  • Patent number: 4810097
    Abstract: A dispensing apparatus is located in the rear of a tip truck body. When the tipping body of the truck is inclined gravity causes bulk material held in the tipping body at either side of a partition to feed augers. The dispensing apparatus includes at least one tank preferably a central tank holding powdered material such as cement powder dispensed through a chute by virtue of a paddle wheel dispenser. Water tanks which dispense water through an outlet are located at either side of the cement powder tank. A common drive shaft drives the augers and the paddle wheel. The dispensing of material is controlled by controllers such that a predetermined ratio of material can be dispensed into, for example a mixer. The dispenser can be used for dispensing the constituents of concrete and may be removable from the tip truck body so that the tip truck can function as a normal tip truck.
