Abstract

The unit has individual cutting units mounted with longitudinal phase and are alternatively resulted in disposition. The cutting blades are physically independent of the disc on which they are mounted, so that they can be disassembled by removing the screws to be sharpened or to be replaced, without having the necessity of disassembling the entire unit of supplementary shaft.

Description

Unidad de corte para trituradores de doble eje y velocidad lenta.Cutting unit for double shaft shredders and slow speed.

Objeto de la invenciónObject of the invention

La presente invención se refiere a una unidad de corte destinada a formar parte de un triturador de doble eje, en cada uno de cuyos ejes se monta una pluralidad de unidades de corte que trabajan sincronizada y alternadamente, mediante movimiento giratorio de los ejes con velocidad lenta.The present invention relates to a unit of cut intended to be part of a double shaft shredder, in each of whose axes a plurality of cutting units is mounted that work synchronously and alternately, by movement Rotating axes with slow speed.

El objeto de la invención es conseguir, por un lado una unidad de corte en la que las cuchillas son fácilmente desmontables para su mantenimiento o sustitución, y por otro lado que dicha unidad de corte resulte eficaz en múltiples aplicaciones prácticas, tales como la trituración de neumáticos usados, de mazarotas de plástico, de bidones de plástico, de bidones de acero, de cables eléctricos, de palets, etc.The object of the invention is to achieve, by a side a cutting unit in which the blades are easily removable for maintenance or replacement, and on the other hand that said cutting unit is effective in multiple applications practices, such as crushing used tires, from plastic cups, plastic drums, steel drums, of electric cables, pallets, etc.

La invención resulta pues aplicable al ámbito de la trituración de todo tipo de residuos, con miras al reciclado de los mismos.The invention is therefore applicable to the field of the crushing of all types of waste, with a view to recycling the same.

Antecedentes de la invenciónBackground of the invention

Como es sabido, los trituradores de velocidad lenta disponen de dos ejes paralelos, debidamente motorizados y montados sobre robustos rodamientos, participando en cada uno de dichos ejes una pluralidad de unidades de corte, uniformemente distribuidas con el concurso de distanciadores axiales, de manera que las unidades de corte de un eje quedan desfasadas longitudinalmente con respecto a las del otro, con una disposición alternada que facilita la trituración.As is known, speed breakers Slowly they have two parallel axes, properly motorized and mounted on robust bearings, participating in each of said axes a plurality of cutting units, uniformly distributed with the axial spacers contest, so that the axle cutting units are out of date longitudinally with respect to those of the other, with an arrangement alternated that facilitates crushing.

De forma más concreta, dichas unidades de corte se materializan en una especie de aspa (1) (ver figura 1), con un orificio central y poligonal (2) para su acoplamiento enchavetado al eje y para poder ser arrastrada por el mismo, aspa en cuya periferia y con carácter monopieza se definen las cuchillas (3).More specifically, said cutting units they materialize in a kind of blade (1) (see figure 1), with a central and polygonal hole (2) for keyed coupling to the axis and to be able to be dragged by it, blade in whose periphery and with single piece character the blades are defined (3).

Estas unidades de corte, ya sean de acero fundido o de acero oxicortado, presentan como problema fundamental el elevado costo que supone dar un tratamiento térmico a toda la unidad adecuado para que las cuchillas (3) alcancen la dureza conveniente.These cutting units, whether made of steel cast or oxycut steel, present as a fundamental problem the high cost of giving a heat treatment to the entire suitable unit for the blades (3) to reach hardness convenient.

Otro inconveniente no menos importante es que cuando las cuchillas (3) se desgastan es necesario cambiar la unidad de corte completa desmotando los ejes de giro y sustituyendo los discos desgastados, habitualmente todos los discos, operaciones que suponen un costo económico elevado y una pérdida de tiempo considerable, ya que las operaciones de desmontaje y montaje de los nuevos discos de corte requieren muchas horas de trabajo de mantenimiento.Another disadvantage not less important is that when the blades (3) wear out it is necessary to change the complete cutting unit gutting the axes of rotation and replacing worn discs, usually all discs, operations which involve a high economic cost and a waste of time considerable, since the disassembly and assembly operations of new cutting discs require many hours of work from maintenance.

Descripción de la invenciónDescription of the invention

La unidad de corte que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, en los diferentes aspectos comentados.The cutting unit that the invention proposes solves the problem fully satisfactorily previously exposed, in the different aspects commented.

Para ello, de forma más concreta y de acuerdo con una de las características de la invención, en cada unidad de corte participa un disco soporte, el destinado a fijarse al eje, y una pluralidad de cuchillas montadas con carácter amovible sobre dicho disco, de manera que el desmontaje de las cuchillas, para mantenimiento de las mismas, puede efectuarse sin necesidad de desmontar el disco soporte del correspondiente eje, lo que facilita de forma muy considerable estas maniobras de mantenimiento.To do this, more specifically and in agreement with one of the characteristics of the invention, in each unit of cut participates a support disk, the one intended to be fixed to the shaft, and a plurality of blades mounted with removable character on said disk, so that the disassembly of the blades, for maintenance of them, can be done without the need for disassemble the support disk of the corresponding shaft, which facilitates very considerably these maintenance maneuvers.

De acuerdo con otra de las características de la invención en la periferia del disco soporte se establecen ranuras mecanizadas, formal y dimensionalmente adecuadas para recibir en su seno a respectivos chaveteros macho configurados en la base de las cuchillas, de manera que en la fijación de estas últimas al disco soporte, por atornillamiento, se consigue una sólida unión entre estos elementos capaz de soportar los notables esfuerzos angulares que supone el impacto de las cuchillas sobre el material a triturar.According to another of the characteristics of the invention on the periphery of the support disk grooves are established mechanized, formally and dimensionally suitable to receive in your sine to respective male keyways configured at the base of the blades, so that in fixing the latter to the disk support, by screwing, a solid bond is achieved between these elements able to withstand the remarkable angular efforts which supposes the impact of the blades on the material a Crush.

Cada cuchilla se fija al disco soporte mediante una pareja de tornillos que la atraviesan y cuyas cabezas quedan embutidas en el seno de la misma, roscando en orificios ciegos del disco soporte.Each blade is fixed to the support disk by a pair of screws that go through it and whose heads are left embedded in it, threading into blind holes in the support disk

De acuerdo con otra de las características de la invención se ha previsto que las cuchillas de corte queden sustancialmente distanciadas en la periferia del disco soporte y se sitúen alternadamente con otras cuchillas complementarias que sirven de prolongación a las cuchillas de corte propiamente dichas y que tienen como función esencial proteger del desgaste al disco soporte.According to another of the characteristics of the invention is provided that the cutting blades remain substantially distanced at the periphery of the support disk and it alternately position with other complementary blades that serve as an extension to the cutting blades themselves and whose essential function is to protect the disk from wear support.

Para conseguir la amplia gama de posibilidades de utilización práctica de una trituradora con este tipo de unidades de corte, las cuchillas deben alcanzar una dureza de 59 HRc.To achieve the wide range of possibilities of practical use of a crusher with this type of cutting units, the blades must reach a hardness of 59 HRc
