THREE-ROLL FLATTENER OF GRAIN AND GRAIN MIXTURES Russian patent published in 2021 - IPC B02C4/06 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture. A three-roll flattener of grain and grain mixtures is proposed, which includes a drive and kinematically connected upper main, upper side and lower rollers mounted on a frame with the possibility of displacement relative to each other to adjust the gaps between them, a feed hopper with a feed roller and an adjustment flap installed in it, a curved guide plate, cleaning knives. The lower roller of the main flattening zone is simultaneously the drive drum of a belt conveyor with a tensioning device and a driven upper side roller, and the conveyor is located relative to the upper main roller so that, bending around it, the upper part of the belt conveyor and the surface of the main roller form a grain capturing and pinching zone, the conditions for capturing and pinching grain are determined by the thickness and hardness of the belt.

EFFECT: device provides a stable capture of the wet components of the grain mixture and a reliable flow of the production process.
