The IB2 hulling section 1 consists of a paddy tank 9 and a hulling chamber 10, and a pair of hulling rolls 11 are installed in the hulling chamber 10. It is used to remove the paddy.

The wind selection section 2 uses the selection air sucked in from the intake port 13 opened on the upper wall of the fuselage by the suction machine 12 at the front, and the selection air blown from the air selection 114 provided at the rear to remove the undercover section 1. This is to perform m-selection of the ground rice from the rotary sorting section 3 and the brown rice from the rotary sorting section 3.

The wind sorting section 2 is equipped with a second conveyor 15, a mixed rice conveyor 16, a brown rice conveyor 17, and a paddy conveyor 18. , mixed rice thrower-19,
The brown rice thrower 20 and the paddy thrower 21 are connected to each other.

The rotary sorting section 3 is a substantially closed machine that sorts the mixed rice (a mixture of brown rice and paddy) that has been dehulled and wind-sorted by the wind sorting section 2 of the dehulling section 1 into brown rice and paddy. Sorting cylinder 5 inside wall 22
The sorting cylinder 5 is arranged horizontally, and the sorting cylinder 5 has a cylindrical shape, and has a large number of depressions a into which brown rice can be inserted. Support drive wheels 24 rotated by rotation shafts 23 are connected to each other, and the sorting cylinder 5 can be rotationally driven by the support drive wheels 24.

In addition, the mixed rice in the mixed rice tank 25 is transferred from the front to the rear (from the left to the right in Fig. 2) into the sorting cylinder 5 to prevent it from falling into the sorting cylinder 5 from the rear. A mixed rice transfer W127 having a mixed rice supply spiral conveyor 26 is installed in parallel with the sorting cylinder 5, and in parallel with this mixed rice transfer gutter 27, the brown rice scooped up by the many depressions a of the sorting cylinder 5 is transferred to a designated number. A mixed rice receiving trough 29 is constructed to receive the mixed rice containing a small amount of brown rice mixed into the paddy. A spiral conveyor 30 is mounted on a shaft, and a mixed rice discharge spiral conveyor 31 is mounted on a shaft inside the mixed rice receiving gutter 29.

A mixed rice supply port 6 for supplying mixed rice into the sorting cylinder 5 is connected to the transfer terminal end of the mixed rice transfer gutter 27. Supply port 6
A guide member 7 for guiding the mixed rice discharged from the sorting cylinder 5 to the inner circumferential surface of the rotating sorting cylinder 5 is continuously provided. This guide member 7
As shown in FIG. 3, the distal end thereof is formed into an arc shape in the direction of rotation of the sorting cylinder 5, and is made of a steel plate, an elastic body, or the like.

The brown rice receiving trough 28 is provided with a gate valve 28a that can be adjusted freely, and a brown rice conveyor 17 is provided at the front end side of the brown rice receiving trough 28.
A brown rice discharge port 32 communicating with the brown rice outlet 32 is arranged in stages. Also,
On the front end side of the mixed rice quantity l129, there is a mixed rice conveyor 1.
A mixed rice discharge port 33 communicating with 6 is provided.

Next, the operation of the above embodiment will be explained.

When the rotating parts of the sheathing section 1, wind selection section 2a3, and rotary sorting section 3 are rotationally driven by a prime mover (not shown), the shedding section 1
The mixed rice that has been unhulled and wind-selected by the wind sorting section 2 is transferred by the mixed rice conveyor 16 and thrown up into the mixed rice tank 25 by the mixed rice thrower 19. The mixed rice is supplied to the starting end of the transfer tii 27, is transferred by the mixed rice supply spiral conveyor 26, and is supplied from the mixed rice supply port 6 of the mixed rice transfer gutter 27 via the guide member 7 to the rear part of the separation cylinder 5.

The mixed rice supplied into the sorting cylinder 5 is in a circulating state inside the sorting cylinder 5 which rotates in the direction indicated by the arrow in FIG. However, the person fell over the gate valve 28a and into the brown rice receiving gutter 28,
Although the paddy is circulated, it is blocked by the gate valve 28a and flows down as it is, and the paddy and brown rice are separated. Then, a small amount of brown rice is mixed into the falling paddy, and the IC mixed rice falls into the mixed rice receiving trough 29.

1 = Brown rice that has fallen into the brown rice receiving gutter 28 is transferred by the brown rice take-out spiral conveyor 30 to the brown rice discharge port 32 of the brown rice receiving gutter 28.
After being air sorted from the air sorting section 2'c, the brown rice falls onto the brown rice conveyor 17 and is thrown up by the brown rice thrower 20 and taken out of the machine.

The mixed rice that has fallen into the mixed rice receiving trough 29 is transferred by the mixed rice discharge spiral conveyor 31, and is transferred from the mixed rice discharge port 33 to the mixed rice conveyor 16 and mixed rice thrower 19.
The rice is then thrown up into the mixed rice tank 25 and re-sorted.

On the other hand, the paddy remaining in the sorting cylinder 5 is transferred as it is and falls from the front end of the sorting cylinder 5 onto the paddy conveyor 18, and is also bounced up into the paddy tank 9 by the paddy thrower 21 and returned to the hulling section 1. You will be stripped of your clothes.

In this way, brown rice is sorted from the unhulled and wind-sorted mixed rice. According to the above embodiment, the mixed rice fed into the sorting cylinder 5 from the mixed rice supply port 6 is The mixed rice is fed gently onto the circumferential surface of the sorting cylinder 5 as it is guided by a guide member 7 whose tip end is shaped like an arc with a cross-section number in the rotating direction inside the sorting cylinder 5. The grain layer at the lower position of the grain layer 6 is approximately equalized with the grain layer circulating in the sorting cylinder 5, so that sorting can be performed satisfactorily.

FIGS. 4 and 5 show a second embodiment, in which a part of the mixed rice is circulated through a sorting cylinder 5 and sorted in a rotary sorting section 3. , the mixed rice supplied from the mixed rice supply port 6 and the mixed rice circulated within the sorting cylinder 5 are supplied to the inner peripheral surface of the sorting cylinder 5 via the guide member 34. There is C.

Like the guide member 7 of the first embodiment, the guide portion 4134 is formed into an arc shape with its front end facing in the rotational direction of the sorting cylinder 5, and is made of a steel plate, an elastic body, or the like. 35 is a downstream plate.

Therefore, the mixed rice supplied from the mixed rice supply port 6 and the mixed rice circulated within the sorting cylinder 5 are guided by the guide member 34 and are gently fed into the inner peripheral surface of the sorting cylinder 5, so that they can be sorted. The grains are fed at approximately the same speed as the grains circulating in the cylinder 5, and are smoothly scooped up by the sorting cylinder 5.

6 to 8 show the dimensions of the third embodiment, and in this embodiment, a plurality of guide vanes are provided on the side wall circumferential surface 36 of the supply side end of the sorting cylinder 5 on the side of the mixed rice supply port 6. 8 is provided and configured to guide the mixed rice flowing down from the mixed rice supply port 6 toward the discharge side of the sorting cylinder 5.

Therefore, the grains do not stagnate at the supply side end of the sorting cylinder 5 and are guided and transferred to the iJl outlet side by the guide vanes 8, so that all the mixed rice is sorted while being circulated through the sorting cylinder 5. This prevents paddy from being mixed into the brown rice as finished rice, especially at the position below the mixed rice supply port 6, and improves the sorting performance.

9 to 11 show a fourth embodiment. In this embodiment, the mixed rice supply port 6 is disposed at the end of the sorting cylinder 5 on the supply side, and the sorting cylinder The side wall circumferential surface 36 and inner circumferential surface of the supply side end of the body 5 are formed into a flat part 37 to direct (guide) the mixed rice flowing down from the mixed rice supply port 6 toward the discharge side of the sorting cylinder 5. It is composed of

Therefore, the grains do not stagnate at the supply side end of the sorting cylinder 5 and are guided and transferred to the C discharge side by the flat part 37, so that all the mixed rice is circulated through the sorting cylinder 5. This prevents paddy from being mixed into the brown rice as finished rice, especially at the position below the mixed rice supply port 6, and improves the sorting performance.

Note that in FIGS. 4 to 11, reference numerals J3 and the same reference numerals as in FIGS. 1 to 3 indicate similar components.

As is clear from the above description, according to the configuration of the present invention, grains can be fed while being guided by the guide member in the rotational direction of the sorting tube. For this reason, the moving directions of the grains supplied to the sorting cylinder are likely to coincide, and the relative speed is also reduced. Therefore, there is less bouncing of the supplied grains, and the grains are more easily applied to the sorting tube, so that sorting is carried out rationally and the sorting performance is improved.

In addition, if the supplied grains are guided by a downward guide member installed on the upper side in the axial direction of the sorting tube than the grain supply point, the supplied grains may not pile up at the supply point. few. Therefore, the layer thickness of grains tends to be uniform along the grain flow direction in the axial direction of the sorting tube, and the whole sorting tube can be used to perform rational sorting, improving sorting performance. It can be improved.

Note that this invention is not limited to the above-mentioned embodiments, and the invention can be implemented in modes other than the above-mentioned embodiments.
