VIBRATION MACHINE FOR PRE-TREATMENT OF SEEDS Russian patent published in 2016 - IPC A01C1/00 

FIELD: agriculture; machine building.

SUBSTANCE: vibration setting for pre-treatment of seeds contains grinding drum unloading window, hopper, the unloading chute mounted elastically on the ground. Grinding drum is made conical, fixedly mounted horizontally and is mounted in three or more bands of trapezoidal shape with different widths, increasing their length, which are alternately of opposite sides with an angle of 60° to the axis of the bands are formed by milling or zones of reduced pressure treatment section in the form of cuts with sloping walls to form the perimeter of the conical screw grinding drum polyhedral surfaces alternately arranged with their lateral sides of the triangles. Bands are twisted in a longitudinal direction relative to its longitudinal axis and bent in a transverse direction along a helical line on the tapered mandrel to form the perimeter of the screw of the grinding drum three or more helices and helical surfaces of the main and opposite directions with varying, increasing pitch helical lines.

EFFECT: device allows you to simplify the design and expand its technological capabilities.
