Claims

[Claims for Utility Model Registration] A grain sorting machine comprising a main helical blade on the outer periphery of a helical shaft, which is fitted concentrically and rotatably inside a cylindrical sorting net, and constitutes the main part of a grain sorting machine. , in a grain lifting spiral body in which grains are conveyed upwardly by a main spiral blade from a raking area at the lowest end to a sorting area to a take-out area by rotation of a helical shaft, a grain-lifting spiral body exists almost over the entire area of the grain lifting spiral body. The spiral blade is composed of an inclined part, a stepped part, and an inclined part extending outward from the helical axis, and triangular protrusions are provided on both the inclined parts, and the number of the protrusions is equal to the number of the helical axis. The number of inclined parts closer to the helical axis is greater than the number of inclined parts far from the helical axis, and the convex part is formed with a triangular apex facing the outer periphery, and the inclined part is formed on the inclined part farthest from the helical axis. The angle is made slightly larger than the inclined part near the helical axis, and an auxiliary spiral blade is provided whose starting end is at a different angular position from the starting end of the main spiral blade, so that a multiple spiral structure is formed over the entire area of the grain-lifting spiral, and A grain lifting spiral body for a grain grain sorting machine, characterized in that the auxiliary spiral blade is also constituted by the above-mentioned inclined portion, stepped portion, and inclined portion.
