Claims

[Claims for Utility Model Registration] Main spiral blades are screwed around the outer periphery of a cylindrical shaft to form a grain-flinging spiral, which is erected within the outer shell to fry grains, and which surrounds the outside of the grain-frying spiral. , in a grain lifting spiral of a grain sorter that sorts grains by a concentrically rotating sorting net, the lower end of the main spiral blade is connected to a lifting tube in a grain receiving tube that receives unsorted grains of the grain sorter. The pitch of the helical blades in the raking and subsequent feeding area of the grain helix is set larger than the pitch in other areas, and the area of the grain helix is provided with an angular position different from the starting end of the main helical blade. At least one auxiliary spiral blade serving as a starting end is provided to locally form a multiple spiral structure, and, following the raking and feeding area, a spiral blade in a portion corresponding to the sorting net body and constituting the sorting area of the grain lifting spiral body is provided. The pitch of the helical blades in the discharge area facing the discharge port of the sorting net at the upper end of the grain frying spiral was increased in the same way as the pitch in the raking and feeding areas. The grain lifting spiral of the grain sorting machine is a feature.
