Abstract
A corn and cereal thrasher comprises a cylindrical screen in a vertical casing with an annular space between the screen and the casing. A rotor rotatable concentrically inside the screen comprises successively, from the lower end, a helical screw portion for raising grain to be thrashed, thrashing loops and thrashing blades for thrashing grain raised by the screw and projecting it out through the screen, and a radial fan at the top for raising straw and chaff and discharging them through an opening in the casing. Grain to be thrashed is fed to the screw through an opening at one side near the bottom and the thrashed grain is deflected by an inclined plate to an opening on the opposite side of the casing.
