- Dotar al sistema de evacuación de unas boquillas dimensionadas de modo que cualquier pieza que atraviese con un tamaño a partir de un determinado umbral por su inserción en dichas boquillas adopte una posición que necesariamente la parte superior esté en zona de corte, mejorando así la calidad del triturado.Endow the system of evacuation of nozzles sized so that any piece that crosses with a size from a certain threshold by its insertion in said nozzles take a position that necessarily the upper part is in the cutting area, improving thus the quality of the crushed.
Con objeto de ilustrar la explicación que va a seguir, adjuntamos a la presente memoria descriptiva dos hojas de dibujos en las que en cuatro figuras se representa la esencia de la presente invención, y en las que:In order to illustrate the explanation that will follow, herewith two sheets of drawings in which the essence of the present invention, and in which:
La figura 1 muestra un detalle del fusible mecánico formado por dos discos equiaxiales separados una cierta distancia, solidario cada uno de ellos al correspondiente árbol de transmisión, unidos entre sí por una pluralidad de pernos de unión.Figure 1 shows a detail of the fuse mechanic formed by two equiaxial discs separated a certain distance, solidarity each of them to the corresponding tree of transmission, joined together by a plurality of bolts of Union.
La figura 2 muestra un detalle del dispositivo de sustentación del reductor, en el que se dispone un soporte fijo y uno dotado de características elásticas.Figure 2 shows a detail of the device lift support, in which a fixed support is provided and one endowed with elastic characteristics.
La figura 3 muestra un detalle de las faldillas de evacuación, yFigure 3 shows a detail of the skirts evacuation, and
La figura 4 muestra un ejemplo de una sección del dispositivo de evacuación.Figure 4 shows an example of a section of the evacuation device
De acuerdo con dichas figuras podemos observar en el conjunto de la figura 1 el eje de salida del reductor 2 que está solidariamente unido a un disco 3 provisto de un conjunto de orificios 4, atravesados por un conjunto de pernos 5 de unión con un segundo disco 6, solidario a un eje 7 motor del correspondiente rodillo de trituración.According to these figures we can observe in the assembly of figure 1 the output shaft of the reducer 2 which is jointly attached to a disk 3 provided with a set of holes 4, crossed by a set of connecting bolts 5 with a second disk 6, integral with a motor shaft 7 of the corresponding crushing roller.
Dichos pernos de unión 5 están calibrados de tal modo que se produzca su rotura con una carga menor que la que produciría el deterioro de cualquiera de los demás elementos.Said connecting bolts 5 are calibrated in such a way. so that its breakage occurs with a load less than it would cause deterioration of any of the other elements.
El reductor 2 dispone un eje 9 de unión con un motor de accionamiento, y está situada sobre la base 8 de una zona de la máquina trituradora externa a la de trituración.The reducer 2 has a connecting shaft 9 with a drive motor, and is located on the base 8 of an area from the external crushing machine to the crushing machine.
La sustentación sobre la base viene dada por un soporte fijo 10, consistente en la figura representada en un perno de unión de la parte superior de dicho reductor con la dicha base 8, pero pudiendo suspenderse o apoyarse de cualquier otra forma, y por un perno amortiguador 11.The lift on the basis is given by a fixed support 10, consisting of the figure represented on a bolt for joining the upper part of said reducer with said base 8, but may be suspended or supported in any other way, and by a shock absorber bolt 11.
El perno amortiguador está formado por un perno dotado de una articulación 12, preferentemente sobre la base 8, y un conjunto de arandelas 13 deformadas en forma de cucharilla (podría ser un muelle de constante elástica muy elevada, con similar resultado), de modo que dicho conjunto absorbe las pequeñas vibraciones, por una parte, y los grandes impactos, tal como cuando se produce un bloqueo de los rodillos de trituración o la rotura del fusible mecánico antes descrito.The shock absorber bolt is formed by a bolt provided with a joint 12, preferably on the base 8, and a set of deformed teaspoon-shaped washers 13 (it could be a spring of very high elastic constant, with similar result), so that said set absorbs the small vibrations, on the one hand, and the great impacts, such as when a crushing roller lock occurs or the mechanical fuse breakage described above.
Está previsto un contacto o conjunto de contactos 14 que detecta el desplazamiento del reductor cuando se produce un gran impacto, o rotura del fusible, de modo que producido el desplazamiento se manda la señal a un órgano de control, el cual ordena la parada de la máquina y genera las señales de aviso correspondientes.A contact or set of contacts is planned 14 which detects the displacement of the reducer when a great impact, or breakage of the fuse, so that produced the displacement the signal is sent to a control body, which order the machine to stop and generate the warning signals corresponding.
La salida del producto triturado podría permitir el paso de productos de cierta longitud dentro de las holguras de paso existentes entre los rodillos de trituración y las ventanas de salida del producto. Para solucionar este problema se ha contemplado la existencia de un conjunto de separadores en las ventanas de salida que impide el paso de productos largos, obligándolos a disponerse en posición vertical, para entonces ser triturados por los rodillos. Una representación pude apreciarse en las figuras 3 y 4.The output of the crushed product could allow the passage of products of a certain length within the clearances of passage between the crushing rollers and the windows of product output. To solve this problem has been contemplated the existence of a set of separators in the exit windows that prevents the passage of long products, forcing them to stand upright, then be crushed by rollers. A representation can be seen in Figures 3 and 4.
La sustentación del núcleo central contra el que actúan los rodillos trituradores se realiza por medios neumáticos, lo que permite ajustar la presión de apoyo y por tanto la fuerza de trituración admisible.The central core lift against which The crushing rollers are operated by pneumatic means, which allows to adjust the support pressure and therefore the force of admissible crushing.
