THROWER OF LOOSE MATERIALS Russian patent published in 2012 - IPC B07B11/00 B65G31/04 

FIELD: process engineering.

SUBSTANCE: invention relates to grain cleaning and sorting machine, the so-called grain throwers, in agriculture. Proposed machine comprises encased drum made up of bearing and circular disks and blades secured there between, loading bin, discharge branch pipe and frame. Screens with 6 mm-dia round mesh screens are mounted ahead of blade front surface at some 50 mm therefrom. 30 mm-high opening with flexible valves are arranged behind said screens. 30 mm-long accumulators of light impurities are mounted behind said openings and perpendicular thereto. Drum blades consist of three parts, i.e. working, front and rear. Blade front surface is mounted at 30° drum radius running through blade start, while blade working and rear surfaces feature inclination of 25° and 45° to front blade plane.

EFFECT: higher efficiency of cleaning, reduced damages of grain.
