Description

【０００１】
【産業上の利用分野】
この発明は、選別円筒の回転で壷穴が小粒の玄米を大粒の籾米よりも高く汲み上げて分離する回転選別装置を備えた円筒式籾摺選別機に用いるものである。
【０００２】
【従来の技術】
この円筒式籾摺選別機は、選別する米粒の大小や長短などの差に応じて、選別円筒の壷穴の大きさが異なるものに取り替えて、選別作業をしたり、また、長期間使用すると、壷穴にほこりが詰って選別性能が低下するので、定期的に清掃するために、選別円筒を選別ケ−スから取り外す必要がある。このような従来技術として、特開平３−１７８３７８号公報がある。
【０００３】
【発明が解決しようとする課題】
前記従来技術にあつては、横軸回りに回転している選別円筒を選別ケ−スから取り外す時に、選別円筒内部の玄米受樋や移送ラセンを選別ケ−スに取り付けたままで、選別円筒だけを取り外しできる点で便利である。しかし、選別円筒の前側の円筒フランジと、駆動ロ−ラ軸に取り付けられている駆動ロ−ラとの関係に十分な配慮がされてなく、着脱の際に選別円筒の前側の円筒フランジと前側の駆動ロ−ラとの位置決めが円滑に出来ないという問題点があつた。そこで、この発明は、このような問題点を解決しようとするものである。
【０００４】
【課題を解決するための手段】
この発明は、このような従来技術のもつ問題点を解決するために、次の技術的手段を講じた。即ち、この発明は、内周面に多数の壷穴４，４，…が設けられていて前後方向に長く且つ後側を選別始端側とし前側を選別終端側として横軸回りに回転する選別円筒５と、選別円筒５の前後両外周部を下から支える４個の駆動ロ−ラ７，７，…と、選別円筒５を被っていて脱ぷ装置２の後方に設けられている選別ケ−ス８と、選別円筒５内においてその長手方向に沿って壷穴４，４，…で汲み上げられた玄米を受け且つ受けられた玄米を選別円筒５の後側の選別始端側から前側の選別終端側に玄米ラセン２５で移送して取り出す玄米受樋２６と、該玄米受樋２６に並行に設けられていて被選別穀粒を選別円筒５の前側の選別終端側から後側の選別始端側へ供給ラセン２７で移送する供給樋２８とを備えた回転式籾摺選別機であつて、前記選別ケ−ス８における脱ぷ装置２に近い前側の前板８ａには前記玄米受樋２６・玄米ラセン２５及び供給樋２８・供給ラセン２７の前端部が取り付けられると共に、それらの後端部が支持板３０に連結支持されこの支持板３０を選別ケ−ス８における脱ぷ装置２から遠い後側の後板１１に着脱自在に支持される構成とし、この後板１１を選別ケ−ス８，玄米受樋２６・玄米ラセン２５及び供給樋２８・供給ラセン２７の後端部から分離すことにより、玄米受樋２６，玄米ラセン２５及び供給樋２８・供給ラセン２７の前端部が前板８ａに取り付けられたままの状態で選別円筒５だけが後方に引き抜かれるように構成したものにおいて、前記選別円筒５の前後両外周部に設けられている円筒フランジ６，６を、前記選別円筒５の軸心方向に沿った左右の駆動ロ−ラ軸２１，２１の前後両端部に夫れ夫れ取り付けている前後の駆動ロ−ラ７，７，…で回転自在に支持し、前記左右の駆動ロ−ラ軸２１，２１の前側の駆動ロ−ラ７，７の後側には、後側ほど大径となる前側円錐部３２，該前側円錐部３２の後端に接続していて後側が小径の後側円錐部３３からなる案内カラ−３１を、前側の駆動ローラ７、７の後端面から前側円錐部３２の後端部までの前後長さを上記円筒フランジ６の前後長さよりも短く構成したことを特徴とする回転式籾摺選別機の選別円筒着脱装置の構成としたものである。
【０００５】
【作用】
この発明は、前記のように構成されているので、籾米は脱ぷ装置２でその大半が籾殻を摺り剥がれ、玄米と若干の籾米の混入している混合米となつて、選別円筒５内供給樋２８内の供給ラセン２７で、機体前側の選別終端側から後側の選別始端側に移送され、選別円筒５の後側の選別始端側に供給される。
【０００６】
すると、駆動ロ−ラ７，７，…及び円筒フランジ６，６により、選別円筒５が横軸回りに回転しているので、その壷穴４，４，…で混合米が汲み上げられて、長い籾米は壷穴４への嵌入比率が浅いので、比較的低い位置で落下し、一方、玄米は籾殻が剥がれて小さくなっているので、壷穴４への嵌入比率が深くなり、高い位置まで持ち上げられて壷穴４から落下し、玄米受樋２６で受け止められて、下方で落下した籾米と分離される。そして、玄米受樋２６に受けられた玄米は、選別円筒５の後側の選別始端側から前側の選別終端側に向けて、玄米ラセン２５で移送して取り出される。
【０００７】
脱ぷする籾米の種類が変わって、壷穴４，４，…の大きさが異なる選別円筒５に取り替えるときや、選別円筒５の壷穴４，４，…を清掃するときは、次のようにする。即ち、後板１１を選別ケ−ス８から外すと共に、この後板１１と玄米受樋２６・玄米ラセン２５及び供給樋２８・供給ラセン２７を連結支持する支持板３０とを取り外す。すると、選別ケ−ス８は後側が開放されると共に、選別円筒５内に位置している玄米受樋２６・玄米ラセン２５及び供給樋２８・供給ラセン２７は、後部が支持板３０に連結支持された状態で選別ケ−ス８の前板８ａだけで支持された片持ち状態となり、この開放された大きな穴から選別円筒５だけを後方に引き出し、取り外すことができる。また、選別円筒５を取り付ける際には、選別円筒５を後側から前側に移動させることにより、選別円筒５の前後両側の円筒フランジ６，６を前後の駆動ロ−ラ７，７に合致させて取り付ける。
【０００８】
そして、選別円筒５の前側の円筒フランジ６を前側の駆動ロ−ラ７，７から着脱するに際して、駆動ロ−ラ７，７と案内カラ−３１の相互間の移動が円滑化され、位置決めが容易となる。
【０００９】
【００１０】
【実施例】
以下、図面に示すこの発明の実施例について説明する。１は、前後に長い箱状の風選装置で、その前端に吸引フアン１４が設けられ、この吸引フアン１４には、後方に延びる選別風路１５が連なっている。また、選別風路１５の下方には、後述の各穀粒収集樋等が配置されている。この風選装置１の上部前側に、脱ぷ装置２が載置される。その脱ぷ装置２は、公知のものであつて、籾ホッパ１２や脱ぷロ−ル１３，１３等から構成される。
【００１１】
１６は、選別風路１５の下方に配置した摺落米の収集樋で、揚穀装置１７を介して回転選別装置３の前側に設けた供給タンク１８に連通されている。３は、回転選別装置で、風選装置１の後側上部に載置されていて、選別ケ−ス８で被覆されている。選別ケ−ス８の前板８ａの下部と後枠９の下部との間には、一対の駆動ロ−ラ軸２１，２１が架設されていて、この駆動ロ−ラ軸２１，２１の前後両端には、前後の駆動ロ−ラ７，７，…が夫れ夫れ取り付けられている。この駆動ロ−ラ７，７の上方には、選別円筒５が載置されて、選別円筒５の内面には多数の壷穴４，４，…が構成され、選別円筒５の外周部前後両端には、駆動ロ−ラ７，７に支持される円筒フランジ６，６が取り付けされている。
【００１２】
しかして、駆動ロ−ラ軸２１，２１及び駆動ロ−ラ７，７で、円筒フランジ６，６を介して選別円筒５を回転させる構成である。選別円筒５の前側の円筒フランジ６の鍔部６ａは、駆動ロ−ラ７，７の後側面に当接し、また、後側の円筒フランジ６の鍔部６ａは、後側の駆動ロ−ラ７，７の前側面に当接して、選別円筒５の前後の動きを規制している。
【００１３】
選別ケ−ス８を構成する天板２０は、左右の側板１９，１９にネジで止めて着脱可能な構成とし、また、後板１１は、天板２０と後枠９とにネジにより着脱自在に構成している。更に、選別円筒５内には、玄米の玄米受樋２６を架設すると共に、この玄米受樋２６の内部には前側へ移送作用をする玄米ラセン２５を配設し、また、供給タンク１８の下方には供給樋２８の搬送始端側を連設し、この供給樋２８の内部には混合米を後側ヘ移送する供給ラセン２７を配設し、供給樋２８の終端部には、混合米を選別円筒５に供給する供給部を構成している。そして、この玄米受樋２６及び供給樋２８の前端部を、前板８ａに連結支持し、その後端には支持板３０を取り付け、この支持板３０の外周部をネジ２９あるいはピンで固着あるいは係合し、後板１１に着脱自在に支持する構成としている。
【００１４】
３５は玄米流下路、３６は玄米流下板であつて、玄米収集樋４２に連通している。３８は、選別円筒５の終端から排出される籾流下路であつて、籾収集樋３９，籾揚穀機４０を介して脱ぷ装置２の籾ホッパ１２に連通している。また、玄米流下路３５は、玄米流下板３６を介して選別風路１５下方の玄米収集樋４２に連通されていて、玄米揚穀機４３により機外へ取出可能に構成されている。
【００１５】
次に、図３に基づき選別円筒５の着脱容易化構成について説明する。前記左右の駆動ロ−ラ軸２１，２１における前側の駆動ロ−ラ７，７の後側近傍には、案内カラ−３１を設けている。この案内カラ−３１は、前側に位置する後側ほど大径となる前側円錐部３２、及び、該前側円錐部３２の後端に接続していて、且つ、前端部は大径で前側円錐部３２と同一の大径で、後側ほど順次小径となる後側筒部３３から構成されていて、前側の駆動ロ−ラ７，７の後側面から前側円錐部３２の後端部までの前後長さを、円筒フランジ６の前後長さよりも短く構成している。
【００１６】
しかして、図３の実線でに示すように、前側の円筒フランジ６の鍔部６ａが、案内カラ−３１の後側筒部３３の大径の前端部に位置する状態では、円筒フランジ６の小径の駆動ローラ７，７の接触面が駆動ロ−ラ７，７から少し浮き上がった状態となり、この状態から円筒フランジ６を前側円錐部３２に沿って順次前側に移動させると、円筒フランジ６の小径前記の接触面が駆動ロ−ラ７，７に接触支持される状態となり、円筒フランジ６と駆動ロ−ラ７，７との位置決めの円滑化を図っている。
【００１７】
次に、図４により選別円筒５を被覆する選別ケ−ス８の他の実施例について説明する。選別ケ−ス８の後側下部に、穀粒タンク４５を形成し、その底部に開閉弁４６を構成している。このように構成することにより、選別円筒５から漏れた穀粒を穀粒タンク４５に収集できて、穀粒の回収が容易となる。次に、図５に基づき、玄米受樋２６及び供給樋２８の他の実施例について説明する。玄米受樋２６及び供給樋２８を網により構成し、底部には玄米ラセン２５及び供給ラセン２７を夫れ夫れ配置している。しかして、穀粒の移送中に発生した糠，小米等を網目から落下することができ、受樋底部に糠等の残留を防止して、ツヅリ虫の発生を防止できる。なお、この受樋底部を開閉出来る構成としてもよく、また、籾摺選別機の穀粒受樋部分を全部このような網材で構成してもよい。
【００１８】
次に、作用について説明する。脱ぷ装置２の籾ホッパ１２に供給された籾米は、脱ぷロ−ル１３，１３により大半が脱ぷされ、摺落米となつて下方の選別風路１５に落下し、籾殻や塵埃を風選除去された後、混合米として収集樋１６に収集され、揚穀装置１７により供給タンク１８へ供給される。
【００１９】
次いで、供給タンク１８から供給樋２８に供給された混合米は、選別円筒５の前側の選別終端側から後側の選別始端側に移送され、開口部から選別円筒５内に供給される。次いで、図２に示すように、選別円筒５の時計方向への回転に伴い、混合米は多数の壷穴４，４，…に嵌入して上方に持ち上げられ、長い籾米は低い位置で壷穴４，４，…から落下し、籾殻が剥がれて短くなっている玄米だけが高い位置まで持ち上げられて、玄米受樋２６に落下回収される。
【００２０】
玄米受樋２６に回収された玄米は、玄米ラセン２５によつて前側に移送され、玄米流下通路３５，玄米流下板３６を経て、玄米収集樋４２に供給され、更に、玄米揚穀機４３によつて機外へ取り出される。また、選別円筒５の選別終端側から排出される選別後の籾米は、籾流下路３８を経て、籾収集樋３９に回収され、更に籾揚穀機４０によつて脱ぷ装置２の籾ホッパ１２に還元される。
【００２１】
次に、選別円筒５を清掃する場合や、異なる大きさの壷穴４，４，…の選別円筒５と交換したい時の選別円筒５の着脱について説明する。まず、ネジを外し選別ケ−ス８から後板１１を取り外す。次に、選別円筒５の後部を少し持ち上げながら後方へ引き出す。すると、選別円筒５の前側の円筒フランジ６の鍔部分が、案内カラ−３１及び駆動ロ−ラ軸２１，２１に支持されつつ、選別円筒５が集穀樋等に当たって損傷等の生じるようなこともなく、円滑に取り出すことができる。
【００２２】
駆動ロ−ラ軸２１，２１の前側の駆動ロ−ラ７，７の後側には、後側ほど大径となる前側円錐部３２、及び、前側円錐部３２の後端に接続していて後側が小径の後側筒部３３からなる案内カラ−３１を設けているので、選別円筒５の前側の円筒フランジ６の駆動ロ−ラ７，７と案内カラ−３１との間の移動が円滑化されて、駆動ロ−ラ７への選別円筒５の前側の円筒フランジ６の位置決めが容易となり、選別円筒５の着脱が一層円滑となる。
【００２３】
【発明の効果】
この発明によると、選別円筒５は、その中の玄米受樋２６・玄米ラセン２５及び供給樋２８・供給ラセン２７を選別ケース８内に残して、単独でこの選別ケース８から引き抜かれ、選別円筒５の着脱を容易にしたものでありながら、駆動ローラ軸２１，２１の前側の駆動ローラ７，７の後端には後側ほど大径となる前側円錐部３２，該前側円錐部３２の後端に接続していて後側が小径の後側円錐部３３からなる案内カラー３１を設けているので、選別円筒５の前側の円筒フランジ６の駆動ローラ７，７と案内カラー３１との間の移動が円滑化されて位置決めが容易となり、選別円筒５の着脱が一層円滑となる。

Next, the operation will be described. Most of the glutinous rice supplied to the hopper 12 of the detaching apparatus 2 is deflated by the detaching rolls 13 and 13 and falls into the lower sorting air passage 15 as crushed rice. After being removed by wind separation, the mixed rice is collected in the collecting basket 16 and supplied to the supply tank 18 by the cerealing device 17.
[0019]
Next, the mixed rice supplied from the supply tank 18 to the supply trough 28 is transferred from the front side of the sorting cylinder 5 to the rear side of the sorting end, and is fed into the sorting cylinder 5 from the opening. Next, as shown in FIG. 2, as the sorting cylinder 5 rotates in the clockwise direction, the mixed rice is inserted into a number of pits 4, 4,. Only the brown rice that has fallen from 4, 4,... And has been shortened by peeling off the rice husks is lifted to a high position and dropped and collected in the brown rice receiving bowl 26.
[0020]
The brown rice collected in the brown rice receiver 26 is transferred to the front side by the brown rice helix 25, supplied to the brown rice collection basket 42 through the brown rice flow passage 35 and the brown rice flow plate 36, and further to the brown rice cereal machine 43. Therefore, it is taken out of the machine. The sorted rice discharged from the sorting end of the sorting cylinder 5 is collected by the straw collecting basket 39 through the straw downstream 38, and is further collected by the straw milling machine 40. Reduced to 12.
[0021]
Next, a description will be given of attachment / detachment of the sorting cylinder 5 when cleaning the sorting cylinder 5 or when it is desired to replace the sorting cylinder 5 with the pit holes 4, 4,. First, the screw is removed and the rear plate 11 is removed from the sorting case 8. Next, the rear part of the sorting cylinder 5 is pulled up backward while slightly lifting. As a result, the selection cylinder 5 hits the grain collection basket etc. and damage occurs while the flange portion of the cylindrical flange 6 on the front side of the selection cylinder 5 is supported by the guide collar 31 and the drive roller shafts 21, 21. And can be taken out smoothly.
[0022]
On the rear side of the drive rollers 7, 7 on the front side of the drive roller shafts 21, 21, the front cone part 32 having a larger diameter toward the rear side and the rear end of the front cone part 32 are connected. Since the rear side is provided with the guide collar 31 composed of the rear cylindrical portion 33 with a small diameter, the movement between the driving rollers 7 and 7 of the cylindrical flange 6 on the front side of the sorting cylinder 5 and the guide collar 31 is smooth. As a result, the positioning of the cylindrical flange 6 on the front side of the sorting cylinder 5 with respect to the drive roller 7 is facilitated, and the sorting cylinder 5 can be attached and detached more smoothly.
[0023]
【The invention's effect】
According to the present invention, the sorting cylinder 5 is pulled out from the sorting case 8 alone, leaving the brown rice receiving bowl 26, the brown rice spiral 25 and the feeding bowl 28, the feeding spiral 27 in the sorting case 8, and the sorting cylinder 5 is separated. yet those 5 to facilitate attachment and detachment of the front conical portion 32 becomes large as the rear to front of the rear end of the driving roller 7 and 7 of the drive roller shafts 21, after the front side conical section 32 Since the guide collar 31 connected to the end and having the rear conical portion 33 having a small diameter on the rear side is provided, the movement between the driving rollers 7 and 7 of the front cylindrical flange 6 of the sorting cylinder 5 and the guide collar 31 is performed. Is smoothed to facilitate positioning, and the sorting cylinder 5 can be attached and detached more smoothly.
