Therefore, when paddy is fed to Hoso: -t+4+ during operation, the grains that have been desexed by the huller (d2) are removed by the wind sorter (d2).
The mixed rice that has been sorted in the mixed rice conveyor (4) is thrown up into the supply tank from the mixed rice thrower (t15) K, and is sent to one end of the sorting tube (A) from the bottom of the tank. The mixed rice fed inward to the side (A) is in contact with the inner circumferential surface of the sorting tube (A) rotating in the direction of the arrow (toward), and the brown rice fits into the recess (1) and is lifted upwards. However, the paddy cannot fit into the recess (1) and slides down, and the brown rice that is lifted north falls out of the recess (1) above and is transferred to the right feeding part (C) of the spiral conveyor (C) in the receiving trough (B). The person falls onto the brown rice conveyor (6) from the gutter C34) through the falling plate 0, and is conveyed to the end side as shown by the arrow (G).
(It is jumped up and taken out by 171.

When the mixed rice of brown rice and paddy, which cannot fit into the concave part (1) of the sorting tube TA) and is transferred in the direction of the arrow (force), passes the part (+':I), most of the remaining brown rice The paddy is fully inserted into the large concave part (2), and -+xh of the paddy is caught in the part of the large concave part (2) that does not contain brown rice. 0), the person falls into the right feeding part (29), is carried in the direction of the arrow (force) by the right feeding part (29), and is transported to the gutter (
The person fell onto the mixed rice conveyor (4) from the branch)) and jumped directly into the supply tank by the mixed rice thrower L151'.
If you are kicked out, you will be re-sorted.

In addition, the paddy that is carried out in the direction of the arrow (P→) without getting caught in the recess (2) of the sorting tube (A) is transferred from the gutter to the single-blade conveyor (5) and by four people to the paddy thrower. (16)
It is then lifted up into the hopper (141) and ejected again.

In that case, inside the sorting tube (A), the four parts near the part (B) (the part of brown rice falling from +l into the receiving gutter (B) are fed rightward by one direction of the partition guide plate (E). The mixed rice part is guided to the side and falls, and the part of the mixed rice that falls into the receiving gutter (B) from the large recess (2) near the part (B) is guided to the left side by the other side of the partition guide plate (E). The person is guided to the feeding part (■) side and falls into a state where the person falls...by rotating the screw rod (32) and screwing the screw rod (three points and female threaded body C31) together, the partition guide plate is removed. (E) Separate the partition plate (
If you move it back and forth in the direction of the axis of the spiral conveyor (C) as shown by the arrow (nu) above - in 2), you can adjust the boundary between brown rice and mixed rice and perform partition guidance with high precision. .

In this way, when the main sprouting occurs, a large number of recesses (1) large enough to fit brown rice are formed on the inner peripheral surface of the cylindrical rotating and sorting tube (A) near one end, and the inner peripheral surface of the other end A large number of large concave portions (2) slightly smaller than the concave portions (2) are formed in the receiving trough (B) for receiving brown rice, etc., which is fixed inside the rotary sorting tube (A). (Ill and the surface (1) of the large concave part (2)
A spiral conveyor (C) whose feeding direction is opposite in the portion corresponding to 11!1 is mounted on an axis, and a partition guide plate (E) is moved in the axial direction above the boundary of the spiral conveyor (C) whose feeding direction is different. Since the sorting tube (A) and the spiral conveyor (rC) are connected to the huller (D) K, the concave part (+) of the sorting tube (A) ensures that only brown rice is harvested. In addition to being able to separate the mixed rice and paddy using the large concave portion (1), the separated brown rice and mixed rice are carried out in opposite directions by the inner spiral conveyor (C) and taken out to Fuko. Sorting tube (A)
The paddy can be discharged from one side and circulated well between the huller (D) and the paddy to be sorted with high precision.Moreover, the inner circumferential surface of the sorting cylinder (A) allows for the sorting. By adjusting the partition guide plate (E), brown rice and mixed rice can be guided to the spiral conveyor (c) through the partition 9, and the parts with these functions are grouped together inside the sorting cylinder (A). It can be configured as follows, and the whole can be made small.
It has the advantage of being suitable for implementation.
