2 is provided.

13 is a drive roller that rotates the rotary sorting cylinder 12.

The rotating sorting cylinder has one axial end formed at a starting end side 15 and the other end formed at a terminal end side 14, with the terminal end side 14 being close to the supply hopper 2 and the starting end side 15 being located at a position distant from the supply hopper 2. do.

The rotary sorting cylinder 12 includes a mixed rice conveying device consisting of a mixed rice receiving gutter 16 and a conveyor 18 for conveying the mixed rice from the terminal end side 14 to the starting end side 15, and a brown rice conveying device consisting of a brown rice receiving gutter 17 and a conveyor 18. will be established.

The mixed rice receiving trough 16 and the brown rice receiving trough 17 are provided in parallel, and the mixed rice receiving trough 16 is provided closer to the rotation rising side.

On the starting end side 15 of the mixed rice receiving trough 16 is the rotating sorter 01.
A falling part 19 is formed which opens so as to be biased away from the scooping side of No. 2. A receiving tray 21 leading to the supply hopper 2 is provided below the terminal end side 14 of the zero-rotation sorting cylinder for discharging finished rice from the conveyor on the brown rice receiving trough 17 to the outside of the machine. 2
2 is a discharge gutter of the grain frying device 8, and is connected to the terminal side 1 of the mixed rice receiving gutter 16.
It is connected to 4.

B is a brown rice control valve installed at an intermediate position between the mixed rice receiving gutter 16 and the brown rice receiving gutter 17, and its shaft support 24 is lowered so as to be located approximately near one end of the conveyor B, and the mixed rice and brown rice are Separate.

(effect) Next, we will discuss the effect.

The unhulled rice supplied to the supply hopper 2 is passed through a pair of hulling rolls 3
The mixed rice consisting of brown rice a and unhulled rice flows into the first conveyor 6, and the immature grains flow into the second conveyor 7. Light rice husks are sucked into the suction blower 5 and blown out of the system.

The mixed rice that has flowed first into the conveyor 6 is fried by the grain frying device 8, and is supplied from its discharge gutter η to the terminal end side 14 of the mixed rice receiving gutter 16 of the - number of rotating sorting cylinders l, and then transferred to the conveyor. 18 and reaches the starting end side 15, and falls from the falling part 19 into the rotary sorting cylinder η.

In this case, the falling part 19 is opened so as to be biased away from the scooping side of the rotary sorting tube 12, so that the mixed rice is diffused in the circumferential direction inside the rotary sorting tube 12.
Improve the sorting effect.

Inside the rotary sorting tube, the rotation of the rotary sorting tube causes the brown rice a, which has a large specific gravity and is easy to slip, to sink to the lower layer, and the non-slip paddy rice floats to the surface and separates on top of the brown rice a, as shown in Figure 3. Therefore, the brown rice a that has sunk to the lower layer is relatively fit in the pot hole 11, and the unhulled rice that has floated to the upper layer is relatively small.
When the rotary sorting cylinder 4 is rotated clockwise as shown in Fig. 2,
The brown rice a that is deeply fitted in the pot hole 11 is mixed rice receiving trough 1.
6 and reaches the brown rice receiving trough 17, where it is taken out as finished rice by the conveyor, and a part of the unhulled rice that is shallowly fitted with the remaining brown rice a flows into the mixed rice receiving trough 16.

At this time, between the mixed rice receiving gutter 16 and the brown rice receiving gutter 17,
Since a lot of mixed rice will fall, adjust the brown rice control valve n to prevent unhulled rice from entering the conveyor chamber. It can be extracted as In addition, since the position of the shaft support 24 is low, when the brown rice control valve n is rotated, the brown rice control valve n
Since the upper end position can be adjusted both wide and narrow; ijgm and height at the same time, it is advantageous for adjustment when the amount of unhulled rice rises is small.

Thus, the remaining unhulled rice taken out to the terminal end side 14 is returned to the head via the saucer 21.

(Effects) As mentioned above, conventional hulling equipment separates the mixed rice obtained in the hulling section into brown rice and hulled rice, takes out the sorted brown rice as finished rice, and processes the first sorted unhulled rice for reprocessing. A device was provided to return the head to the head of the head.

However, the conventional device is expensive, generates a lot of vibration, and has a large volume. Grain damage was also significant.

However, the present invention has a rice hulling part l and countless pot holes 1 on the inner peripheral surface.
! The sorting section 9 is provided with a mono-barrel rotary sorting tube 12 that rotates on a horizontal axis, and the rotary sorting tube is formed on one side in the axial direction on the starting end side 15 and on the other side in the axial direction on the terminal end side 14. Inside the rotary sorting cylinder 12, there is a mixed rice receiving trough 16 which conveys the mixed rice from the hulling section 1 from the terminal end side 14 toward the starting end side 15 and supplies it into the rotary sorting cylinder 12 at the starting end side 15. established,
Further, a brown rice receiving channel 17 is provided in the rotary sorting tube in parallel with the mixed rice receiving channel 16, and the mixed rice receiving channel 16 and the brown rice receiving channel 17 are connected to the pot hole 1 formed on the inner peripheral surface. ! The mixed rice receiving gutter 16 and the brown rice receiving gutter 17 are formed with one side open so as to receive the mixed rice and brown rice scooped up by the machine, and the ends of the brown rice receiving gutter are open to the outside of the machine. This is because the structure of the hulling device is such that a brown rice Wffj valve n is provided in an intermediate position, with the shaft support 24 located near the conveyor of the brown rice receiving trough 17.

B. The rotary sorting cylinder is not a double cylinder, but a single cylinder, so the structure is simple.

The mixed rice receiving trough 16 inside the opening conveys the mixed rice from the hulling section l from the terminal end side 14 to the starting end side 15 and supplies it into the rotating sorting cylinder at the starting end side 15, and For rice and wheat, the gutter 16 is the pot hole 1 formed on the inner circumferential surface of the rotary sorting tube.
Since it receives the mixed rice scooped up in step 1, it functions as both a supply and circulation function.

C. The mixed rice that has been sorted in the rotary sorting tube and scooped up in the pot hole 11 is circulated in the rotary sorting tube 12 without being guided outside the machine, so there is little damage to the grains.

2. A lot of mixed rice falls between the mixed rice receiving gutter 16 and the brown rice receiving gutter 17, but if you adjust the position of the brown rice regulating valve n,
No unhulled rice will enter the inside of the conveyor, so if you constantly adjust it carefully, you can take out brown rice without unhulled rice as finished rice. In addition, since the position of the shaft support 24 is low, by rotating the brown rice control valve n, the upper end position of the brown rice control valve B can be adjusted both wide and narrow, as well as high and low. This is advantageous for section A.
