Abstract
A vacuum seed metering mechanism arranged in combination with a seed hopper for uniformly dispensing seeds to the ground. The seed metering mechanism comprises a rotational distributor disc provided with a circular row of openings toward a periphery of the disc. The disc carries seeds from a seed reservoir to a seed discharge area under the influence of pressure differential. The disc is rotatably mounted in a housing whose interior is divided by the seed disc into the seed reservoir, on one side of the seed disc, and a suction chamber, lying around a portion of the path of movement of the openings in the seed disc. A salient feature of the present invention relates to the provision of an apparatus for imparting vibrations to the housing for facilitating the release of seeds from the openings in the disc in the discharge area of the seed.
