans le sens d'avancement.By actuation of the jack 48, the screw is inclined downward by its point, in the direction of advance.
Par actionnement du vérin 50, l'angle d'attaque, légèrement divergent, est ajusté. Enfin, le moteur 52 est mis en marche.By actuation of the jack 50, the slightly diverging angle of attack is adjusted. Finally, the motor 52 is started.
Ceci provoque la mise en rotation de la vis 34 sur elle-même dans son berceauThis causes the screw 34 to rotate on itself in its cradle
38.38.
Lors de l'avance du véhicule, chaque vis passe par son extrémité basse sous la végétation qui se place sur les filets en fonction de la hauteur et de leur position aléatoire de pousse par rapport au rang.When advancing the vehicle, each screw passes through its lower end under the vegetation which is placed on the nets according to the height and their random position of growth in relation to the row.
Chaque tige est donc captée au plus près de son extrémité.Each rod is therefore captured as close as possible to its end.
Le cheminement de chaque est bien déterminé. La tige vient sur le fond du filet et la pente douce 56 laisse glisser la tige vers la pente 58 qui forme butée et provoque la montée de ladite tige. Le pas est calculé pour que la montée s'effectue rapidement. Le fait de disposer de quatre filets permet de traiter plusieurs tiges adjacentes tout en les remontant rapidement puisque le pas est grand.The path of each is well determined. The rod comes to the bottom of the net and the gentle slope 56 lets the rod slide towards the slope 58 which forms a stop and causes the said rod to rise. The pitch is calculated so that the climb takes place quickly. The fact of having four nets makes it possible to treat several adjacent rods while winding them up quickly since the pitch is large.
La vitesse de rotation de la vis, fonction de son pas, est asservie à celle du véhicule de façon à ce que la tige remonte dans un plan perpendiculaire au plan du rang, sans déplacement de la tige vers l'avant ou l'arrière, alors que le véhicule agricole, lui, se déplace linéairement, parallèlement au rang.The speed of rotation of the screw, depending on its pitch, is controlled by that of the vehicle so that the rod goes up in a plane perpendicular to the plane of the row, without displacement of the rod forwards or backwards, while the agricultural vehicle, it moves linearly, parallel to the row.
De plus, le pas de vis qui est grand, permet de limiter le frottement de la vis sur les tiges car la partie concernée de la tige est très courte. C'est une zone très faible, proche de l'extrémité qui est concernée, tout au long du mouvement au contact de la vis. Les meurtrissures de la vigne sont très limitées. L'angle convergent à l'extrémité haute EH de la vis permet en partie haute de la vis de se rapprocher du plan médian du rang et de rapprocher simultanément la végétation qui est guidée sur la vis.In addition, the large pitch of the screw makes it possible to limit the friction of the screw on the rods because the part concerned of the rod is very short. It is a very weak, close to the end which is concerned, throughout the movement in contact with the screw. Bruising of the vine is very limited. The converging angle at the high end EH of the screw allows the upper part of the screw to approach the median plane of the row and simultaneously bring the vegetation which is guided on the screw.
La forme conique présente également un intérêt certain puisque, à l'extrémité haute de la vis EH, la tangente au point de contact de la tige par rapport à la vis se rapproche de la verticale alors que la tangente de ce même point de contact à l'extrémité basse EB de la vis était sensiblement horizontale. Les tiges sont donc parfaitement redressées en fin de vis, prêtes à être palissées entre les deux fils qui sont relevés quasi simultanément de part et d'autre de cette végétation. Il n'y a en effet un très faible décalage dans le temps si bien que la végétation ne subit aucun dommage. La végétation est relevée et disposée entre les deux fils qui sont situés de part et d'autre de la végétation.The conical shape is also of definite interest since, at the high end of the screw EH, the tangent to the point of contact of the rod relative to the screw approaches the vertical while the tangent of this same point of contact to the low end EB of the screw was substantially horizontal. The rods are therefore perfectly straightened at the end of the screw, ready to be trellised between the two wires which are raised almost simultaneously on either side of this vegetation. There is indeed a very small time lag so that the vegetation is not damaged. The vegetation is raised and placed between the two wires which are located on either side of the vegetation.
La position des fils est parfaitement connue puisqu'ils sortent du dernier moduleThe position of the wires is perfectly known since they come out of the last module
62 à une hauteur définie.62 at a defined height.
Les moyens 100 de liaison peuvent être aisément mis en oeuvre, en aval.The connecting means 100 can be easily implemented, downstream.
Dans ce cas, il est rappelé que le véhicule progresse et qu'il faut disposer une agrafe qui enserre les deux fils, de part et d'autre de chaque poteau et à intervalle régulier entre les piquets.In this case, it is recalled that the vehicle is progressing and that it is necessary to have a clip which encloses the two wires, on either side of each post and at regular intervals between the stakes.
Le problème d'agrafer de chaque côté du poteau laisse un temps d'exécution très court, de quelques dixièmes de secondes à une vitesse de 10 à 15 Km/h. Pour la phase d'agrafage, les deux potences 102 et 104 sont donc rapprochées l'une de l'autre, très rapidement.The problem of stapling on each side of the post leaves a very short execution time, of a few tenths of seconds at a speed of 10 to 15 km / h. For the stapling phase, the two brackets 102 and 104 are therefore close together, very quickly.
Chacun des V entraîne un des fils 16-1 / 16-2 qui est en face de façon à les rapprocher et à les faire pénétrer dans une même agrafe, portée par le Vé de la potence 102. Le fil 16-1 du côté de la tête 106 pénètre très rapidement dans l'agrafe 116 en abaissant la languette 128. Ce premier fil 16-1 se plaque au fond du profil en Ç de cette agrafe et se trouve entraîné jusqu'au droit du plan médian.Each of the Vs drives one of the wires 16-1 / 16-2 which is opposite so as to bring them together and make them penetrate into the same staple, carried by the Vee of the stem 102. The wire 16-1 on the side of the head 106 penetrates very quickly into the clip 116 by lowering the tongue 128. This first wire 16-1 is pressed to the bottom of the profile in Ç of this clip and is driven to the right of the median plane.
La tête 108 entraîne le second fil 16-2 et le pousse jusqu'au droit du plan médian.The head 108 drives the second wire 16-2 and pushes it to the right of the median plane.
Le croisement des deux têtes, décalé dans le sens de progression, comme montré sur la figure 7B, provoque la pénétration du second fil 16-2 dans l'agrafeThe crossing of the two heads, offset in the direction of progression, as shown in FIG. 7B, causes the penetration of the second wire 16-2 in the staple
116 qui retient déjà le fil 16-1.116 which already retains the wire 16-1.
Une fois les deux potences arrivées en fin de mouvement, elles reviennent en position initiale.Once the two brackets have reached the end of the movement, they return to the initial position.
La seconde tête 108 lâche le fil 16-2 qui se trouve retenu par la languette 128 qui s'est redressée par sa propre élasticité.The second head 108 releases the wire 16-2 which is retained by the tongue 128 which has straightened by its own elasticity.
Lorsque la première tête 106 se retire, l'agrafe 116 est retenue par le second filWhen the first head 106 is withdrawn, the clip 116 is retained by the second wire
16-2 et l'agrafe quitte le logement dans lequel elle était positionnée par simple emboîtement.16-2 and the clip leaves the housing in which it was positioned by simple interlocking.
Dès que l'agrafe a quitté son logement, le piston du vérin 120 provoque la descente d'une nouvelle agrafe 116 du magasin 118 dans ce même logement pour un nouvel agrafage.As soon as the staple has left its housing, the piston of the jack 120 causes a new staple 116 to descend from the magazine 118 into this same housing for a new stapling.
Le premier fil est prisonnier également de l'agrafe 116 et les deux fils se trouvent sensiblement dans la position représentée sur la figure 8B.The first wire is also trapped in the clip 116 and the two wires are substantially in the position shown in FIG. 8B.
On obtient un rapprochement et une liaison des fils comme recherché. Cette opération est très rapide et ne détériore pas la végétation palissée.We obtain a connection and a bond of the wires as desired. This operation is very fast and does not deteriorate the fenced vegetation.
Avantageusement, les agrafes peuvent être produites en matière plastique pour des raisons de coûts, notamment. Le dispositif selon la présente invention est particulièrement avantageux et résout de très nombreux problèmes par rapport aux agencements proposés par l'art antérieur. Advantageously, the staples can be produced from plastic for cost reasons, in particular. The device according to the present invention is particularly advantageous and solves many problems compared to the arrangements proposed by the prior art.
