The comparator A3 is provided to output a forward/reverse signal of the motor αη to match the output of the motor (17) with the output of the motor (17). Through the switch Wt-
In addition, the reversing drive circuit of the motor αD is electrically connected to the comparator via the relay switch (47m) of the relay U7 and the switch nt-, so that when the relay switch (42) is turned on, the paddy sensor (

The structure is designed to achieve constant control of the amount of rice contained in the rice. Seriously, while connecting the motor forward rotation and reverse rotation manual switches μs- with manual priority to the relay (c),

Further, a =mon terminal (60c) of a grain sensor that is incorporated into the grain supply gutter @ of the F section of the hopper (4) and detects the supply amount of unsorted grains is connected to the operation power supply 6υKII, and this /S...'s normally closed and normally closed terminal (60b) (
601) When the partition plate (9) is automatically controlled by connecting it to the input side of the knot circuit 54-, the grain supply amount becomes more than a certain level, the sensor no longer detects this, and the sensor Q becomes constant. When the closed terminal (sob) is switched to Ill, the output from the operating power source is applied to the not circuit Q, and the excitation of the relay is de-energized via the 7-resonance 1-fing circuit 6I. Relay switch (42m

At the same time, a normally open reset switch a1) connected to the forward rotation drive circuit and linked like a normally closed switch is connected to the operating power source V-...b. 6m) and the input side of the buffer circuit, the output of the operating power supply ill is connected when the grain supply amount is below a certain level and the sensor is switched to the normally closed terminal (60b) as described above. By applying the voltage to one NAND circuit of the 7-rig circuit to excite the relay σI and operating the relay switch (701), the forward rotation drive circuit ( wealth)
Move the motor α7) fully forward and remove the partition plate t9J.
It is configured to move to the maximum movement position on the t-brown rice side. The present embodiment is constructed as described above, and the hopper (4) and each sorting plate (
3) While the grains supplied above are flowing along the inclination angle φ], the inclination angle ( The brown rice layer ^ is concentrated on the shaking side of α), the paddy layer (6) is concentrated on the shaking side, and the mixed rice layer Ω is concentrated in the middle. This is separated by the partition plate (t9) (IG) at the end of the flow and taken out respectively, and the position +!lII# of the partition plate (9) at the end of the sentence is determined by the paddy detection operation of the mixed rice by the paddy sensor (to). The amount of 11115!F contained in the mixed rice flowing down below the position is higher than usual, and the paddy mixing ratio is higher than a certain standard value. In this case, when detecting the difference in light intensity reflection between brown rice and paddy, the reflectance increases in proportion to the total amount of paddy, so the detection value at the sensor country also increases, and the output of the potentiometer υ increases. generates an output difference between the forward rotation drive circuit n
A t-crop signal is output. As a result, the partition plate (9
) is placed on the brown rice side, and this brown rice side partition is adjusted to a small size to prevent paddy from being mixed into the brown rice side. is lower than the reference value and the output value of the amount of reflected light detected at the center is also small, the comparator (43) reverses RX@
A signal to activate the circuit is output and the partition plate (9)
is gathered to the paddy layer, and the pressure inside the brown rice side partition is greatly adjusted to increase the guiding pressure of the amount of brown rice taken out. During this operation, the supply of unsorted grains was insufficient and the sorting plate t3J
When the upper grain layer becomes thinner, the grains are concentrated on the shaking side as a whole due to the returning movement of the sorting plate (3) and its rough sorting surface, without any layer shear or floating phenomenon. This causes the inconvenience of poor sorting. Therefore, when the amount of grains in the hopper (4) decreases and the flow rate of grains flowing through the supply gutter (51) becomes below a certain level, the sensor I switches to the normally closed terminal (60b) II. Similar to the manual switch (G) and (C) operations, the output from the operating power supply 6υ is applied to the knot circuit 5 and the 79g 70
The relay (6) is de-energized via the switching circuit ω and its automatic control is interrupted. At the same time, an operating power source is connected to one side/door circuit of the fritsuno frog circuit.
An output from the relay (7Qt) is applied to energize the V-switch (70@) t'' and turn it off. As a result, the relay 4 is energized and the relay switch (45a) t is turned off.
-Switch to this circuit side and m forward rotation drive circuit t441t-
Activate the motor ttnt and rotate it in the forward direction to move the partition plate (9) to the maximum limit on the brown rice side where the switch is activated, thereby minimizing the partition width on the brown rice side. Move the most valuable brown rice to 1! At 9, the rod (7), which moves together with the partition plate (9), activates the switch (to) to stop the drive IIb of the motor (I7), and activates the reset switch συ to reset the 7th litho 1st stage. The output of the operating power supply 6υ is applied to the other knot circuit of the 0 knob circuit to deenergize the relay σQ and return the relay switch (70aJt to OFF). When the grains are filled again and the amount of grains flowing through the supply @ (g) increases to a certain level or more and reaches l!!7t, the sensor 111r is switched to the normally open terminal side by the grain layer, and the power supply 6υ is switched to the normally open terminal side. The output from the clip frog circuit 6 is applied to the knot circuit (b).
The relay is energized again via G, and the relay switch (42m) is turned on to automatically control the partition plate (9).0 As is clear from the above embodiments, the present invention In addition, on the sorting board tilted left and right (sorting device + 2 that drives the 3J to swing and separate grains into brown rice and paddy), when the supply of unsorted grains is below a certain level, brown rice and paddy are separated. Since it is equipped with a grain sensor that moves the partition plate (9) that separates the brown rice to the largest brown rice side, it is possible to eliminate the decline in sorting performance that occurs when the supply of unsorted grains is insufficient. Stable sorting work can always be carried out under a constant condition O, and therefore the sorting accuracy can be maintained at a constant level, resulting in remarkable effects such as improved work efficiency and quality of sorted grains.
