Abstract

La présente invention concerne un système de distribution de graines à haute vitesse utilisant le vide ou une autre pression négative pour maintenir les graines et pour séparer les graines dans un compteur de graines (50). Une source d'air à haute pression est utilisée pour déplacer les graines depuis un disque de graines du compteur de graines (50) vers un tube de graines (58) et finalement, vers un champ. Par conséquent, le système est un système hybride comprenant à la fois un compteur de graines à base de vide (50) pour séparer les graines, et un système de distribution à pression positive dans lequel la pression positive est ajoutée pour accroître la vitesse de la distribution de graines. La vitesse accrue de la distribution de graines permet aux graines d'être plantées à des vitesses supérieures, qui peuvent être d'approximativement 16,09 km/h (10 mph) ou plus.
