Spreader Attachment

摘要

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.

主权项

1. An apparatus for distributing dry, granular materials comprising:
a portable blower for creating an accelerated airflow having an air intake, a motor coupled to a fan for accelerating the airflow, and an outlet for exhausting the accelerated airflow; an elongated outlet tube having an inlet in fluid communication with and connected to the outlet of said blower through which said airflow is delivered, said tube having an exit end through which said accelerated airflow exits; a hopper carried by said tube for feeding an amount of dry, granular material to said tube, said hopper comprising an inlet for receiving said material, and an outlet for delivering said material to said tube; said tube having an opening for receiving said dry material from said hopper and introducing said material into said airflow so that said dry material is mixed with said airflow passing through said outlet tube; and a nozzle in fluid communication with said opening for receiving said dry material from said opening and dispersing it into said airstream, said nozzle extending from said opening into said airstream.
