Description

横型穀類脱皮装置Horizontal grain molting device
　本発明は、穀類の表皮を除去する横型穀類脱皮装置に関する。 The present invention relates to a horizontal cereal molting device that removes the epidermis of cereals.
　従来、穀類の表皮を除去する装置として、円筒形のスクリーンの内側に精穀室を形成し、精穀室の内部に回転する砥石ロールを設けた、穀類脱皮装置が知られている（特許文献１参照）。さらに、この穀類脱皮装置は、精穀室の軸方向の一端側に穀類の供給口が形成され、軸方向の他端側には開閉することが可能な蓋を有する穀類の排出口が形成されている。そして穀類脱皮装置は、供給口が上になり、排出口が下になるよう傾斜して設置される。
　上記した傾斜型の穀類脱皮装置では、排出口を閉じた状態で、供給口から供給された穀類が重力により精穀室を通過する。そして、穀類は、精穀室を通過する間に砥石ロールの回転によって攪拌されながら研削され、表皮が除去される。 Conventionally, as a device for removing the epidermis of cereals, a cereal molting device is known in which a cereal chamber is formed inside a cylindrical screen and a rotating grindstone roll is provided inside the cereal chamber (Patent Documents). 1). Further, in this cereal molting device, a grain supply port is formed on one end side in the axial direction of the grain milling chamber, and a grain discharge port having a lid that can be opened and closed is formed on the other end side in the axial direction. ing. The cereal molting device is installed at an angle so that the supply port is on the top and the discharge port is on the bottom.
In the inclined type grain molting device described above, the grain supplied from the supply port passes through the grain mill by gravity with the discharge port closed. Then, the cereals are ground while being agitated by the rotation of the grindstone roll while passing through the grain milling chamber, and the epidermis is removed.
　しかし、上記した傾斜型の穀類脱皮装置では、精穀室に供給された穀類が、排出口側に溜まり、砥石ロールの排出口側の部分のみで穀類が研削されることがあった。その結果、穀類の脱皮効率が低下したり、砥石ロールが局部的に早く磨耗することがあった。
　さらに、精穀室の排出口付近に多量の穀類が充満するので、排出口付近の圧力が高まって穀類が砕かれ、砕粒が増加することがある。 However, in the above-mentioned inclined type grain molting device, the grain supplied to the grain milling chamber may be accumulated on the discharge port side, and the grain may be ground only on the discharge port side of the grindstone roll. As a result, the dehulling efficiency of cereals may decrease, and the grindstone roll may wear locally and quickly.
Further, since a large amount of grains are filled in the vicinity of the discharge port of the grain milling chamber, the pressure in the vicinity of the discharge port increases, the grains may be crushed, and the number of crushed grains may increase.
　特許文献２には、円筒状のスクリーン及び研削ロールをほぼ水平に設置した横形研削式精穀機が開示されている。
　上記した横形研削式精穀機は、スクリーンが周方向に分割しており、分割された各スクリーンは研削ロールの軸芯から偏心している。さらに、研削ロールの回転方向の上手側における研削ロール外周面とスクリーンとの距離を大きくし、回転方向の下手側に向かうにしたがって、徐々に研削ロール外周面とスクリーンとの距離を小さくしている。このような構成により、研削ロール外周面とスクリーンとの距離が小さくなり、横形研削式精穀機は、穀類の密度が高い滞留部分で穀類を脱皮し、その後、研削ロール外周面とスクリーンとの距離が広がった部分に達した穀類を、旋回させながら研削ロールの全面で研削することができる。このため、研削ロールを水平に設置することで、研削ロールの局部的な磨耗を抑制することができ、砕粒を少なくすることができる。 Patent Document 2 discloses a horizontal grinding type grain mill in which a cylindrical screen and a grinding roll are installed substantially horizontally.
In the above-mentioned horizontal grinding type grain mill, the screen is divided in the circumferential direction, and each divided screen is eccentric from the axis of the grinding roll. Further, the distance between the outer peripheral surface of the grinding roll and the screen on the upper side in the rotation direction of the grinding roll is increased, and the distance between the outer peripheral surface of the grinding roll and the screen is gradually decreased toward the lower side in the rotation direction. .. With such a configuration, the distance between the outer peripheral surface of the grinding roll and the screen is reduced, and the horizontal grinding type grain mill removes the grain at the retention portion where the grain density is high, and then the outer peripheral surface of the grinding roll and the screen Grains that have reached the widened part can be ground on the entire surface of the grinding roll while swirling. Therefore, by installing the grinding roll horizontally, it is possible to suppress local wear of the grinding roll and reduce crushed particles.

　しかし、上記特許文献２に記載の横形研削式精穀機では、分割された各スクリーンの両側の締結部に多数の長穴が形成されており、これら長穴にそれぞれ通した固定ボルトによってフラップ台に固定されている。そして、穀類の粒径等に応じて研削ロールと各スクリーンの距離を調節する際は、両側の固定ボルトを緩めてスクリーンを移動させるので、両側及び軸方向の移動量を均等にしなければ、スクリーンの湾曲形状が変形してしまうおそれがあった。さらに、上記したスクリーンを調節する作業では、全ての固定ボルトを締めなおさなければならないため、調整作業に手間がかかることがあった。
　本発明が解決しようとする課題は、穀類の砕粒が発生しにくく、砥石ロールの局部的な磨耗を抑制でき、しかも、砥石ロールの外周面とスクリーンとの間の距離を簡単に調整することが可能な、横型穀類脱皮装置を提供することにある。 However, in the horizontal grinding type grain mill described in Patent Document 2, a large number of elongated holes are formed in the fastening portions on both sides of each of the divided screens, and the flap base is formed by the fixing bolts passed through the elongated holes. It is fixed to. When adjusting the distance between the grinding roll and each screen according to the grain size of the grain, the fixing bolts on both sides are loosened to move the screen. Therefore, the screen must be moved evenly on both sides and in the axial direction. There was a risk that the curved shape of the would be deformed. Further, in the work of adjusting the screen described above, all the fixing bolts must be retightened, which may take time and effort for the adjustment work.
The problem to be solved by the present invention is that grain crushing is less likely to occur, local wear of the grindstone roll can be suppressed, and the distance between the outer peripheral surface of the grindstone roll and the screen can be easily adjusted. It is to provide a possible horizontal cereal molting device.

The horizontal cereal molting device according to any one of claims 1 to 7, which is characteristic.
　本発明によれば、軸方向に直交する断面において、精穀室の一部を狭くすることができる。これにより、この狭い部分に穀類を滞留させて砥石ロールによる確実な脱皮を行うことができる。さらに、穀類が滞留部分を通過した後は、砥石ロールの回転で旋回させながら、砥石ロールの全面で穀類を研削するため、研削効率がよく、圧力の高まりすぎを防いで砕粒を減少させることができる。加えて、砥石ロールが局部的に磨耗することを防ぐことができる。
　さらに、スクリーンフレームを移動するだけで、スクリーン全体が砥石ロールに対して偏心するため、スクリーンの湾曲形状が変形することがない。したがって、スクリーンの湾曲形状を変形させることなく、スクリーンと砥石フレームの外周面との間の幅寸法を簡単に調整することができる。
　さらに、穀類の粒径、穀類の種類等に応じて、スクリーンと砥石ロールの外周面との間の距離を調整できるので、汎用性が高い。 According to the present invention, a part of the grain mill can be narrowed in a cross section orthogonal to the axial direction. As a result, cereals can be retained in this narrow portion and dehulling can be performed reliably with a grindstone roll. Furthermore, after the grain has passed through the stagnant portion, the grain is ground on the entire surface of the grindstone roll while being swirled by the rotation of the grindstone roll, so that the grinding efficiency is good, the pressure does not rise too much, and the crushed grains can be reduced. it can. In addition, it is possible to prevent the grindstone roll from being locally worn.
Further, since the entire screen is eccentric with respect to the grindstone roll simply by moving the screen frame, the curved shape of the screen is not deformed. Therefore, the width dimension between the screen and the outer peripheral surface of the grindstone frame can be easily adjusted without deforming the curved shape of the screen.
Further, the distance between the screen and the outer peripheral surface of the grindstone roll can be adjusted according to the grain size of the grain, the type of the grain, and the like, so that the versatility is high.
　スクリーンフレームを左右に位置調節できるようにすれば、砥石ロールの回転方向において、穀類が落下しながら流れる部分を狭くして精穀室に滞留しやすくし、研削ムラを少なくすることができる。 If the position of the screen frame can be adjusted to the left and right, in the rotation direction of the grindstone roll, the part where the grain flows while falling is narrowed so that it easily stays in the grain milling chamber, and grinding unevenness can be reduced.
　スクリーンフレームを上下に位置調節できるようにすれば、穀類が滞留しづらい精穀室の上部を狭くすることができる。これにより、精穀室の上部においても穀類に圧力がかかるため、穀類の脱皮が効率的に行われる。さらに、精穀室の上部と下部との圧力差が小さくなる。その結果、穀類の研削ムラが少なくなるだけでなく、落下した大量の穀類が精穀室の下部に詰まって、排出口方向へのスムーズな送りを妨げるおそれもなくなり、高圧によって砕粒が発生することも防止できる。 If the position of the screen frame can be adjusted up and down, the upper part of the grain processing chamber where grains are difficult to stay can be narrowed. As a result, pressure is applied to the cereals even in the upper part of the cereal chamber, so that the cereals are efficiently molted. In addition, the pressure difference between the upper and lower parts of the grain processing chamber becomes smaller. As a result, not only the uneven grinding of grains is reduced, but also a large amount of dropped grains are not likely to be clogged in the lower part of the grain mill and hinder smooth feeding toward the discharge port, and crushed grains are generated by high pressure. Can also be prevented.
　精穀室の狭い部分に抵抗フラップを突出させれば、狭い部分を通過する穀類を抵抗フラップが遮って、砥石ロールの回転方向の上流側に穀類が滞留する時間を長くすることができる。これにより、研削効率がさらに向上する。 If the resistance flap is projected into the narrow part of the grain mill, the resistance flap blocks the grains passing through the narrow part, and the time for the grains to stay upstream in the rotation direction of the grindstone roll can be lengthened. As a result, the grinding efficiency is further improved.
　砥石ロールの回転方向において、穀類が落下して流れる部分に抵抗フラップを設けることで、穀類を回転させながら搬送させる際に、精穀室に穀類を滞留させやすくなり、効率的な穀類の脱皮が可能となる。 By providing a resistance flap in the part where the grain falls and flows in the direction of rotation of the grindstone roll, it becomes easier for the grain to stay in the grain mill when the grain is transported while rotating, and efficient grain dehulling is possible. It will be possible.
　抵抗フラップの突出量を機体の外側から調整可能とすることにより、稼動中であっても、穀類の粒径等に応じて抵抗フラップの突出量を調整できる。 By making it possible to adjust the amount of protrusion of the resistance flap from the outside of the machine body, the amount of protrusion of the resistance flap can be adjusted according to the particle size of grains and the like even during operation.
　精穀室において穀類が落下して流れる部分や、穀類が滞留しづらい上部を狭くすることで、均等に穀類に圧力がかかる。これにより、排出口の蓋の錘による排出部付近の負荷が必要なくなる。
その結果、蓋が穀類を移送する力によって簡単に開き、精穀室内の穀類に局部的に高い圧力が加わらないので、砕粒も発生しにくい。 Pressure is evenly applied to the grains by narrowing the part where the grains fall and flow in the grain mill and the upper part where the grains are hard to stay. This eliminates the need for a load near the discharge portion due to the weight of the lid of the discharge port.
As a result, the lid is easily opened by the force of transferring cereals, and since high pressure is not locally applied to the cereals in the grain milling chamber, crushing is less likely to occur.

A through hole 8 is formed in the central portion of the partition wall 7a and the support plates 7b, 7c, 7d.
　砥石ロール１８は、機体２の内部に回転可能に固定されている。砥石ロール１８には、穀類供給ホッパ３の下方に設置される図示しない螺旋ロールが連結されている。螺旋ロールは、隔壁７ａに形成された貫通孔８を通して駆動室２ｂ内のモータと連結され、回転可能に固定されている。そして、モータの駆動により螺旋ロール及び砥石ロール１８が図８及び図９に示すように時計回りに回転する。 The grindstone roll 18 is rotatably fixed inside the machine body 2.

　スクリーン１０の左右両側部には、張出し片１０ａが形成されている。スクリーン１０の内周面には、穀類供給ホッパ３から精穀室１９に投入された穀類を排出口４に向かって送るための螺旋状のガイドプレート１２が設けられている。ガイドプレート１２は、スクリーン１０の外周からボルトによって取り付けられている。 As shown in FIGS. 4 to 6, the screen 10 is formed of a porous metal plate and has a semicircular arc-shaped cross section in which a cylinder is divided into two by a diameter portion. Then, the upper screen 10 and the lower screen 10 having a semicircular arc shape of the screen 10 are combined to form a cylindrical shape.
Overhanging pieces 10a are formed on both the left and right sides of the screen 10. On the inner peripheral surface of the screen 10, a spiral guide plate 12 for sending the grains input from the grain supply hopper 3 into the grain mill 19 toward the discharge port 4 is provided. The guide plate 12 is attached by bolts from the outer periphery of the screen 10.
　スクリーンフレーム１１は、上部のスクリーン１０及び下部のスクリーン１０それぞれの前端部と後端部、及び、前端部と後端部の中間部に取り付けられる半円形状の内枠１１ａを備えている。さらに、軸方向に延びて、各内枠１１ａの左右の端部、及び、その中間部を連結する連結枠１１ｂを備えている。図６に示されるように、スクリーン１０の前端部と後端部に設けられた内枠１１ａには、円環状の外枠１１ｃが取り付けられている。
　外枠１１ｃの内径は、スクリーン１０の内径とほぼ同じであり、外枠１１ｃの外径は内枠１１ａの外径より大きく形成されている。 The screen frame 11 includes a semicircular inner frame 11a attached to the front end portion and the rear end portion of the upper screen 10 and the lower screen 10 respectively, and an intermediate portion between the front end portion and the rear end portion. Further, it is provided with a connecting frame 11b extending in the axial direction to connect the left and right ends of each inner frame 11a and the intermediate portion thereof. As shown in FIG. 6, an annular outer frame 11c is attached to the inner frame 11a provided at the front end portion and the rear end portion of the screen 10.
The inner diameter of the outer frame 11c is substantially the same as the inner diameter of the screen 10, and the outer diameter of the outer frame 11c is formed to be larger than the outer diameter of the inner frame 11a.
　各内枠１１ａの左右の端部に設けた連結枠１１ｂと、スクリーン１０の張出し片１０ａとをボルト等で止めることにより、スクリーンフレーム１１がスクリーン１０に固定される。上部のスクリーン１０及びスクリーンフレーム１１と、下部のスクリーン１０及びスクリーンフレーム１１とは、連結枠１１ｂ及び張出し片１０ａを介して連結されている。このようにして、スクリーン１０はスクリーンフレーム１１によって円筒形状を維持するように固定される。上部のスクリーン１０及びスクリーンフレーム１１と、下部のスクリーン１０及びスクリーンフレーム１１の右側部分は、後述する抵抗フラップ１４を支持するためのフラップフレーム１３を挟んで固定されている。 The screen frame 11 is fixed to the screen 10 by fixing the connecting frames 11b provided at the left and right ends of each inner frame 11a and the overhanging piece 10a of the screen 10 with bolts or the like. The upper screen 10 and the screen frame 11 and the lower screen 10 and the screen frame 11 are connected via the connecting frame 11b and the overhanging piece 10a. In this way, the screen 10 is fixed by the screen frame 11 so as to maintain a cylindrical shape. The upper screen 10 and the screen frame 11 and the right side portion of the lower screen 10 and the screen frame 11 are fixed with the flap frame 13 for supporting the resistance flap 14 described later interposed therebetween.
　本実施形態では、円筒形状に組み立てられた２組のスクリーン１０及びスクリーンフレーム１１が、図６に示されるように、同軸上に連続して設置されている。互いに向き合うスクリーンフレーム１１の外枠１１ｃには、左右両側にそれぞれ取っ手１６が設けられる。 In this embodiment, two sets of screens 10 and screen frames 11 assembled in a cylindrical shape are continuously installed coaxially as shown in FIG. Handles 16 are provided on both the left and right sides of the outer frame 11c of the screen frames 11 facing each other.
　図７に示すように、同軸上に設置される２組のスクリーン１０及びスクリーンフレーム１１は、機体２の軸方向の中間部分に設けられた支持プレート７ｃを挟んで配置される。機体２の支持プレート７ｂ，７ｃ，７ｄには、スクリーンフレーム１１の外枠１１ｃがそれぞれ配置される。
　そして、スクリーンフレーム１１の外枠１１ｃと支持プレート７ｂ，７ｃ，７ｄは、左右両側の上部と下部において固定される。外枠１１ｃ及び支持プレート７ｂ，７ｃ，７ｄの内のいずれか一方には、図８に示されるような左右方向に長い長孔９が形成され、長孔９を貫通するボルト１７によって、外枠１１ｃと支持プレート７ｂ，７ｃ，７ｄが固定されている。本実施形態では、長孔９は、支持プレート７ｂ、７ｄに取り付けられる外枠１１ｃと、支持プレート７ｃに設けられている。 As shown in FIG. 7, the two sets of screens 10 and screen frames 11 installed coaxially are arranged so as to sandwich a support plate 7c provided at an intermediate portion in the axial direction of the machine body 2. The outer frame 11c of the screen frame 11 is arranged on the support plates 7b, 7c, 7d of the machine body 2, respectively.
The outer frame 11c of the screen frame 11 and the support plates 7b, 7c, 7d are fixed at the upper and lower portions on both the left and right sides. An elongated hole 9 that is long in the left-right direction as shown in FIG. 8 is formed in one of the outer frame 11c and the support plates 7b, 7c, and 7d, and the outer frame is formed by a bolt 17 that penetrates the elongated hole 9. 11c and support plates 7b, 7c, 7d are fixed. In the present embodiment, the elongated holes 9 are provided in the outer frame 11c attached to the support plates 7b and 7d and the support plate 7c.
　このような構成により、ボルト１７を緩めて、長孔９に沿って左右方向に外枠１１ｃを支持プレート７ｂ、７ｃ、７ｄに対して移動させることが可能となる。そして、スクリーン１０とともにスクリーンフレーム１１を、スクリーン１０の円筒形状を保ったまま移動させることができる。したがって、スクリーンの円筒形状を変形させることなく、スクリーン１０の軸心の位置を、砥石ロール１８の軸心に対して左右方向に調節することができ、スクリーン１０と砥石ロール１８の外周面との間の幅寸法を調整することが可能となる。スクリーン１０の移動可能な距離は左右にそれぞれ５ｍｍ程度としている。
　スクリーンフレーム１１及びスクリーン１０を移動する際は、ボルト１７を緩めた状態で、外枠１１ｃに設けた取っ手１６を引っ張ることにより、簡単にスクリーンフレーム１１及びスクリーン１０を左右に移動させることができる。 With such a configuration, the bolt 17 can be loosened to move the outer frame 11c in the left-right direction along the elongated hole 9 with respect to the support plates 7b, 7c, and 7d. Then, the screen frame 11 can be moved together with the screen 10 while maintaining the cylindrical shape of the screen 10. Therefore, the position of the axial center of the screen 10 can be adjusted in the left-right direction with respect to the axial center of the grindstone roll 18 without deforming the cylindrical shape of the screen, and the screen 10 and the outer peripheral surface of the grindstone roll 18 can be adjusted. It is possible to adjust the width dimension between them. The movable distance of the screen 10 is about 5 mm on each side.
When moving the screen frame 11 and the screen 10, the screen frame 11 and the screen 10 can be easily moved to the left and right by pulling the handle 16 provided on the outer frame 11c with the bolts 17 loosened.
　図８に示すように、ボルト１７が長孔９の中央部に挿通されているときは、砥石ロール１８の中心軸とスクリーン１０の中心軸が同じになる。しかし、図９に示すように、スクリーンフレーム１１を左へ移動させてボルト１７が長孔９の右端に挿通された状態で固定すると、スクリーン１０と砥石ロール１８の外周面との距離（精穀室１９の幅）が、右側で狭く、左側で広くなる。
　このように、精穀室１９の右側を狭くして、砥石ロール１８を時計回りさせると、穀類が回転しながら搬送され、精穀室１９の狭い部分に滞留しやすくなる。これにより、効率的な脱皮が可能となる。 As shown in FIG. 8, when the bolt 17 is inserted through the central portion of the elongated hole 9, the central axis of the grindstone roll 18 and the central axis of the screen 10 are the same. However, as shown in FIG. 9, when the screen frame 11 is moved to the left and the bolt 17 is fixed while being inserted into the right end of the elongated hole 9, the distance between the screen 10 and the outer peripheral surface of the grindstone roll 18 (refined grain). The width of the chamber 19) is narrow on the right side and wide on the left side.
When the right side of the grain mill 19 is narrowed and the grindstone roll 18 is rotated clockwise in this way, the grains are transported while rotating, and tend to stay in the narrow portion of the grain chamber 19. This enables efficient molting.
　本実施形態では、スクリーン１０と砥石ロール１８の外周面との距離が狭くなる精穀室１９の右側において、上部のスクリーン１０と下部のスクリーン１０との間に、精穀室１９に向かって突出する抵抗フラップ１４が、軸方向に沿って設置される。
　抵抗フラップ１４は、精穀室１９内の穀類を砕かないように、ゴム等の柔らかい素材によって構成され、その径方向外側面の複数個所には操作ボルト１５が取り付けられている。操作ボルト１５は側部カバー２ａを貫通して機体２の外部に露出し、その先端にはハンドル６が設けられる。 In the present embodiment, on the right side of the grain mill 19 where the distance between the screen 10 and the outer peripheral surface of the grindstone roll 18 is narrowed, the protrusion toward the grain chamber 19 is between the upper screen 10 and the lower screen 10. The resistance flap 14 is installed along the axial direction.
The resistance flap 14 is made of a soft material such as rubber so as not to crush the grains in the grain mill 19, and operating bolts 15 are attached to a plurality of locations on the outer surface in the radial direction thereof. The operation bolt 15 penetrates the side cover 2a and is exposed to the outside of the machine body 2, and a handle 6 is provided at the tip thereof.
　操作ボルト１５は、フラップフレーム１３に螺合され、ハンドル６を回転操作することにより、抵抗フラップ１４の精穀室１９における突出量を調整できるようになっている。
　フラップフレーム１３は、スクリーン１０及びスクリーンフレーム１１に固定されているので、スクリーンフレーム１１を左右に移動させると、抵抗フラップ１４も移動することがで、更に穀類の脱皮を効率的に行うことが可能となる。 The operation bolt 15 is screwed into the flap frame 13, and the amount of protrusion of the resistance flap 14 in the grain chamber 19 can be adjusted by rotating the handle 6.
Since the flap frame 13 is fixed to the screen 10 and the screen frame 11, when the screen frame 11 is moved to the left or right, the resistance flap 14 can also be moved, so that the grain can be moulted more efficiently. It becomes.
　横型穀類脱皮装置１を用いて穀類の脱皮を行う際は、スクリーン１０を左側へ移動させて、スクリーン１０と砥石ロール１８の外周面との間の距離を右側で狭く、左側で広くする。そして、砥石ロール１８を時計回りに回転させ、穀類供給ホッパ３から原料となる穀類を精穀室１９へ供給する。スクリーン１０の左右方向の移動量及び抵抗フラップ１４の突出量は、穀類の粒形やサイズ、表皮の硬さ等に応じて調整する。 When peeling grains using the horizontal grain peeling device 1, the screen 10 is moved to the left side, and the distance between the screen 10 and the outer peripheral surface of the grindstone roll 18 is narrowed on the right side and widened on the left side. Then, the grindstone roll 18 is rotated clockwise to supply the grain as a raw material from the grain supply hopper 3 to the grain mill 19. The amount of movement of the screen 10 in the left-right direction and the amount of protrusion of the resistance flap 14 are adjusted according to the grain shape and size of the grain, the hardness of the epidermis, and the like.
　精穀室１９へ投入された穀類は、砥石ロール１８の回転により左側下方へ落下する。精穀室１９の右側部は狭くなっており、しかも抵抗フラップ１４が突出しているので、抵抗フラップ１４の上方に穀類が滞留し、砥石ロール１８によって確実に研削される。
　抵抗フラップ１４を通過した穀類は、砥石ロール１８の回転によって旋回しながら砥石ロール１８の全面で研削され、スクリーン１０のガイドプレート１２によって排出口４に向かって移送される。 The grains thrown into the grain mill 19 fall to the lower left side due to the rotation of the grindstone roll 18. Since the right side portion of the grain mill 19 is narrow and the resistance flap 14 protrudes, grains stay above the resistance flap 14 and are reliably ground by the grindstone roll 18.
The grain that has passed through the resistance flap 14 is ground on the entire surface of the grindstone roll 18 while being swirled by the rotation of the grindstone roll 18, and is transferred toward the discharge port 4 by the guide plate 12 of the screen 10.
　研削されながら移送される穀類は排出口４に達するまでに精穀され、穀類が蓋５を押し開けることによって排出口４から排出される。スクリーン１０と砥石ロール１８が水平に設けられ、精穀室１９の中では穀類に均等に圧力がかかる。これにより、排出口４の蓋５に錘を設けなくても、蓋５は穀類が移送される力によって簡単に開く。さらに、精穀室１９内の穀類に局部的に高い圧力が加わらないので、砕粒も発生しにくい。
　除去された表皮は、スクリーン１０に形成された孔を通して精穀室１９の外部に排出され、機体２の底部から排出される。 The grains transferred while being ground are refined by the time they reach the discharge port 4, and the grains are discharged from the discharge port 4 by pushing the lid 5 open. The screen 10 and the grindstone roll 18 are provided horizontally, and pressure is evenly applied to the grains in the grain mill 19. As a result, even if the lid 5 of the discharge port 4 is not provided with a weight, the lid 5 can be easily opened by the force to which the grains are transferred. Further, since a high pressure is not locally applied to the grains in the grain mill 19, crushing is less likely to occur.
The removed epidermis is discharged to the outside of the grain mill 19 through the holes formed in the screen 10, and is discharged from the bottom of the machine body 2.
　〔第２の実施形態〕
　以下に、本発明の第２の実施形態について、図１０及び図１１に基づいて説明する。なお、第１の実施形態と同様の部分については説明を省略し、主に第１の実施形態と異なる部分について説明する。 [Second Embodiment]
The second embodiment of the present invention will be described below with reference to FIGS. 10 and 11. The description of the same parts as those of the first embodiment will be omitted, and the parts different from those of the first embodiment will be mainly described.
　第２の実施形態では、スクリーンフレーム１１の外枠１１ｃ及び支持プレート７ｂ，７ｃ，７ｄのいずれか一方には、図１０に示されるように上下方向に沿って長孔９を形成している。図示されている例では、支持プレート７ｂに取り付けられる外枠１１ｃに長孔９を形成している。これにより、スクリーンフレーム１１及びスクリーン１０の位置を上下に調整することができる。 In the second embodiment, elongated holes 9 are formed in one of the outer frame 11c and the support plates 7b, 7c, and 7d of the screen frame 11 along the vertical direction as shown in FIG. In the illustrated example, the elongated hole 9 is formed in the outer frame 11c attached to the support plate 7b. Thereby, the positions of the screen frame 11 and the screen 10 can be adjusted up and down.
　図１０に示すように、長孔９の中央部にボルト１７を挿通させ、スクリーン１０の軸心と砥石ロール１８の軸心とを一致させた状態から、図１１に示すように、スクリーンフレーム１１及びスクリーン１０を下方に移動して、長孔９の上端部でボルト１７による固定を行う。これにより、スクリーン１０の上部と砥石ロール１８の外周面との距離よりも、スクリーン１０の下部と砥石ロール１８の外周面との距離の方が広くなる。
　このようにすれば、穀類が滞留しづらい精穀室１９の上部を狭くすることができ、穀類に圧力をかけることができる。したがって、精穀室１９の上部においても穀類の脱皮が効率的に行われる。さらに、精穀室１９の上部と精穀室１９の下部における穀類に対する圧力差が小さくなる。この結果、穀類の研削ムラが少なくなり、さらに、落下した大量の穀類が精穀室１９の下部に詰まったり、穀類に対する圧力が高くなって砕粒が発生するのを防止できる。 As shown in FIG. 10, a bolt 17 is inserted through the central portion of the elongated hole 9, and the axis of the screen 10 and the axis of the grindstone roll 18 are aligned with each other. Then, as shown in FIG. 11, the screen frame 11 And the screen 10 is moved downward to fix it with a bolt 17 at the upper end of the elongated hole 9. As a result, the distance between the lower part of the screen 10 and the outer peripheral surface of the grindstone roll 18 is wider than the distance between the upper part of the screen 10 and the outer peripheral surface of the grindstone roll 18.
By doing so, it is possible to narrow the upper part of the grain mill 19 where the grains are hard to stay, and it is possible to apply pressure to the grains. Therefore, the cereals are efficiently molted even in the upper part of the grain mill 19. Further, the pressure difference between the upper part of the grain mill 19 and the lower part of the grain chamber 19 with respect to the cereal becomes smaller. As a result, uneven grinding of cereals is reduced, and it is possible to prevent a large amount of fallen cereals from clogging the lower part of the grain mill 19 or increasing pressure on the cereals to generate crushed grains.
　本実施形態では、砥石ロール１８が時計回りをする場合に、抵抗フラップ１４を精穀室１９の右側に設けているので、穀類の回転搬送時に精穀室１９に穀類を滞留させやすくなり、効率的な脱皮が可能となる。 In the present embodiment, when the grindstone roll 18 rotates clockwise, the resistance flap 14 is provided on the right side of the grain milling chamber 19, so that the grain can be easily retained in the grain milling chamber 19 during the rotary transportation of the grain, which is efficient. It is possible to remove the skin.
