In the hulling unit, a pair of hulling rolls (rubber rolls) are arranged so as to face each other, and rotate at slightly different rotational speeds. By passing the paddy between the pair of hulling rolls, the paddy is rubbed and dehulled (so-called hulling is performed). On the other hand, in the sorting section, a plurality of swinging sorting plates are arranged vertically adjacent to each other and inclined three-dimensionally. On the surface of these swing sorting plates,
An infinite number of projections having a substantially triangular cross section are formed, and the swing sorting plate swings (vibrates) left and right during the sorting process. The hulled rice (brown rice and unhulled unhulled rice) after the hulling process in the hulling unit is supplied to the oscillating sorting plate in the sorting unit, and the left and right swinging (vibration) of the oscillating sorting plate Thus, the rice is sorted into brown rice, paddy, and mixed rice in which these are mixed. Further, the brown rice selected from the hulled rice is taken out of the apparatus, the unhulled rice is returned to the hulling unit again, and the mixed rice in which both are mixed is supplied again to the swinging sorting plate. It has a configuration.

[0005] The technique of sorting rice crushed rice (oscillating sorter) using the oscillating sorting plate has already been proposed by the present applicant (Japanese Patent Publication No. 2-4349).

[0008] By the way, as shown in FIGS. 8 and 9, the sorting rice of the rice hulling sorting apparatus having such a configuration includes mixed rice (brown rice and non-hulled rice) after the hulling processing in the hulling unit. Supply plate 20 for supplying paddy) to the swing sorting plate 200

A moving sorting plate, and provided along the up-down direction, communicated with each of the swinging sorting plates via a mixed rice supply port, and the mixed rice after the degassing process is sent to each of the swinging sorting plates. A single supply gutter for supply, and the mixed rice that is communicated with the supply gutter, is located immediately above the supply gutter, is supplied with the mixed rice after degassing processing, and stores and stores a fixed amount of the mixed rice. And a hopper for sequentially supplying the mixed rice to the supply gutter, wherein the mixed rice is regulated by regulating the flow of the mixed rice immediately after being supplied from the mixed rice supply port onto the oscillating selection plate. The thick plate temporarily stored on one end of the rocking sorter plate is placed on the rocking sorter plate. The mixed rice temporarily laid on each of the rocking sorting plates in a state where a gap of a predetermined dimension is provided between the rocking plate and the surface of the rocking sorting plate is temporarily stored by the layer thick plate. The present invention is characterized in that the liquid is sequentially and evenly flowed out from the gap with the front surface to the other end side of the swing sorting plate.

In the sorting apparatus according to the first aspect of the present invention, a fixed amount of the mixed rice after the dewaxing treatment is stored in the hopper, and is further fed into the supply gutter and sequentially from the lowermost portion to the uppermost portion of the supply gutter. Will be charged. Further, a fixed amount of the mixed rice in the supply gutter is sequentially supplied to all the swing sorting plates from all the mixed rice supply ports. Immediately after being supplied from the mixed rice supply port onto the oscillating sorter, the mixed rice is temporarily stored on one end of the oscillating sorter with its flow being regulated by the thick plate,
From the gap provided between the layer thick plate and the surface of the oscillating selection plate, the liquid is sequentially and uniformly discharged to the other end of the oscillating selection plate.
In the mixed rice supplied to the swing sorting plate, brown rice is sorted from the mixed rice by swinging the swing sorting plate.

[0013] As described above, the mixed rice immediately after being supplied from the mixed rice supply port onto the oscillating sorting plate is temporarily stored in the layered slab, and between the layered slab and the surface of the oscillating sorting plate. Because it was configured to flow out to the other end side of the oscillating sorter from the gap provided at the end of the oscillating sorter, regardless of the properties of the mixed rice (rice and brown rice) and its moisture content, The layer thickness can be kept constant. Further, since a layer thick plate is provided for each of the plurality of swing sorting plates, it is possible to supply the swing sort plates evenly without variation in the layer thickness. In other words, by maintaining the amount of the mixed rice temporarily stored on one end of the oscillating sorting plate by the layer thick plate at a certain amount or more, a uniform layer is formed on all the oscillating sorting plates. Thick mixed rice can be supplied. Therefore, the sorting performance is improved as a result.

Further, the thickness of the layered plate is a simple structure that is simply provided with a gap of a predetermined size provided between the plate and the surface of the swinging separation plate, so that the cost can be reduced.

Further, since the supply gutter has a single structure, a partition plate which has been indispensable in the past is not required (in other words, the distribution gutters provided adjacent to each other as in the related art are unnecessary. ), And the structure becomes extremely simple. Therefore, the number of parts is reduced and the assemblability is improved, which can also reduce the cost.

As described above, in the sorting apparatus according to the first aspect, mixed rice can be uniformly supplied to each swinging sorting plate with a simple structure, and cost can be reduced.

According to a second aspect of the present invention, in the sorting apparatus according to the first aspect, the size of the gap between the layer thick plate and the surface of the swing sorting plate can be changed. Features.

According to the second aspect of the present invention, since the size of the gap between the layer thick plate and the surface of the swing sorting plate can be changed, the amount of the mixed rice supplied to the swing sort plate is adjusted. can do. Therefore, the sorting process can be performed with the layer thickness of the mixed rice on the swinging sorting plate in an optimum state.

Below the hopper 68, a single supply gutter 72 is provided along the vertical direction of the apparatus. As shown in FIGS. 4 to 6, the supply gutter 72 communicates with the corners of the respective swing sorting plates 74 stacked with a predetermined gap therebetween via the mixed rice supply port 85. . Thus, the single supply gutter 72 can receive the mixed rice K sent from the hopper 68, distribute the mixed rice K to each of the swinging sorting plates 74, and distribute and supply the mixed rice to each of the mixed rice supply ports 85. It has become.

Further, the mixed rice supply port 85 of the swinging sorting plate 74
Is provided with an opening adjustment plate 92. Opening adjustment plate 9
2, the opening area of the mixed rice supply port 85 can be changed,
By operating the opening adjusting plate 92, the amount of the mixed rice K supplied to the swing sorting plate 74 from the mixed rice supply port 85 can be adjusted.

The swing sorting plate 74 has one corner (FIG. 1).
(The left side and the near side) are adjusted so as to be lower than the height position of the corner on the diagonal line of the corner, and are three-dimensionally inclined. That is, in FIG. 1, the right side of the swing sorting plate 74 is high and the left side is inclined low, and
The back side of the paper is high and the front side of the paper is inclined low. On the entire surface of the swing sorting plate 74, an infinite number of projections 73 having a substantially triangular cross-section with the right side standing upright and the left side gently inclined.
Are formed by embossing. Thus, the mixed rice K distributed by the supply trough 72 falls and flows into the swing sorting plate 74 through the respective mixed rice supply ports 85.

Further, as shown in detail in FIG. 7, in the vicinity of the corner of the swing sorting plate 74, a supply auxiliary plate 76 is provided corresponding to each mixed rice supply port 85. The supply auxiliary plate 76 has a substantially triangular cross section having a right-side surface standing upright and a left-side surface gently inclined, formed continuously in a step-like (corrugated) shape. The spreading speed of the mixed rice K along is increased. Thereby, it is configured that the mixed rice K is promptly spread to the portion (rear side end) corresponding to the mixed rice supply port 85 of the swinging sorting plate 74, and the supply amount is stabilized.

Further, beside the supply auxiliary plate 76,
A thick plate 77 is provided. This thick plate 77 is formed by holding slits 79 provided on the left and right side walls of the swing sorting plate 74.
Both ends are fitted and attached, and each of the swing sorting plates 74 is provided with a gap S of a predetermined size (for example, about 8 mm) between the swing sorting plate 74 and the surface of the swing sorting plate 74. I have. The mixed rice supply port 85 is formed by this layer board 77.
The flow of the mixed rice K immediately after being supplied to the oscillating selection plate 74 from above is regulated, and the mixed rice K is temporarily stored on the rear end of the oscillating selection plate 74. . Thick plate 7
The mixed rice K temporarily stored by 7 has a uniform layer thickness sequentially from the gap S between the layer thick plate 77 and the surface of the swing sorting plate 74 toward the front side of the swing sorting plate 74. It is a configuration that flows out.

Further, the size of the gap S between the thick plate 77 and the surface of the swing sorting plate 74 can be changed by adjusting the fitting position of the thick plate 77 into the holding slit 79.

The supply gutter 72 and the oscillating sorting plate 7 having the above-described configurations are used.
4 is assembled to the main motor 12B.
0 is transmitted and operated, and the rotational driving force is converted into a reciprocating driving force by a crank mechanism (cam mechanism).
Swings (vibrates) in the left-right direction. The mixed rice K supplied on the oscillating sorting plate 74 is moved by the left and right swinging (vibration) of the oscillating sorting plate 74 to produce brown rice G and paddy M.
(Which could not be removed) and mixed rice K in which these are mixed.

That is, the brown rice G having a large specific gravity sinks below the mixed rice layer and is sequentially pushed to the right side of the swing sorting plate 74 by being pushed out by the projections 73. The water will be sequentially moved to the left side of the swing sorting plate 74 so as to float above the rice layer and slide down on the surface of the layer. Due to this difference in the degree of transition, brown rice G, mixed rice K in the central region, and paddy M in the left region on the swing sorting plate 74 are concentrated and separated (separated). It has become. This phenomenon gradually and clearly appears while naturally flowing down from the back side (supply side) of the swing sorting plate 74 to the front side. Thus, the brown rice G, the mixed rice K, and the paddy M (hereinafter, referred to as mixed rice, etc.) on the rocking sorter 74 fall downward from the near side of the rocking sorter 74 of each stage (six pieces). It has become.

Further, the falling-side end of the swing sorting plate 74 (FIG. 1)
A fixed partition plate 78 is provided at the front end of the drawing sheet).

The fixed partition plate 78 is located near the boundary between the paddy M and the mixed rice K separated (separated) by the rocking separation plate 74 as described above.
The paddy M falls on the left side, and the mixed rice K falls on the right side of FIG.

A swing discharge gutter 82 is provided below the fixed partition plate 78.
2, a rice return port 84, a mixed rice discharge port 86, and a brown rice discharge port 88 are provided. Therefore, the paddy M sorted (separated) by the fixed partition plate 78 is guided to the paddy return port 84, and falls from the paddy return port 84 to the paddy return hopper 90. Further, the paddy return hopper 90 communicates with the screw conveyor 50 of the first grain gutter 48 described above. For this reason, the rice M that has fallen into the rice return hopper 90 is
In this configuration, the first gutter 48 is guided to the screw conveyor 50. Further, here, in the screw conveyor 50 of the first grain trough 48, the paddy M falls on the screw on the near side in FIG. 1 among the two divided parts as described above. For this reason, the paddy M sorted (separated) by the fixed partition plate 78 is accumulated at the front end of the sheet of FIG. 1 by the screw conveyer 50, is repelled by the paddy return slotr 52, and again has the pair of paddy rolls 22, 24
Will be returned upstream.

Further, a switching valve 53 is provided immediately after the paddy return thrower 52 (on the way of the paddy return route) as shown in FIG. When the switching valve 53 is in the “open” state, the return path of the chaff M can be opened to the outside of the apparatus. Therefore, when the switching valve 53 is operated to be in the “open” state, the rice M returned by the rice return thrower 52 can be directly discharged to the outside of the device.

The swing discharge gutter 82 is provided with a brown rice discharge shutter 106. Brown rice discharge shutter 1
Reference numeral 06 is provided between the mixed rice discharge port 86 and the brown rice discharge port 88 to partition the discharge area of the brown rice and the mixed rice falling from the swing sorting plate 74 and change the partition position. In addition, the brown rice outlet 88 can be closed.

That is, for a predetermined time (ie, a transition period) immediately after the operation of the hulling sorting apparatus 10 is started, the sorting unit 10B
1 is not completely performed, and the mixed rice K may be present at the right end of the swing sorting plate 74 in FIG. For this reason, in the transitional period, the brown rice discharge port 88 is closed by the brown rice discharge shutter 106, and all the rice is guided to the mixed rice discharge port 86. When the transition period ends, the brown rice discharge shutter 106 is opened, and the brown rice is discharged from the brown rice discharge port 88.

Further, the brown rice discharging shutter 106
When the brown rice discharge port 88 is opened, the discharge region of the brown rice G and the mixed rice K falling from the swing sorting plate 74 can be partitioned. For this reason, the brown rice G guided by the brown rice discharge shutter 106 is supplied to the brown rice discharge port 88.
The mixed rice K falls into the mixed rice discharge port 86. The position of the open degree of the brown rice discharge shutter 106 is determined by the degree of selection at the time of brown rice selection by swinging of the swing sorting plate 74. That is, depending on the type of rice and the surrounding environment, there are cases where sorting is easy and difficult, and when sorting is easy, the area where the brown rice G is dropped is widened, so that the brown rice discharging shutter 106 is set to the left in FIG. Rotate to. On the other hand, when sorting is difficult, the area where the brown rice G falls is narrowed, and the brown rice discharging shutter 1 is accordingly reduced.
Rotate 06 to the right in FIG.

Further, a plurality of rectifying fins 102 are provided in the vicinity of the end on the near side in FIG. 1 in the falling channel that falls from just before the swing sorting plate 74. For this reason, the brown rice G and the mixed rice K sorted and dropped on the swing sorting plate 74 are guided to the partition position by the brown rice discharge shutter 106 by the rectifying fins 102. Therefore, even if the swing sorting plate 74 swings, the brown rice G and the mixed rice K do not scatter (are not mixed), and fall accurately to the partition position by the brown rice discharge shutter 106.

The swing sorting plate 74A located at the uppermost stage
At the end on the falling side (the end on the near side of the sheet of FIG. 1), near the both ends in the width direction of the swing sorting plate 74A (near the left and right ends in FIG. 1), a drop confirmation (such as mixed rice) is used. A pair of rotating fins 96, 98 (as layer thickness sensors) are each provided. Therefore, when the mixed rice or the like falls from the swing sorting plate 74, the mixed rice or the like engages with the rotating fins 96, 98, and the rotating fins 96, 98 can be rotated.

A permanent magnet is embedded in the rotary fins 96 and 98, and a proximity switch is provided along a part of the rotation trajectory. For this reason, the rotating fins 96, 9
When 8 rotates, the proximity switch repeats on / off to output a pulse signal. Thereby, it is confirmed that the mixed rice and the like on the swing sorting plate 74 are uniformly diffused by the rotation of both the rotating fins 96 and 98 at the same rotation speed (the layer thickness of the mixed rice and the like is uniform). Can be recognized.

A discharge gutter 100 is disposed below the sorting unit 10B, that is, at a position facing the mixed rice discharge port 86 and the brown rice discharge port 88 described above. This discharge gutter 100
Is inclined downward in the left and right direction of the apparatus with a middle portion between the mixed rice discharge port 86 and the brown rice discharge port 88 as a boundary. Thus, the mixed rice K discharged from the mixed rice discharge port 86 is conveyed leftward in FIG. 1 by the left inclined surface of the discharge gutter 100, and the screw conveyor 50 (FIG. (The back side of the paper). As a result, the mixed rice K is again mixed with the mixed rice tank 5 by the mixed rice elevator 54.
6 and the sorting by the sorting unit 10B is performed again.

On the other hand, the brown rice G discharged from the brown rice discharge port 88 is conveyed rightward in FIG. 1 by the right inclined surface of the discharge gutter 100.

At the end of the inclined surface on the right side of the discharge gutter 100, a brown rice discharge lower 108 is integrally provided. Therefore, the discharge gutter 10 discharged from the brown rice discharge port 88
The brown rice G conveyed by the inclined surface on the right side of FIG.
0 is taken out to the outside.

A lid 114 is provided at the opening of the brown rice extraction gutter 110. The lid 114 can be held in either the closed state or the open state, and is pressed by the discharging force of the brown rice G to discharge the brown rice G even in the closed state. Therefore, if the lid 114 is closed, it is possible to prevent invasion of small animals (rats and the like) from the outside that feed on brown rice G.

Next, the operation of the present embodiment will be described.

The mixed rice K thus discharged is discharged from the mixed rice discharge port 86, and is conveyed to the screw conveyor 50 of the first grain trough 48 by the left inclined surface of the discharge trough 100. As a result, the mixed rice K is again sent to the mixed rice tank 56 by the mixed rice elevator 54, and the sorting is performed again in the sorting unit 10B.

On the other hand, the brown rice G sorted (separated) by the brown rice discharge shutter 106 is discharged from the brown rice discharge port 88, and is conveyed to the brown rice discharge lower 108 by the inclined surface on the right side of the discharge gutter 100. Slower 108
And is taken out of the brown rice extraction gutter 110 to the outside.

Here, in the hulling sorter 10 (sorter 10B as a sorter), the supply gutter 72 for supplying the mixed rice K after the dehulling treatment to each swinging sorter plate 74 is provided. However, since it is merely a single structure having the mixed rice supply port 85, a partition plate which has been indispensable in the past is unnecessary (in other words, the distribution gutters provided adjacent to each other as in the related art are not provided). Is unnecessary), and the structure becomes extremely simple. Therefore, the number of parts is reduced and the assemblability is improved,
Cost can be reduced.

Further, in the hulling sorter 10 (sorting unit 10B as a sorter), the rice is separated from the supply gutter 72 by being communicated with the supply gutter 72, and the mixed rice K after the dedusting process is fixed. Since the hopper 68 for sequentially supplying the mixed rice K stored and supplied to the supply gutter 72 is provided, the mixed rice K in the supply gutter 72 is sequentially supplied from all the mixed rice supply ports 85 to the respective swing sorting plates 74. A certain amount can be supplied. In other words, by storing a fixed amount of the mixed rice K in the hopper 68, it is possible to supply the uniform mixed rice K to all the rocking sorting plates 74 through all the mixed rice supply ports 85. it can.

Further, in the hulling sorting apparatus 10 (sorting section 10B as a sorting apparatus), the mixed rice K immediately after being supplied onto the oscillating selection plate 74 from the mixed rice supply port 85 is mixed with the thick plate 7
7, and temporarily flows out from the gap S provided between the thick plate 77 and the surface of the swing sorting plate 74 to the front side of the swing sorting plate 74. The layer thickness of the mixed rice K on the oscillating sorting plate 74 can be kept constant irrespective of the properties of K and its moisture content. Further, since the layer thick plate 77 is provided for each of the plurality of swing sorting plates 74, the layer thickness of each swing sorting plate 74 can be supplied evenly without variation. In other words, by maintaining the amount of the mixed rice K temporarily stored on the rear end of the rocking sorting plate 74 by the layered plate 77 at a certain amount or more, all rocking The mixed rice K can be supplied to the sorting plate 74 with a uniform layer thickness. Therefore, the sorting performance is improved as a result.

The thick plate 77 is simply a swing sorting plate 74.
Since it has a simple configuration in which a gap S of a predetermined size is provided between the surface and the surface, cost can be reduced.

As described above, in the hulling sorting apparatus 10 (sorting section 10B as a sorting apparatus) according to the present embodiment, the mixed rice K having a uniform thickness is formed on each swing sorting plate 74 by a simple structure.
Can be supplied, and cost can be reduced.

Further, in the hulling sorter 10 (sorting unit 10B as a sorter), the size of the gap S between the thick plate 77 and the surface of the swing sorting plate 74 can be changed. The amount and layer thickness of the mixed rice K supplied to the dynamic sorting plate 74 can be adjusted. Therefore, the sorting process can be performed with the layer thickness of the mixed rice K on the swing sorting plate 74 in an optimum state.
