[Problems to be Solved by the Invention] However, in such a conventional vertical grain sorter 1, it is troublesome to remove the lower scraping blade 6 each time the sorting net 7 is replaced, and sometimes the mounting is forgotten. However, there was a problem that the tightening was loose and it came loose during operation, resulting in a damage accident.

In addition, there is a limit to the accuracy that can be expected due to the structure, and it is difficult to manufacture the lower scraping blade 6 on the upper surface of the lower partition plate 4 or on the inner and outer circumferences.

The present invention has been made by paying attention to such a conventional problem, and the lower scraping blade for scraping out the small grain is fully filled in the peripheral edge portion of the grain receiving cylinder corresponding to the conventional lower partition plate or the peripheral vertical surface. The purpose is to supply a vertical grain sorter that can be slidably contacted with and orbited around and has no small grains remaining.

"Means for Solving the Problem" The gist of the present invention for achieving such an object is to provide a supply hopper for supplying unsorted grains and a storage tank for storing refined grains outside the body. Inside the shell, a vertical axis for selecting grains by accommodating a fried helix in which spiral blades are wound around the outer periphery of a cylinder and a sorting net body in which the fried helix is concentrically inserted and rotatably held relative to each other. In a type grain sorter, the base of the fried helix is provided so as to surround the base, and the upper end opening has a horizontal peripheral edge that opens outward and has a cylindrical peripheral edge surface, which is not connected to the feed hopper. While providing a grain receiving cylinder that receives the selected grain and supplies it to the fried helix, it is provided between the grain receiving cylinder and the base of the fried helix,
