Approximately the same action as that of raising the inner circumferential surface of the sorting cylinder (6) in the sorting cylinder (6) is performed. To)
The unscooped paddy and a small amount of unscooped rice are blocked by the F side of the partition plate (7). While the waste is accumulated, it flows in that part and passes through the secondary sorting section (
C2) promotes the sorting action at the end of step C2), and as the accumulated amount increases, the washed-out rice comes out of the notch fb), flows into the beginning of the primary sorting section (OL), and falls from the primary supply port ue. and is subjected to the sorting action in the above-mentioned primary sorting section (0) and is re-sorted.

The brown rice that comes out from the secondary receiving channel 12 through the brown rice channel (19) flows into the receiving funnel of the rice sorter (nl) and passes through the cylindrical body 011 covered with an appropriate mesh or perforated iron plate. The waste rice that has been sorted by the motion is taken out of the machine from the discharge gutter 02, and the stopper that has not leaked through the mesh or perforated iron plate flows into the wind selection section fB) from the flow path [with] and is sucked into the suction air. The fine dust is removed and stored in a designated container.

In addition, as far as shown in Fig. 5, the partition plate (7) is used for the primary sorting part (Co side and above it) of the secondary catch gutter UZ, and the catch plate □
Although the back side of □□ is not partitioned, if the entire surface including these parts is partitioned, there will be no complement of unsorted grains from the primary sorting section (C1).

As shown in Figure 8, the diameter of the sorting cylinder (6) in the VC primary sorting section (C1) is increased to create a step at the boundary with the secondary sorting section 5 (C2), that is, at the same level as the partition plate (7). If this step is installed, this step will prevent the scraped rice falling from the primary feed port [161] from flowing back into the secondary sorting section (C2). The next sorting section (transfer to the beginning of CO is also carried out smoothly, and the huge primary sorting section (
The hood ability in C1) will also be further improved.

As described above, the present invention includes a sorting cylinder having a large number of depressions formed in its inner circumferential surface, which is rotatably installed horizontally, and a receiving gutter for taking out the sorted parts scooped up by the depressions in the sorting cylinder. In the cylindrical rotary sorting device, a partition plate is provided in the middle part of the sorting cylinder to partition the inside of the cylinder to form two sorting sections, and the rotation of the sorting cylinder at the corner of the partition plate is A notch is formed on the upper side in the moving direction to allow the unsorted grains to flow from one sorting section to the other, thereby making it possible to carry out primary and secondary sorting with one sorting cylinder, while also allowing internal separation. The receiving trough and the transfer trough are integrated and strong, and unsorted grains do not scatter or flow from one sorting section to the other, preventing sorting from being obstructed, and even at the final stage of sorting. Appropriately restrict the flow migration of unsorted grains1.
By ensuring the thickness of the layer, the sorting action can be carried out effectively.
