Abstract

The pneumatic distributor is for a single-grain precision seed drill, comprising a housing with a supply mouth and a recess connected to an exhauster creating a vacuum zone. The housing contains a circular rotary assembly consisting of a disc with perforations round the periphery mounted against a wheel. The rotary assembly comprises a stiffening member (9) integral with a hub (19). A disc and a wheel are mounted on the latter, and a selector fixed on the housing slides between the disc and the blades.
