ABSTRACT:
A seed dispensing device comprising a housing in which is rotatably mounted a wheel member having a plurality of spokes each carrying a seed cup. The cups pick up seeds from a reservoir on rotation of the wheel member and under the combined action of centrifugal and gravitational forces discharge the seeds to an outlet chute. Opposed brushes are provided in the housing between which the cups pass to sweep excess seeds from the cups and to aid retention of a single seed in each cup to the discharge point. A rotatable cleaning brush element having tangential bristles is mounted in the housing to clean cups prior to the cups entering the mass of seeds in the reservoir. Further brushes and excess seed catching gutters may be provided to assist the reliability of solely a single seed being discharged at predetermined intervals. A power-operated ejector may be arranged to discharge foreign matter or broken seeds and so on from the reservoir.
