また、株元ガイド部４８の基端側は、その左右両側を上方に立ち上がるように屈曲することにより前側固定部５１（立ち上がり部）が形成されており、前側固定部５１には、倒伏部材４３の前側を取付支持するための前後一対の取付孔５１ａが左右にそれぞれ穿設されている。 Further, the base end side of the stock base guide portion 48 is bent so as to stand up on both the left and right sides thereof to form a front side fixing portion 51 (rising portion), and the front side fixing portion 51 is formed with a lodging member 43. A pair of front and rear mounting holes 51a for mounting and supporting the front side of the vehicle are bored on the left and right sides, respectively.

このような構成によれば、ガイド部材４２は、刈取装置１６側から前方上方に向かつて延設され、その先端側が徐々に幅狭となる鋭角状に形成されたことによって、刈取装置１６によって刈取られる圃場の穀稈は、隣接するガイド部材４２の間に順次案内されるため、倒伏部材４３による穀稈の倒伏と、刈取装置１６による穀稈の刈り取りとを詰まりなくスムーズに行うことができる。 According to such a configuration, the guide member 42 is extended forward and upward from the cutting device 16 side, and the tip side thereof is formed into an acute-angled shape that gradually narrows, so that the cutting device 16 cuts. Since the grain culms in the field are sequentially guided between the adjacent guide members 42, the lodging of the grain culms by the lodging member 43 and the cutting of the grain culms by the cutting device 16 can be smoothly performed without clogging.

また、ガイド部材４２は、刈取部３がリフトシリンダ１０によって最下降位置から前方上方に向けて押上げるようにして上昇作動するように構成されているため、刈取部３が最下降位置まで下降された状態では、ガイド部材４２が側面視で略水平な水平姿勢となる一方で、刈取部３が刈取作業を行う刈高さまで上昇作動された状態では、ガイド部材４２が側面視で前高後低の傾斜姿勢となるように構成されている。なお、ガイド部材４２の取付角度はこれに限られず、刈取部３が刈取高さまで上昇された場合に、水平姿勢となるように構成してもよい。 Further, since the guide member 42 is configured so that the cutting portion 3 is pushed up by the lift cylinder 10 from the lowest descending position toward the front and upper direction, the cutting portion 3 is lowered to the lowest lowering position. In this state, the guide member 42 is in a substantially horizontal horizontal posture in the side view, while in the state where the cutting unit 3 is raised to the cutting height at which the cutting work is performed, the guide member 42 is in the front height and the rear low in the side view. It is configured to be in an inclined posture. The mounting angle of the guide member 42 is not limited to this, and the guide member 42 may be configured to be in a horizontal posture when the cutting portion 3 is raised to the cutting height.

支持部４７は、後端側には左右中央に前方に向かつて凹設された凹設部４７ａが形成されている。また、支持部４７の左右両側には、左右両端が上方に立ち上がるアングル状部材であって、倒伏部材４３の後側が取付支持される一対の後側固定部５２（立ち上がり部）が溶着等で取付固定されており、後側固定部５２には、倒伏部材４３を取付けるための取付孔５２ａが穿設されている（図６等参照）。 The support portion 47 is formed with a recessed portion 47a that is recessed forward in the center of the left and right sides at the rear end side. Further, on both the left and right sides of the support portion 47, a pair of rear side fixing portions 52 (rising portions), which are angle-shaped members whose left and right ends rise upward and which support the rear side of the lodging member 43, are attached by welding or the like. It is fixed, and a mounting hole 52a for mounting the lodging member 43 is bored in the rear fixing portion 52 (see FIG. 6 and the like).

このような構成によれば、前側固定部５１と後側固定部５２とは、ガイド部材４２の左右両側に設けられているため、倒伏部材４２は、ガイド部材４２の左右両端のどちらにも取付けることができる。 According to such a configuration, since the front fixing portion 51 and the rear fixing portion 52 are provided on both the left and right sides of the guide member 42, the lodging member 42 is attached to both the left and right ends of the guide member 42. be able to.

すなわち、倒伏ガイド２１の左側に倒伏部材４３を取付ける場合と、倒伏ガイド２１の右側に倒伏部材４３を取付ける場合とで、同一形状のガイド部材４２を兼用して用いることができるため、部品点数の種類を削減して製造コストを低く抑えることができる。 That is, since the guide member 42 having the same shape can be used in combination between the case where the lodging member 43 is mounted on the left side of the lodging guide 21 and the case where the lodging member 43 is mounted on the right side of the lodging guide 21, the number of parts is increased. The number of types can be reduced to keep the manufacturing cost low.

［倒伏部材］
倒伏部材４３は、ガイド部材４２の左右側方側に取付けられる板状部材であって、前側固定部５１及び後側固定部５２に取付固定するための取付孔４３ａ、４３ｂ、４３ｃが前後方向に複数（図示する例では３箇所）並べて穿設されており、倒伏部材４３の上端側には、左右一方側、具体的には取付けられるガイド部材４２と反対側に向けて屈曲形成された屈曲部５３が形成されている。 [Falling member]
The lodging member 43 is a plate-shaped member attached to the left and right side of the guide member 42, and attachment holes 43a, 43b, 43c for attaching and fixing to the front fixing portion 51 and the rear fixing portion 52 are provided in the front-rear direction. A plurality of (three places in the illustrated example) are bored side by side, and a bent portion formed by bending toward the left and right one side, specifically, the side opposite to the guide member 42 to be attached, on the upper end side of the lodging member 43. 53 is formed.

屈曲部５３は、後方に向かつて徐々に幅広となるように形成されており、平面視で直角三角形状となるように構成されている（図３及び図６参照）。このとき、屈曲部５３の左右幅は、隣接して配置される倒伏ガイド２１同士の間の距離よりも短く、より具体的には、刈取装置１６の刈刃１６Ａの歯幅の半分程度となるように形成されている。 The bent portion 53 is formed so as to gradually widen toward the rear, and is configured to have a right-angled triangular shape in a plan view (see FIGS. 3 and 6). At this time, the left-right width of the bent portion 53 is shorter than the distance between the lodging guides 21 arranged adjacent to each other, and more specifically, it is about half the tooth width of the cutting blade 16A of the cutting device 16. It is formed like this.

ちなみに、屈曲部５３の左右幅は、隣接する倒伏ガイド２１に到達する範囲まで広く形成することにより、平面視で屈曲部５３の後端側が隣接する倒伏ガイド２１のガイド部材４２とラップするように構成してもよい。このような構成によれば、ガイド部材４２によって刈取装置１６の前方まで案内された穀稈の株元側をより確実に左右一方側へ倒伏させることができる。 By the way, the left-right width of the bent portion 53 is widened to the extent that it reaches the adjacent lodging guide 21, so that the rear end side of the bent portion 53 wraps with the guide member 42 of the adjacent lodging guide 21 in a plan view. It may be configured. According to such a configuration, the stock root side of the grain culm guided to the front of the cutting device 16 by the guide member 42 can be more reliably laid down on one of the left and right sides.

上述の倒伏ガイド２１は、刈取フレーム９（刈取装置１６）の左右幅全体に亘って左右方向に複数並べて設けられるとともに、左右方向に並べて配置される各倒伏ガイド２１同士の間は、刈取装置１６の刈刃１６Ａの歯幅程度の間隔を空けて取付けられている（図２等参照）。 A plurality of the above-mentioned lodging guides 21 are provided side by side in the left-right direction over the entire left-right width of the cutting frame 9 (cutting device 16), and the cutting device 16 is provided between the lodging guides 21 arranged side by side in the left-right direction. The cutting blades 16A are attached at intervals of about the tooth width (see FIG. 2 and the like).

また、倒伏ガイド２１は、刈取装置１６の右側半部に取付けられた倒伏部材４３は、屈曲部５３が左右左側に延設される方向に取付けられ、刈取装置１６の左側半部に取付けられた倒伏部材４３は、屈曲部５３が左右右側に延設される方向に取付けられるように構成されている。言い換えると、倒伏部材４３は、刈取られる圃場の穀稈を刈取部３の中心に向かう左右内側に倒伏させるように構成されている（図３参照）。 Further, in the lodging guide 21, the lodging member 43 attached to the right half of the cutting device 16 is attached in the direction in which the bent portion 53 extends to the left and right, and is attached to the left half of the cutting device 16. The lodging member 43 is configured so that the bent portion 53 is attached in a direction extending to the left and right. In other words, the lodging member 43 is configured to lay the culms of the field to be cut inward to the left and right toward the center of the cutting portion 3 (see FIG. 3).

具体的には、刈幅の略中心で、且つフィーダ入口寄りに配置された倒伏ガイド２１を中心ガイド２１Ｃとして設定し、各倒伏ガイド２１（倒伏部材４３）は、刈取穀稈を中心ガイド２１Ｃに向けて倒伏させるように設定されている（図３参照）。このとき、中心ガイド２１Ｃの位置は、ガイド部材４２に取付けられる倒伏部材４３を組み替えることによって容易に変更できるように構成されている。 Specifically, the lodging guide 21 located at the substantially center of the cutting width and near the feeder entrance is set as the center guide 21C, and each lodging guide 21 (falling member 43) uses the cut grain culm as the center guide 21C. It is set to lie down toward it (see FIG. 3). At this time, the position of the center guide 21C is configured so that it can be easily changed by rearranging the lodging member 43 attached to the guide member 42.

なお、中心ガイド２１Ｃは、刈幅の中心に配置された倒伏ガイド２１や、フィーダ９の左右中心に配置された倒伏ガイド２１を選択してもよい。ちなみに、図示する例では、左から５番目に配置された倒伏ガイド２１が左右方向の中心に配置された中心ガイド２１Ｃとして設定されている。 As the center guide 21C, a lodging guide 21 arranged at the center of the cutting width or a lodging guide 21 arranged at the left and right centers of the feeder 9 may be selected. By the way, in the illustrated example, the lodging guide 21 arranged at the fifth position from the left is set as the center guide 21C arranged at the center in the left-right direction.

すなわち、上述の構成の倒伏ガイド２１によれば、隣接する倒伏ガイド２１の間に案内された圃場の穀稈は、株元ガイド４８の左右両端部（前側固定部５１及び後側固定部５２を含む）によって左右内側を支点として株元側を押さえられながら、支点の上方且つ株元の左右外側を屈曲部５３によって左右一方側に向けて徐々に押出されるように構成されている。このため、倒伏ガイド２１は、穀稈の株元側を左右一方側に折曲げて穀稈を倒伏させることができる（図７参照）。 That is, according to the lodging guide 21 having the above-described configuration, the grain culms in the field guided between the adjacent lodging guides 21 have the left and right end portions (front side fixing portion 51 and rear side fixing portion 52) of the stock root guide 48. The left and right inner sides are used as fulcrums to hold down the stock root side, and the upper left and right sides of the stock root are gradually extruded by the bending portion 53 toward the left and right sides. Therefore, the lodging guide 21 can bend the stock root side of the grain culm to the left or right side to lie down the culm (see FIG. 7).

このとき、倒伏ガイド２１によって左右方向一方側に倒伏される穀稈は、必ず刈取部３の左右方向中心側に向かつて倒伏されるため、穀稈が刈取部３の左右外側方向に倒伏されて刈取部３側から圃場に零れ落ちる事態を確実に防止できる。 At this time, the grain culm that is laid down on one side in the left-right direction by the lodging guide 21 is always laid down toward the center side in the left-right direction of the cutting portion 3, so that the culm is laid down in the left-right outer direction of the cutting portion 3. It is possible to reliably prevent the situation where the cutting section 3 side spills into the field.

上述の構成によれば、圃場の穀稈は、倒伏ガイド２１によって左右方向一方側に倒伏された状態で刈取られることにより、掻込オーガ１４側に供給される刈取穀稈が必ず左右方向に傾いた状態となる。 According to the above configuration, the grain culms in the field are cut in a state of being laid down on one side in the left-right direction by the lodging guide 21, so that the cut culms supplied to the scraping auger 14 side are always tilted in the left-right direction. It becomes a state.

これにより、例えば、刈取対象がトウモロコシ等のように比較的長手状で折れ難く（又は擦り難く）且つ枝葉等が少ない穀稈の場合、該刈取穀稈が、掻込オーガ１４の搬送棒１９の移動方向に対して略平行となるように真後ろに寄りかかるように倒れると、搬送棒１９等への引っ掛かりが少なくなって刈取穀稈が十分に掻込めない虞があるところ、本実施形態では、刈取穀稈が左右方向に傾けられるため、搬送棒１９等が刈取穀稈に引っ掛かり易くなる。 As a result, for example, when the cutting target is a grain culm that is relatively long, hard to break (or hard to rub), and has few branches and leaves, such as corn, the cut grain culm is the transport rod 19 of the scraping auger 14. If the culm is tilted so as to lean directly behind so as to be substantially parallel to the moving direction, the catch on the transport rod 19 or the like may be reduced and the culm may not be sufficiently scratched. Since the grain culm is tilted in the left-right direction, the transport rod 19 and the like are easily caught on the cut grain culm.

［倒伏部材の固定構造］
つぎに、本発明の要部である倒伏部材４３の固定構造について、図６及び図７を参照して説明する。 [Fixed structure of lodging member]
Next, the fixed structure of the lodging member 43, which is a main part of the present invention, will be described with reference to FIGS. 6 and 7.

倒伏部材４３は、取付孔４３ａ、４３ｂ、４３ｃが形成される固定部５４を有し、該固定部５４がガイド部材４２に対してボルト固定される。このとき、倒伏部材４３は、ガイド部材４２の穀稈案内位置Ｇよりも内側でガイド部材４２に固定される。例えば、図７の（ａ）に示す第１実施形態では、外側面部がガイド部材４２の穀稈案内位置Ｇとなる前側固定部５１及び後側固定部５２の内側面部に倒伏部材４３の固定部５４をボルト固定している。 The lodging member 43 has a fixing portion 54 in which mounting holes 43a, 43b, and 43c are formed, and the fixing portion 54 is bolted to the guide member 42. At this time, the lodging member 43 is fixed to the guide member 42 inside the grain culm guide position G of the guide member 42. For example, in the first embodiment shown in FIG. 7A, the fixing portion of the lodging member 43 is attached to the inner side surface portion of the front side fixing portion 51 and the rear side fixing portion 52 in which the outer surface portion is the grain guide position G of the guide member 42. 54 is bolted.

このような倒伏部材４３の固定構造によれば、倒伏部材４３の固定部５４（特に前端部）に穀稈の一部が引っ掛かって堆積することを防止できるので、該堆積による穀稈の詰まりや、倒伏ガイド２１の破損を回避できる。具体的に説明すると、例えば、前側固定部５１及び後側固定部５２の外側面部に倒伏部材４３の固定部５４をボルト固定した場合、倒伏部材４３の固定部５４の前端部と前側固定部５１との間の隙間に穀稈の一部（例えば、表皮の繊維など）が入り込み、それを起点として屑が堆積して穀稈の詰まりが発生したり、堆積した屑の押圧力によって倒伏部材４３の固定部５４と前側固定部５１との間の隙間が押し広げられ、倒伏ガイド２１が破損する虞があるが、本実施形態の倒伏ガイド２１によれば、このような問題を解決することが可能になる。また、倒伏部材４３の固定部５４と穀稈との間には、ガイド部材４２の左右側部から上方に立ち上がる前側固定部５１及び後側固定部５２が介在するので、倒伏部材４３の固定部に対する穀稈の接触をより確実に防止できる。 According to such a fixing structure of the lodging member 43, it is possible to prevent a part of the grain culm from being caught and accumulated on the fixing portion 54 (particularly the front end portion) of the lodging member 43, so that the grain culm is clogged due to the accumulation. , It is possible to avoid damage to the lodging guide 21. Specifically, for example, when the fixing portion 54 of the lodging member 43 is bolted to the outer surface portions of the front fixing portion 51 and the rear fixing portion 52, the front end portion and the front fixing portion 51 of the fixing portion 54 of the lodging member 43 are fixed. A part of the grain culm (for example, fibers of the epidermis) enters the gap between the culm and the culm is clogged due to the accumulation of debris from that point, or the lodging member 43 due to the pressing force of the accumulated debris. The gap between the fixing portion 54 and the front fixing portion 51 may be widened and the lodging guide 21 may be damaged. However, according to the lodging guide 21 of the present embodiment, such a problem can be solved. It will be possible. Further, since the front fixing portion 51 and the rear fixing portion 52 rising upward from the left and right side portions of the guide member 42 are interposed between the fixing portion 54 of the lodging member 43 and the grain culm, the fixing portion of the lodging member 43 is provided. The contact of the culm with the culm can be prevented more reliably.

［第１実施形態の効果］
叙述の如く構成された本実施形態によれば、走行機体２と、走行機体２の前部に昇降可能に連結され、穀稈を刈り取って後方に搬送する刈取装置３と、走行機体２に設けられ、刈取部３が刈り取った穀稈を脱穀処理する脱穀装置４と、を備える汎用コンバインＣであって、刈取部３は、穀稈を後方に掻き込むリール１３と、穀稈を刈り取る刈刃１６Ａと、刈り取った穀稈を掻き込むオーガ１４と、刈刃１６Ａの前側に配置され、穀稈を左右方向に倒伏させる倒伏ガイド２１と、を備えるので、オーガ１４による掻き込みを円滑にして穀稈の詰まりを抑制できる。 [Effect of the first embodiment]

It is a general-purpose combine C including a grain removal device 4 for removing the grain culms cut by the cutting unit 3, and the cutting unit 3 has a reel 13 for scraping the grain culms rearward and a cutting blade for cutting the grain culms. Since it is provided with 16A, an auger 14 for scraping the cut grain culm, and a lodging guide 21 arranged in front of the cutting blade 16A to lay down the grain culm in the left-right direction, the grain can be smoothly scraped by the auger 14. Clogged culm can be suppressed.

また、倒伏ガイド２１は、刈刃１６Ａから前方に延出し、かつ左右方向に並ぶ複数のガイド部材４２と、隣接するガイド部材４２間に導入される穀稈に干渉し、該穀稈を左右方向に倒伏させる倒伏部材４３と、を備え、倒伏部材４３は、ガイド部材４２の穀稈案内位置Ｇよりも内側でガイド部材４２に固定されるので、倒伏部材４３の固定部５４に穀稈の一部が引っ掛かって堆積することを防止し、該堆積による穀稈の詰まりや、倒伏ガイド２１の破損を回避できる。 Further, the lodging guide 21 interferes with the plurality of guide members 42 extending forward from the cutting blade 16A and arranged in the left-right direction and the grain culm introduced between the adjacent guide members 42, and causes the grain culm in the left-right direction. Since the lodging member 43 is fixed to the guide member 42 inside the grain culm guide position G of the guide member 42, the culm member 43 is fixed to the fixing portion 54 of the culm member 43. It is possible to prevent the portion from being caught and accumulating, and to avoid clogging of the culm due to the accumulation and damage to the lodging guide 21.

また、ガイド部材４２は、左右側部から上方に立ち上がり、その外側面部が前記穀稈案内位置Ｇとなる前側固定部５１及び後側固定部５２を有し、倒伏部材４３は、前側固定部５１及び後側固定部５２の内側面部に固定される固定部５４を有するので、倒伏部材４３の固定部５４に対する穀稈の接触を確実に防止できる。 Further, the guide member 42 has a front fixing portion 51 and a rear fixing portion 52 whose outer surface portion rises upward from the left and right side portions and whose outer surface portion is the grain culm guide position G, and the lodging member 43 has a front fixing portion 51. Since it has a fixing portion 54 fixed to the inner side surface portion of the rear fixing portion 52, it is possible to reliably prevent the grain culm from coming into contact with the fixing portion 54 of the lodging member 43.
