GRANULAR MATERIALS THROWER Russian patent published in 2008 - IPC B07B11/00 B65G31/04 

FIELD: agriculture.

SUBSTANCE: invention refers to the grain separating and sorting machines used in agriculture for cleaning, sorting, transporting, cooling, drying of grain and byproducts. The granular materials thrower contains the drum consisting of receiving and bearing circular disks, paddles fixed therebetween, loading bunker, and outlet pipe. There is a cone rim mounted on periphery of the bearing circular disk and enveloping endings of the drum paddles. The said cone rim creates clearance of H width with periphery of receiving circular disk. The drum is located with its intake side and clearance of H width in the cylindrical part of the outlet pipe, and with its bearing side with the cone rim outside the outlet pipe. The drum paddles are made from two interconnected parts, the crescent and the inlet part. The first part has a round cone section on its periphery with r radius passing into the cone drum rim, the second one having a rubber-covered working surface and being fixed on the disk at angle α to drum radius.

EFFECT: device allows for increasing treatment and cleaning efficiency of the material as well as for decreasing damaging the granular material and simplifying design.
