Cone-cylinder-shaped variable-size hole hundred-grain plate

The utility model discloses a conical-column-shaped variable-size hole hundred-grain plate, and belongs to agricultural machinery. The movable plate is fixedly mounted on the bottom plate with the handle fixedly mounted at the upper end in a threaded connection mode through screws penetrating through U-shaped holes formed in the movable plate and threaded holes formed in the movable plate, the conical protruding blocks on the movable plate are matched with the rectangular notches between the barrier strips in a transverse moving mode, and 100 variable-volume holes are formed by the semi-conical column holes between the conical protruding blocks and the barrier strips. According to the utility model, the relative position between the movable plate and the bottom plate is changed by transversely moving the movable plate, and the size of a hole formed by the semi-conical cylindrical surface and the barrier strip is steplessly regulated and controlled so as to adapt to different crops or different varieties of th
