Then, the paddy is supplied from the paddy tank 2 to the husking section 1, the supplied paddy is subjected to the husking action, the husks are sorted by the hushu rice wind sorting path 4 below, and the rice husks are taken out of the machine from the dust exhaust pipe 6. It is discharged. For mixed rice of brown rice and paddy, the amount of dropped rice @ 7
The fried mixed rice 818 is lifted up and supplied to the starting end of the supply gutter 14 on the rotary sorting tube 11 side, and then supplied to the supply side end of the rotary sorting tube 11 by the supply helix 13 in the feed gutter 14. .

The mixed rice is then pumped up through the pot hole of the rotary sorting cylinder 11, which is rotating clockwise in FIG.

Fine-grained brown rice falls into the finishing rice gutter 16, and mixed rice including paddy and some brown rice falls into the supply @14 where it is sorted and sent to the feed gutter 1.
The unsorted mixed rice that has fallen into the feed helix 13 is fed again into the rotary sorting tube 11 from the conveyance terminal end of the feed gutter 14 and is resorted.

Further, the finished rice that has fallen into the finishing rice gutter 16 is conveyed to the finishing rice flow lower cylinder 17 by the finishing rice helix 15, and is transferred to the finishing rice flow grain plate 18.
While falling to the finished rice volume @ 19, it is sorted by a sorting wind and taken out of the machine by a finished rice lifting machine 20.

The sorted paddy sent to the discharge side end of the rotary sorting cylinder 11 is
The paddy enters the pumping cylinder 22, is pumped up by the pumping cylinder 22, falls into the upper paddy return gutter 22, is returned to the shedding section 1, and is again subjected to the shedding action in the shedding section 1.

As mentioned above, during the sorting work of mixed rice, the brown rice pumped up high through the pot hole of the rotary sorting cylinder 11 is classified as finished rice 4.
The unhulled rice that falls into the i116 and is drawn up low falls into the rotary sorting tube 11.

In addition, although the rice was pumped up relatively high by the pot hole of the rotating sorting cylinder 11, the finished rice 16. The grains containing a relatively large amount of brown rice that do not reach the supply gutter 14 are received by the return shelf 23 and guided down from the upper rotation side of the rotary sorting tube 11 to the lower rotation side of the rotation sorting tube 11, and are guided through the rotation of the rotation sorting tube 11 once. The grains to be sorted are flown down and returned to the lower side of the rotation than the lower side of the rotation of the fluidized bed formed by the process, increasing the chance of the grains mixed in with a relatively large amount of brown rice to fit into the pot hole, increasing recovery efficiency. The grains to be sorted in the rotary sorting tube 11 are sorted while being raised, and the grains to be sorted in the rotary sorting tube 11 are sorted by flowing from the supply side to the discharge side one after another while repeating such an action. Grain is returned downstream in approximately proportion to the amount, and the upstream and downstream passages 2
4. The grains flowing down the downstream passage 25 are detected by one grain detection sensor 26. When the lower grain detection sensor 27 detects the flow of grains and the upper and lower grain detection sensors 26 and 27 both detect the grain flow, the output interface 30 is output from the comparison control section 29.
．． A reverse drive signal is output to the control motor 33 via the reverse drive circuit 31, the paddy supply control valve 34 is adjusted to the decreasing side, and the upper and lower grain detection sensors 26 and 27 both control the grain flow. When it is not detected, the comparison control section 29 outputs the output interface 30. A forward rotation drive signal is output to the control motor 33 via the forward rotation drive circuit 32, the paddy supply control valve 34 is adjusted to the increasing side, and (1) the grain detection sensor 26 does not detect grains; When the illegal grain detection sensor 27 detects grains, the comparison control unit 29 does not output a control signal, the control motor 33 does not rotate, and the paddy supply control valve 34 maintains the same state. Through related control, the amount of grains to be sorted to the rotary sorting cylinder 11 is properly adjusted through the paddy supply m-section valve 34, and the sorting accuracy can be improved. Since the two grain detection sensors 26 and 27 are provided on the upper side of the reduction shelf 23, they are covered by the finished rice gutter 16 and the reduction shelf 23, and even when the rotating sorting tube 11 is removed, Rotary sorting cylinder 11
This eliminates the drawbacks of conventional devices without interfering with or colliding with other devices.
