A seeding unit is made as a tubular rotor (a roll) on the outer cylindrical surface of which tubular seeding fingers (for example in a staggered or another order) are fixed by rows. While pressing said seeding fingers into soil, seeds are ejected therefrom and pressed into soil at the depth equal to the height of said fingers. The above-mentioned tubular rotor (a roll) has side bearing assemblies and rolls along the surface of the field. Each sowing finger is made as composite one and has a thread bush with an axial opening for passing seeds, an axial opening for an ejecting rope and a radial opening connected with a seed opening of a tip, in which a rubber washer with a central opening no larger than the size of the smallest seeds, through which the seeds are ejected, is mounted, and an outer threaded coupling, connecting the bush with the tip, in which there is a radial opening. While turning the bush, it can coincide with a radial opening in the bush while the seeds are pouring and not coincide in the working state. |
