Abstract

Distributeur pneumatique de matières granulées. Un appareil, destiné à distribuer pneumatiquement des matières granulées, à partir d'une trémie 44, comprend un tube d'arrivée d'air comprimé 62 qui débouche dans le fond de la trémie 44 et un tube transporteur 66 dont l'embout d'entrée 70 est légèrement écarté axialement de l'extrémité du tube 62. Une couronne 108, alimentée en dérivation par le tube 62, souffle de l'air par des trous 110 vers l'espace compris entre la susdite ouverture et l'embout 70. Application : distribution de produits chimiques le long de lignes de semis, par un semoir à lignes multiples.
