<p>The seeder has a depression chamber (1) sealed by a dispensing disk (10). The chamber and the dispensing disk are integrated in rotation around an axis (X). The dispensing disk separates the depression chamber from a seed tank (3) and comprises a series of holes formed regularly in a periphery of the disk. Each hole aspires a seed contained in the tank and maintains grain plated against the dispensing disk. An exerting unit (5) exerts constraint on an obturating disk (4) to maintain the obturating disk in a support against the dispensing disk along an angular portion.</p> |
