Description

【0001】
【発明の属する技術分野】
本発明は、米や麦等の穀粒を粒径の大小によって選別し、小径の未熟粒を取り除いて整粒を得るようにした穀粒選別機に関する。
【0002】
【従来の技術】
従来の穀粒選別機においては、回転可能な選別筒の周面に、軸方向の幅よりも周方向の幅が大きな長孔状の選別孔を複数個穿設し、該選別筒内に供給された穀粒を、選別筒の長手方向に送りながら、前記選別孔から小径の未熟粒を漏出させて選別している。
【0003】
【発明が解決しようとする課題】
しかし、前記の構成では、選別孔の長孔短径より大きな径の砕粒は漏出することができなかった。
また、前記の如き砕粒は、選別孔に詰り易く、選別の効率を下げる原因となっていた。
そこで、簡単な構成で、上記の問題を解決することを課題とする。
【0004】
【課題を解決するための手段】
回転可能な選別筒1内に穀粒を供給し、該選別筒1の周面に設けた長孔状の選別孔2から、小径の未熟粒Aを漏出させて選別する穀粒選別機において、選別筒1の回転方向Dに対する選別孔2の長孔の始端部より後に、該長孔短径より大きな径を有する円状孔3を設けたことを特徴とする穀粒選別機の選別筒の構成とした。
【0005】
【発明の作用及び効果】
選別筒1内に供給された穀粒は、選別筒1の長手方向に送られながら、選別孔2により小径の未熟粒Aが選別筒1の外側へ漏出されて選別される。選別穀粒中に整粒Cがその長径の途中で折れることによって発生する砕粒Bが含まれていれば、該砕粒Bは長孔状の選別孔2に設けた、長孔部分の短径より大きな径を有する円孔3より漏出される。この円孔3は、選別筒1の回転方向Dに対する選別孔2の長孔の始端部より後に設けているので、前記砕粒Bは、始めに必ず選別孔2の長孔部分を通過すると共に該長孔部分で整列され、確実に円孔3にて漏出される。選別孔2の長孔部分で漏出されなかった整粒Cは、長径が円孔3の径より大きい為、円孔3から漏出されることがなく、選別筒1内を移送される。
以上のように、本発明の選別筒では、小径の未熟粒Aのみならず選別孔2の長孔短径より大きな径の砕粒Bも漏出することができるので、選別が確実であると共に、目詰りを起こし難く、効率的に選別することができる。
また、上記の効果は、選別筒1の回転方向Dに対する選別孔2の長孔の始端部より後に、該長孔短径より大きな径を有する円孔3を設けるだけで得られるので、構成が簡単である。
【0006】
【実施例】
次に、本発明を縦型穀粒選別機に実施した例を、図面を参照しながら説明する。
図1は、縦型穀粒選別機の全体側断面図であって、その構造は、以下に記述の如くしている。
四角筒状の外殻体4内の下部に基盤5を横架し、該基盤5上に受粒筒6を設置して、さらにその上に選別筒1を回転可能に装着している。そして、該受粒筒6と選別筒1内を貫通するラセン体7を回転可能に収嵌し、基盤5の下面に取り付けたギヤケース8によって前記選別筒1とラセン体7が互いに逆方向へ回転するようにしている。
9は、機体側部に装着したモータで、ベルト10によってギヤケース8に動力を伝動する。
【0007】
選別筒1の周面には、選別する穀粒の径に対応した短径を有する長孔状の選別孔2を複数列配列しており、該選別孔2は、選別筒1の回転方向Dに対する終端円孔3に形成している。
この円孔3の直径は、選別孔2の長孔部分の短径より大きくしているので、選別孔2は、おたまじゃくし状の形となる。
この選別孔2の長孔部分の短径と円孔3の直径の割合は、該直径が短径の1.5〜2.5倍程度に設定しており、実験により収集したデータから具体的な割合を説明すると、例えば短径が1.40mmの長孔に対し、直径が3.00mmの円孔3を設けた時が最も良い選別が成された。
【0008】
前記選別孔2を設けた範囲の選別筒1外周上側及び下側には、仕切板11、12を外殻体4に取着して設けており、該下側仕切板12で選別孔2から漏れ出す屑粒を受けて、外殻体4の外方へ向けて設けた取出シュート13から屑粒を外部へ取り出す。
また、上側仕切板11は、選別筒1の上側部に設けた整粒取出口14から放出される整粒Cを受けて、外殻体4の外側に突設した貯留タンク15内へ整粒Cを放出する。受粒筒6内には、外殻体4の下部に突設した供給シュート16を連通して、選別する穀粒を受け入れるようにしている。
17は、開口することで、外殻体4から選別筒1を上方へ抜き出し可能な上蓋で、蝶ねじ18によって取り付けている。
以上の構成で穀粒の選別作業を行うには、まず、供給シュート16から選別する穀粒を供給し、受粒筒6内へ該穀粒を流入する。すると、ラセン体7の回転により穀粒が上方へ運ばれるが、この時、穀粒は遠心力により外方へ案内され、ラセン体7を覆う選別筒1内周面に集積される。
【0009】
選別筒1内周面に集積される穀粒は、選別筒1の回転により該選別筒1の内周面に沿って、選別筒1の回転方向Dと逆に移動をし、図2(a)に示す如く、小径の未熟粒Aを選別孔2の長孔部分にて漏出する。
また、図2(b)、(c)に示す如く、この時漏出されない選別孔2の長孔短径より大きな径の穀粒は、前記選別孔2の長孔部分で整列され、選別孔2の円孔3部分へ移動し、従来の選別孔では目詰りを起こし易い砕粒Bを図3(a)に示す如く漏出する。整粒Cは、その長径が円孔3の直径より大きい為、図3(b)に示す如く円孔3から漏出されることがなく、選別筒1内に残ることになる。選別筒1内に残った整粒Cは、この後ラセン体7により、さらに上方へ運ばれて整粒取出口14から放出され、仕切板11にて受けられた後、貯留タンク15内へと送られる。選別孔2から選別筒1外へ漏出された小径の未熟粒Aと砕粒Bは、仕切板12にて受けられた後、取出シュート13から機体外部へ取り出される。
【0010】
このように、本発明の選別筒1では、目詰りを起こし易い砕粒Bを確実に漏出することができ、その構成が簡単であると共に操作も簡単である。
尚、本発明実施例において、選別孔2の円孔3位置は、選別筒1の回転方向Dに対する終端としたが、図4に示す如く長孔の中間部に設ける等、長孔の始端部より後ならばどこに設けてもよい。
さらに、該円孔3は、1つに限らず、図5に示す如く1つの選別孔2に複数個設けても良い。
また、円孔3を、楕円孔等にしても、円状の孔であれば同様の効果を奏する。
尚、請求の範囲の項に図面との対象と便利にする為に番号を記すが、この記入により本発明は添付図面の構造に限定されるものではない。

BACKGROUND OF THE INVENTION
The present invention relates to a grain sorter that sorts grains such as rice and wheat based on the particle size and removes immature grains having a small diameter to obtain a sized particle.
[0002]
[Prior art]
In a conventional grain sorter, a plurality of elongated sorting holes having a circumferential width larger than the axial width are formed on the circumferential surface of a rotatable sorting cylinder and supplied into the sorting cylinder. While feeding the processed grain in the longitudinal direction of the sorting cylinder, the small-diameter immature grain is leaked from the sorting hole and sorted.
[0003]
[Problems to be solved by the invention]
However, in the above configuration, crushed particles having a diameter larger than the long and short diameters of the sorting holes could not be leaked.
Further, the crushed particles as described above are easily clogged in the sorting holes, which causes a reduction in sorting efficiency.
Therefore, an object is to solve the above problem with a simple configuration.
[0004]
[Means for Solving the Problems]
In a grain sorter that feeds grains into a rotatable sorting cylinder 1 and sorts out small-diameter immature grains A from a long hole-shaped sorting hole 2 provided on the peripheral surface of the sorting cylinder 1, after the beginning of the long holes sorting holes 2 with respect to the rotational direction D of the sorting cylinder 1, sorting barrel grain sorter, characterized in that a circular hole 3 having a larger diameter than the long hole minor diameter The configuration was as follows.
[0005]
[Action and effect of the invention]
The grain supplied into the sorting cylinder 1 is sent out in the longitudinal direction of the sorting cylinder 1 and the immature grain A having a small diameter is leaked to the outside of the sorting cylinder 1 through the sorting hole 2 and sorted. If the crushed granule B generated by the sized particle C being broken in the middle of its major axis is included in the selected grain, the crushed granule B is formed from the minor axis of the long hole portion provided in the long hole-shaped sorting hole 2. It is leaked from the circular hole 3 having a larger diameter. Since this circular hole 3 is provided after the starting end of the long hole of the sorting hole 2 with respect to the rotation direction D of the sorting cylinder 1, the crushed granule B always passes through the long hole portion of the sorting hole 2 first. They are aligned at the long hole portion and reliably leak out at the circular hole 3. Sizing C that was not leaked in the long hole portion of the sorting holes 2, since the major diameter is greater than the diameter of the circular hole 3, without being leaked from the circular hole 3, it is transported through the screening cylinder 1.
As described above, in the sorting cylinder of the present invention, not only the small-diameter immature grains A but also the crushed grains B having a diameter larger than the long and short diameters of the sorting holes 2 can be leaked. It is hard to cause clogging and can be sorted efficiently.
Further, the above effect, after the long hole beginning of sorting holes 2 with respect to the rotational direction D of the sorting cylinder 1, so obtained only by providing a circular hole 3 having a larger diameter than the long hole short diameter, structure Is simple.
[0006]
【Example】
Next, the example which implemented this invention to the vertical grain sorter is demonstrated, referring drawings.
FIG. 1 is an overall side sectional view of a vertical grain sorter, and its structure is as described below.
A base 5 is horizontally mounted on the lower part of the rectangular cylindrical outer shell body 4, a granule 6 is installed on the base 5, and a sorting cylinder 1 is rotatably mounted thereon. Then, the granule 6 and the spiral body 7 passing through the sorting cylinder 1 are rotatably fitted, and the sorting cylinder 1 and the spiral body 7 are rotated in opposite directions by a gear case 8 attached to the lower surface of the base 5. Like to do.
A motor 9 is mounted on the side of the machine body and transmits power to the gear case 8 by the belt 10.
[0007]
On the peripheral surface of the sorting cylinder 1, a plurality of long hole-shaped sorting holes 2 having a minor axis corresponding to the diameter of the grain to be sorted are arranged, and the sorting holes 2 are arranged in the rotational direction D of the sorting cylinder 1. forming a termination on the circular hole 3 like for.
Since the diameter of the circular hole 3 is larger than the short diameter of the long hole portion of the sorting hole 2, the sorting hole 2 has a tadpole shape.
The ratio of the short diameter of the long hole portion of the sorting hole 2 to the diameter of the circular hole 3 is set to be about 1.5 to 2.5 times the short diameter. Explaining the ratio, for example, the best selection was made when the circular hole 3 having a diameter of 3.00 mm was provided for the long hole having a short diameter of 1.40 mm.
[0008]
Partition plates 11 and 12 are attached to the outer shell 4 on the upper and lower outer sides of the sorting cylinder 1 in the range where the sorting hole 2 is provided. The lower partition plate 12 extends from the sorting hole 2. In response to the leaked waste particles, the waste particles are taken out from the take-out chute 13 provided toward the outside of the outer shell body 4.
Further, the upper partition plate 11 receives the sized particle C discharged from the sized particle outlet 14 provided on the upper side of the sorting cylinder 1 and sized into the storage tank 15 protruding from the outer shell 4. C is released. A feed chute 16 projecting from the lower part of the outer shell body 4 is communicated with the granule 6 so as to receive the grain to be selected.
Reference numeral 17 denotes an upper lid that can be opened to extract the sorting cylinder 1 upward from the outer shell body 4, and is attached by a thumbscrew 18.
In order to perform the grain sorting operation with the above configuration, first, the grain to be sorted is supplied from the supply chute 16, and the grain flows into the receiving cylinder 6. Then, the grains are carried upward by the rotation of the spiral body 7. At this time, the grains are guided outward by centrifugal force and accumulated on the inner peripheral surface of the sorting cylinder 1 covering the spiral body 7.
[0009]
The grains accumulated on the inner peripheral surface of the sorting cylinder 1 move along the inner peripheral surface of the sorting cylinder 1 by the rotation of the sorting cylinder 1 in the direction opposite to the rotation direction D of the sorting cylinder 1, and FIG. ), The small-diameter immature grains A are leaked out at the long hole portions of the sorting holes 2.
Further, as shown in FIGS. 2B and 2C, grains having a diameter larger than the long and short diameter of the sorting hole 2 that is not leaked at this time are aligned in the long hole portion of the sorting hole 2 and are sorted. As shown in FIG. 3 (a), the crushed granule B that moves to the circular hole 3 portion and easily clogs in the conventional sorting hole leaks. Since the long diameter of the sized particle C is larger than the diameter of the circular hole 3, it is not leaked from the circular hole 3 as shown in FIG. The sized particles C remaining in the sorting cylinder 1 are then transported further upward by the helical body 7, discharged from the sized particle outlet 14, received by the partition plate 11, and then into the storage tank 15. Sent. Small-diameter immature grains A and crushed grains B leaked from the sorting hole 2 to the outside of the sorting cylinder 1 are received by the partition plate 12 and then taken out from the take-out chute 13 to the outside of the machine body.
[0010]
As described above, in the sorting cylinder 1 of the present invention, the crushed particles B that are likely to be clogged can be surely leaked, and the configuration thereof is simple and the operation is also simple.
In the embodiment of the present invention, the position of the circular hole 3 of the sorting hole 2 is the end of the sorting cylinder 1 with respect to the rotation direction D. However, as shown in FIG. It may be installed anywhere later.
Further, the number of the circular holes 3 is not limited to one, and a plurality of circular holes 3 may be provided in one sorting hole 2 as shown in FIG.
Moreover , even if the circular hole 3 is an elliptical hole or the like, the same effect can be obtained if it is a circular hole.
It should be noted that although numbers are given in the claims section for the purpose of convenience with the drawings, the present invention is not limited to the structure of the attached drawings by this entry.
