Description

Die Erfindung betrifft einen Hackrotor für eine Zerkleinerungsmaschine, wobei der Hackrotor Werkzeugaufnahmen umfasst und wobei in den Werkzeugaufnahmen ein überlastgesichertes Werkzeug aufnehmbar ist.The invention relates to a chopping rotor for a crushing machine, wherein the chopping rotor comprises tool holders and wherein in the tool holders an overload-protected tool can be accommodated.

Bekannte Zerkleinerungsmaschinen weisen Hackrotoren auf, die einen geringen Vorgriff, das heißt einen geringen Abstand zwischen einer Hackmesserkante bzw. einer Messerklinge und dem Rotorkörper aufweisen. Die damit hergestellten Hackschnitzel sind entsprechend kleiner dimensioniert und weisen im Verbrennungsvorgang einen nachteilig hohen Aschenanteil auf. Bei bekannten Hackrotoren kann der Vorgriff zum Herstellen größerer Hackschnitzel auch nur schlecht vergrößert werden, da hierzu die Festigkeit des Hackrotors nicht ausreichend ist und/oder ein Verstellen mit erheblichem Zeitaufwand verbunden ist.Known crushing machines have pecking rotors which have a slight advance, that is to say a small distance between a chopping knife edge or a knife blade and the rotor body. The chips produced in this way are dimensioned correspondingly smaller and have a disadvantageously high ash content in the combustion process. In known pecking rotors the Vorgriff for producing larger chips can also be increased only bad, since this is the strength of the chopping rotor is not sufficient and / or adjustment is associated with considerable expenditure of time.

Vor diesem Hintergrund ist es Aufgabe der Erfindung einen verbesserten Hackrotor bereitzustellen, mittels dem größere Hackschnitzel oder sowohl größere als auch kleinere Hackschnitzel einfacher bzw. mit geringem Verstellaufwand erzeugt werden können.Against this background, it is an object of the invention to provide an improved hacking rotor by means of which larger wood chips or both larger and smaller chips can be produced more easily or with little adjustment effort.

Diese Aufgabe wird erfindungsgemäß durch einen Hackrotor mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausbildungen sind Gegenstand der Unteransprüche. Demnach ist ein Hackrotor vorgesehen, bei dem eine Messerklinge des Werkzeugs in einer insbesondere tangentialen Richtung des Hackrotors zur Verstellung des Vorgriffs des Werkzeugs verstellbar ist. Mit der tangentialen Richtung des Hackrotors kann hierbei die Richtung gemeint sein, in der sich die Messerklinge bei Drehung des Hackrotors bewegt. Denkbar sind auch Ausführungen, bei denen die Messerklinge in eine alternative oder zusätzliche Richtung verstellbar mit dem restlichen Gefüge des Werkzeugs koppelbar ist. Dabei kann die Messerklinge z.B. in einer radialen Richtung von einer zentralen Drehachse des Hackrotors weg bewegt werden.This object is achieved by a hack rotor with the features of claim 1. Advantageous embodiments are the subject of the dependent claims. Accordingly, a chopping rotor is provided in which a knife blade of the tool in a particular tangential direction of the chopping rotor for adjusting the Vorgriffs of the tool is adjustable. With the tangential direction of the chopping rotor in this case may be meant the direction in which the knife blade moves upon rotation of the chopping rotor. Designs are also conceivable in which the knife blade can be coupled in an alternative or additional direction adjustably with the rest of the structure of the tool. The knife blade may e.g. be moved in a radial direction away from a central axis of rotation of the chopping rotor.

Durch die Verstellbarkeit der Messerklinge kann eine besonders einfache Veränderung des Vorgriffs bewirkt werden. Dies insbesondere, als Messerklingen bei gattungsgemäßen Hackrotoren bzw. Werkzeugen ohnehin auswechselbar ausgeführt sein können. Dadurch ist es einfacher möglich, bestehende Werkzeuge so weiterzubilden, dass daran montierte Messerklingen nicht mehr lediglich auswechselbar sondern auch verstellbar bzw. in wenigstens zwei verschiedenen Positionen an dem Werkzeug montierbar sind.Due to the adjustability of the knife blade a particularly simple change of the Vorgriffs can be effected. This particular, as knife blades can be performed interchangeable anyway in generic pecking rotors or tools anyway. This makes it easier to further develop existing tools so that knife blades mounted thereon are not only replaceable but also adjustable or can be mounted on the tool in at least two different positions.

In einer bevorzugten Ausführung kann vorgesehen sein, dass die Messerklinge zwischen einem unteren und einem oberen Werkzeughalter mittels wenigstens einer Befestigungsschraube feststellbar ist. Die Befestigungsschraube kann dabei radial nach außen bezogen auf den Hackrotor gerichtet sein, so dass sie zum Wechseln der Messerklinge einfach zugänglich bzw. drehbar ist. Die Ausrichtung der Befestigungsschraube kann auch von einer radialen Richtung abweichen, so lange der Schraubenkopf der Befestigungsschraube oder eine mit der Befestigungsschraube wechselwirkende Mutter von einer radial äußeren Richtung des Hackrotors gut für Bedien- bzw. Wartungspersonal zugänglich sind.In a preferred embodiment it can be provided that the knife blade between a lower and an upper tool holder by means of at least one fastening screw is lockable. The fastening screw can be directed radially outward relative to the hack rotor, so that it is easily accessible or rotatable for changing the knife blade. The orientation of the fastening screw may also deviate from a radial direction, as long as the screw head of the fastening screw or nut interacting with the fastening screw are well accessible to operating or maintenance personnel from a radially outer direction of the chopping rotor.

In einer besonders bevorzugten Ausführung kann vorgesehen sein, dass die Messerklinge mittels zweier insbesondere in Drehrichtung des Hackrotors bzw. Werkzeugs nebeneinander angeordneter Befestigungsschrauben feststellbar ist. Die Drehrichtung des Werkzeugs kann hierbei die Richtung bezeichnen, in die sich das am Hackrotor vorgesehene Werkzeug bei dessen Rotationsdrehung bewegt. Mittels der beiden Befestigungsschrauben kann die Messerklinge besonders einfach verdrehfest mit den Werkzeughaltern und/oder der weiteren Struktur des Werkzeugs gekoppelt werden.In a particularly preferred embodiment, it can be provided that the knife blade can be fixed by means of two fastening screws arranged side by side, in particular in the direction of rotation of the chopping rotor or tool. The direction of rotation of the tool can in this case designate the direction in which the tool provided on the chipping rotor moves during its rotation rotation. By means of the two fastening screws, the knife blade can be particularly easily coupled rotationally with the tool holders and / or the other structure of the tool.

In einer weiteren bevorzugten Ausführung ist denkbar, dass die Messerklinge mittels wenigstens einer Verstellschraube relativ zu den Werkzeughaltern verstellbar ist. Die wenigstens eine Verstellschraube kann hierbei in Bewegungsrichtung der Messerklinge orientiert sein und in einem der Schneide der Messerklinge gegenüberliegenden Bereich der Messerklinge mit dieser wechselwirken. Mit der Bewegungsrichtung der Messerklinge kann vorliegend die gleiche Richtung gemeint sein, in die die Messerklinge zum Verstellen des Vorgriffs verstellbar ist.In a further preferred embodiment, it is conceivable that the knife blade is adjustable relative to the tool holders by means of at least one adjustment screw. The at least one adjusting screw can in this case be oriented in the direction of movement of the knife blade and interact with it in an area of the knife blade opposite the cutting blade of the knife blade. In the present case, the direction of movement of the knife blade may be the same direction in which the knife blade is adjustable for adjusting the advance.

In einer weiteren bevorzugten Ausführung ist denkbar, dass die Messerklinge wenigstens ein Langloch und/oder wenigstens eine Ausnehmung zum Aufnehmen der Befestigungsschraube umfasst. Das Langloch oder die insbesondere längliche Ausnehmung kann dabei in Bewegungsrichtung der Messerklinge orientiert sein. Hierdurch ist es vorteilhaft möglich, eine abgenutzte und/oder zu verstellende Messerklinge parallel zum Verlauf des Langlochs oder der länglichen Ausnehmung und/oder in Bewegungsrichtung der Messerklinge relativ zu den Werkzeughaltern und/oder relativ zu der Befestigungsschraube zu bewegen und dann weiter als zuvor aus den Werkzeughaltern herausragend an diesen festzustellen. Damit kann eine verbrauchte bzw. abgenutzte Messerklinge zu ihrer Erneuerung bzw. zu ihrem Schärfen und zu ihrer weiteren Benutzung positioniert werden und/oder es kann die erfindungsgemäß durchführbare Verstellung des Vorgriffs des Werkzeugs vorgenommen werden.In a further preferred embodiment, it is conceivable that the knife blade comprises at least one slot and / or at least one recess for receiving the fastening screw. The slot or the particular elongated recess can be oriented in the direction of movement of the knife blade. This makes it advantageously possible to move a worn and / or knife blade to be adjusted parallel to the course of the slot or the elongated recess and / or in the direction of movement of the knife blade relative to the tool holders and / or relative to the mounting screw and then further than before from the Tool holders outstanding to determine this. Thus, a worn or worn knife blade can be positioned for its renewal or for sharpening and for its further use and / or it can be made according to the invention feasible adjustment of the Vorgriffs of the tool.

In einer weiteren bevorzugten Ausführung ist denkbar, dass der untere Werkzeughalter über wenigstens einen Werkzeugträger mit dem Hackrotor koppelbar ist. Besonders bevorzugt kann ferner vorgesehen sein, dass an der Messerklinge und/oder an dem Werkzeughalter eine Scherschraube zur Störstoffsicherung vorgesehen ist. Die Scherschraube kann bei Überschreiten einer bestimmten, an ihr auftretenden Belastung die mittels ihr hergestellte Kopplung zwischen beispielsweise dem Werkzeugträger und weiteren Strukturen des Hackrotors oder zwischen der Messerklinge und weiteren Strukturen des Werkzeugs lösen.In a further preferred embodiment, it is conceivable that the lower tool holder can be coupled to the pecking rotor via at least one tool carrier. Particularly preferably, it can further be provided that a shear screw for securing foreign matter is provided on the knife blade and / or on the tool holder. The shear screw can solve when it exceeds a certain load occurring on her by means of her produced coupling between, for example, the tool carrier and other structures of the hacking rotor or between the knife blade and other structures of the tool.

In einer weiteren bevorzugten Ausführung ist denkbar, dass der untere Werkzeughalter und/oder der Werkzeugträger vom Inneren des Hackrotors mit diesem montiert/gekoppelt sind. Hierzu können beispielsweise radial nach innen orientierte Feststellmittel wie Schrauben und/oder Muttern vom Werkzeugträger und/oder vom Werkzeughalter in sonstige Strukturen des Hackrotors hineinragen und eine Verbindung zwischen dem Hackrotor und dem Werkzeug herstellen.In a further preferred embodiment, it is conceivable that the lower tool holder and / or the tool carrier are mounted / coupled to the interior of the chopping rotor with this. For this purpose, for example, radially inwardly oriented locking means such as screws and / or nuts protrude from the tool carrier and / or the tool holder in other structures of the chopping rotor and make a connection between the chopping rotor and the tool.

Die Erfindung ist ferner auf eine Zerkleinerungsmaschine mit einem Hackrotor nach einem der Ansprüche 1 bis 8 und auf ein Werkzeug für einen Hackrotor nach einem der Ansprüche 1 bis 8 gerichtet. Die Zerkleinerungsmaschine bzw. das Werkzeug können hierbei beliebige Merkmale umfassen, die vorliegend im Zusammenhang mit dem Hackrotor beschrieben sind, sofern die Merkmale für den Fachmann offensichtlich sinnvoll mit den genannten Vorrichtungen kombinierbar sind. Auf eine Wiederholung diesbezüglicher Ausführungen wird daher verzichtet.The invention is further directed to a shredding machine with a chopping rotor according to one of claims 1 to 8 and to a tool for a chopping rotor according to one of claims 1 to 8. In this case, the comminution machine or the tool can comprise any features which are described in the present case in connection with the chipping rotor, provided that the features obviously make sense for the person skilled in the art to be combined with the said devices. A repetition in this regard is therefore omitted.
