A screw conveyor 49 is mounted on the shredding transfer gutter 43, and a screw conveyor 50 is mounted on the paddy transfer gutter 47.

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

The rice grains supplied to the supply hopper 14 of the removing device 9 fall into the removing chamber 11 from the supply port 13 and are removed by the removing roll 12. The collected dust reaches the grain transfer gutter 19, is transferred by the screw conveyor 21, and is lifted to the hopper 26 of the rotary grain sorting device 10 by the grain lifting machine 23. The grains supplied to the hopper 26 are supplied to the starting end (the left end in FIG. 1) of the grain transfer device 27, and then to the sorting cylinder 1 from the supply port 32 at the terminal end (the right end in FIG. 1). It is supplied to one end in the axial direction (the right end in FIG. 1).

The grains supplied to one end in the axial direction of the sorting tube 1 are quickly transferred toward the other end in the axial direction of the sorting tube 1 by the flow regulator 28, and the grains are rectified to have a uniform layer thickness while passing through the sorting tube. 1, the grains (brown rice) with a higher specific gravity sink down, fit into the pot hole 1a, are scooped up, go over the grain guide 35 of the grain transfer device 2, and are shed from the grain receptacle 4. The grains fall into the transfer gutter 33, are transferred by the screw conveyor 34, and are removed from the flow path 42 to the shedding transfer gutter 43.
The grains fall into the interior of the machine, are then transferred by a screw conveyor 49, are fried by a grain lifting machine 44, and are taken out of the machine. Next, when the remaining grains come to the axially intermediate part of the sorting tube 1, the grains sorted by the rotation of the sorting tube 1 are taken out from the grain receiving port 4 to the grain transfer device 2, and at the same time, the mixed grains are from the mixed grain socket 5 to the intermediate shelf 3 beyond the mixed grain guide 36
, flows down this intermediate shelf 3 and is returned to the rear of the rotation of the sorting tube 1 . The reduced mixed grains are sorted again by the rotation of the sorting cylinder 1. moreover,
When the residual shedding reaches the other end side in the axial direction of the sorting tube 1, the shedding sorted by the rotation of the sorting tube 1 falls into the shedding transfer device 2 from the shedding receptacle 4 and is sorted at the same time. The mixed grains are taken out from the mixed grain receptacle 40 to the mixed grain transfer device 29. The mixed grains that have fallen into the mixed grain transfer gutter 38 of the mixed grain transfer device 29 are transferred from the screw conveyor 39 and fall from the flow path 45 into the grain transfer gutter 19, and are transferred to the screw together with the grains from the removing device 9. The grains are transferred by a conveyor 21, fried by a grain lifting machine 23, and supplied to a hopper 26 of the rotary grain sorting device 10. Then, the grains from which the grains are removed and are reduced to almost only unshredded grains are transferred to the other end in the axial direction while being reduced by the grain reducing body 41 toward the rear of the rotation of the sorting cylinder 1, and are passed from that end through the flow path 46. The paddy falls into the paddy transfer gutter 47 and is transferred by the screw conveyor 50.
The grains are fried by the grain lifting machine 48 and supplied to the supply hopper 14, and then supplied again to the dechamber 11 and de-rolled by the de-roller 12.

In this way, the separated grains are taken out, but as the amount of mixed grains that fall into the intermediate shelf 3 and return to the rear of the rotation of the sorting cylinder 1 increases, the rate of unshelved grains mixed into the mixed grains increases. As a result, the unshelved grains are mixed with the threshed grains, and the finishing accuracy of the shredded grains deteriorates. Therefore, the grain removal guide 35 of the grain removal transfer device 2 and the mixed grain guide 36 of the intermediate shelf 3 are connected to each other.
Since they are interlocked and connected by 7, the threshing guide 3
In conjunction with the change in the inclination angle of 5, the mixed grain guide 36
The inclination angle will be changed in the same direction,
The mixed grain receptacle 5 of the intermediate shelf 3 is always maintained at a constant opening area. Therefore, the amount of mixed grains falling into the intermediate shelf 3 is always maintained at a constant amount, and it is possible to prevent unshipped grains from being mixed into the shredded grains.

In the above embodiment, the mixed grain guide 36 is provided on the slope and end of the intermediate shelf 3, and this mixed grain guide 36 is interlocked with the finishing grain guide 35 of the grain shedding transfer device 2 via the connection 37. However, the intermediate shelf 3 is integrally provided rotatably, and the intermediate shelf 3 itself is connected to the connecting 3.
Needless to say, it may be configured to be interlocked with the grain removal guide 35 via 7.

6 to 12 show an embodiment of the second invention, and in this embodiment, as shown in FIG. 7, the intermediate shelf 3 is interlocked with the output shaft 52 of a drive device 51 such as a motor. It is rotatably supported via a connected drive shaft 53. The drive device 51 is the fuselage 8
The drive shaft 53 is attached to a support member 5 superimposed on the grain transfer gutter 30 of the grain transfer device 27.
4, it is rotatably supported. In the intermediate part of the grain flow direction of the intermediate shelf 3, a seventh
As shown in FIG. 9, a sensing device 7 for detecting grains flowing down on the intermediate shelf 3 is provided by a pair of grain sensors S-1 and S-2, and this grain sensor S- The operating device 6 is configured to adjust the inclination angle of the intermediate shelf 3 by rotating the drive device 51 in the forward and reverse directions based on the outputs generated by the grains detected by the grains detected by the grains 1 and S-2. Although not shown, the intermediate shelf 3 has a sloughing guide 35 similar to the first invention.
It is configured in conjunction with.

FIG. 11 shows an operating circuit diagram of the drive device 51 of the intermediate shelf 3, where R ₁ is the grain sensor S-1.
The relay coil R ₂ is activated by the grain sensor S-2, and the relay coils R ₁ and R ₂ are connected to the grain sensor S-2 as shown in FIG. This is turned on and off in relation to the detection and non-detection of grains No. 1 and S-2. r ₁ is the relay a contact of relay coil R ₁ ,
r ₁ is the relay b contact of relay coil R ₁ , r ₂ is the relay a contact of relay coil R ₂ , ₂ is the relay coil
This is the relay b contact of _R2 .

According to the above configuration, during sorting work, when the amount of grains flowing on the intermediate shelf 3 is appropriate, one of the grain sensors S-1 and S-2 is not detecting grains, only the other grain sensor S-2 is detecting grains, and the drive device 51 is in a non-operating state.

Now, if the amount of grains flowing down on the intermediate shelf 3 is too large, the grain sensors S-1 and S-2 simultaneously detect the grains. When the grain sensor S-1 detects grains, the relay coil _R1 is energized, and its relay A contact R1 is closed, and the relay B contact ₁ is closed _.
opens, the drive device 51 rotates forward, and the intermediate shelf 3 operates the mixed grain receptacle 5 in the closing direction. And middle shelf 3
The amount of mixed grains falling into the container is reduced.

In addition, if the amount of grains flowing down on the intermediate shelf 3 is too small, the grain sensors S-1 and S-2
does not detect grains at the same time. Grain sensor S-2
does not detect any grains, relay coil R ₂
is energized, its relay a contact r ₂ closes, and its relay b contact ₂ opens, causing the drive device 51 to rotate in reverse and the intermediate shelf 3 to operate the mixed grain receptacle 5 in the opening direction. Then, the amount of mixed grains falling into the intermediate shelf 3 increases. Therefore, the sorting of shedding particles is effectively carried out.

As is clear from the above explanation, according to the configuration of the first invention, the adjustment of the granulation socket of the granulation transfer device and the mixed granulation socket of the intermediate granulation is linked, so that the granulation reception port can be adjusted. Then, the mixed grain receptacle is also adjusted, the proper state of both is maintained, the sorting accuracy is improved, and the adjustment is easy.

According to the configuration of the second invention, when the amount of grains to be sorted in the sorting cylinder increases or decreases from a predetermined amount, the threshing socket and the mixed grain socket of the intermediate shelf move up and down accordingly. This improves sorting accuracy by preventing paddy from falling into the threshing socket.
In addition, mixed grains with a high ratio of brown rice flow into the mixed rice receiving port of the intermediate shelf and are returned to the sorting tube, improving the ratio of brown rice that enters the pot hole of the sorting tube, thereby improving the sorting ability. It is something that can be done.

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.
