Solche Zerkleinerungsmaschinen sind aus dem Stand der Technik, beispielsweise der EP 2 218 508 A1 , bekannt.Such crushers are known in the art, such as EP 2 218 508 A1 , known.

Figur 1 zeigt einen relevanten Ausschnitt einer solchen Zerkleinerungsvorrichtung 101 in einer Schnittdarstellung: Die Zerkleinerungsmaschine 101 umfasst ein Maschinengestell 104, an welchem ein Zerkleinerungsrotor 105 drehbar gelagert ist. Das mittels des Zerkleinerungsrotors 105 zu zerkleinernde Material wird der Zerkleinerungsmaschine 101 über einen Materialaufgaberaum 106 zugeführt, wobei der Materialaufgaberaum 106 beispielsweise durch Radlader, Gabelstapler oder Förderbänder manuell beschickt werden kann. Die Zerkleinerungsmaschine 101 umfasst weiterhin eine Zuführvorrichtung 120, welche schwenkbar am Maschinengestell 104 gelagert ist und mit welcher das zu zerkleinernde Material zum Zerkleinerungsrotor 105 beförderbar ist. Die Zuführvorrichtung 120 umfasst dabei einen Schwenkarm und einen Nachdrücker 121, welcher am freien Ende des Schwenkarms 122 angeordnet ist. Der Nachdrücker 121 weist eine Nachdrückfläche 133 und eine Unterseite 138 auf. Die Zuführvorrichtung 120 wird im Zerkleinerungsbetrieb entlang einer Nachdrückwand 126 geführt. Im unteren Bereich umfasst die Nachdrückwand 126 einen Wandabschnitt 107, der zu Wartungszwecken um eine Drehachse 108 mittels einer Kolben-Zylinder-Einheit 128 verschwenkbar ist. Dabei wird der Wandabschnitt 107 in den Materialaufgaberaum 106 hineingeschwenkt. Eine Bedienperson 134 erhält dadurch Zugang zu dem Zerkleinerungsrotor 105 und kann beispielsweise am Rotor 105 angeordnete Zerkleinerungsmesser auswechseln. FIG. 1 shows a relevant section of such a comminution device 101 in a sectional view: The comminution machine 101 comprises a machine frame 104, on which a crushing rotor 105 is rotatably mounted. The material to be comminuted by means of the comminution rotor 105 is fed to the comminution machine 101 via a material feed space 106, wherein the material feed space 106 can be manually fed, for example, by wheel loaders, forklifts or conveyor belts. The comminution machine 101 further comprises a feed device 120, which is mounted pivotably on the machine frame 104 and with which the material to be comminuted can be conveyed to the comminution rotor 105. The feeding device 120 in this case comprises a pivoting arm and a push-pull 121, which is arranged at the free end of the pivoting arm 122. The push-pull 121 has an impression surface 133 and a bottom 138. The feed device 120 is guided in the comminution operation along a push-back wall 126.

An operator 134 thereby obtains access to the comminution rotor 105 and can, for example, exchange comminution knives arranged on the rotor 105.

Eine weitere typische Wartungstätigkeit besteht darin, den Maschineninnenraum zu reinigen. Dies ist bei der in der Figur 1 dargestellten Zerkleinerungsmaschine 101 durch ein Verschwenken des Wandabschnitts 107 nur bereichsweise möglich. Insbesondere erfordert eine umfangreiche Reinigung im Bereich der Zuführvorrichtung 120 eine aufwändige Demontage einzelner Bauelemente, wie zum Beispiel von Hydraulikzylindern, welche die Zuführvorrichtung 120 bewegen, oder von der Kolben-Zylinder-Einheit 128, welche den Wandabschnitt 107 bewegt.Another typical maintenance activity is to clean the machine interior. This is when in the FIG. 1 shown crusher 101 by pivoting the wall portion 107 only partially possible. In particular, extensive cleaning in the area of the feeder 120 requires expensive disassembly of individual components, such as hydraulic cylinders moving the feeder 120, or the piston-cylinder unit 128 moving the wall portion 107.

Ein weiterer Nachteil des in Figur 1 dargestellten Stands der Technik besteht darin, dass bei einem Verklemmen der Zuführvorrichtung 120 im Bereich des Wandelements 107 dieses Wandelement 107 nicht geöffnet werden kann, um die Verklemmung zu beheben. Nur durch eine aufwendige Demontage von Teilen oder der gesamten Einheit ist eine solche Blockade der Zuführvorrichtung beseitigbar.Another disadvantage of in FIG. 1 In the case of a jamming of the feed device 120 in the region of the wall element 107, this wall element 107 can not be opened in order to eliminate the jamming. Only by a costly disassembly of parts or the entire unit such a blockage of the feeder can be eliminated.

Und schließlich besteht ein Nachteil darin, dass die bei einem Wechsel von einer Art von zu zerkleinerndem Material auf eine andere, davon abweichende Art von zu zerkleinerndem Material erforderliche Beseitigung des im Materialaufgaberaums verbleibenden Restmaterial nur bei einem geschlossenen Wandabschnitt 107 und durch einen Einstieg von vorne oder oben in den Materialaufgaberaum 106 möglich ist, da ein großer Teil des Restmaterials bei einem geöffneten Wandabschnitt 107 oberhalb des Wandabschnitts 107 zu liegen kommt und somit für den Maschinenbediener in der dargestellten Position nicht zugänglich ist.Finally, there is a disadvantage in that the elimination of the residual material remaining in the material feed room when changing from one type of material to be comminuted to another different type of material to be comminuted is only possible with a closed wall section 107 and through an entry from the front or the top of the material supply space 106 is possible because a large part of the residual material at an open wall portion 107 above the wall portion 107 comes to rest and thus is not accessible to the operator in the position shown.

In der EP 2 857 101 A1 wird eine Lösung beschrieben, bei welcher der Versuch unternommen wird, einen Teil der beschriebenen Nachteile zu beheben, indem der Wandabschnitt um eine vom Ende versetzte Drehachse verschwenkbar gelagert ist. Bei einer Verschwenkung um diese Drehachse werden gleichzeitig eine obere Öffnung, welche Zugang zur Zuführvorrichtung ermöglicht, und eine untere Öffnung, welche einen Zugang zum Rotor ermöglicht, freigegeben.In the EP 2 857 101 A1 describes a solution in which the attempt is made to remedy a part of the disadvantages described by the wall portion is pivotally mounted about an offset from the end axis of rotation. When pivoting about this axis of rotation at the same time an upper opening, which allows access to the feeder, and a lower opening, which allows access to the rotor, released.

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 EP 2 857 101 A1 offenbarten Lösung besteht darin, dass der Zugang zur oberen Öffnung, das heißt der Zugang zur Zuführvorrichtung, nur sehr umständlich möglich ist: Eine Bedienperson muss hierzu auf ein Podest oder eine Leiter klettern und den ihr entgegen ragenden Teilabschnitt der Wartungsklappe überbrücken. Der Handlungsspielraum der Bedienperson ist hierdurch stark eingeschränkt.Another disadvantage of in the EP 2 857 101 A1 disclosed solution is that the access to the upper opening, that is the access to the feeder, only very cumbersome possible: An operator must climb to a pedestal or a ladder and bridge the projecting her counterpart section of the service door. The room for maneuver of the operator is severely limited.

Die objektive technische Aufgabe der vorliegenden Erfindung besteht also darin, eine Zerkleinerungsmaschine gemäß dem Oberbegriff des Anspruchs 1 anzugeben, bei welcher die Nachteile des Stands der Technik vermieden werden und bei welcher insbesondere eine schnelle und unaufwändige Wartung durch eine Bedienperson möglich ist.The objective technical object of the present invention is therefore to provide a crushing machine according to the preamble of claim 1, in which the disadvantages of the prior art are avoided and in which in particular a quick and inexpensive maintenance by an operator is possible.

Diese Aufgabe wird gelöst durch die Merkmale des unabhängigen Anspruchs 1.This object is achieved by the features of independent claim 1.

Es ist also erfindungsgemäß vorgesehen, dass die Drehachse lösbar verriegelbar ausgebildet ist, neben dieser ersten Drehachse zumindest eine zweite lösbar verriegelbare Drehachse vorgesehen ist, und der wenigstens eine Wandabschnitt des Materialaufgaberaums im Wartungsbetrieb der Zerkleinerungsmaschine wahlweise um die erste oder die zumindest eine zweite Drehachse verschwenkbar ist.It is therefore provided according to the invention that the axis of rotation is detachably lockable, next to this first axis of rotation at least a second releasably lockable axis of rotation is provided, and the at least one wall portion of the material supply space in the maintenance mode of the crushing machine is selectively pivotable about the first or the at least one second axis of rotation ,

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 in 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.

Vorteilhafte Ausführungsformen der erfindungsgemäßen Zerkleinerungsmaschine sind in den abhängigen Ansprüchen definiert.Advantageous embodiments of the shredding machine according to the invention are defined in the dependent claims.

Die in den Figuren 2 bis 4 dargestellte Zerkleinerungsmaschine 1 dient dem Zerkleinern von Material, insbesondere von Wertstoffen, Restholz und Datenträger, wobei unter dem Terminus Datenträger beispielsweise Akten oder beschriebene CD's zu verstehen sind.The in the FIGS. 2 to 4 Shredder 1 shown serves for the comminution of material, in particular valuable materials, waste wood and data carriers, wherein the term data carrier means, for example, files or CD's to be described.

Die Zerkleinerungsmaschine 1 umfasst ein Maschinengestell 4. An diesem Maschinengestell 4 ist ein Zerkleinerungsrotor 5 um eine Drehachse 14 drehbar gelagert. Anstelle eines Zerkleinerungsrotors können auch mehrere Zerkleinerungsrotoren vorgesehen sein. An dem Zerkleinerungsrotor 5 sind beispielsweise Reißhaken oder Messer angeordnet, die mit einer konkav geschliffenen Rundschneidkrone versehen sein können. 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 comminution machine 1 comprises a machine frame 4. A comminution rotor 5 is rotatably mounted about a rotation axis 14 on this machine frame 4. Instead of a comminution rotor, several comminution rotors can also be provided. At the crushing rotor 5 zipper or knife are arranged, for example, which can be provided with a concave ground round cutting crown. The knives can be fastened by screw connections to knife carriers, which in turn can be welded into or screwed into the rotor milled knife pockets or screwed. The rotating knives work together to crush material with stationary, fixed counter knives. The counter knife can be designed in the form of Statormessern or Abstreifkämmen. Preferably, the counter blades 40 are fixedly connected to the machine frame 4. In order to bring about a relative movement between the knives arranged on the rotor 5 and the counter knives 40, the rotor 5 performs a rotational movement in a specific direction of rotation 17. In the illustrations, the rotational movement takes place counterclockwise. For rotation of the crushing rotor 5, a drive means, for example in the form of a torque motor is provided.

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 screening device 39, which determines the comminuting factor in accordance with the size of the sieve, and is conveyed further, for example with the aid of a conveyor belt, a transport screw, a chain conveyor or an extraction system.

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 Figuren 2 bis 8 dargestellt ist. Auf den Materialaufgaberaum 6 kann auch noch ein Einfülltrichter aufgesetzt sein.To the crushing rotor 5, the material to be crushed passes through a material feed space 6, which is limited in the case shown by a front wall 25, disposed on the other side of the crushing rotor 5 rear wall 26 and two side walls 27, due to the Darstellungsart only one of these two side walls 27 in the FIGS. 2 to 8 is shown. On the material supply chamber 6 can also be placed a hopper.

Bereichsweise wird die Zerkleinerungsmaschine 1 nach außen hin durch ein Gehäuse 32 abgeschirmt.In areas, the crusher 1 is shielded from the outside by a housing 32.

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 machine 1 further comprises a feeding device 20, which is pivotally mounted on the machine frame 4 and with which the material to be crushed to the crushing rotor 5 is conveyed. The pivoting movement of the feed device 20 takes place about a rotation axis 41. This is aligned substantially parallel to the axis of rotation 14 of the crushing rotor 5. The feeder 20 has a wedge-shaped push-pull 21, with a Nachdrückfläche 33 facing the crushing rotor 5, which may be formed, for example, substantially planar or concave curved. By a pivoting movement of the feeding device 20, material which is located between the pressing surface 33 and the comminuting rotor 5 is pushed in the direction of the comminution rotor 5. The pusher 21 also has a lower side 38, which faces the rear wall 26 of the material feed space 6. The feeding device 20 further comprises at least one, preferably two spaced-apart pivot arms 22, the pivot arms 22 each having a first end 23 and a second end 24, and wherein the feeding device 20 is mounted on the first frame 23 on the machine frame 4 and the second free end 24 of the follower 21 is arranged. In an advantageous embodiment of the feeding device 20, the two mutually parallel pivot arms 22 and arranged thereon follower 21 form a substantially U-shape.

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 feed device 20 via a driven shaft, wherein the drivable shaft may be connected to a lever mechanism as part of a arranged outside of the material feed space 6 drive device. Such an arrangement of the lever mechanism outside the material feed space 6 has the advantage that the lever mechanism is not affected by the material to be shredded. Otherwise, it would be conceivable that a linkage encompassed by the lever mechanism would be disturbed or even partly blocked if it were installed inside the material feed space 6. A hydraulic cylinder or pneumatic cylinder may be connected to the lever mechanism and configured to drive the lever mechanism. Such cylinders provide reliable, relatively inexpensive and easy to maintain or exchangeable drive means. Alternatively, at least one motor drive, in particular a servo motor or a torque motor for driving the shaft can be provided.

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 comminution machine 1 further comprises a wall section 7, which is stationary in the comminution operation of the comminution machine 1 and via which the material to be comminuted can be fed to the comminution rotor 5. The wall section 7 is in the maintenance mode of the crushing machine 1 either to a first releasably lockable axis of rotation 8 or a second releasably lockable axis of rotation 9 pivotally.

In der Figur 2 gestrichelt eingezeichnet ist die Stellung des Wandabschnitts 7 im Zerkleinerungsbetrieb. In diesem Fall sind beide Drehachsen 8 und 9 verriegelt. Der Nachdrücker 21 der Zuführvorrichtung 20 bewegt sich im Zerkleinerungsbetrieb entlang des Wandabschnitts 7 auf den Zerkleinerungsrotor 5 zu bzw. von dem Zerkleinerungsrotor 5 weg.In the FIG. 2 Dashed lines indicate the position of the wall section 7 in the comminuting operation. In this case, both axes of rotation 8 and 9 are locked. The replenisher 21 of the feeding device 20 moves in the crushing operation along the wall portion 7 on the crushing rotor 5 to and from the crushing rotor 5 away.

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 feeder 20 and the wall portion 7, the crushing machine 1 can be maintained in a maintenance operation. For this purpose, the wall portion 7 can be pivoted either about the first axis of rotation 8 or about the second axis of rotation 9. In this case, the axis of rotation 8 or 9, about which the wall portion 7 is pivoted, locked and at the same time the other, non-active axis of rotation 9 and 8 solved.

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 Figur 3 dargestellt. In dieser Stellung des Wandabschnitts 7 kann eine Bedienperson ohne Probleme von unten bereichsweise in den Materialaufgaberaum 6 hinein und an den Zerkleinerungsrotor 5 herantreten. Dadurch kann die Betriebsperson Wartungsarbeiten am Zerkleinerungsrotor 5 durchführen und in diesem Bereich des Materialaufgaberaums 6 Restmaterial, beispielsweise vor einem Materialwechsel, manuell entfernen.When the wall section 7 is pivoted about the first axis of rotation 8, the wall section 7 is moved into the material feed space 6 starting from the position in the comminution mode. He thereby releases a first opening 18 with access to the crushing rotor 5. The final position after this pivoting movement is separate in the FIG. 3 shown. In this position of the wall section 7, an operator without problems from below in some areas in the material feed space 6 and zoom in on the crushing rotor 5. As a result, the operator can carry out maintenance work on the comminuting rotor 5 and manually remove residual material, for example before a material change, in this area of the material feed space 6.

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 Figur 4 gesondert dargestellt. In dieser Schwenkstellung des Wandabschnitts 7 hat eine Bedienperson 34 freien Zugang zur Zuführvorrichtung 20 und insbesondere zur Nachdrückeinheit 21. Dabei kann die Zuführvorrichtung 20 in eine beliebige und zur Durchführung der anstehenden Wartungsarbeit günstige Stellung gebracht werden. Eine mögliche Verklemmung von Material zwischen dem Nachdrücker 21 und dem Wandabschnitt 7 kann in einfacher Weise durch ein Wegschwenken des Wandabschnitts 7 um die zweite Drehachse 9 behoben werden.When the wall section 7 is pivoted about the second axis of rotation 9, the wall section 7 is moved away from the material supply chamber 6. The end position, which occupies the wall portion 7 after this pivoting movement is in the FIG. 4 shown separately. In this pivoting position of the wall portion 7, an operator 34 has free access to the feeder 20 and in particular to the Nachdrückeinheit 21. In this case, the feeder 20 can be placed in any favorable and to carry out the upcoming maintenance work position. A possible jamming of material between the presser 21 and the wall section 7 can be remedied in a simple manner by pivoting away the wall section 7 about the second axis of rotation 9.

Zur Überführung des Wandabschnitts 7 von der Stellung, welche der Wandabschnitt 7 im Zerkleinerungsbetrieb einnimmt, in die beiden in den Figuren 3 und 4 dargestellten Schwenkstellungen, ist eine Verstellvorrichtung 28, beispielsweise in Form einer hydraulischen Kolben-Zylinder-Einheit vorgesehen, welche sich einerseits über eine Lagestelle 29 am Maschinengestell 4 abstützt und andererseits über eine Angriffsstelle 30 mit dem Wandabschnitt 7 verbunden ist.For transferring the wall section 7 from the position which occupies the wall section 7 in the crushing operation, in the two in the Figures 3 and 4 illustrated pivoting positions, an adjusting device 28, for example in the form of a hydraulic piston-cylinder unit is provided which is supported on the one hand via a positioning point 29 on the machine frame 4 and on the other hand connected via an engagement point 30 with the wall portion 7.

In alternativen Ausführungsformen kann die Verstellvorrichtung 28 auch über elektrische Stelleinheiten oder Hebelmechaniken oder aus Kombinationen hiervon realisiert sein.In alternative embodiments, the adjustment device 28 may also be realized via electrical actuators or lever mechanisms or combinations thereof.

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 bearing point 29 and to connect the piston to the point of engagement 30 of the wall portion 7. In the case shown, the point of attack 30 is formed as a relative to the wall portion 7 angled lever piece.

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 adjustment device 28 is advantageously arranged on the machine frame 4 with respect to the first and second rotation axes 8 and 9 such that the adjustment device 28 both for pivoting the wall portion 7 about the first axis of rotation 8 and for giving the wall portion 7 about the second axis of rotation 9, each starting from the position in the crushing operation in the same direction 31 - relative to the bearing point 29 on the machine frame 4 - directed adjustment must perform. In the case of a piston-cylinder unit is directed in each case in the same direction stroke movement of the cylinder.

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 device 28 in all positions of the wall portion 7 at a pivoting about the first and second rotation axis 8 and 9 and in Mounting position of the crushing machine 1 completely or for the most part below the respective active axis of rotation 8 and 9 respectively. This configuration is advantageous because it can be avoided in a pivoting of the wall portion 7 that 6 material falling out of the material supply chamber 6 reaches the adjustment device 28 and this may be damaged. Rather, the adjusting device 28 is protected by the wall portion 7 against falling material.

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 rotation 8 and 9 are aligned substantially parallel to each other and substantially parallel to the axis of rotation 14 of the comminuting motor 5, and the first axis of rotation 8 in mounting position of the crushing machine 1 above the second axis of rotation 9 is arranged, and the first axis of rotation 8 at a first end 15 of the wall portion 7 and the second axis of rotation 9 is disposed at a second end 16 of the wall portion 7, and the second axis of rotation 9 is disposed immediately adjacent to the comminution rotor 5. In contrast, the first axis of rotation 8 has a greater distance from the comminuting rotor 5.

Zur Überführung des Wandabschnitts 7 in die in den Figuren 3 und 4 dargestellten Stellungen - ausgehend von der Stellung im Zerkleinerungsbetrieb - wird der Wandabschnitt 7 jeweils in Rotationsrichtung 17 des Zerkleinerungsrotors 5 bewegt, in der dargestellten Ansicht also jeweils gegen den Uhrzeigersinn um die jeweils aktive Drehachse 8 bzw. 9.To transfer the wall section 7 in the in the Figures 3 and 4 shown positions - starting from the position in the crushing operation - the wall portion 7 is respectively moved in the direction of rotation 17 of the crushing rotor 5, in the view shown in each case counterclockwise about the respective active axis of rotation 8 and 9 respectively.

Der Wandabschnitt 7 bildet ca. 80% der Rückwand 26 des Materialaufgaberaums 6.The wall section 7 forms approximately 80% of the rear wall 26 of the material feed space 6.

Die in der Figur 5 dargestellte Zerkleinerungsmaschine 2 weist im Vergleich zu der in den Figuren 2 bis 4 dargestellten Zerkleinerungsmaschine keine Zuführvorrichtung 20 auf. Die Notwendigkeit für eine solche Zuführvorrichtung 20 ist nämlich nicht in allen Fällen gegeben, insbesondere dann nicht, wenn es sich bei dem zu zerkleinernden Material um kleinteiliges und schweres Material handelt, welches ohnehin aufgrund der Schwerkraft in Richtung des Zerkleinerungsrotors 5 rutscht.The in the FIG. 5 shown crushing machine 2 has in comparison to that in the FIGS. 2 to 4 Crusher shown no feeder 20 on. The need for such a feeding device 20 is in fact not given in all cases, especially not when it is the material to be crushed small-sized and heavy material, which slips in the direction of the crushing rotor 5 anyway due to gravity.

Die in den Figuren 6 bis 8 dargestellte Zerkleinerungsvorrichtung 3 unterscheidet sich von den in den Figuren 2 bis 4 bzw. 5 dargestellten Zerkleinerungsvorrichtungen 1 bzw. 2 dadurch, dass 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 3 vollständig oder zum überwiegende Teil nicht unter, sondern oberhalb der jeweils aktiven Drehachse 8 bzw. 9 angeordnet ist. Ansonsten entspricht die Darstellung der Figur 6 der Darstellung der Figur 2, die Darstellung der Figur 7 der Darstellung der Figur 3 und die Darstellung der Figur 8 der Darstellung der Figur 4.The in the FIGS. 6 to 8 shown crushing device 3 differs from those in the FIGS. 2 to 4 or 5 illustrated crushing devices 1 and 2 characterized in that the adjusting device 28 in all positions of the wall portion 7 at a pivoting about the first and second axis of rotation 8 and 9 and in mounting position of the crushing machine 3 completely or for the most part not below, but is arranged above the respective active axis of rotation 8 and 9 respectively. Otherwise the representation corresponds to the FIG. 6 the representation of FIG. 2 , the representation of FIG. 7 the representation of FIG. 3 and the representation of FIG. 8 the representation of FIG. 4 ,

Die Figuren 9a bis 9c dienen der Veranschaulichung einerseits des Zerkleinerungsbetriebs 35 und andererseits des Wartungsbetriebs 36 bzw. 37:The FIGS. 9a to 9c serve to illustrate on the one hand the crushing operation 35 and on the other hand the maintenance operation 36 or 37:

Der Wandabschnitt 7 ist über vier lösbar verriegelbare Lagerstellen 10, 11, 12 und 13 mit den Maschinengestell 4 verbunden, wobei ein erstes Paar 10 und 11 der vier Lagerstellen die erste, obere Drehachse 8 und ein zweites Paar 12 und 13 der vier Lagerstellen die zweite, untere Drehachse 9 definieren. Im Zerkleinerungsbetrieb 35 sind alle Lagerstellen 10, 11, 12 und 13 verriegelt, das bedeutet, dass der Wandabschnitt 7 feststehend ausgebildet ist.The wall portion 7 is connected via four releasably lockable bearings 10, 11, 12 and 13 to the machine frame 4, wherein a first pair 10 and 11 of the four bearing points, the first, upper axis of rotation 8 and a second pair 12 and 13 of the four bearing points, the second , define lower axis of rotation 9. In the crushing operation 35 all bearings 10, 11, 12 and 13 are locked, which means that the wall portion 7 is formed stationary.

Im Wartungsbetrieb 36 bzw. 37 kann der Wandabschnitt 7 nun einerseits um die erste Drehachse 8 verschwenkt werden oder andererseits um die zweite Drehachse 9. Hierzu ist die erste Drehachse 8 bzw. die zweite Drehachse 9 verriegelt und die nicht aktive, andere Drehachse 9 bzw. 8 gelöst.In the maintenance operation 36 or 37, the wall section 7 can now be pivoted on the one hand about the first axis of rotation 8 or on the other hand about the second axis of rotation 9. For this purpose, the first axis of rotation 8 and the second axis of rotation 9 is locked and the non-active, other axis of rotation 9 and 8 solved.

Die lösbare Verriegelung kann technisch durch eine mechanische, hydraulische oder elektrische Verriegelung gelöst sein. Hierzu kann an jeder der vier Lagerstellen 10, 11, 12 und 13 ein am Maschinengestell 4 gelagerter Bolzen vorgesehen sein, der zwischen einer Stellung, in welcher er in den Wandabschnitt 7 eingreift, und einer Stellung, in welcher er nicht in Eingriff mit dem Wandabschnitt 7 steht, verschiebbar ist.The releasable lock can be solved technically by a mechanical, hydraulic or electrical locking. For this purpose, at each of the four bearing points 10, 11, 12 and 13, a bolt mounted on the machine frame 4 can be provided, which intervenes between a position in which it engages in the wall section 7 and a position in which it is not in engagement with the wall section 7 is, is displaceable.
