(Problems to be Solved by the Invention) The prior art includes: a. An unhulled rice detector consisting of a photo sensor or the like is attached to a swinging partition plate.

b Four photo sensors are attached to the swinging part.

c The photo sensor detects 4 to 5 layers of grain.

There is a problem with this point.

Since the unhulled rice detection body consisting of a photo sensor is attached to the swinging part, the unhulled rice detection is structured to detect the unhulled rice while swinging, so accurate detection is not possible.

Also, since multiple photo sensors are attached, the structure becomes larger.

Also, since multiple photo sensors are installed, the structure becomes complicated.

Also, since multiple photo sensors are installed, the price will be high.

In addition, since the unhulled rice detector has a structure in which grains flow down in four to five layers, unhulled rice that is hidden by the grains cannot be detected, resulting in inaccurate detection.

(Means for solving the problem) Therefore, the present invention reciprocates the sorting plate 1 in the left-right direction and separates the mixed grains supplied onto the sorting plate 1 into the shaking side 4 and the shaking back side 5. , the discharge side 3 of the sorting plate 1 is opened over the entire width, partition plates 10 and 11 are provided on the discharge side 3, a brown rice outlet 12 is provided on the rocking side 4, and an unhulled rice outlet 13 is provided on the rocking side 5. and a mixed rice outlet 14 is formed in the middle thereof, and the partition plate 10 provided between the brown rice outlet 12 and the mixed rice outlet 14 is configured to be automatically moved horizontally by an automatic movement adjustment device. In the swing type grain sorting device, a chute 17 through which brown rice flows down in a single layer is provided in the non-swinging part of the brown rice flow path from the brown rice outlet 12, and a photo sensor is installed below the discharge end 18 of the chute 17. 19 and a background 20 are installed, and an automatic movement adjustment device for the photo sensor 19 and the partition plate 10 is installed to automatically move the partition plate 10 to the rocking side 4 when the photo sensor 19 detects unhulled rice; This is a separated grain take-out device in a swing-type grain sorting device which is connected so as to automatically move to the swing-back side 5 when no unhulled rice is detected for a certain period of time.

(Example) 1 is a sorting plate with an uneven surface, and the planar shape is square. One side is the supply side 2, and the other side opposite to it is the discharge side 3. The supply side 2 is sloped higher than the discharge side 3. are doing. Moreover, one side in the left and right direction with respect to the direction connecting the supply side 2 and the discharge side 3 is formed as a swing side 4, and the other side is formed as a swing back side 5, and the swing side 4 is inclined higher than the swing back side 5. The sorting plate 1 is placed on the underframe 6,
It is supported by diagonal rods 7 and 8, and when the eccentric shaft 9 is rotated, it reciprocates as shown by the arrow W.

In this state, if mixed grains consisting of brown rice and unhulled rice are fed near point P, the brown rice will be placed on the rocking side 4 as shown by arrow A.
The unseparated rice flows to the shaking side 5 as shown by arrow B, and the unseparated mixed rice flows in the middle as shown by arrow C.

Therefore, the discharge side 3 is fully opened, and the partition plate 10,
11, and a brown rice outlet 12 on the rocking side 4.
An unhulled rice outlet 13 is formed on the shaking side 5, and a mixed rice outlet 14 is formed in the middle thereof.

However, the positions of the partition plates 10 and 11 are not fixed, but are attached so that they can slide in the left-right direction depending on the state of drifted flow.

The partition plates 10 and 11 of the present invention are also adjustable and attached, and their configuration is such that a branch channel 16 is formed in the non-swinging part of the brown rice channel of the brown rice outlet 12, and a branch channel 16 is formed in the non-swinging part of the brown rice channel of the brown rice outlet 12. A paddy rice detection body 21 consisting of a single photo sensor 19 etc. is attached, and the paddy rice detection body 21
and an automatic movement adjustment device for the partition plate 10. When unhulled rice is mixed in the branch flow path 16, the partition plate 1
0 is automatically moved to the swinging side 4, and the partition plate 10 is automatically moved to the swinging side 5 when no unhulled rice is mixed in the branch flow path 16 for a certain period of time. This is what I did.

That is, as shown in FIG. 2 and subsequent figures, a branch channel 16 is formed in the non-swinging portion of the brown rice channel 15 taken out from the brown rice outlet 12, and a chute 17 is provided in the branch channel 16 to remove the brown rice. The group forms a flowing part, and an unhulled rice detector 21 consisting of a photo sensor 19, a background 20, etc. is installed near the discharge end 18 of the rice, and a rice detector 21 is installed in the vicinity of the discharge end 18 to detect the unhulled rice taken out from the brown rice outlet 12. It detects whether or not unhulled rice is mixed in.

Of the partition plates 10 and 11 provided on the discharge side 3 of the sorting plate 1, the partition plate 10 installed between the brown rice outlet 12 and the mixed rice outlet 14 is connected to the shaking side 4. Rotating threaded rod 2 mounted between sides 5
2, and when the rotary threaded rod 22 rotates forward or reverse, the partition plate 10 is formed to move toward the swinging side 4 or the swinging back side 5. 23 is a threaded portion, and 24 is a threaded cylinder that fits therein. A motor 25 is attached to the rotating threaded rod 22, and the motor 25 is connected to the photo sensor 19 via an arithmetic circuit 26. The arithmetic circuit 26 does not have a complicated structure, and a very ordinary one is used, which is shown in FIGS. 3 and 4.

FIG. 3 shows an example of the arithmetic circuit 26 installed between the unhulled rice detector 21 and the motor 25.
This is an example in which 9 is attached. The unhulled rice detector 21 is
Every time unhulled rice flowing through the chute 17 is detected, a pulse signal 30 is output. The timer 27 indicates the set time to the preset counter 29.
Therefore, the preset counter 29 counts the number of unhulled rice within the time set by the timer 27,
When the set number has been reached (for example, 3 grains), the motor 25 is energized to rotate in the normal direction, and the motor 25 is rotated in the normal direction to move the partition plate 10 in the four swinging directions.

The timer 28 introduces the pulse as a reset output, and when there is no pulse at all within the time set by the timer 28, the motor 25 is energized in the reverse direction.

The timer 31 and the timer 32 are connected to the motor 25.
The rotation is stopped after a certain period of time.

(Function) A part of the brown rice taken out from the brown rice outlet 12 is
When the brown rice flows into the non-oscillating branch channel 16 formed in the brown rice channel 15, is further rectified by the chute 17, and is discharged one by one from the discharge end 18, the photo sensor 19 and background 2
The amount of unhulled rice mixed in the brown rice group is accurately detected by the unhulled rice detector 21 made of 0 etc.

Therefore, during the time set by the timer 27, the pulse signal 30 is applied to the preset counter 29, and when the number (for example, 3) reaches the set number, the motor 25 is energized for normal rotation. Then, the rotary threaded rod 22 is rotated in the normal direction for a time set by the timer 31 (a short time) to move the partition plate 10 to the swinging side 4. Therefore, the grains flowing on the chute 17 are automatically adjusted to be only brown rice grains, and no unhulled rice is mixed into the brown rice channel 15.

If there is no unhulled rice mixed in the finished brown rice for a certain period of time, the unhulled rice detector 21 will not generate a pulse, so there will be no pulse within the time set by the timer 28, and therefore, After being reset, the motor 25 is energized for reverse rotation, the rotating threaded rod 22 is reversed for a short period of time set by the timer 32, the partition plate 10 is moved to the swinging side 5, and the brown rice outlet 12 is opened. It maximizes the width and efficiently removes brown rice.

(Effects) Conventionally, in a rocking type grain specific gravity sorting device in which a sorting plate is reciprocated diagonally up and down to separate the mixed grains supplied onto the sorting plate into a shaking side and a shaking back side, the sorting plate The discharge side is opened over the entire width, and the discharge side is partitioned by a partition plate to form a brown rice outlet on the yawori side, an unhulled rice outlet on the yawori side, and a mixed rice outlet in the middle. The partition plate provided between the take-out port and the mixed rice take-out port is configured to automatically move laterally by an automatic movement adjustment device, and the partition plate provided between the brown rice take-out port and the mixed rice take-out port is configured to swing. A hulled rice detector consisting of a plurality of photo sensors for detecting grains flowing down in four or five layers is attached to the hulled rice detector, and an automatic movement adjustment device for the partition plate is installed on the hulled rice detector to detect grains flowing down in four or five layers. A device for taking out separated grains in a swing type grain specific gravity sorting device in which the partition plate is coupled to automatically move to the swinging side is disclosed in the earlier patent application No. 1983-26146. There is.

The prior art is a. A paddy/rice detector consisting of a photo sensor or the like is attached to a swinging partition plate.

b Four photo sensors are attached to the swinging part.

c The photo sensor detects 4 to 5 layers of grain.

There is a problem with this point.

Since the unhulled rice detection body consisting of a photo sensor is attached to the swinging part, the unhulled rice detection is structured to detect the unhulled rice while swinging, so accurate detection is not possible.

Also, since multiple photo sensors are attached, the structure becomes larger.

Also, since multiple photo sensors are installed, the structure becomes complicated.

Also, since multiple photo sensors are installed, the price will be high.

In addition, since the unhulled rice detector has a structure in which grains flow down in four to five layers, unhulled rice that is hidden by the grains cannot be detected, resulting in inaccurate detection.

However, in the present invention, the sorting plate 1 is reciprocated in the left-right direction, the mixed grains supplied onto the sorting plate 1 are separated into the shaking side 4 and the shaking back side 5, and the sorting plate 1
The discharge side 3 is opened over the entire width, and the discharge side 3 is opened over the entire width.
Partition plates 10 and 11 are provided on the sides, a brown rice outlet 12 is formed on the rocking side 4, an unhulled rice outlet 13 is formed on the rocking side 5, and a mixed rice outlet 14 is formed in between. A partition plate 10 provided between the mixed rice outlet 14 is used to separate the brown rice flow path from the brown rice outlet 12 in a swinging grain sorting device configured to automatically move horizontally using an automatic movement adjustment device. Chute 17 where brown rice flows down in a layer on the swinging part

Separated grains in a swing-type grain sorting device in which the partition plate 10 is coupled to automatically move to the shaking side 4 and automatically move to the shaking side 5 when no unhulled rice is detected for a certain period of time. (a) In the present application, the flow is made to flow to the branch channel 16 in the non-swinging part, so the chute 17 provided there does not swing. Therefore, the grain can be flowed in a layer where it can be easily detected.

(b) The prior application has a structure in which unhulled rice is detected while swinging, so accurate detection cannot be achieved, but the present application has a structure in which unhulled rice is detected stationary, so accurate detection is possible.

C. The previous application has a large structure because multiple photo sensors are installed, but the present application can be implemented with one photo sensor and the background, so it can be made smaller and has a simpler structure.

D. The previous application is expensive because it has multiple photo sensors, but the present application can be implemented with one photo sensor in the background, so it can be done at a lower cost.

E. The previous application detects the grains flowing down in 4 to 5 layers, so the unhulled rice that is hidden behind the grains cannot be detected, resulting in inaccurate detection, but the present application detects the grains flowing down in 1 layer. Because it uses a sensor, there is no unhulled rice that is hidden behind the grains, and it can be detected accurately.
