SEPARATOR FOR SEPARATION OF BULKY MATERIALS Russian patent published in 2016 - IPC B07B13/00 

FIELD: agriculture.

SUBSTANCE: invention relates to separation of bulky materials and can be used in agriculture for separation of difficult to separate seed materials. Separator for separation of bulky materials comprises a loading bin, perforated guide, receivers of separation products. Separator is equipped with internal and external cylindrical vertical channels. In the internal cylindrical channel there are steps of working elements, including series-arranged loading bin, wherein the receiving conical shape diaphragm is installed hingedly to the vertical fixed shaft, under which there is feed funnel diaphragm, installed with a possibility of changing curvature radius and fixed to the wall of the loading bin by the upper part. On the inner side of the conical shape diaphragm there are three or more springs, one end of which is fixed to the rod located inside the springs, other end is fixed to the guides mounted on the diaphragm surface. Guides have slots for free passage of rods in them. Perforated guide arranged under the funnel diaphragm, is made in the form of conical accelerating section fixed to the vertical shaft by vertex and by the base it is fixed to the circular concave propulsive surface having the shape of arc in cross section, length of which is 1.0-1.2 of the circle diameter formed by arc rotation. Nonelastic particles funnel-shaped receiver is placed under centrifugal surface, upper part of which is rounded, while the lower part is connected with the second step of the working members. In the area of the propulsive concave surface focal line there is a circular slot for elastic particles, formed by the rounded part of the funnel-shaped receiver and the internal cylindrical channel wall.

EFFECT: technical result - increase of productivity and efficiency of separations.
