Nach einer bevorzugten Ausführungsform ist der Messerhalter in der Tasche festgeschraubt. Weitere bevorzugte Ausführungsformen sind in weiteren Unteransprüchen festgehalten.According to a preferred embodiment, the knife holder is screwed into the pocket. Further preferred embodiments are set out in further subclaims.

Das Wesen vorliegender Erfindung wird nun an Hand der beiliegenden Figuren 1 und 2, die bevorzugte Ausführungsformen der Erfindung darstellen, weiterhin erläutert.

  • Figur 1 zeigt einen Längsschnitt (abgebrochen) durch Rotormantel mit eingepasstem Messerhalter.
  • Figur 2 zeigt einen Querschnitt (abgebrochen) durch Rotormantel mit eingepasstem Messerhalter.
    • The essence of the present invention will now be further explained with the aid of the attached FIGS. 1 and 2, which represent preferred embodiments of the invention.
  • FIG. 1 shows a longitudinal section (broken off) through the rotor jacket with a fitted knife holder.
  • FIG. 2 shows a cross section (broken off) through the rotor jacket with a fitted knife holder.

    • Mit der Bezugsziffer 1 ist der Messerhalter bezeichnet, der in der im Rotormantel 9 angeordneten Tasche sich befindet und mit der Befestigungsschraube 6, die durch den Messerhalter bis in den Rotormantel hineinreicht, fixiert ist.Reference number 1 denotes the knife holder which is arranged in the rotor jacket 9 Bag is located and with the fastening screw 6 through the knife holder until it reaches into the rotor shell, is fixed.

    Mit der Bezugsziffer 2 ist das Messer bezeichnet, das auf einem Unterlageteil 5 ruht. Reference number 2 denotes the knife, which rests on a base part 5.

    Zur Fixierung ist nach einer bevorzugten Ausführungsform ein Klemmteil 3 mit Futterteil 4 vorgesehen, wobei das Klemmteil 3 mit einer Klemm- und Abdrückschraube 7 und einer Kontermutter 8 für den Abdrückvorgang zusammen arbeitet.According to a preferred embodiment, a clamping part 3 with a lining part is used for fixing 4 provided, the clamping part 3 with a clamping and forcing screw 7 and Lock nut 8 works together for the pull-off process.

    In Figur 2 sind die jeweiligen Elemente mit der gleichen Bezugsziffer gekennzeichnet wie in Figur 1.In Figure 2, the respective elements are identified with the same reference number as in Figure 1.

    Eine bevorzugte Ausführungsform des Gegenstands vorliegender Erfindung betrifft die neue und überraschend fortschrittliche Anordnung einer Messerbefestigung am Rotor solcher Zerkleinerungsmaschinen, die die Verwendung der gleichen Schneidplatte in 4-facher Weise ermöglicht, wodurch der Betrieb der Zerkleinerungsmaschinen sprunghaft verbessert und ökonomischer gestaltet wird.A preferred embodiment of the object of the present invention relates to new and surprisingly advanced arrangement of a knife attachment on the rotor such crushers that use the same insert in 4-fold way, which makes the operation of the shredding machines leaps and bounds is improved and made more economical.

    Derartige Zerkleinerungsvorrichtungen, die insbesondere zum Zerkleinern und gegebenenfalls Recyclisieren von Abfällen, insbesondere von Holzabfällen, Restholzstücken, Kunststoffen und zellulosehaltigem Material, Textilien, Teppichen und auch Kautschuk-Reifen geeignet sind, sind dem Stand der Technik bekannt.Such crushing devices, in particular for crushing and optionally Recycling of waste, in particular wood waste, pieces of residual wood, Plastics and cellulosic material, textiles, carpets and rubber tires are known from the prior art.

    Das Wesen dieser bevorzugten Ausführungsform vorliegender Erfindung ist nun in den beiliegenden Figuren 1a und 2a weiterhin erläutert.The essence of this preferred embodiment of the present invention is now in the accompanying figures 1a and 2a further explained.

    Figur 1a zeigt eine Seitenansicht, Figur 2a eine zur Seitenansicht um 90 Grad gedrehte Frontansicht. Figure 1a shows a side view, Figure 2a shows a side view rotated 90 degrees Front view.

    Mit der Bezugsziffer 1a ist der Rotor, mit 2a ein blockförmiger Messerhalter, mit 3a eine vierseitig verwendbare Schneidplatte (= Messer) mit 4a ein Abdeck- und Klemmteil, mit 5a eine Befestigungsschraube und mit 6a eine Sicherheitszentrierschraube bezeichnet.The reference number 1a is the rotor, 2a is a block-shaped knife holder, 3a is one insert that can be used on four sides (= knife) with 4a a cover and clamping part, with 5a denotes a fastening screw and 6a denotes a safety centering screw.

    Bei der erfindungsgemäßen Anordnung der Messerbefestigung am Rotor für Zerkleinerungsmaschinen ist der blockförmige Messerhalter 2a mittels einer schräg angeordneten Klemmschraube in eine gefräste Rotortasche eingesetzt. Die 4-seitig verwendbare Schneidplatte 3a (= Messer) wird in das untere gefräste Prisma des Messerhalters 2a eingesetzt und zusätzlich mit einer konischen Sicherheitszentrierschraube 6a fixiert. Durch den Abdeck- und Klemmteil 4a wird der Messerhalter 2a und die Schneidplatte 3a mit der Schraube 5a eingeschraubt, so dass sich eine formschlüssige und sicherere Befestigung des Messerhalters 2a sowie der Schneidplatte 3a ergibt.In the arrangement according to the invention of the knife attachment on the rotor for comminution machines is the block-shaped knife holder 2a by means of an obliquely arranged one Clamping screw inserted into a milled rotor pocket.
