Description

[Detailed Description of the Invention] The present invention relates to an automatic processing device for mixed rice and brown rice in a rice hulling and sorting device.

Conventionally, a rice hulling device has been equipped with either a lightweight sieve-type mangoku or a heavy-duty swing-type grain sorting device as a device for separating mixed rice.

The present invention relates to a rice hulling and sorting device using the latter oscillating grain sorting device.

In the latter type of oscillating grain sorting device, as is well known, the brown rice taken out from the brown rice take-out port of the sorting device is taken out of the system, and the mixed rice taken out from the take-out port is placed at the bottom of the elevator. The structure is such that the unhulled rice taken out from the unhulled rice outlet is connected to the supply hopper of the hulling device, and the unhulled rice and mixed rice can be recycled. There was a problem that scrap rice was mixed into the mixed grains and the brown rice taken out from the brown rice outlet.

That is, since waste rice has slightly different specific gravities, in the separation operation using the specific gravity sorting device, a large amount of rice waste is distributed in a certain specific portion on the sorting plate and does not move from that spot. Therefore, as the amount of waste rice increases, the separation work of mixed rice will gradually be affected. Conventionally, this was done by simply guiding the finished rice to another rotary waste rice sorting device and removing it after the work was completed, and the sorting plate of the above-mentioned gravity sorting device was used to remove the finished rice. As for the accumulation of waste rice on top, there was no plan at all.

Accordingly, the present invention has been devised by providing a swing type grain sorting device 10 in the vicinity of the hulling device 1, and the mixed rice discharged from the hulling device 1 is supplied to the grain sorting device 10 by an elevator 11. The structure is such that the unhulled rice is separated into unhulled rice, brown rice, and mixed rice, and the unhulled rice is returned to the hulling device 1 through the unhulled rice return trough 27, etc., and the brown rice is guided out of the system through the receiving trough 32, and the unhulled rice is returned to the hulling device 1 through the unhulled rice return trough 27. In a device configured such that rice is returned to the grain sorting device 10 via an inclined flow plate 30, an elevator 11, etc., both the receiving trough 32 and the inclined flow plate 30 have porous holes capable of sieving out waste rice. This is an automatic processing device for mixed rice and brown rice in a paddy rice sorting device, which is constructed of a plate or a wire mesh, and is installed in a substantially square shape on the top of the waste rice collection chamber 34. This is to prevent waste rice from accumulating in the brown rice, and to reduce the amount of waste rice in the brown rice as much as possible.

To explain this with reference to the drawings, reference numeral 1 indicates a rubber roll type hulling device, in which a pair of hulling rolls 3, 3 are mounted in an upper position below a supply hopper 2.
A suction air passage 4 is formed at the lower part of the hulling rolls 3, 3, and the lower wall of the suction air passage 4 is used as a gutter 5.
A conveyor 6 is installed horizontally on top. 7 is the suction air path 4
It is a suction windmill that sucks the inside. A case 8 that also serves as a platform is adjacent to the hulling device 1, and a swinging device that moves up and down diagonally is installed on the case 8 that also serves as a platform.
An oscillating grain sorting device 10 having a distribution gutter 9 is attached to the top of the device. Reference numeral 11 denotes an elevator installed at a lateral position near the hulling device 1, and is connected to the conveyor 6.
The grain that has been transported across is received at the bottom and raised. 12 is a storage tank. The storage tank 12
is attached to the discharge end 14 of the discharge gutter 13 of the elevator 11 by parallel links 15, 15', and is suspended by a spring 16. The upper end of the spring 16 is connected to the side of the discharge gutter 13, and the lower end is connected to the side of the storage tank 12. 17 is the storage tank 12
It is an outlet for The rocking grain sorting device 10
has a configuration as shown in FIG.
9 is higher than the swinging side 20, and the supply side 21 is higher than the discharge side 2.
2 and slopes in two directions. The distribution gutter 9 is installed at the intersection of the supply side 21 and the swinging side 19. A plurality of partition plates 23 are attached to the discharge side 22 in the width direction, and the part partitioned by the partition plates 23 near the shaking side 19 is used as the brown rice outlet 24, and the part near the shaking side 20 is used as the unhulled rice outlet. A mixed rice outlet 26 is formed between the outlet 25 and the middle thereof. A return gutter 27 is provided so that the unhulled rice that has fallen from the unhulled rice outlet 25 returns to the supply hopper 2 of the hulling device 1, and is flowed down to the upper end of the fried grain thrower 28 provided at the lower part of the return gutter 27. is opened on the supply hopper 2. The upper end 29 of the mixed rice return path is opened at the lower part of the mixed rice outlet 26. The return path is formed by an inclined flow plate 30, the lower end of which is connected to the conveyor 6. The inclined flow plate 30 is formed of a net or a perforated plate, and sieves waste rice. A switching valve 31 is installed between the upper end of the return gutter 27 and the upper end 29 of the return path. When the switching valve 31 is switched to one side, the upper part of the inclined flow plate 30 is closed and the mixed rice flows toward the return gutter 27, and when switched to the other side, the mixed rice is flowed toward the inclined flow plate 30. An upper end 33 of a brown rice receiving trough 32 opens at the bottom of the brown rice outlet 24. The brown rice receiving trough 32 is inclined toward the opposite side from the inclined flow plate 30, and is formed in a V-shape with the inclined flow plate 30. The brown rice receiving channel 32
It is also formed by a perforated plate or net that sieves waste rice. The lower part of the inclined flow plate 30 and the brown rice receiving trough 32 is formed into a waste rice collection chamber 34. 35 is an opening/closing door attached to the waste rice outlet. The brown rice flowing on the brown rice receiving trough 32 is fried by a grain lifting machine 36, and the brown rice is supplied to the next working machine.

Next, we will discuss the effect.

The present invention has the above-described structure, and when the raw material unhulled rice is supplied to the supply hopper 2, the unhulled rice is hulled when it passes between the hulling rolls 3, and becomes three parts: rice husk and unhulled unhulled rice. The light rice husks reach the suction air path 4, where they are sucked and scattered far away by the suction windmill 7. The mixed rice is guided to the lower part of the elevator 11 by the conveyor 6, ascends inside the elevator 11, and is stored in the storage tank 12 through the discharge gutter 13.
2 to the distribution gutter 9 and onto the sorting plates 18 at each stage.

Since the sorting plate 18 is oscillated by the oscillating device in the direction of the arrow W, the brown rice with a heavy specific gravity in the mixed rice is stirred up and distributed on the oscillating side 19, and the brown rice is distributed at the oscillating side 19.
The brown rice falls down, flows over the brown rice receiving trough 32, and the waste rice contained in the brown rice is sieved and stored in the waste rice collection chamber 34.

The unhulled rice with a light specific gravity is distributed in the direction of the shaking side 20, falls from the unhulled rice outlet 25, is returned to the supply hopper 2 via the return gutter 27 and the grain thrower 28, and is hulled again. In this case, the switching valve 31 is switched to the position indicated by the solid line in each figure.

The mixed rice flowing out from the mixed rice take-out port 26 flows through the inclined flow plate 30 from the shaped end 29, joins the conveyor 6, flows into the storage tank 12 by the elevator 11, and passes through the distribution gutter 9 from the discharge port 17. It circulates over the sorting plates 18, 18, . . . in each stage and undergoes sorting again. Although the inclined flow plate 30 does not allow good grains to pass through,
Since the waste rice is constituted by a perforated plate or a mesh through which the waste rice passes, the waste rice is sieved and collected in the waste rice collecting chamber 34. The waste rice collected in the waste rice collection chamber 34 can be easily taken out by opening the door 35. In this way, the mixed rice is transferred to the inclined flow plate 3.
Every time the waste rice flows over the 0, the waste rice is sieved by the perforated plate or net that it passes through, so there is no possibility that waste rice will gradually accumulate on the sorting plate 18 and deteriorate the sorting.

However, when approaching the end of the work, the switching valve 31 is switched to the position indicated by the temporary line, and the inclined flow plate 30
Since the upper end 29 is closed, the mixed rice flows into the return gutter 27 and is returned to the supply hopper 2 via the grain thrower 28, where the remaining unhulled rice is hulled along with some brown rice.

The present invention has the above-mentioned configuration and operation, and a swing type grain sorting device 10 is provided in the vicinity of the hulling device 1, and when the grains are discharged from the hulling device 1, the grains are supplied to the grain sorting device 10 by the elevator 11. The rice is separated into unhulled rice, brown rice, and mixed rice, and the unhulled rice is configured to return to the hulling device 1 through the unhulled rice return trough 27, etc., and the brown rice is guided out of the system through the receiving trough 32, In the structure in which the mixed rice is returned to the grain sorting device 10 via the inclined flow plate 30, the elevator 11, etc., the receiving trough 32 and the inclined flow plate 30 both screen out waste rice. Since the automatic processing device for mixed rice and brown rice in the hulling sorting device is constructed of a perforated plate or a wire mesh and is installed in a substantially V-shape above the waste rice collection chamber 34, However, in the present invention, waste rice is sieved every time the mixed rice flows over the inclined flow plate 30, so that the rice waste is gradually accumulated on the sorting plate, resulting in poor sorting. Waste rice is not deposited on the top surface of the plate 18, and therefore,
The sorting effect of the grain sorting device 10 is not hindered.

(b) When the brown rice flows through the brown rice receiving trough 32, waste rice in the brown rice is removed, so that the quality of the finished rice is even higher.

C. The inclined flow plate 30 and the brown rice receiving trough 32 are in the waste rice collection room 3.
Since it is attached to the top of 4 in a V-shape, the structure is not only simple. Since both are close together, cleaning is easy.

(D) Since the waste rice collection chamber 34 is based on the configuration of (C) above, one room is enough for the waste rice collection chamber 34.

etc.
