   Die Erfindung betrifft Betonmischmaschinen mit zweiteiliger Mischtrommel, deren Teile achsial gegeneinander verschiebbar sind. Bei diesen Betonmischmaschinen wird die Achsial-

 samen Welle verschoben wird. Da die den beiden Trommelbälften   gemeinsame   Welle innerhalb des   Mischraumes     ständig von   dem nassen Betongemisch umgeben ist, so wirkt dieses auf Welle und Nabenbohrung bei der Hin-und Herbewegung der einen Trommelhälfte auf der gemeinsamen Welle wie ein Schleifmittel und beide, Welle und Nabenbohrung, sind einem   ungewöhnlich   schnellen und starken Verschleiss ausgesetzt, der oft so weit geht, dass das Betongemisch zwischen Nabe und Welle hindurchtritt,

   beide   Trommelhälften   infolge der durch den   Verschleiss gestörten   achsialen Lagerung an ihren   Umfängen   nicht mehr   schliessen und auch hier der Trommelinhalt     vorzeitig ausfliesst.   



   Diesem Nachteil soll durch die vorliegende Erfindung vorgebeugt werden. zu welchem Zwecke an der Teilung der Trommel auch die Welle teilnimmt, so dass jed. Trommelhälfte auf

  Concrete mixer with two-part mixing drum.



   The invention relates to concrete mixers with a two-part mixing drum, the parts of which are axially displaceable relative to one another. With these concrete mixers, the axial
 EMI1.1
 seed wave is shifted. Since the shaft common to the two drum halves is constantly surrounded by the wet concrete mixture within the mixing chamber, this acts on the shaft and the hub bore when the one drum half moves back and forth on the common shaft like an abrasive and both shaft and hub bore are one exposed to unusually fast and severe wear, which often goes so far that the concrete mix passes between the hub and shaft,

   Both drum halves no longer close at their circumferences due to the axial bearing disturbed by the wear and here too the drum contents flow out prematurely.



   The present invention is intended to prevent this disadvantage. for whatever purpose the shaft participates in the division of the drum, so that each. Drum half open
 EMI1.2
   the drill hole is closed inwards by a protective cap-like extension.



   The invention is shown in the drawing, namely show:

   2 shows a section through an embodiment of the mixing drum,
3 shows the section of a second embodiment,

Claims (1)

dass die Trommelhälfte b ihre Längsverschiebung ungestört ausführen kann, wie in Fig. 5 dar- gestellt ist. PATENT-ANSPUCH: Betonmischmaschine mit zweiteiliger Mischtrommel, deren Teile achsial gegeneinander verschiebbar sind. dadurch gekennzeichnet, dass zwecks Verringerung des Verschleisses von Welle und Nabenbohrung der achsial verschiebbaren Trommelhälfte jeder Trommelteil auf den einandet zugekehrten Enden einer geteilten Welle gelagert ist. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. that the drum half b can carry out its longitudinal displacement undisturbed, as shown in FIG. PATENT CLAIM: Concrete mixer with two-part mixing drum, the parts of which can be axially displaced against each other. characterized in that, for the purpose of reducing the wear on the shaft and hub bore of the axially displaceable drum half, each drum part is mounted on the ends of a split shaft facing one another. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
