Patent

CA 2224793

A planter (10) comprises a number of suction cups (30) adapted to be driven around a common horizontal rotation axis in the same sense as any ground wheels present and with zero ground speed at the point of seed-piece ejection from the planter. The variable-length arms (38) carrying the cups at their outer ends result in each cup (30) being displaceable towards and away from the rotation axis to provide a corresponding variation in the peripheral velocity of the cup in dependence on its angular position about the rotation axis.

Une planteuse (10) comporte un certain nombre de ventouses (30) conçues pour être entraînées autour d'un axe de rotation horizontal commun dans le même sens que toute roue porteuse et à vitesse nulle au sol au point d'éjection du planton de la planteuse. Les bras à longueur variable (38) portant les ventouses sur leur extrémité extérieure permettent à chaque ventouse (30) de se rapprocher et de s'éloigner de l'axe de rotation pour assurer une variation correspondante de la vitesse périphérique de la ventouse selon son angle par rapport à l'axe de rotation.
