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.
