ABSTRACT:
An auger swivel for a concrete mixer includes a channel mounted to a bowl. A center member is pivotally connected to a pivot point near the channel and near an outer surface of the bowl. The center member includes a pair of first wings that extend from the pivot point, opposite each other and away form the bowl. Two slides are received in the channel and are positioned away from each other by a ring. Two second wings are provided. One of the second wings is pivotally connected to one of the first wings at one of its ends and pivotally connected to one of the slides at its other end. The other second wing is similarly connected to the other first wing and the other slide. An actuator rotates the center member about the pivot point and causes the slides to rotate around the outer surface of the bowl and about a longitudinal axis passing through the bowl.
