FIG. 1 is a sectional view showing the entire configuration of a hulling device 10 according to an embodiment of the present invention.
FIG. 2 schematically shows the entire configuration of the hulling device 10. FIG. 3 is an external perspective view of the hulling device 10.

The hulling apparatus 10 is for removing the supplied hulling M and extracting it as brown rice G, and is composed of a hulling unit 10A and a sorting unit 10B as a whole.

The hulling unit 10A is provided with a hulling supply hopper 12 which is open on the upper surface so that the hulling M is fed. The paddy supply hopper 12 has a tapered shape in which the opening is rectangular and gradually narrows toward the bottom. At the bottom of the paddy supply hopper 12, a rectangular supply port 1 is provided.
4 are provided, and the paddy M is sequentially supplied from the supply port 14
It flows into OA.

The supply port 14 is provided with a paddy supply shutter 16. This paddy supply shutter 16
It can be opened and closed by the driving force of a paddy supply motor (not shown).
2 is in the closed state when it is put into
Is supplied to the paddy supply hopper 12, and is controlled to be opened when the operation switch of the apparatus is operated.
Then, the opening degree of the paddy supply shutter 16 is controlled in accordance with a signal from a mixed rice sensor 66 disposed in a mixed rice tank 56 described later to limit the amount of the paddy M passing through the supply port 14. You can do it.

The paddy supply hopper 12 has a paddy sensor 1
8 is attached, and it can be detected whether or not the paddy M is present in the paddy supply hopper 12.

A hulling chamber 20 is provided below the supply port 14. In the hulling room 20, a pair of hulling rolls 22, 2
4 are provided. These pair of hulling rolls 22, 2
Numerals 4 are arranged so as to face each other and to have the tangent line at the closest position inclined upward to the right in FIG.
The rice M that has flowed into the hulling chamber 20 from the supply port 14 is guided to the closest position of the pair of hulling rolls 22 and 24. In addition, a pair of hulling rolls 22, 2
The standard clearance size of the closest position of 4 is 0.8 mm,
It can be adjusted in 1mm increments. This adjustment is adjusted by a roll interval adjusting motor (not shown).

The pair of hulling rolls 22 and 24 are rotated by the driving force of the main motor 120 being transmitted. In this case, the rotational speeds are slightly different from each other. That is, the hulling roll 22 located on the left side of FIG.
The hulling roll 24 located on the right side of FIG. For this reason, at the point of contact of the two closest positions, the relative rotation of each other occurs, and since the thickness of the rice M entering the closest position is larger than the gap size, the rice M is rubbed, so-called hulling (draining). Processing) is performed. In the following, the paddy M that has passed through the pair of hulling rolls 22 and 24 and that has been subjected to dehulling processing is referred to as hulled rice S. In this hulled rice S, a large amount of unhulled brown rice G, a small amount of unhulled rice M, and chaff N are mixed.

A diffusion plate 26 is disposed on the side of the pair of hulling rolls 22 and 24 on the hulling rice discharge side. This diffusion plate 26
Has a role of diffusing the hulled rice S discharged from the pair of hulling rolls 22 and 24 from the near side to the far side of FIG.

The bottom wall 28 of the hulling chamber 20 is inclined downward, and the hulling rice S diffused by the diffusion plate 26

Below the hulling chamber 20, a wind selection chamber 30 is provided. The air selection chamber 30 is provided with upper and lower air selection paths 34 and 36 by partition walls 32, and these air selection paths 34 and 36 communicate with a suction port 40 of a rice husk discharge blower 38. As a result, the hulled rice S guided to the wind selection chamber 30 has the rice husk N and pity T (immature grains, which are immature grains and almost no husks with little hull) sucked into the rice husk discharge blower 38. It is designed to be absorbed by force. The sucked rice hulls N are discharged to the outside through the rice husk discharge gutters 42.

Here, the rice husk discharge gutter 42 for discharging the rice husk N sucked by the rice husk discharge blower 38 to the outside is configured so as to be able to be vertically divided into two parts at an intermediate portion thereof. By separating the upper discharge gutter 42A from the lower discharge gutter 42B, the apparatus can be made compact as a whole.

Here, a lid 43 is detachably provided in the opening of the lower discharge gutter 42B after the upper discharge gutter 42A is detached. As shown in detail in FIGS. 4 and 5, the lid 43 is formed in a dish shape by, for example, press-drawing a plate material, and further, a rice grain (brown rice G or chaff M) is formed on the bottom surface. A large number (for example, 100) of recesses 45 that can enter each grain are formed.
Further, the inside surface of the lid 43 is coated with black or white.

Therefore, when the upper discharge gutter 42A is detached from the lower discharge gutter 42B, if the lid 43 is attached to the opening of the lower discharge gutter 42B, it is possible to supply brown rice G from the outside. Invasion of small animals (rats, etc.) can be prevented. Further, when the apparatus in which the upper discharge gutter 42A is connected to the lower discharge gutter 42B is operated, the lid 43 can be used as an inspection dish (so-called carton) for brown rice G (paddy M).

The lid 43 may be a plastic molded product.

A second grain gutter 44 is provided immediately below the lower wind selection path 36 in communication with the lower wind selection path 36. The second grain trough 44 is provided along the front-back direction (depth direction) of the apparatus. As a result, since the pity T is heavier than the chaff N, the pity T is not sucked from the upper wind selection path 34 (does not climb up), and if it is slightly sucked up in the lower wind selection path 36, it cannot withstand this suction. And is guided by the second grain gutter 44.

A screw conveyor 46 is provided at the bottom of the second grain gutter 44, and the pity T in the second grain gutter 44 is collected and collected at one end (the front side of the apparatus, the front side of FIG. 1). You can do it. The screw conveyor 46 is rotated by the driving force of the main motor 120 being transmitted.

A first grain gutter 48 is provided below the wind selection chamber 30 having the above configuration. The first grain gutter 48 is formed by the bottom wall 37 of the wind selection chamber 30 on the side of the second grain gutter 44.

The drop on the screw on the front side of the apparatus (on the front side of the paper surface of FIG. 1) is selected by the selection unit 10B described later and needs to be hulled again by the pair of hulling rolls 22 and 24.
The paddy M from the sorting unit 10B is sent. The paddy M from the sorting unit 10B that has fallen on the screw on the front side of the screw conveyor 50 is accumulated at the front end of the paper surface in FIG. 1, is repelled by the paddy return thrower 52, and is again upstream of the pair of hulling rolls 22 and 24. It is a configuration that is returned to the side.

The screw conveyer 50 and the paddy return thrower 52 are rotated by the driving force of the main motor 120 being transmitted.

On the other hand, a mixed rice raising and lowering machine 54 is connected to an end of the screw conveyor 50 on the back side of the apparatus (on the back side of FIG. 1). The mixed rice raising and lowering machine 54 is erected in the vertical direction, is guided from the air selection chamber 30, and is conveyed to the rear end of the apparatus by a screw of the screw conveyor 50 on the rear side of the apparatus (the rear side of the paper in FIG. 1). The mixed rice K is transported to the uppermost part of the hulling device 10 and sent to the mixed rice tank 56 located at the uppermost position of the hulling device 10.
It should be noted that the mixed rice elevator 54 also operates by transmitting the driving force of the main motor 120.

The mixed rice tank 56 is formed in a conical hopper shape, and is covered with a box-shaped casing 58. The mixed rice K lifted and conveyed by the mixed rice elevator 54 is accumulated in the mixed rice tank 56. An overflow pipe 60 is connected to a part of the side wall of the mixed rice tank 56. When a predetermined amount or more of the mixed rice K is accumulated in the mixed rice tank 56, a part of the mixed rice K is removed. Through the overflow pipe 60, it is returned to the upstream side of the pair of hulling rolls 22 and 24 in the hulling chamber 20.

A mixed rice supply shutter 64 is attached to the supply port 62 at the bottom of the mixed rice tank 56. The mixed rice supply shutter 64 can be opened and closed by the driving force of a mixed rice supply motor (not shown), and is operated by a signal from a mixed rice sensor 66 disposed in the mixed rice tank 56. When the mixed rice K in the mixed rice tank 56 is less than a predetermined amount, it is controlled to be closed, and when it is more than a predetermined amount, it is controlled to be opened. The opening of the mixed rice supply shutter 64 is set arbitrarily in advance, so that the amount of mixed rice K passing through the supply port 62 can be limited.

A sorting unit 1 is provided below the mixed rice tank 56.
0B is arranged, and the mixed rice K passed through the supply port 62
Are guided to the sorting unit 10B.

A distribution plate 68 is provided at the top of the sorting unit 10B. The distribution plate 68 is inclined toward one side of the device (downward to the right in FIG. 1), and has a surface on its right side with an infinite number of substantially stepped or substantially triangular shapes with the right side standing and the left side gently inclined. The projections are formed continuously. The distribution plate 68 is simultaneously swung when the sorting unit 10B is swung (vibrated) in the left-right direction in FIG. 1 as a whole, so that the mixed rice K dropped from the supply port 62 is pushed out on the right side of the projection. Thus, the light is scattered over the entire surface while gradually moving to the right in FIG. A leveling plate 70 is attached to the ceiling near the right end of the distribution plate 68, and serves to level the mixed rice K dropped on the distribution plate 68.

At the most downstream end (right end in FIG. 1) of the distribution plate 68, there are provided six distribution gutters 72 along the front-rear direction of the apparatus (from the near side to the far side in FIG. 1). I have. These distribution gutters 72 are independently communicated with six swing sorting plates 74 which are stacked and arranged at predetermined intervals below the distribution plate 68, respectively. Can be equally distributed and supplied to the respective swing sorting plates 74.

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 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 distribution trough 72 falls to the vicinity of the corner which is the fulcrum. Near the corner, a rectangular flat plate 76
Is provided. Thereby, the slip of the mixed rice K is improved, and the mixed rice K is promptly spread over the entire surface of the swing sorting plate 74.

The sorting unit 10B (its main body) composed of the distribution plate 68 and the six swinging sorting plates 74 having the above-described structure operates by transmitting the driving force of the main motor 120, and the rotational driving force is applied to the crank mechanism. (Cam mechanism) is converted into a reciprocating driving force and swings (vibrates) in the left-right direction in FIG. The mixed rice K supplied on the swing sorting plate 74 is
By the left and right swinging (vibration) of the swinging selection plate 74, the rice is separated into brown rice G, unhulled rice M (one that could not be dehulled), 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 rocking sorting plate 74 so as to be pushed out by the projections. It will move to the left side of the rocking sorter 74 sequentially so as to float above the layer and slide down on the surface of the layer. Due to the difference in the degree of the shift, the swing sorting plate 7
4, the brown rice G is concentrated in the right region of FIG. 1, the mixed rice K is concentrated in the central region, and the paddy M is concentrated in the left region, and is sorted (separated). 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 and a movable partition plate 80 are provided at the front end of the drawing.

The fixed partition plate 78 is located near the boundary between the paddy M and the mixed rice K separated (separated) by the swinging separation plate 74 as described above,

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 via the discharge duct 55. Therefore, if this switching valve 53 is operated to be in the “open” state,
The paddy M to be returned by the paddy return thrower 52 can be directly discharged to the outside of the apparatus.

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.

Here, the movable partition plate 80 has a male screw shaft 92 having the left-right direction of the swing sorting plate 74 as the axial direction.
Is screwed into. The male screw shaft 92 is prevented from moving in the axial direction and is rotated by the driving force of the partition motor 94. For this reason, the partition plate motor 9
The movable partition plate 80 can be moved in the left-right direction in FIG. 1 by driving the 4 and rotating the male screw shaft 92.

Movement of this movable partition plate 80 (position)
Is determined by the degree of sorting at the time of sorting brown rice by swinging of the swing sorting plate 74. In other words, depending on the type of rice and the surrounding environment, there are cases where sorting is easy and difficult, and
When the sorting is easy, the area where the brown rice G is dropped is widened, so the moving partition 80 is moved to the left in FIG.
On the other hand, when sorting is difficult, the area where the brown rice G falls is narrowed, so that the movable partition plate 80 can be moved to the right in FIG. Reference numeral 93 denotes both partition plates 78,

The other end of the dust collection duct 112 is located at the lowermost end of the hulling chamber 20 (near the wind selection path 34 of the wind selection chamber 30). Therefore, the dust in the brown rice discharge blower 108 is sucked by the suction force of the rice husk discharge blower 38 and discharged to the outside together with the rice hull N, so that the dust is not scattered from the brown rice extraction gutter 110.

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 even in the closed state, is pressed by the discharging force of the brown rice G to discharge the brown rice G. 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.

In the hulling device 10 having the above configuration, the hulling unit 10
When the paddy M is put into the paddy supply hopper 12 of A and the operation of the apparatus is started, the paddy M flows into the paddy chamber 20 sequentially, and is supplied between the pair of paddy rolls 22 and 24 to be padded (removed).ぷ Processing) is performed. The hulled rice S that has passed through the pair of hulling rolls 22 and 24 and that has been de-hulled flows into the wind selection chamber 30 sequentially,
The rice husks N and pity T mixed into the rice husk discharge blower 3
It is sucked by the suction force of 8. The rice husk N is discharged to the outside through the rice husk discharge gutter 42, and the pity T is the second grain gutter 44.
Is collected and collected by the screw conveyor 46 on the front side of the apparatus.

On the other hand, the rice husk N and pity T
The mixed rice K from which etc. has been removed is guided to the first grain gutter 48,
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 10B, the mixed rice K dropped on the distribution plate 68 is passed through six distribution gutters 72 to each of the swinging selection plates 74.
Are equally distributed and supplied. 6 swing sorting plates 7
The mixed rice K supplied on the top 4 is separated into brown rice G, paddy M, and mixed rice K in which these are mixed by the right and left swing (vibration) of the swing sorting plate 74.

Further, the paddy M sorted (separated) by the fixed partition plate 78 is guided to the paddy return port 84, from which 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 grain trough 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.

Here, in the hulling apparatus 10, small animals such as rats enter the apparatus through the opening of the chaff discharge gutter 42 for discharging the chaff N sucked by the chaff discharge blower 38 to the outside. It is possible. However, since the rice husk discharge gutter 42 can separate the upper discharge gutter 42A from the lower discharge gutter 42B, and since the lid 43 is detachably attached to the opening of the lower discharge gutter 42B, The upper discharge gutter 42A is detached from the lower discharge gutter 42B, and the cover 43 is attached to the opening of the lower discharge gutter 42B as shown in FIG. 5, so that invasion of small animals from the outside can be prevented. it can. Therefore, such small animals do not suffer accidental damage such as biting the wiring of the device or the drive belt.

Further, the lid 43 is formed in a dish shape, and further, on the bottom surface thereof, there are formed a large number of concave portions 45 into which rice grains (brown rice G or unhulled rice M) can enter each grain.
Therefore, when the apparatus in which the upper discharge gutter 42A is connected to the lower discharge gutter 42B is operated, the lid 43 is removed to remove the rice grains (brown rice G or unhulled M) into an inspection dish (so-called carton).
Can be used as Therefore, whether the escape process is properly performed (for example, whether the escape rate is appropriate,
Confirmation inspection of the presence or absence of a body crack, the degree of skin roughness, etc.) can be easily performed.

The following items can be cited as the confirmation inspections performed using the lid 43 and the corresponding countermeasures. -Whether the loss rate is appropriate: Check the mixing rate of a small amount of unpolished rice M mixed into the hulled rice S. When the mixing ratio of the paddy M is high, the roll interval between the pair of paddy rolls 22 and 24 is narrowed. -Check for cracks in the body: Check the quality of brown rice G. If the distance between the pair of hulling rolls 22 and 24 is too narrow, the number of cracks in the body increases, so the roll interval between the pair of hulling rolls 22 and 24 is optimally adjusted according to the presence or absence of the body crack. -Degree of rough skin: Check the quality of brown rice G. If the distance between the pair of hulling rolls 22 and 24 is too small, this roughening of the skin will increase. Therefore, the roll interval between the pair of hulling rolls 22 and 24 is optimally adjusted according to the degree of the roughening of the skin.

In this case, as described above, the number of the concave portions 45 is set to one.
If it is set to 00, brown rice G properly processed
, In other words, the content ratio of defective hulled rice S, can be determined at a glance, and the confirmation test of the above-mentioned loss rate, body split rate, skin roughness rate, etc. can be performed more easily.
