Abstract
Description
Die Erfindung betrifft einen Horizontalmischer für Mörtel, bei dem seitlich an einem Materialbehälter ein Stutzen sitzt, der mit einem Mischrohr zusammengesteckt ist, bei dem in den Stutzen eine Antriebswelle ragt, die mit einer in dem Mischrohr befindlichen Mischwendel verbunden ist, wobei das Mischrohr von dem Stutzen und der Mischwendel abziehbar ist, bei dem in einer elektrischen Zuleitung zu einem Antriebsmotor der Antriebswelle eine Steckkupplung sitzt, die ein festsitzendes Steckerstück und ein bewegbares Kupplungsstück umfaßt, und bei dem eine Sicherheitseinrichtung einen in der Zuleitung befindlichen elektrischen Teil und einen mechanischen Teil umfaßt, der einerseits an dem Mischrohr und andererseits an dem Stutzenbereich des Materialbehälters angeordnet ist.The invention relates to a horizontal mixer for mortar which sits on the side of a material container, the with a mixing tube is put together, in which in the nozzle a drive shaft protrudes with one located in the mixing tube Mixing coil is connected, the mixing tube from the Socket and the mixing spiral is removable, in an electrical Lead to a drive motor of the drive shaft Plug-in coupling sits, which is a stuck plug and a movable Coupling comprises, and in which a safety device an electrical part located in the supply line and comprises a mechanical part, on the one hand on the mixing tube and on the other hand arranged on the nozzle area of the material container is.
Bei einem durch die Praxis bekannten Horizontalmischer dieser Art sitzt die Steckkupplung an einer gegenüber dem Stutzenbereich um 90° versetzten Wandung des Materialbehälters.In a horizontal mixer of this type known from practice the plug-in coupling is seated at one opposite the nozzle area 90 ° offset wall of the material container.
Der zwischen dem festsitzenden Steckerstück und dem Antriebsmotor verlaufende Abschnitt der elektrischen Zuleitung ist über einen elektrischen Schalter geführt, der im Stutzenbereich angebracht ist und von einem Druckstück betätigt wird, das am Mischrohr angebracht ist. Wenn das Mischrohr von der Wendel abgezogen wird, gibt das Druckstück den Schalter frei, der sodann abschaltet, so daß die Mischwendel sich nicht weiter dreht, sondern zum Stillstand kommt. Durch die Sicherheitseinrichtung ist also verhindert, daß bei abgezogenem Mischrohr die rotierende Mischwendel zugänglich ist. Jedoch sind bei dem bekannten Horizontalmischer der Schalter und dessen Zusammenwirken mit dem Druckstück störanfällig, so daß die Sicherheitseinrichtung häufig ausfällt.The one between the stuck connector and the drive motor extending section of the electrical lead is over a led electrical switch, which is attached in the nozzle area and is actuated by a pressure piece which is attached to the mixing tube is. When the mixing tube is pulled off the helix, the pressure piece releases the switch, which then switches off, so that the mixing spiral no longer turns, but to a standstill is coming. The safety device thus prevents When the mixing tube is removed, the rotating mixing helix is accessible is. However, in the known horizontal mixer, the switch and its interaction with the pressure piece prone to failure, so that the safety device often fails.
Eine Aufgabe der Erfindung ist es daher, einen Horizontalmischer der eingangs genannten Art zu schaffen, bei dem die Sicherheitseinrichtung robuster bzw. weniger störanfällig gestaltet ist. Der erfindungsgemäße Horizontalmischer ist, diese Aufgabe lösend, dadurch gekennzeichnet, daß die Steckkupplung den elektrischen Teil der Sicherheitseinrichtung bildet und im Stutzenbereich angebracht ist und daß das bewegbare Kupplungsstück und ein am Mischrohr angebrachtes Hakenmittel den mechanischen Teil der Sicherheitseinrichtung bildet, wobei das Hakenmittel das Kupplungsstück hintergreift.An object of the invention is therefore a horizontal mixer to create the type mentioned, in which the safety device is more robust or less prone to failure. The invention Horizontal mixer is thereby solving this problem characterized in that the plug-in coupling the electrical part of the Safety device forms and is attached in the nozzle area and that the movable coupling piece and one attached to the mixing tube Hook means the mechanical part of the safety device forms, the hook means engaging behind the coupling piece.
Bei dem erfindungsgemäßen Horizontalmischer ist die Steckkupplung dann, wenn das Mischrohr abgezogen ist, zwangsläufig gelöst, so daß der Antriebsmotor durch Auseinanderziehen der Steckkupplung stillgesetzt ist. Die Sicherheitseinrichtung des erfindungsgemäßen Horizontalmischers vermeidet einen zusätzlichen elektrischen Schalter und ist robuster bzw. weniger störanfällig. Wenn das Mischrohr wieder an den Stutzen montiert ist, läßt sich das Kupplungsstück wieder auf das Steckerstück stecken. Das Mischrohr wird in Richtung seiner Mittelachse aufgeschoben und abgenommen und der Hintergriff des Hakenmittels ist rechtwinkelig zu der Mittelachse und so, daß das Hakenmittel gegen das Kupplungsstück drückt, wenn man das Mischrohr bei zusammengefügter Steckkupplung abnehmen will.In the horizontal mixer according to the invention, the plug-in coupling is then when the mixing tube is pulled off, inevitably loosened, so that the drive motor by pulling the plug coupling apart is stopped. The safety device of the invention Horizontal mixer avoids an additional electrical Switch and is more robust or less prone to failure. If that Mixing tube is mounted on the nozzle again, the coupling piece can be put it back on the connector. The mixing tube is pushed on and removed in the direction of its central axis and the rear grip of the hook means is perpendicular to the central axis and so that the hook means against the coupling piece presses when the mixing tube with the plug-in coupling assembled want to lose weight.
Besonders zweckmäßig und vorteilhaft ist es, wenn die Steckkupplung mit ihrer Mittelachse rechtwinkelig zur Mittelachse des Mischrohrs angeordnet ist und das Hakenmittel einer Mantelfläche des Kupplungsstückes zugeordnet ist. Bei dieser Gestaltung muß das Kupplungsstück abgezogen werden, bevor das Mischrohr abgezogen werden kann.It is particularly expedient and advantageous if the plug-in coupling with its central axis perpendicular to the central axis of the mixing tube is arranged and the hook means of a lateral surface of the Coupling piece is assigned. With this design, the The coupling piece must be removed before the mixing tube is removed can be.
Besonders zweckmäßig und vorteilhaft ist es auch, wenn das Hakenmittel über ca. 180° offen ist. Das Hakenmittel umschließt das Kupplungsstück nicht rundum und behindert somit das Anfügen des Kupplungsstückes an das Steckerstück weniger.It is also particularly expedient and advantageous if the hook means is open over approx. 180 °. The hook means encloses this Coupling piece not all around and thus hinders the attachment of the coupling piece to the connector piece less.
Besonders zweckmäßig und vorteilhaft ist es noch, wenn das Hakenmittel einem Bereich des Kupplungsstückes zugeordnet ist, der in sich ein Teil des Steckerstückes aufnimmt. Kräfte, die das Hakenmittel auf das Kupplungsstück ausübt, werden von der Steckkupplung verbessert aufgenommen.It is particularly expedient and advantageous if the hook means is assigned to an area of the coupling piece which takes up part of the connector. Forces that the hook means exerted on the coupling piece by the plug-in coupling improved recorded.
Besonders zweckmäßig und vorteilhaft ist es ebenso, wenn das Hakenmittel und die Steckkupplung am Umfang des Stutzens um 90° gegeneinander versetzt angeordnet sind. Bei dieser Anordnung zueinander läßt sich die Sicherheitseinrichtung vereinfacht bedienen bzw. betätigen.It is also particularly expedient and advantageous if the hook means and the plug-in coupling on the circumference of the nozzle by 90 ° are mutually offset. With this arrangement to each other the safety device can be operated in a simplified manner or press.
Eine besonders zweckmäßige und vorteilhafte Ausführungsform der Erfindung liegt vor, wenn der Stutzen und das Mischrohr im Steckbereich ein Innenteil und ein Außenteil bilden, von denen eines einen einseitig offenen axialen Riegelspalt bildet und das andere einen radialen Riegelzapfen trägt, der bei zusammengestecktem Zustand durch den Riegelspalt ragt. Wenn der Stutzen und das Mischrohr zusammengesteckt sind, aber noch nicht gegeneinander festgelegt sind, dann könnte die rotierende Mischwendel das Mischrohr relativ zum Stutzen drehend bewegen, was wegen des Hakenmittels zu einer Beschädigung der Steckkupplung führen könnte. Eine solche Drehbewegung ist durch die Verriegelung verhindert.A particularly useful and advantageous embodiment of the Invention exists when the nozzle and the mixing tube in the plug area form an inner part and an outer part, one of which forms an axial locking gap open on one side and the other a radial locking pin carries when plugged together protrudes through the bolt gap. If the nozzle and the mixing tube are put together, but not yet fixed against each other then the rotating mixing spiral could be the mixing tube move relative to the nozzle, which is because of the hook means could damage the plug-in coupling. Such Rotation is prevented by the lock.
