FIELD: agricultural engineering, in particular, sugar beet seed sowing technique. ^ SUBSTANCE: seeding apparatus has casing incorporating vertical seeding disk having cylindrical portion with through cells for seeds, and ejector positioned in the vicinity of discharge window and made in the form of curved flexible plate with brush. Brush overlaps discharge window at a distance of 0.9-1.1 of its length. Height of brush makes 0.5-0.6 of cell depth. Length of plate is 1.4-1.6 the length of discharge window. Inlet apertures of cells are equipped with flats offset with respect to one another in direction opposite to direction of rotation of disk. Ejector plate may be made from 2-2.5 mm thick organic glass. Brush may be made from polyurethane. Diameter of brush is 0.1-0.2 mm. ^ EFFECT: reduced damage to seeds. ^ 2 cl, 3 dwg |
