A spiral conveyor 3' installed at the center of the lower part of the gutter b is installed so as to be able to rotate coaxially with the rotating shaft 30, and the cover 22
The lower opening of the feed gutter 31, which is attached to one end and whose upper part communicates with the terminal end of the receiving gutter B, is connected to the downward rotating sorting tube a.
One end side is installed so as to extend inward, and the other end side D of the lower rotary sorting tube a, which is on the side of the hulling section D, is connected to the mixed rice conveyor 8 via the flow plate 32. The lower part of the gutter 33 installed below the terminal end side of the receiving gutter b in the vicinity thereof is configured to communicate with the upper part of the flow plate 34 above the brown rice conveyor 9.

Therefore, one end of the rotary grain sorter C becomes the supply side and the other end becomes the discharge side.

Adjustment plates 4, 4 extending obliquely so as to approach the inner circumferential surfaces of the respective sorting cylinders A, a are installed at the upper part of one side of the receiving troughs B, b for the spiral conveyors 3, 3'.
The adjustment plates 4, 4 are installed in such a way that they can be rotated around the lower shafts 35, 35 to change the inclination. The bases of the adjusting bodies 5, 5' are fitted and fixed to the ends of the protruding shafts 35, 35, and the knobs 37 are fitted with springs 36, 36 interposed at the ends of the adjusting bodies 5, 5'. , 37 are installed so as to be able to engage with the arcuate chrysanthemum seats 38, 38 fixed to the case 22, respectively.
is installed on the outside of the case 22 on the supply tank 26 side which is opposite to the hulling section D, and the lower adjustment body 5' is installed on the outside of the case 22 on the hulling section D side.

On the outside of the case 22 on the side opposite to the hulling section D of the rotary grain sorter C, there are the two rotating shafts 2.
5 and 30 are extended with their ends up and down, and are installed so that transmission can be transmitted from a transmission shaft 39 protruding rearward of the gear case 6 to both rotating shafts 25 and 30 via a transmission part G of a group of belt pulleys. However, the transmission part G is constructed by covering it with a safety cover (not shown).

Therefore, transmission can be transmitted to each part of the huller F from the transmission part H arranged on the side of the wind sorting part E, and the rotary grain sorter C can be transmitted from the transmission part H to each part of the huller F through the gear case 6. can be driven.

During work, when paddy is fed to the hopper 16,
The hulled rice removed by the hulling section D is wind sorted in the wind sorting section E and falls into the mixed rice conveyor 8, and is also jumped up into the supply tank 26 by the mixed rice thrower 20, and is sent upward from the lower opening of the tank 26. The mixed rice fed inward at one end of the rotating sorting tube A is in contact with the inner peripheral surface of the sorting tube A rotating in the direction of the arrow H, and the brown rice is fitted into the recess 1 and lifted upward. However, the paddy cannot fit into the recess 1 and slides down the inner peripheral surface, and the brown rice that is lifted upward falls from the recess 1 and falls into the spiral conveyor 3 from the receiving gutter B as shown by the arrow. The rice sent to the other end of the upper rotary sorting tube A as indicated by the arrow T is discharged as is, returned to the hopper 16 through the paddy trough 27, and then taken out again.

On the other hand, brown rice, etc., which is sent to one end side as shown by the arrow H by the spiral conveyor 3 in the receiving gutter B, falls into the feeding gutter 31 and is transferred from the lower opening to the one end side C of the downward rotating sorting tube A. The brown rice mixed with a small amount of paddy is sorted in the same way as by the sorting tube A by the downward rotating sorting tube a that rotates as shown by the arrow R, and the brown rice is sorted from the receiving gutter b as shown by the arrow N. The brown rice that falls into the spiral conveyor 3' and is sent by the spiral conveyor 3' as shown by the arrow 3' is sent to the gutter 33,
The sorted rice passes through the falling plate 34, is sorted by the sorting wind, falls into the brown rice conveyor 9, is thrown up by the brown rice thrower 21, is taken out of the machine, and is sent inside the downward rotating sorting tube a as shown by the arrow O. The unprocessed brown rice and paddy drop from the other end D through the falling plate 32 into the mixed rice conveyor 8, and are again thrown up into the supply tank 26 by the mixed rice thrower 20 to be sorted.

In that case, when both adjusting bodies 5, 5' are rotated along the chrysanthemum seats 38, 38 while engaging the knobs 37, the adjusting plates 4, 4 are rotated around the shafts 35, 35, and the inclination is changed. As a result, it is possible to adjust the state in which the brown rice drops from the recess 1 and falls onto the receiving channels B and b, thereby making it possible to perform sorting adjustment.

As described above, the present invention provides receiving troughs B and b for receiving brown rice.
A rotary grain sorting machine C is constructed by arranging rotary sorting cylinders A and a above and below, each having a large number of recesses 1 large enough to fit brown rice on the inner peripheral surface. In the sorting machine C connected in communication with the husking machine F, one end of the rotary sorting cylinder A, a is located on the opposite side of the hulling machine F, and the other end B and d are placed on the side of the hulling machine F. Then, the mixed rice from the huller F is supplied to one end (a) of the upper rotary sorting tube A, and the rice is returned to the hulling section D of the huller F from the other end (b). Since the rice in the receiving trough B is supplied to one end side C of the rotating sorting tube A in the lower part for sorting, the mixed rice from the hulling machine F is transferred to the upper rotating sorting tube A in the opposite direction to the hulling machine F. The paddy that has been sorted by this sorting is taken out to the huller F side and can be returned to the huller D in a suitable manner. Pipe B of tube A
The rice received inside is carefully selected in the lower rotary sorting tube a, and only brown rice is taken out.Moreover, it is supplied to the opposite side of the lower rotary sorting tube A from the huller F, where it is carefully selected. The brown rice and paddy that are not sorted in the rotary sorting cylinder a can be easily reduced and re-sorted, and has the advantage that it can be carried out suitably with a simple structure.
