Abstract:
The seed meter includes the combination of a vacuum housing and a seed disc coupled together in a sealed manner to form a vacuum chamber. Disposed within the vacuum chamber is a generally flat finger wheel having plural radially extending resilient fingers. Also disposed in the vacuum chamber is a fixed arm. A seed hopper is disposed adjacent the seed disc for providing seeds to an outer surface of the seed disc, with the seeds adhering to the plural spaced apertures on the seed disc's periphery with vacuum applied to the disc's inner surface. A rotary drive spindle rotates the vacuum housing, seed disc and finger wheel combination, with each resilient finger sequentially deflected by the fixed arm to sequentially engage each disc aperture, interrupting vacuum communication with each aperture, for sequentially releasing the seeds.
