Abstract

L'invention concerne une structure de rouleau d'alimentation divisée pour une machine d'ensemencement en caisse de culture de semis qui est conçue par stratification et intégration d'une pluralité de plaques de résine unitaires sur un rouleau d'alimentation. Dans la machine d'ensemencement en caisse de culture de semis, le rouleau d'alimentation fonctionne avec des quantités prédéfinies de graines contenues dans ses évidements, transfère les graines en tournant, puis laisse tomber les graines dans une caisse de culture de semis. Le rouleau d'alimentation est un rouleau cylindrique configurant des évidements formés sur sa circonférence extérieure comme des éléments d'alimentation évidés en forme de rainure. Le rouleau d'alimentation est conçu par la stratification d'une pluralité de plaques de résine unitaires en forme d'anneau et ensuite fixe intégralement les plaques. Chaque plaque de résine conçoit, sur sa circonférence extérieure, des rainures comme unité en retrait des parties d'alimentation des éléments d'alimentation évidés en forme de rainure.
