COMEDERO AVÍCOLA DE DOSIFICACIÓN REGULABLE Y CONOCIDAPOULTRY FEEDER WITH ADJUSTABLE AND KNOWN DOSAGE

La presente invención se enmarca en el campo de los comederos para la cría de aves de corral de cualquier edad, especialmente de pavos.The present invention is part of the field of feeders for raising poultry of any age, especially turkeys.

Antecedentes de la invenciónBackground of the invention

Son conocidos en el estado de la técnica los comederos avícolas de dosificación regulable, los cuales son adecuados para dosificar el alimento a las aves, tanto en su etapa de recría como posteriormente en su engorde.Adjustable dosage poultry feeders are known in the state of the art, which are suitable for dispensing feed to birds, both in their rearing stage and later in their fattening.

Por ejemplo, los documentos EP0658303A1 y EP2277374A1 divulgan comederos de dosificación regulable, los cuales comprenden un plato con un orificio central en el que se fija un vástago roscado, al cual también se fija una tolva con un asiento en su extremo inferior sujetado por unos nervios. La regulación del caudal de alimento que cae desde la tolva hacia el plato se realiza mediante la regulación de la separación entre la tolva y el plato, gracias a la rosca entre el vástago y la tolva. Sin embargo, de esta forma resulta difícil regular el caudal de forma conocida y repetible por parte del criador.For example, documents EP0658303A1 and EP2277374A1 disclose troughs with adjustable dosage, which comprise a plate with a central hole in which a threaded stem is attached, to which a hopper is also attached with a seat at its lower end held by ribs. . The regulation of the flow of food that falls from the hopper to the plate is done by regulating the separation between the hopper and the plate, thanks to the thread between the stem and the hopper. However, in this way it is difficult to regulate the flow in a known and repeatable way by the breeder.

Por lo tanto, resulta clara la necesidad de proporcionar un comedero avícola que permita regular la dosificación del alimento de forma conocida y repetible.Therefore, it is clear the need to provide a poultry feeder that allows to regulate the feed dosage in a known and repeatable way.

Descripción de la invenciónDescription of the invention

El objetivo de la presente invención es el de proporcionar un comedero avícola que resuelve los inconvenientes citados y presenta las ventajas que se describen a continuación.The aim of the present invention is to provide a poultry feeder that solves the aforementioned drawbacks and has the advantages that are described below.

De acuerdo con este objetivo, el presente comedero avícola de dosificación regulable y conocida, comprende:In accordance with this objective, the present known and adjustable dosage poultry feeder comprises:

- un plato inferior que incluye una base, un labio anti desperdicio en su periferia externa y un vástago central con una rosca externa, y- a bottom plate including a base, an anti-waste lip on its outer periphery and a central stem with an external thread, and

- una tolva, en cuyo extremo inferior comprende dos o más nervios proyectados radialmente hacia el interior, los cuales sustentan un asiento central con una rosca interna y complementaria a la rosca externa del vástago central. - a hopper, at the lower end of which it comprises two or more ribs projecting radially inward, which support a central seat with an internal thread and complementary to the external thread of the central rod.

El presente comedero se caracteriza por el hecho de que el vástago central y el asiento central comprenden medios de posicionamiento selectivo, complementarios entre ellos y configurados para posicionar selectivamente la tolva respecto al plato inferior en posiciones predefinidas.The present trough is characterized by the fact that the central stem and the central seat comprise selective positioning means, complementary to each other and configured to selectively position the hopper with respect to the lower plate in predefined positions.

Gracias a disponer de medios de posicionamiento selectivo, se permite regular fácilmente la ración y adaptarla a las necesidades del ave de forma controlada y repetible. Además, el final del recorrido de la rosca aporta una posición fija y exacta de cierre de la ración del comedero, al encajar el extremo inferior de la tolva con el plato inferior. Para ello, preferentemente la base del plato dispone de una porción cónica que asciende desde la base hasta el vástago central, y dichos nervios de la tolva tienen una inclinación igual o mayor que la porción cónica del plato.Thanks to having selective positioning means, it is possible to easily regulate the ration and adapt it to the needs of the bird in a controlled and repeatable way. In addition, the end of the thread travel provides a fixed and exact closing position of the feeder ration, by engaging the lower end of the hopper with the lower plate. For this, preferably the base of the plate has a conical portion that rises from the base to the central stem, and said ribs of the hopper have an equal or greater inclination than the conical portion of the plate.

En una realización concreta, dichos medios de posicionamiento selectivo consisten en al menos un saliente situado en la trayectoria de la rosca externa del vástago central y al menos una hendidura o tramo sin rosca situado en la rosca interna de la tolva, siendo el saliente y la hendidura o tramo sin rosca encajables entre sí. En una realización aún más concreta de dichos medios de posicionamiento selectivo, la rosca externa del vástago central está definida por dos hilos, entre los cuales se encuentra guiada la rosca interna de la tolva. A su vez, esta rosca externa de doble hilo comprende un tramo interrumpido (es decir, sin rosca), preferiblemente en la mitad de su desarrollo, y en medio del cual hay un saliente troncocónico. Por su parte, la rosca interna de la tolva comprende varios tramos sin rosca, siendo susceptibles de encajar en dicho saliente troncocónico. Estos diferentes tramos sin rosca definen las diferentes posiciones de regulación de la dosificación. De forma preferente, el material del que se encuentra fabricado la tolva en general, y el de la rosca interna en particular, dispone de suficiente elasticidad que permite que al aplicar un poco de fuerza al roscar o desenroscar ambas piezas, el saliente salte de un tramo sin rosca a otro, permitiendo la regulación de forma repetible y difícilmente alterable por los golpes y movimientos a los que las aves pueden someter el comedero.In a specific embodiment, said selective positioning means consist of at least one projection located in the path of the external thread of the central stem and at least one slot or section without thread located in the internal thread of the hopper, the projection and the slot or non-threaded section that can be interlocked. In an even more specific embodiment of said selective positioning means, the external thread of the central rod is defined by two threads, between which the internal thread of the hopper is guided. In turn, this external double-wire thread comprises an interrupted section (that is, without thread), preferably in the middle of its development, and in the middle of which there is a frustoconical projection. For its part, the internal thread of the hopper comprises several non-threaded sections, being capable of fitting into said frustoconical projection. These different non-threaded sections define the different dosage adjustment positions. Preferably, the material from which the hopper is made in general, and that of the internal thread in particular, has sufficient elasticity that allows that when a little force is applied when screwing or unscrewing both pieces, the projection jumps out of a non-threaded section to another, allowing the regulation in a repeatable way and difficult to alter by the blows and movements to which the birds can subject the feeder.

Preferentemente, el plato inferior y el vástago central son componentes independientes. En este caso, el plato inferior comprende un orificio central con medios de fijación internos, mientras que el vástago central comprende medios de fijación externos en su tramo inferior y complementarios a dichos medios de fijación internos del plato inferior. Gracias a ello, los moldes de fabricación son más económicos y su limpieza resulta más sencilla. Preferably, the bottom plate and the center rod are independent components. In this case, the lower plate comprises a central hole with internal fixing means, while the central stem comprises external fixing means in its lower section and complementary to said internal fixing means of the lower plate. Thanks to this, the manufacturing molds are cheaper and their cleaning is easier.

Sendos medios de fijación pueden consistir en elementos de clipaje a presión, ya sea por traslación longitudinal o por rotación alrededor del eje longitudinal de ambos. Con ellos se dificulta que de forma accidental el vástago se desencaje del plato inferior debido a los golpes a los que las aves pueden someter el comedero.Both fixing means can consist of pressure clipping elements, either by longitudinal translation or by rotation around the longitudinal axis of both. With them, it is difficult for the stem to accidentally disengage from the lower plate due to the blows to which the birds can subject the feeder.

En una realización preferente, el comedero comprende medios de suspensión para suspenderse de una tubería de un sistema de suministro automático de pienso. Cuando se acopla a este tipo de sistemas motorizados, el comedero se llena de forma automática. En una realización concreta, los medios de suspensión disponen de un elemento tubular y un elemento anular, donde el elemento tubular comprende en su extremo superior un sistema de clipaje, configurados para fijarse a dicha tubería, mientras que en su extremo inferior comprende un asiento externo. Por su parte, el elemento anular comprende en su extremo superior un asiento interno configurado para soportarse en el asiento externo del cilindro, a la vez que en su extremo inferior comprende un sistema de anclaje anular, configurado para anclarse al borde superior de la tolva. En esta configuración, el pienso circula por el interior de las tuberías, las cuales tienen unos orificios por donde cae el pienso hacia el interior del elemento tubular hasta llegar el plato. Para regular la dosificación, esta realización comprende una pieza de regulación, la cual es desplazable longitudinalmente por fuera del elemento tubular, a la vez que la pieza y el elemento comprenden medios de bloqueo del desplazamiento entre ellos. Por ejemplo, el elemento tubular puede incluir unas ranuras transversales externas, distribuidas longitudinalmente en una sección de su perímetro, mientras que la pieza de regulación comprende un abultamiento interno encajable en dichas ranuras transversales al ser rotada la pieza de regulación. En esta realización, por tanto, la regulación se lleva a cabo mediante el ajuste de la separación entre el plato y la pieza de regulación. Inicialmente se desplaza longitudinalmente la pieza de regulación hasta la posición de regulación deseada, y posteriormente se rota, quedando bloqueado su abultamiento en la correspondiente ranura transversal del elemento tubular.In a preferred embodiment, the feeder comprises suspension means to be suspended from a pipe of an automatic feed supply system. When coupled to this type of motorized system, the feeder fills automatically. In a specific embodiment, the suspension means have a tubular element and an annular element, where the tubular element comprises at its upper end a clipping system, configured to be fixed to said pipe, while at its lower end it comprises an external seat . For its part, the annular element comprises at its upper end an internal seat configured to be supported on the external seat of the cylinder, while at its lower end it comprises an annular anchoring system, configured to anchor to the upper edge of the hopper. In this configuration, the feed circulates inside the pipes, which have holes through which the feed falls into the tubular element until it reaches the plate. To regulate the dosage, this embodiment comprises a regulation piece, which is longitudinally movable outside the tubular element, while the piece and the element comprise means for blocking the movement between them. For example, the tubular element can include external transverse grooves, longitudinally distributed in a section of its perimeter, while the adjustment piece comprises an internal bulge that can be nested in said transverse grooves when the adjustment piece is rotated. In this embodiment, therefore, the regulation is carried out by adjusting the gap between the plate and the regulating piece. Initially, the adjustment piece is longitudinally displaced to the desired adjustment position, and subsequently it is rotated, its bulge being blocked in the corresponding transverse groove of the tubular element.

De forma preferente, los medios de suspensión o la tolva comprenden un gancho, mientras que el otro de los dos comprende un eje, siendo el gancho y el eje encajables entre sí. Es decir, los medios de suspensión pueden comprender un gancho en su extremo inferior y la tolva comprender un eje en su extremo superior, o bien los medios de suspensión pueden comprender un eje en su extremo inferior y la tolva comprender un gancho en su extremo superior. De esta forma, es posible limpiar el comedero por dentro sin necesidad de separar sus componentes entre ellos, evitando así que puedan perderse. Preferably, the suspension means or the hopper comprise a hook, while the other of the two comprises a shaft, the hook and the shaft being interlocking. That is, the suspension means can comprise a hook at its lower end and the hopper comprise a shaft at its upper end, or the suspension means can comprise a shaft at its lower end and the hopper comprise a hook at its upper end . In this way, it is possible to clean the inside of the trough without having to separate its components from each other, thus preventing them from getting lost.

Preferiblemente, las dimensiones de dichos medios de suspensión son tal que, permaneciendo cerrado el espacio entre el plato y la tolva, se pueden alimentar a través de la apertura superior de la tolva las aves que han alcanzado un cierto tamaño.Preferably, the dimensions of said suspension means are such that, with the space between the tray and the hopper remaining closed, birds which have reached a certain size can be fed through the upper opening of the hopper.

Opcionalmente, el comedero puede comprender un collar removible, el cual extiende la superficie de la tolva. Para ello, dispone de unos medios de fijación al borde superior de la tolva.Optionally, the feeder may comprise a removable collar, which extends the surface of the hopper. For this, it has fixing means to the upper edge of the hopper.

Descripción de realizaciones preferentesDescription of preferred embodiments

A continuación, se describen unas realizaciones preferentes del presente comedero avícola de dosificación regulable y conocida, haciendo referencia a las figuras 1 a 6.In the following, preferred embodiments of the present known and adjustable dosage poultry feeder are described, with reference to Figures 1 to 6.

En las figuras de la 1 a la 3 se ilustra una primera realización de dicho comedero y sus componentes. En concreto, la figura 3 muestra el plato inferior (1) de esta realización, el cual comprende:Figures 1 to 3 illustrate a first embodiment of said feeder and its components. Specifically, figure 3 shows the lower plate (1) of this embodiment, which comprises:

- una base horizontal (10),- a horizontal base (10),

- un labio anti desperdicio (11) en su periferia externa, - an anti-waste lip (11) on its outer periphery,

- un vástago central (2) con una rosca externa (21), y- a central rod (2) with an external thread (21), and

- una porción cónica (12) que asciende desde la base horizontal (10) hasta el vástago central (2).- a conical portion (12) that rises from the horizontal base (10) to the central stem (2).

A su vez, en la figura 2 se aprecia la tolva (3) del presente comedero, la cual comprende:In turn, figure 2 shows the hopper (3) of the present feeder, which comprises:

- cuatro nervios (31) en el extremo inferior, proyectados radialmente hacia el interior de la tolva (3), y- four ribs (31) at the lower end, projecting radially towards the inside of the hopper (3), and

- un asiento central (32), sustentado por dichos nervios (31), con una rosca interna (33) complementaria a la rosca externa (21) del vástago central (2).- a central seat (32), supported by said ribs (31), with an internal thread (33) complementary to the external thread (21) of the central rod (2).

En esta realización preferente, la rosca externa (21) del vástago central (2) comprende un tramo interrumpido, en medio del cual se encuentra un saliente (21’) troncocónico. A su vez, la rosca externa (21) está formada por dos hilos, cuya separación es apta para guiar entre ellos la rosca interna (33) de la tolva (3). Por su lado, la rosca interna (33) de la tolva (3) comprende varios tramos sin rosca (33’). Dicho saliente (21’) y dichos tramos sin rosca (33’) son encajables entre sí, formando unos medios de posicionamiento selectivo que permiten posicionar selectivamente la tolva (3) respecto al plato inferior (1) en posiciones predefinidas. In this preferred embodiment, the external thread (21) of the central rod (2) comprises an interrupted section, in the middle of which is a frustoconical projection (21 '). In turn, the external thread (21) is formed by two threads, the spacing of which is suitable to guide the internal thread (33) of the hopper (3) between them. For its part, the internal thread (33) of the hopper (3) comprises several non-threaded sections (33 '). Said projection (21 ') and said non-threaded sections (33') are nestable together, forming selective positioning means that allow the hopper (3) to be selectively positioned with respect to the lower plate (1) in predefined positions.

Como es de suponer, el hecho de enroscar y desenroscar la tolva (3) produce su acercamiento y retroceso, respectivamente, con respecto al plato inferior (1). Gracias a la presente configuración, los medios de posicionamiento selectivo del vástago central (2) y de la tolva (3) interactúan para transferir de una manera regulable y selectiva el pienso al plato inferior (1). As might be expected, the fact of screwing and unscrewing the hopper (3) produces its approach and retreat, respectively, with respect to the lower plate (1). Thanks to the present configuration, the means of selective positioning of the central rod (2) and of the hopper (3) interact to transfer the feed to the lower plate (1) in an adjustable and selective manner.

En relación a los nervios (31) de esta realización, comprenden una inclinación igual a la porción cónica (12) del plato inferior (1), de forma que encajan entre ellos al enroscar la tolva (3) a su posición de cierre.In relation to the ribs (31) of this embodiment, they comprise an inclination equal to the conical portion (12) of the lower plate (1), so that they fit between them when the hopper (3) is screwed into its closed position.

Esta primera realización del comedero facilita el inicio de alimentación en las aves hasta los 15 días (pudiéndose extender a más días al acoplarse a sistemas automáticos, como se verá en las siguientes realizaciones, puesto que están fijados y son más estables). El diseño del espacio entre el plato inferior (1) y la tolva (3) no permite que las aves entren y hagan sus necesidades en el interior, perjudicando el alimento, mientras que no se produce desperdicio gracias al labio anti desperdicio (11).This first embodiment of the feeder facilitates the start of feeding in the birds up to 15 days (being able to extend to more days when coupled to automatic systems, as will be seen in the following embodiments, since they are fixed and are more stable). The design of the space between the lower plate (1) and the hopper (3) does not allow the birds to enter and relieve themselves inside, damaging the feed, while there is no waste thanks to the anti-waste lip (11).

En las figuras 4 y 5 se ilustra una segunda realización de dicho comedero, donde además se aprecian unos medios de suspensión (4) para suspender el comedero de una tubería (T) de un sistema de suministro automático de pienso (del cual sólo se muestra la tubería). En esta realización, los medios de suspensión (4) disponen de:Figures 4 and 5 illustrate a second embodiment of said feeder, where there are also suspension means (4) to suspend the feeder from a pipe (T) of an automatic feed supply system (of which only the piping is shown). In this embodiment, the suspension means (4) have:

- un elemento tubular (41) que comprende en su extremo superior un sistema de clipaje (41a, 41b), configurado para fijarse a dicha tubería (T), y en su extremo inferior comprende un asiento externo (41c), y- a tubular element (41) comprising at its upper end a clipping system (41a, 41b), configured to be fixed to said pipe (T), and at its lower end it comprises an external seat (41c), and

- un elemento anular (42), el cual comprende en su extremo superior un asiento interno (42a) configurado para soportarse en dicho asiento externo (41c) del elemento tubular (41), a la vez que en su extremo inferior comprende un sistema de anclaje anular (42b) configurado para anclarse al borde superior de la tolva (3).- An annular element (42), which comprises at its upper end an internal seat (42a) configured to be supported on said external seat (41c) of the tubular element (41), while at its lower end it comprises a system of annular anchor (42b) configured to anchor to the upper edge of the hopper (3).

A su vez, esta realización comprende una pieza de regulación (6), la cual es desplazable longitudinalmente por fuera del elemento tubular (41). En este caso, el elemento tubular (41) incluye unas ranuras transversales (41d), distribuidas longitudinalmente en una sección de su perímetro, mientras que la pieza de regulación (6) comprende un abultamiento interno (61) encajable en dichas ranuras transversales (41d) al ser rotada la pieza de regulación (6). In turn, this embodiment comprises a regulation piece (6), which is longitudinally movable outside the tubular element (41). In this case, the tubular element (41) includes transverse grooves (41d), distributed longitudinally in a section of its perimeter, while the adjustment piece (6) comprises an internal bulge (61) that can be fitted in said transverse grooves (41d ) when the adjustment piece (6) is rotated.

Así mismo, esta realización comprende un collar removible (5), en cuyo perímetro interior dispone de medios de fijación (51) al borde superior de la tolva (3).Likewise, this embodiment comprises a removable collar (5), on the inner perimeter of which it has fixing means (51) to the upper edge of the hopper (3).

En la figura 6 se ilustra una tercera realización de dicho comedero, donde los medios de suspensión (4) comprenden un gancho (42c), en concreto en el extremo inferior del elemento anular (42), mientras que la tolva (3) comprende un eje (34) en su extremo superior, siendo el gancho (42c) y el eje (34) encajables entre sí.Figure 6 illustrates a third embodiment of said feeder, where the suspension means (4) comprise a hook (42c), specifically at the lower end of the annular element (42), while the hopper (3) comprises a shaft (34) at its upper end, the hook (42c) and shaft (34) being interlocking.

A pesar de que se ha hecho referencia a unas realizaciones concretas de la invención, es evidente para un experto en la materia que el comedero descrito es susceptible de numerosas variaciones y modificaciones, y que todos los detalles mencionados pueden ser substituidos por otros técnicamente equivalentes, sin apartarse del ámbito de protección definido por las reivindicaciones adjuntas. Although reference has been made to specific embodiments of the invention, it is clear to a person skilled in the art that the described feeder is susceptible to numerous variations and modifications, and that all the mentioned details can be replaced by other technically equivalent ones. without departing from the scope of protection defined by the appended claims.
