ABSTRACT:
In a mixing drum (16) of a vehicle mixer is supported a coaxial pipe (24) which together with a closure element (36) and a feeding hopper (42) forms a constructional unit. The pipe (24) is supported by two bearings of the mixing drum (16) so as to be relatively rotatable and longitudinally displaceable. The closure element (36) serves for closing a tail opening (20) of the drum (16) and can be adjusted axially with the central pipe (24) by means of an adjusting device in order to open or close the tail opening (20) of the drum. The pipe (24) extends nearly over the entire length of the mixing drum and ensures the vibration-free bearing of the closure element so that between it and the drum mouth during driving, no relative shifts can occur which would damage the drum mouth sealing. The constructional unit can be pulled as a unit from the mixing drum so that maintenance work can readily be carried out.
