Abstract

L'invention concerne un mécanisme pour interrompre le flux de graines dans des doseurs de graines sous vide. L'objet de la présente invention vise à résoudre les inconvénients décrits dans l'état de la technique par le biais d'un mécanisme (10) qui agit dans des trous des disques sélecteurs de graines, poussant et scellant parallèlement l'orifice d'aspiration ou de pression, lesdites graines étant amenées à tomber en retour dans le réservoir sans tomber sur le sol, évitant le débordement lors de l'ensemencement avec une diminution des coûts liés aux graines, une meilleure répartition des plantes dans le sol et une augmentation de la rentabilité. Le dispositif (10) peut être actionné de manière électrique, pneumatique, hydraulique ou mécanique agissant sur le côté opposé des graines du disque sélecteur au moyen d'une roue (15) dentée qui entre dans les orifices du disque sélecteur. Lorsqu'il est déconnecté, le mécanisme est rattaché au disque sélecteur et n'interfère pas dans le fonctionnement du doseur. Avec ce mécanisme, il est possible de commander chaque ligne indépendamment par le biais du plan de plantation avec un coût de fabrication et de manutention bas favorisant la diminution du coût des graines par absence de gaspillage et amélioration de la productivité par une meilleure disposition des plantes lors du labour.
