Detailed Description of the Invention "Industrial Application Field" The present invention uses a sorting plate tilted back and forth as well as left and right to swing and separate the grains into brown rice and paddy while the grains flow down on the sorting plate. This invention relates to a partition plate control device for an oscillating sorter that separates and sorts.

"Prior art" Previously, Utility Model Application No. 52-14175 and Utility Model Application No. 55-17
As shown in each publication of No. 788111, it is equipped with a brown rice and paddy partitioning plate that separates the grains sorted by the swinging sorting plate into brown rice, mixed rice, and paddy and takes them out. There was a technology to displace the brown rice partition plate in the direction of movement.

"Problems to be Solved by the Invention" The oscillating sorting plate separates grains into brown rice and paddy based on differences in grain shape, surface friction resistance, and specific gravity. Brown rice, which has a large resistance force and a high specific gravity, gathers in the lower layer of the grain layer on the shaking side of the sorting plate, while paddy, which has a large grain shape, a small surface friction resistance force, and a low specific gravity,
It gathers on the rocking side of the sorting plate in the upper layer of the grain layer.

あった。
In addition, when the inclination angle of the oscillating direction of the sorting plate is small, when the oscillating angle of the sorting plate is large, or when the amount of grains on the sorting plate is insufficient, in any case, the grain The grains tend to gather on the shaking side of the sorting plate, and the paddy that should be taken out from the shaking side of the sorting plate also moves to the shaking side, causing the paddy to be mixed in with the brown rice taken out from the shaking side, reducing the product value. .

Contrary to the above, when the inclination angle of the shaking direction of the sorting plate is large, or when the shaking angle of the sorting plate is small, grains tend to gather on the shaking side of the sorting plate and are not taken out from the shaking side. There was a problem in which the amount of brown rice increased and the sorting efficiency was reduced.

However, in the conventional technology, since the grain sensor was provided in the mixed rice layer close to the brown rice layer on the upper side of the sorting plate, it is difficult to detect mixed rice with significantly lower paddy contamination rate than on the lower side of the shaking plate. Therefore, even if there is a slight change in the paddy mixture, the partition plate will not be able to provide an accurate response, and unless the paddy mixture at this sensor position changes significantly, the partition plate will not be controlled. In order to increase the mixing change, it is necessary to change the grain distribution state in the swinging direction on the sorting plate, and the inclination angle of the sorting plate is likely to be set too small or the swinging angle is likely to be adjusted to be too large. , problems arise such as not being able to easily obtain stable sorting work.

Therefore, in the prior art, three grain sensors were installed in close proximity to each other in order to solve the above problem, but initial settings that match the functions of all the sensors can be easily performed.
Since the detection accuracy of each sensor tends to be uneven, it is difficult to prevent erroneous control and reduce manufacturing costs, and it is also difficult to simplify handling operations such as adjusting the settings of the sensor output. There were other problems.

``Means for Solving the Problems'' However, one aspect of the present invention is to provide a oscillating sorter which is equipped with a paddy partition plate for separating grains sorted by an oscillating sorting plate into mixed rice and paddy, and which is driven by a drive device. In the device for displacing the rice partitioning plate in the swinging direction, a grain sensor for controlling the driving device is provided on the rice partitioning plate, and the grain sensor in the mixed rice layer near the paddy layer on the side under the swinging of the sorting plate is disposed. The present invention is characterized in that grains are configured to be detectable by the grain sensor.

``Function'' Therefore, the grain sensor can be made to respond sensitively to slight changes in the state of mixture of brown rice and paddy on the upper surface of the sorting plate, and accurate response of the grain cutting plate can be obtained even with slight changes in the mixture of paddy. As a result, it is possible to easily improve sorting accuracy and reduce manufacturing costs compared to conventional methods.

Simplification of handling operations such as setting adjustment of the grain sensor output can be performed more easily than before, and the inclination angle and swing angle of the sorting plate can be changed based on a sudden increase or decrease in the number of paddy detected by the grain sensor. can also be sensed, and the grain distribution state in the swinging direction on the upper surface of the sorting plate can be kept constant, making it possible to control the partition plate more stably than in the past.

On the other hand, contrary to the above, the paddy mixture ratio of this mixed rice is lower than the reference value and the amount of light detected by the sensor (71) is also adjusted by the adjuster (78).
), a negative light amount difference is generated, and the control circuit (80) outputs a signal to activate the reverse drive circuit (82), and the partition plate (45) is moved to the ear side. The partition width (T) on the brown rice side is automatically adjusted to a large value to effectively increase the amount of brown rice taken out.
