Description

Betonspritzmaschine mit einem sich nach unten verjüngenden Behälter für das Spritzmaterial und einem Taschenrad Die Erfindung betrifft eine Betonspritzmaschine mit einem sich nach unten verjüngenden Behälter für das Spritzmaterial und einem Taschenrad, das in einem unten am Behälter angeordneten Gehäuse in horizontaler Ebene umläuft, wobei das von den Taschen mitgenommene Spritzgut durch Druckluft in einen Materialaustnttsstutzen geblasen wird. Beim Durchgang des Spritzgutes durch die oben und unten offenen Taschen des Taschenrades hindurch sind sowohl die Wandung als auch der Boden des Taschenradgehäuses einem starken Verschleiß durch Abrieb ausgesetzt, wodurch das aufwendige Taschenradgehäuse in kurzer Zeit unbrauchbar wird. Concrete spraying machine with a container that tapers towards the bottom for the spray material and a pocket wheel The invention relates to a concrete spraying machine with a downwardly tapering container for the spray material and a Pocket wheel in a horizontal housing arranged at the bottom of the container Level, with the spray material carried along by the pockets by compressed air is blown into a material removal nozzle. When the spray material passes through the pockets of the pocket wheel, which are open at the top and bottom, are both the wall as well as the bottom of the pocket wheel housing is subject to heavy wear due to abrasion exposed, making the complex pocket wheel housing unusable in a short time will.

Nach der Erfindung ist daher vorgesehen, daß zwischen dem Taschenrad und dem Boden sowie der Wandung des Taschenradgehäuses ein auswechselbarer Verschleißring vorgesehen ist. Dieser Verschleißring ist als einteiliger Winkelring ausgebildet, welcher den Boden und die Wand des Taschenradgehäuses schützt. According to the invention it is therefore provided that between the pocket wheel and a replaceable wear ring on the bottom and the wall of the pocket wheel housing is provided. This wear ring is designed as a one-piece angle ring, which protects the bottom and the wall of the pocket wheel housing.

Der Vorteil, der sich durch die Zwischenlage eines derartigen Verschleißringes ergibt, ist einerseits darin zu sehen, daß bei Abrieb oder Verschleiß ein im Verhältnis zum Taschenradgehäuse sehr billiges und überdies leicht auswechselbares Teil betroffen wird. The advantage that results from the intermediate layer of such a wear ring results, can be seen on the one hand in the fact that with abrasion or wear a ratio Very cheap and easily replaceable part for the pocket wheel housing will.

Andererseits ist er in der größeren Betriebssicherheit der unter Einfluß von Druckluft stehenden Maschine zu sehen, da die Wandung des Taschenradgehäuses keine Schwächung erfahren kann. Durch die Erfindung wird gewährleistet, daß bei mangelhafter oder ungenügender Wartung der Maschine kein Zerplatzen des durch Abrieb geschwächten Taschenradgehäuses bzw. Behälters eintreten kann. On the other hand, he is the under in the greater operational security Influence of compressed air standing machine can be seen, as the wall of the pocket wheel housing can experience no weakening. The invention ensures that at Inadequate or insufficient maintenance of the machine no bursting due to abrasion weakened pocket wheel housing or container can occur.

Der auswechselbare einteilige Verschleißring ist auch insofern von Bedeutung, als er durch einen anderen Verschleißring mit dickerem bzw. dünnerem Boden ersetzt werden kann, um bei Auswechseln des Taschenrades gegen eines mit anderem Taschenvolumen ein und dieselbe Betonspritzmaschine für verschiedene Leistungen verwenden zu können. The replaceable one-piece wear ring is also insofar from Significance than it is through another wear ring with a thicker or thinner one Soil can be replaced when exchanging the pocket wheel for one with another Pocket volume of one and the same concrete spraying machine for different services to be able to use.

In der Zeichnung ist ein Ausführungsbeispiel des einteiligen Verschleißringes in einer Betonspritzmaschine dargestellt; es zeigt Fig. 1 einen Querschnitt des Verschleißringes mit den ihn umgebenden Teilen der Betonspritzmaschine und Fig. 2 eine teilweise Draufsicht von Fig. 1. In the drawing is an embodiment of the one-piece wear ring shown in a concrete spraying machine; It shows Fig. 1 a cross section of the Wear ring with the surrounding parts of the concrete spraying machine and Fig. FIG. 2 is a partial plan view of FIG. 1.

Das an der teilweise dargestellten Unterkammer 1 des Behälters angeflanschte Taschenradgehäuse 2 nimmt in bekannter Weise das teilweise mit einer Haube 3 abgedeckte Taschenrad 4 auf, das z. B. durch ein nicht dargestelltes Schneckenrad angetrieben wird. The flanged to the partially shown lower chamber 1 of the container Pocket wheel housing 2 takes the partially covered with a hood 3 in a known manner Pocket wheel 4, the z. B. driven by a worm wheel, not shown will.

Das Taschenrad 4 bildet mit seinen lotrecht verlaufenden Radialwänden 12 sowie mit der Seitenwandung und dem Boden des Taschenradgehäuses 2 Taschen 5. In der in Fig. 1 dargestellten Stellung befindet sich die rechtsseitig veranschaulichte Tasche mit ihrer Auslaßöffnung 6 genau über der Auslaßöffnung 7 des Taschenradgehäuses 2, während die Auslaßöffnung 7 wiederum unmittelbar über der Eintrittsöffnung 8 eines Materialausblasestutzens 9 liegt. The pocket wheel 4 forms with its perpendicularly extending radial walls 12 and with the side wall and the bottom of the pocket wheel housing 2 pockets 5. In the position shown in Fig. 1 is the position illustrated on the right Pocket with its outlet opening 6 just above the outlet opening 7 of the pocket wheel housing 2, while the outlet opening 7 is again directly above the inlet opening 8 a material blow-out nozzle 9 is located.

Nach der Erfindung ist nun zwischen dem Taschenrad 4 und dem Boden des Taschenradgehäuses 2 einerseits und zwischen dem Taschenradumfang und der Seitenwandung des Taschenradgehäuses andererseits ein einteiliger Verschleißring 10 angeordnet, der mit einer Ausnehmung 11 für den Durchlaß des Spritzgutes versehen und leicht auswechselbar eingebaut ist. Er vermag den auftretenden Abrieb beim Betrieb der Maschine aufzunehmen und schützt so das Taschenradgehäuse vor Verschleiß. According to the invention is now between the pocket wheel 4 and the ground of the pocket wheel housing 2 on the one hand and between the pocket wheel circumference and the side wall the pocket wheel housing on the other hand a one-piece wear ring 10 is arranged, which is provided with a recess 11 for the passage of the spray material and easily is installed interchangeably. It is capable of the abrasion that occurs during operation of the Machine and thus protects the pocket wheel housing from wear.
