The rice grains are sucked into the dust machine 13 and transferred to the dust machine 16.
im 19 and is transferred by the screw conveyor 21 and lifted to the hopper 26 of the rotary grain sorting device 10 by the fried grain 1123. Supplied to this hopper 26! , :
The grains are supplied to the starting end (left end in FIG. 1) of the grain transfer field 27, and are fed to the supply port 32 at the terminal end (right end in FIG. 1).
From there, it is supplied to one end in the axial direction of the sorting tube 1 (the right end in FIG. 1).

The grains supplied to one end in the axial direction of the sorting tube 1 are quickly transferred to the other end in the axial direction of the sorting tube 1 by the fluid regulating 28 in the direction 8- (), and the grain thickness is evenly rectified. As the sorting cylinder 1 rotates, unhusked grains (brown rice) with a higher specific gravity among the grains sink, fit into the pot hole 18, and are scooped up (21). The dose powder falls into the dose transfer gutter 33 from the mouth 4, is transferred by the screw conveyor 34, falls from the flow path 42 into the deweighed particle transfer channel 43, and is then transferred to the screw conveyor 49. The grains are fried by the grain lifting machine 44 and taken out of the machine.Next, when the remaining grains reach the axially intermediate part of the sorting cylinder 1, the l+2 grains sorted by the rotation of the sorting cylinder 1 are removed. At the same time that the grains are taken out to the IB2B2 grain receiving port 4112 and the culm transfer device 2, the mixed grains fall over the mixed grain guide 36 from the mixed grain receiving port 5 to the intermediate shelf 3, and are separated from the intermediate shelf 4. The mixed grains flow down to the rear of the rotation of the sorting tube 1.The reduced mixed grains are sorted again by the rotation of the sorting tube 1.Furthermore, the remaining grains are transferred to the other end of the sorting tube 1 in the axial direction. At the same time, the descaled grains sorted by the rotation of the sorting cylinder 1 fall from the deweighed grain receptacle 4 to the descaled grain transfer device 2, and at the same time, the sorted mixed grains are mixed from the mixed grain receptacle 40. The mixed grains are taken out to the grain transfer device 29. The mixed grains that have fallen into the mixed grain transfer tiffl 38 of the mixed grain transport device 29 are transported by the screw conveyor 39 and flow down the flow path 45.
The grains fall into the grain transfer gutter 19 from the dosing device 9, are transferred to the screw conveyor 21 together with the grains from the dosing device 9, are fried by the grain lifting machine 23, and are supplied to the hopper 26 of the rotary grain sorting device 10. be done. Then, the deculminated grains are taken out and the grains, which are reduced to almost only the final deculminated grains, are transferred to the axially opposite end side while being moved by 19 parts toward the rear of the rotation of the sorting cylinder 1 by the paddy septane body 41. From the section to the paddy transfer gutter 47 via the flow path 46
It is transported by the scrico conveyor 50 and lifted [
The grain is fried by 1148 and supplied to the supply hopper 14,
It is again supplied to the dosing chamber 11 and deweighed by the deweighing roll 12.

The dose grains sorted in this way are taken out, but when the amount of mixed grains that fall onto the intermediate shelf 3 and return to the rear of the rotation of the sorting tube 1 increases, some of the unremoved grains are added to the mixed grains. As a result, the un-dehulled grains are mixed into the de-atomized grains, and the finishing accuracy of the de-culm grains deteriorates. Therefore, the dosed grain guide 35 of the bowl 1 powder transfer device 2 and the mixed grain guide 36 of the intermediate shelf 3
Since these are interlocked and connected by the connection 37, the inclination angle of the mixed grain guide 36 is changed in the same direction in conjunction with the change in the inclination angle of the dosage grain guide 35.
The mixed grain socket 5 is always maintained at a constant opening area. Therefore, the amount of mixed grains falling on the intermediate shelf 3 is always maintained at a constant amount, and it is possible to prevent un-de-culminated grains from being mixed in with de-culm grains.

In the above-mentioned embodiment, the mixed grain guide 36 is provided at the slope and end of the intermediate shelf 3, and the mixed grain guide 36 is connected to the connecting 3.
The internal structure of the qt It goes without saying that it may be constructed in conjunction with the grain guide body 35.

The drive device 51 is attached to the machine body 8, and the drive shaft 53 is rotatably supported by a support member 54 superimposed on the grain transfer gutter 30 of the grain transfer device 27. As shown in FIGS. 7 and 9, a pair of grain sensors S are provided at the intermediate portion of the intermediate shelf 3 in the direction of grain flow, as shown in FIGS. -1 and S-2 c) are installed, and the grain lensers S-1 and S-2 are
The inclination angle of the intermediate shelf 3 is adjusted by rotating the driving device 51 in the forward and reverse directions according to the output generated by the -2 detecting grains. Although not shown, the intermediate shelf 3
is configured to be interlocked with the pill guide 35 as in the first invention.

FIG. 11 shows an operating circuit diagram of the driving device 51 of the intermediate shelf 3, where R1 is a relay coil operated by the grain sensor S-1, R2 is a relay coil operated by the grain sensor S-2, This relay coil R1 and R
As shown in FIG. 12, 2 is a sensor that is turned on and off in relation to grain detection and non-detection of grain sensors S-1 and S-2. rl is the relay a contact of relay coil R1, Yl
is a relay b contact of relay coil R1, R2 is a relay a contact of relay coil R2, and 〒2 is a relay b contact of relay coil 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.

If there are too many grains flowing over the intermediate shelf 3,
Grain sensors-8-1 and S-2 simultaneously detect grains. When the grain sensor S-1 detects grains, the relay coil R1 is excited, and the relay A contact r1 closes and the relay B contact 〒1 opens, causing the drive device 51 to rotate forward and the intermediate shelf 3 to receive the mixed grains. 5 in the closing direction. Then, the number of mixed grains falling onto the intermediate shelf 3 is reduced.

Moreover, when the amount of grains flowing over the intermediate shelf 3 is too small, the grains 111I Renly-8-1 and S-2 do not detect the grains at the same time. When the grain sensor S-2 detects grains, the relay coil R2 is energized, the relay A contact R2 closes, and the relay H contact Y2 is activated, causing the drive device 51 to rotate in the reverse direction and the intermediate shelf 3 to rotate. Mixed grain socket 5
operates in the opening direction. Then, the number of mixed grains falling onto the intermediate shelf 3 increases. Therefore, the purchase (of 7 grains) is effectively carried out.

Figures 13 to 14 show examples of Haku,
In this embodiment, the hopper 26 of the rotary grain sorter 10
A control valve 56 that can freely open and close the supply port 55 is provided at the supply port 55.
The opening of the control valve 56 is adjusted by a driving device such as a motor or the like. and,
A grain sensor S-3 is installed at the bottom of the intermediate shelf 3 to detect the layer thickness of grains in the sorting tube 1.
-3 detects grains and generates an output to operate the drive device 57 and adjust the opening degree of the control valve 56.

According to the above configuration, during the sorting operation, when the grains circulating in the sorting tube 1 are proper claws, the grain sensor S-3 does not detect the grains, and the drive device 57 is in a state of not operating. It is.

If the amount of grains circulating in the sorting tube 1 is too large, the grain sensor S-3 detects the grains.

When the grain sensor S-3 detects grains, a timer (indicated by "Z" in the figure) causes the control valve 56 to be closed at a certain level.
57 is activated and reduces the grain supply. Therefore, the amount of grains supplied to the sorting n1 is automatically controlled, and it is possible to prevent rice grains from being mixed into the finished flour.

15 and 16 roughly show another embodiment, and in this embodiment, the grain guide body 35 of the deculmating grain transfer equipment 2 is connected to a motor or the like via a drive shaft 58. It is operatively connected to a drive device 59, and the drive device 59 rotates the pill guide 35 to adjust the degree of opening of the pill receptacle 4. Then, a sorting tube 1 is placed at the bottom of the intermediate shelf 3.
A grain sensor S-4 is provided for detecting the layer thickness of grains in the grain, and the drive device 59 is actuated by the output generated by this grain sensor 5-=1 upon detection of grains. It is configured to adjust the opening degree of the grain receiving port 4 of the culm removal transfer device 2 via the culm removal guide member 35.

According to the above configuration, during the sorting operation, when the grains circulating in the sorting tube 1 are in an appropriate amount, the grain sensor 4J
--S-4 does not detect any grains and the drive device 59 is inactive.

If the amount of grains circulating in the sorting tube 1 is too large, the grain sensor S-4 detects the grains.

When the grain sensor S-4 detects grains, the drive device 59
is activated, the dosed grain guide 35 is operated to close the weighing grain receptacle, and the number of grains falling into the dehulling grain transfer device 2 is reduced. Therefore, the amount of finished powder falling into the n+a
+ It is possible to prevent the mixing of dust powder.

J3, in FIGS. 6 to 16, the same reference numerals as in FIGS. 1 to 5 indicate the same components.

16- As is clear from the above explanation, according to the configuration of the first invention, the adjustment of the grain receiving port of the dehulled grain transfer device and the mixed grain receptacle of the intermediate dehulled grains is configured to be interlocked. Therefore, by adjusting the grain removal socket, the mixed grain socket will also be adjusted, maintaining the proper state of both, improving the sorting accuracy, and making the adjustment easy.

According to the configuration of the second invention, when ω of the mixed grains flowing down the intermediate shelf is more than or less than a predetermined digit, the mixed grain receptacle of the intermediate shelf is automatically adjusted accordingly. The amount of mixed grains falling into the mixed grain receptacle is adjusted accordingly.
It is easy to make the layer thickness of the mixed grains flowing through the intermediate shelf uniform, and the mixed flow returned from the intermediate shelf to the sorting cylinder is also approximately constant, so that the mixed grains in the sorting cylinder do not rapidly increase or decrease suddenly. Therefore, the sorting in the sorting tube is carried out in a stable state, and there is less unfiltered flow mixed into the dosage flow receptacle, and at the same time, the IB2B2 grain receptacle is adjusted together with the grain combining receptacle, which improves work efficiency. You can also try it out.
