Technisches GebietTechnical field
Die Erfindung betrifft eine Schlegelanordnung für Rotorschredder mit einem um eine Achse drehbar gelagerten Grundkörper und einem Schneidkörper, der an einem Vorsprang des Grundkörpers lösbar befestigt ist. Solche Schlegel werden als Schlagwerkzeug bei Rotorschreddern zum Beispiel für Kunststoff, Holz oder dergleichen verwendet.The invention relates to a flail arrangement for rotor shredders with a base body rotatably mounted about an axis and a cutting body which is detachably attached to a projection of the base body. Such flails are used as impact tools in rotor shredders, for example for plastic, wood or the like.

Aus der DE 35 45 708 C2 ist eine Schlegelanordnung bekannt, bei der ein als Zahn ausgebildeter Schneidkörper mit einem Schaft in einer Ausnehmung auswechselbar befestigt ist. Die Befestigung erfolgt mittels einer Schraube, die durch eine Bohrung im Grundkörper und durch den Schaft des Schneidkörpers ragt. Der Schaft ist am Ende mit einer vorstehenden Ecke versehen, die hinter einen Vorsprang in der Ausnehmung greift. Weiterhin ist der Schaft mit einem Profil versehen, das in ein komplementäres Profil in der Ausnehmung ragt. Dadurch wird der Zahn auch bei starken Kräften in seiner Lage gehalten. Üblicherweise wird dabei die Schlegelspitze so abgenutzt, daß sich eine Kante entlang der Drehbewegung des Schlegels bildet. Durch die komplexe Formgebung der beschriebenen Schlegelanordnung ist sie aufwendig herzustellen.From DE 35 45 708 C2 a flail arrangement is known in which a cutting body designed as a tooth is interchangeably fastened with a shaft in a recess. It is fastened by means of a screw which protrudes through a hole in the base body and through the shaft of the cutting body. The shaft is provided at the end with a protruding corner which engages behind a projection in the recess. Furthermore, the shaft is provided with a profile which projects into a complementary profile in the recess. As a result, the tooth is held in position even with strong forces. Usually the flail tip is worn so that an edge forms along the rotational movement of the flail. Due to the complex shape of the flail arrangement described, it is complex to manufacture.

Jeder Schlegel besteht aus einem Grundkörper, der an einem Ende schwenkbar an dem Rotorkörper gelagert ist und aus einem Schneidkörper, der an der in Umlaufrichtung vorderen Fläche des Schlegels angebracht ist. Diese Schneidkörper sind austauschbar an dem jeweiligen Schlegel befestigt, da sie im Betrieb der Vorrichtung schnellem Verschleiß unterworfen sind und somit ersetzt werden können, ohne daß dafür ein Austausch des gesamten Schlegels erforderlich wäre.Annual plants known. The device contains a rotor body, near the circumference of which flails are arranged pivotably. Each mallet consists of one Base body which is pivotally mounted on the rotor body at one end and consists of a cutting body which is attached to the front surface of the flail in the circumferential direction. These cutting bodies are exchangeably attached to the respective flail, since they are subject to rapid wear during operation of the device and can therefore be replaced without having to replace the entire flail.
Bei beiden Anordnungen wird vergleichsweise viel Material, nämlich der gesamte Schneidkorper, unbrauchbar, wenn die Schlegelspitze ausgetauscht wird.In both arrangements, a comparatively large amount of material, namely the entire cutting body, becomes unusable when the flail tip is replaced.

The profile on the base body corresponds to a profile on the cutting body, for example a recess. As a result, the cutting body has less volume with a correspondingly lower material consumption.
In einer bevorzugen Ausgestaltung der Erfindung hat das Profil die Form eines hervorstehenden Pyramidenstumpfes, dessen Grundfläche in der Ebene der vorderen Fläche des Vorsprungs liegt.

With this configuration, the cutting body can be used several times.

Beschreibung eines AusführungsbeispielsDescription of an embodiment
In Fig. 1 ist mit 10 ein Rotorschlegel bezeichnet. Der Rotorschlegel 10 umfasst einen Grundköφer 12 und einen mit einer Schraube 14 aufgeschraubten Schneidköφer 16, der die Schlegelspitze bildet. Der Grundköφer 12 besteht aus einem Hohlzylinder 18, der um eine Achse 20 drehbar gelagert ist. An dem Hohlzylinder ist ein Vorsprung 22 angeformt. Der Vorsprung 22 ist im wesentlichen stufenförmig ausgebildet, wobei die "Stufe" eine Fläche 24 aufweist, auf welcher der Schneidköφer 16 aufliegt. Die Fläche 24 zeigt in Richtung der Rotationsbewegung, die durch einen Pfeil 26 in Fig.l dargestellt ist. Sie bildet somit die Vorderfläche des Grundköφers 12. Der Schneidköφer 16 liegt formschlüssig auf dem Grandköφer 12 auf. Durch die stufenförmige Anordnung wird der Schneidköφer 16 von zwei Seiten von dem Grundköφer 12 umgeben und bildet mit ihm eine Einheit in welche kein Schneidgut eindringen kann.In Fig. 1, 10 is a rotor flail. The rotor flail 10 comprises a basic body 12 and a cutting body 16 screwed on with a screw 14, which forms the flail tip. The Grundköφer 12 consists of a hollow cylinder 18 which is rotatably mounted about an axis 20. A projection 22 is formed on the hollow cylinder. The projection 22 is essentially stepped, the "step" having a surface 24 on which the cutting body 16 rests. The surface 24 points in the direction of the rotational movement, which is represented by an arrow 26 in Fig.l. It thus forms the front surface of the basic body 12. The cutting body 16 lies positively on the grand body 12. Due to the step-like arrangement, the cutting body 16 is surrounded on two sides by the basic body 12 and forms with it a unit into which no material to be cut can penetrate.
Der Schneidköφer 16 weist über seine gesamte Breite einen gleichmäßigen trapezförmigen Querschnitt auf. Die kleinere Parallelfläche 26 des Trapezes bildet die rückwärtige Seite des Schneidköφers 16, welche auf der Vorderfläche 24 des Grundköφers 12 aufliegt. Der vordere Teil 28 des Schneidköφers 16 ist gehärtet. Dadurch wird die Abnutzung der Schneidflächen verzögert. Der Schneidköφer kann auch aus zwei Teilen, einem gehärteten Vorderteil und einem nicht gehärteten Rückteil, die miteinander verbunden werden, bestehen.The cutting body 16 has a uniform trapezoidal cross section over its entire width. The smaller parallel surface 26 of the trapezoid forms the rear side of the cutting body 16, which rests on the front surface 24 of the basic body 12. The front part 28 of the cutting body 16 is hardened. This delays the wear of the cutting surfaces. The cutting body can also consist of two parts, a hardened front part and an unhardened back part, which are connected to one another.
Der vordere Teil 28 des Schneidköφers umfasst zwei Schneidkanten 30 und 32, die auf gegenüberliegenden Seiten des Schneidköφers parallel zueinander angeordnet sind. In anderen Ausfuhrungsbeispielen sind vier Schneidkanten auf jeder Seite des Schneidköφers in einem Winkel von etwa 90 Grad zueinander angeordnet. DieThe front part 28 of the cutting body comprises two cutting edges 30 and 32 which are arranged parallel to one another on opposite sides of the cutting body. In other exemplary embodiments, four cutting edges are arranged on each side of the cutting body at an angle of approximately 90 degrees to one another. The
Schneidkanten 30 und 32 stehen etwas nach vorne vor. Entsprechend verläuft die Oberfläche 34 bzw. 36 unter einem Winkel etwas schräg auf die Kanten zu. Dadurch wird eine optimale Schneidwirkung erreicht. Zur Erreichung einer guten Stabilität verläuft der mittlere Teil 38 der Vorderfläche zwischen den Schneidkanten 30 und 32' gerade, d.h. parallel zur rückwärtigen Fläche 26 des Schneidköφers. Der spitze Winkel des Trapezes im Querschnitt ist an seinem Ende 40 und 42 etwas abgestumpft. Dies ist in Fig.3 nochmals dargestellt.Cutting edges 30 and 32 protrude slightly forward. Accordingly, the surfaces 34 and 36 run at a slight angle towards the edges. This ensures an optimal cutting effect. In order to achieve good stability, the middle part 38 of the front surface between the cutting edges 30 and 32 'runs straight, ie parallel to the rear surface 26 of the cutting body. The acute angle of the trapezoid in cross section is somewhat blunted at its ends 40 and 42. This is shown again in Figure 3.
Die rückwärtige Oberfläche des Grandköφers 12, sowie seine achsferne Oberfläche 44 sind nicht genau eben. Dadurch sind die Widerstände gegenüber dem Schneidgut etwas geringer. Die achsferne Oberfläche 44 verläuft derart, daß sie sich kantenfrei an die Seitenfläche 46 des Schneidköφers 16 anschließt. In Fig.2 ist der Grandköφer 12 ohne Schneidköφer dargestellt. Man erkennt an der Vorderfläche 24 des Grundköφers 12 ein angeformtes Profil 50 in Form eines Pyramidenstumpfes. In dem Pyramidenstumpf 50 ist eine Bohrung 52 für die Schraube 14 vorgesehen. Die Seiten 54 verlaufen unter einem Winkel von 90 Grad zueinander und zwei Seiten weisen Kanten auf, die parallel zu den Schneidkanten 30, 32 verlaufenThe rear surface of the Grand body 12, as well as its surface 44 remote from the axis, are not exactly flat. As a result, the resistance to the material to be cut is somewhat lower. The surface 44 remote from the axis runs in such a way that it adjoins the side surface 46 of the cutting body 16 without edges. In Fig.2 the Grandköφer 12 is shown without Schneidköφer. A molded profile 50 in the form of a truncated pyramid can be seen on the front surface 24 of the basic body 12. A bore 52 for the screw 14 is provided in the truncated pyramid 50. The sides 54 run at an angle of 90 degrees to one another and two sides have edges which run parallel to the cutting edges 30, 32
(Fig.3).(Fig.3).
Der Schneidköφer 16 weist auf seiner Rückseite eine Ausnehmung auf, die komplementär zu dem Profil 50 ist. Durch diese Anordnung kann der Schneidköφer 16 nur in vier verschiedenen Lagen mit dem Grandköφer verschraubt oder sonstwie darauf befestigt werden. Eine Justierung ist nicht erforderlich. Im vorliegenden Fall wird der Schneidköφer 16 jeweils so aufgesetzt, daß eine der beiden Schneidkanten 30, 32 parallel zur Rotationsachse 20 des Schlegels verläuft. Ist die Schneidkante durch Abnutzung stumpf geworden, wird die Schraube 14 gelöst, der Schneidköφer um 180 Grad gedreht und mit der Schraube 14 wieder befestigt. Dann sitzt eine "frische"The Schneidköφer 16 has on its back a recess that is complementary to the profile 50. With this arrangement, the cutting body 16 can only be screwed to the grand body in four different positions or otherwise attached to it. Adjustment is not necessary. In the present case, the cutting body 16 is placed in such a way that one of the two cutting edges 30, 32 runs parallel to the axis of rotation 20 of the flail. If the cutting edge has become blunt due to wear, the screw 14 is loosened, the cutting body is rotated by 180 degrees and fastened again with the screw 14. Then there is a "fresh"
Schneidkante an der Stelle der vorherigen. Werden Schneidkanten auf jeder Seite des Schneidköφers 16 vorgesehen, so kann der Schneidköφer vierfach statt zweifach genutzt werden. Wenn noch mehr Schneidkanten vorgesehen werden sollen, so muß die Anzahl der Seiten des Pyramidenstumpfes 50 erhöht werden.Cutting edge in the place of the previous one. If cutting edges are provided on each side of the cutting body 16, the cutting body can be used four times instead of twice. If more cutting edges are to be provided, the number of sides of the truncated pyramid 50 must be increased.
Auf der rückwärtigen Seite des Grandköφers 12 ist eine Ausnehmung 60 vorgesehen. Die Schraube 14 ragt durch eine Bohrung 62 im Schneidköφer 16 und die Bohrung 52 im Grundköφer. In der Ausnehmung 60 ist eine passende Mutter 64 für die Schraube 14 angeordnet. Dadurch brauchen die Bohrungen 52 und 62 nicht mit einem Gewinde versehen werden, was natürlich ebenfalls möglich ist. Durch die geschützte Lage vonA recess 60 is provided on the rear side of the Grand body 12. The screw 14 protrudes through a bore 62 in the cutting body 16 and the bore 52 in the basic body. A suitable nut 64 for the screw 14 is arranged in the recess 60. As a result, the bores 52 and 62 do not need to be provided with a thread, which of course is also possible. Due to the protected location of
Schraubenkopf und Mutter werden diese durch das Schneidgut nicht oder nur geringfügig beeinträchtigt. The screw head and nut are not affected or only slightly affected by the material to be cut.
