SEEDING AND SOWING APPARATUS Russian patent published in 2022 - IPC A01C7/00 

FIELD: agriculture.

SUBSTANCE: seeding apparatus (1) for dosing grain products to the soil and seeder containing said apparatus comprise a mechanism (6) for cutting a furrow in the soil, a first assembly for dosing the first grain product, a mechanism (8) for backfilling the furrow, at least one additional dosing assembly for at least one additional grain product. The first assembly for dosing the first granular product comprises the main hopper (10), a first dosing mechanism (18) for dosing the first granular product, in communication with the above main hopper (10), the first means of supplying (19) the first granular product to the soil in the first relative dosing position (P1) formed between the mechanism (6) for cutting a furrow and the mechanism (8) for backfilling the furrow. At least one additional dosing assembly for at least one additional grain product comprises a dosing mechanism. The latter is configured to introduce at least one additional grain product in said relative dosing position (P1) and in another relative dosing position (P2) formed before said mechanism (6) for cutting a furrow, or in another relative dosing position (P3) formed after said mechanism (8) for backfilling the furrow. The additional dosing assembly therein operates jointly with the selection mechanism or contains said mechanism for introducing at least one additional grain product in any of said relative dosing positions (P1), (P2) or (P3), as well as in both said relative dosing positions (P1) and (P2), (P1) and (P3) or (P2) and (P3).

EFFECT: inventions allow for simultaneous application of several grain products in different relative positions, providing a possibility of better and broader vertical, as well as horizontal, dosing of grain products in the soil.
