ABSTRACT:
A spreader for granular or powdery material such as fertilizer having three conveyors extending transversally from each side of a hopper for the material, the hopper having two funnels and two discharge ports, one for each funnel, each discharge port being disposed above the inboard ends of a corresponding group of conveyors with each conveyor in each group having different lengths and terminating outboard in a rotary disc spreading member, such spreading members being spaced apart about 2 meters in the two groups of conveyors which are aligned. The conveyors each comprise an endless belt which, through further belts, rotate the spreader members about vertical axes. Disposed between each spreader and the end of the corresponding conveyor is a guide hood which guides the flow of material to the rotary disc behind its flat ejector blades which are biased 60.degree. from a radial line intercepting the inward edge of the blade, so that at design speed the material is ejected through an arc of about 180.degree.. A dosing aperture for each conveyor is defined by a sliding plate under each discharge port, the apertures being generally triangular and movable as a group in the same direction under both discharge ports to meter equal amounts of material onto each conveyor. A closing plate for each sliding plate has three stepped edges whereby the apertures are closed separately and successively commencing with the aperture for the longest conveyor and concluding with the aperture for the shortest conveyor.
