Description

本発明は、コンバインの構成に関する。   The present invention relates to a combine configuration.

従来、脱穀性能及び選別性能を向上させるために、扱胴後部側方で平行に送塵口処理胴を配置し、扱胴で処理できなかった枝梗付着粒等を処理胴に送り処理し、脱穀部で処理する穀粒の内、通常10〜15%の穀粒を単粒化し、処理網を通して下方の選別部の揺動選別装置上へ排出するようにしていた。さらに、脱穀部から流下する穀粒や藁屑等から穀粒を選別装置により選別した後の二番物を、二番コンベア、二番還元コンベアを介して枝梗処理装置へ送り、該枝梗処理装置により枝梗等を取り除いた後に、再び揺動選別装置の選別開始部へ戻し処理するようにしていた。
特開平10−295158号公報
Conventionally, in order to improve the threshing performance and sorting performance, a dust outlet processing cylinder is arranged in parallel on the rear side of the handling cylinder, and the processing of the spike attached particles that could not be processed by the handling cylinder is sent to the processing cylinder, Of the grains to be treated in the threshing unit, usually 10% to 15% of the grains are singulated and discharged through a treatment net onto the oscillating sorting device of the sorting unit below. Further, the second product after the grain is sorted by the sorting device from the grain and straw waste flowing down from the threshing unit is sent to the branch and stalk processing device via the second and second reduction conveyors, and After removing the branch stem etc. by the processing device, the processing is returned to the sorting start portion of the rocking sorting device again.
JP-A-10-295158

しかし、コンバイン本機の高速化、高能率化などによって脱穀処理量が増えてくると、送塵口処理胴の処理物が荒れて処理胴網の濾過が悪くなり、機外への排出量が増えたり、揺動選別装置上に濾過されても、チャフシーブ等で濾過されずに三番口からの機外への排出が増えて、通常の単粒化率の達成も難しくなっていた。特に、送塵口処理胴の直下に多くの穀粒が片寄り集中するため、揺動選別の不良を招くことがあった。
そこで、本発明は三番口などからの穀粒ロスを低減することができ、また揺動選別装置の選別幅を有効に活用して穀粒を増加させることができるコンバインを提供することを目的とする。
However, when the threshing amount increases due to the high speed and high efficiency of the combine machine, the processed material of the dust outlet processing drum becomes rough, the filtration of the processing drum net deteriorates, and the amount of discharge to the outside increases. Even if it is increased or filtered on an oscillating sorter, it is not filtered by a chaff sieve or the like, and the amount of water discharged from the third opening to the outside of the machine increases, making it difficult to achieve a normal single-grain rate. In particular, a large number of grains are concentrated in a non-uniform manner immediately below the dust-carrying port processing cylinder, which may lead to poor swing sorting.
Therefore, an object of the present invention is to provide a combine that can reduce the grain loss from the third opening and the like, and can increase the grain by effectively utilizing the sorting width of the swing sorting device. And

以上の構成において、二番還元コンベア40からの二番物の流れを説明すると、二番物は、供給口41より枝梗処理装置10内へ投入された後、枝梗処理胴11の回転により、該枝梗処理胴11の外周に備える処理歯11a・11a・・・と、枝梗処理装置10の外枠を構成する筒体45の内側面に突設したツースバー51・51・・・とにより、枝梗を除去されつつ排出口42まで搬送され、該排出口42から下方に向けて排出された後、該排出口42の近傍に配置された籾ガイド板43に当たって、揺動選別装置27の選別開始部、即ち、前流穀板30の前方表面上へ落下するように案内される。
本実施例では、該籾ガイド板43の配置は、排出口42の前方とし、該排出口42の開口が、機体正面視中央側にかけて広くなるように構成されている。
In the above configuration, the flow of the second product from the second reduction conveyor 40 will be described. After the second product is introduced into the branch stalk processing apparatus 10 through the supply port 41, the second product is rotated by the rotation of the branch stalk processing cylinder 11. , Processing teeth 11a provided on the outer periphery of the branch stalk processing cylinder 11, and tooth bars 51 projecting from the inner surface of a cylindrical body 45 constituting an outer frame of the branch stalk processing apparatus 10.

次に、本発明について説明する。
図3、図8乃至図10に示す如く、前記処理室29において、送塵口処理胴22の下方に搬送体50が、送塵口処理胴22と平行に平面視で重複するように前後方向に横設されており、該搬送体50によって、送塵口処理胴22から処理胴網24を介して落下する処理物を受け、該処理物を前方、即ち送塵口処理胴22による脱粒物の送り方向と反対方向に搬送して、揺動選別装置27上に排出するように構成されている。
Next, the present invention will be described.
As shown in FIGS. 3, 8 to 10, in the processing chamber 29, the transport body 50 is disposed below the dust port processing cylinder 22 in the front-rear direction so as to overlap with the dust port processing cylinder 22 in plan view. The processing body receives the processed material dropped from the dust-sending port processing cylinder 22 through the processing drum network 24 by the carrier 50, and transfers the processed substance to the front, that is, the deagglomerated material by the dust-sending port processing cylinder 22. Is transported in the direction opposite to the feeding direction of the paper and discharged onto the swing sorting device 27.

該搬送体50は処理室29の下部に前後方向に正面視で漏斗状の受桶52を横設して上方を開放し、該受樋52内に螺旋状体としてスクリュー53を備えてコンベアを構成しており、前記送塵口処理胴22と同様に、側面視において該搬送体50はその搬送始端部を処理胴網24の後端下方に配置し、その搬送終端部を前記扱胴21の終端部側板59より機体進行方向前側に配置して、扱胴21の後部と前後方向で一部重複して配置されている。また、搬送体50及び送塵口処理胴22より前方には前記枝梗処理装置10が配設され、側面視で扱胴21と重複するように配置されている。   The transfer body 50 is provided with a funnel-shaped trough 52 in a lower part of the processing chamber 29 in the front-rear direction as viewed from the front, opened upward, and provided with a screw 53 as a spiral body in the trough 52 to convey the conveyor. As in the case of the dust port processing cylinder 22, the transport body 50 has a transport start end located below the rear end of the processing drum net 24 in a side view, and a transport end located at the transport cylinder 21 in the side view. Is arranged on the front side in the fuselage advancing direction from the end portion side plate 59, and is arranged so as to partially overlap the rear portion of the handling cylinder 21 in the front-rear direction. The branch stalk processing device 10 is disposed in front of the transport body 50 and the dust port processing cylinder 22, and is disposed so as to overlap the handling cylinder 21 in a side view.

また、前記搬送体50と扱胴21とが側面視で重複しない部分において、搬送体50から処理物が落下しないように受桶52の扱胴21側に側壁54が固設される一方、搬送体50と扱胴21とが重複する部分、即ち搬送終端部においては、受桶52の扱胴21側が開放状態とされて排出部52aが形成されている。そして、該排出部52aに位置するスクリュー53の駆動軸55に、板状の羽根56が固着され、該羽根56の回転により処理物を揺動選別装置27の左右中心側へ排出するようにしている。   In a portion where the transport body 50 and the handling cylinder 21 do not overlap in a side view, a side wall 54 is fixedly provided on the handling cylinder 21 side of the receiving tub 52 so that the processed material does not drop from the transport body 50. At a portion where the body 50 and the handling cylinder 21 overlap, that is, at the transport end portion, the handling cylinder 21 side of the receiving tub 52 is opened to form a discharge portion 52a. A plate-like blade 56 is fixed to the drive shaft 55 of the screw 53 located at the discharge portion 52a, and the processed material is discharged to the left and right center sides of the swing sorting device 27 by the rotation of the blade 56. I have.

そして、前記搬送体80の後方にガイド板61を配設している。該ガイド板61は、図8乃至図10に示すように、処理胴22の下方で揺動選別装置27の上方に配置している。ガイド板61の前端位置は処理胴網24の後端より前方に、ガイド板61の後端位置は揺動選別装置27の後端より後方に配置しており、前部を高く後部を低く斜めに形成している。該ガイド板61は、処理胴22の左右方向の幅と略同等として前記吸引ファン25と処理胴カバー76との間に配置しており、ボルト等の固定手段により固定されている。
該ガイド板61は、前記送塵口処理胴22内部の藁屑等を機体外部に案内するもので、前記処理胴22内部の藁屑を前記羽体91・91の回転によって跳ね飛ばし、処理胴22の下方に排出し、前記ガイド板61によって機体外部に案内している。このように、ガイド板61を設けることで、藁屑が前記搬送体50や揺動選別装置27に混ざらずに機体外部に排出することができる。
A guide plate 61 is provided behind the carrier 80. The guide plate 61 is disposed below the processing cylinder 22 and above the swing sorting device 27, as shown in FIGS. The front end position of the guide plate 61 is disposed forward of the rear end of the processing drum 24, and the rear end position of the guide plate 61 is disposed rearward of the rear end of the swing sorting device 27. Is formed. The guide plate 61 is disposed between the suction fan 25 and the processing drum cover 76 with substantially the same width as the width of the processing drum 22 in the left-right direction, and is fixed by fixing means such as bolts.
The guide plate 61 is for guiding the straw chips and the like inside the dust outlet processing drum 22 to the outside of the machine body. The air is discharged to the lower side of the body 22 and is guided to the outside of the machine body by the guide plate 61. By providing the guide plate 61 in this manner, the straw waste can be discharged to the outside of the machine without being mixed with the carrier 50 and the swing sorting device 27.

また、図9に示す如く、搬送体50前方において、スクリュー53の駆動軸55上にギア47aが固定され、該47aは入力軸58の一端に固定されたギア47bと噛合している。そして、該入力軸58の他端にプーリ48aが固着され、該プーリ48aと、送塵口処理胴22の駆動軸34に固着されたプーリ48bとがベルト57で巻回されている。
こうして、前記送塵口処理胴22の駆動軸34にプーリ48a・48b、ベルト57及びギア47a・47bを介して搬送体50の駆動軸55を連動連結させ、送塵口処理胴22の駆動軸34から搬送体50の駆動軸55に動力を伝達するようにして、送塵口処理胴22の回転に応じて搬送体50を回転駆動できるようにしている。
但し、搬送体50の駆動構成は限定するものではなく、チェーン式等であってもよく、また、送塵口処理胴22からだけでなく、下方の選別装置等から動力を伝達する構成とすることもできる。
As shown in FIG. 9, a gear 47a is fixed on the drive shaft 55 of the screw 53 in front of the transport body 50, and the 47a meshes with a gear 47b fixed to one end of the input shaft 58. A pulley 48a is fixed to the other end of the input shaft 58, and the pulley 48a and a pulley 48b fixed to the drive shaft 34 of the dust outlet processing cylinder 22 are wound around a belt 57.
In this way, the drive shaft 34 of the dust port processing cylinder 22 is interlocked to the drive shaft 34 of the dust port processing cylinder 22 via the pulleys 48a and 48b, the belt 57, and the gears 47a and 47b. Power is transmitted from 34 to the drive shaft 55 of the carrier 50 so that the carrier 50 can be driven to rotate in accordance with the rotation of the dust port processing cylinder 22.
However, the drive configuration of the transport body 50 is not limited, and may be a chain type or the like, and may be configured to transmit power not only from the dust outlet processing cylinder 22 but also from a lower sorting device or the like. You can also.

ここで、前記搬送体50の駆動軸55は、図10に示す如く、正面視で搬送体50が扱胴21の左側に設置されている場合、反時計回りに回転駆動するように構成されている。このようにしてスクリュー53と羽根56の回転方向を反時計回り方向とすることで、該スクリュー53により搬送された処理物は、羽根56によって揺動選別装置27上にアンダースローで排出されることになり、該処理物を受桶52の排出部52aから揺動選別装置27のチャフシーブ33等にたたきつけることなく排出することができる。
なお、本実施例においては、処理物は排出部52aから揺動選別装置27上にアンダースローで排出されるが、スクリュー53と羽根56を時計回りに回転駆動させて、処理物をオーバースローで排出するように構成することもできる。
Here, as shown in FIG. 10, the drive shaft 55 of the carrier 50 is configured to rotate counterclockwise when the carrier 50 is installed on the left side of the handling cylinder 21 in a front view. I have. By setting the rotation direction of the screw 53 and the blade 56 in the counterclockwise direction in this way, the processed material conveyed by the screw 53 is discharged by the blade 56 onto the swinging sorting device 27 in an underslow. Thus, the processed material can be discharged from the discharge portion 52a of the receiving tub 52 without hitting the chaff sheave 33 or the like of the swing sorting device 27.
In the present embodiment, the processed material is discharged from the discharge unit 52a onto the swing sorting device 27 in an underslow. However, the screw 53 and the blade 56 are rotated clockwise to discharge the processed material in the overslow. It can also be configured to do so.

このように構成することによって、送塵口処理胴22から処理胴網24を介して洩れ落ちて、処理物が搬送体50に落下すると、該処理物はスクリュー53の回転によって搬送体50の搬送終端部である排出部52aまで搬送されて、該排出部52aから羽根56の回転により揺動選別装置27の左右中心側へ排出されるのである。
したがって、送塵口処理胴22から直接二番コンベア37に落下することがなくなり、二番物は分散されて揺動選別装置27上に還元されるようになり、揺動選別装置27の選別幅を有効に活用して搬送した処理物を再選別し、穀粒ロスを低減するとともに、穀粒の処理の増加を図ることができる。
With this configuration, when the processing object is leaked from the dust outlet processing cylinder 22 via the processing drum network 24 and the processing object is dropped onto the conveyance body 50, the processing object is transported by the rotation of the screw 53. The sheet is conveyed to the discharge section 52a, which is the terminal end, and is discharged from the discharge section 52a to the left and right center sides of the swing sorting device 27 by the rotation of the blades 56.
Therefore, the dust is not dropped directly from the dust port processing cylinder 22 to the second conveyor 37, and the second articles are dispersed and returned to the swing sorting device 27, and the sorting width of the swing sorting device 27 is reduced. The reprocessed material conveyed by effectively utilizing is re-sorted to reduce grain loss and increase grain processing.

次に、第二実施例について説明する。
図11及び図12に示す如く、前記処理室29において、送塵口処理胴22の下方に搬送体60が、送塵口処理胴22と平面視で重複するように平行に前後方向に横設されている。該搬送体60は処理室29の下部に前後方向に正面視で漏斗状の受桶62を横設して上方を開放し、該受樋62内にスクリュー63を備えてコンベアを構成しており、該搬送体60はその搬送終端部(機体進行方向前側)が扱胴21の略中央部まで延設されて、搬送体60及び送塵口処理胴22の前方に配設された前記枝梗処理装置10に連結されている。
Next, a second embodiment will be described.
As shown in FIGS. 11 and 12, in the processing chamber 29, a transport body 60 is provided horizontally below the dust outlet processing cylinder 22 in the front-rear direction so as to overlap with the dust outlet processing cylinder 22 in a plan view. Have been. The transfer body 60 is provided with a funnel-shaped trough 62 in front of and below the processing chamber 29 in the front-rear direction and opened upward, and is provided with a screw 63 in the trough 62 to constitute a conveyor. The transfer end of the transfer body 60 (the front side in the machine body traveling direction) is extended to a substantially central portion of the handling drum 21, and the branch stem disposed in front of the transfer body 60 and the dust outlet processing cylinder 22. It is connected to the processing device 10.

そして、搬送体60によって、送塵口処理胴22から処理胴網24を介して落下する処理物を受け、該処理物を送塵口処理胴22による脱粒物の送り方向と反対方向である搬送終端部までスクリュー63の回転によって搬送して、枝梗処理装置10に投入し、該枝梗処理装置10内の枝梗処理胴11により枝梗を除去した後、揺動選別装置27の選別開始部に再投入する構成としている。   The carrier 60 receives the workpiece falling from the dust port processing cylinder 22 via the processing cylinder network 24, and transports the workpiece in the direction opposite to the direction in which the dust transported by the dust port processing cylinder 22 is transported. After being conveyed by the rotation of the screw 63 to the terminal end, it is put into the branch stalk processing apparatus 10, the branch stalk is removed by the branch stalk processing cylinder 11 in the branch stalk processing apparatus 10, and the sorting by the swing sorting apparatus 27 is started. It is configured to be re-input to the department.

また、図12に示す如く、前記搬送体60の搬送始端部(機体進行方向後側)には、二番還元コンベア80の後方上端部が連結されており、二番還元コンベア80から搬送される二番物を、搬送体60へ受け継ぎ、該搬送体60内をスクリュー63の回転によってその搬送終端部まで搬送して前記枝梗処理装置10に投入し、枝梗処理装置10内の枝梗処理胴11により枝梗を除去した後、揺動選別装置27の選別開始部に再投入する構成としている。   As shown in FIG. 12, the upper rear end of the second reduction conveyor 80 is connected to the transport start end (the rear side in the machine body traveling direction) of the transport body 60, and is transported from the second reduction conveyor 80. The second product is handed over to the carrier 60, and the inside of the carrier 60 is conveyed to the end of the conveyance by the rotation of the screw 63, and is introduced into the branch stalk processing apparatus 10, and the branch stalk processing in the branch stalk processing apparatus 10 is performed. After removing the branch stalks by the trunk 11, it is configured to be re-introduced into the sorting start portion of the rocking sorting device 27.

ここで、上述の如く前記搬送体60の搬送始端部に二番還元コンベア80を連結する構成とした場合、二番還元コンベア80は後方に傾斜して搬送体60の搬送始端部に連結されるため、従来の如く二番還元コンベアを前方に傾斜して枝梗処理装置に連結する場合に比べて、二番還元コンベア80の全長を短縮することができ、軽量化とコストの低減化を図ることができる。また、二番還元コンベア80は揚穀コンベア38とラップしないので、脱穀部12の横幅を短縮することができ、グレンタンク13の容量を増加したり、グレンタンク13の脱穀部12側の側板を簡素化したりすることができる。   Here, when the second reduction conveyor 80 is connected to the transport start end of the transport body 60 as described above, the second reduction conveyor 80 is inclined backward and is connected to the transport start end of the transport body 60. Therefore, compared with the conventional case where the second reduction conveyor is inclined forward and connected to the branch stalk processing apparatus, the overall length of the second reduction conveyor 80 can be reduced, and the weight and cost can be reduced. be able to. Further, since the second reduction conveyor 80 does not wrap with the lifting conveyor 38, the width of the threshing unit 12 can be reduced, the capacity of the Glen tank 13 can be increased, and the side plate of the Glen tank 13 on the threshing unit 12 side can be removed. Or it can be simplified.

なお、本実施例においては、搬送体60は枝梗処理装置10内の枝梗処理胴11と同軸上に配置されているが、図13に示す如く、搬送体60を前上がりに傾斜して、該搬送体60の搬送終端部の下方に枝梗処理装置10を配置し、搬送される処理物を枝梗処理胴11の上方から投入するように構成することもできる。   In the present embodiment, the transport body 60 is disposed coaxially with the branch incision processing cylinder 11 in the branch incision processing apparatus 10, but as shown in FIG. 13, the transport body 60 is inclined upward and forward. Alternatively, it is also possible to arrange the branch stalk processing device 10 below the transfer end portion of the transfer body 60 so that the processed material to be transferred is loaded from above the branch stalk processing cylinder 11.

このような構成において、枝梗の多い二番物と送塵口処理胴22の処理物を、二番還元コンベア80と搬送体60とからなる一経路で枝梗処理装置10に投入して枝梗を除去することができるため、効率よく枝梗処理を行うことができ、第一実施例と比較して、部品点数を低減することができる。また、送塵口処理胴22よる処理物には、稈切れも多いが、これを枝梗処理装置10で粉砕することができるため、選別能力の向上を図ることができる。   In such a configuration, the second product having many branch stalks and the processed material of the dust outlet processing cylinder 22 are fed into the branch stalk processing apparatus 10 through one path including the second reduction conveyor 80 and the carrier 60, and the branch is processed. Since the stalk can be removed, the branch stalk processing can be performed efficiently, and the number of parts can be reduced as compared with the first embodiment. Further, although there are many culm breaks in the processed material by the dust outlet processing cylinder 22, the culm can be crushed by the branch stalk processing apparatus 10, so that the sorting ability can be improved.
