特開２０１５−６２４２７号公報Japanese Patent Laying-Open No. 2015-62427

脱穀装置の扱き処理部における後部では、単粒化した穀粒が切れワラなどの塵埃と共に存在しがちとなるので、扱き処理部における後部の上方に位置する送塵弁どうしの間隔を狭くすることにより、送塵弁間における塵埃などの流動速度をあまり速くならないように抑制でき、穀粒が塵埃と共に脱穀装置の外部へ排出される穀粒損失を抑制し易い。
従来の技術を基に、穀粒損失の抑制を図りつつ送塵弁を設けた場合、脱穀装置の扱き処理部における前部の上方に位置する送塵弁どうしの間隔が、扱き処理部における後部の上方に位置する送塵弁どうしの間隔と同様に狭くなり、次の如き問題が生じる虞がある。
扱き処理部の前部では、刈取穀稈の全稈が投入されることや、刈取穀稈の脱穀処理が未だ十分でないことなどに起因して多量かつ嵩高の脱穀処理物が存在する傾向にあるので、送塵弁間における脱穀処理物の流れが悪くなる。脱穀処理物が流れ難くなれば、詰まりが発生し易くなる。また、刈取穀稈が脱穀途中の状態にあり、扱き処理部の前部における脱穀負荷が大きくなる傾向にあるので、扱き処理部の前部における脱穀処理物の流れが悪くなれば、扱き処理部の前部における脱穀負荷が大きくなる。 In the rear part of the handling unit of the threshing device, a single grain tends to be present along with dust such as broken straw, so the interval between the dust feeding valves located above the rear part in the handling unit should be reduced. Thus, the flow rate of dust and the like between the dust delivery valves can be suppressed so as not to be so high, and it is easy to suppress the grain loss in which the grains are discharged together with the dust to the outside of the threshing apparatus.
Based on conventional technology, when a dust feed valve is provided while suppressing grain loss, the distance between the dust feed valves located above the front part of the handling unit of the threshing device is the rear part of the handling unit. Like the interval between the dust delivery valves located above, the following problems may occur.
In the front part of the handling section, there is a tendency that a large amount and a bulky threshing product exist due to the fact that the whole grain of the harvested cereal meal is introduced and the threshing process of the harvested grain meal is not yet sufficient. Therefore, the flow of the threshing processed material between the dust feeding valves becomes worse. If the threshing product becomes difficult to flow, clogging is likely to occur. In addition, since the harvested culm is in the middle of threshing and the threshing load at the front part of the handling unit tends to increase, if the flow of the threshing product in the front part of the handling unit becomes worse, the handling unit The threshing load at the front of is increased.

本発明は、上記した穀粒損失を抑制できるのみならず、脱穀処理物の詰まりや脱穀負荷の増大を回避し易いコンバインを提供する。   The present invention not only can suppress the above-described grain loss, but also provides a combine that is easy to avoid clogging of threshing products and an increase in threshing load.

本発明によるコンバインは、次の如き構成を備えている。
刈取穀稈を搬送するフィーダと、
前記フィーダによって刈取穀稈の全稈が投入され、投入された刈取穀稈を扱き処理する脱穀装置と、を備え、
前記脱穀装置に、扱室に回転駆動可能に設けられた扱胴と、前記扱室の天板に、前記扱胴の回転軸芯に沿う方向に並ぶ状態で支持され、脱穀処理物を前記扱室の後方へ向けて送り案内する複数の送塵弁と、が備えられ、
前記扱胴の前部に、螺旋羽根を有すると共に前記螺旋羽根の回転によって穀稈を前記扱胴の後部側に掻き込む掻込み部が備えられ、
前記扱胴における前記掻込み部の後側に扱き処理部が備えられ、
前記扱き処理部の前部の上方に位置する前記送塵弁どうしの間隔が、前記扱き処理部の後部の上方に位置する前記送塵弁どうしの間隔より広い、という構成を備えている。 The combine according to the present invention has the following configuration.
A feeder for transporting the harvested cereal meal;
A whole threshing of the harvested cereal meal is introduced by the feeder, and a threshing device for handling and processing the introduced harvested grain meal,
The threshing device is supported by a handling cylinder provided rotatably in the handling chamber and a top plate of the handling chamber in a state of being aligned in a direction along the rotation axis of the handling cylinder, and the processed threshing product is A plurality of dust feeding valves for feeding and guiding toward the rear of the chamber,
At the front part of the barrel, a spiral blade is provided, and a scraping portion for scraping the cereal into the rear side of the barrel by rotation of the spiral blade is provided,
A handling unit is provided on the rear side of the scraping unit in the handling cylinder,
It has a configuration in which the interval between the dust delivery valves located above the front part of the handling unit is wider than the interval between the dust delivery valves located above the rear part of the handling unit.

本構成によると、扱き処理部の後部においては、送塵弁間における脱穀処理物の流動速度があまり速くならないように、扱き処理部の後部の上方に位置する送塵弁どうしの間隔を適切な広さの間隔に設定しても、扱き処理部の前部の上方に位置する送塵弁どうしの間隔が、扱き処理部の後部の上方に位置する送塵弁どうしの間隔より広いので、扱き処理部の前部においては、脱穀処理物が広い間隔の送塵弁間をスムーズに流動し、送塵弁間に滞留せずに扱室の広い範囲に分散するようにできる。   According to this configuration, in the rear part of the handling unit, the interval between the dust feeding valves located above the rear part of the handling unit is appropriately set so that the flow rate of the threshing product between the dust feeding valves is not so high. Even if the space interval is set, the interval between the dust delivery valves located above the front of the handling unit is wider than the interval between the dust delivery valves located above the rear of the handling unit. In the front part of the processing unit, the threshing product can smoothly flow between the dust feeding valves at a wide interval, and can be dispersed in a wide range of the handling chamber without staying between the dust feeding valves.

従って、扱き処理部の後部において穀粒が塵埃と共に流動して脱穀装置の外部に流出する穀粒損失を抑制できるのみならず、扱き処理部の前部において、脱穀処理物の量が多いとか嵩が高いとかの状態にあっても、脱穀処理物を広範囲に分散させて、詰まりを発生し難くできると共に脱穀負荷をあまり高負荷にならないように抑制でき、能率よく脱穀処理できる。   Therefore, not only can the grain loss flow at the rear part of the handling unit with dust and flow out of the threshing apparatus, but also the amount of threshing processed material is large or bulky at the front part of the handling unit. Even if it is in a high state, it is possible to disperse the threshing products over a wide range, make clogging less likely to occur, and suppress the threshing load from becoming too high, thereby efficiently performing the threshing treatment.

本発明をより好適なものにするよう、次の如き構成を備えた。
前記扱き処理部の前部の上方に位置する複数の前記送塵弁のうち、前記扱き処理部の前から１番目の送塵弁と２番目の送塵弁との間隔が、前記扱き処理部の後部の上方に位置する前記送塵弁どうしの間隔より広い、という構成を備えた。 In order to make the present invention more suitable, the following configuration is provided.
Among the plurality of dust delivery valves positioned above the front part of the handling unit, the interval between the first and second dust feeding valves from the front of the handling unit is the handling unit. A configuration is provided that is wider than the interval between the dust delivery valves located above the rear part.

扱き処理部の前から１番目の送塵弁と２番目の送塵弁との間を流動する脱穀処理物は、扱き処理の受け始めであって、嵩が高い状態にある。本構成によれば、１番目の送塵弁と２番目の送塵弁との間隔が扱き処理部の後部の上方に位置する送塵弁どうしの間隔より広いので、脱穀処理物は、嵩高にかかわらず、１番目の送塵弁と２番目の送塵弁との間をスムーズに流動し、脱穀処理物を扱室の後方へ向けてスムーズに流動させることができる。   The threshing processed material that flows between the first dust feeding valve and the second dust feeding valve from the front of the handling processing unit has started to receive the handling processing and is in a bulky state. According to this structure, since the space | interval of the 1st dust feeding valve and the 2nd dust feeding valve is wider than the space | interval of the dust feeding valves located above the rear part of a processing part, a threshing processed material becomes bulky. Regardless, it is possible to smoothly flow between the first dust delivery valve and the second dust delivery valve, and to smoothly flow the threshing processed product toward the rear of the handling chamber.

本発明をより好適なものにするよう、次の如き構成を備えた。
前記１番目の送塵弁は、前記掻込み部と前記扱き処理部との境界部の上方において、平面視で前記掻込み部と前記扱き処理部とに跨る状態で設けられている、という構成を備えた。 In order to make the present invention more suitable, the following configuration is provided.
The first dust delivery valve is provided above the boundary portion between the scraping portion and the handling processing portion so as to straddle the scraping portion and the handling processing portion in a plan view. Equipped with.

本構成によれば、刈取穀稈が掻込み部による掻き込みを受けつつ、１番目の送塵弁による送り案内を受けるので、全稈にわたって扱室に投入される刈取穀稈を扱き処理部へスムーズに導入できる。   According to this configuration, the harvested cereal rice cake receives the feed guidance by the first dust feed valve while receiving the scraping by the scoring unit, so that the harvested cereal rice cake that is thrown into the handling room over the whole straw is sent to the handling processing unit It can be introduced smoothly.

本発明をより好適なものにするよう、つぎの如き構成を備えた。
前記扱き処理部の前部の上方に位置する複数の前記送塵弁のうち、前記扱き処理部の前から２番目の送塵弁と３番目の送塵弁との間隔が、前記扱き処理部の後部の上方に位置する前記送塵弁どうしの間隔より広い、という構成を備えた。 In order to make the present invention more suitable, the following configuration is provided.
Among the plurality of dust delivery valves positioned above the front part of the handling unit, the interval between the second and third dust feeding valves from the front of the handling unit is the handling unit. A configuration is provided that is wider than the interval between the dust delivery valves located above the rear part.

扱き処理部の前から２番目の送塵弁と３番目の送塵弁との間を流動する脱穀処理物は、扱き処理の途中であって、まだ嵩が高い状態にある。本構成によれば、２番目の送塵弁と３番目の送塵弁との間隔が扱き処理部の後部の上方に位置する送塵弁どうしの間隔より広いので、脱穀処理物は、嵩高にかかわらず、２番目の送塵弁と３番目の送塵弁との間をスムーズに流動し、脱穀処理物を扱室の後方へ向けてスムーズに流動させることができる。   The threshing processed product flowing between the second dust feeding valve and the third dust feeding valve from the front of the handling processing unit is in the middle of the handling processing and is still in a bulky state. According to this configuration, since the interval between the second dust delivery valve and the third dust delivery valve is wider than the interval between the dust delivery valves located above the rear part of the handling unit, the threshing processed product is bulky. Regardless, it is possible to smoothly flow between the second dust feeding valve and the third dust feeding valve, and to smoothly flow the threshing processed product toward the rear of the handling chamber.

本発明をより好適なものにするよう、つぎの如き構成を備えた。
前記扱き処理部に、前記扱胴の回転軸芯上に配置された支軸と、棒状であり、前記回転軸芯に沿った姿勢で、前記扱胴の周方向に間隔を空けて設けられた複数の扱歯支持部材と、棒状であり、前記扱胴の径方向外側に向けて突出する状態で、前記扱歯支持部材に、前後方向に間隔を空けて設けられた複数の扱歯と、前記支軸に前記回転軸芯に沿う方向に並ぶ状態で支持され、前記複数の扱歯支持部材の中間部を支持する複数の板状部材と、が備えられ、
前記２番目の送塵弁は、複数の前記板状部材のうちの前記扱き処理部の前部に位置する前部側板状部材の上方において、平面視で前記前部側板状部材の前後に跨る状態で設けられており、
前記３番目の送塵弁は、複数の前記板状部材のうち、前記前部側板状部材の後に当該前部側板状部材に隣り合って位置する隣接板状部材の上方において、平面視で前記隣接板状部材の前後に跨る状態で設けられている、という構成を備えた。 In order to make the present invention more suitable, the following configuration is provided.
A support shaft disposed on the rotation axis of the handling cylinder and a rod-like shape are provided in the handling processing unit, and provided in a posture along the rotation axis and spaced in the circumferential direction of the handling cylinder. A plurality of tooth-handling support members, a rod-like shape, and a plurality of teeth-handling provided at intervals in the front-rear direction on the tooth-handling support member in a state of projecting toward the radially outer side of the treatment barrel; A plurality of plate-like members that are supported on the support shaft in a state along the rotation axis and that support intermediate portions of the plurality of tooth-supporting members; and
The second dust feeding valve extends across the front and rear plate-like members in plan view above the front-side plate-like member located at the front portion of the handling processing portion among the plurality of plate-like members. Provided in the state,
The third dust feeding valve is, in plan view, above the adjacent plate member positioned adjacent to the front plate member after the front plate member among the plurality of plate members. It has a configuration in which it is provided in a state straddling the front and rear of the adjacent plate-like member.

本構成によれば、掻込み部からの脱穀処理物を、扱き処理部と受網との間に導入する。扱胴は、扱胴の外部に位置する脱穀処理物に扱歯支持部材及び扱歯による打撃や扱歯の梳き込みなどによる脱穀処理を施す。殊に処理物量が多い場合、掻込み部からの処理物が扱歯支持部材の間を介して扱胴の内部空間へ入り込むことを許容し、処理物の詰まりを防止できる。内部空間に入った処理物は、撹拌によって脱穀処理され、遠心力によって扱歯支持部材の間から外部へ出る。   According to this structure, the threshing processed material from the scraping unit is introduced between the handling processing unit and the receiving net. The treatment cylinder performs a threshing process on the threshing processed material located outside the treatment cylinder by striking with the tooth handling support member and the tooth handling or swallowing the tooth handling. In particular, when the amount of processed material is large, it is possible to allow the processed material from the scraping portion to enter the internal space of the handle cylinder through the tooth support member, and to prevent clogging of the processed material. The processed material that has entered the internal space is threshed by agitation and exits from between the tooth support members by centrifugal force.

扱胴の外部に位置する処理物は、掻込み部の螺旋羽根によって供給される風や、２番目の送塵弁による送り案内を受け、前部側板状部材を前側から後側へ超えて扱胴の後方へ向けてスムーズに流動し、３番目の送塵弁による送り案内を受け、隣接板状部材を前側から後側へ超えて扱胴の後方へ向けてスムーズに流動する。この処理物流動に伴い、扱胴の内部空間に位置する処理物が遠心力によって扱歯支持部材の間を介して扱胴の外部へ流出し、前部側板状部材や隣接板状部材を前側から後側へ超えて扱胴の後方へ向けて流動する。   The processing object located outside the handling cylinder receives the wind supplied by the spiral blade of the scraping part and the feed guidance by the second dust feed valve, and handles the front side plate-like member beyond the front side to the rear side. It smoothly flows toward the rear of the cylinder, receives a feed guide by the third dust supply valve, and smoothly flows from the front side to the rear side of the adjacent plate member toward the rear side of the handling cylinder. Along with the flow of the processed material, the processed material located in the inner space of the handling cylinder flows out of the handling cylinder through the space between the tooth handling support members by centrifugal force, and the front side plate-like member and the adjacent plate-like member are moved to the front It flows to the rear side of the handling cylinder beyond the rear side.

従って、扱室に投入された全稈にわたる刈取穀稈、及び多量の刈取穀稈に扱き作用を適確に付与できると共に脱穀処理物を扱室の後方へ向けてスムーズに流動させることができ、刈取穀稈を適確にかつ能率よく脱穀処理できる。   Therefore, it is possible to accurately give a handling action to the whole harvested cereal mash that has been put into the handling room, and a large amount of the harvested cereal meal, and to smoothly flow the threshing processed product toward the rear of the handling room, Threshing can be done accurately and efficiently.

本発明をより好適なものにするよう、つぎの如き構成を備えた。
前記天板の前後中央部の直前部位に位置する前記送塵弁どうしの間隔が、前記天板の前記前後中央部以後における部位に位置する前記送塵弁どうしの間隔より広い、という構成を備えた。 In order to make the present invention more suitable, the following configuration is provided.
The interval between the dust feeding valves located immediately before the front and rear central portion of the top plate is wider than the interval between the dust feeding valves located at the portion after the front and rear central portion of the top plate. It was.

天板の前後中央部の直前部位に位置する送塵弁どうしの間に位置する脱穀処理物は、扱き処理の途中であって、まだ嵩が高い状態にある。本構成によれば、天板の前後中央部の直前部位に位置する送塵弁どうしの間隔が、天板の前後中央部以後における部位に位置する送塵弁どうしの間隔より広いので、脱穀処理物は、嵩高にかかわらず、送塵弁間をスムーズに流動し、脱穀処理物を扱室の後方へ向けてスムーズに流動させることができる。   The threshing processed product located between the dust feeding valves located immediately before the front and rear central portions of the top plate is in the middle of the handling treatment and is still in a bulky state. According to this configuration, the threshing treatment is performed because the interval between the dust feeding valves located in the immediately preceding center portion of the top plate is wider than the interval between the dust feeding valves located in the portion after the center portion of the top plate. Regardless of the bulkiness, the product can smoothly flow between the dust feeding valves, and the threshing product can smoothly flow toward the rear of the handling chamber.

本発明をより好適なものにするよう、つぎの如き構成を備えた。
前記天板のうち、前記扱き処理部の前後中央部に対応する位置の直前部位に位置する前記送塵弁どうしの間隔が、前記天板のうち、前記扱き処理部の前後中央部に対応する位置以後の部位に位置する前記送塵弁どうしの間隔より広い、という構成を備えた。 In order to make the present invention more suitable, the following configuration is provided.
Among the top plates, an interval between the dust delivery valves located immediately before a position corresponding to the front / rear center portion of the handling processing unit corresponds to the front / rear center portion of the handling processing portion of the top plate. The configuration is such that it is wider than the interval between the dust delivery valves located at the position after the position.

天板のうち、扱き処理部の前後中央部に対応する位置の直前部位に位置する送塵弁どうしの間に位置する脱穀処理物は、扱き処理の途中であって、まだ嵩が高い状態にある。本構成によれば、天板のうち、扱き処理部の前後中央部に対応する部位に位置する送塵弁どうしの間隔が、天板のうち、扱き処理部の前後中央部に対応する部位以後に位置する送塵弁どうしの間隔より広いので、脱穀処理物は、嵩高にかかわらず、送塵弁間をスムーズに流動し、脱穀処理物を扱室の後方へ向けてスムーズに流動させることができる。   Of the top plate, the threshing product located between the dust-feeding valves located immediately before the position corresponding to the front-rear center part of the handling unit is in the middle of the handling process and still in a bulky state. is there. According to this configuration, among the top plates, the interval between the dust-feeding valves located in the portions corresponding to the front and rear central portions of the handling processing unit is the portion of the top plate corresponding to the front and rear central portions of the handling processing portion. Therefore, the threshing product can flow smoothly between the dusting valves regardless of the bulkiness, and the threshing product can flow smoothly toward the rear of the handling chamber. it can.

本発明をより好適なものにするよう、つぎの如き構成を備えた。
前記天板は、前記扱胴の回転軸芯に沿う方向視で、上方に向かって突出する弧状の断面形状であり、前記天板に、送り案内角が前記送塵弁の送り案内角より緩傾斜角である別の送塵弁を前記送塵弁に替えて取り付ける支持部が設けられている、という構成を備えた。 In order to make the present invention more suitable, the following configuration is provided.
The top plate has an arcuate cross-sectional shape protruding upward as viewed in the direction along the rotation axis of the barrel, and the top plate has a feed guide angle that is less than the feed guide angle of the dust feed valve. A structure is provided in which a support portion is provided for attaching another dust feeding valve having an inclination angle in place of the dust feeding valve.

本構成によると、送塵弁に替えて別の送塵弁を取り付けることにより、脱穀処理物が送塵弁の送り案内角より緩傾斜角の送り案内角によって送り案内されるので、扱室の後方へ向かう脱穀処理物の流動が低速側になる。このように脱穀処理物の流動が低速側になっても、天板の断面形状が上方に向かって突出する弧状であるので、脱穀処理物が天板によってあまり大きな流動抵抗を受けずに移動する。
つまり、穀稈の品質相違等によっては、送塵弁に替えて別の送塵弁を取り付けることにより、扱室の後方へ向かう脱穀処理物の流動を低速側に調節できる。低速側に調節しても脱穀処理物を扱室の後方へ向けてスムーズに流動させて、適確かつ能率よく脱穀処理できる。 According to this configuration, by attaching another dust feed valve instead of the dust feed valve, the processed threshing material is fed and guided by a feed guide angle that is gentler than the feed guide angle of the dust feed valve. The flow of the processed threshing product toward the rear is on the low speed side. Thus, even if the flow of the threshing product is on the low speed side, the cross-sectional shape of the top plate is an arc shape protruding upward, so that the threshing product moves without receiving a large flow resistance by the top plate. .
In other words, depending on the quality difference of the cereals, the flow of the threshing product toward the rear of the handling chamber can be adjusted to the low speed side by attaching another dust feeding valve instead of the dust feeding valve. Even if it adjusts to the low speed side, the threshing processed material can be smoothly flowed toward the rear of the handling room, and the threshing treatment can be performed accurately and efficiently.

本発明をより好適なものにするよう、つぎの如き構成を備えた。
前記天板のうち、前記扱き処理部の前部の上方に位置する前記送塵弁どうしの間の部位に、送り案内角が前記送塵弁の送り案内角より緩傾斜角である増設用の送塵弁を取り付ける支持部が設けられている、という構成を備えた。 In order to make the present invention more suitable, the following configuration is provided.
Of the top plate, for the extension between the dust feed valves located above the front portion of the handling processing unit, the feed guide angle is a gentler inclination angle than the feed guide angle of the dust feed valve The structure which the support part which attaches a dust feeding valve was provided was provided.

送塵弁に替えて別の送塵弁を取り付けた場合、扱き処理部の前部の上方において、送り案内角が緩傾斜角である別の送塵弁が広い間隔を隔てて並ぶことになる。本構成によると、増設用の送塵弁を取り付けることにより、別の送塵弁の送り案内角と同じ送り案内角を有するとか、別の送塵弁の送り案内角とあまり相違しない送り案内角を有するとかの送塵弁機能を別の送塵弁どうしの間に設け、間隔が広い別の送塵弁どうしの間に、増設用の送塵弁によって送り案内機能を補足できる。つまり、別の送塵弁を取り付け、扱室の後方へ向かう脱穀処理物の流動を低速側に調節しても、脱穀処理物を扱室の後方へ向けてスムーズに流動させて、適確かつスムーズに脱穀処理できる。   When another dust delivery valve is installed instead of the dust delivery valve, another dust delivery valve whose feed guide angle is a gentle inclination angle is arranged at a wide interval above the front part of the handling unit. . According to this configuration, by installing an additional dust feed valve, the feed guide angle has the same feed guide angle as that of another dust feed valve, or is not very different from the feed guide angle of another dust feed valve. It is possible to supplement the feed guide function by providing an additional dust feed valve between the other dust feed valves having a wide interval. In other words, even if another dust-feeding valve is installed and the flow of the threshing processed product toward the rear of the handling chamber is adjusted to the low speed side, the threshing processed product flows smoothly toward the rear of the handling chamber and is accurate. Threshing can be done smoothly.

本発明をより好適なものにするよう、つぎの如き構成を備えた。
前記掻込み部に、前記扱胴の前端側ほど小径である先細り形状を有した基台部が備えられ、前記螺旋羽根は、前記基台部の外周部に立設されており、前記螺旋羽根の終端側部における外周部と前記扱胴の回転軸芯との径方向での距離は、前記螺旋羽根の始端側部における外周部と前記扱胴の回転軸芯との径方向での距離より小さいという構成を備えた。 In order to make the present invention more suitable, the following configuration is provided.

前記螺旋羽根の搬送面に脱着可能なライナー部材を備え、前記螺旋羽根の終端側部における外周部と前記扱胴の回転軸芯との径方向での距離は、前記螺旋羽根の始端側部における外周部と前記扱胴の回転軸芯との径方向での距離より小さく、前記ライナー部材を前記螺旋羽根に取付けた状態において、前記ライナー部材の外周部と前記扱胴の回転軸芯との径方向での距離は、前記螺旋羽根の外周部と前記扱胴の回転軸芯との径方向での距離より大きく、且つ、前記ライナー部材の始端側部から前記ライナー部材の終端側部に亘って、前記ライナー部材の外周部と前記扱胴の回転軸芯との径方向での距離は、同一であるという構成を備えた。 In order to make the present invention more suitable, the following configuration is provided.
A liner member that can be attached to and detached from the conveying surface of the spiral blade is provided, and the radial distance between the outer peripheral portion at the terminal side of the spiral blade and the rotational axis of the handling cylinder is at the start side of the spiral blade. The diameter of the outer peripheral part of the liner member and the rotational axis of the handling cylinder is smaller than the distance in the radial direction between the outer peripheral part and the rotational axis of the handling cylinder and the liner member is attached to the spiral blade. The distance in the direction is larger than the distance in the radial direction between the outer peripheral portion of the spiral blade and the rotational axis of the handling cylinder, and extends from the start end side portion of the liner member to the end side portion of the liner member. The distance in the radial direction between the outer peripheral portion of the liner member and the rotational axis of the handling cylinder is the same.

本構成によれば、螺旋羽根にライナー部材を取り付けることにより、螺旋羽根は、螺旋羽根の搬送面がライナー部材によって覆われた状態で処理物を掻き込み搬送する。螺旋羽根では、終端側部における外周部が始端側部における外周部に対して扱胴回転軸芯が位置する側に位置ずれしている。ライナー部材では、ライナー部材の外周部と扱胴の回転軸芯との径方向での距離は、螺旋羽根の外周部と扱胴の回転軸芯との径方向での距離より大きく、且つ、ライナー部材の始端側部からライナー部材の終端側部に亘って、ライナー部材の外周部と扱胴の回転軸芯との径方向での距離が同一であるので、螺旋羽根にライナー部材を取り付けることにより、螺旋羽根だけで掻き込み搬送する場合より広い搬送面によって処理物を適確に掻込み搬送できる。   According to this configuration, by attaching the liner member to the spiral blade, the spiral blade scrapes and transports the processed material in a state where the transport surface of the spiral blade is covered with the liner member. In the spiral blade, the outer peripheral portion at the terminal end side is displaced from the outer peripheral portion at the start end side to the side where the handling cylinder rotation axis is located. In the liner member, the radial distance between the outer peripheral portion of the liner member and the rotational axis of the handling cylinder is greater than the radial distance between the outer peripheral portion of the spiral blade and the rotational axis of the handling cylinder, and the liner Since the radial distance between the outer periphery of the liner member and the rotational axis of the barrel is the same from the starting end side of the member to the terminal end side of the liner member, the liner member is attached to the spiral blade. In addition, the processed material can be properly scraped and conveyed by a wider conveying surface than when it is scraped and conveyed only by the spiral blade.

本発明をより好適なものにするよう、つぎの如き構成を備えた。
前記螺旋羽根の前端縁が、前記基台部の外周面に対して前記基台部の径方向外側に離れるほど搬送方向下手側に位置する状態で前記外周面に対して傾斜しており、
前記ライナー部材を前記螺旋羽根に取付けた状態において、前記ライナー部材の前端部が前記螺旋羽根の前記前端縁から搬送方向上手側に突出し、且つ、前記ライナー部材の前端縁が前記外周面から前記基台部の径方向外側に立ち上がると共に前記外周面から前記基台部の径方向外側に離れるほど前記螺旋羽根の前端縁に対して搬送方向上手側に離れるという構成を備えた。 In order to make the present invention more suitable, the following configuration is provided.
The front edge of the spiral blade is inclined with respect to the outer peripheral surface in a state where the front end edge of the spiral blade is located on the lower side in the conveying direction as it is separated from the outer peripheral surface of the base portion in the radial direction,

A configuration is provided in which the outer edge rises in the radial direction of the base part and is further away from the outer peripheral surface toward the outer side of the base part in the radial direction of the base part.

本構成によれば、螺旋羽根にライナー部材を取り付けることにより、ライナー部材の前端縁が、螺旋羽根の前端縁に代わって、刈取穀稈に掻込み作用する。螺旋羽根の前端縁は、基台部の外周面から基台部の径方向外側に離れるほど螺旋羽根の前端縁に対して搬送方向上手側に離れる状態で基台部の外周面から立ち上がるので、ライナー部材を取り付けることにより、ライナー部材が前端縁によって穀稈を掻込む際、穀稈がライナー部材から外れ難く、刈取穀稈を適確に掻込み導入させることができる。   According to this configuration, by attaching the liner member to the spiral blade, the front end edge of the liner member acts on the harvested cereal meal instead of the front end edge of the spiral blade. Since the front end edge of the spiral blade rises from the outer peripheral surface of the base portion in a state of being separated from the front end edge of the spiral blade toward the upper side in the transport direction as it moves away from the outer peripheral surface of the base portion in the radial direction, By attaching the liner member, when the liner member scoops the cereal with the front edge, the cereal is difficult to come off from the liner member, and the harvested cereal can be introduced appropriately.
