Kind Code:
A
Abstract:
A dosing apparatus for granular or powder material, e.g. in connection with a seed drill, comprises a feeding-out device which is rotatable about a normally vertical axis and which, by the action of the centrifugal force, flings out supplied material from a central area so that the material is fed out through a number of outfeed openings. The feeding-out device comprises first and second, concentrically disposed outfeed means (51, 52) arranged to rotate with mutually different speeds and having cooperating parts (65, 66 and 58, 78) which, by relative speed difference between said parts, move the thrown-out material out from suitable openings (70). The first outfeed means (51) comprises a pair of peripherally extending shielding walls (65, 66) having respective outfeed openings (69 resp. 70) which are mutually displaced along the circumference and which, together with a boundary wall (58) of the second outfeed means (52), define an outfeed compartment (71).
