<p>The proposed vehicle mixer has a mixing drum (16) having on its rear side a drum discharge (20) and on its circumference a revolving rim (18) that is rotatably carried in rollers (14) of a vehicle frame (10) superstructure and the drum discharge (20) is closeable by a closing element (36) with a filling hopper (42), whereby the closing element (36) is mounted slidably on a tube (24) passing co-axially through the drum discharge (20) and supported by the mixing drum (16) between a closing position in which it closes the drum discharge (20) through the mediation of a ring-shaped seal (40), and an open position, whereby it is secured against rotation by a rotation-preventing device and is adjustable by an adjusting mechanism. At the same time the tube (24) forms together with the closing element (36) an integral structural unit and reaches in at least large part of the mixing drum (16) length, which mixing drum (16) has at least one thrust swivel bearing (26) and a sliding bearing (28) for the tube (24).</p> |
