DEVICE FOR DRY CLEANING OF TUBEROUS ROOTS FROM SOIL IMPURITIES Russian patent published in 2024 - IPC A01D33/08 A23N15/00 

FIELD: agriculture.

SUBSTANCE: device comprises a frame with a semi-cylindrical hopper, an unloading auger with an electric drive through a belt transmission and four fixed brush assemblies. Frame and semi-cylindrical hopper represent a whole welded metal structure. Inside the cylindrical hopper there is a limiting grid, in the centre of which there is a rectangular hole for passage of tuberous roots. Limiting grid is installed in semi-cylindrical hopper above U-shaped cross-shaped drum so that its inclined walls provide smooth and uniform sliding of tuberous roots. U-shaped cross-shaped drum rotates in bearing supports from geared motor through gear transmission, which is closed by casing. Unloading auger is located in the casing at an angle, and its lower and upper output ends of shafts rotate in bearing supports. In the lower part of the unloading auger and the casing there is a window for removal and subsequent return of the fertile soil layer into the field, and in the upper part there is a blade for ejection of washed root crops. Brush assemblies are arranged inside a clover-shaped housing and consist of a fixed shaft on which cross-shaped finger pile brushes are installed through spacers. Pile brush finger height is made up of unloading auger diameter minus its shaft diameter.

EFFECT: increasing operational reliability, increasing productivity and increasing the degree of purification of tuberous roots.
