Description

DISPOSITIF D'ECLAIRCISSAGE D'ARBRE FRUITIERFRUIT TREATING LIGHTENING DEVICE
La présente invention entre dans le domaine agricole, dans la culture d'arbre fruitier.The present invention is in the agricultural field, in the fruit tree culture.
L'invention concerne plus particulièrement le contrôle de la floribondité d' un arbre fruitier .The invention relates more particularly to the control of the floribundity of a fruit tree.
Pour ce faire, elle concerne un dispositif d'enlèvement de fleurs d' un arbre fruitier .To do this, it relates to a device for removing flowers from a fruit tree.
Un tel dispositif trouvera une application particulière, mais non limitative, dans l'enlèvement de fleurs de pêcher ou d' abricotier .Such a device will find a particular application, but not limiting, in the removal of peach or apricot blossom.
De manière connue , il convient de diminuer le nombre de fleurs présentes sur un arbre fruitier, notamment pour améliorer la qualité des fruits obtenus. Pour ce faire, il est nécessaire de réaliser un éclaircissage des fleurs qui ont éclos sur les branches et rameaux dudit arbre fruitier.In known manner, it is necessary to reduce the number of flowers present on a fruit tree, in particular to improve the quality of the fruits obtained. To do this, it is necessary to thin the flowers that hatched on the branches and branches of the fruit tree.
Actuellement, cette opération consiste à retirer à la main les fleurs, notamment par frottement sur le rameau des doigts protégés par un gant. Cette opération manuelle est longue et fastidieuse, impliquant un coût en main d' œuvre élevé. On estime ce coût horaire de l'ordre de 100 à 400 heures par hectare d' arbres fruitiers , suivant les variétés et les années . De plus , les branches hautes restent difficiles d' accès .Currently, this operation is to remove the flowers by hand, including by rubbing on the twig of fingers protected by a glove. This manual operation is long and tedious, involving a high labor cost. This hourly cost is estimated at 100 to 400 hours per hectare of fruit trees, depending on the variety and the year. In addition, the high branches remain difficult to access.
Il a donc été imaginé des dispositifs pour enlever les fleurs des branches, notamment par arrachage. Le plus simple d'entre eux consiste en une pince agissant par raclement sur les deux côtés d'un rameau, en symétrie de part et d'autre de ce dernier. Un inconvénient majeur réside dans le fait que les fleurs arrachées restent emprisonnées dans l'étau que forme cette pince, de sorte qu'elles créent un bourrage rendant plus difficile l'opération et enlevant les fleurs suivantes.It has been imagined devices to remove the flowers branches, including tearing. The simplest of them consists of a pliers acting by scraping on both sides of a branch, in symmetry on both sides of the latter. A major drawback lies in the fact that the flowers torn off remain trapped in the vice that forms this clamp, so that they create a jam making it more difficult the operation and removing the following flowers.
De plus, le maintien de la branche lors de cette opération n'est pas assuré. De tels dispositifs ne tiennent pas compte de l'épaisseur décroissante des rameaux. Enfin, l'accès aux branches hautes pose toujours problème.In addition, the maintenance of the branch during this operation is not assured. Such devices do not take into account the decreasing thickness of the branches. Finally, access to high branches is still a problem.
D'autres outils agricoles et de jardinier ont tenté de pallier ses inconvénients sans pour autant apporter une solution satisfaisante .Other agricultural and gardening tools have tried to overcome its disadvantages without providing a satisfactory solution.
Enfin, les méthodes employées actuellement sont efficaces qu'à un certain stade de maturité, par exemple pour des fleurs à pleine maturité ou pour les petits fruits , limitant la durée pendant laquelle peut être faite cette étape d'éclaircissage.Finally, the methods currently used are effective at a certain stage of maturity, for example for fully mature flowers or for small fruits, limiting the duration during which this thinning step can be made.
L'invention a pour but de pallier les inconvénients de l'état de la technique en proposant un dispositif d' enlèvement de fleurs d' un arbre fruitier par arrachement depuis leur branche .The invention aims to overcome the disadvantages of the state of the art by providing a device for removing flowers from a fruit tree by tearing from their branch.
Un tel dispositif comprend des moyens de préhension sous forme d'un manche à l'extrémité duquel sont montés solidaires des moyens d' arrachage desdites fleurs . Ce dispositif se veut à même d'enlever aisément et sans bourrage une partie des fleurs poussant sur une branche .Such a device comprises gripping means in the form of a handle at the end of which are mounted integral means for tearing said flowers. This device is able to remove easily and without jamding part of the flowers growing on a branch.
Pour ce faire, il se caractérise par le fait que lesdits moyens d'arrachage comprennent au moins deux éléments en appui par pincement asymétrique de part et d' autre de ladite branche .To do this, it is characterized in that said tearing means comprise at least two elements bearing by asymmetric clamping on either side of said branch.
Le dispositif d'enlèvement selon l'invention permet d'arracher les fleurs situées de part et d'autre de la branche, tout en conservant les fleurs sur les côtés, ou inversement.The removal device according to the invention allows to tear the flowers located on either side of the branch, while maintaining the flowers on the sides, or vice versa.
De plus, il s'adapte à tout type d'arbre fruitier peu importe la section et la forme des branches ou rameaux à éclaircir. Par ailleurs, ces derniers sont protégés et ne subissent aucune détérioration .Plus, it adapts to any type of fruit tree no matter the section and shape of branches or twigs to thin. In addition, they are protected and do not suffer any deterioration.
Du fait de sa forme, un tel dispositif empêche aussi le bourrage des fleurs arrachées au travers de leur évacuation. Il permet d'accéder aux branches hautes facilement, notamment sans avoir recours à une échelle ou analogue .Because of its shape, such a device also prevents the jamming of flowers torn through their evacuation. It allows access to the high branches easily, especially without using a ladder or the like.
Avantageusement, sa simplicité autorise une fabrication rapide et peu coûteuse. De plus, il permet d'améliorer le rendement horaire et de diminuer les coûts d'éclaircissage d'un verger.Advantageously, its simplicity allows quick and inexpensive manufacturing. In addition, it improves the hourly yield and reduces the costs of thinning an orchard.
D'autres caractéristiques et avantages de l'invention ressortiront de la description détaillée qui va suivre des modes de réalisation non limitatifs de l'invention, en référence à la figure annexée montrant un mode particulier de réalisation du dispositif selon l'invention au cours de l'opération d'arrachage des fleurs présentes sur une branche.Other features and advantages of the invention will emerge from the following detailed description of the non-limiting embodiments of the invention, with reference to the appended figure showing a particular embodiment of the device according to the invention in the course of the operation of tearing flowers present on a branch.
La présente invention concerne un dispositif 1 d'enlèvement de fleurs 2 d'un arbre fruitier par arrachement depuis leur branche 3.The present invention relates to a device 1 for removing flowers 2 from a fruit tree by tearing from their branch 3.
Un tel dispositif 1 comprend des moyens de préhension sous forme d' un manche 4. Ce dernier peut être recouvert par une poignée ou un revêtement améliorant la préhension par un utilisateur. Cette poignée peut être de toute forme et conformée ergonomiquement pour faciliter la prise en main ainsi que le maniement du dispositif 1.Such a device 1 comprises gripping means in the form of a handle 4. The latter can be covered by a handle or a coating improving the grip by a user. This handle can be of any shape and shaped ergonomically to facilitate handling and the handling of the device 1.
On notera que le manche peut être prévu de différentes longueurs ou de longueur variable , par exemple au travers de sections télescopiques .Note that the handle can be provided of different lengths or variable length, for example through telescopic sections.
A une des extrémités du manche, sont montés solidaires des moyens 5 d'arrachage desdites fleurs 2. Lesdits moyens d'arrachage 5 sont avantageusement conformés de manière à venir en appui contre ladite branche 3. Plus particulièrement, ils comprennent au moins deux éléments venant en appui par pincement de part et d' autre de la branche 3.At one of the ends of the handle, are mounted solidarity means 5 for tearing off said flowers 2. Said tearing means 5 are advantageously shaped so as to bear against said branch 3. More particularly, they comprise at least two elements bearing on each other by pinching on either side of branch 3.
Dès lors, le glissement des moyens 5 le long de la branche 3 enlève les fleurs 2 sur toute la périphérie de la branche où lesdits moyens 5 sont en appui . Les tiges des fleurs 2 étant flexibles mais peu résistantes, le simple coulissement au contact du de l'écorce de la branche permet leur arrachement.Therefore, the sliding of the means 5 along the branch 3 removes the flowers 2 over the entire periphery of the branch where said means 5 are supported. The stems of the flowers 2 being flexible but not strong, the simple sliding in contact with the bark of the branch allows their tearing.
Par contre, les fleurs 2, ayant poussé au niveau de la branche 3 où les moyens 5 ne viennent pas en contact, restent intactes. Par conséquent, l'éclaircissement a lieu uniquement sur une partie du pourtour de la branche 3 tout en conservant des fleurs 2 sur le reste de la branche 3.On the other hand, the flowers 2, having grown at the level of the branch 3 where the means 5 do not come into contact, remain intact. Therefore, the lightening takes place only on part of the perimeter of the branch 3 while retaining flowers 2 on the rest of the branch 3.
En fonction du placement des éléments en appui sur la branche 3, les fleurs 2 peuvent être arrachées au-dessus ou en-dessous et conservées sur les côtés , ou bien arrachées sur les côtés et conservées en-dessus et en-dessous .Depending on the placement of the support elements on the branch 3, the flowers 2 can be pulled above or below and kept on the sides, or ripped on the sides and kept above and below.
De plus, cet effet de pince desdits deux éléments permet de maintenir la branche 3 ou le rameau lorsque le dispositif 1 coulisse le long de ce dernier. La variation de la force d'appui permet de s'adapter en fonction de la souplesse de la branche. A titre d'exemple, à sa base, la branche étant plus rigide, il n'est pas nécessaire de maintenir un appui de manière forte alors qu'afin d'autoriser le coulissement au bout de la branche, il est alors nécessaire de l'enserrer davantage, appliquant une force plus importante .In addition, this clamping effect of said two elements makes it possible to maintain the branch 3 or the branch when the device 1 slides along the latter. The variation of the support force makes it possible to adapt according to the flexibility of the branch. By way of example, at its base, the branch being more rigid, it is not necessary to maintain a strong support while in order to allow sliding at the end of the branch, it is then necessary to to grip more, applying a greater force.
En appui, les deux éléments appuient asymétriquement : il ne se retrouvent pas en superposition de part et d' autre de la branche . En d' autres termes , en un point donné de ladite branche 3, les éléments ne sont pas symétriques l'un par rapport à l'autre selon l'axe longitudinal passant par la branche 3. Ce décalage permet l'extraction des fleurs arrachées sans aucun risque de bourrage . Une telle asymétrie améliore aussi le maintien de la branche 3.In support, the two elements support asymmetrically: they are not found in superposition on both sides of the branch. In other words, at a given point in the said branch 3, the elements are not symmetrical relative to each other along the longitudinal axis passing through the branch 3. This offset allows the extraction of flowers torn without any risk of jamming. Such asymmetry also improves the maintenance of branch 3.
Cette caractéristique est améliorée par le fait que les moyens d'arrachage 5 sont conformés de manière à entourer la branche 3 , en appui au niveau des deux éléments , mais en ménageant un espace de chaque côté de ceux-ci. Cet espace permet de ne pas arracher les fleurs 2 situées à ce niveau mais aussi permet aux fleurs arrachées de s'échapper, ainsi que les feuilles, sans bourrage possible.This feature is improved by the fact that the tearing means 5 are shaped so as to surround the branch 3, supported at the level of the two elements, but leaving a space on each side thereof. This space makes it possible not to tear the flowers 2 located at this level but also allows the torn flowers to escape, as well as the leaves, without jamming possible.
Selon le mode préférentiel de réalisation, lesdits moyens d'arrachage 5 sont constitués par au moins une tige 6 recourbée. Comme évoqué précédemment, cette courbure permet de ménager lesdits espaces pour l'extraction des fleurs 2 sur une portion de la périphérie de la branche 3 lors du passage du dispositif 1.According to the preferred embodiment, said tearing means 5 are constituted by at least one curved rod 6. As mentioned above, this curvature makes it possible to arrange said spaces for the extraction of the flowers 2 on a portion of the periphery of the branch 3 during the passage of the device 1.
Plus particulièrement, cette tige 6 peut présenter une forme en U, formant une anse. Un des côtés 7 de ce U est alors relié audit manche 4. L'autre extrémité 8 peut être laissée libre. Ladite extrémité 8 peut avantageusement mais non limitativement s'étendre parallèlement audit côté 7. Ledit côté 7 et ladite extrémité 8 forment alors lesdits deux éléments .More particularly, this rod 6 may have a U-shape, forming a loop. One of the sides 7 of this U is then connected to said handle 4. The other end 8 can be left free. Said end 8 can advantageously but not limitatively extend parallel to said side 7. Said side 7 and said end 8 then form said two elements.
Ladite courbure de la tige 6 peut être définie en fonction du type d'arbre fruitier, notamment en fonction de la section ou de la forme de ses branches 3 ainsi que de la taille de ses fleurs 2.Said curvature of the stem 6 can be defined according to the type of fruit tree, in particular according to the section or the shape of its branches 3 as well as the size of its flowers 2.
De plus, selon un mode particulier de réalisation, ladite tige 6 peut être constituée d' un matériau souple ou flexible . Plus particulièrement, ce matériau peut aussi être à mémoire de forme , de manière à augmenter ou diminuer le rayon de courbure de ladite tige 6, notamment par torsion manuelle ou mécanique.In addition, according to a particular embodiment, said rod 6 may be made of a flexible or flexible material. More particularly, this material can also be memory shape, so as to increase or decrease the radius of curvature of said rod 6, in particular by manual or mechanical torsion.
On notera que la courbure peut être de toute dimension supérieure à la plus grande section des branches 3 de l'arbre à éclaircir. L'écartement entre les deux éléments peut être plus ou moins important en fonction du type d'arbre à éclaircir.Note that the curvature may be of any size greater than the largest section of branches 3 of the tree to be lightened. The spacing between the two elements may be more or less important depending on the type of tree to be lightened.
A ce titre, lors de l'éclaircissage, l'utilisateur tient le dispositif 1 par les moyens de préhension. Il passe les moyens d'arrachage 5 autour de la branche 3 choisie puis, par simple rotation du poignet, il met en contact sur la branche 3, de part et d'autre, le côté 7 et l'extrémité 8. Dans cette position, le glissement assure donc de suivre la forme de la branche 3, tout en épousant ses contours. L'appui en pincement permet de maintenir la branche tout en coulissant le long de cette dernière , arrachant les fleurs 2 au passage .As such, during thinning, the user holds the device 1 by the gripping means. It passes the tearing means 5 around the selected branch 3 and then, by simple rotation of the wrist, it puts in contact on the branch 3, on either side, the side 7 and the end 8. In this position , the slip ensures to follow the shape of the branch 3, while marrying its contours. The pinch support keeps the branch while sliding along the latter, tearing the flowers 2 in passing.
Le blocage sur un nœud éventuel peut être facilement évité en desserrant la prise en appui sur la branche, par simple rotation comme précédemment mentionnée . De plus , la traction ainsi exercée peut être facilement contrôlée , évitant d' abimer la branche 3 et l'arbre. La gestion de la force de pincement permet aussi de s'adapter à la section et la rigidité de la branche 3 tout au long de cette dernière .The blocking on a possible node can be easily avoided by loosening the socket bearing on the branch, by simple rotation as previously mentioned. In addition, the traction thus exerted can be easily controlled, avoiding damaging the branch 3 and the shaft. The management of the pinching force also makes it possible to adapt to the section and the rigidity of the branch 3 throughout the latter.
Avantageusement, selon un mode particulier de réalisation, non représenté , ladite tige 6 comprend des moyens de frottement de ladite branche 3 sous forme de poils. Lesdits poils s'étendent sur toute ou partie de ladite tige 6. Plus particulièrement, ils sont montés solidaires de ladite tige 6 sur toute ou partie de la courbure, de son côté 7 et/ou de l'extrémité libre 8. Ces poils peuvent être disposés intérieurement, extérieurement ou sur toute ou partie de la périphérie de ladite tige .Advantageously, according to a particular embodiment, not shown, said rod 6 comprises friction means of said branch 3 in the form of bristles. Said hairs extend over all or part of said rod 6. More particularly, they are mounted integral with said rod 6 on all or part of the curvature, on its side 7 and / or the free end 8. These hairs can be disposed internally, externally or over all or part of the periphery of said rod.
Ces poils forment une brosse plus ou moins dense en fonction du nombre de poils et de leur disposition sur la tige 6. Préférentiellement, ils peuvent être rigides. Ils peuvent aussi être prévus en matériau semi-rigides, souples ou élastiques et prévus de toute longueur possible.These hairs form a more or less dense brush depending on the number of hairs and their arrangement on the rod 6. Preferably, they can be rigid. They can also be provided in semi-rigid, flexible or elastic material and provided of any possible length.
Une telle brosse facilite l'utilisation du dispositif 1 sur des branches 3 et rameaux tortueux ou noueux, comme c'est le cas de l'abricotier. Cette brosse permet de ne pas blesser le rameau, voire les jeunes fruits si l'intervention d' éclaircissage est réalisée à ce stade .Such a brush facilitates the use of the device 1 on branches 3 and twisted branches or knotty, as is the case of apricot. This brush makes it possible not to injure the branch, or even the young fruits if thinning is performed at this stage.
L'invention facilite grandement l' éclaircissage d'arbre fruitier au travers d'un dispositif 1 simple et peu coûteux. Facile et rapide d'utilisation, il économise un grand nombre d'heures de main d'œuvre et permet d'enlever 30 à 70% des fleurs . De plus , il peut être utilisé durant une période plus longue, n'ayant aucune restriction quand à la maturité des fleurs ou des petits fruits à arracher.The invention greatly facilitates the thinning of fruit trees through a simple and inexpensive device 1. Easy and fast to use, it saves a lot of manpower and can remove 30 to 70% of the flowers. In addition, it can be used for a longer period, with no restrictions when the flowers or berries ripen.
Bien entendu, l'invention n'est pas limitée aux exemples illustrés et décrits précédemment qui peuvent présenter des variantes et modifications sans pour autant sortir du cadre de 1 ' invention . Of course, the invention is not limited to the examples illustrated and described above which may have variants and modifications without departing from the scope of the invention.
