As shown also in the upper right side of the stir-up star wheel (A) pivoted on the rightmost side (the left / right judgment in this specification is based on the state seen in the forward direction of the vehicle body; the same applies hereinafter) Conveying chain (B) wound around is composed of a single part from the start position of the cereal squeeze position to the rear end (passing position to the handling depth adjustment chain (C)). The angle (α) formed between the scraping path (B1) and the subsequent conveying path (B2) is increased, and the necessary angle is required unless the bent portion is pressed from the outside (conveying path side of the cereal) and bent. The structure cannot be secured.

このような従来の1本チェンの構成では、前記掻込み経路(B1)は、掻込み作用を優先して前後方向に近い角度に配置すると穀稈の掻込み作用を確実に行うことができても、後続する搬送径路(B2)が前後方向に配置されて前後長さが長くなり、大型となって、他の搬送チェン(D)との合流が円滑にできなくなる課題が残る。   In such a conventional one-chain structure, if the scraping path (B1) is arranged at an angle close to the front-rear direction giving priority to the scraping action, the trapping action of the cereal can be reliably performed. However, the subsequent conveyance path (B2) is arranged in the front-rear direction, the front-rear length becomes long, the size becomes large, and there remains a problem that it is not possible to smoothly merge with another conveyance chain (D).

それに対して、本件出願の発明は、図3に示すように、刈取般送装置の最も右側に配置する掻込みスターホイル(A)の上方から穀稈掻込み方向に向けて短い株元掻込みチェン(3a)を設け、該株元掻込みチェン(3a)から刈取穀稈を受継ぐ別の株元搬送チェン(3b)を設けた2本チェンの構成にしている。したがって、本件出願の発明は、前側の株元掻込みチェン(3a)を掻込み作用に最も適する角度に装置することが可能であり、後続の株元搬送チェン(3b)も隣接する他の合流搬送チェン(7)との関係を配慮して、搬送穀稈の合流に適する角度に配置することができる。   On the other hand, as shown in FIG. 3, the invention of the present application is a short stock rake from the upper side of the rake star wheel (A) arranged on the rightmost side of the cutting and general feeding device toward the culm creaking direction. A chain (3a) is provided, and a two-chain structure is provided in which another stock transport chain (3b) that inherits the harvested cereal rice bran from the stock stock scooping chain (3a). Therefore, the invention of the present application makes it possible to set the front stock former take-up chain (3a) at an angle most suitable for the take-up action, and the subsequent stock run-up chain (3b) is also connected to other adjacent confluences. In consideration of the relationship with the conveyance chain (7), it can be arranged at an angle suitable for the merging of the conveyance kernels.

要するに、本件出願の発明は、株元掻込みチェン(3a)と株元搬送チェン(3b)とを、図3に示すように、それぞれ単独の2本チェン構成にしているから、両者の間に形成される角度(β)も自由に決められて前側の掻込みチェン(3a)と、後続する搬送チェン(3b)とがそれぞれ充分に機能が発揮できる角度に設定することができて、前述した従来装置の課題を解消することができるものとすることを目的としている。   In short, the invention of the present application has the stock former scooping chain (3a) and the stock transporting chain (3b) as shown in FIG. The angle (β) to be formed is also freely determined and can be set to an angle at which the front scraping chain (3a) and the succeeding transfer chain (3b) can sufficiently function, respectively, as described above. The object is to solve the problems of the conventional apparatus.

Next, an embodiment of the cereal takeover transfer device 30 will be described.
First, as shown in FIG. 1 and FIG. 5, the cereal takeover transfer device 30 is located at the end position of the cereal conveyance path of the chopping conveyance device 4, and conveys the cereal to the feed chain 15 of the threshing device 12. It is configured to smoothly pass on and supply. As shown in FIGS. 6 and 7, the takeover chain 31 of the device 30 is wound around a drive sprocket 32 and two idle rollers 33, 33 each pivoted on a corner portion, It is configured to rotate along the arcuate chain rail 34 arranged on the back side while sliding. And as shown in the drawing, the upper and lower derailment prevention plates 35 and 36 are provided on the upper side and the lower side along the movement path (position of the chain rail 34) of the takeover chain 31 to prevent derailment of the takeover chain 31. It is configured. In this case, the upper and lower derailment prevention plates 35 and 36 are portions that are conveyed while sequentially changing to a lying state in order to supply the conveyed cereals to the threshing device 12, so that the overhang to the conveying passage is shortened above. The bottom is made longer.

そして、穂先側案内カバー37は、図8、及び図9に示すように、その下縁を前記した上側脱線防止板35のすぐ上面に隙間がないように接近して円弧形状に添わせて設けた構成としている。   As shown in FIGS. 8 and 9, the tip side guide cover 37 is provided so that its lower edge is close to the upper surface of the above-described upper derailment prevention plate 35 so that there is no gap and is attached to the arc shape. It has a configuration.

そして、株元ガイド杆38は、図面に示すように、基部を前記下側脱線防止板36に溶接して固着し、中間部位から先端側を搬送通路の株元搬送側へ折り曲げて突出させ、上面側で搬送穀稈の株元部分を上方で外側方向にガイドして、脱穀装置12のフィードチェン15の上側に受継ぎ易いように案内する構成としている。   Then, as shown in the drawing, the stock guide guide rod 38 is welded and fixed to the lower derailment prevention plate 36, and the tip side is bent from the intermediate portion to the stock transport side of the transport path to protrude, It is set as the structure which guides the stock base part of a conveyance cereal to the upper direction on the upper surface side so that it may be easily inherited to the upper side of the feed chain 15 of the threshing device 12.

以上述べたように、まず、前記チェンレール34は、他の部材(脱線防止板35,36等)から独立した単体の構成としており、単独で着脱ができるために、加工(焼入れ作業等)やメンテナンス等が容易となり、焼入れ等で耐久性を向上できる利点がある。そして、前記穂先側案内カバー37は、上側脱線防止板35のすぐ上面に下縁を隙間がないように接近して設けているから、藁屑や脱粒した籾の溜まり場なくなった利点がある。   As described above, first, the chain rail 34 is configured as a single unit independent of other members (derailment prevention plates 35, 36, etc.), and can be detached and attached independently. There are advantages that maintenance and the like are facilitated and durability can be improved by quenching or the like. Since the tip side guide cover 37 is provided with a lower edge close to the upper surface of the upper derailment prevention plate 35 so as not to have a gap, there is an advantage that there is no accumulation of waste dust or shed grains.

そして、株元ガイド杆38は、搬送穀稈の株元をフィードチェン15を跨がすように向こう側に案内して受継ぎを良好にしながら、別体の取付部材を必要とせず、取付の簡略化を図り、引継ぎチェン31の脱線防止にも役立つ特徴がある。   Then, the stock guide guide rod 38 guides the stock source of the transported grain straw to the other side so as to straddle the feed chain 15 to improve the inheritance, and does not require a separate mounting member. There is a feature that simplifies and helps prevent derailment of the takeover chain 31.

つぎに、扱深さ調節チェン5の実施例を説明する。
まず、扱深さ調節チェン5は、図1に基づいて説明したが、株元搬送チェン3bの終端部から受継いだ穀稈を、図外の扱深調節制御装置の制御作動によって稈身方向に移動調節しながら扱深さを適正位置に調節して脱穀装置12に供給する装置である。そして、扱深さ調節チェン5は、図10に示すように、機体側支持部41に調節自由に軸受けした駆動スプロケット42と、終端側の遊動ローラ43とに巻き掛けた構成としているが、この場合、支持フレーム40と補強連結取付部材48とによって駆動スプロケット42側と、遊動ローラ43側とを連結して一体に枠組みした構成としている。
Next, an embodiment of the handling depth adjustment chain 5 will be described.
First, the handling depth adjustment chain 5 has been described with reference to FIG. It is an apparatus which adjusts the handling depth to an appropriate position while adjusting the movement to supply to the threshing apparatus 12. Further, as shown in FIG. 10, the handling depth adjustment chain 5 is configured to be wound around a drive sprocket 42 that is freely supported by the machine body side support portion 41 and an idler roller 43 on the end side. In this case, the driving sprocket 42 side and the idler roller 43 side are connected to each other by the support frame 40 and the reinforcing connecting attachment member 48 so as to form an integral framework.

そして、Uパイプ44は、図10、及び図15に示すように、一方の端部を上記補強連結取付部材48(支持フレーム40側)に連結し、他方を挟持杆45側の連結部材46に連結して穀稈通路を迂回させた状態にしてチェン5側と挟持杆45側とを一体に連結してU字空間部分に穀稈を通過させる構成としている。   As shown in FIGS. 10 and 15, the U pipe 44 has one end connected to the reinforcing connection mounting member 48 (support frame 40 side) and the other connected to the connection member 46 on the holding rod 45 side. The chain 5 side and the sandwiching basket 45 side are connected together by connecting and bypassing the grain straw passage so that the grain flour passes through the U-shaped space.

そして、扱深さ調節チェン5は、支持フレーム40の中間部位に制御連動杆47が設けられ、図外の制御モータに接続して制御作動される構成になっているが、実施例の場合、搬送上手側の駆動スプロケット42側を回動支点として、遊動ローラ43側を作動して、穀稈の稈身方向に制御調節する構成としている。   And the handling depth adjustment chain 5 is configured to be controlled by being connected to a control motor (not shown) provided with a control interlocking rod 47 at an intermediate portion of the support frame 40. With the driving sprocket 42 side on the upper side of the conveyance as a rotation fulcrum, the idler roller 43 side is actuated to control and adjust in the slimming direction of the grains.

そして、支持フレーム40と補強取付部材48とは、一体として扱深さ調節チェン5の主要な構成部材となるが、図11から図14に示す各断面は、それぞれ該当する断面を示し、それぞれL型(図11参照)、箱型(図12、乃至図14参照)に形成し、特に、前記制御連動杆47の取付位置より遊動ローラ43側を箱型に形成してフレームの強度アップを図る構成としている。   The support frame 40 and the reinforcing mounting member 48 are integrated as main components of the handling depth adjusting chain 5, but the cross sections shown in FIGS. 11 (see FIG. 11) and box shape (see FIGS. 12 to 14), and in particular, the floating roller 43 side is formed in a box shape from the mounting position of the control interlocking rod 47 to increase the strength of the frame. It is configured.

このように、扱深さ調節チェン5は、主要な構成部材となる支持フレーム40と補強取付部材48との剛性を高めることによって、調節制御時に発生していたフレームのねじれ等をなくして確実な作動ができるものとなった。従来装置では、支持フレームが捻じれてUパイプが変位し、挟持杆45がチェンの中心位置から離れた位置を押圧して、チェン5が脱線する弊害が発生することがあったが、それらの課題が解消できた。   As described above, the handling depth adjustment chain 5 can reliably remove the torsion of the frame that has occurred during the adjustment control by increasing the rigidity of the support frame 40 and the reinforcing mounting member 48 that are main components. It became possible to operate. In the conventional apparatus, the support frame is twisted and the U-pipe is displaced, and the clamping rod 45 presses a position away from the center position of the chain. The problem was solved.

つぎに、スクレーパ50は、図18、及び図19に示すように、前記駆動スプロケット42への藁屑等の巻き付きを防止するように設けるが、従来装置は、図16、及び図17に示すように、支持フレーム51と一体にして取り付ける構成をとっていた。それに対して、実施例は、図18、及び図19に示すように、支持フレーム51に着脱自在にねじ締めして取り付ける構成にした。したがって、実施例のスクレーパ50は、支持フレームに関係なく単体で着脱することができ駆動スプロケット42の交換等も楽にできる特徴がある。   Next, as shown in FIGS. 18 and 19, the scraper 50 is provided so as to prevent winding of the sawdust and the like around the drive sprocket 42, but the conventional apparatus is as shown in FIGS. 16 and 17. In addition, it is configured to be attached integrally with the support frame 51. On the other hand, in the embodiment, as shown in FIGS. 18 and 19, the support frame 51 is detachably screwed and attached. Therefore, the scraper 50 of the embodiment has a feature that it can be detached and attached independently of the support frame, and that the drive sprocket 42 can be easily replaced.

つぎに、扱深さ調節チェン5の搬送終端部に軸架している遊動ローラ43のテンション装置53について実施例を説明する。
まず、この発明の実施例に係るテンション装置53は、従来装置(図20参照)の欠陥を解消して、図21、及び図22に示すように、チェンの伸び量をアジャスト側の目視で確認できる構成とし、更に、それの調整位置も目で見ながら、調整作業が容易にできる構成としている。
Next, an embodiment of the tension device 53 of the idler roller 43 that is pivoted on the conveyance end portion of the handling depth adjusting chain 5 will be described.
First, the tension device 53 according to the embodiment of the present invention eliminates the defects of the conventional device (see FIG. 20) and visually confirms the amount of chain extension on the adjust side as shown in FIGS. Further, the adjustment work can be easily performed while visually checking the adjustment position.

従来の構成は、図19に示すように、短く形成したスペーサ54を保持パイプ55の中に挿入した構成であったから、右側への移動を外部から確認できず、チェン56が緩んで伸びても保持パイプ55の端部から外に出ることがない構成であった。したがって、従来のテンション装置53は、チェン56が緩んできても簡単に確認ができないために、穀稈の搬送障害がでて初めて気づく場合が多く、チェン56の張力の調整をする場合もアジャストボルト57の調節量が解らず、感と経験で行っていた。   As shown in FIG. 19, the conventional configuration is a configuration in which a spacer 54 formed short is inserted into the holding pipe 55, so that the rightward movement cannot be confirmed from the outside, and the chain 56 is loosened and extended. The configuration was such that the end of the holding pipe 55 did not go outside. Therefore, since the conventional tension device 53 cannot be easily confirmed even if the chain 56 is loosened, it is often noticed only after the trouble of conveying the cereal, and the adjustment bolt is also used when adjusting the tension of the chain 56. I couldn't understand the adjustment amount of 57, and it was done with feeling and experience.

それに対して、本案の実施例に係るテンション装置53は、図21、及び図22に示すように、スペーサ54を従来より長く形成して、扱深さ調節チェン5を長時間使用してチェン56が伸びて遊動ローラ43がスプリング58の張圧力に押されて移動すると、一体構成の保持パイプ55が遊動ローラ43と共にチェン56側に移動するから、スペーサ54が、逆に保持パイプ55の端部から外に出てくることになる。   On the other hand, as shown in FIGS. 21 and 22, the tension device 53 according to the embodiment of the present proposal has a spacer 54 formed longer than the conventional one and the handling depth adjusting chain 5 is used for a long time. When the idle roller 43 is pushed and moved by the tension pressure of the spring 58, the integral holding pipe 55 moves to the chain 56 side together with the idle roller 43, so that the spacer 54 is conversely the end of the holding pipe 55. Will come out from.

したがって、オペレータは、そのスペーサ54の突出長さを目視して、チェン56の緩み量(伸び量)が解り、調整量(アジャストすべき長さ)を知ることができる。そして、実施例の場合、チェン56の調整量は、図21に示すように、保持パイプ55の端部に、スペーサ54の端部を合わせた位置が適正な調整(後)位置であり、チェン張力の調整位置が目で確認できる実用的効果がある。   Therefore, the operator can visually recognize the protruding length of the spacer 54, understand the loosening amount (elongation amount) of the chain 56, and know the adjustment amount (the length to be adjusted). In the case of the embodiment, as shown in FIG. 21, the adjustment amount of the chain 56 is an appropriate adjustment (rear) position where the end of the spacer 54 is aligned with the end of the holding pipe 55. There is a practical effect in which the tension adjustment position can be visually confirmed.

以上述べたように、実施例の扱深さ調節チェン5のテンション装置53は、チェン56の伸び量も、それの調整量(アジャストボルト57を調整する位置)も目視で確認できる優れた特徴がある。   As described above, the tension device 53 of the working depth adjustment chain 5 of the embodiment has an excellent feature that the extension amount of the chain 56 and the adjustment amount (position for adjusting the adjustment bolt 57) can be visually confirmed. is there.

つぎに、穀稈引起し装置60の前側に設けたサブデバイダ61について、実施例を説明する。
実施例に係るサブデバイダ61は、図23に示すように、下部を分草杆62の中央位置か、又はこれを貫通して裏側機枠に取り付け、上部を穀稈引起し装置60の上部外側に取り付けて順次上部を前方側に膨出状に突出させ、縦方向に高い位置まで分草作用ができる構成としている。そして、案内プレート63は、図24、及び図25に示すように、上記サブデバイダ61と穀稈引起し装置60の前板60aとの間を塞ぐように配置して取り付け、圃場の穀稈を上下に渡って板面で案内できる構成としている。なお、図24は平らな板面で案内し、図25は案内面を湾曲状に形成して脱粒を低減しながらスムースに案内するものとしている。
Next, an embodiment of the sub divider 61 provided on the front side of the grain raising device 60 will be described.
As shown in FIG. 23, the sub-divider 61 according to the embodiment is attached to the rear machine frame at the lower portion at the center position of the weed cocoon 62, and the upper portion is raised outside the upper portion of the device 60. The upper part protrudes in a bulging shape to the front side in order, and it is set as the structure which can perform a weeding action to a high position in the vertical direction. 24 and 25, the guide plate 63 is disposed and attached so as to close the space between the sub-divider 61 and the front plate 60a of the grain raising device 60, and the rice grains in the field are moved up and down. The structure is such that it can be guided on the plate surface. 24 is guided by a flat plate surface, and in FIG. 25, the guide surface is formed in a curved shape and smoothly guided while reducing degranulation.

なお、サブデバイダ61は、図26に示すように、その下部を分草杆62の後ろ側を通して分草支持杆64に取り付ける構成にしても良く、又、図27に示すように、穀稈引起し装置60の前板60aの下部に取り付ける構成でも良い。   In addition, as shown in FIG. 26, the sub-divider 61 may be configured to be attached to the weed support rod 64 through the rear side of the weed rod 62, as shown in FIG. The structure attached to the lower part of the front board 60a of the apparatus 60 may be sufficient.

このように構成すると、分草杆62は、サブデバイダ61の取り付けに関係なくなり、自由に位置調節ができる。
そして、サブデバイダ61は、図28に示すように、上端部を枢着Pとして下部を左右に揺動させて位置調節ができる構成にする事も自由であるが、この場合、案内プレート63の取付部(前板60a)に横向きの長孔を設けて、同方向に一体に調節可能にすればよい。
With this configuration, the weed ridge 62 is not related to the attachment of the sub divider 61 and can be freely adjusted in position.
As shown in FIG. 28, the sub-divider 61 can freely be adjusted in position by pivoting the lower portion to the left and right with the upper end portion pivoted P. In this case, the guide plate 63 is attached. It suffices to provide a laterally elongated hole in the portion (front plate 60a) so that it can be adjusted integrally in the same direction.

以上述べたように、実施例のサブデバイダ61は、案内プレート63を設けた点に特徴があり、運転操縦席から稈身方向の分草状態の確認がし易く、又案内プレート63のために穀稈がサブデバイダ61を構成する杆に絡み付くことがない利点がある。更に、案内プレート63は、図25に示すように、穀稈案内面を湾曲形状にすると、既に述べたように、脱粒を低減しながらスムースに案内することができる特徴がある。   As described above, the sub-divider 61 of the embodiment is characterized in that the guide plate 63 is provided, and it is easy to check the weeding state in the slimming direction from the driver's cockpit. There is an advantage that the bag does not get entangled with the bag forming the sub divider 61. Furthermore, as shown in FIG. 25, the guide plate 63 has a feature that, when the culm guide surface has a curved shape, it can be smoothly guided while reducing degranulation as described above.

つぎに、掻込みスターホイル2の巻付防止手段について、実施例を説明する。
既に、図1に基づいて説明しが、刈取搬送装置4は、前部低位置の穀稈掻込み条列ごとに掻込みスターホイル2を軸架して穀稈の掻込み作用を行う構成としているが、掻込みスターホイルは、常に、掻込み穀稈の巻き付きが発生し、その対策が課題となっている。
Next, examples of the winding preventing means for the stir-up star wheel 2 will be described.
Although already explained based on FIG. 1, the reaping and conveying device 4 is configured to perform the scumming action of the culm by pivoting the stirrer starwheel 2 for each front low position of the culm scoring row. However, raked starfoil has always been entangled with chopped cereals, and countermeasures for it have been an issue.

従来から、掻込みスターホイルは、例えば、平5−25445号特許公報や特開平9−65750号公開特許公報に見られるように、掻込みスターホイルと巻付防止杆に関する技術が提案され、又、昭58−29226号公開実用新案公報に示されているように、回転体に巻きついた藁等を除去するスクレーパの技術が公開されている。   Conventionally, for example, as shown in Japanese Patent Laid-Open No. 5-25445 and Japanese Patent Laid-Open No. 9-65750, a technology related to a hardened starfoil and an anti-winding rod has been proposed. As shown in Japanese Utility Model Publication No. 58-29226, a scraper technique for removing wrinkles around a rotating body is disclosed.

まず、巻付防止杆65は、図30に示すように、掻込みスターホイル66の中心部分に設けている円筒体67からできる限り遠い位置で、しかも、その円筒体67の外周に沿って等間隔に隔てた位置に設けることが巻付を防止できる構成である。従来の巻付防止杆65は、図29に示すように、円筒体67との間隔が狭いために巻き付きが起きる原因となっていた。   First, as shown in FIG. 30, the winding prevention hook 65 is located as far as possible from the cylindrical body 67 provided in the central portion of the stir-up star wheel 66, and along the outer periphery of the cylindrical body 67. It is the structure which can prevent winding by providing in the position separated from the space | interval. As shown in FIG. 29, the conventional anti-winding rod 65 is a cause of winding due to a narrow distance from the cylindrical body 67.

このように、掻込みスターホイル66は、図30に示すように構成すると、図29の構成に比較して大幅に巻き付きが防止できる。
つぎに、スクレーパ68は、図31に示すように、掻込みスターホイル66の中心寄りの上面と円筒体67の周面とにスクレーパ作用ができるように接近して設けた構成としている。このように構成すると、スクレーパ68は、スターホイル66の上面と円筒体67の下部周面との両面に同時にスクレーパ作用をして巻きついた藁屑等を取り除くことができる。
As described above, when the stir-up star wheel 66 is configured as shown in FIG. 30, it is possible to prevent the winding star foil 66 from being greatly wound as compared with the configuration of FIG.
Next, as shown in FIG. 31, the scraper 68 is configured to be provided close to the upper surface near the center of the stir-up star wheel 66 and the peripheral surface of the cylindrical body 67 so as to be able to act as a scraper. If comprised in this way, the scraper 68 can remove the scrap etc. which wound by carrying out a scraper action simultaneously on both surfaces of the upper surface of the star wheel 66, and the lower peripheral surface of the cylindrical body 67. FIG.

つぎに、図32、及び図33に示した実施例は、通常の巻付防止杆65の上側に穀稈ガイド杆69を配置して、上下二重の構成にして巻付き作用を防止する構成をとっている。
そして、図34と図35とに示す実施例は、上記巻付防止杆65をピアノ線に置き換えて構成したものである。
Next, in the embodiment shown in FIG. 32 and FIG. 33, the culm guide rod 69 is arranged on the upper side of the normal wrapping prevention rod 65 so as to prevent the wrapping action with a double upper and lower configuration. Have taken.
The embodiment shown in FIG. 34 and FIG. 35 is configured by replacing the wrapping prevention rod 65 with a piano wire.

以上、掻込みスターホイル66の上側周辺に配置する巻付防止杆65の各実施例を列挙したが、いずれも巻付き防止機能に加えて、メンテナンス性がよく破損や変形に対応できる特徴がある。   As mentioned above, although each Example of the anti-winding hook 65 arrange | positioned around the upper side of the stirring star wheel 66 was enumerated, all have the characteristic that it is easy to maintain and can respond to breakage and a deformation | transformation in addition to the anti-winding function. .

つぎに、運転操縦座席の右側(オペレータの乗降側)に設けたウインカー70とバックミラー71との取付け構成について実施例を説明する。
まず、ウインカー70は、図36、及び図37に示すように、ハンドル(側部の乗降時に握る把持部を含む)72と一体にした取付け用ステー73に取り付けて構成している。更に、バックミラー71は、図面に示すように、上記取付け用ステー73に取付具74を介して取付けてこれらを一体構成としている。
Next, an embodiment will be described with respect to a mounting structure of the winker 70 and the rearview mirror 71 provided on the right side of the driver's control seat (operator getting on / off side).
First, as shown in FIGS. 36 and 37, the winker 70 is configured to be attached to a mounting stay 73 integrated with a handle 72 (including a grip portion to be gripped when the side portion gets on and off). Further, as shown in the drawing, the rearview mirror 71 is attached to the mounting stay 73 via a mounting tool 74 to form an integral structure.

そして、ウインカー70とウインカー71とは、図36の正面視で解るように、いずれも機体の右外側に位置し、それぞれの機能が発揮できるように後方に障害物が突出しないように開放した構成としている。   Then, as shown in the front view of FIG. 36, the winker 70 and the winker 71 are both located on the right outer side of the aircraft, and are opened so that no obstacles protrude rearward so that the respective functions can be performed. It is said.

そして、バックミラー71は、図37に示すように、側面視で乗降時の通路から前側に退避した位置にあり、邪魔にならず、しかも、下側に横軸に支架して前後方向に操作する駐車ブレーキレバー75の回動操作範囲の上側に位置する構成としている。   As shown in FIG. 37, the rearview mirror 71 is in a position retracted to the front side from the passage when getting on and off in a side view, and does not get in the way, and is supported on the horizontal axis on the lower side and operated in the front-rear direction. The parking brake lever 75 is configured to be located above the rotation operation range.

以上、述べたように、実施例の構成は、バックミラー71とウインカー70とが本来の機能を充分に発揮できる位置に設けられ、しかも、運転操縦席への乗降時に支障とならず、駐車ブレーキレバー75の操作にも支障がない特徴がある。   As described above, the configuration of the embodiment is provided at a position where the rearview mirror 71 and the blinker 70 can sufficiently perform their original functions, and does not interfere with getting on and off the driver's cockpit. There is a feature that the operation of the lever 75 is not hindered.

つぎに、コンバインの後部に取付けたバランスウエイト77について実施例を説明する。
実施例のバランスウエイト77は、水を入れるタンク78からなり、コンバインカッター79の後部カバーに代えて取り付けた構成としている。そして、バランスウエイト77は、実施例の場合、図39に示すように、横長のタンク78を上下方向に複数段を重ねて着脱自由に取付けて一体構成とし、各タンク78ごとにそれぞれ給水口80と排水口81とを設けた構成としている。
Next, an embodiment of the balance weight 77 attached to the rear part of the combine will be described.
The balance weight 77 of the embodiment is composed of a tank 78 for containing water, and is attached in place of the rear cover of the combine cutter 79. In the embodiment, as shown in FIG. 39, the balance weight 77 has a horizontally long tank 78 that is stacked in a plurality of stages in the vertical direction and is detachably attached to form an integral structure. And a drain outlet 81 are provided.

そして、バランスウエイト77は、各タンク78を着脱自由に構成しているから、ウエイト調節が自由に出来る。
以上説明したように、実施例に係るバランスウエイト77は、コンバインカッター79の後部カバーを兼ねており、低コストで製作ができる。更に、実施例の場合、水を横長のタンク78に給水し、これを着脱自由に重ねる構成であるから、ウエイト調節が可能であると共に、ウエイトが水であるにもかかわらず、車体が左右に傾斜しても横移動がほとんどなく、ウエイトの横移動が防止できる利点がある。
Since the balance weight 77 is configured so that each tank 78 can be freely attached and detached, the weight can be adjusted freely.
As described above, the balance weight 77 according to the embodiment also serves as the rear cover of the combine cutter 79 and can be manufactured at low cost.
