Description of the Related Art Conventionally, a pair of left and right hulling rolls, a wind selecting section for wind-selecting the slide-out paddy slid by the rolls, and a swing for separating the wind-selected slide-out paddy into paddy rice and brown rice A hulling device including a type sorting unit is known.

[0003]

Since the hulling roll a of a known hulling device is usually horizontally laid horizontally (see FIG. 1).
However, since the slide-out paddy vertically descends at a furious speed, it collides with one of the lower parts b and bounces back, which adversely affects the wind selection effect. Further, the hulling roll a shown in FIG. 1 is not suitable as a product for overseas markets in which the rolls cannot be easily exchanged because of its severe wear. In this regard, in the inclined roll disclosed in Japanese Patent Publication No. 3-23231, which is separately known, since the sliding-out paddy is discharged obliquely downward, the sliding-out roll is slid out to the wind-selecting portion having a zigzag-folded structure in a small scattering state. Since it can supply paddy, not only can the wind selection effect be improved, but according to experiments, it has been recently proved that the paddy roll is less worn and has durability, making it suitable as an overseas product. .. Further, looking at the conventionally known rocking type sorting section, all of them are of the tilt rocking type, so that there is a problem that there is much vibration. Inclination rocking is Shokoku Sho 5
As described in JP-A 7-9872, a selection plate c
Is slanted in the vertical direction to sort out the heterogeneous mixed particles on the plate surface (see FIG. 2). Normally, 5 or more sorting plates c are superposed. When it is swung up and down obliquely by d, vertical vibration is generated and cannot be eliminated. Moreover, since the grain jumps, it is not good to sort the grain by tilting up and down.
