成果简介	NOVELTY - The seeding unit has a seed hopper, a seeding wheel, two coaxial drums such as a fixed drum (1) and a rotary drum (2), and sealing elements (3) of the seeding wheel that are located along the circumference on a periphery of the rotary drum. The metering and seeding openings in an annular section (5) of the fixed drum are made in the form of an oblong groove (8) with wedge-shaped edges of length that is equal to 1/4 of the length of the circumference of the corresponding ring of the fixed drum. A surface of a cellular ring of the rotary drum has teardrop-shaped depressions on the inside. The outside of a cell (4) has an extension in the form of a chamfer. The sealing elements of the seeding wheel are made in the form of pincers in shape repeating a lower portion of a cycloid loop. USE - Seeding unit for sowing seeds under mulching film. ADVANTAGE - The reliability of the sowing apparatus is increased, so as to ensure a compacted seed bed at the bottom of the hole when sowing under mulching film and eliminates the crumbling of soil into the resulting hole and uneven placement of seeds in the hole. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a seeding apparatus for sowing seeds under a mulching film. 1Fixed drum 2Rotating drum 3Sealing element 4Cell 5Annular section 8Oblong groove
