Bei einem aus der Praxis bekannten Ringtrogzwangsmischer dieser Art besteht der Drehantrieb der Wirblerwelle aus einem Hydromotor, der über eine separate Hydraulikpumpe mit Servoverstellung angetrieben wird und je nach Mischrezept stufenlos zwischen 0 bis 200 U/min steuerbar ist. Dieser hydraulische Antrieb der Wirblerwelle ist nicht nur wegen des benötigten Hydromotors mit zugehöriger Hydropumpe aufwendig, sondern er wird zusätzlich noch durch die erforderliche Drehdurchführung verteuert. Aufgabe der Erfindung ist es daher, einen Ringtrogzwangsmischer der eingangs angegebenen Art zu schaffen, der mit einem kostengünstigeren Antrieb für den Wirbler versehen ist. In a ring trough positive mixer known from practice this The rotary drive of the vortex shaft consists of a hydraulic motor, via a separate hydraulic pump with servo adjustment is driven and, depending on the mixing recipe, continuously between 0 is controllable up to 200 rpm.

Erfindungsgemäß wird diese Aufgabe bei einem Ringtrogzwangsmischer der gattungsgemäßen Art dadurch gelöst, daß mit dem nabenförmigen Teil ein flaches, einen radialen Arm einschließendes Gehäuse verbindbar ist, in dessen Mittelteil eine zentrale, mit der Rührwerkswelle fluchtende Welle gelagert ist, auf die drehfest ein zentrales Zahnrad aufgekeilt ist und dessen oben aus dem Gehäuse herausgeführtes Wellenende durch eine Drehmomentenstütze gegenüber dem Trog abgestützt ist, und daß in dem armförmigen Teil des Gehäuses mindestens ein Ritzel gelagert ist, das den Antrieb von dem zentralen Zahnrad auf den Wirbler überträgt und mit einem auf die Wirblerwelle aufgekeilten Zahnrad kämmt. Der erfindungsgemäße Antrieb zeichnet sich durch große Robustheit und Wirtschaftlichkeit aus, da er keinen zusätzlichen Antriebsmotor benötigt, sondern über die Getriebemittel von dem Rührwerksantrieb abgeleitet ist. Auch bereits im Betrieb befindliche Ringtrogzwangsmischer ohne Wirbler können in einfacher Weise mit dem erfindungsgemäßen Wirbler nachgerüstet werden.According to the invention, this object is achieved with a ring trough positive mixer of the generic type solved in that with the hub-shaped Part of a flat one enclosing a radial arm Housing is connectable, in the middle part of a central, with the agitator shaft aligned shaft is mounted on the rotatable a central gear is keyed up and its top out the shaft end led out through a torque arm is supported against the trough, and that in the arm-shaped Part of the housing at least one pinion is mounted, that transfers the drive from the central gear to the swirler and with a gear wheel wedged onto the vortex shaft combs.

Aus DE-C-31 14 477 ist ein Ringtrogzwangsmischer bekannt, bei dem der Antrieb der Wirbler über Stirnradstufen von dem Mischwerksantrieb abgeleitet wird. Dieser bekannte Ringtrogzwangsmischer weist jedoch insofern eine aufwendige Konstruktion auf, als in dem Innenraum des Ringtrogs ein mit einem Getriebegehäuse versehenes Getriebe eingesetzt und in dem Zwischenraum zwischen dem Getriebegehäuse und der Troginnenwand ein mit einer Innenverzahnung versehener Zahnkranz trogfest angeordnet ist, mit dem zur Ableitung des Wirblerantriebs ein Zahnrad kämmt, das auf eine ein Ritzel des Stirnradgetriebes lagernde Welle aufgesetzt ist, die die Bodenplatte des Rotorgehäuses des Ringtrogzwangsmischers durchsetzt.From DE-C-31 14 477 a ring trough positive mixer is known, at which is the drive of the whirlers via spur gear stages from the mixer drive is derived.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß die Wirbler an einem Ring befestigt sind, der auf dem Ende der Wirblerwelle frei drehbar gelagert und gegenüber der Wirblerwelle durch Abscherstifte drehfest gehalten ist. Sollten die Wirbler durch in dem Mischgut befindliche Steine oder andere Widerstände blockiert werden, wird eine Beschädigung des Ringtrogzwangsmischers dadurch vermieden, daß die Abscherstifte abgeschert werden und die Wirbler trotz der weiteren Drehung der Wirblerwelle stehenbleiben.In a further embodiment of the invention it is provided that the Vortexes are attached to a ring on the end of the vortex shaft freely rotatable and opposite to the vortex shaft is held against rotation by shear pins.
