Granular pump

Abstract

A granular pump that includes a dispersion reservoir, a primary reservoir, a manual air pump, and a one-way valve. The user aims the granular pump in the direction of the area to be sprayed with the granular material contained in the granular pump and operates the manual air pump to force a pneumatic pulse through the one-way valve into the dispersion reservoir. The pneumatic pulse into the dispersion reservoir permeates the granular material in the dispersion reservoir and carries the granular material through the second open end of the dispersion reservoir. The velocity of the granular material causes it to spread out in a substantially constant pattern of application. The granular material is continually gravity fed into the dispersion reservoir from the primary reservoir as the user operates the manual air pump while aiming at different locations to be sprayed with granular material until the primary reservoir is empty.
