Description

Système de distribution d'aliments pour animaux, notamment pour volailles. Animal feed distribution system, especially for poultry.
La présente invention concerne un système de distribution d'aliments pour animaux, notamment pour volailles.The present invention relates to a system for distributing animal feed, in particular for poultry.
On connaît déjà de tels systèmes et on pourra notamment se reporter aux documents US-A-5 474 027 et EP-A-437 357. Ces systèmes comprennent essentiellement un convoyeur linéaire qui, au moyen d'une trémie, est alimenté à son extrémité amont en aliments à distribuer.Such systems are already known and reference may in particular be made to documents US-A-5,474,027 and EP-A-437,357. These systems essentially comprise a linear conveyor which, by means of a hopper, is fed at its end upstream in food to be distributed.
En particulier, dans le document US-A-5474 027, le long du convoyeur linéaire sont installées, régulièrement espacées les unes des autres, des stations individuelles de distribution d'aliments. Ainsi, selon ce document, le convoyeur déverse les aliments qu'il entraîne dans chacune des stations de distribution individuelles où les animaux peuvent alors se nourrir.In particular, in document US-A-5474 027, along the linear conveyor are installed, regularly spaced from each other, individual food distribution stations. Thus, according to this document, the conveyor pours the food which it carries into each of the individual distribution stations where the animals can then feed.
Dans le document EP-A-437 357, le convoyeur linéaire est lui ouvert sur une longue auge disposée sous lui sur toute sa longueur. Les aliments qu'il transporte peuvent être déversés dans l'auge et ainsi être distribués aux animaux qui se trouvent le long de l'auge.In document EP-A-437 357, the linear conveyor is open to it on a long trough disposed under it over its entire length. The food it carries can be poured into the trough and thus be distributed to the animals that are along the trough.
On notera que les convoyeurs qui sont décrits dans les documents précédemment cités sont constitués de tubes dans lesquels tournent des vis d'Archimède. L'inconvénient des systèmes précédemment décrits réside dans le fait que, lorsque le convoyeur est mis en marche, les aliments sont d'abord distribués dans les stations individuelles proches de l'extrémité du convoyeur où se trouve la trémie d'alimentation ou dans la partie de l'auge qui se trouve près de cette extrémité. En fait, ces systèmes sont plutôt prévus pour une distribution continue d'aliments, ce qui pose alors le problème des doses qui sont données aux animaux et qui ne peuvent être suffisamment contrôlées.It will be noted that the conveyors which are described in the documents cited above consist of tubes in which Archimedes screws rotate. The disadvantage of the systems described above resides in the fact that, when the conveyor is started, the feeds are first distributed in the individual stations close to the end of the conveyor where the feed hopper is located or in the part of the trough which is near this end. In fact, these systems are rather intended for a continuous distribution of food, which then poses the problem of the doses which are given to animals and which cannot be sufficiently controlled.
En utilisation discontinue, à chaque démarrage du convoyeur, les animaux s'agglutinent dans la zone qui est d'abord distribuée et se battent pour pouvoir y accéder. Il en résulte des bagarres d'animaux particulièrement préjudiciables. De plus, ce sont généralement les animaux les plus forts qui réussissent alors à s'alimenter au détriment des animaux les plus faibles, aggravant, à chaque distribution, le déséquilibre de leur pondération .In discontinuous use, each time the conveyor starts, the animals congregate in the area which is first distributed and fight to gain access. This results in particularly harmful animal fights. In addition, it is generally the strongest animals which then succeed in feeding at the expense of the weakest animals, aggravating, with each distribution, the imbalance in their weighting.
On connaît également, par le document DE-A-1 163 075, un système de distribution d'aliments pour animaux, notamment des porcs, qui comprend des moyens de stockage, constitués d'un tube qui loge une vis d'Archimède, qui peuvent prendre une première position où ils stockent les aliments transportés par ladite vis d'Archimède et une deuxième position, dite position escamotée, où ils déversent l'ensemble de leur contenu dans ladite ou chaque auge, et une unité de pilotage prévue pour commander lesdits moyens de stockage de manière que, pendant une première phase, ils se trouvent dans ladite première position et stockent ainsi les aliments transportés par ledit convoyeur et que, pendant une seconde phase, ils soient escamotés et déversent ainsi l'ensemble de leur contenu dans ladite ou chaque auge.Document DE-A-1 163 075 also discloses a system for distributing animal feed, in particular pigs, which comprises storage means, consisting of a tube which houses an Archimedes screw, which can take a first position where they store the food transported by said Archimedes screw and a second position, called retracted position, where they pour all of their contents into said or each trough, and a control unit provided for controlling said storage means so that, during a first phase, they are in said first position and thus store the food transported by said conveyor and that, during a second phase, they are retracted and thus pour all of their content into said or each trough.
Ladite unité de pilotage comprend un dispositif de détection placé à l'extrémité dudit convoyeur opposée à l'extrémité d'alimentation dudit convoyeur et permettant de détecter que la totalité de la vis d'Archimède est pleine d'aliment. Cette unité de pilotage, après détection par ledit dispositif passe de ladite première phase à ladite seconde phase.Said control unit comprises a detection device placed at the end of said conveyor opposite to the feed end of said conveyor and making it possible to detect that the whole of the Archimedes screw is full of food. This control unit, after detection by said device passes from said first phase to said second phase.
Le principal inconvénient du système qui est décrit dans ce document est qu'il n'est pas prévu pour distribuer de faibles quantités d'aliment, notamment du fait qu'il ne s'adresse pas à des volailles comme cela est le cas de la présente invention, mais à des porcs. Un tel système est donc particulièrement mal adapté à ce type d'animal. Le but de l'invention est de prévoir un système de distribution d'aliments pour animaux, notamment de volailles, du type de celui qui est décrit ci-dessus, mais qui n'en présente pas les inconvénients précédemment donnés.The main drawback of the system which is described in this document is that it is not intended to distribute small quantities of feed, in particular because it is not intended for poultry as is the case of the present invention, but to pigs. Such a system is therefore particularly ill-suited to this type of animal. The object of the invention is to provide a system for distributing animal feed, in particular poultry, of the type described above, but which does not have the disadvantages previously given.
A cet effet, un système de distribution d'aliments pour animaux, notamment de volailles selon la présente invention est caractérisé en ce que la vis d'Archimède est une vis creuse constituée d'un fil relativement épais enroulée hélicoïdalement.To this end, a system for distributing animal feed, in particular poultry according to the present invention is characterized in that the Archimedes screw is a hollow screw made up of a relatively thick wire wound helically.
Cette vis est logée dans un tube qui, généralement, constitue des moyens de stockage lesquels sont constitués de moyens d'obturation prévus pour obturer des lumières prévues dans la partie inférieure dudit convoyeur, les aliments étant alors stockés dans ledit convoyeur.This screw is housed in a tube which, generally, constitutes storage means which consist of shutter means provided for closing lights provided in the lower part of said conveyor, the food then being stored in said conveyor.
De plus, entre les lumières dont sont pourvus lesdits moyens de stockage, sont prévus des interstices dont la largeur est du même ordre de grandeur, par exemple identique, à la largeur desdites lumières.In addition, between the openings with which said storage means are provided, interstices are provided whose width is of the same order of magnitude, for example identical, to the width of said openings.
Selon une variante de réalisation de la présente invention, lesdits moyens de stockage sont constitués de moyens de réserve prévus sous des lumières prévues dans la partie inférieure dudit convoyeur de manière à pouvoir recueillir les aliments déversés par ledit convoyeur et les stocker.According to an alternative embodiment of the present invention, said storage means consist of reserve means provided under lights provided in the lower part of said conveyor so as to be able to collect the food spilled by said conveyor and store it.
Selon une autre variante de réalisation de la présente invention, lesdits moyens de stockage sont constitués de moyens d'obturation et de réserve prévus sous des lumières prévues dans la partie inférieure dudit convoyeur de manière, soit à pouvoir obturer lesdites lumières, soit à pouvoir recueillir les aliments déversés par ledit convoyeur et les stocker, soit à être escamotés.According to another alternative embodiment of the present invention, said storage means consist of shutter and reserve means provided under lights provided in the lower part of said conveyor so as either to be able to close said lights, or to be able to collect the food spilled by said conveyor and store it, or to be retracted.
Selon une autre caractéristique de la présente invention, lesdits moyens de stockage sont constitués d'au moins un volet monté de manière à pouvoir coulisser longitudinalement sur ledit convoyeur. Lesdits moyens de stockage peuvent également être constitués d'au moins un volet monté de manière à pouvoir coulisser axialement sur ledit convoyeur.According to another characteristic of the present invention, said storage means consist of at least one flap mounted so as to be able to slide longitudinally on said conveyor. Said storage means can also consist of at least one flap mounted so as to be able to slide axially on said conveyor.
Selon une autre caractéristique alternative de la précédente, lesdits moyens de stockage sont constitués d'au moins un volet prévu pour pivoter autour d'un axe de pivotement parallèle à l'axe longitudinal dudit convoyeur, ledit axe trouvant sur un des côtés dudit volet. Avantageusement, ledit ou chaque volet présente une section en forme de N dont la pointe est tronquée, ledit volet étant prévu pour inclure ledit convoyeur. Ledit ou chaque volet est par exemple relié à un vérin de commande au moyen d'un câble dont la longueur peut être ajustée.According to another alternative characteristic of the previous one, said storage means consist of at least one flap designed to pivot around a pivot axis parallel to the longitudinal axis of said conveyor, said axis being on one of the sides of said flap. Advantageously, said or each flap has an N-shaped section whose tip is truncated, said flap being provided to include said conveyor. Said or each flap is for example connected to a control jack by means of a cable whose length can be adjusted.
Selon une autre caractéristique de la présente invention, ledit convoyeur est alimenté à son extrémité amont par l'intermédiaire d'un volet de dosage. Selon une autre caractéristique de l'invention, ledit convoyeur est logé dans un tube comprenant une partie inférieure et une partie supérieure, ladite partie supérieure étant démontable de manière à pouvoir accéder à l'élément d'entraînement dudit convoyeur.According to another characteristic of the present invention, said conveyor is supplied at its upstream end via a metering flap. According to another characteristic of the invention, said conveyor is housed in a tube comprising a lower part and an upper part, said upper part being removable so as to be able to access the drive element of said conveyor.
Enfin, la présente invention concerne une installation de distribution qui comporte une pluralité de systèmes de distribution selon une des revendications précédentes.Finally, the present invention relates to a distribution installation which comprises a plurality of distribution systems according to one of the preceding claims.
Les caractéristiques de l'invention mentionnées ci-dessus, ainsi que d'autres, apparaîtront plus clairement à la lecture de la description suivante d'un exemple de réalisation, ladite description étant faite en relation avec les dessins joints, parmi lesquels :The characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the following description of an exemplary embodiment, said description being made in relation to the accompanying drawings, among which:
La Fig. 1 est une vue schématique d'une installation de distribution d'aliments pour animaux selon la présente invention,Fig. 1 is a schematic view of an animal feed distribution installation according to the present invention,
Les Figs. 2a à 2c sont respectivement des vues en coupe selon le plan II-II de la Fig. 1 d'une installation de distribution d'aliments selon la présente invention, et La Fig. 3 est une vue en perspective d'une partie du tube logeant un convoyeur d'une installation de distribution d'aliments selon la présente invention.Figs. 2a to 2c are respectively sectional views along the plane II-II of FIG. 1 of a food distribution installation according to the present invention, and FIG. 3 is a perspective view of part of the tube housing a conveyor of a food distribution installation according to the present invention.
L'installation de distribution d'aliments pour animaux représentée à la Fig. 1 comprend un convoyeur linéaire 10 qui est alimenté à son extrémité amont en aliments à distribuer, par exemple stockés dans une trémie 11. Le convoyeur linéaire 10 est par exemple constitué d'un tube logeant une vis d'Archimède qui est entraînée en rotation au moyen d'un moteur 12 avantageusement électrique. Afin de pouvoir alimenter le tube du convoyeur 10 avec des quantités d'aliment relativement faible, la vis d'Archimède 11 est, selon la présente invention, une vis creuse, par exemple constituée d'un fil relativement épais enroulée hélicoïdalement. La hauteur d'aliment dans le tube du convoyeur 10 ne peut ainsi excéder l'épaisseur du fil.The animal feed distribution installation shown in FIG. 1 comprises a linear conveyor 10 which is supplied at its upstream end with food to be distributed, for example stored in a hopper 11. The linear conveyor 10 is for example made up of a tube housing an Archimedes screw which is rotated at by means of an advantageously electric motor 12. In order to be able to feed the conveyor tube 10 with relatively small amounts of food, the Archimedes screw 11 is, according to the present invention, a hollow screw, for example made up of a relatively thick wire wound helically. The height of the food in the tube of the conveyor 10 cannot exceed the thickness of the wire.
Comme cela est représenté à la Fig. 3, le tube du convoyeur 10 comporte dans sa partie inférieure des lumières 16 (par exemple rectangulaires) permettant à l'aliment qu'il transporte de se déverser, comme cela sera expliqué dans la suite de la description. De plus, ces lumières 16 sont espacées entre elles par des interstices 16' dont la largeur est de l'ordre de grandeur de la largeur des lumières 16. Par exemple, ces largeurs sont identiques. Comme on le verra par la suite, ces interstices 16' constituent des réserves d'aliment qui sont rapidement disponibles après distribution de l'aliment qui se trouvait en face des lumières 16 et sont déversées, par les lumières 16, après rotation de la vis du convoyeur 10 de quelques tours. Ces réserves permettent également d'ajuster la quantité d'aliment distribué, là aussi, par rotation de la vis du convoyeur 10 de la quantité voulues.As shown in FIG. 3, the conveyor tube 10 has in its lower part lights 16 (for example rectangular) allowing the food which it carries to pour out, as will be explained in the following description. In addition, these slots 16 are spaced apart by interstices 16 'whose width is of the order of magnitude of the width of the slots 16. For example, these widths are identical. As will be seen later, these interstices 16 ′ constitute food reserves which are quickly available after distribution of the food which was in front of the lights 16 and are discharged, by the lights 16, after rotation of the screw of the conveyor 10 a few turns. These reserves also make it possible to adjust the quantity of food dispensed, here too, by rotation of the screw of the conveyor 10 by the desired quantity.
Selon un mode avantageux, le tube du convoyeur 10 est avantageusement constitué d'une coquille inférieure 14 et d'une coquille supérieure 15, ce qui permet, après avoir enlevé la coquille supérieure 15, d'avoir accès à l'élément d'entraînement du convoyeur 10. Cet élément d'entraînement est par exemple une vis d'Archimède qu'il est alors possible de nettoyer et de désinfecter au moyen d'une soufflette ou d'un lavage haute-pression. Disposée sous toute la longueur du convoyeur linéaire 1 , est prévue une augeAccording to an advantageous embodiment, the conveyor tube 10 advantageously consists of a lower shell 14 and an upper shell 15, which allows, after removing the upper shell 15, to have access to the drive element of the conveyor 10. This drive element is for example an Archimedes screw which it is then possible to clean and disinfect by means of a blower or a high-pressure wash. Arranged under the entire length of the linear conveyor 1, a trough is provided
20 dans laquelle les animaux peuvent picorer les aliments qu'elle contient. L'auge 20 est rendue solidaire du convoyeur linéaire au moyen de blocs support 21 auxquels elle est fixée au moyen de pattes 24a et 24b (voir détails sur les Figs. 2a à 2c) et qui sont régulièrement espacés le long du convoyeur 10. On notera que l'on ne sortira pas du cadre de l'invention, si au lieu d'une auge20 in which animals can peck at the food it contains. The gauge 20 is made integral with the linear conveyor by means of support blocks 21 to which it is fixed by means of lugs 24a and 24b (see details in Figs. 2a to 2c) and which are regularly spaced along the conveyor 10. On note that it will not depart from the scope of the invention, if instead of a trough
20, sont placées sous le convoyeur 10, plusieurs auges contiguës.20, are placed under the conveyor 10, several contiguous troughs.
Dans le mode de réalisation représenté à la Fig. 1, les blocs support 21 amont et aval sont reliés au plafond du local dans lequel est installé le système de distribution au moyen de filins 22 qui permettent ainsi la suspension de l'ensemble du système de distribution d'aliments de l'invention. Un treuil (non représenté) peut être prévu pour ajuster la longueur des filins 22 et ainsi modifier la hauteur de l'ensemble du système de distribution et, ce, en fonction de l'âge des animaux. Avec un tel treuil, il est également possible d'ajuster l'horizontalité du système de distribution.In the embodiment shown in FIG. 1, the upstream and downstream support blocks 21 are connected to the ceiling of the room in which the distribution system is installed by means of cables 22 which thus allow the suspension of the entire food distribution system of the invention. A winch (not shown) can be provided to adjust the length of the ropes 22 and thus modify the height of the entire distribution system, depending on the age of the animals. With such a winch, it is also possible to adjust the horizontality of the distribution system.
Le système de distribution représenté à la Fig. 1 comporte encore des moyens de stockage 30 décrits ultérieurement dans un mode de réalisation particulier en relation avec les Figs. 2a à 2c. Ces moyens de stockage 30 sont prévus pour pouvoir prendre une première position où ils stockent les aliments transportés par le convoyeur 10 et une deuxième position où ils déversent l'ensemble de leur contenu dans l'auge 20. Ainsi, les aliments distribués apparaissent dans toute partie de l'auge 20 au même moment et en même quantité. Par conséquent, les animaux ne sont plus obligés de s'agglutiner dans une zone particulière pour pouvoir se nourrir et ne se battent plus pour ce faire.The distribution system shown in FIG. 1 further comprises storage means 30 described later in a particular embodiment in relation to FIGS. 2a to 2c. These storage means 30 are provided to be able to take a first position where they store the food transported by the conveyor 10 and a second position where they pour all of their contents into the trough 20. Thus, the distributed food appears in all part of trough 20 at the same at the same time. As a result, animals are no longer forced to congregate in a particular area to be able to feed and no longer fight to do so.
Pour pouvoir passer d'une première position à une seconde position, les moyens de stockage 30 sont commandés au moyen d'un vérin 40 et d'un câble de commandeTo be able to move from a first position to a second position, the storage means 30 are controlled by means of a jack 40 and a control cable.
41 dont la longueur peut être ajustée au moyen d'un dispositif d'ajustement 42. Un câble de liaison 43 relie le câble de commande 41 aux moyens de stockage 30 en passant dans des anneaux 17 solidaires du convoyeur linéaire 10.41, the length of which can be adjusted by means of an adjustment device 42. A connecting cable 43 connects the control cable 41 to the storage means 30 passing through rings 17 integral with the linear conveyor 10.
Une unité de pilotage 50 est prévue pour commander le moteur 12 et le vérin 40 et ce, de la manière maintenant exphcitée. Dans une première phase, le moteur 12 est mis en marche, si bien que le convoyeur 10 extrait des aliments de la trémie 11 et les transporte vers son extrémité aval. Le vérin 40 est commandé de manière que les moyens de stockage 30 prennent leur première position où ils stockent les aliments qui sont transportés par le convoyeur 10. Dans une seconde phase, le moteur 12 est arrêté et plus aucun aliment n'est transporté par le convoyeur 10. Quant au vérin 40, il est commandé de manière à ce que les moyens de stockage se retrouvent dans leur seconde position où ils déversent dans l'auge 20 l'ensemble des aliments qu'ils ont stockés.A control unit 50 is provided for controlling the motor 12 and the jack 40 and this, in the manner now described. In a first phase, the motor 12 is started, so that the conveyor 10 extracts food from the hopper 11 and transports it to its downstream end. The jack 40 is controlled so that the storage means 30 take their first position where they store the food which is transported by the conveyor 10. In a second phase, the motor 12 is stopped and no more food is transported by the conveyor 10. As for the jack 40, it is controlled so that the storage means are found in their second position where they pour into the trough 20 all the food they have stored.
On notera que la trémie 11 peut être pourvue d'un palpeur de niveau bas 13 relié électriquement à l'unité de pilotage 50 de manière à détecter la présence d'une quantité d'aliments dans la trémie 11 inférieur à un minimum. Par exemple, lors d'une telle détection, l'unité de pilotage 50 commande la mise en position des moyens de stockage 30 dans leur seconde position après un laps de temps prédéterminé.It will be noted that the hopper 11 can be provided with a low level sensor 13 electrically connected to the control unit 50 so as to detect the presence of an amount of food in the hopper 11 less than a minimum. For example, during such detection, the control unit 50 controls the positioning of the storage means 30 in their second position after a predetermined period of time.
Ainsi, lorsque dans la trémie 11, il reste à distribuer une quantité d'aliment inférieure à une dose à distribuer, il est possible de la distribuer sur une longueur du convoyeur 10 située à une distance plus ou moins grande de la trémie 11 dépendant de la grandeur du laps de temps prédéterminé.Thus, when in the hopper 11, there remains to distribute a quantity of food less than a dose to be distributed, it is possible to distribute it over a length of the conveyor 10 located at a greater or lesser distance from the hopper 11 depending on the magnitude of the predetermined period of time.
De plus, la trémie 11 est pourvue d'un volet de dosage 14 qui, en coulissant, permet de régler la section de passage des aliments de la trémie 11 vers le convoyeur 10. Ce volet de dosage permet de régler le débit d'aliments qui alimente le convoyeur 10.In addition, the hopper 11 is provided with a metering flap 14 which, by sliding, makes it possible to adjust the passage section of the food from the hopper 11 to the conveyor 10. This metering flap makes it possible to adjust the flow of food which feeds the conveyor 10.
Le système de distribution d'aliments représenté à la Fig. 1 comporte encore un dispositif de détection d'aliments 60 qui est placé à l'extrémité aval du convoyeur 10. Ce dispositif de détection 60 comprend un réservoir 61 recevant l'aliment déversé par le convoyeur 10 à son extrémité aval, et un détecteur 62 relié électriquement à l'unité de pilotage 50. Lorsqu'une quantité d'aliments prédéterminée est contenue dans le réservoir 61, le détecteur 62 émet un signal à destination de l'unité de pilotage 50. A la réception de ce signal, l'unité de pilotage 50 passe de sa première phase à sa seconde phase. Ainsi, lorsque l'aliment est déversé dans le réservoir 61, les moyens de stockage stockent suffisamment d'aliments qui peuvent alors être déversés dans l'auge 20.The food distribution system shown in FIG. 1 further comprises a food detection device 60 which is placed at the downstream end of the conveyor 10. This detection device 60 comprises a reservoir 61 receiving the food spilled by the conveyor 10 at its downstream end, and a detector 62 electrically connected to the control unit 50. When a predetermined quantity of food is contained in the tank 61, the detector 62 emits a signal intended for the piloting 50. On reception of this signal, the piloting unit 50 goes from its first phase to its second phase. Thus, when the food is poured into the tank 61, the storage means store enough food which can then be poured into the trough 20.
Le réservoir 61 comporte un fond 63 qui peut être escamoté en même temps que les moyens de stockage 30, c'est-à-dire pendant la seconde phase de l'unité de pilotage 50. Pour ce faire, le volet 63 est commandé par le vérin 40 au moyen d'un câble approprié 44.The tank 61 has a bottom 63 which can be retracted at the same time as the storage means 30, that is to say during the second phase of the control unit 50. To do this, the flap 63 is controlled by the jack 40 by means of an appropriate cable 44.
On va maintenant décrire en relation avec les Figs. 2a à 2c un mode particulier de réalisation de la présente invention.We will now describe in relation to Figs. 2a to 2c a particular embodiment of the present invention.
A la Fig. 2a, on reconnaîtra le convoyeur linéaire 10 représenté uniquement par le tube qui loge son élément d'entraînement (par exemple, une vis d'Archimède), un bloc support 21 de forme générale parallélépipédique, l'auge 20 et le moyen de stockage 30. On voit également le câble de commande 41, ainsi que le câble de liaison 43 reliant le câble de commande 41 au moyen de stockage 30. Pour guider le câble de liaison 43 entre le câble de commande 41 et le moyen de stockage 30, on a prévu un anneau 17 qui est relié par l'intermédiaire d'une patte 17a au tube du convoyeur 10.In Fig. 2a, we will recognize the linear conveyor 10 represented only by the tube which houses its drive element (for example, an Archimedean screw), a support block 21 of generally parallelepiped shape, the trough 20 and the storage means 30 The control cable 41 is also seen, as well as the connection cable 43 connecting the control cable 41 to the storage means 30. To guide the connection cable 43 between the control cable 41 and the storage means 30, has provided a ring 17 which is connected by means of a lug 17a to the tube of the conveyor 10.
Le bloc support 21 comporte un logement 21a pour loger la partie inférieure du tube du convoyeur 10. Le tube du convoyeur 10 comporte des ailes 10a et 10b qui reposent sur des épaulements 21b du bloc support 21.The support block 21 has a housing 21a for housing the lower part of the conveyor tube 10. The conveyor tube 10 has wings 10a and 10b which rest on shoulders 21b of the support block 21.
Juste au-dessus de la partie supérieure du tube du convoyeur 10 est prévue une tige 23 dont les extrémités sont fixées à des ailes 21c du bloc support 21, et ce, au moyen de boulons 23 a. Le convoyeur 10 est ainsi maintenu et rendu solidaire de chaque bloc support 21.Just above the upper part of the conveyor tube 10 is provided a rod 23 whose ends are fixed to wings 21c of the support block 21, and this, by means of bolts 23 a. The conveyor 10 is thus maintained and made integral with each support block 21.
Des pattes 24a et 24b sont fixées dans la partie supérieure du bloc support 21, par exemple au moyen de boulons 24c, et présentent une extrémité recourbée 24d et 24e destinées à recevoir les bords 20a et 20b de l'auge 20 lesquels comportent trois plis de manière à présenter un profil de U renversé. Ce montage particulier permet d'obtenir une fixation de l'auge 20 sur les pattes 24a et 24b sans nécessiter d'accessoires tels que vis, rivets, etc. Sur chaque flanc 21d de chaque bloc support 21, sont fixés, par exemple aux moyens de boulons 25a, des déflecteurs 25 constitués de plaques (par exemple de tôle) reliant deux à deux les blocs support 21. Ces déflecteurs 25 présentent un pli 25b incliné vers l'axe médian du système de distribution. Le rôle de ces déflecteurs est double : d'une part, du fait qu'ils relient les blocs support 21, ils donnent une rigidité à l'ensemble du système de distribution. D'autre part, comme on le comprendra par la suite, ils protègent les animaux du mouvement des moyens de stockage 30 en leur en empêchant l'approche.Legs 24a and 24b are fixed in the upper part of the support block 21, for example by means of bolts 24c, and have a curved end 24d and 24e intended to receive the edges 20a and 20b of the trough 20 which comprise three folds of so as to present an inverted U profile. This particular assembly makes it possible to obtain a fixing of the trough 20 on the lugs 24a and 24b without requiring accessories such as screws, rivets, etc. On each side 21d of each support block 21 are fixed, for example by means of bolts 25a, deflectors 25 made up of plates (for example of sheet metal) connecting two by two the support blocks 21. These deflectors 25 have an inclined fold 25b towards the median axis of the distribution system. The role of these deflectors is twofold: firstly, because they connect the support blocks 21, they give rigidity to the entire distribution system. On the other hand, as will be understood later, they protect the animals from the movement of the storage means 30 by preventing them from approaching.
Dans le mode de réalisation représenté à la Fig. 2a, les moyens de stockage 30 sont constitués, entre deux blocs supports 21, d'un volet 31 présentant une section en forme de N dont la pointe est tronquée. Ce volet 31 est monté pivotant sur un axe 32 parallèle à la direction longitudinale du convoyeur linéaire 10. L'axe 32 est solidaire du volet 31 par une de ses ailes latérales. Le câble 43 qui relie le câble de commande 41 au volet 31 est relié à l'extrémité de l'aile opposée à celle qui reçoit l'axe 32. La forme en N du volet permet à celui-ci d'inclure dans la position représentée à la Fig. 2a le convoyeur 10 obturant ainsi les lumières 16 prévues dans la partie inférieure du convoyeur 10.In the embodiment shown in FIG. 2a, the storage means 30 consist, between two support blocks 21, of a flap 31 having an N-shaped section whose tip is truncated. This flap 31 is pivotally mounted on an axis 32 parallel to the longitudinal direction of the linear conveyor 10. The axis 32 is integral with the flap 31 by one of its lateral wings. The cable 43 which connects the control cable 41 to the flap 31 is connected to the end of the wing opposite to that which receives the axis 32. The N-shape of the flap allows it to be included in the position shown in FIG. 2a the conveyor 10 thus closing the openings 16 provided in the lower part of the conveyor 10.
On constatera que pour maintenir le volet 31 dans la position où il obture le convoyeur 10, comme cela est représenté à la Fig. 2a, il est nécessaire de maintenir une tension sur les câbles 41 et 43. Pour ce faire, le vérin 40 (voir Fig. 1) doit être commandé. Dans cette position, les aliments qui sont transportés par le convoyeur 10 sont stockés dans la partie inférieure de celui-ci. C'est la première phase évoquée ci- dessus.It will be seen that in order to maintain the flap 31 in the position where it closes the conveyor 10, as shown in FIG. 2a, it is necessary to maintain a tension on the cables 41 and 43. To do this, the jack 40 (see Fig. 1) must be ordered. In this position, the food which is transported by the conveyor 10 is stored in the lower part thereof. This is the first phase mentioned above.
Lorsque le vérin 40 (voir Fig. 1) est relâché, il en est de même du câble de commande 41 et du câble de liaison 43. Par son propre poids, le volet 31 pivote autour de l'axe 32 et se retrouve dans une position escamotée où les aliments qui étaient contenus dans la partie inférieure du convoyeur 10 sont déversés dans l'auge 20 et sont ainsi distribués aux animaux qui peuvent les picorer. Il s'agit là de la seconde phase de fonctionnement de l'unité de pilotage 50. Cette situation est représentée à la Fig. 2c. On constatera que les moyens de stockage 30 jouent le rôle ici de simples moyens d'obturation des lumières du convoyeur 10.When the jack 40 (see Fig. 1) is released, the same applies to the control cable 41 and the connection cable 43. By its own weight, the flap 31 pivots around the axis 32 and is found in a retracted position where the food which was contained in the lower part of the conveyor 10 is poured into the trough 20 and is thus distributed to the animals which can peck at it. This is the second operating phase of the control unit 50. This situation is shown in FIG. 2c. It will be noted that the storage means 30 play the role here of simple means for shutting off the lights of the conveyor 10.
On a représenté à la Fig. 2b une position intermédiaire des moyens de stockage 30 où ceux-ci jouent maintenant le rôle de moyens de réserve. Dans cette position, par un réglage approprié de moyens 42 servant au réglage de la longueur du câble de commande 41, le câble de commande 41 ainsi que le câble de Maison 43 sont légèrement relâchés par rapport à ce qu'ils étaient à la Fig. 2a, si bien que le volet 31 n'obture plus les lumières 16 du convoyeur 10. Néanmoins, comme le volet 31 présente deux ailes 31a et 31b, l'aliment transporté par le convoyeur 10 ne se déverse pas directement dans l'auge 20, mais est au contraire stocké dans la partie du volet 31 qui se trouve en dessous des lumières 16 du convoyeur 10. Comme précédemment, lorsque le vérin 40 (voir Fig. 1) est relâché, il en est de même des câbles 41 et 43, si bien que le moyen de stockage 30 se retrouve dans la position représentée à la Fig. 2c où les aliments qu'il contient se déversent dans l'auge 20. Ce mode de fonctionnement permet de stocker une plus grande quantité d'aliments. Par ailleurs, par réglage de la longueur du câble de commande 41 par une manœuvre appropriée des moyens de réglage 42, il est possible d'ajuster l'angle de pivotement des moyens de stockage 30 et par conséquent la distance séparant le convoyeur 10 du volet 31, et ainsi de faire varier le volume de stockage à l'intérieur du V formé par le volet 31.There is shown in FIG. 2b an intermediate position of the storage means 30 where these now play the role of reserve means. In this position, by an appropriate adjustment of means 42 for adjusting the length of the cable control 41, the control cable 41 as well as the house cable 43 are slightly relaxed compared to what they were in FIG. 2a, so that the flap 31 no longer closes the openings 16 of the conveyor 10. However, since the flap 31 has two wings 31a and 31b, the food transported by the conveyor 10 does not pour directly into the trough 20 , but is instead stored in the part of the flap 31 which is located below the lights 16 of the conveyor 10. As before, when the jack 40 (see Fig. 1) is released, the same is true of the cables 41 and 43 , so that the storage means 30 is found in the position shown in FIG. 2c where the food it contains flows into the trough 20. This operating mode makes it possible to store a larger quantity of food. Furthermore, by adjusting the length of the control cable 41 by an appropriate operation of the adjusting means 42, it is possible to adjust the pivoting angle of the storage means 30 and consequently the distance separating the conveyor 10 from the shutter. 31, and thus to vary the storage volume inside the V formed by the flap 31.
On comprendra que le mode de réalisation représenté aux Figs. 2a à 2c peut fonctionner indifféremment dans un mode de fonctionnement ou l'autre. Cependant, sans sortir du cadre de la présente invention, des modes de réalisation particuliers peuvent ne fonctionner que dans un mode de fonctionnement ou l'autre. Des grilles 26 peuvent être prévues de chaque côté de l'auge 20 et sont par exemple montées entre les bords 20a et 20b de l'auge 20 et des replis 25c formés dans la partie inférieure des déflecteurs 25. Ces grilles 26 sont maintenues en place par un effet d'élasticité des déflecteurs 25 qui les contraint à être logées entre les bords 20a et 20b de l'auge 20. La cinquième travée de la Fig. 1 comporte une telle grille 26. Ces grilles 26 autorisent, en fonction de la distance qui séparent deux de leurs fils adjacents mais aussi en fonction de la grosseur de tête de l'arrimai, l'accès ou non à l'auge 20.It will be understood that the embodiment shown in Figs. 2a to 2c can operate indifferently in one operating mode or the other. However, without departing from the scope of the present invention, particular embodiments may function only in one operating mode or the other. Grids 26 can be provided on each side of trough 20 and are for example mounted between the edges 20a and 20b of trough 20 and folds 25c formed in the lower part of the deflectors 25. These grids 26 are held in place by an elasticity effect of the deflectors 25 which forces them to be housed between the edges 20a and 20b of the trough 20. The fifth span of FIG. 1 includes such a grid 26. These grids 26 allow, depending on the distance which separate two of their adjacent wires but also depending on the size of the head of the stowage, access or not to the trough 20.
Par ailleurs, le système de distribution d'aliments de l'invention peut être chapeauté d'un chapeau 27 posé par ses bords latéraux sur chaque bloc support 21. Furthermore, the food distribution system of the invention can be capped with a cap 27 placed by its lateral edges on each support block 21.
