Abstract

The machine for tying in support wires (1) in viticulture comprises two rollers (3) which can be moved together so that the wires approach each other and clips (2) can be fitted. The rollers have helical grooves (33, 34) which slope in opposite directions and feed the wires into horizontal central grooves (32).

Description

(3) La presente invention a pour objet, dans le domaine notamment de la(3) The subject of the present invention is, in particular in the field of

viticulture, un dispositif pour le relevage de fils dits viticulture, a device for lifting so-called wires

releveurs utilises dans une operation de palissage. lifters used in a trellising operation.

L' operation de palissage consiste a orienter la vegetation dans la direction voulue. Dans le domaine viticole, le palissage est realise par le liege de la vigne a des fils tendus sur des piquets alignes et regulierement espaces. Un rang de vigne comporte plusieurs firs, sur lesquels la vegetation est attachee lors de l' operation de liege. Par ailleurs, deux fils vent solidarises cote a cote aux extremites superieures des piquets l'un au moins desdits fils etant apte a en etre desolidarise. Ce ou ces firs, appeles fils << releveurs >> ou fils << balans >>, vent destines a enserrer la partie haute de la vegetation, la possibilite de desolidariser au moins l'un d'eux des piquets de rang facilitant l' introduction de la vegetation entre eux. Apres accrochage du ou des fils releveurs aux piquets, leur rapprochement est complete par une fixation au moyen The trellising operation consists in orienting the vegetation in the desired direction. In the viticultural domain, trellising is carried out by the cork of the vine to wires stretched on aligned stakes and regularly spaces. A row of vines contains several firs, to which the vegetation is attached during the cork operation. Furthermore, two son wind secured side by side at the upper ends of the stakes at least one of said son being able to be separated. This or these firs, called "lifting" wires or "balans" wires, wind intended to enclose the upper part of the vegetation, the possibility of separating at least one of them from the stakes of row facilitating the introduction of vegetation between them. After hooking up the lifting wire (s) to the stakes, their approximation is completed by fixing by means

d' elements amovibles tels que des agrafes. removable elements such as staples.

Les operations de relevage vent tres eprouvantes pour le The lifting operations are very demanding for the

personnel car de maniere generale elles vent realisees manuellement. personal because generally they are done manually.

Pour remedier a cet inconvenient on a propose des machines releveusespalisseuses telles que celle decrite dans le document FR 2.623.369, qui prend les fils au sol, les releve, les resserre sur To remedy this drawback, lifting and lifting machines have been proposed such as that described in document FR 2,623,369, which takes the wires from the ground, raises them, tightens them on

la vegetation puis les agrafe.vegetation then staples them.

Les utilisateurs d'une telle machine rencontre certaines difficultes, notamment lors de la prise des fils qui demeure une operation difficile et delicate. En effet, le conducteur de la machine doit diriger celle-ci tout en prenant les fils dans la vegetation, et du fait du peut de visibilite ledit conducteur doit frequemment descendre de la machine pour realiser un ajustage manuel The users of such a machine encounter certain difficulties, in particular when picking up the wires, which remains a difficult and delicate operation. Indeed, the driver of the machine must direct it while taking the wires in the vegetation, and because of the low visibility said driver must frequently get off the machine to make a manual adjustment

pour pallier la defaillance de la machine. to overcome the machine failure.

Par ailleurs, l' ensemble mecanique dedie a la prise des fils est relativement encombrant ce qui necessite de menager au bout des routes de vigne des espaces importants pour la realisation de maneuvres, ce qui est prejudiciable du point de vue economique Furthermore, the mechanical assembly dedicated to the taking of the wires is relatively bulky, which necessitates providing large spaces at the end of the vine roads for carrying out maneuvers, which is detrimental from an economic point of view.

notamment dans les crus reputes.especially in reputed vintages.

Les inconvenients lies a la prise de fils pourraient etre resolus par un guidage des fils au moyen par exemple de dispositifs dits ecarteurs, adaptables au sommet des piquet tels que ceux proposes, entre autres, dans les documents EP Q 876 756 et CE! 685 187, et qui permettent le guidage des fils releveurs et dreviter que The disadvantages linked to the taking of wires could be resolved by guiding the wires by means, for example, of so-called spacer devices, adaptable to the top of the stakes such as those proposed, among others, in documents EP Q 876 756 and CE! 685 187, and which allow the guidance of the take-up wires and to avoid that

ceux ne trainent au sol.those don't drag on the ground.

Ces dispositifs presentent toutefois l' inconvenient ne pouvoir However, these devices have the disadvantage that they cannot

etre maneuvres que manuellement.be operated only manually.

Ainsi, les dispositifs d'ecarteurs pourraient pallier les inconvenients des machines relevouses-palisseuses existantes et Thus, the retractor devices could overcome the drawbacks of existing lifting-lifting machines and

inversement, ils vent toutefois incompatibles. conversely, they are however incompatible.

Le present Demandeur a toutefois mis au point un dispositif ecarteur mobile auto repositionnable pour fils releveurs, decrit dans la demande de brevet europeen N 02 360058 non publiee a ce jour, qui est du type comportant deux branches solidarisees au piques par l'intermediaire d'un moyen support, dont les extremites libres presentent chacune un moyen de retenue d'un fil releveur, et qui vent prewes apses a prendre deux positions a savoir fermee ou les fils relevours vent rapproches l'un de l'autre, et ouverte ou lesdits fils releveurs vent eloignes l'un de l'autre, lesdites branches comportant chacune un moyen de pivotement associe a un moyen de butee, leur permettant de passer, apres liberation desdits fils relevours, de la position fermee a la position ouverte par gravite, et de la position ouverte a la position fermee par le rapprochement desdits firs, tandis que ledit moyen support comporte des moyens prews apses a permettre un guidage en translation verticale de l'extremite pivotante des branches par rapport audit support. Outre le fait que ce dispositif ecarteur offre des avantages pour un palissage manuel, il autorise un palissage mecanise. En effet, etant lies aux fils et en libre pivotement et translation, limitee toutefois, sur le piques, ils peuvent etre mancauvres par The present Applicant has, however, developed a self-repositionable mobile spreader device for lifting wires, described in European patent application N 02 360058 not published to date, which is of the type comprising two branches secured to the spikes by means of a support means, the free ends of which each have a means for retaining a take-up wire, and which wind prewes able to take two positions, namely closed or the winding son wind close to each other, and open or said wind-raising wires moved away from each other, said branches each comprising a pivoting means associated with a stop means, enabling them to pass, after release of said lifting wires, from the closed position to the open position by gravity, and from the open position to the closed position by the approximation of said firs, while said support means comprises means prews apses to allow guiding in vertical translation of the pivot end aunt of the branches with respect to said support. In addition to the fact that this spreader device offers advantages for manual trellising, it allows mechanical trellising. Indeed, being linked to the wires and in free pivoting and translation, limited however, on the spikes, they can be mancauvres by

l'intermediaire des fils relevours.through the relief wires.

Les fils relevours etant guides et ne tralnant plus au sol, il n'est plus necessaire de ramasser, ce qui permet de concevoir des relevausespalisseuses moins complexes et done moins onereuses et As the recovery wires are guided and no longer dragging on the ground, it is no longer necessary to pick up, which makes it possible to design less complex and therefore less expensive

plus gables.more gables.

Par ailleurs, la possibilite de translation verticale permet Furthermore, the possibility of vertical translation allows

aux fils de s'auto-positionner par rapport a l'agrafeuse. the wires to self-position with respect to the stapler.

Le dispositif pour le relevage de fils dits releveurs utilises dans une operation de palissage selon l' invention est du type comportant des moyens de relevage, des moyens de resserrement des fils et des moyens d'agrafage de ceux-ci, il est porte par un engin tracteur apte a enjamber le rang de vegetation a traiter, il est destine a etre utilise dans des plantations equipees de dispositifs ecarteurs du type comportant chacun deux branches solidarisees a un piques par l'intermediaire d'un moyen support, dont les extremites libres presentent chacune un moyen de retenue d'un desdits fils releveurs, et qui vent prevues apses a prendre deux positions a savoir fermee ou les fils releveurs vent rapproches l'un de l'autre, et ouverte ou lesdits fils relevours vent eloignes l'un de l'autre, lesdites branches comportant chacune un moyen de pivotement associe a un moyen de butee, leur permettant de passer, apres liberation desdits fils relevours, de la position fermee a la position ouverte par gravite, et de la position ouverte a la position fermee par le rapprochement desdits fils releveurs, tandis que ledit moyen support comporte des moyens prevus apses a permettre un guidage en translation verticale de l'extremite pivotante des branches par rapport audit support, et il se caracterise en ce qutil comporte pour chacun des fils un moyen de guidage apte a approcher ledit fil de la vegetation tout en l'amenant a une hauteur determinee qui The spreader device which is the subject of European patent application N 02 360058 is the only one capable of making it possible to perform a mechanical trellising, however there are currently no machines suitable for such an operation, and the present invention aims to remedy a this deficiency by proposing a device for lifting which, moreover, is of simple design and inexpensive. The device for the lifting of so-called lifting wires used in a trellising operation according to the invention is of the type comprising lifting means, means for tightening the wires and means for stapling them, it is carried by a towing machine capable of spanning the row of vegetation to be treated, it is intended to be used in plantations equipped with spreader devices of the type each comprising two branches secured to a spades by means of a support means, the free ends of which have each a means for retaining one of said lifting wires, and which is provided for able to take two positions, namely closed or the wind lifting wires close to one another, and open or said wind raising wires moving away from one the other, said branches each comprising a pivoting means associated with a stop means, allowing them to pass, after release of said raised threads, from the closed position to the position opened by gr avite, and from the open position to the closed position by the bringing together of said take-up wires, while said support means comprises means intended to allow guiding in vertical translation of the pivoting end of the branches relative to said support, and it characterized in that it comprises, for each of the wires, a guide means capable of approaching said wire of the vegetation while bringing it to a determined height which

correspond a la hauteur d'agrafage.corresponds to the stapling height.

Selon une autre caracteristique additionnelle du dispositif selon l' invention, les moyens de guidage vent decales l'un par rapport a l'autre, dans le sens longitudinal du rang de vegetation a traiter. Selon une autre caracteristique additionnelle du dispositif selon l' invention, chacun des moyens de guidage comporte deux parties superposees separees par une gorge peripherique et qui comportent chacune des moyens apses a amener le fil releveur dans According to another additional characteristic of the device according to the invention, the wind guiding means offset relative to each other, in the longitudinal direction of the row of vegetation to be treated. According to another additional characteristic of the device according to the invention, each of the guide means comprises two superimposed parts separated by a peripheral groove and which each comprise means capable of bringing the take-up wire into
