Description

Mischtrommel rnittkegelstumpfförmigem Oberteil, einer diesem sich anschließenden Ringwand und einem mit sanfter Krümmung in die Ringwand und in eine Bodenlagerhülse übergehenden, mit Mischrippen versehenen Boden. Sehr bewährt haben sich die bekannten Mischtrommeln, bei denen ein kegelstumpfförmiger Oberteil mit einer diesem sich anschließenden Ringwand und einem Boden derart vereinigt sind, .daß unter Vermeidung scharfer Ecken und Winkel der Boden mit sanfter Krümmung in die Ringwand und in eine Bodenlagerhülse übergeht.Mixing drum with a frustoconical upper part, one of which is itself subsequent ring wall and one with a gentle curve in the ring wall and one Bottom bearing sleeve overhanging the bottom with mixed ribs. Have proven very effective the well-known mixing drums, in which a frustoconical upper part with a ring wall adjoining this and a floor are combined in such a way that .that, while avoiding sharp corners and angles, the floor is gently curved in the ring wall and merges into a floor bearing sleeve.

Bei Versuchen zur Steigerung der Wirkung dieser Trommeln durch Anbringung der bekannten Mischrippen haben sich bei sonst durchaus befriedigender Arbeit Miß,erfolge dort gezeigt, wo fortlaufend größere Mengen vollkommen gleichmäßig gemischten Betons für hochwertige Arbeiten verlangt werden. Es hat sich nun gezeigt, daß diese Mißefolge auf die Bildung von »toten Winkeln« am Xippenfuß zurückzuführen sind, die sich mit dem noch ungenügend gemischten Gut alsbald vollsetzen, so daß auch langdauerndes Mischen kein völlig einheitliches Mischgut ergeben bann.When trying to increase the effectiveness of these drums by attaching them The well-known mixed ribs have failed with otherwise entirely satisfactory work shown where continuously larger amounts of perfectly evenly mixed concrete are required for high quality work. It has now been shown that this failure can be traced back to the formation of "dead spots" at the Xippenfoot, which are related to Immediately complete the still insufficiently mixed goods, so that long-lasting Mixing does not result in a completely uniform mixture.

Gemäß der Erfindung werden diese Mißefolge dadurch beseitigt, daß diese bekannten Rippen in Richtung ihres Querschnittes mit sanfter Krümmung in den Trommelboden übergeführt werden.According to the invention, these inconveniences are eliminated in that these known ribs in the direction of their cross-section with a gentle curvature in the Drum base are transferred.

Die Zeichnung veranschaulicht ein Ausführungsbeispiel des Erfindungsgegenstandes in einem mittleren Längsschnitt durch den Trommelmantel.The drawing illustrates an embodiment of the subject matter of the invention in a central longitudinal section through the drum shell.

Die Trommel a hat einen keg@e@stumpfförmigen Oberteil b, einen. sich daran anschließenden Ringteil c und Boden d. Letzterer ist gekrümmt, so daß er in die Ringwand c und in die mittlere Lagerhülsee übergeht. Der Boden, d hat aufragende Rippen oder Vorsprünge f, die gekrümmt sind und in den Boden nächst den Rippen mit sanfter Krümmung in Richtung des Rippenquerschnitts übergehen.The drum a has a keg @ e @ truncated upper part b, a. themselves adjoining ring part c and bottom d. The latter is curved so that it is in the ring wall c and merges into the middle bearing sleeve. The floor d has soaring Ribs or protrusions f that are curved and in the ground next to the ribs with smooth curvature in the direction of the rib cross-section.

Eine solche Trommel,hat keine Ecken und Winkel für das. Festsetzen des Gutes und auch keine ebenen Flächen am Boden.Such a drum has no nooks and crannies for that of the goods and also no flat surfaces on the ground.

An der Innenwand der Trommel sind durch Träger g Paare von Mischflügeln h diagonal zum Lagere angebracht. Ein Ende jedes der äußeren Flügel hat einen gebogenen oder abgesetzten Teil y.On the inner wall of the drum are pairs of mixing blades through supports g h attached diagonally to the bearing. One end of each of the outer wings has a curved one or offset part y.

Beim Mischen wirken die Flügel h mit den Rippen f zusammen und lassen das Gut in einer Anzahl verschiedener Richtungen wandern, so daß ein inniges und gründliches Mischen gewährleistet wird.When mixing, the wings h cooperate with the ribs f and let the goods migrate in a number of different directions, so that an intimate and thorough mixing is ensured.
