Description

La présente invention est relative à un dispositif de support d'au moinsThe present invention relates to a support device of at least

une poche d'élevage des coquillages et notamment des huîtres. Il est d'usage courant, pour l'élevage notamment des huîtres, de mettre les jeunes huîtres dans des sacs ou des poches. Ces poches sont généralement posées à plat sur une table, reposant sur le fond marin et l'élevage des huîtres dure deux à trois ans. Mais, pour assurer la croissance de ces huîtres, il est impératif de tourner et retourner régulièrement ces poches avant que l'huître n'atteigne sa taille de commercialisation. Cette méthode d'élevage nécessite beaucoup de manutention et le travail des ostréiculteurs est particulièrement pénible et astreignant du fait du poids de chaque poche et du nombre important de poches à retourner régulièrement. L'invention a pour but d'éviter ces inconvénients en proposant un dispositif de support d'au moins une poche d'élevage des coquillages qui permet de retourner facilement et rapidement de grandes quantités de coquillages et ce par des moyens simples, fiables et peu coûteux. A cet effet, l'invention a pour objet un dispositif de support d'au moins une poche d'élevage des coquillages, caractérisé en ce qu'il comprend des moyens d'écartement des parois de la poche et un axe de rotation reliant lesdits moyens d'écartement et dont les extrémités situées en dehors de la poche, reposent sur un cadre pour permettre le retournement de ladite au moins poche. Le dispositif selon l'invention peut comporter une ou plusieurs des caractéristiques suivantes : - les rnoyens d'écartement comprennent au moins deux tiges en forme de S comportant deux branches d'extrémité en appui sur les parois de la poche et une branche centrale munie dudit axe de rotation, - les moyens d'écartement comprennent deux tiges en forme de S disposées sensiblement au niveau des bords latéraux de la poche et une tige en forme de S disposée sensiblement au milieu de ladite poche, et - le dispositif comprend des moyens de maintien de la poche sur le cadre dans une position sensiblement horizontale.  a pocket for breeding shells and in particular oysters. It is common practice, for breeding oysters in particular, to put young oysters in bags or pockets. These bags are usually laid flat on a table, resting on the seabed and oyster farming lasts two to three years. But, to ensure the growth of these oysters, it is imperative to turn and return these pockets regularly before the oyster reaches its marketing size. This method of farming requires a lot of handling and the work of oyster farmers is particularly painful and demanding because of the weight of each pocket and the large number of pockets to return regularly. The object of the invention is to avoid these drawbacks by proposing a support device for at least one shell-farming pouch which makes it possible to easily and quickly return large quantities of shells by simple, reliable means and little expensive. For this purpose, the subject of the invention is a device for supporting at least one shell-farming ladle, characterized in that it comprises means for spacing the walls of the ladle and an axis of rotation connecting said ladle. spacers and whose ends located outside the pocket, rest on a frame to allow the reversal of said at least pocket. The device according to the invention may comprise one or more of the following characteristics: the spacing means comprise at least two S-shaped rods comprising two end branches resting on the walls of the pocket and a central arm provided with said axis of rotation, the spacing means comprise two S-shaped rods disposed substantially at the lateral edges of the pocket and an S-shaped rod disposed substantially in the middle of said pocket, and the device comprises means for maintaining the pocket on the frame in a substantially horizontal position.

L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée à titre d'exemple et faite en référence aux dessins annexés, sur lesquels : La figure 1 est une vue schématique en perspective d'un dispositif de support conforme à l'invention, La figure 2 est une vue schématique en perspective des moyens d'écartement des parois d'une poche d'élevage de coquillages, et La figure 3 est une vue de côté d'une poche d'élevage de coquillages lors du retournement de cette poche.  The invention will be better understood on reading the description which will follow, given by way of example and with reference to the appended drawings, in which: FIG. 1 is a schematic perspective view of a support device according to FIG. FIG. 2 is a diagrammatic perspective view of the spacing means of the walls of a shell-farming pocket, and FIG. 3 is a side view of a shell-farming pocket during the flipping this pocket.

Sur la figure 1, on a représenté schématiquement une poche d'élevage de coquillages, et notamment d'huîtres, désignée dans son ensemble par la référence 1. De manière classique cette poche 1 est formée par un grillage comportant des mailles permettant la circulation de l'eau et ladite poche comporte deux parois 2 longitudinales et opposées. La poche 1 repose sur un dispositif de support qui comprend, d'une manière générale, des moyens 10 d'écartement des parois 2 de la poche 1 et un axe de rotation 11 reliant lesdits moyens d'écartement. Ainsi que montré sur les figures 1 et 2, les moyens 10 d'écartement des parois de la poche 2 comprennent au moins deux tiges 12 en forme de S comportant deux branches d'extrémité 12a sur lesquelles sont en appui les parois 2 de la poche 1 et un branche centrale 12b munie dudit axe de rotation 11. De préférence, les moyens 10 d'écartement comprennent deux tiges 12 en forme de S disposées sensiblement au niveau des bords latéraux de la poche 1 et une tige 12 en forme de S disposée sensiblement au milieu de ladite poche 1. Comme représenté à la figure 1, les deux extrémités 11 a de l'axe 11 situées en dehors de la poche 1 reposent sur un cadre 15 qui est en appui sur le fond marin de telle sorte que cette poche 1 soit placée au dessus de ce fond marin pour permettre la circulation de l'eau autour de cette poche 1. Le cadre 15 peut, bien évidemment, comporter plusieurs emplacements placés les uns à côté des autres et comportant chacun une poche 1. La poche 1 est fermée par des moyens appropriés de type connu, qui relient les extrémités de ladite poche entre elles.  FIG. 1 diagrammatically shows a ladle for culturing shells, and in particular oysters, generally designated by the reference numeral 1. In a conventional manner, this pouch 1 is formed by a mesh comprising meshes allowing the circulation of the water and said pocket has two longitudinal walls 2 and opposite. The pocket 1 rests on a support device which generally comprises means 10 for spacing the walls 2 from the pocket 1 and an axis of rotation 11 connecting said spacing means. As shown in FIGS. 1 and 2, the means 10 for separating the walls of the bag 2 comprise at least two S-shaped rods 12 having two end branches 12a on which the walls 2 of the bag are resting. 1 and a central branch 12b provided with said axis of rotation 11. Preferably, the spacing means 10 comprise two S-shaped rods 12 disposed substantially at the lateral edges of the bag 1 and an S-shaped rod 12 arranged substantially in the middle of said pocket 1. As shown in Figure 1, the two ends 11a of the axis 11 located outside the pocket 1 rest on a frame 15 which is supported on the seabed so that this 1 pocket is placed above this seabed to allow the flow of water around this pocket 1. The frame 15 may, of course, have several locations placed next to each other and each having a pocket 1. The pocket 1 is closed e by suitable means of known type, which connect the ends of said pocket between them.

Etant donné que les extrémités 11 a de l'axe de rotation Il sont en appui sur le cadre 15, il suffit à l'ostréiculteur de faire pivoter cette poche autour de cet axe de rotation 11 pour la retourner, et cela sans la soulever ce qui diminue les opérations de manutention et procure un gain de temps. La poche 1 est maintenue dans une position sensiblement horizon-tale, comme montrée à la figure 1, par des moyens 20 de maintien qui sont constitués par exemple par des sangles ou par tout autre dispositif approprié. Les tiges 12 placées entre les parois 2 de la poche 1 permettent de maintenir la poche 1 gonflée par écartement de ses parois 2, ce qui assure une meilleure circulation de l'eau dans la poche 1 et une meilleure aération des huîtres. Selon un variante, les axes de rotation 11 de plusieurs poches 1 placées les unes à côté des autres sur le cadre 15 peuvent être reliés entre eux, ce qui permet de retourner simultanément plusieurs poches.  Since the ends 11a of the axis of rotation Il are resting on the frame 15, it is sufficient for the oyster farmer to rotate this pocket around this axis of rotation 11 to return it, without lifting it. which reduces handling operations and saves time. The pocket 1 is held in a substantially horizontal position, as shown in FIG. 1, by holding means 20 which consist for example of straps or by any other appropriate device. The rods 12 placed between the walls 2 of the bag 1 make it possible to keep the bag 1 inflated by spacing its walls 2, which ensures better circulation of water in the bag 1 and better aeration of the oysters. Alternatively, the axes of rotation 11 of several pockets 1 placed next to each other on the frame 15 may be interconnected, allowing to return multiple pockets simultaneously.

Il apparaît clairement à partir de cette description, que la manipulation des huîtres est grandement facilitée et que le retournement des poches de coquillages s'effectue sans effort et sans avoir à soulever ces poches. Le dispositif de support selon l'invention apporte également une amélioration à l'élevage des coquillages, et notamment des huîtres, du fait que ces coquillages sont mieux oxygénés et leur qualité est ainsi accrue.  It is clear from this description that the handling of oysters is greatly facilitated and that the turning of the shell bags is effortless and without lifting these pockets. The support device according to the invention also provides an improvement in the rearing of shellfish, and in particular oysters, because these shells are better oxygenated and their quality is thus increased.
