The structure is such that an opening 8 located on the cylinder axis side is left and an end wall 7 of an appropriate height facing inward of the cylinder is formed to prevent the grains in the rotary sorting cylinder 4 from flowing out from the end. The structure is such that a thick grain layer is formed.

In addition, receiving troughs 2 and 3 are installed between the front and rear walls of the machine body, passing through the rotary sorting cylinder 4, and spirals 11 and 12 are each rotatably installed inside the receiving troughs 2 and 3. ing. One of the receiving plates 5 in this upper receiving gutter 2 is made rotatable in the middle by a pivot part 13,
The receiving plate 5 is configured to be able to rotate up and down and freely adjust its angle.
The rotary sorting tube 4 is rotated upward as shown by the solid line.
The rotary sorting tube 4 approaches the inner circumferential surface of the rotary sorting tube 4, and its tip reaches the end wall 7 when viewed from the axial direction of the rotary sorting tube 4, as shown by the phantom line.
The end wall 7 rotates toward the inner circumferential side of the cylinder when viewed from the direction of the cylinder axis.
It is configured so that it can be changed to a folded state located within the opening 8 on the inner circumferential side. Also, the other receiving plate 6
is provided with a pivot 14 at its base so that it can be rotated largely toward the inner and outer circumferences, and similarly to the receiving plate 5 described above, it can be changed into an extended state and a folded state. The receiving gutter 3 is located slightly lower than the receiving gutter 2, and has a receiving plate 15 protruding toward the lower side of the receiving plate 5, but this receiving plate 15 is located outward from the diameter of the opening 8. When it is in the extended form, it is constructed so that it can be rotated and folded like the receiving plate 5. 16 is a guide plate that closes the receiving trough 3 at appropriate intervals on the grain supply side.

The rotary sorting tube 4 is covered by a case 35, and the part of the mounting frame 18 facing the rear end side (the right side in FIG. 2) of the rotary sorting tube 4 in the case 35 is
It has a configuration that can be opened and closed rearward, and the rear end portions of the receiving troughs 2, 3 and the spirals 2, 3 are supported on the front side of this mounting frame 18, and this mounting frame 18 can be detachably attached to the rear of the case 35. It is provided.

An opening 8 is formed on the inner peripheral side of the end wall 7 at the rear end of the rotary sorting tube 4, and the receiving troughs 2, 3, receiving plates 5, 6, spirals 11, 12, etc. are passed through the opening 8. The rotary sorting cylinder 4 can be removed by pulling it backward along the longitudinal direction, and the mounting portion of the mounting frame 18 has an opening through which the receiving troughs 2, 3, etc. attached to the mounting frame 18 can pass. A section 36 is provided. The front ends of the receiving troughs 2 and 3 can be placed on a bracket 38 on the front wall of the case 35, and the helices 11 and 12 are configured to fit together so that their front ends can be rotated in conjunction with a coupling ring 37. . Reference numeral 39 denotes an upper cover that closes the upper part of the case 35, and is configured to be openable and closable, and the rotary sorting cylinder 4 can be removed upwardly from the opening in the upper part.

The rice removed from the hulling section (not shown) is conveyed rearward by the helical 12 of the receiving trough 3, and is supplied to the rear sorting start end of the rotary sorting tube 4. Then, while the rice in the rotary sorting tube 4 flows sequentially from the sorting start end to the end end, it fits into the recesses 1, 1, and is scooped up, and the small brown rice is scooped up high and placed in the upper part. The receiving plate parts 5, 6 and the receiving gutter 2 are dropped and sorted, and
Large paddy and some brown rice are scooped up low,
It falls into the receiving plate 15 and the receiving gutter 3 and is sorted. The grains, mainly consisting of paddy, which have been sorted in this way and have reached the sorting end of the rotary sorting tube 4 are returned to the hulling section (not shown) and are hulled again. Furthermore, the brown rice sorted into the receiving trough 2 is transferred by the helical 11 and taken out from the terminal side, and the mixed rice in the receiving trough 3 is transferred to the terminal side by the helical 12. , and is again supplied to the sorting start end side of the rotary sorting cylinder 4, and the sorting is repeated.

When cleaning the rotary sorting cylinder 4, etc., remove the fixing device of the mounting frame 18 on the rear end side, and remove the support plate 5, 6.
This can be achieved by folding the support plates 5 and 6 toward the inner circumference of the rotary sorting tube 4, reducing the tips of the receiving plates 5 and 6 to positions corresponding to the openings 8 of the rotary sorting tube 4, and pulling out the mounting frame 18 rearward. The integrated receiving troughs 2, 3, receiving plates 5, 6, spirals 11, 12, etc. can be taken out together from the openings 8, 36, and the upper cover 39 is removed and the rotating rolls 9, 9... are removed. The placed rotary sorting cylinder 4 can be removed from the upper opening of the case 35.

At this time, the receiving plates 5 and 6 or the receiving plate 15 in the receiving troughs 2 and 3 get in the way, so if these are folded and rotated inward around the pivot parts, the rotary sorting cylinder 4
It is located in the opening 8 on the center side of the end wall 7, and can be easily attached and detached without the end wall 7 colliding with the receiving plates 5, 6 or the receiving plate 15.

Since the present invention is configured as described above, it has the following technical effects. That is, by the rotation of the rotary sorting tube 4, the grains supplied inside are sorted by specific gravity, and small grains with a large specific gravity sink down and fit into the recesses 1, 1... and are scooped upward. It falls into the receiving gutter 2 and is sorted, and this receiving gutter 2
At the upper end, a receiving plate 5 or 6 is extended toward the outer periphery of the rotary sorting tube 4 to receive the sorted grains as efficiently as possible, but it is also possible to receive the sorted grains as efficiently as possible. When cleaning or repairing the inside of the receiving gutter 2, the receiving plate 5 or 6 is rotated inward to reduce the size of the rotating sorting tube 4.
The receiving gutter 2 and the receiving plate 5 are reduced in size to the area corresponding to the opening 8 in the center of the end wall 7 formed at the end of the rotary sorting tube 4 while remaining in the case 35.
By pulling out the receiving plate 6 in the longitudinal direction, which is the axial direction of the rotary sorting tube 4, from the front side toward the rear side where the end wall 7 is, the rotary sorting tube 4 can be removed while being supported on the machine body. The gutter 2 and the receiving plate 3 can be removed from the fuselage, allowing for easy assembly and disassembly work.
