Abstract

L'invention concerne un doseur de graines comportant une courroie sans fin en tant qu'organe de transport de graines avec un différentiel de pression pour maintenir la graine sur la courroie. L'utilisation d'une courroie sans fin comme organe de transport de graines permet à l'orientation spatiale de l'organe de transport de graines de varier d'un emplacement à l'autre le long du trajet de la courroie où différentes fonctions de dosage de graines sont réalisées. La courroie permet une plus grande liberté lors de la détermination de l'emplacement de la région de collecte de graines et de la région de libération ou d'enlèvement de la graine au-delà des contraintes d'un disque à graine de diamètre fixe. La courroie permet en outre de mettre à disposition un doseur de graines d'enveloppe étroite qui peut délivrer les graines de façon croisée dans un dispositif de délivrance orienté de manière sensiblement verticale.
