Description
Die Erfindung betrifft einen Häcksler der im Oberbegriff des Anspruchs 1 angegebenen Gattung.The invention relates to a shredder specified in the preamble of
Beispielsweise aus der
Für Häckselgut und Schnitzelgut sind unterschiedliche Zuführwinkel zu der Messerscheibe vorteilhaft. Zu häckselndes Gut soll möglichst senkrecht auf die Messerscheibe fallen, während für Äste oder dgl. ein schräger Zuführwinkel zu der Messerscheibe vorteilhaft ist. Die bei bekannten Häckslern vorgesehenen zwei Zuführungen für Häckselgut und für zu zerschnitzelndes Gut sind vergleichsweise aufwendig. Bei der Zufuhr von Häckselgut kann das Zuführrohr für Äste den Bediener behindern, da es die Zugänglichkeit des Zuführrohrs für Häckselgut einschränkt.For shredded material and Schnitzelgut different feed angle to the knife disc are advantageous. Good to be chopped good should fall as perpendicular to the cutter blade, while for branches or the like. An oblique feed angle to the cutter disk is advantageous. The provided in known shredders two feeds for shredded and for to be shredded Good are relatively expensive. When feeding shredded material, the branch supply pipe may obstruct the operator, as it limits the accessibility of the shredded feed pipe.
Aus der
Der Erfindung liegt die Aufgabe zugrunde, einen Häcksler der gattungsgemäßen Art zu schaffen, der einfach aufgebaut ist und der auf einfache Weise zu bedienen ist.The invention has for its object to provide a shredder of the generic type, which is simple and easy to use.
Diese Aufgabe wird durch einen Häcksler mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a shredder with the features of
Es ist vorgesehen, dass ein einziges Zuführrohr in mehrere Betriebspositionen für unterschiedliche Betriebsarten des Häckslers gestellt werden kann. Dadurch ist es möglich, über ein einziges Zuführrohr sowohl Häckselgut als auch zu zerschnitzelndes Gut wie Äste oder dgl. zuzuführen, da dieses Zuführrohr in die unterschiedlichen vorgesehenen Betriebspositionen verstellt werden kann. Dadurch können mit einem einzigen Zuführrohr, also einer einzigen Zuführgosse, unterschiedliche Materialien in dem jeweils für diese Materialien vorteilhaften Zuführwinkel zugeführt werden. Eine Behinderung des Bedieners durch ein weiteres Zuführrohr ist nicht gegeben.It is envisaged that a single feed tube can be placed in several operating positions for different operating modes of the chopper. As a result, it is possible to supply both shredded material and material to be shredded, such as branches or the like, via a single feed pipe, since this supply pipe can be adjusted to the different operating positions provided. As a result, different materials can be supplied to the feeding angle which is advantageous in each case for these materials with a single feed tube, that is, a single feed nozzle. Disruption of the operator by another feed pipe is not given.
Vorteilhaft ist die erste Betriebsart der Häckselbetrieb, wobei die Längsmittelachse des Zuführrohrs in der ersten Betriebsposition zur Drehachse der Zerkleinerungseinheit insbesondere etwa parallel liegt. Als etwa parallel wird ein Winkel zwischen Längsmittelachse und Drehachse weniger als 5° angesehen. Vorteilhaft beträgt der Winkel zwischen Längsmittelachse und Drehachse etwa 0°. Bei dieser Ausrichtung des Zuführrohrs fällt das Häckselgut annährend senkrecht auf die Messerscheibe. Dadurch wird ein gutes Häckselergebnis erreicht. Vorteilhaft ist die zweite Betriebsart der Schnitzelbetrieb, wobei die Längsmittelachse des Zuführrohrs in der zweiten Betriebsposition gegenüber der Drehachse der Messerscheibe um einen Winkel von 20° bis 70° geneigt ist. Vorzugsweise schließt die Längsmittelachse des Zuführrohrs mit der Drehachse der Zerkleinerungseinheit, insbesondere einer Messerscheibe einen Winkel von 30° bis 60° ein. Dadurch wird ein gutes Schnitzelergebnis erreicht.The first mode of operation of the chopping operation is advantageous, wherein the longitudinal center axis of the feed tube in the first operating position relative to the axis of rotation of the comminution unit is in particular approximately parallel. As approximately parallel, an angle between the longitudinal central axis and the axis of rotation is considered to be less than 5 °. Advantageously, the angle between the longitudinal central axis and the axis of rotation is about 0 °. In this orientation of the feed tube, the shreds fall approximately perpendicular to the cutter disk. This achieves a good chopping result. Advantageously, the second mode of operation is the Schnitzelbetrieb, wherein the longitudinal central axis of the feed tube is inclined in the second operating position relative to the axis of rotation of the cutter disc by an angle of 20 ° to 70 °. Preferably, the longitudinal center axis of the feed tube encloses an angle of 30 ° to 60 ° with the axis of rotation of the comminution unit, in particular a cutter disc. This achieves a good schnitzel result.
Kommen die für das Zerschnitzeln von Ästen vorgesehenen Messer der Zerkleinerungseinheit im Häckselbetrieb mit zu häckselndem Gut und mit eventuell beigemengter Erde oder dgl. in Kontakt, können die Messer schnell stumpf werden. Um dies zu vermeiden, ist vorgesehen, dass die Drehrichtung der Zerkleinerungseinheit zwischen einer ersten Drehrichtung und einer zweiten Drehrichtung umschaltbar ist, wobei jede Drehrichtung einer Betriebsart des Häckslers zugeordnet ist. Die Messer für Häckselbetrieb bzw. die Messer zum Zerschnitzeln sind dabei auf der Zerkleinerungseinheit, insbesondere einer Messerscheibe so angeordnet, dass sie jeweils nur in einer Drehrichtung in Eingriff mit zu zerkleinerndem Gut kommen. Dadurch ist ein vorzeitiges Abstumpfen der Messer für den Schnitzelbetrieb vermieden.If the knives of the shredding unit provided for the shredding of branches come into contact with the material to be chopped and with possibly added soil or the like in the shredding operation, the knives can quickly become dull. To avoid this, it is provided that the direction of rotation of the comminution unit can be switched between a first direction of rotation and a second direction of rotation, wherein each direction of rotation is assigned to an operating mode of the chopper. The knives for shredding operation or the knives for shredding are arranged on the shredding unit, in particular a knife disc so that they come in each case only in one direction of rotation in engagement with good to be shredded. As a result, premature dulling of the blades for the Schnitzelbetrieb is avoided.
Bei bekannten Häckslern kann die Drehrichtung der Zerkleinerungseinheit, insbesondere der Messerscheibe vom Bediener umgeschaltet werden. Um die Bedienung des Häckslers zu vereinfachen, ist vorgesehen, dass die Drehrichtung der Zerkleinerungseinheit in Abhängigkeit der Betriebsposition des Zuführrohrs gesteuert ist. Je nach Betriebsposition des Zuführrohrs wird die Drehrichtung für die zugeordnete Betriebsart des Häckslers eingestellt. Dadurch sind Fehlbedienungen vermieden. Um zwischen den Betriebsarten umzuschalten, muss der Bediener lediglich die Stellung des Zuführrohrs ändern. Die Drehrichtung der Zerkleinerungseinheit wird automatisch entsprechend umgeschaltet, so dass ein separates Umschalten der Drehrichtung durch den Bediener entfällt.In known choppers, the direction of rotation of the crushing unit, in particular the cutter disk can be switched by the operator. To simplify the operation of the chopper, it is provided that the direction of rotation of the crushing unit is controlled in dependence on the operating position of the feed tube. Depending on the operating position of the feed tube the direction of rotation is set for the assigned operating mode of the chopper. As a result, operating errors are avoided. To switch between modes, the operator only needs to change the position of the feed tube. The direction of rotation of the shredding unit is automatically switched accordingly, so that a separate switching of the direction of rotation by the operator is eliminated.
Vorteilhaft besitzt der Häcksler eine Betriebsartenanzeige, die die Betriebsart des Häckslers in Abhängigkeit der Betriebsposition des Zuführrohrs anzeigt. Anhand der angezeigten Betriebsart kann der Bediener die Drehrichtung des Antriebsmotors einstellen. Aufgrund der Betriebsartenanzeige weiß der Bediener, welche Art von Schnittgut in dieser Stellung des Zuführrohrs zuzuführen ist. Dabei kann vorgesehen sein, dass in Abhängigkeit der Stellung des Zuführrohrs sowohl die Drehrichtung des Antriebsmotors gesteuert als auch die Betriebsart des Häckslers angezeigt wird.Advantageously, the shredder has a mode indicator indicating the operating mode of the chopper depending on the operating position of the feed tube. Based on the displayed operating mode, the operator can set the direction of rotation of the drive motor. Due to the operating mode display, the operator knows which type of material to be cut is to be supplied in this position of the feed pipe. It can be provided that, depending on the position of the feed tube both the direction of rotation of the drive motor controlled and the operating mode of the chopper is displayed.
Zum Umschalten der Drehrichtung des Antriebsmotors und/oder zur Steuerung der Betriebsartenanzeige ist vorgesehen; dass der Häcksler mindestens einen Schalter aufweist, der in einer Betriebsposition des Zuführrohrs betätigt und in der anderen Betriebsposition des Zuführrohrs nicht betätigt ist. Dabei kann auch für jede Betriebsposition des Zuführrohrs ein separater Schalter vorgesehen sein.For switching the direction of rotation of the drive motor and / or for controlling the mode indicator is provided; in that the chopper has at least one switch which is actuated in an operating position of the feed pipe and is not actuated in the other operating position of the feed pipe. In this case, a separate switch can also be provided for each operating position of the feed tube.
Um die Einstellung der optimalen Betriebspositionen für den Bediener zu erleichtern, ist vorgesehen, dass der Häcksler mindestens einen Anschlag zur Festlegung einer Betriebsposition des Zuführrohrs aufweist.In order to facilitate the setting of the optimum operating positions for the operator, it is provided that the chopper Has at least one stop for determining an operating position of the feed tube.
Vorteilhaft ist das Zuführrohr um eine etwa senkrecht zur Drehachse der Zerkleinerungseinheit liegende Schwenkachse zwischen den Betriebspositionen verschwenkbar. Es kann jedoch auch vorgesehen sein, dass das Zuführrohr zwischen den Betriebspositionen um eine Drehachse drehbar ist, die gegenüber der Drehachse der Zerkleinerungseinheit um einen Winkel geneigt ist. Insbesondere ist das Zuführrohr an einem Rohrstutzen am Gehäuse des Häckslers drehbar gelagert, wobei das Zuführrohr an dem Rohrstutzen in einer Verbindungsebene gelagert ist, die gegenüber der Drehachse der Zerkleinerungseinheit geneigt ist.Advantageously, the feed tube is pivotable about an approximately perpendicular to the axis of rotation of the crushing unit pivot axis between the operating positions. However, it can also be provided that the feed tube between the operating positions is rotatable about an axis of rotation which is inclined relative to the axis of rotation of the comminution unit by an angle. In particular, the feed tube is rotatably mounted on a pipe socket on the housing of the chopper, wherein the feed tube is mounted on the pipe socket in a connection plane which is inclined relative to the axis of rotation of the shredding unit.
