The cam 42, which is coaxial with the rotation fulcrum 41, rotates,
By pushing the resistance plate 44 fitted on the roll lacan 43, the roll lakan 43 moves laterally. When the roll lacan 43 moves laterally, it is coaxial with the drive shaft of the auxiliary roll 7b, and the shaft 44a
The fulcrum 45 pivots about the pivot point, and as a result, the auxiliary roll 7b moves laterally. Further, when the roll developing lever 41 is rotated from the position of the long hole portion 39a to the short hole portion 39b which is bent, the hulling roll 7a
7b can be fixed in the deployed position.

By the way, the front end of the roll deploying lever 41 is formed so as to be substantially parallel to the short hole portion 39b and to be bent so as to be substantially the same shape, and the roll deploying lever 41 is moved outside the machine body. It is divided at the protruding portion, and a convex portion 50 is formed at the base of the upper roll deployment lever 41a outside the fuselage so as to be along the short hole portion 39b in plan view. A concave groove 51 having the same width as the convex portion 50 is formed at the tip of the lower roll developing lever 41b inside the fuselage so as to extend along the short hole portion 39b in plan view. Further, a U-shaped receiving plate 52 in plan view is fixed upward from the upper portion of the lower roll developing lever 41b inside the fuselage. Further, the upper roll deployment lever 41a and the lower roll

4 and 54 are stretched in the vertical direction, and the upper roll deployment lever 41a is extended.
And the lower roll deployment lever 41b.

During the hulling operation, the roll developing lever 41 is engaged with the concave groove 51 and the convex portion 50 is engaged. Then, as described above, when the worker temporarily suspends the hulling work and resumes the work again, the worker manually moves the roll to the roll development position 40b or the roll development fixed position 40c.
Rotate the roll deployment lever 41 to open the roll gap,
The grains and the like on the hulling rolls 7a and 7b are dropped into the wind selection unit B.
When the work is stored after completion of the operation, the upper roll developing lever 41a is pulled upward, and the lower roll developing lever 41a is pulled up.
1, the upper roll deployment lever 41a is placed sideways in the direction of the long hole 39a. At that time, upper roll deployment lever
The position of the convex portion 41a is fixed by being pressed by the receiving plate 52. Then, the roll deployment lever 41a on the outside of the fuselage covers the long hole portion 39a, and the bent end portion of the upper roll deployment lever 41a covers the short hole portion 39b.

Conventionally, a rat may enter the groove for rotating the roll deploying lever, and there is room for improvement. However, by configuring the roll deploying lever 41 in this manner, the roll is deployed. It is possible to shield the groove for rotating the lever deployment lever, and prevent the mouse from entering the body through the L-shaped hole 39 during storage.
