(Function) To explain the function of the rotary separator of the hulling machine of the present invention having the above configuration, in the first embodiment, when raw material paddy is supplied to the loading hopper 1, it flows down and flows into the hulling chamber 2, Husking roll 3,
3, and the hulled material flows down the downflow gutter 5 and flows into the winnowing chamber 4.

In the wind selection chamber 4, a sorting air is blown by the action of the suction fan 6 and the pressure fan 31, so the rice husks flow through the discharge pipe 7 and are discharged from the exhaust port 8, and the immature grains collide with the partition plate 11. The immature grains flow into the immature grain receiving trough 10 and are discharged to the outside by a conveyor.

The mixed rice of brown rice and unhulled rice flows into the receiving trough 9, is supplied to the lower inlet of the thrower 14 by the conveyor, and flows into the grain selection section hopper 13 of the grain selection section 12 by the action of the thrower 14.

Among the rice that has flowed into the rotary separator 19 from the supply port 15 of the grain sorting section hopper 13, the brown rice that has been fitted into the pot hole 27 of the rotary separator 19 is fried from below to above by the rotation of the rotary separator 19, forming a roughly V-shaped grain. falls onto the upper surface of the first spiral receiving gutter 22.

The brown rice that has fallen into the recovery spiral receiving trough 22 flows down through the finished rice flow down trough 28 via the discharge trough 26 by the screw conveyor 21, is transferred by the conveyor of the finished rice receiving trough 30, and is taken out by a thrower.
The unhulled rice remaining in the rotary separator 19 is returned to the loading hopper 1 from the discharge port 16 by the screw conveyor 18 of the unhulled rice return gutter 17.

When the work is completed, the switching valve 34 is switched to the temporary line position using a manual lever or the like, and the pressurized air flows from the air passage 33 through the finished rice outflow gutter 28 and the finished rice outflow gutter 26 from the pressure air supply port 35. The air is supplied to the rotary separator 19, and the action of this pressure blows away the residual rice and dust accumulated in the pot hole 27 of the rotary separator 19, and the dust is discharged to the outside of the machine.

The remaining rice is also discharged from the rotary separator 19 and returned to the loading hopper 1 through the discharge port 16 by the screw conveyor 18 of the unhulled rice return trough 17.

Further explaining the second embodiment shown in Fig. 3,
Finished rice flows out from the approximately V-shaped first spiral receiving gutter 22 to the gutter 26
When finished rice no longer comes out, the finished rice sensing valve 42
The finished rice outflow gutter 26 is closed by the action of the operating spring 43, and at the same time, the finished rice sensing valve 42 contacts the limit switch 44 to turn on the limit switch 44. Then, the current to solenoid 39 is cut off,
