Abstract
A continuous mixer that is installed in the bed of a dump truck. The mixer has a hopper for cement, a pair of belts to move the other mixing materials, and a chute with an auger for mixing the cement and mixing materials with water and depositing the mixture where desired. The hopper stands upright in the bed when the bed is down and tilted at about 45° when the bed is up. An auger at the bottom of the hopper feeds cement to an opening at the bottom of the hopper, The belts sit below the hopper and are oriented with the belts parallel to the ground during operation, The belts feed mixing materials from the bed to a mixing chute below the belts. An auger combines the dry materials and water to form the concrete as they travel the length of the chute to the discharge end.
Claims11
A mobile continuous mixing apparatus adapted to be received by the bed of a dump truck, the apparatus comprising:
- (a) a hopper designed to hold cement and having a bottom and front wall;
- (b) a rotating hopper auger assembly at the hopper bottom designed to move the cement toward an opening in the bottom of the hopper;
- (c) a pair of feed belts within a belt housing below the hopper and designed to be open to the truck bed, the belts extending in a direction parallel to the hopper front wall, linearly aligned, and separated by a gap aligned with the opening in the hopper, the belts designed to feed materials from the truck bed to the gap where the feed materials fall to a feed opening that is below and aligned with the opening in the hopper;
- (d) a chute having a pivot end and a discharge end, the chute comprising an elongated trough and a rotating mixing auger within the trough, the chute mounted to pivot vertically about the pivot end between a storage position, wherein the discharge end is higher than the pivot end, and a discharge position, wherein the discharge end is at or lower than the pivot end, the chute having a materials inlet at the pivot end below and aligned with the feed opening, a mixture discharge opening at the discharge end, a water inlet into the trough, the chute auger designed to mix and move materials from the materials inlet and the water to the discharge opening;
- and
- (e) drive mechanisms for rotating the hopper auger assembly, feed belts, and mixing auger.
