本発明は、上述した課題を解決するために、次の如き技術手段を講じた。
すなわち、請求項１記載の本発明は、扱室（３）からの排塵物を受け入れて軸芯方向に移送しながら処理する排塵処理胴（１７）を排塵処理室（１８）内に軸架させて設け、この排塵処理室（１８）内で処理された被処理物を下方の揺動選別棚（４０）上に直接導く第１濾過経路（２２）と、この排塵処理室（１８）内で処理された被処理物を揺動選別棚（４０）の側端部よりも外方を迂回して揺動選別棚（４０）上に導く第２濾過経路（２６）とを設けたことを特徴とする脱穀処理装置とする。 The present invention has taken the following technical means in order to solve the above-described problems.
That is, according to the present invention, the dust removal cylinder (17) for receiving dust discharged from the handling chamber (3) and processing it while moving it in the axial direction is disposed in the dust treatment chamber (18). A first filtration path (22) that is provided on a shaft and that directly guides an object to be processed in the dust processing chamber (18) onto the lower swing sorting shelf (40), and the dust processing chamber. A second filtration path (26) that guides the workpiece processed in (18) to the swing sorting shelf (40) by bypassing the outside from the side end of the swing sorting shelf (40). It is set as the threshing processing apparatus characterized by having provided.

扱室３終端より排塵処理室１８内に取り込まれた排塵物は、排塵処理胴１７の回転によって排塵処理室１８内を移送されながら処理され、処理された被処理物は、第１濾過経路２２及び第２濾過経路２６で濾過されて下方の揺動選別棚４０上に導かれる。 The dust collected in the dust processing chamber 18 from the end of the handling chamber 3 is processed while being transported through the dust processing chamber 18 by the rotation of the dust processing cylinder 17, and the processed object to be processed is It is filtered by the first filtration path 22 and the second filtration path 26 and guided to the lower swing sorting shelf 40.

請求項２記載の本発明は、前記第２濾過経路（２６）を、排塵処理室（１８）下側の第２濾過孔（２７）から所定の落差（Ｈ）をおいて傾斜配置する流下案内板（２９）によって形成したことを特徴とする請求項１記載の脱穀処理装置とする。 According to the present invention as set forth in claim 2, the second filtration path (26) is arranged so as to be inclined with a predetermined drop (H) from the second filtration hole (27) below the dust disposal chamber (18). The threshing processing device according to claim 1, wherein the threshing processing device is formed by a guide plate (29).

第２濾過孔２７から濾過した被処理物は、下方の流下案内板２９上に落下し、この流下案内板２９上を揺動選別棚４０側に向けて流下して、揺動選別棚４０上に供給される。
第２濾過孔２７と流下案内板２９との間には、所定の落差Ｈの空間を設けているので、流下案内板上での被処理物の停滞や第２濾過孔２７部での詰まりが少なくなる。 The object to be processed filtered from the second filtration hole 27 falls on the lower flow guide plate 29, flows down on the flow guide plate 29 toward the swing sorting shelf 40, and on the swing sorting shelf 40. To be supplied.
Since a space of a predetermined drop H is provided between the second filtration hole 27 and the flow down guide plate 29, the stagnation of the object to be processed on the flow down guide plate and clogging at the second filtration hole 27 portion. Less.

請求項３記載の本発明は、前記第１濾過経路（２２）における第１濾過孔（２３）の目合を、第２濾過経路（２６）における第２濾過孔（２７）の目合よりも大きく設定したことを特徴とする請求項１又は請求項２記載の脱穀処理装置とする。 According to the third aspect of the present invention, the degree of the first filtration hole (23) in the first filtration path (22) is made larger than the degree of the second filtration hole (27) in the second filtration path (26). The threshing processing apparatus according to claim 1, wherein the threshing processing apparatus is set large.

排塵処理胴１７の側面部の第１濾過孔２３に対し、第２濾過孔２７は排塵処理胴１７の下側に設けられているために被処理物が漏下し易いが、この第２濾過孔２７の目合を小さくすることによって、不要なワラ塵や枝梗付着粒、カギ又などが多量に漏下することが抑制される。これにより、下方の流下案内板２９上での詰まりを防止すると共に、湿材等で第２濾過孔２７の目合が詰まり易い条件下でも目合を大きく設定してある第１濾過孔２３からの濾過が容易であり、３番ロスの急増が抑制される。 The second filtration hole 27 is provided below the dust removal treatment cylinder 17 with respect to the first filtration hole 23 on the side surface portion of the dust removal treatment cylinder 17, so that the object to be processed is likely to leak. 2 By reducing the mesh size of the filter hole 27, it is possible to suppress unnecessary leakage of dust, branch leaf adhesion grains, keys or the like. This prevents the clogging on the lower flow guide plate 29 and prevents the clogging of the second filtration hole 27 from being easily clogged with a wet material or the like from the first filtration hole 23 which is set to be large. And the rapid increase of the third loss is suppressed.

請求項１記載の本発明によると、排塵処理室１８からの漏下物は、第１濾過経路２２と第２濾過経路２６とを経て揺動選別棚４０上に導かれるために、排塵処理室１８における実質的な濾過面積が拡大されて濾過能力が高められ、脱穀処理作業の能率を向上させることができる。 According to the first aspect of the present invention, since the leakage from the dust processing chamber 18 is guided to the swing sorting shelf 40 through the first filtration path 22 and the second filtration path 26, the dust discharge The substantial filtration area in the treatment chamber 18 is expanded, the filtration ability is increased, and the efficiency of the threshing treatment work can be improved.

また、請求項２記載の本発明によれば、上記請求項１記載の発明による効果を奏するものでありながら、第２濾過孔２７からの漏下物は、下方に臨む流下案内板２９によって揺動選別棚４０上に導くことができ、しかも、この第２濾過孔２７と流下案内板２９との間には、所定の落差Ｈの空間を設けているので、流下案内板２９上での被処理物の停滞や第２濾過孔２７部での詰まりを防止でき、揺動選別棚４０上へ円滑に案内落下させることによって、脱穀処理作業の能率を向上させることができる。 According to the second aspect of the present invention, the leakage from the second filtration hole 27 is shaken by the flow-down guide plate 29 facing downward, while achieving the effect of the first aspect of the invention. Moreover, since a space with a predetermined drop H is provided between the second filtering hole 27 and the flow guide plate 29, it can be guided onto the moving sorting shelf 40. Stagnation of the processed product and clogging at the second filtration hole 27 portion can be prevented, and the efficiency of the threshing processing work can be improved by smoothly guiding and dropping onto the swing sorting shelf 40.

請求項３記載の本発明によれば、請求項１又は請求項２記載の発明の効果に加えて、第１濾過経路２２における第１濾過孔２３の目合が、第２濾過経路２６における第２濾過孔２７よりも大きく設定されているので、第１濾過孔２３より目合の小さい第２濾過孔２７では、不要なワラ塵や枝梗付着粒、カギ又などが多量に濾過するのを抑制でき、下方の流下案内板２９上での詰まりを防止でき、湿材等で第２濾過孔２７の目合が詰まり易い条件下でも、目合を大きく設定してある第１濾過孔２３からの漏下が容易となり、３番ロスの急増を抑制することができることによって、脱穀処理作業の効率を向上させることができる。 According to the third aspect of the present invention, in addition to the effect of the first or second aspect of the invention, the degree of the first filtration hole 23 in the first filtration path 22 is the same as that of the second filtration path 26. Since the second filter hole 27 is smaller than the first filter hole 23, unnecessary wall dust, branch leaf adhering grains, keys, etc. are filtered in a large amount. It is possible to prevent clogging on the lower flow guide plate 29 and to prevent the clogging of the second filtration hole 27 with a wet material, etc. And the efficiency of the threshing treatment work can be improved by suppressing the rapid increase of the third loss.

以下、本発明の実施例を図面に基づいて具体的に説明する。
図１及び図２は、コンバインに搭載する脱穀装置を示すもので、まず、この構成につき説明する。 Embodiments of the present invention will be specifically described below with reference to the drawings.
FIG.1 and FIG.2 shows the threshing apparatus mounted in a combine, First, it demonstrates per this structure.

扱歯１付扱胴２を内装軸架した扱室３の下半周部に沿って受網４を張設している。５は扱室３の上方部を覆う扱胴カバ−であって、扱胴軸方向に平行な軸芯回りに揺動開閉可能に構成している。 A receiving net 4 is stretched along the lower half of the handling chamber 3 in which the handling cylinder 2 with the tooth handling 1 is mounted on the interior. Reference numeral 5 denotes a handling cylinder cover that covers the upper part of the handling chamber 3, and is configured to be swingable around an axis parallel to the handling axis direction.

扱室３の扱口側には穀稈を挟持搬送するフィ−ドチェン６とこの上側に対設する挟持レ−ル７を配設している。この挟持レ−ル７は扱胴カバ−５側に装着して該カバ−と共に揺動開閉する構成である。８は脱穀後の排ワラを搬出処理する排ワラ搬送装置、９は搬出後の排藁を受け入れて切断処理する排藁カッターを示す。扱室３の終端側には多量の藁屑や未処理物を含む排塵処理物を下方に落下させる排塵口１０が設けらている。 A feed chain 6 for sandwiching and conveying the cereal and a sandwiching rail 7 provided on the upper side are disposed on the handling port side of the handling chamber 3. The clamping rail 7 is mounted on the side of the barrel cover 5 and swings and opens together with the cover. 8 is a waste straw conveying device for carrying out the waste straw after carrying out the threshing, and 9 is a waste cutter for receiving and cutting the waste after the carrying out. A dust exhaust port 10 is provided on the terminal side of the handling chamber 3 to drop a dust-treated product containing a large amount of sawdust and untreated material downward.

前記扱室３のフィードチェン６側とは反対側一側には２番処理胴１４を内装軸架した２番処理室１５を並設している。また、前記２番処理胴１４の後方にはこれと同一軸芯上において外周に処理歯１６を備えた排塵処理胴１７を内装軸架した排塵処理胴室１８を構成して設けている。前記扱室終端の排塵口１０に対応する部位から排塵処理室１８始端への送塵路１１には、排塵処理胴１７の始端部に固着されたスパイラ−形状の取込羽根１９が介入するように設けて、排塵処理室１８内への排塵物の取込みが容易に行なえるようにしている。排塵処理胴１７の終端には排出羽根２０が設けられ、処理室終端にまで送られてきた排塵物を前記排出羽根２０によって処理室終端のわら屑排出口２１から後記する揺動選別装置（揺動選別棚）４０の選別棚終端及び機外に排出する構成としている。 On the side opposite to the feed chain 6 side of the handling chamber 3, a second processing chamber 15 in which a second processing cylinder 14 is pivoted is provided in parallel. Further, a dust removal treatment cylinder chamber 18 is provided on the rear side of the second treatment cylinder 14 and includes a dust removal treatment cylinder 17 having a treatment tooth 16 on the outer periphery on the same axis. . Spiral-shaped intake vanes 19 fixed to the start end of the dust removal treatment cylinder 17 are provided in the dust feed passage 11 from the portion corresponding to the dust discharge port 10 at the end of the handling chamber to the start end of the dust removal treatment chamber 18. It is provided so as to intervene so that the dust can be easily taken into the dust processing chamber 18. A discharge blade 20 is provided at the end of the dust removal processing cylinder 17, and the swing sorting device described later from the straw waste discharge port 21 at the end of the processing chamber by the discharge blade 20 discharges dust that has been sent to the end of the processing chamber. (Swinging sorting shelf) 40 is configured to discharge to the end of the sorting shelf and to the outside of the machine.

前記排塵処理室１８には処理された処理物を下方の揺動選別棚４０上に直接導く第１濾過経路２２と、揺動選別棚幅（選別室幅）より外方から揺動選別棚上に導く第２濾過経路２６を設けている。第１濾過経路２２は、排塵処理胴１７の側面部に対応する部位において第１濾過孔２３を形設する格子状の受網２４とガイドフィン２５とによって構成してあり、処理された処理物を下方の揺動選別棚４０上に直接導くようにしている。第２濾過経路２６は、排塵処理胴の下方に対応する部位において第２濾過孔２７を有するクリンプ網状の受網２８と、上下方向の傾斜下端側が揺動選別棚上に臨み、傾斜上端側が第２濾過孔２７から所定の落差Ｈをもって下方に臨む流下案内板２９とによって構成してあり、受網２８の第２濾過孔２７から濾過する処理物を流下案内板２９によって揺動選別棚上へ案内落下させるようにしている。 The dust treatment chamber 18 has a first filtration path 22 that directly guides the processed product onto the lower swing sorting shelf 40, and a swing sorting shelf from the outside of the swing sorting shelf width (sorting chamber width). A second filtration path 26 leading upward is provided. The first filtration path 22 is configured by a lattice-shaped receiving net 24 and guide fins 25 that form the first filtration holes 23 in a portion corresponding to the side surface portion of the dust removal treatment cylinder 17. The object is directly guided onto the lower swing sorting shelf 40. The second filtration path 26 has a crimped net-like receiving net 28 having a second filtration hole 27 at a portion corresponding to the lower part of the dust removal treatment cylinder, the vertically inclined lower end side faces the swing sorting shelf, and the inclined upper end side is A flow-down guide plate 29 facing downward from the second filtration hole 27 with a predetermined drop H, and the processed material to be filtered from the second filtration hole 27 of the receiving net 28 is swung on the swing sorting shelf by the flow-down guide plate 29. I'm trying to drop the guide.

そして、第２濾過孔２７は、穀粒や細かい塵埃の漏れる通常の大きさの目合Ｌ１とし、第１濾過孔２３は、第２濾過孔２７のそれよりも目合Ｌ２をより大きく設定して濾過効率を高めるようにしている。 The second filtering hole 27 has a normal size L1 through which grains and fine dust leak, and the first filtering hole 23 has a larger size L2 than that of the second filtering hole 27. To improve filtration efficiency.

なお、実施例では、処理室の濾過部包囲角度（第１濾過孔部と第２濾過孔部を含む）は、処理胴包囲角度の約半分（１８０度近く）を占めるように構成してあり、充分な濾過面積の確保によって処理物の濾過作用が効率良く行える。 In the embodiment, the filtration chamber surrounding angle (including the first filtration hole portion and the second filtration hole portion) of the processing chamber is configured to occupy about half (nearly 180 degrees) of the processing cylinder surrounding angle. By securing a sufficient filtration area, it is possible to efficiently perform the filtering action of the processed material.

また、排塵処理室の第１濾過孔２３及び第２濾過孔２７は、扱室終端の排塵口１０から排塵処理室１８始端への連通送塵路１１を除く後方位置に設ける構成としている。排塵処理室始端の送塵路１１部では、藁塵と穀粒の分離が充分とは云えず、また、濾過機能を促進するための仕切抵抗体を送塵路部近くに設けると、処理物の後方への送塵を止めるようになるので、扱室終端部での持ち回り処理物が増加し、脱穀負荷の増大を招くが、このような問題点を解消することができる。 Further, the first filtration hole 23 and the second filtration hole 27 of the dust removal treatment chamber are provided at a rear position excluding the communication dust passage 11 from the dust discharge port 10 at the end of the handling chamber to the start end of the dust treatment chamber 18. Yes. In the dust supply passage 11 at the beginning of the dust removal treatment chamber, the separation of dust and grains cannot be said to be sufficient, and if a partition resistor for promoting the filtration function is provided near the dust supply passage, Since the dust feeding to the rear of the object is stopped, the number of items to be carried around at the terminal end of the handling chamber increases and the threshing load increases, but such a problem can be solved.

第２濾過孔２７を有する受網２８上及び処理胴１７の回転方向下手側にわたる処理室ケーシング３０内面に処理物の移送抵抗を付与する仕切抵抗体３１を設けることで、第２濾過孔２７からの穀粒の濾過促進を図るようにしている。各仕切抵抗体３１，３１…は、前後の設置幅Ｄ１を第２濾過孔２７の濾過幅Ｄ２と略同じくすることで、各仕切抵抗体で処理物の送塵に抵抗をかけながら処理物を良くこなす部位での濾過を促進し、効率よく処理物中の穀粒を回収することができる。また、各仕切抵抗体のうち、前方側の仕切抵抗体３１ｆでは抵抗度合を小さく（送り方向への若干の傾斜角度を設ける）し、後方側の仕切抵抗体３１ｒでは抵抗度合を大きく（前方側の傾斜角より急傾斜角又は処理胴軸と直交する）している。排塵処理室の始端側（送塵路）近くで過度の抵抗を加えると送塵路部で処理物が充満し、扱室内での脱穀過負荷に伴う作業能率低下や藁塵と穀粒が分離不充分のまま揺動選別棚上に多量に排出されるなどの不具合があるので、前方側では抵抗度合を小さくし、後方側では抵抗度合を大きくすることによって解消することができる。 By providing a partition resistor 31 for providing a transfer resistance of the processed material on the inner surface of the processing chamber casing 30 over the receiving net 28 having the second filtering hole 27 and the lower side in the rotational direction of the processing cylinder 17, the second filtering hole 27 Is trying to promote the filtration of grain. Each partition resistor 31, 31... Has a front and rear installation width D 1 substantially the same as the filtration width D 2 of the second filtration hole 27. Filtration at a well-treated site is promoted, and the grains in the processed product can be efficiently recovered. In addition, among the partition resistors, the resistance value of the partition resistor 31f on the front side is reduced (provides a slight inclination angle in the feed direction), and the resistance level is increased on the partition resistor 31r on the rear side (front side). The inclination angle is more steep than the inclination angle or perpendicular to the processing cylinder axis). If excessive resistance is applied near the start side (dust feeding path) of the dust processing chamber, the treated material will be filled in the dust feeding path, resulting in reduced work efficiency due to threshing overload in the handling chamber and dust and grains. Since there is a problem that a large amount is discharged onto the swing sorting shelf with insufficient separation, it can be solved by reducing the resistance degree on the front side and increasing the resistance degree on the rear side.

排塵処理胴１７の外周に処理物を軸芯方向後方に送りながら処理する螺旋処理体３２を券回し、この螺旋処理体３２の外周縁部には所定間隔置きに切欠凹部３３を切欠き形成して設けると共に、この切欠凹部３３に前記処理歯１６を取付ボルト３４によって一体的に締付固定する構成としている。 A spiral processing body 32 is processed around the outer periphery of the dust removal processing cylinder 17 while feeding the processed object backward in the axial direction, and cutout recesses 33 are formed in the outer peripheral edge of the spiral processing body 32 at predetermined intervals. In addition, the processing teeth 16 are integrally fastened and fixed to the notch recesses 33 by mounting bolts 34.

排塵処理室１８の後方部を開放し、処理室後側板３５によって軸支される排塵処理胴１７からの排塵処理物を後方排出口２１Ｒを介して直接機外後方へ排出できるように構成している。後方への機外排出を可能とすることで、前方部から多量に送塵された処理物を速やかに機外排出ができるようになり、高藁塵流量に対応でき能率の向上が図れる。後方排出口２１Ｒから後方へ排出される排塵物は、後方排出ガイド板３５によって機体後方側へ排出案内落下される。 The rear part of the dust processing chamber 18 is opened so that the dust processing product from the dust processing cylinder 17 that is pivotally supported by the processing chamber rear plate 35 can be discharged directly outside the machine through the rear discharge port 21R. It is composed. By enabling the discharge outside the machine to the rear, it becomes possible to quickly discharge the processed material sent from the front part to the outside of the machine, which can cope with a high dust flow rate and improve the efficiency. Dust discharged from the rear discharge port 21R to the rear is discharged and dropped by the rear discharge guide plate 35 to the rear side of the machine body.

扱室終端より排塵処理室１８内に取り込まれた排塵処理物は、排塵処理胴１７の螺旋処理体３２によって後方に移送されながら螺旋処理体外周の処理歯１６によってこなされ、第１受網２４の濾過穴２３及び第２受網２８の濾過孔２７より濾過される。第１濾過孔２３からの濾過物はガイドフィン２５を介して直接下方の揺動選別棚上に落下され、また、第２濾過孔２７からの濾過物は流下案内板２９上に受けられて扱室下方の選別室側へ案内落下され揺動選別棚４０上に導かれる。排塵処理室終端では、排出すべきわら屑などの排塵物が処理胴終端の排出羽根２０によりわら屑排出口２１から揺動選別棚終端上へ、また、後方排出口２１Ｒから機外後方へ排出されることになる。 The dust exhausted material taken into the dust processing chamber 18 from the end of the handling chamber is processed by the processing teeth 16 on the outer periphery of the spiral processing body while being transferred backward by the spiral processing body 32 of the dust processing cylinder 17. Filtering is performed from the filtering hole 23 of the receiving net 24 and the filtering hole 27 of the second receiving net 28. The filtrate from the first filter hole 23 is dropped directly onto the swing sorting shelf below through the guide fins 25, and the filtrate from the second filter hole 27 is received on the flow guide plate 29 and handled. It is guided and dropped to the sorting chamber side below the chamber and guided onto the swing sorting shelf 40. At the end of the dust disposal chamber, waste such as straw waste to be discharged is discharged from the straw waste outlet 21 onto the swing sorting shelf end by the discharge blade 20 at the end of the processing cylinder, and from the rear outlet 21R to the rear outside the machine. Will be discharged.

扱室３の下側には揺動可能に架設した揺動選別装置（揺動選別棚）４０を設け、更に、その下方には選別方向の上手側から順に、唐箕４１と、１番移送螺旋４２と、２番移送螺旋４３と、その上方に片側吸引方式の吸引排塵ファン４４を設けて選別室を構成している。なお、１番揚穀装置４５は１番移送螺旋４２で回収された穀物を揚送してグレンタンク内に収容する。また、２番揚穀装置４６は２番移送螺旋４３で回収された２番物を２番処理胴１４の２番処理室１５内へ還元するようになっている。 A swing sorting device (swing sorting shelf) 40 is provided below the handling chamber 3 so as to be swingable, and further below, the Kara 41 and the first transfer spiral in order from the upper side of the sorting direction. 42, a second transfer spiral 43, and a suction dust exhaust fan 44 of a one-side suction system are provided above it to constitute a sorting chamber. The first cerealing device 45 lifts the grains collected by the first transfer spiral 42 and stores them in the Glen tank. The second cerealing device 46 is configured to return the second item collected by the second transfer spiral 43 into the second processing chamber 15 of the second processing cylinder 14.

そして、揺動選別棚４０は、扱室からの脱穀処理後の処理物及び排塵処理室からの処理物を受け入れて揺動移送しながらふるい選別する構成であり、選別方向上手側から移送棚４７、チャフシーブ４８、ストローラック４９の順に配置し、且つ、前記チャフシーブ４８の下方にグレンシーブ５０を配置して設け、前記唐箕４１及び吸引排塵ファン４４による選別風と揺動との共同作用によって扱室３及び排塵処理室１８から漏下してきた処理物を受け入れて揺動移送しながらふるい選別処理するように構成している。なお、前記チャフシーブ４８は、複数枚の帯板状のシーブ板４３ａを等間隔に配置して上部を枢着４３ｂし、下部が円弧状の長孔４３ｃに沿って揺動開閉するようにして相互の選別間隔の開度調節ができる構成としている。 The swing sorting shelf 40 is configured to receive the processed product from the threshing process from the handling chamber and the processed product from the dust processing chamber, and screen and sort the screen while swinging and transporting from the upper side of the sorting direction. 47, chaff sheave 48 and stroll rack 49 are arranged in this order, and a glensieve 50 is arranged below the chaff sheave 48, and is handled by the combined action of the selection wind and the swinging by the tang 41 and the suction dust fan 44. It is configured to receive the processed material leaked from the chamber 3 and the dust processing chamber 18 and perform a sieve sorting process while swinging and transferring the processed material. The chaff sheave 48 has a plurality of strip plate-like sheave plates 43a arranged at equal intervals so that the upper portion is pivotally attached 43b, and the lower portion is swingably opened and closed along an arc-shaped elongated hole 43c. The opening of the sorting interval can be adjusted.

扱室３内に供給される穀稈は、株元がフィ−ドチェン６に挾持されて搬送されながら穂先部分が扱室３内に供給されて、回転している扱胴２により脱穀作用を受ける。このようにして処理された脱穀処理物は、回転している扱胴２によって持ち回りされて、更に、脱粒処理作用を受け、受網４から漏下して選別室の揺動選別装置４０に達し揺動選別作用を受ける。 The cereals supplied into the handling chamber 3 are subjected to the threshing action by the rotating handling cylinder 2 while the tip is supplied into the handling chamber 3 while the stock is held and fed by the feed chain 6. . The threshing processed material processed in this way is carried around by the rotating barrel 2 and further subjected to a threshing treatment action, leaks from the receiving net 4 and reaches the swinging sorting device 40 in the sorting chamber. Subject to rocking selection.

この場合、扱室の始端側で脱穀処理された処理物は、移送棚４７上に落下して後方へ揺動移送されてチャフシ−ブ４８に達する。また、扱室終端に至った排塵処理物は、排塵口１０から下方のチャフシーブ４８上に落下するものと、送塵路１１を経て排塵処理室１８内へ送られて排塵処理胴１７により処理されるものとに分かれる。そして、チャフシーブ４８上での排塵処理物は、チャフシ−ブ４８を構成している複数枚のシ−ブ板４８ａ…相互間にある選別間隔を漏下しながら風選作用を受ける。 In this case, the processed product that has been threshed on the start end side of the handling chamber falls on the transfer shelf 47 and is oscillated and moved rearward to reach the chaff sheave 48. In addition, the dust disposal product that has reached the end of the handling chamber falls on the chaff sheave 48 below from the dust outlet 10 and is sent to the dust disposal chamber 18 through the dust delivery path 11 to be collected in the dust disposal cylinder. 17 to be processed. Then, the dust exhausted product on the chaff sheave 48 is subjected to a wind-selecting action while leaking a sorting interval between the plurality of sheave plates 48 a constituting the chaff sheave 48.

チャフシ−ブ４８から漏下するものはグレンシーブ５０上に落下しここでふるい選別されながら風選作用を受ける。このとき、唐箕４１は、起風した選別風を選別室内に吹き込みながら選別し、吸引排塵フアン４４による吸引作用によって選別される。 What leaks from the chaff sheave 48 falls on the Glen sieve 50 and is subjected to wind selection while being screened. At this time, the Kara 41 is sorted by blowing up the raised sorting wind into the sorting chamber, and is sorted by the suction action by the suction dust fan 44.

このようにして、処理物は、揺動選別作用と選別風による風選作用との共同作用を受けながら選別されて、１番物（精粒）、２番物、排塵物とに選別分離され、１番物はグレンシ−ブ５０にてふるい選別された後、１番移送螺旋４２の受樋内に落下して収集されて機外に取り出されグレンタンク内に収容される。２番物は２番移送螺旋４３から２番揚穀装置４６によって揚穀されて２番処理室１５内に還元され再処理される。そして、排塵物は吸引排塵ファン４４によって吸塵され機外に排出されると共に、ストロ−ラック４９に達したわら屑は棚先から機外に排出される。 In this way, the processed material is sorted while receiving the cooperative action of the oscillating sorting action and the wind sorting action by the sorting wind, and sorted into the first (fine grain), the second, and the dust. Then, the first product is screened and sorted by the glenive 50, and then dropped and collected in the receptacle of the first transfer spiral 42, taken out of the machine, and stored in the glen tank. The second product is cerealed from the second transfer spiral 43 by the second cerealing device 46 and is reduced into the second processing chamber 15 and reprocessed. The dust is sucked by the suction dust fan 44 and discharged outside the machine, and the straw scraps reaching the straw rack 49 are discharged from the shelf end to the outside of the machine.

一方、扱室終端より排塵処理室１８内に取り込まれた排塵処理物は、後方に移送されながら処理胴１７外周の処理歯１６によってこなされ、受網２４の濾過穴２３及び受網２８の濾過孔２７より漏下しチャフシーブ４８上に還元される。排塵処理室１８の終端に至っては、排塵物が処理胴１７終端の排出羽根２０によりストローラック４９上及び機外に排出処理される。 On the other hand, the dust disposal product taken into the dust disposal chamber 18 from the end of the handling chamber is processed by the processing teeth 16 on the outer periphery of the processing cylinder 17 while being transferred rearward, and the filtering holes 23 and the receiving mesh 28 of the receiving mesh 24. It leaks from the filter hole 27 and is reduced onto the chaff sheave 48. When reaching the end of the dust processing chamber 18, the dust is discharged onto the strola rack 49 and out of the machine by the discharge blade 20 at the end of the processing cylinder 17.
