Abstract
A distributing unit (10) for granular material such as seed grains (12), fertilizers or the like is disclosed, in particular a seeding unit (11) of a distributing or seeding machine. The unit (10) comprises a housing (14) with at least one inlet opening (18) for conveying granular material or conveyed seed grains (12) and an outlet opening (26) and also a rotating conveying device (24) with at least one rotating conveying element (28) for taking hold of the granular material or the seed grains (12), which conveying element is arranged or extends approximately axially with respect to the housing (14). The grains are held by centrifugal forces on an inner lateral surface region (16) of the housing (14), are crowded together there and are aligned with respect to one another and are ordered in a line or are rowed at an angle which corresponds to an angular position between the lateral surface and the radial conveying element (28), with the result that in each case only one single grain (12) at the end of the row extends in a predefined path along the lateral surface (16) and, at the end of the separation process, leaves the outlet opening (26) approximately tangentially.
