Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Zerkleinern von Abfällen, insbesondere Holzabfällen, Restholzstücken od.dgl., bei welcher in einem Gehäuse ein mit Zerkleinerungswerkzeugen versehener Rotor horizontal gelagert und oberhalb des Rotors ein Aufgabetrichter vorgesehen ist, wobei das zu zerkleinernde Gut mittels einer quer zur Rotorachse wirksamen Andrückeinrichtung dem Rotor zuführbar ist.The invention relates to a device for shredding waste, in particular wood waste, residual wood pieces or the like, in which a rotor provided with shredding tools is mounted horizontally in a housing and a feed hopper is provided above the rotor, the material to be shredded by means of a cross to the rotor axis effective pressing device can be fed to the rotor.

Es sind bereits verschiedene Ausführungen dieser Art bekannt. Bei einer bekannten Ausbildung ist der Rotor im Gehäuse stillstehend angeordnet und der Aufgabetrichter oberhalb des Rotors verschiebbar, wobei der dem Rotor vorgelagerte Gehäusebereich vertikal verlaufende Seitenwände aufweist. Eine solche Ausbildung hat den Nachteil, daß die durch den Andrückschild zwischen den Gehäuseseitenwänden zum Rotor hingeschobenen Holzstücke zum Verspreizen neigen, wenn ein Holzstab nur unwesentlich länger als die Breite des Gehäuses ist und durch einseitigen Vorschub zwischen den beiden Seitenwänden verspreizt wird. Dies führt dann zu einem völligen Stillegen des Vorschubes, sodaß die Maschine angehalten und die Verklemmung behoben werden muß.Weiters ist auch nachteilig, daß eine große Masse zu bewegen ist, nämlich der mit zu zerkleinerndem Gut beladene Trichter, der über den Rotor hinweggeführt wird. Dies bedeutet, daß durch die Transporteinrichtungen, die den Trichter bewegen, nicht nur der Anpreßdruck erzeugt werden muß, sondern es muß auch das gesamte Gewicht des mit zu zerkleinerndem Gut befüllten Rotors bewegt werden, was zusätzlich noch spezieller Führungen und dgl. bedarf, in welchen es leicht zu einem Verklemmen der Restholzstücke kommen kann.Various designs of this type are already known. In a known embodiment, the rotor is arranged in a stationary manner in the housing and the feed hopper is displaceable above the rotor, the housing region in front of the rotor having vertically extending side walls. Such a design has the disadvantage that the pieces of wood pushed by the pressure plate between the housing side walls towards the rotor tend to spread when a wooden stick is only insignificantly longer than the width of the housing and is spread between the two side walls by one-sided feed. This then leads to a complete stoppage of the feed, so that the machine has to be stopped and the jamming must be remedied. Another disadvantage is that a large mass has to be moved, namely the hopper loaded with material to be shredded, which is guided over the rotor. This means that not only the contact pressure has to be generated by the transport devices which move the funnel, but also the entire weight of the rotor filled with material to be comminuted has to be moved, which additionally requires special guides and the like, in which the remaining pieces of wood can easily become jammed.

Bei einer anderen Ausbildung der eingangs genannten Art ist der Trichter feststehend angeordnet, wobei entlang der schrägen Trichterwandung das zu zerkleinernde Gut gegen den Rotor gepreßt wird. Diese Ausbildung ist vor allem zum Zerkleinern von leichtem Gut, wie Papierabfälle, Styroporabfälle u.dgl. vorgesehen, wobei auch die Rotorausbildung dementsprechend gewählt ist, sodaß diese Ausbildung für harte Abfälle, wie es Holzabfälle oder Restholzstücke sind, nicht geeignet ist.In another embodiment of the type mentioned in the introduction, the funnel is arranged to be stationary, the material to be shredded being pressed against the rotor along the oblique funnel wall. This training is especially for crushing light goods such as paper waste, polystyrene waste and the like. provided, the rotor design is selected accordingly, so that this training is not suitable for hard waste, such as wood waste or pieces of residual wood.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, welche im Betrieb möglichst störunanfällig ist.The invention has for its object to provide a device of the type mentioned, which is as prone to failure in operation.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß wenigstens die im Wirk- bzw. Bewegungsbereich der Andrückeinrichtung befindlichen Bereiche der in Vorschubrichtung der Anpreßplatte verlaufenden Seitenwandungen des Trichters nach oben hin schräg nach außen geneigt verlaufen. Dadurch wird ein Verspreizen von Holzstücken zwischen den in Vorschubrichtung der Anpreßplatte verlaufenden Seitenwandungen des Trichters vermieden, da bei Druckausübung auf ein längliches Holzstück, dessen Länge nur geringfügig größer als die gegenseitige Entfernung der Seitenwandungen ist, dieses Holzstück entlang der schrägen Fläche nach oben ausweichen kann.According to the invention, this object is achieved in that at least the areas of the side walls of the funnel running in the feed direction of the pressure plate, which areas are in the effective or moving range of the pressing device, are inclined upwards outwards. A spreading of pieces of wood between the side walls of the funnel running in the feed direction of the pressure plate is avoided, since when pressure is exerted on an elongated piece of wood, the length of which is only slightly greater than the mutual distance of the side walls, this piece of wood can dodge upwards along the inclined surface.

Vorteilhafterweise kann bei einer Ausbilödung, bei welcher der Rotor im Bereich der Trichterwandungen angeordnet ist und sich über die Länge der Trichterwandung erstreckt, in der dem Rotor gegenüberliegenden Trichterwandung eine über die gesamte Breite des Trichters reichende Durchbrechung vorgesehen sein, durch welche hindurch eine quer zum Rotor verlaufende Anpreßplatte in Richtung zum Rotor hin bzw. von jenem weg verschiebbar ist und wobei an der Rückseite der Anpreßplatte im Bereich der Oberkante derselben ein in Vorschubrichtung verlaufender Abdeckschild vom Rotor wegweisend angebracht ist. Dadurch wird lediglich in dem relativ schmalen Bereich des Rotors ein Anpreßdruck erzeugt, welcher ausreichend ist, daß aufgrund der Rotordrehung die Zerkleinerung erfolgt. Ein etwaiges Hineinreichen von größeren Holzteilen führt dazu, daß diese durch die Anpreßplatte solange aus der Bahn herausgepreßt werden, bis sie in die richtige Lage zum Anlagen an den Rotor kommen. Durch diese Maßnahmen und dadurch, daß der Druck nur im unteren Bereich erfolgt, wird einem Verklemmen der im Trichter befindlichen Holzstücke wirksam vorgebeugt. Außerdem wird mit geringen Vorschubkräften und geringen bewegten Teilen das Auslangen gefunden.In the case of a formation in which the rotor is arranged in the region of the funnel walls and extends over the length of the funnel wall, an opening extending across the entire width of the funnel, through which an opening transverse to the rotor passes, can be provided in the funnel wall opposite the rotor extending pressure plate in the direction of the rotor or is displaceable away from it and wherein on the back of the pressure plate in the region of the upper edge thereof a cover plate extending in the feed direction is attached pointing away from the rotor. As a result, a contact pressure is generated only in the relatively narrow area of the rotor, which is sufficient for comminution to take place due to the rotor rotation. Any handing in of larger wooden parts leads to them being pressed out of the web by the pressure plate until they come into the correct position to rest against the rotor. These measures and the fact that the pressure only takes place in the lower area effectively prevent jamming of the pieces of wood located in the funnel. In addition, with small feed forces and small moving parts, sufficiency is found.

Weiters können die in Vorschubrichtung der Anpreßplatte verlaufenden Seitenwandungen des Trichters zumindest bis in Höhe der Drehachse des Rotors nach oben hin schräg nach außen geneigt verlaufen. Dadurch wird erreicht, daß bei Aufbringung des Anpreßdruckes im Falle von Verklemmungen die Holzstücke nach oben hin ausweichen, wodurch dann dem Verklemmen von längeren Holzstücken vorgebeugt ist.Furthermore, the side walls of the funnel running in the feed direction of the pressure plate can be inclined upwards outwards at least up to the height of the axis of rotation of the rotor. This ensures that when the contact pressure is applied in the event of jamming the pieces of wood dodge upwards, which then prevents jamming of longer pieces of wood.

Bei einer besonders vorteilhaften Ausbildung kann die Anpreßplatte an dem dem Rotor zugewandten Ende eines oder mehrerer Druckstempel angebracht sein, deren anderes Ende an einem parallel zur Anpreßplatte verlaufenden Querbalken angreift, welcher die freien Enden zweier Schwenkhebel verbindet, wobei der bzw. die Druckstempeln kreisbogenförmig gekrümmt verlaufen und wobei der Bogenmittelpunkt mit dem Schwenkpunkt der Schwenkhebel zusammenfällt. Dadurch wird eine besonders platzsparende Ausbildung geschaffen, wobei aufgrund dieser Ausbildung nicht zuletzt aufgrund der gekrümmten Bodenfläche des Trichters einem Verklemmen von längeren und größeren zu zerkleinernden Stücken vorgebeugt wird. Außerdem benötigt die Schwenkvorrichtung, wie schon angedeutet, weniger Platz als eine geradlinige Druckeinrichtung, sodaß die Einrichtungen mit geringerer Grundfläche das Auslangen finden. Dabei kann für den Antrieb der Schwenkhebeln je eine hydraulische Kolben/Zylindereinheit vorgesehen sein, deren eines Ende am Schwenkhebel bzw. an einem Fortsatz desselben und deren anderes Ende am Rahmen angreift, wodurch erreicht wird, daß eine gleichmäßige Druckaufbringung über beide Schwenkhebel erfolgt, da aufgrund der gleichmäßigen Druckausbreitung eines flüssigen Mediums beide Zylinder die gleiche Druckkraft einbringen.In a particularly advantageous embodiment, the pressure plate can be attached to the end of one or more plungers facing the rotor, the other end of which engages a crossbar running parallel to the pressure plate, which connects the free ends of two pivot levers, the plunger or plugs being curved in a circular arc and the arc center coincides with the pivot point of the pivot levers. This creates a particularly space-saving design, whereby this jamming prevents longer and larger pieces to be shredded, not least because of the curved bottom surface of the funnel. In addition, as already indicated, the swiveling device takes up less space than a straight-line printing device, so that the devices with a smaller footprint find their end. A hydraulic piston / cylinder unit can be provided for driving the pivot levers, one end of which engages the pivot lever or an extension of the same and the other end of which engages the frame, thereby ensuring that pressure is applied uniformly over both pivot levers, because of: the uniform pressure distribution of a liquid medium both cylinders apply the same pressure.

Schließlich kann bei einer Ausbildung, bei welcher der Aufgabetrichter eine bis unter die Rotorachse reichende Andrückplatte aufweist, wobei der Rotor und der Aufgabetrichter gegeneinander horizontal quer zur Rotorachse verschiebbar sind, der Aufgabetrichter feststehend und der Rotor samt dem ihn lagernden Gehäuse unter dem Aufgabetrichter verschiebbar angeordnet sein, wobei der dem Rotor vorgelagerte, unter dem Aufgabetrichter bewegbare Gehäusebereich mit den nach oben zu schräg divergierenden Seitenwänden versehen ist. Dies hat den Vorteil, daß von einem ruhenden Holzstoß weggefräst wird, wodurch das abzufräsende Rohmaterial nur gegen Verschieben gehalten, nicht jedoch aktiv verschoben werden muß. Außerdem wird, wie schon angeführt, durch die schräg nach oben divergierenden Seitenwandungen des Troges ein Verspreizen zusätzlich noch dadurch verhindert, daß bei einseitiger Druckausübung auf ein längliches Holzstück, dessen Länge nur geringfügig größer als die Breite des Troges ist, dieses Holzstück schräg nach oben ausweichen kann, wodurch wieder ein Verspreizen verhindert wird.Finally, in a design in which the feed hopper has a pressure plate extending below the rotor axis, the rotor and the feed hopper being displaceable horizontally relative to one another transversely to the rotor axis, the feed hopper being stationary and the rotor together with the housing supporting it being displaceable under the feed hopper , wherein the housing area in front of the rotor, movable under the feed hopper, with the after is provided at the top to obliquely diverging side walls. This has the advantage that it is milled away from a steady pile of wood, as a result of which the raw material to be milled is only held against displacement, but does not have to be actively moved. In addition, as already mentioned, the diagonally upward diverging side walls of the trough prevent it from spreading further so that when one-sided pressure is exerted on an elongated piece of wood, the length of which is only slightly greater than the width of the trough, this piece of wood dodges obliquely upwards can, which prevents spreading again.

This counter knife is attached to a carrier 8. The counter knife 7 forms the continuation of a base plate 9 of a feed hopper 10. On the wall 11 opposite the rotor 3 there is an opening 12 provided, through which a pressure plate 13 can be moved. This pressure plate is perpendicular to the base plate 9 and is guided through the side walls 14. The pressure plate is driven by a hydraulic piston / cylinder unit 15, which is supported on a frame part 16 with its end facing away from the pressure plate 13. The pressure plate 13 is followed by a cover plate 17, which extends from the upper edge of the pressure plate 13 to the rear and thus covers the opening that would arise behind the pressure plate 13 upwards and thus prevents the material in the funnel 12 from falling into it.

Die unteren Bereiche der Seitenwandungen 14, welche in Fig. 2 mit 14' bezeichnet sind, verlaufen von der Bodenplatte 9 weg nach oben schräg nach außen geneigt, u.zw. vorliegend bis etwa in Höhe der Rotorantriebsachse. Oberhalb derselben verlaufen sie dann parallel und gehen in die Trichteraußenwandungen 14 über.The lower regions of the side walls 14, which are denoted by 14 'in FIG. 2, run inclined upwards outward from the base plate 9, and so on. in the present case up to approximately the height of the rotor drive axis. Above the same, they then run parallel and merge into the outer walls 14 of the funnel.

Bei Betrieb der Vorrichtung wird das zu zerkleinernde Gut in den Trichter 1 eingegeben und der Rotor 3 über den Motor 4 in Umdrehung versetzt. Das zu zerkleinernde Gut wird dann durch die Schneiden 2 und die Gegenschneide 7 zerkleinert und fällt unten in einen nicht näher dargestellten Auffangteil. Das Anpressen des zu zerkleinernden Gutes erfolgt über die Anpreßplatte 13, welche über die Kolben/Zylindereinheit 15 in Richtung zum Rotor 3 bewegt wird. Das vor der Anpreßplatte 13 befindliche Gut wird so an den Rotor in Anlage gehalten, daß ein zuverlässiges Zerkleinern ermöglicht ist, daß aber zuviel Material oberhalb des Rotors in den Trichter 10 zurückweichen kann. An der Rückseite der Anpreßplatte kann kein Gut hineinfallen, da der Raum durch den Abdeckschild 17 verschlossen ist.When the device is in operation, the material to be shredded is fed into the hopper 1 and the rotor 3 is rotated by the motor 4. The material to be shredded is then shredded by the cutting edges 2 and the shearbar 7 and falls into a collecting part (not shown in more detail below). The material to be comminuted is pressed on via the pressure plate 13, which is moved in the direction of the rotor 3 via the piston / cylinder unit 15. The material in front of the pressure plate 13 is held against the rotor in such a way that reliable comminution is possible, but that too much material can recede into the hopper 10 above the rotor. No goods can fall into the back of the pressure plate since the space is closed by the cover plate 17.

Beim Ausführungsbeispiel gemäß den Fig. 3 und 4 ist der Rahmen mit 21, die Schneidwerkzeuge mit 22, der Rotor mit 23, der Antriebsmotor mit 24, der Riementrieb mit 25, der Kettentrieb mit 26, die Gegenschneide mit 27, der diese tragende Teil mit 28, die Bodenplatte des Aufgabetrichters mit 29 und der Aufgabetrichter mit 30 bezeichnet. Die Bodenplatte 29 des Aufgabetrichters ist entlang einer Zylindermantelfläche gewölbt. Die Anpreßplatte 33 ist an einem Druckstempel 34 vorgesehen, welcher vorliegend durch ein geschweißtes Kastenprofil gebildet ist. Die Anpreßplatte 33 ist dabei durch eine Durchbrechung 31 der dem Rotor 23 gegenüberliegenden Wandung 32 des Trichters 30 hindurchbewegbar. Die eine Wandung 35 des Druckstempels ist dabei knapp oberhalb der Bodenplatte 29 bewegbar und weist eine Krümmung auf, die analog der Krümmung der Bodenplatte 29 verläuft. Die andere Begrenzungswandung des Kastenprofils, die Wandung 36, ist ebenfalls entlang einer Zylindermantelfläche gekrümmt, wobei die Krümmung der Zylindermantelflächen alle ein und denselben Mittelpunkt 37 aufweisen. An diesem Drehpunkt 37 sind Schwenkhebel 38 angeordnet, welche einen Querträger 39 tragen, der die freien Enden der Hebel 38 miteinander verbindet. An diesen Querträger 39 greift das Kastenprofil 34 an.In the embodiment according to FIGS. 3 and 4, the frame with 21, the cutting tools with 22, the rotor with 23, the drive motor with 24, the belt drive with 25, the chain drive with 26, the shear bar with 27, the part carrying this 28, the bottom plate of the hopper with 29 and the feed hopper designated 30. The base plate 29 of the feed hopper is curved along a cylindrical surface. The pressure plate 33 is on one Pressure stamp 34 is provided, which in the present case is formed by a welded box profile. The pressure plate 33 can be moved through an opening 31 in the wall 32 of the funnel 30 opposite the rotor 23. One wall 35 of the plunger can be moved just above the base plate 29 and has a curvature which is analogous to the curvature of the base plate 29. The other boundary wall of the box section, the wall 36, is also curved along a cylindrical surface, the curvature of the cylindrical surfaces all having one and the same center 37. At this pivot point 37 pivot levers 38 are arranged which carry a cross member 39 which connects the free ends of the levers 38 to one another. The box section 34 engages this cross member 39.

Die Schwenkhebel 38 sind über eine hydraulische Kolben/Zylindereinheit 40 verschwenkbar, welche mit ihrem einen Ende an den Schwenkhebeln bei 41 und am Rahmen bei 42 schwenkbar angelenkt sind.The swivel levers 38 can be swiveled via a hydraulic piston / cylinder unit 40, which are articulated at one end to the swivel levers at 41 and at the frame at 42.

Wie aus Fig. 5 ersichtlich, sind die unteren Bereiche 43 der parallel zu den Schwenkebenen der Hebeln 38 verlaufenden Seitenwandungen 44 schräg nach oben und außen geneigt, wogegen die Andrückplatte 33 rechteckig ausgebildet ist.As can be seen from FIG. 5, the lower regions 43 of the side walls 44 running parallel to the pivoting planes of the levers 38 are inclined upwards and outwards, whereas the pressure plate 33 is rectangular.

Bei Betrieb der Vorrichtung wird das zu zerkleinernde Gut nach Einschalten des Motors 24 und Indrehungversetzen des Rotors 23 eingegegeben, u.zw. bei der in Fig. 3 wiedergegebenen Stellung des Schwenkhebels. Danach wird die hydraulische Kolben/Zylindereinheit derart mit Druck beaufschlagt, daß ein Verkürzen der Kolben/Zylindereinheit bewirkt wird, wodurch die Schwenkhebeln 38 in Fig. 3 gesehen im Uhrzeigersinn verschwenkt werden, wodurch die Anpreßplatte 33 das zu zerkleinernde Gut an den Rotor 23 anpreßt, wodurch das Gut durch die Messer 22 und die Gegenschneidemesser 27 zerkleinert wird. Das zerkleinerte Gut fällt in eine Aufnahmeeinrichtung 45, aus welcher es mit einer Schnecke 46 ausgetragen wird.When the device is in operation, the material to be shredded is entered after the motor 24 has been switched on and the rotor 23 has been rotated, etc. in the position shown in Fig. 3 of the pivot lever. The hydraulic piston / cylinder unit is then pressurized in such a way that the piston / cylinder unit is shortened, as a result of which the pivot levers 38 are pivoted clockwise as seen in FIG. 3, as a result of which the pressure plate 33 presses the material to be comminuted onto the rotor 23. whereby the material is comminuted by the knives 22 and the counter-cutting knives 27. The comminuted material falls into a receiving device 45, from which it is discharged with a screw 46.

Bei der Ausführungsvariante gemäß den Fig. 6 - 9 sind auf einem Fundament 51 vertikale Steher 52 fest angeordnet, welche einen Aufgabetrichter 53 tragen. Unterhalb des Aufgabetrichters 53 ist ein verfahrbarer Gehäuseteil 54 vorgesehen, welcher einen mit Zerkleinerungswerkzeugen 56 versehenen Rotor 55 trägt. Dem Rotor vorgeschaltet ist ein Aufnahmetrog für das zu zerkleinernde Gut, dessen Seitenwände mit 57 und dessen Boden mit 57' bezeichnet sind. Die Seitenwände des Aufgabetrichters 53 liegen direkt oberhalb der Oberkanten der Seitenwände 57. Die Seitenwände 57 des Aufnahmetroges divergieren nach oben zu vom Boden 57' ausgehend als teilweise Gegenschneiden für die äußersten Zerkleinerungswerkzeuge 56. Dem Rotor nachgeschaltet ist ein Auflageschild 58 vorgesehen, welches horizontal verläuft und in der oberen Schneidebene des Rotors angeordnet ist. Dieses Auflageschild ist mit dem verfahrbaren Gehäuseteil 54 fest verbunden und mit diesem verfahrbar. Unterhalb des Rotors 55 ist ein Auswurf 59 vorgesehen, welcher die zerkleinerten Teilchen einer nicht näher dargestellten Austrageeinrichtung zuführt. Diese Austrageeinrichtung kann jeglicher Art sein, wobei die Förderrichtung in Bewegungsrichtung des Gehäuseteiles 54 angeordnet sein wird.In the embodiment variant according to FIGS. 6-9, vertical uprights 52 are fixedly arranged on a foundation 51 and carry a feed hopper 53. A movable housing part 54 is provided below the feed hopper 53, which carries a rotor 55 provided with comminution tools 56. The Upstream of the rotor is a receiving trough for the material to be shredded, the side walls of which are designated 57 and the bottom of which is designated 57 '. The side walls of the feed hopper 53 lie directly above the upper edges of the side walls 57. The side walls 57 of the receiving trough diverge upwards from the bottom 57 'as partial counter-cutting for the outermost comminution tools 56. A support plate 58 is provided downstream of the rotor, which runs horizontally and is arranged in the upper cutting plane of the rotor. This support plate is firmly connected to the movable housing part 54 and movable with it. An ejector 59 is provided below the rotor 55, which feeds the comminuted particles to a discharge device (not shown). This discharge device can be of any type, the conveying direction being arranged in the direction of movement of the housing part 54.

Die in Vorschubrichtung des Gehäuses 54 hintere Stirnwand des Aufgabetrichters 60 ist bis zum Boden 57' des Aufnahmetroges für zu zerkleinerndes Gut, welches in den Fig. 4a - c mit 61 angedeutet ist, heruntergezogen und wirkt als Andrückplatte 60'.The rear wall of the feed hopper 60 in the feed direction of the housing 54 is pulled down to the bottom 57 'of the receiving trough for material to be shredded, which is indicated by 61 in FIGS. 4a-c, and acts as a pressure plate 60'.

Die Funktionsweise der erfindungsgemäßen Vorrichtung wird nachstehend anhand der Fig. 9a - c geschildert. In Fig. 9a ist der Beginn der Zerkleinerungstätigkeit und der Vorschubbewegung des Gehäuseteiles 54 angedeutet. Mittels des Rotors wird durch die Zerkleinerungswerkzeuge 56 das aufgegebene Restholz in kleine Stücke zerkleinert und durch den Auswurf 59 in die nicht dargestellte Abtransporteinrichtung eingebracht. Der Gehäuseteil 54 wird in Richtung des Pfeils P gemäß Fig. 9b mit einer Geschwindigkeit vorgeschoben, welche der Zerkleinerungsleistung des Rotors mit den Zerkleinerungswerkzeugen 56 entspricht. Das oberhalb der Beweegungsbahn des Rotors 55 verbleibende zu zerkleinernde Gut 61 bleibt auf dem Auflageschild 58 liegen und gleitet auf demselben entsprechend der Vorschubbewegung des Gehäuseteiles 54. Eine derartige Mittelstellung ist in Fig. 9b wiedergegeben. Der Vorschub des Gehäuseteiles 54 in Richtung des Pfeiles P erfolgt so lange, bis die in Fig. 9c wiedergegebene Endstellung erreicht ist, bei welcher die Stirnwand des Aufgabetrichters 53 unmittelbar vor dem Rotor 55 zu liegen kommt. Das im Aufgabetrichter 53 verbleibende zu zerkleinernde Gut 61 liegt dann zur Gänze auf dem Auflageschild 58 auf.The mode of operation of the device according to the invention is described below with reference to FIGS. 9a-c. In Fig. 9a the beginning of the crushing and the feed movement of the housing part 54 is indicated. By means of the rotor, the shredded tools 56 shred the discarded wood into small pieces and bring it into the removal device (not shown) through the ejection 59. The housing part 54 is advanced in the direction of the arrow P according to FIG. 9b at a speed which corresponds to the shredding power of the rotor with the shredding tools 56. The material 61 to be comminuted which remains above the movement path of the rotor 55 remains on the support plate 58 and slides thereon in accordance with the feed movement of the housing part 54. Such a central position is shown in FIG. 9b. The housing part 54 is advanced in the direction of the arrow P until the end position shown in FIG. 9c is reached, in which the end wall of the feed hopper 53 comes to lie directly in front of the rotor 55. The material 61 to be shredded remaining in the feed hopper 53 then lies entirely on the support plate 58.

Sollte ein längeres Holzstück quer zur Vorschubrichtung des Gehäuseteiles 54 zu liegen kommen, was unter Umständen zu einem Verspreizen zwischen den beiden Seitenwänden 57 führen könnte, dann wird durch die Vorwärtsbewegung und den durch das übrige Holz auf dieses querliegende Holzstück ausgeübten Druck das Holzstück an der Schräge der Wandungen 57 nach oben gleiten, wodurch das Verspreizen verhindert ist.Should a longer piece of wood come to lie transversely to the direction of advance of the housing part 54, which could possibly lead to a spreading between the two side walls 57, then the piece of wood becomes inclined due to the forward movement and the pressure exerted on this transverse piece of wood by the remaining wood of the walls 57 slide upwards, thereby preventing the spreading.
