Description

Die vorliegende Erfindung betrifft einen Bechermischer zum Mischen fester Aggregate und Abgeben des Gemisches. Insbesondere betrifft die Erfindung einen Bechermischer zum Mischen von festen Aggregaten, beispielsweise von Betonaggregaten, von jenem Typ, der ein Gefäß und eine innere Mischschnecke umfasst, welche sich um eine Achse dreht, die parallel zur Längsachse des Gefäßes verläuft.The present invention relates to a cup mixer for mixing solid aggregates and dispensing the Mixture. In particular, the invention relates to a cup mixer for mixing solid aggregates, for example concrete aggregates, of the type that a vessel and a inner mixing screw, which rotates about an axis that parallel to the longitudinal axis of the vessel.

Weiterhin ist der Bechermischer dieser Erfindung von jenem Typ, welcher eine Mehrzahl von Schaufeln vorsieht, die am Umfangsteil der Mischschnecke angebracht sind, um sich radial bis in die Nähe der Kante des Gefäßes zu erstrecken, wobei die Schaufeln in einer Windungsrichtung, die jener der Mischschnecke entgegengesetzt ist, ausgerichtet sind, um die doppelte Wirkung beim Reinigen und Abkratzen der Gefäßwände zu erzielen und das Material in die entgegen gesetzte Richtung von jener, welche beim Betrieb des Bechermischers durch die Mischschnecke vermittelt wird, zu treiben.Furthermore, the cup mixer is this Invention of the type which provides a plurality of blades which are attached to the peripheral part of the mixing screw to radially up close to extend the edge of the vessel the blades in a winding direction, that of the mixing screw is opposite, are aligned to double the effect to achieve when cleaning and scraping the vessel walls and the material in the opposite direction from that in operation of the cup mixer is conveyed by the mixing screw.

Das US-Patent Nr. 4, 224, 996 offenbart eine Vorrichtung der oben besprochenen Art und schlägt vor, dass die Schaufeln am Umfangsteil der Mischschnecke angeschweißt oder auf andere Weise starr, fest oder entfernbar daran befestigt werden können. Gemäß diesem Dokument wird das Befestigen durch Einspannen der Innenkante der Schaufel in einer Ausnehmung, welche in der Mischschnecke vorgesehen wird, erreicht. Diese Lösung schwächt zunächst einmal die Mischschnecke an jenen Punkten, an denen sich die Ausnehmungen befinden. Überdies macht sie es schwierig, ein System zum lösbaren Befestigen der Schaufel am Umfangsteil der Mischschnecke bereitzustellen, da diese beiden Glieder an einem Punkt, an dem sie verhältnismäßig hohen Verdrehbelastungen ausgesetzt werden, in einem im Wesentlichen rechten Winkel in Bezug zueinander angeordnet sind. Letztens neigt aus denselben Gründen auch die Schaufel dazu, sich rasch zu verformen. Ein Austausch der Schaufel kann sich auf Grund der Weise, in der sie an die Mischschnecke gekoppelt ist, schwierig oder unmöglich gestalten.U.S. Patent No. 4,224,996 discloses a device of the type discussed above and proposes that the blades are welded to the peripheral part of the mixing screw or otherwise rigidly, firmly or removably attached thereto can. According to this The document is fastened by clamping the inner edge of the Bucket in a recess, which is provided in the mixing screw is achieved. This solution weakens first once the mixing screw at those points where the recesses are are located. moreover makes it difficult to have a system for releasably securing the bucket to provide at the peripheral part of the mixing screw, since these two Limbs at a point where they have relatively high torsional loads be exposed at a substantially right angle with respect are arranged to each other. Lately also tends to for the same reasons the shovel to deform quickly. An exchange of the shovel can change due to the way in which it is coupled to the mixing screw is difficult or impossible shape.

Das Italienische Patent Nr. 1,210,783, welches als den ähnlichsten Stand der Technik darstellend betrachtet wird, offenbart einen Bechermischer gemäß dem Oberbegriff des unabhängigen Anspruchs 1, wobei jede Schaufel schwenkbar an einem Träger befestigt ist, der an die Mischschnecke geschweißt ist, um sich aus einer eingefahrenen Position in der Nähe der Achse der Mischschnecke in eine ausgefahrene Position in der Nähe des Gefäßes zu drehen.Italian Patent No. 1,210,783, which as the most similar Considered prior art, discloses a cup mixer according to the preamble of the independent Claim 1, wherein each blade is pivotally attached to a carrier is, which is welded to the mixing screw, in order to get out of a retracted Position nearby the axis of the mixing screw into an extended position in the Near the To rotate the vessel.

In der Praxis hat sich gezeigt, dass sich Betonmaterial oder andere Materialien, die gemischt werden, im Lauf der Zeit, wenn nicht ständig sorgfältiges Reinigen durchgeführt wird, an den Zwischenräumen zwischen der Schaufel und dem Träger verfestigen und dadurch die Schaufel in einer Position blockieren. Dadurch wird jeglicher Nutzen, den ein schwenkbares Befestigen der Schaufel haben könnte, zunichte gemacht. Darüber hinaus kann, sollte es zu einer derartigen Blockade kommen, wenn die Schaufel eingefahren ist, der Boden des Gefäßes nicht mehr ausgekratzt und leer gemacht werden. Zudem ist der Austausch der Schaufeln ein überaus schwieriger und komplexer Vorgang.Practice has shown that concrete material or other materials that are mixed over time, if not constantly careful Cleaning done will, at the gaps between the bucket and the carrier solidify and thereby block the bucket in one position. This will provide any benefit that a pivotable attachment of the Shovel could have destroyed. About that in addition, there should be such a blockage if the bucket is retracted, the bottom of the vessel is no longer scraped out and be made empty. Replacing the blades is also an extremely difficult task and complex process.

Es wurde auch erkannt, dass es nicht nötig ist, dass sich die Schaufeln drehen, um die Wände des Gefäßes zu berühren, um eine effiziente und vollständige Reinigung zu erzielen. Da sich die Schaufeln im Lauf der Zeit abnutzen, sollte stattdessen eine Vorkehrung getroffen werden, um zu ermöglichen, die Schaufeln bei Nichtvorliegen der Bindesysteme, welche beide Glieder schwächen, rasch auszuwechseln.It was also recognized that it was not is necessary that the blades rotate to touch the walls of the vessel for efficient and full To achieve cleaning. As the blades wear out over time, provision should instead be made to enable the Buckets in the absence of the binding systems, which are both links weaknesses, replace quickly.

Diese und weitere Aufgaben, welche in der Folge noch deutlicher erkennbar werden, werden gemäß der vorliegenden Erfindung durch das Vorsehen eines Bechermischers zum Mischen fester Aggregate und Abgeben des Gemisches gemäß Anspruch 1 realisiert.These and other tasks, which subsequently become even more clearly recognizable, according to the present Invention by the provision of a cup mixer for mixing solid Aggregates and dispensing the mixture according to claim 1 realized.
