TUBEROUS ROOT CLEANER FROM SOIL AND FINE FRACTION Russian patent published in 2024 - IPC A01D33/08 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building. Cleaner contains rollers (2) made in the form of spirals with an equal winding pitch and mounted on frame (1), made sliding with the possibility of changing its width and fixation. Rollers are made with possibility of rotation in one direction. Winding direction of spirals of even and odd rollers is made in opposite directions, and the ends of which are rigidly fixed on bushings (3) installed symmetrically inside frame (1) on both sides of rollers (2), connected to each other through chain (4) by sprockets (5). Sprockets (5) of even and odd rollers (2) are installed outside frame (1) with the possibility of rotation of even and odd rollers (2) in one direction and through chain (4) are connected to drive (6) installed on frame (1) with an adjustable rotation frequency. Between rollers (2) and sprockets (5) there are cams (7) located inside frame (1). Shafts (8) of even and odd rollers (2) are rigidly fixed on vertical planes (9) of their cams (7) with displacement by the same value relative to their centres and turned relative to each other by 180°, and in opposite vertical planes (10) of these cams (7) in their centres are rigidly fixed shafts (11), which are installed in bearing supports (12) and are connected on one side with sprockets (5). Central axes of shafts (11) coincide with central axes of sprockets (5).

EFFECT: higher quality of tuberous roots treatment.
