Rotary mixing apparatus

An apparatus for weighing, mixing, and transporting a mixture of dry granular or wet materials, and which is characterized by the materials being simultaneously mixed and transported, and comprising

• a trackway including a pair of parallel, laterally spaced apart rails, with said trackway defining a receiving end portion and a discharge end portion, and with said receiving end portion being physically unconnected to the remaining portions of said trackway,
• a mixing container adapted for receiving the materials to be mixed and including a peripheral outer wall comprising a plurality of flat wall sections, opposite parallel end walls, a door positioned in said peripheral outer wall, axle means fixedly mounted to each of said end walls and extending coaxially outwardly therefrom so as to define a central axis, and wheel means fixedly mounted to each of said axle means and operatively engaging respective ones of said rails of said trackway, and such that the container may be moved along said trackway while being rotated about said central axis,
• weighing means operatively connected to said receiving end portion of said trackway for permitting the container and its contents to be weighed when said container is disposed on said receiving end portion,
• means for moving the container along said trackway between said receiving end portion and said discharge end portion, and
• mixing vane means mounted within said container for facilitating the mixing of the materials during the rotational movement of said container along said trackway, said mixing vane means including a plurality of flat blades mounted in spaced relation to the inside surface of said container outer wall, and with at least a plurality of said wall sections mounting at least one pair of said flat blades, and with the blades of each such pair being separated from each other and oppositely inclined with respect to the axial direction,
• whereby the container may be filled with weighed amounts of each of plurality of different materials while positioned on said receiving end portion of said trackway, and then moved along the trackway to said discharge end portion to effect concurrent mixing and transport of the materials, and the mixed materials may be discharged upon the container reaching the discharge end portion.
