A transportable tank is disclosed for use as a manure spreader or for distributing foodstuff for livestock in a cattle barn. The tank is adapted to be towed by a tractor and connected the tractor power takeoff through a chain and sprocket arrangement. Shallow conveyor screws are provided on the bottom of the tank and carry the substance therein to the front or rear depending on their direction of rotation. A circular plate is fixed to a hollow shaft connected to the chain and sprocket arrangement and has a plurality of ejection fan blades. Several toothed shredding rotors are disposed radially and mounted for rotation about their respective axes and orbitally about the axis of the circular plate. A planetary gear system with a fixed sun gear is arranged between the rotors and the hollow shaft. The circular plate with its fan blades and the rotors are accommodated in a cylindrical drum mounted about its periphery on rollers. One of the rollers is operable to bring an opening in the side wall of the drum into position so that the fan blades are in selective communication with a closed mixing circuit in the tank for recycling the substance or with the exterior for discharging the substance once it has the desired consistency. |
