(Operation) Next, the operation will be described.

The huller of the present invention is as shown in FIGS. 1 and 2, but the main devices are the following five.

.. Paddy rice supply elevator 51 .. Upper shutter 62 .. Paddy rolls 63, 64 .. Swing selection plate 21 .. Finishing rice lifter 89. A control mechanism is provided at a desired position of the paddy huller of the present invention. However, the control mechanism always operates in the following order.

When starting operation, start in the order of. That is, first, the finishing rice elevator 89 is started, then the paddy rice supply elevator 51 is started, then the rocking sorting plate 21 is rocked, and then the paddy rolls 63 and 64 are rotated, and finally the upper part. The shutter 62 is opened.

After that, when the paddy rice is fed into the paddy rice supply hopper 56, the paddy rice is supplied from the paddy rice supply port 55 to the lower part of the paddy rice supply elevator 51 and fried by the bucket conveyor 54,
What is stored in the upper tank 58 through the input port 57 of the elevator 51 and overflows returns to the return port 87 through the overflow 61.

Since the upper shutter 62 is open, the transfer roll 67
, The slant plate 68 flows down, and the fixed hull roll 63
And the moving hull roll 64 are hulled and hulled, diffused by the diffuser 72, wind-selected in the wind-selecting chamber 71, the chaff is sucked and removed by the suction windmill 73, and the mixed rice is transferred by the transfer plate 79. Is supplied to the swing sorting plate 21 of each stage and is sorted,
The unpolished rice flows from the unpolished rice outlet 28 through the unpolished rice trough 88 into the finished rice elevator 89, and is stored in the finished rice tank 90. The unhulled rice flows out from the unhulled rice outlet 30 of the rocking and sorting plate 21 into the screening net 92, the scrap rice is removed, and only the unhulled rice is returned to the return port 87.

Then, when the operation is stopped, they are stopped in the order of. That is, when the operation is started, the finishing rice elevator 89 that is operated first is rotated to the end, the upper shutter 62 is first closed, and then the hulling rolls 63 and 64 are used.
Is stopped, then the oscillating selection plate 21 is stopped, then the paddy rice supply elevator 51 is stopped, and finally the finishing rice elevator 89 is stopped.

As described above, when the operation is started, starting in the order of is that if it is started all at once, there is a risk that an excessive current may flow due to excessive load, and that the finishing rice elevator 8
Even if brown rice is accumulated at the brown rice outlet 28 of the rocking sorting plate 21 by first starting 9, the rice is first taken out, and then the paddy rice supply elevator 51 is started to collect the paddy rice accumulated in the elevator 51. Is supplied to the upper tank 58 of the storage tank so as to be cleaned and new paddy rice can be supplied, and then the swinging and selecting plate 21 is swung before the hulling rolls 63 and 64 to perform complete sorting. Then, the hulling rolls 63 and 64 are rotated, and finally the upper shutter 62 is opened.

However, when stopped, the order is as follows. First, the upper shutter 62 is first closed in order to stop the supply of the raw material, and then the hulling rolls 63 and 64 are stopped because the hulling is not performed anymore. Even if residual rice remains on the rocking and sorting plate 21, the supply amount is small, so that the selection is defective and the operation is stopped. Finally, the paddy rice supply elevator 51 and the finished rice elevator 89 are stopped.

The same applies to abnormal cases.

(Effect) In the conventionally known one, the paddy rice feeding elevator is first operated, then the paddy roll, then the rocking sorting plate, then the finishing rice elevator, and then the others are sequentially operated with a time lag. Therefore, there is no effect at the time of the first operation, but various kinds of disasters occur when the work is performed once and then restarted.

For example, since there is a considerably large amount of residual rice on the rocking sorting plate surface, if it swings and flows out to the outlet,
The finished rice elevator, which is not rotating yet, is flooded and stuck.

As for the hulling roll and the rocking sorting plate, when the hulling roll is rotated first, a large amount of mixed rice is supplied to the rocking sorting plate that is not rocking, which causes a sorting failure.

However, in the present invention, the main components are the paddy rice supply elevator 51, the upper shutter 62, the paddy roll 63,
In the huller comprising 64, the rocking sorting plate 21, and the finishing rice elevator 89, when the operation is started, the finishing rice elevator 89, the paddy rice feeding elevator 51, the rocking sorting plate 21, the hulling rolls 63, 64 When the operation is stopped in the order of the upper shutter 62, when the operation is stopped, the upper shutter 62, the hulling rolls 63 and 64, the oscillating sorting plate 21, the paddy rice feeding elevator 51, and the finishing rice elevator 89 are stopped in this order, and an abnormal stop occurs. Also in this case, since the automatic operation control method of the hulling machine is performed in the same manner as the operation stop, the finishing rice elevator 89 is rotated before the paddy rice supply elevator 51 when the operation is started. , Even when the finish rice elevator 89 is filled with the finish rice,
Since the finishing rice elevator 89 rotates without being clogged and then the rocking sorting plate 21 is rocked, the remaining rice on the rocking sorting plate 21 can be gradually supplied to the finishing rice elevator 89, and then the hulling roll 6
Since the upper shutter 62 is opened after rotating 3, 64, smooth hulling can be performed from the beginning.

Further, when stopped, the upper shutter 62 is first closed, so that the supply of the raw material can be stopped even if the paddy rice supply elevator 51 is rotating, and then the paddy rolls 63, 64 are provided.
Since the hulling can be stopped, the hulling can be stopped, and then the swing selection plate 2
Even if there is leftover rice in 1, the rocking sorting plate 21 is stopped,
The unsorted rice is left as it is, and finally the paddy rice supply elevator 51
Then, the finishing rice elevator 89 is stopped and the taking out is stopped.
