PROBLEM TO BE SOLVED: To provide a thresher acting bending load on grains by laterally beating ears of grain culm to bump against a net having a proper mesh scale and wire diameter at a high speed so as to increase threshability, to suppress ear cut and to perfectly make grains single ones. SOLUTION: This thresher is characterized by having a forcingly beating rotor giving lateral forced beat to the ears of grain culm nipped and transferred so as to bump against the net of the opposite side. The pitch of the mesh scale is formed to be closer at the ear side than that of stock food side. A winnowing means feeding screening wind under pressure through the mesh is set at the upper side of the net. The forcingly beating rotor comprises the surface of a net structure and is formed to be almost ellipse. A pair of the rotors is set oppositely to each other so as to mutually beat and to mutually receive it in the state nipping the ear parts of grain culms. COPYRIGHT: (C)2006,JPO&NCIPI
