Figure 00010001
Shredder ", for material to be shredded by the action of knives, in particular for wood shavings, plastic and cellulose-containing material, in which a rotor is provided with shredding tools, in particular knives.

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

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, die bekannten Zerkleinerungsvorrichtungen in der Weise zu verbessern, dass das lose Material selbständig zur Schnittstelle fällt und dass die Schneidmesser immer im Materialeingriff sind.The present invention is based on the object of the known size reduction devices to improve in such a way that the loose material independently Interface falls and that the cutting knives are always in the material intervention.

Diese Aufgabe wird erfindungsgemäß bei einer Zerkleinerungsvorrichtung mit der eingangs benannten Gattung dadurch gelöst, dass eine bogenförmige Nachdrückwand mit sichelförmigem Nachdrücker angeordnet ist, der das zu zerkleinernde Material zum Rotor bzw. zum Gegenmesser schiebt.This object is achieved according to the invention in a shredding device with the named genus solved in that an arcuate pressure wall with Sickle-shaped presser is arranged, the material to be shredded Pushes rotor or counter knife.

Erfindungsgemäß wird der sprunghafte Fortschritt einer etwa 20 %-igen Mehrleistung gegenüber den horizontalen Nachdrückern des Standes der Technik erreicht. According to the invention, the rapid progress of an approximately 20% increase in performance compared to the horizontal pressers of the prior art.

Nach einer bevorzugten Ausführungsform weist die bogenförmige Nachdrückwand vorzugsweise an ihrem unteren Endbereich eine Ausklappvorrichtung in Gestalt einer ausschwenkbaren Gehäusewand auf. Diese Ausklappvorrichtung wird vorzugsweise mechanisch-hydraulisch betätigt. Diese Ausklappvorrichtung bewirkt fortschrittlicherweise, dass unzerkleinerbare Fremdkörper bei Blockierung des Rotors entnommen werden können.
Bei den Zerkleinerungsvorrichtungen des Standes der Technik musste bei entsprechenden Situationen der Trichter bzw. der Füllraum entleert werden, wobei eine Bedienungsperson in den Raum einsteigen musste, was, wie die Praxis gezeigt hat, sehr problematisch und mit grosser Unfallgefahr verbunden war.
Das Wesen vorliegender Erfindung ist weiterhin der beiliegenden Zeichnung 1(= Figur 1) zu entnehmen.According to a preferred embodiment, the arch-shaped pressing wall preferably has a fold-out device in the form of a pivotable housing wall at its lower end region. This fold-out device is preferably operated mechanically-hydraulically. Progressively, this fold-out device has the effect that uncrushable foreign bodies can be removed when the rotor is blocked.
In the shredding devices of the prior art, the hopper or the filling chamber had to be emptied in corresponding situations, an operator having to enter the room, which, as practice has shown, was very problematic and associated with a great risk of accidents.
The essence of the present invention can also be seen in the accompanying drawing 1 (= FIG. 1).

Mit der Bezugsziffer 1 ist der Messerrotor, mit 2 ein nachstellbares Gegenmesser, mit 3 ein nachstellbares Nachschnittmesser, mit 4 ein Sieb, mit 5 eine bogenförmige Nachdrückwand, mit 5aa eine bogenförmige Ausklappvorrichtung in Gestalt einer ausschwenkbaren Gehäusewand, mit 6 ein sichelförmiger Nachdrücker, mit 7 ein Füllraum und mit 8 ein Auslauf für das zerkleinerte Material bezeichnet. Mit 5b ist die Gegenwand bezeichnet. In der Figur 1 ist beispielhaft eine bevorzugte Ausführung der vorliegenden Erfindung dargestellt. With the reference number 1 the knife rotor, with 2 an adjustable counter knife, with 3 an adjustable re-cutting knife, with 4 a sieve, with 5 an arched pressure wall, with 5aa an arcuate fold-out device in the form of a swing-out Housing wall, with 6 a crescent-shaped presser, with 7 a filling chamber and with 8 denotes an outlet for the shredded material. The counter wall is designated 5b. FIG. 1 shows an example of a preferred embodiment of the present invention shown.

Eine bevorzugte Ausführungsform wird im folgenden beschrieben.A preferred embodiment is described below.

Bei solchen Zerkleinerungsmaschinen mit einem genügend großen Rotor können auch Materialien, die in Ballen-Form vorliegen, beispielsweise Textilballen, in den Zerkleinerungsraum aufgegeben werden. Bekanntlich benötigt in Ballen-Form vorliegendes Material beim Antransport und bei der Lagerung wesentlich weniger Platz als in loser Form vorliegendes Material, es ist jedoch mit dem Nachteil behaftet, dass in ihm diverse nicht zerkleinerbare Fremdkörper enthalten sind, die bei der Aufgabe des Ballenmaterials in die Zerkleinerungsmaschine nicht feststellbar sind.In such crushing machines with a sufficiently large rotor can also Materials in the form of bales, such as textile bales, in the shredding room be abandoned. As is known, material in bale form is required much less space for transport and storage than in bulk present material, however, it has the disadvantage that it does not contain various Crushable foreign bodies are included in the task of the bale material in the Shredding machine are not detectable.

Die Nachteile dieses Standes der Technik werden durch vorliegende Erfindung unter Erreichung von Vorteilen, die weiter unten beschrieben werden, überwunden.The disadvantages of this prior art are highlighted by the present invention Achievement of benefits outlined below.

Das Ballenmaterial und naturgemäß gegebenenfalls daneben auch nicht in Ballen-Form vorliegendes zu zerkleinerndes Material gelangt selbständig zum Schnittvorgang und wird zerkleinert. Dabei werden feste und sperrige Teile durch Drehrichtungswechsel umgeschichtet und auf der gegenüberliegenden Seite der Zerkleinerungsmaschine ebenfalls weiter zerkleinert.The bale material and, of course, possibly also not in bale form existing material to be shredded automatically reaches the cutting process and is crushed. Fixed and bulky parts are shifted by changing the direction of rotation and also on the opposite side of the shredder further crushed.

Dabei garantiert ein eingebautes Sieb, welches in der Siebgröße auswechselbar ist, ein zerkleinertes Gut, beispielsweise ein Granulat in definierter Partikelgröße. A built-in sieve, which can be exchanged in the sieve size, guarantees one comminuted material, for example granules in a defined particle size.

In der Praxis ist es jedoch, wie oben bereits ausgeführt, unvermeidlich, daß im aufgegebenen Material und insbesondere im in Ballen-Form aufgegebenen Material diverse nicht zerkleinerbare Fremdkörper enthalten sind, die bei den Zerkleinerungsmaschinen des Standes der Technik nur mühsam durch Ausräumen des gesamten Zerkleinerungsraumes entfernt werden können.In practice, however, as stated above, it is inevitable that in the abandoned Material and especially in the material given in bale form diverse not Crushable foreign bodies are included, which are used in the shredding machines State of the art only laboriously by clearing out the entire comminution area can be removed.

Bei der erfindungsgemäßen Zerkleinerungsmaschine kann demgegenüber bei Erreichen eines eingestellten maximalen Moments, insbesondere Druckmoments, die Seitenwand mit Gegenmesseraufnahme aufklappen, so daß der Fremdkörper günstig ausgeschieden werden kann.In contrast, in the comminution machine according to the invention, when reached a set maximum torque, in particular pressure torque, the side wall open with counter knife receptacle so that the foreign body is expelled cheaply can be.

Die Einstellung dieses Moments kann entweder hydraulisch oder mechanisch erfolgen. Hierdurch wird eine sichere und schnelle Arbeitsweise im Betrieb erreicht.This torque can be set either hydraulically or mechanically. This ensures a safe and fast way of working in the company.
