DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a distribution gutter structure of a hulling apparatus for removing a supplied paddy and removing it as brown rice.

[0002]

2. Description of the Related Art There is known a hulling apparatus for removing brown rice by subjecting supplied rice to dehulling processing.
-28882).

[0003] In such a hulling apparatus, a hulling unit for dehulling the supplied paddy, and hulled rice after dehulling in the hulling unit (brown rice and unhulled rice). And a sorting unit for sorting and extracting brown rice from the rice.

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).

[0006] By the way, to the sorting section of the hulling apparatus having such a configuration, mixed rice (brown rice and unhulled unhulled rice) that has been subjected to dehulling processing in the hulling unit is supplied to a rocking sorting plate. Supply and distribution gutters are provided. The distribution gutters are provided adjacent to each other in accordance with the number of swing sorting plates at the end portion of the feed gutter in the mixing rice feeding direction, and furthermore, each of the swing sorting plates is independently provided via a communication inlet. Communication. The communication inlets of the distribution trough are provided corresponding to the respective corners of the oscillating sorting plate, so that the communication inlets are vertically adjacent to each other.

[0007] The mixed rice that has been subjected to the dewatering process is sequentially fed to the swing sorting plate by the supply gutter, and the mixed rice sent from the supply gutter is received by the distribution gutter, and each rocking sorter plate. It is configured to be distributed every time and supplied from each communication input port.

However, if the number of swing sorting plates is increased in order to improve the sorting ability of such swing sorting plates, the number of distribution gutters (communication inlets) must naturally be increased. However, there is a limit to increasing the number, limited by the overall size of the device. In particular, since the distribution gutters are provided adjacent to each other, the distribution gutter corresponding to the topmost swing sorting plate among the distribution gutters has a communication input port with the swing sorting plate located adjacent to the distribution gutter. The distribution of the mixed rice to the uppermost swinging sorting plate becomes insufficient as a result of being restricted (obstructed) by the other distribution gutters, which makes it impossible to provide this large enough. (The supply amount of mixed rice is reduced as compared with the swing sorter.)

[0009]

In view of the above facts, the present invention sufficiently supplies mixed rice to the uppermost rocking sorter plate and supplies mixed rice as compared with other rocker sorters. It is an object to obtain a distribution gutter structure of a hulling device in which the amount does not decrease.

[0010]

The distribution gutter structure of the hulling device according to the first aspect of the present invention is provided in plural vertically adjacent to each other.
An oscillating plate for selecting brown rice from mixed rice in which paddy and brown rice are mixed by oscillating, a supply gutter for sequentially feeding the mixed rice to the oscillating sorting plate after dewatering, and The end of the gutter in the mixing rice feeding direction is provided adjacent to each other according to the number of the swing sorting plates, and is independently communicated with the plurality of swing sorting plates via a communication input port. A distribution gutter for a hulling apparatus, comprising: a distribution gutter for receiving mixed rice fed from a gutter, distributing the mixed rice to each of the rocking sorting plates, and supplying the mixed rice to each of the communication input ports. The mixed rice from the supply gutter is supplied to the distribution gutter corresponding to the uppermost rocking separation plate, separately from the inlet for communication with the rocking separation plate. A drop port is provided for direct dropping to the sorting plate. It is characterized in that.

According to the first aspect of the present invention, the mixed rice after the dehulling treatment is sequentially fed to the swing sorting plate by the supply gutter, and the mixed rice sent from the supply gutter is received by the distribution gutter. It is distributed to each swing sorting plate and supplied to each through the communication inlet. In the mixed rice supplied to the swing sorting plate, brown rice is sorted from the mixed rice by swinging the swing sorting plate.

[0012] Here, the distribution gutter corresponding to the uppermost swing sorter plate among the distribution gutters receives the mixed rice from the supply gutter at the uppermost position separately from the inlet for communicating with the swing sorter plate. Is provided with a drop port for directly supplying a drop to the rocking sorter plate located at the uppermost position, and the mixed rice is supplied to the rocking sorter plate located at the uppermost position not only from the communication input port but also from the dropping port.

[0013] Therefore, since the distribution gutters are provided adjacent to each other, the communication opening of the distribution gutter corresponding to the topmost swing selection plate among the distribution gutters and the swing selection plate is provided.
Even if it cannot be provided sufficiently large because it is restricted (obstructed) by the other distribution trough located next to it, as a result, the supply amount of mixed rice to the uppermost rocking sorter plate is not sufficient. It will not be sufficient (the supply of mixed rice will not decrease compared to other rocking sorters).

As described above, according to the distribution gutter structure of the hulling device of the first aspect, when the number of distribution gutters (communication input ports) provided adjacent to each other is increased, the distribution gutter has the highest rank. Even if it is not possible to provide a large enough communication inlet for the distribution gutter corresponding to the rocking sorting plate located at the top of the rocking sorting plate, the mixed rice can be sufficiently supplied to the top rocking sorting plate. It can be supplied, and the supply amount of mixed rice does not decrease as compared with other rocking sorting plates.

At the most downstream end (right end in FIG. 1) of the supply gutter 68, a plurality of distribution gutters 72 are provided along the front-rear direction of the apparatus (from the near side to the far side in FIG. 1). .
As shown in FIGS. 5 and 6, these distribution gutters 72 are provided adjacent to each other, and each swing selection plate 74 is stacked below the supply gutter 68 with a predetermined gap therebetween.
Are independently communicated with each other via a communication input port 85. Thus, the mixed rice K sent from the supply gutter 68 can be received, distributed to each swing sorting plate 74, and distributed and supplied to each of the communication input ports 85.

Here, of each distribution gutter 72, distribution gutter 72A corresponding to rocking sorting plate 74A positioned at the highest position.
In addition to the communication input port 85A for communicating with the swing sorting plate 74A, a drop port 87 capable of directly supplying the mixed rice from the supply gutter 68 to the swing sorting plate 74A located at the highest position is provided. I have. Therefore, in the swing sorting plate 74A located at the highest position, the mixed rice K is supplied not only from the communication input port 85A but also from the drop port 87.

The swing sorting plate 74 has one corner (FIG. 1).
(The right side and the back side of the fulcrum) as a fulcrum, the height of the corner on the diagonal of the corner is adjusted to be lower than the corner of the fulcrum, and the corner is 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 low and inclined. And, on the entire surface of the swing sorting plate 74,
An infinite number of projections 73 having a substantially triangular cross section with a right side standing and a left side gently inclined are formed by embossing.
Thus, the mixed rice K distributed by the distribution trough 72 (72A) falls through the communication input ports 85 (85A) near the corners, which are the fulcrums.

Further, in the vicinity of the corner of the swing sorting plate 74, each communication inlet 85 (85) of the distribution gutter 72 (72A) is provided.

Are provided along the front-rear direction of the frame body 11, respectively, and hold both ends of the swing sorting plate 74 in the width direction. In this case, the rear side of the device of the frame 11 is open, so that the swing sorting plate 74 can be inserted and removed along the guide rail 75 from the rear side of the device of the frame 11.

The rear end of the frame 11 is provided with a back cover 7.
7 are provided. The back cover 77 is provided on each swing sorting plate 7.
4 is fixed by mounting screws 81 and 83 while being held and held by the guide rails 75, and covers the rear end of each swing sorting plate 74. In particular, the mounting screw 8
1 is screwed to the rear side end of each swing selection plate 74 after the back cover 77 is inserted, whereby each swing selection plate 7
4 is fixed integrally with the back cover 77. By removing the back cover 77, it is possible to assemble and remove the respective swing sorting plates 74 (removal / insertion into / from the guide rail 75).

A monitoring window 79 made of a transparent plate is provided on the back cover 77, so that the inside of the frame 11, that is, the swing sorting plate 74, the distribution gutter 72, and the like can be visually recognized from the outside.

The supply gutter 68 and the oscillating sorting plate 7 having the above-described configurations are used.
The sorting unit 10B (the frame 11) into which the motor 4 is assembled is operated by transmitting the driving force of the main motor 120, and the rotational driving force is converted into a reciprocating driving force by a crank mechanism (cam mechanism). It swings (vibrates) in the direction. The mixed rice K supplied on the oscillating sorting plate 74 is converted into brown rice G and paddy M (those that cannot be removed) by the left and right swinging (vibration) of the oscillating sorting plate 74. This is a configuration in which the mixed rice K is sorted.

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 rocking 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.

Also, the falling-side end of the swing sorting plate 74 (FIG. 1)

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 guided to the screw conveyor 50 of the first grain gutter 48. 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 to the upstream side.

Further, a switching valve 53 is provided immediately after the paddy returning thrower 52 (on the way of the paddy returning 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.

On the other hand, the mixed rice K sorted (separated) by the fixed partition plate 78 and the movable partition plate 80 is supplied to the mixed rice discharge port 8.
The brown rice G guided to 6 and sorted (separated) by the movable partition plate 80 is guided to the brown rice outlet 88.

In this case, the movable partition plate 80 has a male screw shaft 92 whose axial direction is the left-right direction of the swing sorting plate 74.

It is conveyed to the mixed rice elevator 54 by the screw conveyor 50, and further sent to the mixed rice tank 56 by the mixed rice elevator 54. The mixed rice K sent into the mixed rice tank 56 is guided to the sorting unit 10B when a predetermined amount has been accumulated.

In the sorting section 10 B, the mixed rice K dropped into the supply gutter 68 is received by each distribution gutter 72, distributed to each swing sorting plate 74, and distributed and supplied to each of the communication input ports 85. The mixed rice K supplied on each of the rocking sorters 74 is caused by the left and right swinging (vibration) of the rocking sorter 74, so that the brown rice G, the paddy M, and the mixed rice K in which these are mixed are mixed.
And be sorted out.

Further, the paddy M sorted (separated) by the fixed partition plate 78 is guided to the paddy return port 84, and from this paddy return port 84, the paddy return hopper 90, the screw conveyor 50 of the first grain trough 48, and The rice is returned to the upstream side of the pair of hulling rolls 22 and 24 again by the hulling thrower 52.
Further, the mixed rice K sorted (separated) by the fixed partition plate 78 and the movable partition plate 80 is discharged from the mixed rice discharge port 86, and is fed by the screw conveyor 102 to the first gutter 48.
To the screw conveyor 50. 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 moving partition plate 80 is discharged from the brown rice discharge port 88, and is discharged by the screw conveyor 102 to the brown rice discharge lower 108.
After being conveyed to the boiled rice, it is repelled by the brown rice discharge thrower 108 and taken out of the brown rice extraction gutter 110 to the outside.

In this hulling device 10, the distribution gutter 72A corresponding to the topmost swing sorting plate 74A among the distribution gutters 72 has a communication input port 85A with the swing sorting plate 74A. Separately, since the dropout 87 for directly supplying the mixed rice K from the supply trough 68 to the rocking sorter plate 74A located at the uppermost position is provided, the rocker sorter plate 74A positioned at the uppermost position is provided. Not only the communication input port 85A but also the drop port 8
7, mixed rice K is supplied.

Therefore, since the distribution gutters 72 (72A) are provided adjacent to each other, the distribution gutters 72A corresponding to the rocking sorting plate 74A positioned at the highest position among the distribution gutters 72 are provided.
Even if the communication input port 85A with the swing sorting plate 74A is restricted (disturbed) by another distribution gutter 72 located next to it and cannot be provided sufficiently large, as a result, it is at the highest position. The supply amount of the mixed rice K to the located rocking sorting plate 74A does not become insufficient (the supply amount of the mixed rice K does not decrease compared to the other rocking sorting plates 74).

As described above, in the hulling device 10 according to the present embodiment, when the number of distribution gutters 72 (communication input ports 85) provided adjacent to each other is increased, Even if it is not possible to provide a sufficiently large communication opening 85A for the distribution gutter 72A with the swing sorting plate 74A corresponding to the upper swing sorting plate 74A, the uppermost swing sorting plate 74A. Can sufficiently supply the mixed rice K, and the supply amount of the mixed rice K does not decrease as compared with the other swinging sorting plates 74.

[0072]

As described above, the distribution gutter structure of the hulling device according to the present invention can sufficiently supply the mixed rice to the rocking sorter plate located at the uppermost position as compared with other rocking sorter plates. It has an excellent effect that the supply of mixed rice does not decrease.
