A dry particulate spreader includes an attachment assembly for use with a portable hand-held air blower for entraining granular fertilizer, grass seed or similar materials into the discharge air stream of the blower, whereby the particulate is broadcast by the air stream. The attachment assembly comprises an adapter secured to the outlet tube of the air blower which penetrates the outlet tube and introduces a semi-cylindrical nozzle into the air stream. The downstream side of the nozzle is open to the air stream and to the particulate hopper. The air flow around the nozzle creates a low pressure area on the open side of the nozzle. The low pressure induces the particulate contained in a hopper attached to the adapter to enter the air stream. An adjustable valve is provided between the hopper and the nozzle to regulate particulate flow. The adapter is located near the end of the outlet tube of the air blower so the particulate is well mixed in the air stream before exiting the outlet tube.
An apparatus for distributing dry, granular materials comprising:
The apparatus of claim 10 including an adjustable valve for metering said amount of the dry material received from said hopper, said valve being disposed between said hopper and said outlet tube.
The apparatus of claim 11 wherein said adjustable valve comprises:
The apparatus of claim 12 wherein said adjustable valve element comprises a sliding plate.
The apparatus of claim 10 including a bayonet coupling for removably attaching said hopper to said outlet tube including:
The apparatus of claim 14 wherein said nozzle includes an upstream side with a semi-circular profile and a downstream side open to said airstream.
The apparatus of claim 14 wherein said saddle includes a solid sliding plate disposed between said upwardly extending portion and said inwardly extending portion so that said sliding plate may be moved to various positions relative to said opening to vary the opening and said amount of dry material distributed therethrough.
The apparatus of claim 16 wherein a lower side of said solid sliding plate comprises a row of spherical depressions thereon and said saddle comprises a ball-spring detent mechanism situated to mate with said depressions preventing said plate from moving after being set in position.
The apparatus of claim 17 wherein said saddle comprises a plurality of upwardly extending pegs set at an outer periphery of said saddle, said pegs engaging a plurality of flexible elastic straps set around said outlet tube.
