Description

[Detailed Description of the Invention] The present invention relates to a device for removing leftover rice from a mixed rice tank in a rice hulling machine immediately before the end of the hulling operation.

Generally, when paddy is removed from the huller,
Mixed rice is a mixture of paddy, brown rice, etc., and this mixed rice is lifted up by an elevator and then supplied to a sorting unit such as Mangoku, where it is sorted into paddy, mixed rice, and brown rice. Then, the paddy is returned to the removal section, the mixed rice is re-supplied to the sorting section, and only brown rice is sorted and discharged outside the machine. By the way, in the sorting section, when the supply of mixed rice decreases, such as just before the end of the hulling operation, the sorting performance deteriorates and paddy gets mixed into the brown rice sorting area of the sorting section, causing the paddy to be lost along with the brown rice. There was a drawback that leftover rice that was not discharged outside the machine or sorted remained in the hulling machine forever. Therefore, the mixed rice whose supply amount has decreased, that is, the remaining rice, must be taken out of the machine. Conventionally, in order to take out the remaining rice, the side plate of the sorting section was removed and the remaining rice in the sorting section was taken out directly, or The mixed rice hopper that feeds the mixed rice lifted up by the elevator to the sorting section was closed, and the remaining rice stored in the hopper was taken out, but the work to take it out was troublesome and the work efficiency was poor. There was a drawback. In particular, when the sorting section is made to swing to form a swing sorting section that sorts the mixed rice, it is necessary to feed the mixed rice from above in order to simplify the transfer route for the mixed rice. The sorting section and supply hopper are located at a high level because the swinging link that swings the section must be provided below, and the grain sorting plate of the sorting section must be provided in multiple stages above and below. It was difficult and dangerous to take out leftover rice from the supply hopper.

In view of the above-mentioned circumstances, the present invention was devised to further overcome these shortcomings. There is no need for any troublesome operations such as opening the side plate of the sorting section, closing the mixed rice hopper that supplies the mixed rice to the sorting section, storing the mixed rice in the hopper, and taking it out directly. Even if the mixed rice hopper is located at a high place, we have developed a device for removing leftover rice from a huller that can safely, easily and reliably take out the leftover rice without any danger by simply operating the operating handle. This is what we intend to provide.

It communicates with the brown rice removal gutter 42. Further, 43 is a shutter provided at the outlet 30a of the mixed rice tank 30.

Next, the operation of the present invention constructed as described above will be explained. Now, when removing the paddy and recovering brown rice, when the worker throws the paddy into the paddy supply hopper 5, the introduced paddy is removed by the removal roller 4, and then the paddy is removed from the paddy receiving plate 6 and the grain-flowing plate. 7, it falls from the outlet 8 to the wind removal section 9 and is wind-selected. That is, in the air removal section 9, foreign matter such as dust with the lightest specific gravity is discharged out of the machine by the suction wind produced by the suction windmill 10, and then foreign matter such as scrap rice with the lightest specific gravity is air-selected. The waste rice is discharged outside the machine via the scrap rice discharge helix 22,
The mixed rice with a heavy specific gravity is transferred to the lower end of the mixed rice elevator 28 via the mixed rice transfer helix 27, and is further elevated by the mixed rice elevator 28 to the mixed rice connecting gutter 2.
9 and is supplied to the mixed rice tank 30. The mixed rice supplied to the mixed rice tank 30 falls in fixed amounts onto the mixed rice supply gutter 31 from the flow-down port 30a whose flow rate is adjusted by the shutter 43, and is transferred from the mixed rice supply gutter 31 to the swing sorting unit 2. The rice is fed onto the oscillating sorting plate 12 inside, and is oscillatingly sorted into brown rice, mixed rice, and paddy. And brown rice is transferred from brown rice sorting area A to brown rice transporter 1.
5, the brown rice is flown down from the brown rice guide gutter 16 at the transfer tip to the brown rice flow down gutter 18 via the flow plate 17, and is wind-selected by the brown rice wind sorting section 19, and the brown rice is passed through the brown rice guide gutter 18. The brown rice is guided to the lower end of the elevator 41, and then elevated by the brown rice elevator 41 and collected from the brown rice removal gutter 42. On the other hand, the paddy falls from the paddy sorting section C onto the paddy transfer body 23, is returned to the paddy supply hopper 5 via the paddy trough 24, and is again supplied to the removal section 1.

Further, the mixed rice falls from the mixed rice sorting section B onto the mixed rice transfer body 25, is transferred to the lower end of the mixed rice elevator 28 via the mixed rice flow down trough 26 and the mixed rice transfer screw 27, and is transferred to the mixed rice elevator 28 again. The mixed rice is lifted up by the tank 30 and fed back to the mixed rice tank 30.

In the above-mentioned series of hulling operations, since the amount of mixed rice supplied to the swinging sorter 2 is always regulated by the shutter 43 so that it is fixed, the mixed rice is lifted by the mixed rice elevator 28. When the amount of mixed rice becomes larger than the amount supplied to the oscillating sorter 2, the mixed rice is first stored in the mixed rice hopper 30 and then further stored in the mixed rice connection gutter 29. When the gutter 29 is also filled, the excessively supplied mixed rice flows down into the backflow pipe 32 from the backflow port 32a opened below the connection port 29a of the mixed rice connection gutter 29, and is transferred to the backflow pipe 32 by the switching valve 33. Mixed rice elevator 28 via unblocked communication pipe 32b
It flows down to the lower end and is circulated and supplied. Therefore, by adjusting the amount of mixed rice supplied by reducing the amount removed by the removal section 1, continuous hulling work will not be possible, but it will also prevent the mixed rice from leaking out of the machine. Damage to each part can be prevented.

On the other hand, just before the end of the hulling operation, the supply of mixed rice to the oscillating sorting section 2 gradually decreases, and if the mixed rice continues to be supplied as it is, not only will the sorting performance in the oscillating sorting section deteriorate; If the mixed rice only circulates inside the machine, it will become impossible to sort, but the device of this invention anticipates when the supply of mixed rice decreases and shuts down just before the sorting performance deteriorates. 43 is closed and the operation handle 37 is moved upward in the X direction against the tension bomb 38a, the opening/closing plate 35 is rotated downward and the side plate 30b is opened. Therefore, the mixed rice whose supply amount has decreased, that is, the remaining rice, flows down the opening/closing plate 35 and flows into the backflow pipe 32 from the communication funnel 39 without being stored in the mixed rice tank 30. At this time, the switching valve 33 closes the communication pipe 32b side in conjunction with the upward movement of the operation handle 37, and closes the discharge pipe 3.
Since the 2c side is open, the remaining rice that has flowed into the backflow pipe 32 is not supplied to the lower end of the mixed rice elevator 28, but is discharged and collected outside the machine via the discharge pipe 32c. . Therefore, if work continues in this state for a while, the remaining rice can be completely removed from the machine and recovered.

In summary, the present invention provides a rice hulling machine in which a mixed rice tank is provided at a high position above the oscillating sorting section, and a backflow pipe is provided to allow excess mixed rice supplied to the mixed rice tank to flow back into the mixed rice elevator. An opening/closing plate is provided in the mixed rice tank, and the opened opening/closing plate forms a remaining rice removal path communicating with the backflow pipe, and a rotatable switching valve is provided on the backflow pipe to control the conveyance path of the backflow pipe. The opening/closing plate is configured to be switchable from the mixed rice elevator side to the discharge pipe side opening outside the machine, and the opening/closing plate and the switching valve are provided with an operating handle or are interlocked and connected via a link rod to open the opening/closing plate using the operating handle. Since the conveyance path of the backflow pipe is sometimes switched to the discharge pipe side, when the amount of mixed rice supplied to the sorting section decreases just before the end of the hulling operation, it can be opened and closed simply by operating the operating handle. By opening the plate, the remaining rice can be taken out of the machine and recovered using the backflow pipe from the mixed rice tank before being supplied to the sorting section. Therefore, the side plate of the sorting section can be opened like before. The mixed rice hopper is located at a high place without any troublesome operations such as removing the remaining rice in the sorting section or removing the remaining rice stored in the closed mixed rice hopper. Even if the rice is leftover rice, there is no danger and the remaining rice can be removed safely, easily and reliably. When it is time to restart the hulling operation, the operating handle is returned to its original position, the opening/closing plate closes, and the conveyance path of the backflow pipe is switched to the mixed rice elevator side, allowing the hulling operation to be carried out smoothly. .
