Claim:
A particle spreader system, comprising: a manifold including sidewalls and an upper end, said upper end having an intake opening and said sidewalls having a plurality of discharge openings extending therethrough, wherein said upper end of said manifold suspendedly attaches to a storage bin adjacent to an inlet; wherein said inlet is adjacent to said intake opening; wherein said manifold includes a plurality of slots adjacent each of said discharge openings, wherein said plurality of slots are incrementally spaced in a vertical manner and wherein said plurality of slots extend through said sidewalls; wherein said manifold includes a plurality of channels vertically oriented and extending through said sidewalls, each said channel is adjacent a group of said plurality of slots; a plurality of gates slidably attached to said manifold, wherein said plurality of gates selectively cover said plurality of discharge openings; a plurality of adjustment devices attached to said plurality of gates, said plurality of adjustment devices each extending through a respective said channel from an exterior side of said sidewalls to an interior side of said sidewalls and each said channel is adapted to extend through one of said plurality of slots, said interior side adapted to receive a mass of particles; wherein said plurality of adjustment devices incrementally extend within said plurality of slots to adjust a relative vertical position of said plurality of gates with respect to said plurality of discharge openings to regulate a flow of a mass of particles therethrough; wherein each said adjustment device has a spring retained upon said adjustment device on said exterior side of said sidewalls and has a hook-shaped securing portion adapted to extend on said interior side, said spring provides a biasing force upon said adjustment device to force said hook-shaped securing portion within one of said plurality of slots and toward said exterior side of said sidewalls; and a plurality of chutes attached to said manifold, wherein said plurality of chutes extend outwardly from said plurality of discharge openings.
