SOWING DEVICE Russian patent published in 2024 - IPC A01C7/12 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, in particular to devices for sowing loose materials, for example, leguminous crops. Sowing device includes a seed box with a socket installed on the shaft of a two-section coil with grooves, between sections of which there is a separating disc, a seed guide to the lower part of the seed box, a coupling with a rib and a valve. Two-section coil has grooves directed to the centre of the two-section coil and made along a helical line with varying height h. Height h of the grooves of the two-section coil decreases from the edge of the coil to the centre by a value equal to half the height h of the groove of the two-section coil. Grooves of the two-section coil are shifted relative to each other by a distance equal to half the length of the arc l of the section of the two-section coil.

EFFECT: invention will make it possible to improve uniformity of seeds distribution during sowing of various crops on the sowing area, and also to reduce damage of seeds.
