ABSTRACT:
A mixing auger apparatus for an on-site mobile concrete mixer is disclosed wherein the mixing auger apparatus is capable of effective operation while oriented at an angle of inclination greater than 22.degree. to the horizontal. The mixing auger apparatus is provided with a flexible housing that extends around the entire circumference of a half flight auger. The flexible housing is suspended from a frame such that the housing is flexible completely around the mixing auger. Adjustment devices allow the positional movement of the flexible housing relative to the mixing auger to modify the clearance between therebetween. The flexible housing is separable to permit movement thereof into an inoperable position to facilitate a cleanout of the mixing auger apparatus. The deployment of the mixing auger apparatus on a mobile concrete mixer permits the use of a standard gravity fed conveying apparatus to deliver component materials to a lower portion of the vehicle with the discharge of a concrete mixture into an elevated chute mechanism which is operable to place the mixture forwardly of the vehicle along a variable range of operation. The mixing auger apparatus is also pivotally supported to provide a range of operation laterally of the vehicle independently of the chute mechanism.
