Claims

[Claims for Utility Model Registration] Consisting of a helical shaft with a helical blade on the outer periphery, the grain sorting machine is fitted concentrically and rotatably inside a cylindrical sorting net to constitute the main part of the grain sorting machine, In a grain lifting spiral body that uses spiral blades to transport grain upward from a raking area at the lowest end to a sorting area to a take-out area by rotating a spiral shaft, on the upper surface of at least a portion of the spiral blade existing in the sorting area, It consists of convex parts arranged at intervals of 100 to 250 mm, and the circumferential width of the convex parts is equal to 2 times the short axis of the grain.
~6 times, and the protruding height is equal to or about twice the breadth of the grain, and the protrusion has a length from the outer periphery of the spiral blade to about twice the breadth of the grain. In the inside position,
What is claimed is: 1. A grain lifting spiral for a grain sorting machine, characterized in that the grain lifting spiral is arranged so that its outer peripheral end is positioned.
