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 field grain lifting spiral body in which grains are conveyed upward from a raking area at the lowest end to a take-out area via a sorting pond area by a main spiral blade by rotation of a helical shaft, a spiral at the lowest end of the main spiral blade; The pitch is set larger than the pitch in other areas, and an auxiliary spiral blade whose starting end is at a different angular position from the starting end of the main spiral blade is provided in the enlarged view of the pitch to form a locally multiple spiral structure. Further, the auxiliary spiral blade and the lower main spiral blade are provided with a protrusion extending from the tip of the blade to the helical axis, and a convex portion is provided on the upper surface of at least a portion of the main spiral blade that exists in the sorting area. A grain frying spiral for a grain sorter, characterized in that the distance d between the outer diameter _D1 of the spiral blade and the inner diameter _D2 of the grain receiving tube is approximately equal to or slightly larger than the minor axis of the rice grains.
