A partition plate movement adjusting rod 28 is provided on the brown rice partition plate 18.
Is attached and the partition plate adjusting motor 29 is normally or reversely rotated, so that the brown rice partition plate 18 can be moved and adjusted to the horizontal swing-up side 15d15c or the swing-down side 15d. A sensor case 31 containing a paddy / brown rice discrimination sensor 30 is reciprocally attached between the brown rice partition plate 18 and the paddy partition plate 19, which are the non-uniform distribution basins of mixed rice, and swing selection is performed. Grains that flowed down from the discharge side of the plate 15
It is a structure that flows into the sensor case 31, and is a paddy composed of a reflective or transmissive optical element in the sensor case 31.
The brown rice discrimination sensor 30 detects the type of paddy / brown rice or the ratio of paddy / brown rice.

The detection information of the paddy / brown rice discrimination sensor 30 is composed of a CPU including a control section, an arithmetic section and a register section, and a memory section of a program memory and an arithmetic memory via an input interface. The configuration is input to the arithmetic control unit 32, and the arithmetic control unit 3
2 through an output interface, a partition plate adjusting motor 29, a sensor movement adjusting motor 33, a sorting plate inclination adjusting motor 34, a brown rice switching valve 35 (brown rice separated by the brown rice partition plate 19 and taken out of the machine) In this configuration, a control command signal is output to the switching valve adjusting motor 36 that switches between the take-out state and the in-machine circulation state.

Next, the control contents of the arithmetic control unit 32 will be described. The start of the hulling / sorting operation is detected by starting a driving motor (not shown) of the hulling / sorting machine, or a sensor (not shown) is used to detect the opening of the paddy supply control valve 37 of the hulling section 1. When it is detected by, for example, the arithmetic control unit 32 outputs a steep slope adjustment command signal for adjusting the swing selection plate 15 to a steep slope, and causes the paddy / brown rice discrimination sensor 30 to be near the paddy partition plate 19 on the swinging side 15d. The swaying side movement command signal for moving the sensor is output, the sorting plate tilt adjusting motor 34 is driven, and the swinging sorting plate 15 is adjusted to a steep tilt side by a predetermined angle via the tilt adjusting means 38. The discrimination sensor 30 is moved to the swinging side 15d by the sensor movement adjustment motor 33, and the paddy partition plate 19 is moved.
Moved to the vicinity of. When the mixed rice is supplied to the rocking sorting plate 15, the rocking sorting plate 15 is steeper than the standard tilt angle, so that the mixed rice is distributed only on the rocking side 15d in a state where the layer thickness is relatively thick. While flowing to the discharge side 15b in the vertical direction, the flow state of the grain is detected by the paddy / brown rice discrimination sensor 30 located near the paddy partition plate 19. If the detection result is paddy detection,
The arithmetic control unit 32 outputs a gentle inclination adjustment command signal for adjusting the swing selection plate 15 to a predetermined angle gentle inclination side, and the selection plate inclination adjustment motor 34 adjusts it to a predetermined angle gentle inclination side.
Similarly, when the paddy / brown rice discrimination sensor 30 detects the paddy, the swing selection plate 15 is repeatedly adjusted to the side of the gentle inclination by the same angle as described above. Next, the detection result of the paddy / brown rice discrimination sensor 30 is a predetermined ratio (for example, the ratio of brown rice 3 to paddy 7).
When the mixed state of unhulled rice and brown rice is detected and falls within the range of the reference value, it is determined that the rocking sorting plate 15 has an appropriate inclination, and the arithmetic control unit 32 prompts the rocking sorting plate 15 to move rapidly. A steep slope adjustment stop command signal for stopping the slope adjustment is output, the adjustment of the sorting plate slope adjusting motor 34 to the steep slope side is stopped, and the paddy / brown rice discrimination sensor 30 is shaken near the brown rice partition plate 18 on the upper side 15c. A sensor upward movement command signal for moving the sensor is output, the sensor movement adjusting motor 33 moves the paddy / brown rice discrimination sensor 30 to the vicinity of the brown rice partition plate 18, and further,
A control command signal for switching the brown rice switching valve 35 from the in-machine circulation state to the out-of-machine removal state is output from the arithmetic and control unit 32, and the brown rice switching valve 35 is switched to the out-of-machine removal side by the switching valve adjusting motor 36. , Shift to normal working state.

When the detection result of the paddy / brown rice discrimination sensor 30 detects the mixed state of paddy / brown rice at a predetermined ratio and falls within the range of the reference value, the rocking / sorting plate is considered to have an appropriate inclination. Although it is determined, the paddy partition plate 19 is often set by manual adjustment, and it may move from the standard position to the rocking side 15c or the rocking side 15d. If the reference value is manually or automatically corrected, the proper selection state of the swing selection plate 15 is accurately determined, and the selection accuracy is improved. Next, the operation shifts to the brown rice partition plate control for normal work. The sensor case 30 is reciprocally moved between the brown rice partition plate 18 and the paddy partition plate 19 by a sensor movement adjusting motor 33, and the sensor case 30 is provided from the vertical discharge side 15b of the swing selection plate 15.
Grains flow down inside, and the distinction between paddy and brown rice is detected by the paddy / brown rice discrimination sensor 30. When the detected value is input to the arithmetic control unit 32, this detected value is compared with the partition plate control reference value, and if the detected value is within the range of the partition plate control reference value, a control command signal is output. However, the brown rice partition plate 18 holds the position as it is, and when the detected value has more (or less) paddy with respect to the partition plate control reference value, the calculation control unit 32 causes the partition plate adjustment motor 29 to swing. A movement command signal to the lower side 15d (or the upper side 15c) is output, and the brown rice partition plate 18 is moved to the lower side 1 via the partition plate movement adjusting rod 28.
The movement is adjusted to a predetermined distance of 5d (or swinging upside 15d15c) to prevent the paddy rice from being mixed with paddy.

In this embodiment, when the swing sorting plate 15 is started to be sorted, the swing sorting plate 15 is positioned near the paddy partition plate 19 with a lateral inclination greater than the standard tilt angle. The horizontal inclination angle was gradually adjusted by detecting the grain flow state of the paddy / brown rice discrimination sensor 30, but the vertical inclination angle was set to be steeper than the standard,
The inclination angle may be gradually adjusted gradually in relation to the detection result of the paddy / brown rice discrimination sensor 30.

The refined brown rice is fried in a weighing tank elevator 51 through the stone removing machine 50 and stored in a weighing tank (not shown). A brown rice jam sensor 53 is installed in the hopper 52 of the grain sorter 48 in the subsequent stage of the swing sorting device 3.

When the brown rice clogging sensor 53 detects clogging of brown rice, the brown rice switching valve 55 provided in the brown rice extraction passage 54 of the swing sorting device 3 is switched to the circulation side.
The brown rice is circulated to the swing sorting device 3 via the mixed rice spiral 46 and the paddy sorting elevator 44, and the grain sorting elevator 47 and the hopper 52 of the grain sorting device 48 in the subsequent process of the swing sorting device 3.
It is possible to prevent clogging.

Further, a grain sensor 57 is provided in the distribution gutter 16 of the swing sorting device 3, and when the grain sensor 57 detects no grain, the drive of the swing sorting device 3 is stopped, and the swing sorting device 3 is stopped. When the partition plate sensor 58 detects the movement of the brown rice partition plate No. 3 (not shown) to the uppermost sway 15c, the brown rice switching valve 55 is configured to be switched to the circulation side. Although consideration is given to the excess or deficiency of the grain of the sorting device 3, the grain sorting machine 48 does not consider the clogging phenomenon of the grain which is a subsequent process of the swing sorting device 3, and thus the grain sorting elevator. No. 47 will be clogged with grains and will cause the system to stop. There was. However, when the brown rice clogging sensor 53 detects clogging of brown rice, the brown rice switching valve 55 provided in the brown rice extraction passage 54 of the swing sorting device 3 is switched to the circulation side, so that the grain sorting elevator 47 is prevented from clogging. Thus, the drawbacks of the conventional device can be eliminated.
