LINE FOR PREPARATION OF SEEDS FOR SOWING INTO SOIL Russian patent published in 2022 - IPC A01F12/44 A01C1/00 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building. Proposed line comprises in-series primary cleaning unit; main cleaning unit; calibration unit; pneumatic sorting unit; pickling unit with low-speed buckets providing non-traumatic transportation of seeds. Line also includes drum separators with non-traumatic wire screens, which represent a rectangular structure curved transversely in the shape of the drum, and consist of multiple transverse and longitudinal rods welded along the perimeter to the wire of the same cross-section and to each other at the points of intersection. Transverse rods function as a base, and longitudinal rods are welded to them from below so that transverse rods rise above longitudinal rods to provide for turning of seeds and direction of their movement along the drum. Bars are made from steel wire with diameter within 2 mm, distance between transverse bars is not more than 30 mm, and between longitudinal bars from 1.7 mm to 12 mm.

EFFECT: line ensures reduction of injuring seeds with simultaneous improvement of cleaning quality.
