A dosing device (1) for sprinkling granules (2) comprises upper elements (3) which delineate a storage space (4) for the granules, and lower elements (5) with a portion (6) which forms the bottom (6a) of the storage space and is provided with delivery apertures (7) for the granules. For rapid and even distribution of the granules (2), the delivery apertures (7) are distributed along the whole surface of the portion (6) of said lower elements (5) which forms the bottom (6a) of the storage space (4), and said lower elements comprise a dosing arrangement (8) in the form of a delivery element (9) which surrounds the delivery aperture, runs upwards in the storage space and is provided with an upper inlet aperture (10) and a delivery duct (11), and of a hoodlike element (12) which covers the delivery element, narrows upwards in the storage space, delineates between itself and the delivery element a flow duct (13) and runs to the vicinity of the bottom of the storage space, the section (4a) of the storage space which is situated radially within an imaginary downward extension of the hoodlike element being in communication with the delivery aperture so that granules in that section, upon rapid vertical and/or substantially vertical movements downwards, are guided in by the flow duct to above the inlet aperture of the delivery element in order to be able, via the inlet aperture, to fall through the delivery duct of the delivery element to the delivery aperture. |
