Abstract

Die Erfindung betrifft ein Misch- und Fördergerät zur Mischung und anschließenden Förderung von Dickstoffen, insbesondere Mörtel und Beton, mit einem Kompressor (3) zur Erzeugung von Druckluft, einem an eine Förderleitung (26) angeschlossenen, ein Rührwerk (13) enthaltenden Mischkessel (14), der mit Misch- und Fördergut beschickt und mit Druckluft zum Austrag der Dickstoffe durch die Förderleitung (26) beaufschlagt werden kann.The invention relates to a mixing and conveying device for mixing and Subsequent promotion of thick materials, especially mortar and concrete, with a compressor (3) for generating compressed air, one to one Conveying line (26) connected, containing an agitator (13) Mixing kettle (14), which loads with mixed and conveyed material and with compressed air to Discharge of the thick matter can be applied through the delivery line (26).

Um bei einem derartigen Gerät die Leistung des Antriebes sowohl während der Mischphase als auch während der Förderphase optimal zu nutzen, den konstruktiven Aufwand, die Herstellungskosten und den Wartungsaufwand zu reduzieren und um die Zuverlässigkeit und Lebensdauer des Gerätes zu erhöhen, schlägt die Erfindung vor, daß der Antrieb des Rührwerkes (13) durch einen oder mehrere Druckluftmotoren (12) erfolgt, die mit einem Anteil der vom Kompressor (3) erzeugte Druckluft versorgt werden.

Figure 00000001
In order to optimally use the power of the drive in such a device both during the mixing phase and during the conveying phase, to reduce the design effort, the manufacturing costs and the maintenance effort and to increase the reliability and service life of the device, the invention proposes that the agitator (13) is driven by one or more compressed air motors (12) which are supplied with a portion of the compressed air generated by the compressor (3).
