BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a side-by-side hulling device for a rocking / sorting device.

[0002]

2. Description of the Related Art Conventionally, there is a hulling section provided with a supply hopper for directly supplying grains from a grain bag and an oscillating sorting section for sorting hulled grains provided on the side of the hulling section. In this case, the hulling portion is formed by a fixed roll and a moving roll that are provided horizontally on the left and right, and a suction fan for lightweight foreign matter is a swing sorting device side by side hulling device that is arranged below the fixed roll and the moving roll. Devices are known. Also, a hulling section provided with a supply hopper for directly supplying grains from a grain bag,
A swing type sorting unit for sorting hulled grains provided on the side of the hulling unit, wherein the hulling unit comprises a tilted fixed upper roll at a slanting upper position and a slanting lower moving roll at a slanting lower position. The tilting roll type is based on, and the tilting moving lower roll is located farther than the rocking type sorting unit, the tilted fixed upper roll is placed near the rocking type sorting unit, and the suction fan for lightweight foreign matter is positioned below the swinging type sorting unit. The rocking / sorting device side-by-side hulling device arranged at is also known.

[0003]

In the former case, the hulling portion is formed by a fixed roll and a movable roll which are horizontally provided at the left and right, and a suction fan for lightweight foreign matters is arranged below the fixed roll and the movable roll. Since it has a structure, since it is not possible to select the wind unless the vertical distance between the fixed roll and the movable roll and the suction fan is considerably large, there is a problem that the height of the hulling section becomes high. In addition, the former hulling by the fixed roll and the moving roll provided horizontally on the left and right has a problem that the wear of the roll is severe. Further, the latter, the hulling device, is an inclined roll type with an inclined fixed upper roll in the oblique upper position and an inclined lower moving roll in the oblique lower position, so the roll wear is less compared to the former, but suction of light foreign matter Since the fan is arranged below the swing-type sorting unit, the height of the swing sorting device becomes large, and the size of the entire device becomes large, resulting in high cost.

[0004]

Therefore, according to the present invention, the grain hull portion 1 provided with the grain hull rice supply hopper 3 for directly feeding grains from the grain bag and the paddy provided on the side portion of the grain hull portion 1 are provided. In the one comprising an oscillating type sorting section 2 for sorting grain, the hulling section 1 is of an inclined roll type with an inclined fixed upper roll 9 at an obliquely upper position and an inclined lower moving roll 10 at an obliquely lower position, In addition, the tilt-moving lower roll 10 is arranged near the swing-type sorting unit 2, the tilt-fixing upper roll 9 is arranged farther than the swing-type sorting unit 2, and the lightweight foreign matter suction fan 16 is farther from the swing-type sorting unit 2. The horizontal sorting type hulling device is provided at the lower position of the swing sorting device.

[0005]

An embodiment of the present invention will be described with reference to the drawings.
Reference numeral 1 is a hulling section, 2 is a swinging sorting section, and a swinging sorting section 2 is provided on a side portion of the hulling section 1. The hulling section 1 and the swing-type sorting section 2 are formed separately, and are combined and combined. Reference numeral 3 denotes a paddy rice supply hopper of the paddy hull portion 1, which is provided on the upper part of the paddy rice paddle 1 and is fed into the paddy rice feed hopper 3 with a grain bag. Reference numeral 4 denotes a bottom wall of the paddy rice supply hopper 3, a supply port 5 is formed in a part of the bottom wall 4, and the feeding roll 6 is provided in the supply port 5.
And a supply opening / closing valve 7 are provided. The supply opening / closing valve 7 has a structure in which a tip opens and closes vertically around a shaft 8 at one end.

Below the feeding roll 6, a pair of inclined rolls are axially mounted. Reference numeral 9 is an inclined fixed upper roll, and 10 is an inclined downward movement roll. The inclined fixed upper roll 9 is rotatably and freely mounted on the case of the hulling portion 1 by a shaft 11. The inclined lower moving roll 10 has an angle of about 45 °,
It is located diagonally below and is locked by the shaft 12. The tilted lower moving roll 10 is elastically attached to the tilted fixed upper roll 9 and is configured so that it can be moved forward and backward. Reference numeral 13 is an adjusting bolt that adjusts the lower tilt moving roll 10. When the adjusting bolt 13 is rotated, the lower tilt moving roll 10 reciprocates.

The tilt-fixed upper roll 9 and the tilt-lower movable roll 10 are arranged so that the tilt-lower movable roll 10 is closer to the rocking type sorting section 2. Therefore, the hulled material by the tilted fixed upper roll 9 and the tilted lower moving roll 10 is discharged in a direction farther from the rocking type sorting unit 2. The first conveyer 14 and the second conveyer 15 are axially mounted at the lower positions of the inclined fixed upper roll 9 and the inclined lower moving roll 10, but the suction fan 16 is provided on the side farther from the swing type sorting unit 2. That is, the tilted fixed upper roll 9 and the tilted lower moving roll 10 are opposite to those of the present invention, and the tilted fixed upper roll 9 is closer to the swing type sorting unit 2 and the tilt lower moving roll 10 is swing type sorting. If it is arranged farther from the section 2, the hulled materials are inevitably discharged in the direction of approaching the swing-type sorting section 2, so that the suction fan 16 is located below the swing-type sorting section 2 and swing-type sorting is performed. Although it becomes necessary to provide the portion 2 at a high level, in the present invention,
Since the suction fan 16 is provided in the direction farther from the swing type sorting unit 2, it is possible to prevent a defect that makes the swing type sorting unit 2 tall.

An elevator 1 for raising mixed rice is provided on the side of the huller 1.
7 is provided, and a storage tank 18 is attached to the discharge part of the elevator 17 for raising the mixed rice. The storage tank 18 is provided with an opening / closing valve 19 that rotates up and down according to the storage amount of the mixed rice, and a control valve 20 that adjusts the supply port size. Reference numeral 21 is a rack provided on the control valve 20 side, and 22 is a pinion that engages with the rack 21. A distributor 23 and a plurality of stages of sorting plates 24 are provided below the storage tank 18. Sorting plate 24
Is horizontally swung by the horizontal swing mechanism 25.

The sorting plate 24 has a supply side 26 and a discharge side 27.
It has a rectangular shape composed of a swaying side 28 and a non-swaying side 29, and a supply port 30 is opened at the swaying side 28 of the supply side 26, and the plate surface is oriented toward the swaying side 28. A protrusion 31 is provided which is raised on the side 28. Although the projections 31 are shown to be considerably large in FIG. 4, they are actually very small and are formed innumerably on the entire plate surface. The protrusion 31 is on the rocking side 2
Although 8 is high, it is also suitable for the discharge side 27, and it is expected that the grain flowing from the supply port 30 will be swept toward the discharge side 27. The sorting plate 24 is formed such that the discharge side 27 is lower than the supply side 26, and the swing side 28 is slightly higher than the non-sweep side 29. However, when the adjustment handle 32 is rotated, the swing side 28 and the non-sweep side are not moved. The height of the side 29 is adapted to be adjusted. Although the detailed structure of the adjusting mechanism is omitted in the drawing, it is possible to apply a known technique.

The discharge side 27 is lower than the supply side 26 in order to allow the grain supplied from the supply port 30 to be discharged to the discharge side 27, but it seems that the gradient should not be too steep. is there. If the slope is too steep, the inlet 30
This is because the grain that has flowed in more quickly flows along the wall of the swaying side 28 to the discharge side 27, and the grain does not come to the portion A in the figure and becomes blank, creating a useless space. Therefore, if the gradient is made gentle and the flow of the grain toward the discharge side 27 is deteriorated, the grain is distributed even to the portion A, and the grain can be efficiently sorted. The sorting plate 24 is axially supported on the frame side of the swing-type sorting unit 2 via a swing support column 33.
When 4 rotates, it oscillates in the left-right direction, but the left-right oscillation at this time is configured to horizontally oscillate in a direction that is farther from or closer to the hull portion 1. Since the lower end of the swing column 33 is axially fixed to the frame side, the movement of the sorting plate 24 at the upper end is an arc even if it is horizontal, but the actual amplitude is about 50 mm, so it is visually apparent. Is a horizontal swing.

When the sorting plate 24 swings horizontally, the supply port 30
By the action of the protrusions 31, the grains thus supplied spread over the entire surface of the selection plate 24, and spread toward the non-swing side 29 and separated. 35 is a brown rice outlet, 36 is a mixed rice outlet, 37 is a paddy rice outlet, 38 is an adjusting partition plate, 39 is a finished rice outlet gutter, 4
0 is a mixed rice extraction gutter, 41 is a paddy rice extraction gutter, and the finished rice extraction gutter 39 is brought into contact with a grain bag to take out the finished rice.
Calls Return Thrower 42. The return thrower 42 communicates with the paddy rice supply hopper 3. 43 is a motor.

[0012]

[Operation] Next, the operation will be described. (Overall operation) When the grain bag is carried and lifted, the bag mouth is placed on the paddy rice supply hopper 3 and the bottom is lifted and supplied (stretched), the grain is taken in from the gap at the open end of the supply port 5. It drops onto the roll 6, is supplied by the rotation of the feeding roll 6, and is hulled between the inclined fixed upper roll 9 and the inclined lower moving roll 10 to peel off the chaff. All the rice hulls flow together as shown by the white arrows, the grains with a high specific gravity fall to the first conveyor 14 without being affected by the wind, and the light unripe rice is carried by the wind to the second conveyor 15 Dropped onto the second conveyor 1
It is taken out of the machine by the rotation of 5. Further, the lightweight rice husk is sucked by the rotation of the suction fan 16 and discharged to a distant place. The heavy mixed grain dropped on the first conveyor 14 is lifted 17
After flowing into the lower part of the tank, it rises, is stored in the storage tank 18, and is supplied from the storage tank 18 to the distribution device 23.
Since the distribution device 23 is horizontally oscillated by the horizontal oscillating mechanism 25 together with the selection plate 24, the distribution device 23 distributes and supplies it to the selection plates 24 of each stage (upper and lower three stages in the figure) and from each supply port 30. It is supplied to each of the sorting plates 24 and subjected to swing sorting. The selected finished rice is taken out from the finished rice take-out gutter 39 of the brown rice take-out port 35 and stored in the grain bag, and the mixed rice is returned to the first conveyor 14 through the mixed-rice take-out gutter 40 of the mixed-rice take-out port 36. The paddy rice flows from the paddy rice take-out port 37 through the non-paddy rice take-out non-41 into the return thrower 42, and the return thrower 42
Is returned to the supply hopper 3 for reprocessing.

(In particular, the function of the hulling portion 1) The tilt-fixing upper roll 9 and the tilt-lower moving roll 10 of the present invention are the swing-type sorting unit 2
The tilted fixed upper roll 9 at a farther position is higher, and the tilted lower moving roll 10 closer to the swing type sorting unit 2 is lower. Therefore, since the hulled matter is discharged in a direction farther from the rocking type sorting unit 2, a suction fan 16 for wind sorting for sorting the hulled matter is selected.
Has a structure in which it is mounted at the farthest position from the swing type sorting section 2. Therefore, both the sorting plate 24 and the horizontal swinging mechanism 25 of the swing-type sorting unit 2 can be provided independently of the suction fan 16, so that the sorting plate 24 can be provided at a low position, and the entire size can be reduced. -The effect that it can be formed at low cost is achieved. Contrary to the above, the tilted fixed upper roll 9 and the tilted lower moving roll 10 have a higher tilted lower moving roll 10 closer to the rocking type sorting unit 2 and a tilted fixed upper roll 9 farther from the rocking type sorting unit 2. When the height is set low, the attachment position of the suction fan 16 is located below the selection plate 24.
Can not be set low.

(In particular, the function of the selection plate 24) The projection 31 formed on the plate surface of the selection plate 24 is different from the conventional one and is directed toward the swaying side 28, but also toward the discharge side 27. Are provided. Therefore, the grain that has flowed in through the supply port 30 is caused to flow toward the discharge side 27 not only by the gradient of the sorting plate 24 but also by the pushing action of the protrusions 31, so that even if the gradient of the sorting plate 24 is loosened, the grain will be considerable. You can select efficiently at speed. Moreover, since the slope is gentle, no blank portion is formed in the portion A. Further, since the sorting plate 24 is horizontally oscillated, there is no vertical amplitude, and there is no so-called "poor shaking" unpleasant vibration.

[0015]

According to the former of the known examples, the hulling portion is formed by a fixed roll and a movable roll which are horizontally provided, and a suction fan for lightweight foreign matters is arranged below the fixed roll and the movable roll. Since it has a structure, since it is not possible to select the wind unless the vertical distance between the fixed roll and the movable roll and the suction fan is considerably large, there is a problem that the height of the hulling section becomes high. In addition, the former hulling by the left and right horizontal fixed rolls and the moving rolls has a problem that the wear of the rolls is severe. Further, the latter, the hulling device, is an inclined roll type with an inclined fixed upper roll in the oblique upper position and an inclined lower moving roll in the oblique lower position, so the roll wear is less compared to the former, but suction of light foreign matter Since the fan is arranged below the swing-type sorting unit, the height of the swing sorting device becomes large, and the size of the entire device becomes large, resulting in high cost.

However, according to the present invention, the hulling section 1 provided with the hulled rice supply hopper 3 for supplying grains directly from the grain bag is provided at the upper portion.
And a rocking type sorting section 2 for sorting hulled grains provided on the side of the hulling section 1, the hulling section 1 being provided.
Is an inclined roll type with an inclined fixed upper roll 9 in an oblique upper position and an inclined lower moving roll 10 in an oblique lower position, and
The tilt-moving lower roll 10 is arranged near the swing-type sorting unit 2, the tilt-fixing upper roll 9 is arranged farther than the swing-type sorting unit 2, and the lightweight foreign matter suction fan 16 is located below the swing-type sorting unit 2. Since the swing sorting device is a side-by-side hulling device arranged at a position, since the hulled matter has a structure that is discharged in a direction farther than the swinging sorting part 2, a wind sorting for sorting this The suction fan 16 can be installed at a position farthest from the swing type sorting unit 2, and since the position thereof is unrelated to the sorting plate 24 and the horizontal swing mechanism 25 of the swing type sorting unit 2, the sorting plate 24 Can be installed at a low position,
The effect that the whole can be formed small and inexpensive.
