Abstract
Description
L'invention concerne le domaine de la mytiliculture et plusThe invention relates to the field of mussel culture and more
précisément les supports destinés à l'accrochage des moules dans les moulières. Traditionnellement, ces supports comportent des pieux réalisés à partir de troncs de chênes, plantés dans le fond des moulières. precisely the supports intended for hanging the molds in the molds. Traditionally, these supports include stakes made from oak trunks, planted in the bottom of the mussels.
Ces pieux sont reliés par des cordes supportant les naissains et trempant dans l'eau Lorsque les naissains ont atteint une certaine croissance, les cordes sont enroulées autour de la partie supérieure d'autres pieux en chêne qui présentent sur leur surface des aspérités 10 propices à l'accrochage des naissains. These stakes are connected by ropes supporting the spat and soaking in water. When the spat have reached a certain growth, the ropes are wound around the upper part of other oak stakes which have asperities on their surface suitable for spat hanging.
L'inconvénient du chêne est d'être putrescible; les pieux ont donc une durée de vie relativement courte et lorsqu'ils sont abîmés, il est nécessaire de les remplacer par de nouveaux pieux Ces opérations de rénovation des moulières sont coteuses et éprouvantes pour le 15 personnel. The disadvantage of oak is that it is putrescible; the piles therefore have a relatively short lifespan and when they are damaged, it is necessary to replace them with new piles These operations of renovation of the moldings are expensive and tiresome for the personnel.
Il a déjà été proposé de remplacer les pieux en bois par des pieux en matière plastique Mais ces essais n'ont pas donné satisfaction, car les naissains ne s'accrochent pas bien sur les surfaces des pieux en plastique. Le premier but de l'invention est de proposer un nouveau support pour moulière qui soit peu coteux et facile à mettre en oeuvre, qui ait une durée de vie supérieure à celle du pieu en bois et qui donne satisfaction en ce qui concerne l'accrochage des moules. It has already been proposed to replace wooden piles with plastic piles. However, these tests were not satisfactory, because the spat do not hang well on the surfaces of plastic piles. The first object of the invention is to propose a new support for a mold which is inexpensive and easy to implement, which has a longer lifespan than that of the wooden stake and which gives satisfaction with regard to attachment. mussels.
Le deuxième but de l'invention est de proposer un support dont 25 la hauteur est facilement réglable en fonction de la profondeur de la moulière. L'invention concerne donc un support utilisé en mytiliculture pour l'accrochage des moules comportant un pieu en matière plastique destiné à être planté dans le fond de la moulière. The second object of the invention is to provide a support whose height is easily adjustable as a function of the depth of the mold. The invention therefore relates to a support used in mussel farming for hanging molds comprising a plastic pile intended to be planted in the bottom of the mold.
Ce support est caractérisé par le fait qu'il comporte en outre un manchon creux entourant au moins partiellement la partie supérieure dudit pieu et susceptible de coulisser le long dudit pieu et des moyens pour fixer ledit manchon sur ledit pieu. This support is characterized in that it further comprises a hollow sleeve at least partially surrounding the upper part of said pile and capable of sliding along said pile and means for fixing said sleeve on said pile.
Ainsi, le pieu en matière plastique, qui a une durée de vie 35 nettement supérieure à celle d'un pieu en bois, ne réclame que très peu d'interventions. Le manchon peut être réalisé évidemment en plastique, mais selon une caractéristique avantageuse de l'invention, il présente une surface externe rugueuse, favorable à l'accrochage des naissains, et il est constitué d'un mélange de plastique et de matières végétales, notamment du bois. Thus, the plastic pile, which has a significantly longer lifespan than a wooden pile, requires very little intervention. The sleeve can obviously be made of plastic, but according to an advantageous characteristic of the invention, it has a rough external surface, favorable to the attachment of spat, and it consists of a mixture of plastic and plant materials, in particular wood.
Le manchon est réalisé de préférence par le procédé de moulage par extrusion, qui se prête à la fabrication d'un tube en continu, découpé ensuite à la longueur souhaitée, sans créer d'odeurs ni de risques pour l'evironnement. The sleeve is preferably produced by the extrusion molding process, which lends itself to the manufacture of a continuous tube, then cut to the desired length, without creating odors or risks to the environment.
Un autre avantage de l'invention est de permettre le recyclage des sciures et autres déchets végétaux. Another advantage of the invention is to allow the recycling of sawdust and other plant waste.
Pour diminuer le poids du pieu en plastique tout en lui assurant la rigidité nécessaire, le pieu est réalisé sous la forme d'un profilé ayant une section en croix. To reduce the weight of the plastic pile while ensuring the necessary rigidity, the pile is produced in the form of a profile having a cross section.
Ce profilé est également réalisé par extrusion d'un composé de plastique avec ou sans bois, végétaux, ou toutes autres matières naturelles et recyclables Ce profilé est découpé selon la longueur souhaitée, et l'une des extrémités du pieu est rendue pointue. This profile is also produced by extruding a plastic compound with or without wood, plants, or any other natural and recyclable material. This profile is cut to the desired length, and one of the ends of the pile is made sharp.
Les moyens de fixation du manchon sur le pied comportent une 20 cheville susceptible de traverser deux trous radicaux ménagés respectivement dans le manchon et le pieu. The means for fixing the sleeve to the foot include a pin capable of passing through two radical holes formed respectively in the sleeve and the pile.
De manière à pouvoir régler la hauteur du manchon par rapport au pieu, le manchon et/ou le pieu comportent une pluralité de trous radiaux susceptibles de recevoir une cheville. In order to be able to adjust the height of the sleeve relative to the pile, the sleeve and / or the pile have a plurality of radial holes capable of receiving a dowel.
D'autres avantages et caractéristiques de l'invention ressortiront à la lecture de la description suivante faite à titre d'exemple et en référence aux dessins annexés dans lesquels: la figure 1 montre en perspective un support selon l'invention planté dans une moulière, et la figure 2 est une coupe horizontale du support selon le plan II-II de la figure 1 qui montre les moyens de fixation du manchon sur le pieu. Le dessin montre un support i destiné à l'accrochage de moules d'élevage dans une moulière 2 Ce support i comporte un pieu 3 qui 35 présente, à son extrémité inférieure, une pointe 4 facilitant l'enfoncement du pieu 3 dans la vase 5 qui repose dans le fond de la moulière 2. Other advantages and characteristics of the invention will emerge on reading the following description given by way of example and with reference to the appended drawings in which: FIG. 1 shows in perspective a support according to the invention planted in a mold, and Figure 2 is a horizontal section of the support along the plane II-II of Figure 1 which shows the means of fixing the sleeve on the pile. The drawing shows a support i intended for the attachment of breeding molds to a mold 2 This support i comprises a stake 3 which has, at its lower end, a point 4 facilitating the insertion of the stake 3 into the mud 5 which rests in the bottom of the mold 2.
La partie supérieure du pieu 3, située au-dessus du fond de la moulière 2, loge dans l'espace intérieur 6 d'un manchon 7 creux cylindrique susceptible de coulisser le long du pieu 3. The upper part of the pile 3, located above the bottom of the mold 2, accommodates in the interior space 6 of a hollow cylindrical sleeve 7 capable of sliding along the pile 3.
Le manchon 7 est fixé sur le pieu 3 au moyen d'au moins une 5 cheville 8 qui traverse radialement le manchon 7 et le pieu 3 à travers deux trous radiaux 9, 10 traversant ménagés respectivement dans le manchon 7 et le pieu 3, comme cela est représenté sur la figure 2. The sleeve 7 is fixed to the pile 3 by means of at least one pin 8 which passes radially through the sleeve 7 and the pile 3 through two radial holes 9, 10 passing through formed respectively in the sleeve 7 and the pile 3, as this is shown in figure 2.
Pour permettre un réglage aisé de la hauteur du manchon 7 par rapport au niveau de l'eau de la moulière, le manchon 7 et le pieu 3 10 comportent une pluralité de trous 9 et 10 régulièrement espacés sur leur longueur. Le pieu 3 est réalisé en une matière plastique ou en mélange d'une matière plastique et de résidus de matières végétales, tels que des sciures ou des copeaux de bois, de préférence par le procédé d'extrusion. 15 Comme cela se voit clairement sur la figure 2, le pieu 3 a une section en croix et présente ainsi quatre nervures Le nombre de nervures peut évidemment être différent de quatre sans sortir du cadre de l'invention. Le manchon 7, quant à lui, est réalisé par extrusion d'un 20 mélange de matière plastique et matières végétales telles que sciures, copeaux Le diamètre intérieur du manchon 7 est légèrement supérieur au diamètre du cercle circonscrit du pieu 3 pour permettre un coulissement aisé du manchon 7 le long du pieu 3 Son épaisseur est fonction de la charge à supporter et de la rigidité souhaitée La surface externe présente 25 des rugosités qui facilitent l'accrochage des moules. To allow easy adjustment of the height of the sleeve 7 relative to the level of the mold water, the sleeve 7 and the pile 3 10 have a plurality of holes 9 and 10 regularly spaced along their length. The pile 3 is made of a plastic material or a mixture of a plastic material and plant material residues, such as sawdust or wood chips, preferably by the extrusion process. As can clearly be seen in FIG. 2, the pile 3 has a cross section and thus has four ribs. The number of ribs can obviously be different from four without departing from the scope of the invention. The sleeve 7, for its part, is produced by extrusion of a mixture of plastic and plant materials such as sawdust, chips. The internal diameter of the sleeve 7 is slightly greater than the diameter of the circumscribed circle of the pile 3 to allow easy sliding. of the sleeve 7 along the pile 3 Its thickness is a function of the load to be supported and the desired rigidity. The external surface has roughness which facilitates the attachment of the molds.
Le fait que le manchon incorpore du bois dans des proportions qui peuvent atteindre 80 % favorise également l'accrochage des naissains, et la formation d'aspérités. The fact that the sleeve incorporates wood in proportions that can reach 80% also promotes the hanging of spat, and the formation of roughness.
La cheville 8 peut être en matière plastique Elle peut également 30 être réalisée sous forme d'une pièce métallique enrobée de plastique pour la protéger de la corrosion. The pin 8 can be made of plastic. It can also be made in the form of a metal part coated with plastic to protect it from corrosion.
Du fait que le manchon 7 est essentiellement réalisé en bois, il est facile d'y planter des clous pour l'accrochage des cordes utilisées pour l'élevage des naissains. Because the sleeve 7 is essentially made of wood, it is easy to plant nails there for hanging the ropes used for spat breeding.
