ABSTRACT:
A self-cleaning counting device for particles such as seeds includes a circular housing have a well pivotally mounted therein for receiving and holding particles from a supply hopper. A disk having a plurality of openings is mounted for rotation in the housing such that the openings move past an open side of the well. A vacuum is applied to the side of the disk opposite the well such that individual particles are partially drawn into the disk openings and are carried thereby to a counting station where the particles are counted. After counting, the vacuum is removed and the counted seeds are released to a discharge chute. When a count is completed, the well is pivotable to a cleanout position where excess uncounted particles are purged from the housing.
