Description

この発明は、籾摺選別機に関し、特にインペラ式の籾摺選別機に関するものである。 The present invention relates to a hull sorter, and more particularly to an impeller type hull sorter.

インペラ式の籾摺選別機は、インペラの回転速度の変化に応じて、穀粒の供給量を関連的に調節して、穀粒に与える衝撃力を調整し、砕米や肌擦れ調整するものであるが、インペラ式の籾摺装置はロール式の籾摺装置に比べ、籾摺り穀粒の水分値に対する脱ぷ率はさほど影響を受けないが、肌擦れ率の発生や、発芽率、あるいは胚芽脱落率は籾摺り穀粒の水分値の影響を受け、水分値が高いほどその影響が大きいことが知られている。 Impeller type rice hull sorter adjusts the amount of grain supply according to the change of impeller rotation speed, adjusts the impact force applied to the grain, and adjusts broken rice and rubbing. However, the impeller-type hulling device is less affected by the moisture content of the hulled grain than the roll-type hulling device, but the occurrence of the rubbing rate, germination rate, or germ loss It is known that the rate is affected by the moisture value of the hulled grain, and the higher the moisture value, the greater the effect.

特開２００３−１９４４０号公報に記載されたインペラ式の籾摺選別機は、高脱ぷ率を維持しながら、穀粒が所定水分値以上になると、インペラの回転数を基準回転数より増加しないように制御し、肌擦れや、胚芽の脱落を防止しようとするものである。 The impeller-type hull sorter described in Japanese Patent Application Laid-Open No. 2003-19440 does not increase the rotation speed of the impeller from the reference rotation speed when the grain becomes a predetermined moisture value or more while maintaining a high deflation rate. In this way, it is intended to prevent skin rubbing and detachment of germs.

特開２００３−１９４４０号公報Japanese Patent Laid-Open No. 2003-19440

上記特許文献１記載の発明は、作業能率が低い、即ち機外に排出する玄米量が少ないと、インペラに戻される玄米量が増加し、インペラで二度摺りされる玄米量が増加し、玄米の肌ずれ（傷）や胚芽部分が除去されやすい。 In the invention described in Patent Document 1, when the work efficiency is low, that is, when the amount of brown rice discharged outside the machine is small, the amount of brown rice returned to the impeller increases, and the amount of brown rice slid twice by the impeller increases. The skin slip (wound) and germ part are easily removed.

そこで本発明の課題は、肌ずれ玄米や胚芽部分が無くなる玄米を減らすことができるインペラ式の籾摺選別機を提供することである。 Accordingly, an object of the present invention is to provide an impeller-type rice hull sorter that can reduce brown rice from which skin misaligned brown rice and germ portions are eliminated.

本発明の上記課題は以下の解決手段により解決される。
すなわち、請求項１記載の発明は、インペラ（１１）を有する籾摺部（１）と、インペラ（１１）の回転数を可変速とするインペラ回転数可変速手段（５４）と、インペラ（１１）により籾摺りされて籾と玄米を含む混合米を受ける混合米受け部（２２）と、該混合米受け部（２２）の底部出口に設けた混合米の供給量を調節する混合米供給量調節弁（２４）と、混合米受け部（２２）から送られて来る混合米中の籾と玄米とを選別する複数段からなる揺動選別板（２５）と、該揺動選別板（２５）から玄米を機外に取り出すための移動自在の玄米仕切板（２９）と、籾を籾摺部（１）に戻すための籾仕切板（２８）と、玄米仕切板（２９）の配置位置を検出する手段（３６）と、該玄米仕切板（２９）の配置位置の検出手段（３６）により検出される玄米仕切板（２９）の配置位置に応じてインペラ回転数を調節する制御装置（５５）とを備えたインペラ式籾摺選別機である。 The above-mentioned problems of the present invention are solved by the following solution means.
That is, the invention described in claim 1 includes a hulling portion (1) having an impeller (11), impeller rotation speed variable speed means (54) for changing the rotation speed of the impeller (11), and an impeller (11 ) And a mixed rice receiving portion (22) for receiving mixed rice containing rice bran and brown rice, and mixed rice supply amount adjustment for adjusting the supply amount of mixed rice provided at the bottom outlet of the mixed rice receiving portion (22) Valve (24), swing sorting plate (25) consisting of a plurality of stages for sorting rice bran and brown rice in mixed rice sent from mixed rice receiver (22), and swing sorting plate (25) The arrangement position of the movable brown rice partition plate (29) for taking out the brown rice out of the machine, the straw partition plate (28) for returning the rice cake to the hulling portion (1), and the brown rice partition plate (29) By means for detecting (36) and means for detecting the arrangement position of the brown rice partition plate (29) (36) It is in accordance with the arrangement position of the brown rice partition plate (29) to be issued and a control unit (55) for adjusting the impeller rotational speed impeller type hulling sorter.

請求項２記載の発明は、玄米仕切板（２９）の仕切り位置が揺上側に調節されると前記混合米供給量調節弁（２４）の供給量を低い方に連動させる請求項１記載の籾摺選別機である。 According to a second aspect of the present invention, when the partition position of the brown rice partition plate (29) is adjusted to the rocking side, the supply amount of the mixed rice supply amount adjustment valve (24) is interlocked with the lower one. It is a sliding sorter.

請求項１記載の発明によれば、玄米仕切板２９の配置位置に応じてインペラ１１の回転数を変更とする構成を採用することで、玄米の肌ずれ（傷）や胚芽部分の除去を少なくできる。すなわち、揺上側に玄米仕切板２９を移動させると選別能率が低下し、インペラ１１のある籾摺部１に循環する玄米量が増加する。そこで、インペラ１１の回転数を低下させることで肌ずれや胚芽部分による玄米の損傷を低減させることができる。 According to the first aspect of the present invention, by adopting a configuration in which the rotation speed of the impeller 11 is changed according to the arrangement position of the brown rice partition plate 29, the removal of skin slippage (scratches) and germ portions of the brown rice is reduced. it can. That is, when the brown rice partition plate 29 is moved to the rocking side, the sorting efficiency is lowered, and the amount of brown rice circulating in the rice hull portion 1 with the impeller 11 is increased. Therefore, by reducing the rotational speed of the impeller 11, it is possible to reduce brown rice damage caused by skin slippage or germ portions.

請求項２記載の発明によれば、請求項１記載の発明の効果に加えて、玄米仕切板２９の仕切り位置が揺上側に移動調節されると、混合米供給量調節弁２４のからの揺動選別板２５への混合米供給量をより低い方に連動させることで、インペラ１１に戻される玄米量を
減らし、玄米の肌ずれ（傷）や胚芽部分の除去がないようにすることができる。 According to the invention described in claim 2, in addition to the effect of the invention described in claim 1, when the partition position of the brown rice partition plate 29 is moved and adjusted to the rocking side, the shaking from the mixed rice supply amount adjustment valve 24 By linking the amount of mixed rice supplied to the moving sorting plate 25 to the lower side, the amount of brown rice returned to the impeller 11 can be reduced, so that there is no skin slippage (scratches) or removal of the germ portion of the brown rice. .

以下、図面に示すこの発明の実施例の形態について説明する。
図１により本実施例のインペラ式の籾摺選別機の全体構成について説明する。このインペラ式籾摺選別機は、籾摺部１、摺落米風選部２、風選後の混合米を籾・玄米に分離選別する混合米選別部３、混合米揚穀機４，玄米揚穀機５，本機駆動モータM等により構成されている。なお、図１を正面側とする。 Embodiments of the present invention shown in the drawings will be described below.
The overall configuration of the impeller-type hull sorter of this embodiment will be described with reference to FIG. This impeller-type rice hull sorter has a rice hull portion 1, a sliding rice-style rice selection portion 2, a mixed rice sorting portion 3 that separates and sorts mixed rice after wind selection into straw and brown rice, a mixed rice cerealing machine 4, brown rice It is composed of a masher 5, a machine drive motor M, and the like. 1 is the front side.

籾摺部１は、インペラ式の籾摺装置であって、摺落米風選箱体６の一側に設けられていて、籾ホッパ７、籾供給筒８、籾摺ケース９、籾摺ケース９に軸架した籾摺軸１０、籾摺軸１０に取り付けられているインペラ１１、摺落米を摺落米風選箱体６上部に設けた摺落米拡散室１４に移送供給する摺落米供給筒１２等により構成されている。 The hulling portion 1 is an impeller-type hulling device, and is provided on one side of the sliding rice-style sorting box 6, and includes a hull hopper 7, a hull supply cylinder 8, a hulling case 9, and a hulling case. 9 and the impeller 11 attached to the hull shaft 10, and the sliding-off that transports and supplies the smashed rice to the smashed rice diffusion chamber 14 provided on the top of the smashed rice-style sorting box 6. It consists of a rice supply cylinder 12 and the like.

先ず、籾ホッパ７に供給された籾粒は、籾シャッタ弁１９（図６）を開いて籾供給筒８を落下して後方から籾摺ケース９内のインペラ１１の中心部に供給され、回転しているインペラ１１に掬い取られ、遠心力によりインペラ１１の外周側に流動し、籾摺ケース９のライニング４６ａ，４６ｂ（図７）に衝突して籾摺されながら、摺落米供給筒１２を上昇して摺落米拡散室１４に移送供給され、摺落米風選部２に落下する。 First, the soot particles supplied to the soot hopper 7 open the soot shutter valve 19 (FIG. 6), drop the soot supply cylinder 8, and are supplied from the rear to the center of the impeller 11 in the tackle case 9 to rotate. The crushed rice supply cylinder 12 is scooped by the impeller 11 and flows to the outer peripheral side of the impeller 11 by centrifugal force, collides with the linings 46a and 46b (FIG. 7) of the hull case 9, and is crushed. , And is supplied to the sliding rice diffusion chamber 14 and falls to the sliding rice wind selection unit 2.

次に、摺落米風選部２について説明する。
摺落米風選部２は下部から上部に向かって選別風の流れる摺落米風選路１３を設け、摺落米拡散室１４を経て落下した摺落米は摺落米風選路１３の下部に供給される構成である。摺落米風選路１３の上方には吸引ケース１６に内装された吸引ファン１７があり、該吸引ケース１６の上部には排塵筒１８を接続している。 Next, the sliding rice wind selection unit 2 will be described.
The sliding rice wind selection section 2 is provided with a sliding rice wind selection path 13 through which the sorting wind flows from the lower part to the upper part. It is the structure supplied to the lower part. Above the sliding rice wind selection path 13, there is a suction fan 17 built in a suction case 16, and a dust exhaust cylinder 18 is connected to the upper part of the suction case 16.

こうして、籾摺部１により籾摺りされた摺落米は摺落米供給筒１２、摺落米拡散室１４を経て摺落米風選路１３の下部に落下供給され、摺落米風選部２において軽い籾殻類は摺落米風選路１３の上部に吸引され、吸引ファン１７、排塵筒１８を経て機外に排出され、比較的重い籾・玄米の混合米は摺落米受樋１５に供給される。
そして、摺落米受樋１５内に配置された螺旋２３により後ろ方向に搬送され、順次バケット２１内に入れられてエレベータ式の混合米揚穀機４内を上昇し、揺動選別型の混合米選別部３に供給される。 Thus, the smashed rice crushed by the smashing unit 1 is dropped and supplied to the lower part of the smashed rice wind selection path 13 through the smashed rice supply cylinder 12 and the smashed rice diffusion chamber 14. , The light rice husks are sucked into the upper part of the crushed rice wind path 13 and discharged to the outside of the machine through the suction fan 17 and the dust discharge cylinder 18, and the mixed rice of the relatively heavy rice cake / brown rice is the crushed rice receiver 15. To be supplied.
And it is conveyed backward by the spiral 23 arrange | positioned in the fallen rice receptacle 15, and it puts in the bucket 21 sequentially, raises the inside of the elevator-type mixing rice cereal machine 4, and is mixed by the swing selection type. Supplied to the rice sorting unit 3.

該混合米選別部３には混合米から籾と玄米に分離選別するために、その上段側に漏斗状の混合米タンク２２を配置し、下段側に多段の揺動選別板２５を配置している。
バケット２１により搬送された混合米は、混合米揚穀機４の頂部でバケット２１から混合米選別部３の漏斗状の混合米タンク２２に移される。該混合米タンク２２の底部にある幅狭の出口部には混合米供給弁調節モータ３７（図４）で作動する混合米供給量調節弁２４を設けている。該混合米供給量調節弁２４を揺動させることで出口部の開口面積を変えて、混合米の揺動選別板２５への供給量を調節する。 The mixed rice sorting unit 3 is provided with a funnel-shaped mixed rice tank 22 on the upper side and a multi-stage swing sorting plate 25 on the lower side for separating and sorting the mixed rice into rice bran and brown rice. Yes.
The mixed rice conveyed by the bucket 21 is transferred from the bucket 21 to the funnel-shaped mixed rice tank 22 of the mixed rice sorting unit 3 at the top of the mixed rice cerealing machine 4. A mixed rice supply amount adjustment valve 24 operated by a mixed rice supply valve adjustment motor 37 (FIG. 4) is provided at the narrow outlet portion at the bottom of the mixed rice tank 22. By swinging the mixed rice supply amount adjusting valve 24, the opening area of the outlet is changed, and the supply amount of the mixed rice to the swing sorting plate 25 is adjusted.

揺動選別板２５内の上方に設けられた空間に、混合米タンク２２の出口から排出された混合米は渡し樋２６により、揺動選別板２５に搬送される。
揺動選別板２５は摺落米風選路１３側が低くなるように斜め方向に互いに平行な棚が多段配置されている。また多段の揺動選別板２５の機体手前側、すなわち選別した米の排出側には縦方向に仕切る籾仕切板２８と玄米仕切板２９とが揺動選別板２５の揺下側から揺上側に順に配置されており、揺動選別板２５が全体として揺動すると混合米が揺動選別板２５上で揺動される間に、比重により選別され、籾仕切板２８より揺下側の揺動選別板２５からは籾が落下し、落下した籾はスロワ３１で戻り室３２に戻され、再度籾供給筒８を経てインペラ１１に供給される。籾仕切板２８と玄米仕切板２９の間には籾・玄米の混合米が落下し、玄米仕切板２９より揺上側の揺動選別板２５から玄米が落下する。こうして混合米中の籾と籾・玄米混合米及び玄米にそれぞれ分別される。 The mixed rice discharged from the outlet of the mixed rice tank 22 is conveyed to the swing sorting plate 25 by a transfer rod 26 in a space provided above the swing sorting plate 25.
In the swing sorting plate 25, shelves parallel to each other in an oblique direction are arranged in multiple stages so that the sliding rice wind selection path 13 side is lowered. Further, on the front side of the machine body of the multi-stage swing sorting plate 25, that is, on the discharged side of the sorted rice, a vertical partition plate 28 and a brown rice partition plate 29 are arranged from the swing side to the swing side of the swing sort plate 25. When the swing sorting plate 25 swings as a whole, while the mixed rice is swung on the swing sorting plate 25, the mixed rice is sorted by specific gravity and swings on the lower side from the partition plate 28. The soot falls from the sorting plate 25, and the fallen soot is returned to the return chamber 32 by the slot 31 and supplied again to the impeller 11 through the soot supply cylinder 8. Mixed rice of rice bran / brown rice falls between the straw partition plate 28 and the brown rice partition plate 29, and the brown rice falls from the swing sorting plate 25 on the upper side of the brown rice partition plate 29. In this way, the mixed rice is separated into rice bran, rice bran / brown rice mixed rice, and brown rice.

籾・玄米の混合米は螺旋２３により混合米揚穀機４に搬送され、順次バケット２１内に入れられてエレベータ式の混合米揚穀機４内を上昇して、再度揺動選別板２５に送られる。
また、玄米仕切板２９より揺上側の揺動選別板２５から落下した玄米は、玄米揚穀機５内のバケット３４に入れられて玄米揚穀機５を上昇して外部に排出される。 The mixed rice of brown rice and brown rice is conveyed to the mixed rice cerealing machine 4 by the spiral 23, sequentially put into the bucket 21, lifted in the elevator type mixed rice cerealing machine 4, and again on the swing sorting plate 25. Sent.
Further, the brown rice dropped from the swing sorting plate 25 on the upper side of the brown rice partition plate 29 is put in the bucket 34 in the brown rice cerealing machine 5, and is lifted and discharged to the outside.

上記構成からなるインペラ式籾摺選別機において、玄米仕切板２９を揺上側に移動させ機外に排出する玄米量を減少させる、すなわち籾摺選別機の作業能率を低くするとインペラ１１に戻される玄米量が比較的増加し、インペラ１１で二度摺りされる玄米量が比較的増加し、玄米の肌ずれ（傷）や胚芽部分が除去され易くなる。 In the impeller type rice hull sorter configured as described above, the brown rice partition plate 29 is moved upward to reduce the amount of brown rice discharged outside the machine, that is, when the work efficiency of the rice hull sorter is lowered, the brown rice returned to the impeller 11 The amount is relatively increased, the amount of brown rice that is rubbed twice with the impeller 11 is relatively increased, and the skin shift (scratches) and the germ portion of the brown rice are easily removed.

そこで、本実施例のインペラ式籾摺選別機では、玄米仕切板２９を移動可能として玄米仕切板２９の設置位置に応じてインペラ１１の回転数を可変速とする構成を採用して、前記従来技術の欠点である玄米の肌ずれ（傷）や胚芽部分の除去がないような構成を採用する。 Therefore, the impeller type rice hull sorter of the present embodiment adopts a configuration in which the brown rice partition plate 29 is movable and the rotation speed of the impeller 11 is variable depending on the installation position of the brown rice partition plate 29. Adopted a structure that does not remove brown rice skin shift (wound) and germ part, which are the disadvantages of the technology.

また、玄米仕切板２９の仕切り位置が揺上側に移動調節されると、混合米供給量調節弁２４からの揺動選別板２５への混合米供給量をより低い方に連動させることで、インペラ１１に戻される玄米量を減らし、玄米の肌ずれ（傷）や胚芽部分の除去がないようにすることができる。 Further, when the partition position of the brown rice partition plate 29 is moved and adjusted to the rocking side, the impeller is operated by interlocking the mixed rice supply amount from the mixed rice supply amount adjustment valve 24 to the swing sorting plate 25 to the lower side. The amount of brown rice returned to 11 can be reduced so that there is no skin slippage (scratches) or removal of the germ portion of the brown rice.

図２に示す上段の揺動選別板２５の平面図には、揺動選別板２５に供給されて選別される玄米と混合米と籾の分布領域がそれぞれ示されるが、籾が混在する混合米を籾摺選別機から排出しないようにするためには、玄米仕切板２９の配置位置を揺上側に移動させて混合米が混在しない玄米だけを機外へ排出するようにする。ただし、あまり玄米仕切板２９位置を揺上側に移動すると玄米排出量が減少し、この場合は作業能率が低下する。 The plan view of the upper swing sorting plate 25 shown in FIG. 2 shows the distribution areas of brown rice, mixed rice, and rice bran that are supplied to the swing sorting plate 25 and sorted. Is not discharged from the rice hull sorter, the arrangement position of the brown rice partition plate 29 is moved to the rocking side so that only the brown rice in which mixed rice is not mixed is discharged outside the machine. However, when the position of the brown rice partition plate 29 is moved to the rocking side, the amount of brown rice discharged is reduced, and in this case, the work efficiency is lowered.

すると、図２の籾層に流入してインペラ１１に戻る玄米量が増加し、インペラ１１側に戻った玄米に新たな衝撃が加わり、胚芽まで除かれたり傷がつくことになり玄米の品質が低下する。 Then, the amount of brown rice that flows into the cocoon layer in FIG. 2 and returns to the impeller 11 increases, and a new impact is applied to the brown rice that returns to the impeller 11 side. descend.

そこで、玄米仕切板２９の配置位置を揺上側に移動させるにつれてインペラ１１の回転数を低下させるように玄米仕切板位置検出センサ３６とインペラ回転調節モータ５４（図４）を連動制御する。 Therefore, the brown rice partition plate position detection sensor 36 and the impeller rotation adjusting motor 54 (FIG. 4) are controlled in conjunction so that the rotational speed of the impeller 11 decreases as the arrangement position of the brown rice partition plate 29 is moved to the rocking side.

インペラ１１の回転数が低下すると脱ぷ率が低下するため、揺動選別板２５上の籾層における籾の割合が高くなり、ひいてはインペラ１１に戻される玄米量が低下するため、インペラ１１で損傷される玄米の量を少なくすることができる。
逆に玄米仕切板２９の位置を揺下側に移動させると、機外に排出される玄米量が増加し、すなわち作業能率が高い状態になるため、インペラ１１の回転数を上昇させて脱ぷ率を上昇させて揺動選別板２５に供給する玄米量を増加させる。 When the rotational speed of the impeller 11 is reduced, the detachment rate is reduced, so that the ratio of the cocoon in the cocoon layer on the swing sorting plate 25 is increased, and as a result, the amount of brown rice returned to the impeller 11 is reduced, and the impeller 11 is damaged. Can reduce the amount of brown rice produced.
Conversely, when the position of the brown rice partition plate 29 is moved downward, the amount of brown rice discharged outside the machine increases, that is, the work efficiency becomes high. The amount of brown rice supplied to the swing sorting plate 25 is increased by increasing the rate.

前述の玄米仕切板２９とインペラ１１の回転数との制御にさらに混合米供給量調節弁２４の開度を調節する制御を加えても良い。
すなわち、玄米仕切板２９を揺上側に位置するにつれて混合米供給量調節弁２４の開度を狭くして揺動選別板２５への供給量を減少させる。すると籾層に流入する玄米量が減少し、インペラに戻る玄米量が減少することができる。
逆に、玄米仕切板２９を揺下側に位置するにつれて混合米供給量調節弁２４の開度を広くして揺動選別板２５への供給量を増加させることで作業能率を上昇させることができる。 Control for adjusting the opening degree of the mixed rice supply amount adjustment valve 24 may be added to the control of the brown rice partition plate 29 and the rotation speed of the impeller 11 described above.
That is, as the brown rice partition plate 29 is positioned on the rocking side, the opening of the mixed rice supply amount adjustment valve 24 is narrowed to reduce the supply amount to the swing sorting plate 25. Then, the amount of brown rice flowing into the rice bran layer can be reduced, and the amount of brown rice returning to the impeller can be reduced.
Conversely, the working efficiency can be increased by increasing the supply amount to the swing sorting plate 25 by increasing the opening of the mixed rice supply amount adjustment valve 24 as the brown rice partition plate 29 is positioned on the lower side. it can.

FIG. 3C shows a simplified diagram viewed from the direction of arrow A in FIG. As shown in FIG. 3, the movement of the arrangement position of the brown rice partition plate 29 is caused by a long hole 38 a formed in the cover 38 with a knob 29 a penetrating the front wall body (cover) 38 of the machine body and connected to the brown rice partition plate 29. When the brown rice partition plate 29 is moved along the rail 39, the potentiometer (brown rice partition plate position detection sensor connected to the brown rice partition plate 29 on the back side of the front wall body 38 of the machine body is operated. ) 36 is arranged, and the arrangement position of the brown rice partition plate 29 can be detected. In the same manner, the hook partition plate 28 is also moved and adjusted in the left-right direction along the long hole 38b formed in the cover 38 with the knob 28a connected to the cover partition plate.

供給弁調節モータ３７で作動する混合米供給量調節弁２４の開閉の程度は混合米供給量調節弁２４の作動位置を検出する供給量調節弁作動位置検出センサ５２により検出される。該供給量調節弁作動位置検出センサ５２と玄米仕切板２９の配置位置を検出する玄米仕切板位置検出センサ３６の両方のセンサ５２、３６で検出された混合米供給量調節弁２４の開閉の程度と玄米仕切板２９の配置位置とに合わせて、インペラ回転センサ５３により検出されるインペラ１１の回転数をインペラ回転調節モータ５４（図４）により調節し、また混合米供給量調節弁２４をモータ３７により調節する制御を制御装置５５（図４）が行う。
上記玄米仕切板２９の配置位置と混合米供給量調節弁２４の開閉の程度の調整は図４の制御ブロック図に示す制御装置５５に基づき図５に示すフローチャートに従って行われる。 The degree of opening and closing of the mixed rice supply amount adjustment valve 24 operated by the supply valve adjustment motor 37 is detected by a supply amount adjustment valve operating position detection sensor 52 that detects the operating position of the mixed rice supply amount adjustment valve 24. The degree of opening and closing of the mixed rice supply amount adjustment valve 24 detected by both the sensors 52 and 36 of the supply amount adjusting valve operating position detection sensor 52 and the brown rice partition plate position detection sensor 36 for detecting the arrangement position of the brown rice partition plate 29 The rotational speed of the impeller 11 detected by the impeller rotation sensor 53 is adjusted by an impeller rotation adjustment motor 54 (FIG. 4) in accordance with the arrangement position of the brown rice partition plate 29 and the mixed rice supply amount adjustment valve 24 is driven by a motor. The control device 55 (FIG. 4) performs the control adjusted by 37.
Adjustment of the arrangement position of the brown rice partition plate 29 and the degree of opening and closing of the mixed rice supply amount adjustment valve 24 is performed according to the flowchart shown in FIG. 5 based on the control device 55 shown in the control block diagram of FIG.

なお、本実施例では玄米仕切板２９の位置とインペラ１１の回転数を連動制御する構成であるが、例えば玄米仕切板位置が設定位置よりも揺上位置にきたときにインペラ１１の回転数を低下させ、設定位置よりも揺下位置の場合には標準回転数すなわち設定回転数にする構成としても良い。 In this embodiment, the position of the brown rice partition plate 29 and the rotational speed of the impeller 11 are controlled in conjunction with each other. However, for example, when the position of the brown rice partition plate is higher than the set position, the rotational speed of the impeller 11 is set. In the case of the lowering position than the set position, the standard rotation speed, that is, the set rotation speed may be used.

図６には籾摺選別機の右側面図を示すが、籾ホッパ７から籾供給筒８を経由してインペラ投入部（籾摺ケース）９において、インペラ回転軸（籾摺軸）１０にプッシャーファン４１を設け、プッシャーファン４１の周囲をリングシュラウド４２で覆い、インペラ１１の回転と同時に、インペラ１１に向けて圧風を送る構成を採用している。
上記リングシュラウド４２によりインペラ投入部９の穀粒流れをスムーズにし、インペラ１１への籾供給量を安定化させることができる。 FIG. 6 shows a right side view of the hull sorter, and a pusher is applied to the impeller rotating shaft (hulling shaft) 10 in the impeller loading section (hulling case) 9 from the hull hopper 7 via the hull supply cylinder 8. A configuration is adopted in which a fan 41 is provided, the periphery of the pusher fan 41 is covered with a ring shroud 42, and the compressed air is sent toward the impeller 11 simultaneously with the rotation of the impeller 11.
The above-described ring shroud 42 can smooth the grain flow of the impeller input unit 9 and stabilize the supply amount of straw to the impeller 11.

なお、リングシュラウド４２の機体内側開口部には網体４３を設けておくと、不要なゴミ等がリングシュラウド４２の中に入っていても、容易に取り出す事ができ、インペラ１１に向けて流入することがない。また、籾供給筒８の頂部には点検用蓋４５を配置している。 If a net 43 is provided in the opening inside the fuselage 42 of the ring shroud 42, unnecessary dust can be easily taken out even if it enters the ring shroud 42, and flows toward the impeller 11. There is nothing to do. In addition, an inspection lid 45 is disposed on the top of the tub supply cylinder 8.

籾摺選別機を用いる作業の終了時に前記点検用蓋４５をあけて、ここから図示しないコンプレッサでエアをインペラ１１に向けて流入させることで、籾供給筒８とインペラ投入部９の内部に残った籾を排出することができる。また前記点検用蓋４５の裏面に鏡を配置しておくと、蓋４５を開けた状態で鏡に映るインペラ１１の回転軸１０を点検できる。 At the end of the operation using the hull sorter, the inspection lid 45 is opened, and air is introduced into the impeller 11 by a compressor (not shown) from here to remain inside the hull supply cylinder 8 and the impeller input portion 9. It can discharge the firewood. If a mirror is disposed on the back surface of the inspection lid 45, the rotating shaft 10 of the impeller 11 reflected on the mirror can be inspected with the lid 45 opened.

図７にはインペラ投入部９のケース４６の一部正面図を示す。ケース４６には合成樹脂製のライニング４６を厚さ方向で二層４６ａ，４６ｂに分けて設け、内側層４６ａを濃い色の材料で形成し、外側層４６ｂを薄い色又は透明の材料で形成している。そのため、ケース４６の適所に設けた長穴４６ｃ（図７の円I内に示す矢印Ｓ方向から見たケース外観）からケース内部を見て、図７の円II内の断面図に示すようにライニング４６ａ，４６ｂの交換時期がすぐ分かる。
すなわち、濃い色のライニング層４６ａが摩耗してなくなり長穴４６ｃからは薄い色又は透明のライニング層４６ｂだけしか見えなくなるとケース４６の内壁にライニング層４６ａ，４６ｂを施す時期であることが容易に分かるのでメンテナンス性が高くなる。 FIG. 7 shows a partial front view of the case 46 of the impeller charging unit 9. The case 46 is provided with a synthetic resin lining 46 divided into two layers 46a and 46b in the thickness direction, the inner layer 46a is formed of a dark color material, and the outer layer 46b is formed of a light color or a transparent material. ing. Therefore, the inside of the case is seen from a long hole 46c (appearance of the case viewed from the direction of arrow S shown in the circle I in FIG. 7) provided at an appropriate position of the case 46, as shown in the sectional view in the circle II in FIG. The time for replacement of the linings 46a and 46b can be known immediately.
That is, when the dark color lining layer 46a is not worn and only the light color or transparent lining layer 46b is visible from the elongated hole 46c, it is easy to apply the lining layers 46a and 46b to the inner wall of the case 46. As you can see, maintenance is high.

また、図８にインペラ投入部９のケース４６の一部正面図（図８（ａ））と一部後側面図（図８（ｂ））とインペラ１１の割りプーリ作動用レバー４７の取付部を示す図８（ａ）の矢印Ａ方向から見た図（図８（ｃ））を示す。インペラ回転軸１０に割プーリ４８，４８を設け、インペラ回転軸１０の回転数を変更することができる構成である。
また、割プーリ支持部先端にワイヤーケーブル４９の一端を取り付け、ケーブル４９の他端を籾摺揺動選別機の表壁体（カバー）３８の面内側に設けたレバー４７に取り付ける。こうして正面側からインペラ１１の回転数を調節できる。
こうして操作性が向上し、脱ぷ率（籾の外皮が剥離される率）を細かく操作できる。 8 is a partial front view (FIG. 8 (a)) and a partial rear side view (FIG. 8 (b)) of the case 46 of the impeller insertion portion 9, and a mounting portion of the split pulley operating lever 47 of the impeller 11. The figure seen from the arrow A direction of Fig.8 (a) which shows (FIG.8 (c)) is shown. The impeller rotary shaft 10 is provided with split pulleys 48 and 48 so that the rotational speed of the impeller rotary shaft 10 can be changed.
Further, one end of the wire cable 49 is attached to the tip of the split pulley support part, and the other end of the cable 49 is attached to a lever 47 provided on the inner surface of the front wall body (cover) 38 of the hulling and swinging sorter. Thus, the rotational speed of the impeller 11 can be adjusted from the front side.
In this way, the operability is improved, and the removal rate (the rate at which the hull skin is peeled) can be finely manipulated.
