前記公知例のうち前者は、ナローガイドを調節軸で張出量を調節する構成のため、操縦部からの操作は困難であり、調節が面倒であるという課題がある。
即ち、ナローガイドの調節は、一度すればよいものではなく、圃場内を周回しながら作業するコンバインでは、走行方向によって、穀稈の倒伏方向が相違し、その都度ナローガイドの張出量を変更することで、未刈り穀稈の踏み倒しを防止するのである。
Among the known examples, the former has a problem that the operation from the control unit is difficult and adjustment is troublesome because the narrow guide is adjusted by the adjustment shaft to adjust the protruding amount.
In other words, the narrow guide adjustment is not a one-time adjustment. In a combine that works while circling in the field, the overhanging direction of the cereals differs depending on the traveling direction, and the amount of narrow guide overhang changes each time. By doing so, it is possible to prevent the uncut cereals from being stepped over.

この点、前記公知例のうち前者は、モータにより遠隔操作可能にしているが、藁屑や塵埃や泥土といった汚染物質が多くあるナローガイド近傍にモータを設けているので、故障や耐久性が低いという課題がある。   In this regard, the former of the above-mentioned known examples can be remotely operated by a motor, but since the motor is provided in the vicinity of the narrow guide where there are many contaminants such as sawdust, dust and mud, failure and durability are low.

That is, when a load is applied to push the narrow guide (20) toward the machine body frame (1), the front end of the front narrow guide (21) and the rear end of the rear narrow guide (22) move back and forth, and instantly. The load can be released to prevent breakage. In addition, the rear portion of the narrow guide (22) is attached to the fuselage frame (1) to increase the overall length of the narrow guide (20). And the narrow guide (20) can be absorbed, and the narrow guide (20) can be prevented from being damaged or deformed.
According to the second aspect of the invention, in addition to the effect of the first aspect of the invention, the amount of extension of the narrow guide (20) can be adjusted from the control unit (7) according to the state of the field, And workability can be improved.

本発明の実施例を図により説明すると、1は機体フレーム、2は該機体フレーム1の下方位置に設けた走行装置、3は機体フレーム1の上方位置に設けた脱穀装置、4は脱穀装置3の前側に設けた刈取部、5はグレンタンク、6はグレンタンク5内の穀粒を排出する排出オーガ、7は操縦部である。   An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a machine frame, 2 denotes a traveling device provided at a lower position of the machine frame 1, 3 denotes a threshing device provided at an upper position of the machine frame 1, and 4 denotes a threshing device 3. The cutting part provided in the front side, 5 is a glen tank, 6 is a discharge auger for discharging the grains in the glen tank 5, and 7 is a control part.

前記刈取部4は、最先端位置に分草装置8を左右に並設し、各分草装置8の後側に分草装置8が分草した穀稈を引起す引起装置9を設け、引起装置9の後側には刈刃10を設け、刈刃10の上方から後側には刈刃10によって刈り取った穀稈を搬送する穀稈搬送装置11を設ける。   The mowing unit 4 has a weeding device 8 arranged side by side at the most advanced position, and a pulling device 9 that raises the cereals weeded by the weeding device 8 on the rear side of each weeding device 8. A cutting blade 10 is provided on the rear side of the device 9, and a culm transporting device 11 that transports the culm cut by the cutting blade 10 from above the cutting blade 10 is provided.

穀稈搬送装置11の構成は任意であり、図6中、12は穀稈搬送装置11の一部を構成する掻き込み装置、13は穀稈を後方に搬送する後側搬送装置、14は扱深さ調節装置を兼用する株元搬送装置、15は刈取フレーム、16は支持フレーム、17は支持台である。   The configuration of the cereal conveying device 11 is arbitrary. In FIG. 6, 12 is a scraping device that constitutes a part of the cereal conveying device 11, 13 is a rear conveying device that conveys the cereals backward, and 14 is a handling device. A stock transporter that also serves as a depth adjusting device, 15 is a cutting frame, 16 is a support frame, and 17 is a support base.

穀稈搬送装置11(後側搬送装置13)の終端は、脱穀装置3に穀稈を供給する穀稈供給搬送装置19の始端部に臨ませる。後側搬送装置13および株元搬送装置14は、刈取部4の後側で操縦部7の側方に位置させている。   The terminal end of the cereal conveyance device 11 (rear conveyance device 13) faces the start end of the cereal supply and conveyance device 19 that supplies the threshing device 3 with the cereal. The rear transport device 13 and the stock transport device 14 are positioned to the side of the control unit 7 on the rear side of the cutting unit 4.

しかして、刈取部4の前記分草装置8の側方から脱穀装置3の後部側方にかけて未刈り穀稈を分草するナローガイド(未刈り穀稈分草装置)20を設ける。ナローガイド20は、軸棒部材により形成し、前側ナローガイド21と後側ナローガイド22とに分割して形成する(図2)。前側ナローガイド21の前端部は前記分草装置8を取付けた分草フレーム23に回動自在に取付け、前側ナローガイド21の後端と後側ナローガイド22の前端とを軸24により屈曲自在に取付け、この軸24の部分がナローガイド20の前後中間に設けた屈曲部Kとなる。後側ナローガイド22の後端は前記機体フレーム1の任意の固定部に前後移動自在に取付ける。   Thus, a narrow guide (uncut grain stalk weeding device) 20 is provided for weeding uncut cereals from the side of the weeding device 8 of the cutting unit 4 to the rear side of the threshing device 3. The narrow guide 20 is formed by a shaft rod member, and is divided into a front narrow guide 21 and a rear narrow guide 22 (FIG. 2). A front end portion of the front narrow guide 21 is rotatably attached to a weeding frame 23 to which the weeding device 8 is attached, and a rear end of the front narrow guide 21 and a front end of the rear narrow guide 22 are bent by a shaft 24. The portion of the shaft 24 is attached to be a bent portion K provided in the front and rear middle of the narrow guide 20. The rear end of the rear narrow guide 22 is attached to an arbitrary fixed portion of the body frame 1 so as to be movable back and forth.

前記ナローガイド20の前後中間部(屈曲部K)には操作伝達手段25の一端を取付け、分草フレーム23の他端は前記操縦部7に設けたナローガイド操作部材(操作レバー)26に接続する。   One end of an operation transmission means 25 is attached to the front and rear intermediate portion (bending portion K) of the narrow guide 20, and the other end of the weeding frame 23 is connected to a narrow guide operation member (operation lever) 26 provided in the operation portion 7. To do.

したがって、操縦部7からナローガイド20の張出と格納の操作ができ、操作性を向上させることができる。
操作伝達手段25は、前記ナローガイド操作部材26に取付けた操作リンク27、および、該操作リンク27と前記ナローガイド20とを連結する連結杆28、並びに、該連結杆28の移動方向を案内するガイド29により構成する。
Therefore, the narrow guide 20 can be extended and retracted from the control unit 7 and the operability can be improved.
The operation transmitting means 25 guides the operating link 27 attached to the narrow guide operating member 26, the connecting rod 28 connecting the operating link 27 and the narrow guide 20, and the moving direction of the connecting rod 28. A guide 29 is used.

操作リンク27の下部は連結杆28に軸30により回動自在に取付ける。
連結杆28は断面四角筒形状に形成し、同様に、断面四角筒形状に形成したガイド29に摺動のみ自在に挿通する。ガイド29には操作リンク27と連結杆28との軸着部である軸30の取付部分が移動する移動溝31を形成する。ガイド29は、前記機体フレーム1の前側横枠(前側の横枠)32に固定状態に取付ける。
The lower portion of the operation link 27 is attached to the connecting rod 28 by a shaft 30 so as to be rotatable.
The connecting rod 28 is formed in a square tube shape in cross section, and similarly, is slidably inserted through a guide 29 formed in a square tube shape in cross section. The guide 29 is provided with a moving groove 31 in which a mounting portion of the shaft 30 that is a shaft attachment portion between the operation link 27 and the connecting rod 28 moves. The guide 29 is fixedly attached to the front side horizontal frame (front side horizontal frame) 32 of the machine body frame 1.

33はナローガイド操作部材26の移動を案内するガイドである。
操作伝達手段25は、ナローガイド操作部材26を下方に押すと、操作リンク27が連結杆28を外側に移動させ、ナローガイド20を張り出させる。反対に、ナローガイド操作部材26を上方に牽引すると、操作リンク27は連結杆28を内側に移動させてナローガイド20を格納する。
Reference numeral 33 denotes a guide for guiding the movement of the narrow guide operating member 26.
When the operation transmitting means 25 pushes the narrow guide operating member 26 downward, the operation link 27 moves the connecting rod 28 outward and causes the narrow guide 20 to project. On the contrary, when the narrow guide operation member 26 is pulled upward, the operation link 27 moves the connecting rod 28 inward to store the narrow guide 20.

そのため、ナローガイド操作部材26の位置によりナローガイド20の張出量(代)が調節可能となる。
また、操作伝達手段25によりナローガイド20を出入りさせるので、操作力を軽減させることができる。
For this reason, the amount of protrusion (allowance) of the narrow guide 20 can be adjusted by the position of the narrow guide operating member 26.
Moreover, since the narrow guide 20 is moved in and out by the operation transmission means 25, the operation force can be reduced.

また、ナローガイド操作部材26の高さ位置によって、ナローガイド20の張出代を調節でき、操作性を向上させる。
しかして、前記操作伝達手段25の操作リンク27と連結杆28とガイド29は、平面視において、横一線状態に配置すると(図2、図6)、操作伝達力を一層軽減でき、好適である。
Further, the overhang allowance of the narrow guide 20 can be adjusted according to the height position of the narrow guide operating member 26, and the operability is improved.
Therefore, if the operation link 27, the connecting rod 28, and the guide 29 of the operation transmission means 25 are arranged in a horizontal line state in plan view (FIGS. 2 and 6), the operation transmission force can be further reduced, which is preferable. .

即ち、ナローガイド20の屈曲部K(軸24)と操作伝達手段25のナローガイド操作部材26の前後位置を同じにすることで、操作伝達手段25の操作リンク27と連結杆28とを横一列に配置でき、操作伝達手段25の操作性を向上させる。   That is, by making the bent portion K (shaft 24) of the narrow guide 20 and the narrow guide operating member 26 of the operation transmitting means 25 the same in the front-rear position, the operation link 27 and the connecting rod 28 of the operation transmitting means 25 are aligned horizontally. The operability of the operation transmission means 25 is improved.

また、ナローガイド操作部材26は操縦部7の固定部に上下するように設け、連結杆28は前側横枠32に設けたガイド29内を移動するだけであるから、操作リンク27および連結杆28の作動スペースを小さくでき、機体全体の小型化に貢献できる。   In addition, the narrow guide operation member 26 is provided so as to move up and down on the fixed portion of the control unit 7, and the connection rod 28 only moves within the guide 29 provided on the front lateral frame 32. The operating space can be reduced, contributing to the miniaturization of the entire aircraft.

この場合、操作リンク27と連結杆28とガイド29は、穀稈供給搬送装置19が脱穀装置3の脱穀室(図示省略)への穀稈供給を円滑にするために、脱穀装置3の前側に設けた入口ジョーゴ34の下方に位置させると、空間を有効利用できて、好適である。   In this case, the operation link 27, the connecting basket 28, and the guide 29 are provided on the front side of the threshing device 3 in order for the mash supply and transfer device 19 to smoothly supply the mash to the threshing chamber (not shown) of the threshing device 3. If it is located below the provided entrance jaw 34, the space can be used effectively, which is preferable.

しかして、図7以下は、ナローガイド20の他の実施例を示し、前記前側ナローガイド21の前端の前側取付部35を、前記分草フレーム23に設けた前側案内部材36に移動および回動自在に取付ける。   FIG. 7 and subsequent figures show another embodiment of the narrow guide 20, and the front attachment portion 35 at the front end of the front narrow guide 21 is moved and rotated to the front guide member 36 provided on the weed frame 23. Install freely.

したがって、ナローガイド20が張出・格納で出入りするときに、前側ナローガイド21の前端を前後移動させるので、ナローガイド20が出入りが円滑になる。
ナローガイド20は、後側ナローガイド22の前側部分に支持アーム38の先端を軸(第1軸)39により回動自在に取付け、支持アーム38の基部は前記前側横枠32に設けた取付部材40に軸(第2軸)41により回動自在に取付ける。支持アーム38には常時支持アーム38をナローガイド20の格納方向に付勢するバネ42を取付ける。
Therefore, when the narrow guide 20 moves in and out by overhanging and retracting, the front end of the front narrow guide 21 is moved back and forth, so that the narrow guide 20 is smoothly moved in and out.
The narrow guide 20 is attached to the front portion of the rear narrow guide 22 so that the tip of the support arm 38 can be rotated by a shaft (first shaft) 39, and the base of the support arm 38 is an attachment member provided on the front lateral frame 32. A shaft (second shaft) 41 is rotatably attached to 40. A spring 42 that urges the support arm 38 in the retracting direction of the narrow guide 20 is attached to the support arm 38 at all times.

前記軸41または支持アーム38には操作伝達手段25の一端を取付け、操作伝達手段25の他端は前記操縦部7に設けたナローガイド操作部材(操作レバー)26に連結する。実施例では、操作伝達手段25をワイヤーケーブル43により構成し、ワイヤーケーブル43は操縦部7に設けたナローガイド操作部材26に接続している。   One end of the operation transmission means 25 is attached to the shaft 41 or the support arm 38, and the other end of the operation transmission means 25 is connected to a narrow guide operation member (operation lever) 26 provided in the control unit 7. In the embodiment, the operation transmission means 25 is constituted by a wire cable 43, and the wire cable 43 is connected to a narrow guide operation member 26 provided in the control unit 7.

44はワイヤーケーブル43を接続したアームである(図8等の一部の図において、理解を容易にするため、ワイヤーケーブル43の先端とアーム44とを接続していない)。
後側ナローガイド22の後部の後側取付部45は、機体フレーム1に設けた後側案内部材46に移動自在に取付ける。
Reference numeral 44 denotes an arm to which the wire cable 43 is connected (in some drawings such as FIG. 8, the tip of the wire cable 43 and the arm 44 are not connected for easy understanding).
The rear attachment portion 45 of the rear portion of the rear narrow guide 22 is movably attached to a rear guide member 46 provided on the body frame 1.

したがって、ナローガイド20の張出・格納させる張出・格納機構を、支持アーム38により構成したリンク機構で構成し、ナローガイド20の屈曲部Kを支持アーム38の先端に形成しているから、ナローガイド20を機体フレーム1側に押す荷重が掛かると、前側ナローガイド21の前端および後側ナローガイド22の後端が夫々前後に移動して、瞬時に荷重を逃がし、破損防止する。   Therefore, the extension / retraction mechanism for extending / retracting the narrow guide 20 is constituted by a link mechanism constituted by the support arm 38, and the bent portion K of the narrow guide 20 is formed at the tip of the support arm 38. When a load that pushes the narrow guide 20 toward the machine body frame 1 is applied, the front end of the front narrow guide 21 and the rear end of the rear narrow guide 22 move forward and backward, respectively, thereby releasing the load instantaneously and preventing damage.

即ち、ナローガイド20が張出位置と格納位置に移動すると、張出位置ではナローガイド20の全長が短く、格納位置では全長が長くなり、このナローガイド20の全長の変化を、前側ナローガイド21の前端および後側ナローガイド22の後端との前後二か所に振り分けて吸収するので、吸収が円滑且つ迅速にできるのである。   That is, when the narrow guide 20 is moved to the extended position and the retracted position, the entire length of the narrow guide 20 is short at the extended position, and the full length is long at the retracted position. Since it is distributed and absorbed in two places, front and rear, and the rear end of the rear narrow guide 22, the absorption can be performed smoothly and quickly.

そのため、ナローガイド20は荷重(衝撃)に対する変形が少なく、張出・格納の際の所謂「コゼ」による負荷も小さい。
前記刈取部4の前側案内部材36および機体フレーム1の後側案内部材46は、夫々軸棒部材により形成し、前側ナローガイド21および後側ナローガイド22の前側取付部35および後側取付部45はリング形状に形成し、夫々の接触面積を小さくしてナローガイド20が円滑に移動するようにすると共に、前側取付部35および後側取付部45は前側案内部材36および後側案内部材46の軸方向以外の方向にも回動し、ナローガイド20に機体フレーム1側に押す荷重が掛かったときに変形して荷重を逃がし、破損防止する。
Therefore, the narrow guide 20 is less deformed with respect to the load (impact), and the load caused by the so-called “kose” at the time of extension / storage is also small.
The front guide member 36 of the cutting part 4 and the rear guide member 46 of the machine body frame 1 are formed by shaft rod members, respectively, and the front attachment part 35 and the rear attachment part 45 of the front narrow guide 21 and the rear narrow guide 22 are formed. Is formed in a ring shape so that the narrow guide 20 can be moved smoothly by reducing the respective contact areas, and the front mounting portion 35 and the rear mounting portion 45 are formed by the front guide member 36 and the rear guide member 46, respectively. It also rotates in directions other than the axial direction, and when the load that pushes the narrow guide 20 toward the machine body frame 1 is applied, it deforms to release the load and prevent breakage.

しかして、前記ナローガイド操作部材26は、操縦部7のナローガイド操作部50に設けた操作溝51に係合させてワイヤーケーブル43を操縦部7側に牽引するが(図11では、理解を容易にするため、ナローガイド操作部50の側面図および正面図も同一図面に図示している)、前記操作溝51の内の張出位置のとき係合する張出操作溝51Aは、ナローガイド20に格納方向に大きな衝撃(荷重)が掛かると、張出操作溝51Aからナローガイド操作部材26が外れるように構成する(図15)。   Thus, the narrow guide operation member 26 is engaged with the operation groove 51 provided in the narrow guide operation unit 50 of the control unit 7 to pull the wire cable 43 toward the control unit 7 (see FIG. 11 for understanding). For the sake of simplicity, a side view and a front view of the narrow guide operating portion 50 are also shown in the same drawing), and the overhanging operation groove 51A to be engaged at the overhanging position in the operation groove 51 is a narrow guide. When a large impact (load) is applied to 20 in the retracting direction, the narrow guide operation member 26 is configured to be detached from the overhang operation groove 51A (FIG. 15).

そのため、通常は、ナローガイド操作部材26によるワイヤーケーブル43の牽引操作でナローガイド20は張り出しているが、大きな衝撃(荷重)が掛かると、張出操作溝51Aからナローガイド操作部材26が外れ、ナローガイド20はバネ42の弾力により格納方向に移動し、破損・変形を防止する。   Therefore, normally, the narrow guide 20 is projected by the pulling operation of the wire cable 43 by the narrow guide operating member 26. However, when a large impact (load) is applied, the narrow guide operating member 26 is detached from the projecting operation groove 51A. The narrow guide 20 is moved in the retracted direction by the elasticity of the spring 42 to prevent damage or deformation.

また、前記ナローガイド操作部50には、操作溝51を複数形成し、ナローガイド20の張出量を段階的に操作するように構成すると、圃場の状態に応じてナローガイド20の張出量を調節できて、好適である。   Further, when the narrow guide operation portion 50 is formed with a plurality of operation grooves 51 and the projecting amount of the narrow guide 20 is operated stepwise, the projecting amount of the narrow guide 20 according to the state of the field. Can be adjusted, which is preferable.

実施例では、「収納」、「短稈」、「標準」の三段の操作溝51を形成している(図13、図15)。
しかして、前記前側ナローガイド21の後端と後側ナローガイド22の前端との屈曲部Kは、屈曲部K中心に前側ナローガイド21の前端が上下しうるように構成し、前側案内部材36に移動自在に取付けた前側ナローガイド21の前側取付部35が、刈取部4の上下に際して、前側案内部材36を移動するように構成する(図17)。
In the embodiment, three-stage operation grooves 51 of “storage”, “tank”, and “standard” are formed (FIGS. 13 and 15).
Thus, the bent portion K between the rear end of the front narrow guide 21 and the front end of the rear narrow guide 22 is configured so that the front end of the front narrow guide 21 can move up and down around the bent portion K, and the front guide member 36 is arranged. The front mounting portion 35 of the front narrow guide 21 movably mounted on the front side is configured to move the front guide member 36 when the cutting unit 4 is moved up and down (FIG. 17).

即ち、刈取部4の回動中心(上下回動中心)Sとナローガイド20の前側ナローガイド21の回動中心となる屈曲部Kとの位置が前後にずれているので、刈取部4が上下回動すると、刈取部4の前側案内部材36と前側ナローガイド21の前側取付部35との位置関係が変化するが、刈取部4の前側案内部材36と前側ナローガイド21の前側取付部35とが相対的に移動することにより、刈取部4とナローガイド20との位置ずれを吸収する。 That is, since the position of the rotation center (vertical rotation center) S of the cutting part 4 and the bent part K that becomes the rotation center of the front narrow guide 21 of the narrow guide 20 is shifted back and forth, the cutting part 4 moves up and down. When rotating, the positional relationship between the front guide member 36 of the cutting part 4 and the front mounting part 35 of the front narrow guide 21 changes, but the front guide member 36 of the cutting part 4 and the front mounting part 35 of the front narrow guide 21 By moving relatively, the position shift between the cutting unit 4 and the narrow guide 20 is absorbed.

したがって、後側ナローガイド22の後部を機体フレーム1に取付けて全体長を長くしたナローガイド20でありながら、刈取部4の上下回動に伴う刈取部4とナローガイド20との位置ずれを吸収できナローガイド20の破損・変形を防止する。 Accordingly, the rear guide 22 is attached to the fuselage frame 1 and the overall length of the narrow guide 20 is increased. However, the misalignment between the cutting portion 4 and the narrow guide 20 due to the vertical rotation of the cutting portion 4 is absorbed. can, to prevent damage or deformation of the narrow guide 20.

また、機体フレーム1と刈取部4との位置関係が相違する他の機種であっても、刈取部4に前側案内部材36を設けることにより、ナローガイド20の取付が可能となり、汎用性を向上させられる。   In addition, even in other models in which the positional relationship between the machine body frame 1 and the cutting unit 4 is different, the narrow guide 20 can be attached by providing the front guide member 36 in the cutting unit 4, and versatility is improved. Be made.

また、ナローガイド20は、後側ナローガイド22に軸着した支持アーム38に常時ナローガイド20を格納方向に付勢するバネ42を設けているから、ナローガイド操作部材26を張出操作すると、ワイヤーケーブル43が牽引され、ワイヤーケーブル43は支持アーム38をナローガイド20の張出方向に回動させ、支持アーム38の先端側が後側ナローガイド22の前部および前側ナローガイド21の後部を外側移動させ、ナローガイド20を張出す。   Further, since the narrow guide 20 is provided with a spring 42 that constantly urges the narrow guide 20 in the retracted direction on the support arm 38 that is pivotally attached to the rear narrow guide 22, when the narrow guide operating member 26 is extended, The wire cable 43 is pulled, and the wire cable 43 rotates the support arm 38 in the protruding direction of the narrow guide 20, and the front end side of the support arm 38 outwards the front part of the rear narrow guide 22 and the rear part of the front narrow guide 21. Move and narrow guide 20 is extended.

反対に、ナローガイド操作部材26を格納操作すると、ワイヤーケーブル43を弛めるので、ワイヤーケーブル43はバネ42の弾力を作用させて支持アーム38をナローガイド20の格納方向に回動させて格納する。   On the other hand, when the narrow guide operating member 26 is retracted, the wire cable 43 is loosened. Therefore, the wire cable 43 causes the spring 42 to act to rotate the support arm 38 in the retracting direction of the narrow guide 20 for storage.

したがって、操縦部7からの遠隔操作によりナローガイド20の張出・格納させられる。
また、支持アーム38の回動によりナローガイド20の張出・格納を行うので、操作の「コゼ」による負荷が小さく、操作性を向上させる。
Accordingly, the narrow guide 20 is extended and stored by remote control from the control unit 7.
In addition, since the narrow guide 20 is extended and retracted by the rotation of the support arm 38, the load caused by the operation “knitting” is small and the operability is improved.

しかして、刈取部4の前側案内部材36および機体フレーム1の後側案内部材46は何れも軸棒部材により構成し、前側取付部35と後側取付部45は、前側案内部材36と後側案内部材46にスライド自在に取付けているから、ナローガイド20の全長の変化量の吸収を円滑でき、また、他の機種にもそのまま代用可能となり、汎用性を向上させられる(図18、図20)。   Thus, both the front guide member 36 of the cutting unit 4 and the rear guide member 46 of the machine body frame 1 are constituted by shaft rod members, and the front mounting part 35 and the rear mounting part 45 are composed of the front guide member 36 and the rear side. Since the guide member 46 is slidably attached to the guide member 46, the amount of change in the entire length of the narrow guide 20 can be absorbed smoothly, and can be substituted for other models as it is, thereby improving versatility (FIGS. 18 and 20). ).

しかして、分草装置8は所定の左右幅を有して形成し、刈取部4の固定部に基部を固定した分草フレーム23の先端に取付け、分草フレーム23は刈取部4の前側案内部材36が分草装置8の未刈り地側の外側縁より内側(既刈り地側)に位置するように構成する(図21)。   Thus, the weeding device 8 is formed to have a predetermined left and right width, and is attached to the tip of the weeding frame 23 whose base is fixed to the fixed part of the cutting part 4, and the weeding frame 23 is guided to the front side of the cutting part 4. The member 36 is configured so as to be positioned on the inner side (the already cut ground side) than the outer edge on the uncut ground side of the weeding device 8 (FIG. 21).

即ち、ナローガイド20の前側取付部35を分草装置8の裏(影)に位置(隠して)させて、未刈り地側の未刈り穀稈との接触抵抗が増加するのを防止する。
この点、ナローガイド20の張出機構構成を、前側ナローガイド21の前側を直線的にスライド移動させる構成により実現しているので、合理的な構成となる。
That is, the front attachment portion 35 of the narrow guide 20 is positioned (hidden) behind the weeding device 8 to prevent an increase in contact resistance with the uncut grain culm on the uncut ground side.
In this respect, the configuration of the overhang mechanism of the narrow guide 20 is realized by a configuration in which the front side of the front narrow guide 21 is slid linearly, so that a rational configuration is obtained.

しかして、取付部材40は、その基部を前後方向の横軸58により前側横枠32に回動自在に取付け、横軸58には常時支持アーム38を横軸58中心に下方回動方向に付勢するバネ59を取付ける(図22、図23)。支持アーム38には別途上下用ワイヤーケーブル60の一端を取付け、上下用ワイヤーケーブル60は操縦部7に別途設けた上下操作用の上下操作レバー61に接続する。   Thus, the mounting member 40 has its base portion rotatably attached to the front lateral frame 32 by the front-rear horizontal shaft 58, and the horizontal support shaft 38 is always attached to the horizontal shaft 58 in the downward rotational direction around the horizontal shaft 58. A spring 59 is attached (FIGS. 22 and 23). One end of an up / down wire cable 60 is separately attached to the support arm 38, and the up / down wire cable 60 is connected to an up / down operation lever 61 for up / down operation provided separately in the control unit 7.

したがって、上下操作レバー61により上下用ワイヤーケーブル60を牽引すると、支持アーム38が上方回動し、張り出したナローガイド20の位置を高くし、未刈り穀稈の上側部分まで機体から離すように案内し、特に、穀稈供給搬送装置19の始端部付近で穀稈供給搬送装置19による未刈り穀稈の巻き込みを防止できて、好適である。   Therefore, when the vertical wire cable 60 is pulled by the vertical operation lever 61, the support arm 38 is rotated upward, the position of the overhanging narrow guide 20 is increased, and the upper portion of the uncut grain cedar is guided away from the airframe. In particular, it is possible to prevent the culm supply / conveyance device 19 from entraining uncut cereals near the starting end of the cereal supply / conveyance device 19.

即ち、ナローガイド20を上下させる取付部材40で支持アーム38を支持し、バネ59と上下用ワイヤーケーブル60により上下操作するので、部品点数を削減でき、好適である。   That is, the support arm 38 is supported by the mounting member 40 that moves the narrow guide 20 up and down, and is moved up and down by the spring 59 and the up and down wire cable 60, which is preferable because the number of parts can be reduced.

しかして、前記ワイヤーケーブル43およびバネ42と、上下用ワイヤーケーブル60およびバネ59は、脱穀装置3の前側に設けた入口ジョーゴ34の下方に位置させると、空間を有効利用できて、好適である(図24、図6)。   Therefore, if the wire cable 43 and the spring 42, and the up and down wire cable 60 and the spring 59 are positioned below the inlet jawo 34 provided on the front side of the threshing device 3, the space can be used effectively, which is preferable. (FIGS. 24 and 6).

また、ワイヤーケーブル43およびバネ42と、上下用ワイヤーケーブル60およびバネ59上に藁屑が溜るのを防止でき、また、これらの設置および調節作業を容易に行える。   Further, accumulation of sawdust on the wire cable 43 and the spring 42 and the upper and lower wire cables 60 and the spring 59 can be prevented, and the installation and adjustment work can be easily performed.
