GRINDING DEVICE Russian patent published in 2018 - IPC A01D43/10 

FIELD: agriculture; machine building.

SUBSTANCE: re-grinding device 1 for grinding the harvested crop comprises at least two rollers 10 and 20, rotation axes 11 and 21 of which are parallel to each other. Each of rollers 10 and 20 comprises axes that are axially interchangeable and are oblique. Straight sections are provided with a peripheral surface extending parallel to the rotation axis 11 and 21 of the roller 10 and 20. Obliques have a peripheral surface extending at angle to the axis of rotation of the roller 10 and 20. Straight portion of one roller 10 and 20 corresponds to the straight portion of the other roller 10 and 20, forming between their opposite peripheral surfaces a parallel rotation axis 11 and 21 for grinding the crop harvested. Oblique portion of one roller 10 and 20 corresponds to the oblique portion of the other roller 10 and 20, with the formation, between their opposite peripheral surfaces, of opening at angle to the axis 11 and 21 of the gap for grinding the crop harvested. End face of one roller 10 and 20 corresponds to the end surface of the other roller 10 and 20, with a radial cutting gap between them to handle the harvested crop.

EFFECT: group of inventions improves quality of the prepared crop for further use.
