PRESS WHEEL FOR SEEDS Russian patent published in 2022 - IPC A01C5/06 

FIELD: agricultural equipment.

SUBSTANCE: seed press wheel for seeding devices for precision seeders comprises a solid disc-shaped tire (2) having a central axle for mounting said tire on a hub. In this case, the solid tire (2) contains the first part (7) extending in the radial direction from the said central axis, and the second part (8) extending in the radial direction from the said first part (7). In this case, the first part (7) is made of the first material (7a) having the first value (E1) of the elastic modulus, and the second part (8) is made of the second material (7b) having the second value (E2) of the elastic modulus. The first value (E1) of the modulus of elasticity is greater than the second value (E2) of the modulus of elasticity.

EFFECT: invention makes it possible to increase the efficiency of rolling by more accurate following of the wheel along the relief of the furrow in the ground and by placing the seeds in the required position in the furrow.
