Der Erfindung liegt die Aufgabe zugrunde, eine Fräsvorrichtung der eingangs genannten Art anzugeben, die möglichst vielseitig einsetzbar ist.The invention has for its object to provide a milling device of the type mentioned, which is as versatile as possible.

Diese Aufgabe wird erfindungsgemäß durch eine gattungsgemäße Fräsvorrichtung mit den Merkmalen des kennzeichnenden Teils des Anspruchs 1 gelöst. Eine derartige Fräsvorrichtung ist dadurch gekennzeichnet, dass am Fräsrad mindestens ein zweites Fräselement zum Abtragen von Bodenmaterial bei einer entgegengerichteten zweiten Drehrichtung angeordnet ist, dass mindestens eines der Fräselemente zwischen einer ersten Position zum Abtragen von Bodenmaterial und einer rückgezogenen zweiten Position verstellbar gelagert ist, und dass eine Stelleinrichtung zum Verstellen des Fräselementes zwischen der ersten und der zweiten Position vorgesehen ist.This object is achieved by a generic Milling device with the features of the characteristic part of claim 1 solved. Such a milling device is characterized that at least one second on the milling wheel Milling element for removing soil material in the opposite direction second direction of rotation is arranged that at least one of the milling elements between a first position for Removal of soil and a retracted second position is adjustable, and that an adjusting device to adjust the milling element between the first and the second position is provided.

Ein Grundgedanke der Erfindung liegt darin, an dem um eine Drehachse drehbaren Fräsrad sowohl ein erstes Fräselement als auch ein zweites Fräselement anzubringen, wobei das erste Fräselement bei einer Drehung des Fräsrades in einer ersten Drehrichtung, das zweite Fräselement hingegen bei einer Drehung des Fräsrades in einer entgegengesetzten zweiten Drehrichtung am Fräsrad anstehendes Bodenmaterial abträgt. Mindestens eines der Fräselemente ist dabei durch eine Stelleinrichtung zwischen einer ersten Position, in welcher es Bodenmaterial an der Wand des Schlitzes abtragen kann, und einer rückgezogenen zweiten Position, in der vorzugsweise keine Bodenbearbeitung erfolgt, verstellbar gelagert. Bevorzugt sind die Fräselemente in einer Umfangsrichtung des Fräsrades hintereinander angeordnet. Bevorzugt ist ferner das verstellbar gelagerte Fräselement so angeordnet, dass zumindest ein Teil hiervon in der ersten Position radial weiter von der Drehachse des Fräsrades beabstandet ist, als in der zweiten Position. Insbesondere sind die Fräselemente derart angeordnet, dass das verstellbar gelagerte Fräselement in der ersten Position gegenüber dem jeweils anderen Fräselement in einer radialen Richtung des Fräsrades zumindest teilweise hervorsteht, wohingegen in der zweiten Position das jeweils andere Fräselement zumindest teilweise gegenüber dem verstellbaren Fräselement radial hervorsteht. Hierdurch wird erreicht, dass in Abhängigkeit von der Position des verstellbaren Fräselementes entweder das verstellbare Fräselement oder das andere Fräselement den Boden an der Wand des Schlitzes bearbeitet. Somit wird ein besonders vielseitig einsetzbares Fräsrad geschaffen.A basic idea of the invention is based on the one Rotating axis rotatable milling wheel both a first milling element and also to attach a second milling element, the first milling element when the milling wheel rotates in a first Direction of rotation, the second milling element, however, when turning of the cutting wheel in an opposite second direction of rotation removes soil material from the milling wheel. At least one of the milling elements is through an actuating device between a first position in which there is soil material can erode on the wall of the slot, and a retracted second position, in which preferably no tillage done, adjustable storage. Those are preferred Milling elements in a circumferential direction of the milling wheel one behind the other arranged. The adjustable bearing is also preferred Milling element arranged so that at least part of it in the first position radially further from the axis of rotation of the Milling wheel is spaced apart than in the second position. In particular the milling elements are arranged in such a way that they are adjustable stored milling element in the first position opposite the other milling element in a radial direction of the cutting wheel protrudes at least partially, whereas in the second position at least the other milling element partially radial compared to the adjustable milling element protrudes. This ensures that depending on the position of the adjustable milling element either the adjustable Milling element or the other milling element to the ground machined the wall of the slot. This makes it special versatile milling wheel created.

Das Verstellen des verstellbar gelagerten Fräselementes erfolgt dabei vorzugsweise in Abhängigkeit von der Drehrichtung des Fräsrades. Ist dabei das erste Fräselement verstellbar, so erfolgt das Verstellen vorzugsweise so, dass sich das erste Fräselement bei einer Drehung des Fräsrades in einer ersten Drehrichtung in der ersten Position zum Abtragen von Bodenmaterial befindet, bei einer Drehung in der entgegengerichteten zweiten Drehrichtung hingegen in der rückgezogenen zweiten Position. Ist das verstellbar gelagerte Fräselement das zweite Fräselement, so wird es bevorzugt bei einer Drehung in der zweiten Drehrichtung in die erste Position gebracht. Ein solches drehrichtungsabhängiges Verstellen ermöglicht, dass bei einer reversierenden Drehung des Fräsrades immer nur das für die jeweilige Drehrichtung vorgesehene Fräselement mit der Wand des Schlitzes in Kontakt steht und dort Bodenmaterial abträgt. Das jeweils andere Fräselement befindet sich hingegen in der rückgezogenen Position, wo es von einer Einwirkung des allgemein sehr harten abzutragenden Bodenmaterials geschützt ist. Hierdurch wird ein Betrieb des Fräsrades mit einer guten Fräsleistung in beiden Drehrichtungen ermöglicht und gleichzeitig ein übermäßiger Verschleiß der Fräselemente vermieden.The adjustable milling element is adjusted preferably depending on the direction of rotation of the milling wheel. If the first milling element is adjustable, so the adjustment is preferably carried out so that the first Milling element when the milling wheel rotates in a first Direction of rotation in the first position to remove soil material is located, when rotating in the opposite direction second direction of rotation, however, in the retracted second position.

Hierdurch wird gewährleistet, dass sich beim Fräsen jeweils nur eines der Fräselemente in der ersten Position zum Abtragen von Bodenmaterial befindet, wohingegen das jeweils andere in die geschützte zweite Position zurückgezogen ist.A preferred embodiment of the milling device according to the invention is characterized in that the first milling element and the second milling element are adjustable. hereby this results in a particularly flexible milling device.
