Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic control device for a grain hulling plant.

In other words, in a hulling grain sorting plant configured to sort mixed rice fed from a huller using a swinging sorter and feed brown rice to a brown rice tank, the brown rice tank is filled with brown rice. The drive motor of the oscillating sorter can be stopped to stop the sorting work, especially when a weighing machine or the like is installed below the brown rice tank to weigh the rice and fill it into bags. To automatically control the feeding of brown rice to a brown rice tank according to the situation, and to perform the feeding in a well-balanced manner without causing any trouble.

Next, the embodiment shown in the drawings will be described.

The drawing shows the main parts of the hulling grain sorting plant, in which the lower part of the paddy supply tank 1 is connected to the lower part of the paddy elevator 8 via an automatic shutter 5, and the upper part of the elevator 8 is connected to the upper part of the paddy tank 3. In communication, the lower part of the paddy tank 3 is connected to the upper part of the huller 2 having the agitation roll 2a through an automatic shutter 5, and an upper limit level gauge and a lower limit level gauge are installed at the upper and lower positions in the paddy tank 3. The level meter L2 is attached, and when the upper limit level meter L comes into contact with the paddy surface and turns on or off, the automatic shutter 5 closes or opens, and when the lower limit level meter L turns on or off, the automatic shutter 52 It is configured so that it opens and closes. The upper part of the mixed rice elevator 9, which is connected to the lower part of the huller 2, is connected to the upper part of the mixed rice tank 5, and a large number of grain sorting plates 4a are stacked and tilted, and the drive motor 6 performs rocking sorting. The lower part of the mixed rice tank 5 is connected to the upper part of the slope of the machine 4, and upper limit level gauges L are installed at the upper and lower positions in the tank 5. and lower limit level meter L. However, when the upper limit level meter L comes into contact with mixed rice and turns on and off, the automatic shutter 52 opens and closes, and the lower limit level meter L. When the drive motor 6 is turned on or off, the drive motor 6 and the supply are started or stopped. Further, the brown rice sorted by the swing sorter 4 is raised by the brown rice elevator 10, the mixed rice is fed to the mixed rice elevator 9 as shown by arrow A, and the paddy is sent to the paddy elevator 8 as shown by the arrow port. configured to deliver.

A rice sorter 12 driven by a motor 11 is installed in the upper and lower parts of the brown rice elevator 10, and a brown rice tank 7 is installed in the upper and lower part of the good brown rice elevator 13 that communicates with the take-out side of the rice sorter 12. A weighing machine 15 for weighing and filling the bag 14 is installed below it, and an upper level meter is installed at the top of the brown rice tank 7! is installed so that the drive motor 6 is stopped and started when the upper level meter L5 is turned on or off.

Therefore, during the operation, the paddy supplied to the paddy supply tank 1 is fed from the paddy tank 3 to the hulling machine 2, demixed, and then supplied from the mixed rice tank 5 to the swinging sorter 4. The sorted brown rice is sent to the brown rice elevator 10, the mixed rice to the mixed rice elevator 9, and the paddy to the paddy elevator 8.The brown rice carefully selected by the rice sorter 12 is sent from the brown rice tank 7 to the weighing machine 15. After weighing, the products are packed into bags 14.

In this state, when paddy is sufficiently fed into the paddy tank 3 and the upper limit level meter L1 turns on, the automatic shutter S1 closes, and when it turns off, it opens. When the lower limit level meter L2 is turned on due to contact with paddy, the automatic shutter S2 opens and feeds the paddy to the huller 2, and when the amount of paddy decreases and it turns off, the automatic shutter S2 closes and feeds the paddy. Stop and huller machine 2
The supply of paddy to can be automatically controlled.

In addition, in the mixed rice tank 5 into which the mixed rice is fed from the huller 2, the tank is full and the upper limit level meter L3
When turned on, automatic shutter S2 closes and stops feeding to the mixed rice tank 5 without doing the hulling work, and when the mixed rice level goes down and turns off, automatic shutter S2 opens and allows the hulling work and mixing. The rice can be fed to the rice tank 5, and the lower limit level meter L4 turns on. In the puddle state, the drive motor 6 is driven and the mixed rice can be fed from the mixed rice tank 5 to the swinging sorter 4. When the amount is low and the rice is turned off, the drive motor 6 is stopped and the feeding is stopped. It can be stopped.

Furthermore, in the brown rice tank 7, when the upper level reaches two full, the upper level meter L5 turns on and stops the drive motor 6, and by stopping the drive motor 6, each grain selection plate 4a swings. The oscillating sorting work is stopped and each grain sorting plate 4
The brown rice and paddy that had been flowing on the lower side of the slope on the top a come to rest on the grain sorting plate 4a, and the supply of brown rice to the brown rice tank 7 can be stopped, and the brown rice is packed from the weighing machine 15 into bags. When the amount in tank 7 gets low, the upper level meter! is turned off, and the drive motor 6 is started again to perform the oscillating sorting, and at the same time, it is possible to start feeding good brown rice to the brown rice tank 7.

As described above, the present invention provides a hulling and grain sorting plant configured to sort mixed rice fed from a huller 2 using a swinging sorter 4 and feed brown rice to a brown rice tank 7. There is an upper level meter at the top of brown rice tank 7! Equipped with an upper level meter! Since the drive motor 6 of the oscillating sorter 4 can be stopped and activated by the operation of the brown rice tank 7, the drive motor 6 is stopped and the oscillating sorting operation is stopped when the brown rice tank 7 is filled to the top. The supply of brown rice to brown rice tank 7 can be stopped by
When the amount in the brown rice tank 7 becomes low, the drive motor 6 can be started again to perform the oscillating sorting process and to start feeding the brown rice to the brown rice tank 7. Since the supply of brown rice to the brown rice tank 7 is stopped, there is no need to run the oscillating sorter idly while it is stopped, especially when a weighing machine or the like is installed below the brown rice tank 7 to weigh the rice and fill it into bags. This apparatus has the feature that it can automatically control the feeding of brown rice to the brown rice tank 7 according to the state of the bagging and filling operation, and can perform the operation in a well-balanced manner without causing any trouble.
