SEED DISTRIBUTOR Russian patent published in 2022 - IPC A01C7/20 

FIELD: agricultural engineering.

SUBSTANCE: seed distributor contains a seed box with a socket, a four-section coil with gutters having a shape of part of a tor rotation surface, installed on a shaft, made as a single whole of plastic of increased strength, a guide rail for directing seeds to a lower part of the seed box, a coupling with a rib, a valve, and separating discs in the form of partitions. A shape of ribs and a shape of a profile of gutters of the section coil are made according to a shape of ribs and a shape of a profile of gutters of a screw coil. Ribs and gutters of four sections of the section coil with gutters are inclined towards the middle of the section coil, while an angle α of inclination of gutters and ribs of the section coil is equal to 18…22 degrees. Separating partitions, along a direction of movement of the seed distributor, close from a left side of sections, along a contour of gutters, gutters of sections of the section coil with gutters. At the same time, partitions are made flush with a side surface of sections of the section coil with gutters, and their free part located at a level of an outer surface of ribs of the section coil coincides with a contour of an outer cylindrical surface of the section coil. In this case, gutters of a right side section of the section coil, along the direction of movement of the seed distributor, are similarly closed with partitions and from the right side. A thickness of partitions is equal to 0.4…0.5 mm, a working length L of the section coil with gutters is equal to a working length of a standard coil with gutters, and a length of the rib of the section of the section coil with gutters is more than a thickness b of the section of the section coil with gutters.

EFFECT: invention provides an increase in the uniformity of sowing seeds.
