Abstract

Seminatrice pneumatica di precisione con un distributore a disco (13) provvisto di fori (34) e cooperante con un contenitore di semi (11, 15) e con un dispositivo di aspirazione di aria.I fori (34) del disco (13) hanno forma allungata e sezione trasversale ridotta. Un elemento selettore (14) coopera con il disco (13) parzializzando la superficie di aspirazione dei fori.Si ottiene un'ottima separazione dei semi e una deposizione di semi singoli, con semi di diverse forme e dimensioni.
