ABSTRACT:
A mobile concrete mixer comprising an elongated wheeled frame adapted to be connected at its forward end to a prime mover such as a truck or the like to enable the mixer to be moved from one location to another. An elongated conveyor support is pivotally mounted on the wheeled frame and has a hydraulic cylinder operatively secured thereto to enable the rearward end thereof to be raised to the desired dicharge height. A conveyor belt is movably mounted on a conveyor suport and has an elongated concrete mixer hopper positioned thereover. The lower end of the concrete mixer hopper is open to provide communication between the interior of the hopper and the upper portion of the conveyor belt. A plurality of vertically disposed shafts are rotatably positioned within the mixing hopper and have helical conveyor-like portions mounted on the lower ends thereof and laterally extending mixing paddles positioned thereabove. The rotation of the mixing devices elevates and mixes the aggregate materials in the hopper.
