Abstract

Die Erfindung bezieht sich auf eine Dickstoffpumpe, insbesondere eine Betonpumpe, mit einem Materialaufgabebehälter (14), zwei mit ihren stirnseitigen Öffnungen (22) in das Innere des Materialaufgabebehälters (14) mündenden Förderzylindern (10), einem in den Materialaufgabebehälter (14) eingreifenden, mit seinem einen Ende taktweise abwechselnd mit den stirnseitigen Öffnungen (22) der Förderzylinder kommunizierenden und mit seinem anderen Ende an ein Förderrohr (42) angeschlossenen Schwenkrohr (16) und mit einer in der Nähe des schwenkrohrseitigen Endes des Förderrohrs (42) oder in einem außerhalb des Materialaufgabebehälters angeordneten Abschnitt des Schwenkrohrs (16) in der betreffenden Rohrwand angeordneten verschließbaren Reinigungsöffnung (80). Erfindungsgemäß sind die in den Materialaufgabebehälter mündenden stirnseitigen Förderzylinderöffnungen (22) gegen Luftzutritt aus dem Materialaufgabebehälter (14) zumindest teilweise bis in die Nähe des Materialaufgabebehälterbodens, vorzugsweise mittels eines Schiebers (122) abdeckbar oder anschließbar.

Figure 00000001
The invention relates to a thick matter pump, in particular a concrete pump, with a material feed container (14), two conveying cylinders (10) opening into the interior of the material feed container (14) with their front openings (22), and one that engages in the material feed container (14). with one end intermittently alternating with the front openings (22) of the delivery cylinder and communicating with the other end to a delivery pipe (42) connected to the delivery pipe (16) and with one near the delivery end (42) of the delivery pipe (42) or in an outside of the material feed container arranged section of the swivel tube (16) in the relevant tube wall arranged closable cleaning opening (80). According to the invention, the front-side delivery cylinder openings (22) opening into the material feed container can be at least partially covered or connected against air access from the material feed container (14) up to the vicinity of the material feed container bottom, preferably by means of a slide (122).
