A supply plate has a proximal end supported by a pivot shaft disposed parallel to a position-fixed shaft and a position-movable shaft. A position-movable shaft support member is pressed toward the position-fixed shaft so the first and second rolls are pressed at the contact point under a predetermined pressure. A link arm supported by a fulcrum shaft is pressed to a surface of the position-movable support member that faces the position-fixed shaft. The fulcrum shaft and the pivot shaft are connected. The contact point is shifted as the position-movable shaft support member moves toward the position-fixed shaft, and the pivot shaft is rotated around the axis line by the link arm, the fulcrum shaft, and the link mechanism based on the movement of the position-movable shaft support member, so the slant angle of the supply plate is automatically changed and the supply plate is directed to the contact point.

Grain huller

A grain dropping passage constituted below a husking unit(D) serves as a winnowing room(A). A winnowed grain conveyor() is provided as the sole conveyor below the winnowing room(A). A winnowing wind blown by a winnowing fan(F) through a blowing room(B) passes through below the winnowed grain conveyor() and then rises in the winnowing room(A). The grains mixed with hulls and others are winnowed in the winnowing room(A) so as to be sorted into two kinds: winnowed grains to be received by the winnowed conveyor(), and the other including hulls to be received by a hull conveyor() arranged oppositely to the winnowed grain conveyor() with respect to the winnowing fan(F). In this manner, powerful separation can be executed by means of winnowing wind having a large amount and large speed so as to improve a winnowing ability remarkably.
