Abstract:
A seed meter for a seed planter, comprising:a drum having an interior chamber in communication with a vacuum source, said drum further having an exterior circumferential periphery with a plurality of spaced apertures therethrough in communication with said interior chamber; a shaft rotatably supporting said drum such that at least a portion of said exterior circumferential periphery of said drum is in communication with a seed reservoir through which said apertures succeedingly rotate, wherein seeds in said seed reservoir become entrained over said apertures as a result of a lower atmospheric pressure within said interior chamber created by said vacuum source; at least one seed stripper disposed above said exterior circumferential periphery of said rotatable drum for removing any seed multiples entrained over any one of said apertures; a seed release disposed within said interior chamber over which said entrained seeds succeedingly rotate, said seed release succeedingly blocking said lower atmospheric pressure thereby succeedingly releasing the seeds entrained over said apertures.
