SEEDING DISK Russian patent published in 2023 - IPC A01C7/04 

FIELD: agriculture.

SUBSTANCE: sowing disk (1) for the distribution device of granular material for agricultural machines includes a disk (10) including a number of through holes (12) located around the circumference on its peripheral part, and a counter disk (20) attached concentrically to the disk (10) and having a smaller diameter than the diameter of the disk (10), so that the holes (12) of the disk (10) protrude beyond the outer edge of the counter disk (20). The counter disk (20) has a plurality of in-depth recesses (40) distributed around the circumference near a number of through holes (12) for mixing the seeds located inside the distribution device and directing them to the through holes (12). Each recess (40) is delimited by at least two side walls (32) and a bottom wall (42). In this case, said lower wall (42) is inclined towards the outer side of the sowing disk (1). The counter disk (20) also has a plurality of mixing ridges (33) distributed radially and extending from the central part of the counter disk (20) towards the outer side of the disk (1). In this case, each of these mixing ridges (33) defines the side walls (32) of two adjacent deep indents (40).

EFFECT: improved efficiency of the seeding disk in such a way that it is always capable of delivering only one seed at a time, regardless of its rotation speed or the type of seed, batch of seeds and environmental parameters.
