Nachteilig bei dieser Lösung ist allerdings immer noch die Tatsache, dass sich bei einer Verklemmung der Zuführvorrichtung im Bereich der Drehachse die Wartungsklappe in manchen Fällen erst gar nicht öffnen lässt. In diesem Fall muss die Zuführvorrichtung nach wie vor demontiert werden, um die Verklemmung beheben zu können.A disadvantage of this solution, however, is still the fact that in a jamming of the feeder in the region of the axis of rotation, the service flap in some cases can not even open. In this case, the Feeding device are still dismantled to fix the deadlock.
Ein weiterer Nachteil der in der

Dadurch dass der wenigstens eine Wandabschnitt des Materialaufgaberaums im Wartungsbetrieb der Zerkleinerungsmaschine wahlweise um die erste oder die zumindest eine zweite Drehachse verschwenkbar ist, können unterschiedliche Bereiche des Materialaufgaberaums für Wartungsarbeiten zugänglich gemacht werden und zwar auch dann, wenn die Zerkleinerungsmaschine eine Zuführvorrichtung umfasst und sich diese im Bereich des wenigstens einen Wandabschnitts verklemmt hat. Die wahlweise Schwenkbarkeit um die erste und die zumindest eine zweite Drehachse schafft nämlich die Voraussetzung dafür, dass der wenigstens eine Wandabschnitt auch von dem Materialaufgaberaum und damit der Zuführvorrichtung weg bewegbar ist. Gleichzeitig kann die Zuführvorrichtung zu Wartungszwecken in jede beliebige Stellung gebracht werden, ohne dass eine in den Materialaufgaberaum hinein stehende Wartungsklappe im Weg wäre.By virtue of the fact that the at least one wall section of the material feed space is optionally pivotable about the first or the at least one second axis of rotation during maintenance operation of the shredding machine, different areas of the material feed area can be made accessible for maintenance, even if the shredding machine comprises a feed device and these are in the Area of at least one wall portion has jammed. The optional pivoting about the first and the at least one second axis of rotation provides namely the prerequisite that the at least one wall portion is also movable away from the material supply space and thus the feeding device. At the same time, the feeder can be used for maintenance purposes Any position can be brought without a standing in the material input space maintenance flap in the way.
Eine Demontage von Hebeln, Hydraulikzylindern oder anderweitigen Maschinenkomponenten ist zur vollständigen Wartung der Zerkleinerungsmaschine und zur Behebung typischer Betriebsstörungen nicht mehr notwendig. Auch eine vollständige Entleerung des Materialaufgaberaums, um das nachfolgend zu verarbeitende Material sortenrein verarbeiten zu können, ist problemlos möglich, ohne dass sich hierzu eine Bedienperson in eine ungünstige Position bewegen müsste.Dismantling levers, hydraulic cylinders or other machine components is no longer necessary to fully service the shredder and to resolve typical malfunctions. Even a complete emptying of the material supply space to process the material to be processed below sorted, is easily possible without this would have to move an operator in an unfavorable position.

Die Messer können durch Verschraubungen an Messerträgern befestigt sein, die wiederum in bzw. an in den Rotor gefrästen Messertaschen eingeschweißt oder angeschraubt sein können. Die rotierenden Messer wirken zur Zerkleinerung von Material mit stationären, feststehenden Gegenmessern zusammen. Die Gegenmesser können in Form von Statormessern oder Abstreifkämmen ausgebildet sein. Bevorzugt sind die Gegenmesser 40 fest mit dem Maschinengestell 4 verbunden. Zur Herbeiführung einer Relativbewegung zwischen den am Rotor 5 angeordneten Messern und den Gegenmessern 40 führt der Rotor 5 eine Rotationsbewegung in eine bestimmte Rotationsrichtung 17 durch. In den Darstellungen erfolgt die Rotationsbewegung gegen den Urzeigersinn. Zur Rotation des Zerkleinerungsrotors 5 ist ein Antriebsmittel, beispielsweise in Form eines Torquemotors vorgesehen.The
Das zwischen den rotierenden Messern und den Gegenmessern zerkleinerte Material wird in weiterer Folge durch eine Siebeinrichtung 39, welche den Zerkleinerungsfaktor nach Maßgabe der Siebgröße bestimmt, ausgetragen und zum Beispiel mit Hilfe eines Transportbandes, einer Transportschnecke, eines Kettenförderers oder einer Absauganlage weiterbefördert.The material comminuted between the rotating knives and the counter knives is subsequently discharged through a
Zu dem Zerkleinerungsrotor 5 gelangt das zu zerkleinernde Material über einen Materialaufgaberaum 6, der im dargestellten Fall durch eine Vorderwand 25, eine auf der anderen Seite des Zerkleinerungsrotors 5 angeordnete Rückwand 26 sowie zwei Seitenwände 27 begrenzt ist, wobei aufgrund der Darstellungsart nur eine dieser beiden Seitenwände 27 in den
Bereichsweise wird die Zerkleinerungsmaschine 1 nach außen hin durch ein Gehäuse 32 abgeschirmt.In areas, the
Die Zerkleinerungsmaschine 1 umfasst weiterhin eine Zuführvorrichtung 20, welche schwenkbar am Maschinengestell 4 gelagert ist und mit welcher das zu zerkleinernde Material zum Zerkleinerungsrotor 5 beförderbar ist. Die Schwenkbewegung der Zuführvorrichtung 20 erfolgt dabei um eine Drehachse 41. Diese ist im Wesentlichen parallel zur Drehachse 14 des Zerkleinerungsrotors 5 ausgerichtet. Die Zuführvorrichtung 20 weist einen keilförmigen Nachdrücker 21 auf, mit einer dem Zerkleinerungsrotor 5 zugewandten Nachdrückfläche 33, die beispielsweise im Wesentlichen eben oder konkav gekrümmt ausgebildet sein kann. Durch eine Schwenkbewegung der Zuführvorrichtung 20 wird Material, welches sich zwischen der Nachdrückfläche 33 und dem Zerkleinerungsrotor 5 befindet, in Richtung des Zerkleinerungsrotors 5 geschoben. Der Nachdrücker 21 weist weiterhin eine Unterseite 38 auf, welche der Rückwand 26 des Materialaufgaberaums 6 zugewandt ist. Die Zuführvorrichtung 20 weist weiterhin wenigstens einen, vorzugsweise zwei voneinander beabstandete Schwenkarme 22 auf, wobei die Schwenkarme 22 jeweils ein erstes Ende 23 und ein zweites Ende 24 umfassen, und wobei die Zuführvorrichtung 20 über das erste Ende 23 am Maschinengestell 4 gelagert ist und am zweiten freien Ende 24 der Nachdrücker 21 angeordnet ist. In einer vorteilhaften Ausgestaltung der Zuführvorrichtung 20 bilden die zwei parallel zueinander angeordneten Schwenkarme 22 und der daran angeordnete Nachdrücker 21 im Wesentlichen eine U-Form aus.The crushing
Der Antrieb der Zuführvorrichtung 20 erfolgt über eine antreibbare Welle, wobei die antreibbare Welle mit einem Hebelmechanismus als Teil einer außerhalb des Materialaufgaberaums 6 angeordneten Antriebsvorrichtung verbunden sein kann. Eine solche Anordnung des Hebelmechanismus außerhalb des Materialaufgaberaums 6 hat den Vorteil, dass der Hebelmechanismus nicht durch das zu zerkleinernde Material beeinträchtigt wird. Andernfalls wäre es denkbar, dass ein von dem Hebelmechanismus umfasstes Gestänge gestört oder gar zum Teil blockiert wird, wenn es innerhalb des Materialaufgaberaums 6 verbaut wäre. Ein Hydraulikzylinder oder Pneumatikzylinder kann mit dem Hebelmechanismus verbunden und dazu ausgebildet sein, den Hebelmechanismus anzutreiben. Solche Zylinder stellen zuverlässige, relativ kostengünstige und einfach zu wartende bzw. austauschbare Antriebsmittel dar. Alternativ kann zumindest ein motorischer Antrieb, insbesondere ein Stellmotor oder ein Torquemotor zum Antreiben der Welle vorgesehen sein.The drive of the
Die Zerkleinerungsmaschine 1 umfasst weiterhin einen Wandabschnitt 7, welcher im Zerkleinerungsbetrieb der Zerkleinerungsmaschine 1 feststehend ausgebildet ist und über welchen das zu zerkleinernde Material dem Zerkleinerungsrotor 5 zuführbar ist. Der Wandabschnitt 7 ist im Wartungsbetrieb der Zerkleinerungsmaschine 1 wahlweise um eine erste lösbar verriegelbare Drehachse 8 oder eine zweite lösbar verriegelbare Drehachse 9 verschwenkbar.The
In der
Zur Durchführung von Wartungsarbeiten bzw. zur Behebung von Betriebsstörungen, wie zum Beispiel Verklemmungen von Material zwischen der Zuführvorrichtung 20 und dem Wandabschnitt 7, kann die Zerkleinerungsmaschine 1 in einem Wartungsbetrieb gewartet werden. Hierzu kann der Wandabschnitt 7 entweder um die erste Drehachse 8 oder um die zweite Drehachse 9 verschwenkt werden. Dabei ist die Drehachse 8 bzw. 9, um welche der Wandabschnitt 7 verschwenkt wird, verriegelt und gleichzeitig die andere, nicht aktive Drehachse 9 bzw. 8 gelöst.In order to perform maintenance or to remedy malfunctions, such as jamming of material between the
Bei einer Verschwenkung des Wandabschnitts 7 um die erste Drehachse 8 wird der Wandabschnitt 7 ausgehend von der Stellung im Zerkleinerungsbetrieb in den Materialaufgaberaum 6 hineinbewegt. Er gibt hierdurch eine erste Öffnung 18 mit Zugang zum Zerkleinerungsrotor 5 frei. Die Endposition nach dieser Verschwenkbewegung ist gesondert in der
Bei einer Verschwenkung des Wandabschnitts 7 um die zweite Drehachse 9 wird der Wandabschnitt 7 von dem Materialaufgaberaum 6 weg bewegt. Die Endstellung, welche der Wandabschnitt 7 nach dieser Verschwenkbewegung einnimmt, ist in der
Zur Überführung des Wandabschnitts 7 von der Stellung, welche der Wandabschnitt 7 im Zerkleinerungsbetrieb einnimmt, in die beiden in den
In alternativen Ausführungsformen kann die Verstellvorrichtung 28 auch über elektrische Stelleinheiten oder Hebelmechaniken oder aus Kombinationen hiervon realisiert sein.In alternative embodiments, the
Im Fall einer Kolben-Zylinder-Einheit bietet es sich an, den Zylinder an der Lagerstelle 29 angreifen zu lassen und den Kolben mit der Angriffsstelle 30 des Wandabschnitts 7 zu verbinden. Im dargestellten Fall ist die Angriffsstelle 30 als ein gegenüber dem Wandabschnitt 7 abgewinkeltes Hebelstück ausgebildet.In the case of a piston-cylinder unit, it makes sense to let the cylinder engage the
Die Verstellvorrichtung 28 ist vorteilhafterweise derart am Maschinengestell 4 in Bezug auf die erste und zweite Drehachse 8 und 9 angeordnet, dass die Verstellvorrichtung 28 sowohl zum Verschwenken des Wandabschnitts 7 um die erste Drehachse 8 als auch zum Verschenken des Wandabschnitts 7 um die zweite Drehachse 9, jeweils ausgehend von der Stellung im Zerkleinerungsbetrieb eine in dieselbe Richtung 31 - bezogen auf die Lagerstelle 29 am Maschinengestell 4 - gerichtete Verstellbewegung ausführen muss. Im Falle einer Kolben-Zylinder-Einheit handelt es sich um eine jeweils in dieselbe Richtung gerichtet Hubbewegung des Zylinders.The
Weiterhin ist die Verstellvorrichtung 28 in allen Stellungen des Wandabschnitts 7 bei einer Verschwenkung um die erste bzw. zweite Drehachse 8 bzw. 9 und in Montagelage der Zerkleinerungsmaschine 1 vollständig oder zum überwiegenden Teil unterhalb der jeweils aktiven Drehachse 8 bzw. 9 angeordnet. Diese Konfiguration ist deshalb vorteilhaft, da hierdurch bei einer Verschwenkung des Wandabschnitts 7 vermieden werden kann, dass aus dem Materialaufgaberaum 6 herausfallendes Material zur Verstellvorrichtung 28 gelangt und diese möglicherweise beschädigt. Vielmehr wird die Verstellvorrichtung 28 durch den Wandabschnitt 7 gegen herabfallendes Material geschützt.Furthermore, the adjusting
Es sei noch darauf hingewiesen, dass in dem dargestellten Ausführungsbeispiel die beiden lösbar verriegelbaren Drehachsen 8 und 9 im Wesentlichen parallel zueinander und im Wesentlichen parallel zur Drehachse 14 des Zerkleinerungsmotors 5 ausgerichtet sind, und die erste Drehachse 8 in Montagelage der Zerkleinerungsmaschine 1 oberhalb der zweiten Drehachse 9 angeordnet ist, und die erste Drehachse 8 an einem ersten Ende 15 des Wandabschnitts 7 und die zweite Drehachse 9 an einem zweiten Ende 16 des Wandabschnitts 7 angeordnet ist, und die zweite Drehachse 9 unmittelbar benachbart zum Zerkleinerungsrotor 5 angeordnet ist. Demgegenüber weist die erste Drehachse 8 einen größeren Abstand zum Zerkleinerungsrotor 5 auf.It should be noted that in the illustrated embodiment, the two releasably lockable axes of
