The width of front and rear is about 40 to 50 cm, and the front and rear walls 73 and 72 surrounding the front and rear of the air-selection chamber 68 have front and rear widths of about 60 cm.

[0019]

Next, the operation will be described. When the paddy rice is put into the supply hopper 30 and the opening / closing shutter of the supply hopper 30 is opened by an arbitrary method, the paddy rice is supplied to the up-down inclined rolls 33 and 34 to be hulled. The chaff is sucked in and discharged from the machine, the sorted mixed rice falls into the mixed rice receiving gutter 38 and is sent further by the conveyor 39, is supplied to the lower end of the mixed rice bucket elevator 5 and is fried, It is stored in the fixed storage tank 6. In addition, the second product that has fallen into the second gutter 41 is fried in the second thrower 43 and returned to the paddy gutter 44. At this time, the vertical tilt rolls 33, 3
4 is, for example, by rotating the rotation handle 63,
The upper sloping roll 33 is perspective-adjusted and adjusted to an optimum interval and hulled. In some cases, foreign matter such as a tool may be supplied. In this case, the abnormal handle 66 is pulled to widen the interval to prevent breakage.

When the opening / closing shutter of the fixed storage tank 6 is appropriately opened while looking at the inside through the window 60, the mixed rice is supplied from the fixed storage tank 6 to the distribution device 8 and the bottom plate 19 of the distribution device 8 vibrates. Move to split port 20, split port 2
It is divided by 0 and supplied to the sorting plates 9 in each stage. Sorting board 9
Oscillates left and right by a cam wheel 12 rotated by a motor 13, but a large number of wobbling projections that can be swung to the right in the figure are formed on the plate surface of the sorting plate 9, so brown rice with a high specific gravity In, the paddy rice with a low specific gravity moves to the left in reaction and the mixed rice that is not separated is distributed in the center. The brown rice collected in the brown rice discharging section 23 on the right side falls to the brown rice outlet 48, is transferred to the right by the uniaxial spiral 51, and is transferred to the impeller 5
It is jumped up by 3 and taken out by the finished rice thrower 4. In this case, the upper end discharge portion 55 of the finished rice slower 4 is formed in the bent flow path 56 as shown in FIG. 7, and when the grain accumulates in the bent flow path 56, the wind of the impeller 53 is not discharged and returns from the return air path 57. Dust does not scatter because it is returned.

The sorting state of the sorting plate 9 can be seen through the see-through window 17, but if the grain is too close to the brown rice discharge section 23 side, the switch 18 is turned off because the right and left inclination is not enough. Operate the first adjusting motor 1 of FIG.
4 is turned on, the screw rod 15 is rotated to raise the right side of the selection plate 9, and in the opposite case, the first adjustment motor 14 is reversed to lower the right side of the selection plate 9. Further, when a little rice is mixed in the brown rice extracted by the finished rice thrower 4, since the position of the first partition plate 21 is too close to the left, the second adjustment motor 26 is energized. Screw rod 2
7 is rotated to move the first partition plate 21 to the right.

In the above sorting, the mixed rice dropped from the mixed rice outlet 49 is moved to the left by the single-axis counter spiral 52, collected in the mixed rice receiving trough 38, and is fried by the mixed rice bucket elevator 5. Further, the paddy rice taken out from the paddy rice outlet 50 is collected in the return paddy trough 44, returned to the supply hopper 30 by the return thrower 54, and crushed again.

According to the present application, however, the hulling portion 1 has the feed hopper 30 at the uppermost portion, and the hulling chamber 67 having the vertically inclined rolls 33 and 34 at the lower part of the feed hopper 30, and the hulling chamber 67 of the hulling chamber 67. In the case where the wind selecting chambers 68 are formed in the lower part, respectively, the supply hopper 30, the hulling chamber 67, and the wind selecting chamber 68 are surrounded by a front wall 73 and a rear wall 72, and a substantially rectangular hulling portion 1 is formed. The hulling drive chamber 69 is provided between the hulling chamber 67 and the rear wall 72, the conduction chamber 71 is provided between the wind selecting chamber 68 and the rear wall 72, and the wind selecting chamber 68 is connected to the wind selecting chamber 68. The return device chamber 70 is formed between the front wall 73 and the swinging and sorting unit 2. The swinging and sorting unit 2 is provided with a plurality of sorting plates 9 for swinging to the left and right to flow and sort the grains forward and backward. Since it is a hulling device, a rubber roll is installed in the hulling drive chamber 69 formed between the hulling chamber 67 and the rear wall 72. A moving mechanism can be provided, a conduction chamber 71 can be provided between the wind selection chamber 68 and the rear wall 72, and a pulley or a belt can be provided between the wind selection chamber 68 and the front wall 73.
