Reference numerals 56 and 57 denote guide members provided at the ends of the clamping rods 52 and 53, respectively, which are elastically urged so as to approach the transport chain 54 and the transport chain 55 side.

　しかして、図４に示したように、５条刈の刈取部５に設けた前記支持フレーム４５には、前記右株元側集束搬送装置２０ｂおよび後株元側集束搬送装置２４の挾扼杆５８と、前記中間株元側集束搬送装置２０ｃの挾扼杆５９を取付ける。支持フレーム４５の後側下部４８の左右側には、ハの字形状であって、かつ、前記後側下部４８と平行となるように突出させたステー６０を固定し、該ステー６０の右側には前記挾扼杆５８を、ステー６０の左側には挾扼杆５９の終端を、それぞれ前記搬送チエン５４および搬送チエン５５のそれぞれに対して遠近自在となるように出入自在に取付けている。また、前記挾扼杆５８の始端部は自由端であるが、前記挾扼杆５９の始端部は前記分草杆１４に取付けている。 Thus, as shown in FIG. 4, the support frame 45 provided in the cutting section 5 of the five-row cutting is provided with a clamping rod of the right stock base side conveyer 20b and the rear stock base conveyer 24. 58 and a clamping rod 59 of the intermediate stock source side conveyer 20c. On the left and right sides of the rear lower portion 48 of the support frame 45, a stay 60 having a U-shape and projecting so as to be parallel to the rear lower portion 48 is fixed. Is mounted on the left side of the stay 60 so that the end of the clamping rod 59 can be freely moved in and out of the transport chain 54 and the transport chain 55, respectively. The starting end of the clamping rod 58 is a free end, but the starting end of the clamping rod 59 is attached to the weeding rod 14.

　しかして、前記各引起装置１６は、前記刈取部５側に固定の後側ケース６１と該後側ケース６１に着脱自在に取付けられる前側カバー６２とに分割可能に形成した引起ケース６３内に、引起ラグ６４を所定間隔を置いて起伏自在に取付けた無端チエン６５の駆動機構を設けて構成される。６６は駆動歯車、６７はテンション歯車、６８は前記後側ケース６１内の下部に設けたボスであり、該ボス６８に下部案内ローラー６９を回転のみ自在に嵌合させ、前記駆動歯車６６とテンション歯車６７と下部案内ローラー６９とに前記無端チエン６５を掛け回す。 Thus, each of the raising devices 16 has a raising case 63 formed so as to be splittable into a rear case 61 fixed to the cutting section 5 side and a front cover 62 detachably attached to the rear case 61. A drive mechanism for an endless chain 65 having raised lugs 64 mounted at predetermined intervals so as to be able to move up and down is provided. 66 is a driving gear, 67 is a tension gear, and 68 is a boss provided at a lower portion in the rear case 61. A lower guide roller 69 is fitted to the boss 68 only in a freely rotatable manner. The endless chain 65 is wound around the gear 67 and the lower guide roller 69.

　正面からみて、前記引起ケース６３の一側は前記引起ラグ６４が起立状態で上昇する作用側に形成し、前記引起ケース６３の他側は前記引起ラグ６４が倒伏状態で下降する非作用側となるが、作用側の後側ケース６１と前側カバー６２との間には前記引起ラグ６４を起立状態に案内するラグガイド７０を設ける。前記ラグガイド７０は、前板７１と後板７２と作用側の側板７３とにより断面形状が略チャンネル形状であって、前記引起ラグ６４の移動方向に長く形成し、前記側板７３には非作用側に凹こむ前記無端チエン６５の通路７４を形成する。７５は前記前板７１と後板７２に形成した前後に貫通する挿入孔、７６は前記後側ケース６１に設けた前記前側カバー６２側に突出する複数の突起であり、一部の突起７６の前端部（先端部）には係合溝７７を形成する。前記前側カバー６２の内側には係合板７８を固定し、係合板７８には前記突起７６の係合溝７７が係合する係合部７９を形成する。即ち、ラグガイド７０は、その挿入孔７５を前記突起７６に嵌合させ、この状態で後側ケース６１の突起７６の係合溝７７に前側カバー６２の係合板７８の係合部７９を係合させて取付け固定する。 As viewed from the front, one side of the raising case 63 is formed on an operating side where the raising lug 64 rises in the upright state, and the other side of the raising case 63 is formed as a non-operating side on which the raising lug 64 lowers in the down state. However, a lug guide 70 for guiding the raising lug 64 in an upright state is provided between the rear case 61 and the front cover 62 on the working side. The lug guide 70 has a substantially channel-shaped cross-section formed by the front plate 71, the rear plate 72, and the side plate 73 on the operation side, and is formed to be long in the moving direction of the raising lug 64, and does not act on the side plate 73. A passage 74 of the endless chain 65 that is recessed to the side is formed. Reference numeral 75 denotes an insertion hole formed in the front plate 71 and the rear plate 72 that penetrates back and forth. Reference numeral 76 denotes a plurality of protrusions provided on the rear case 61 and protruding toward the front cover 62. An engagement groove 77 is formed at the front end (tip). An engagement plate 78 is fixed inside the front cover 62, and an engagement portion 79 is formed on the engagement plate 78 to be engaged with the engagement groove 77 of the projection 76. That is, the lug guide 70 engages the insertion hole 75 with the projection 76, and in this state, engages the engagement portion 79 of the engagement plate 78 of the front cover 62 with the engagement groove 77 of the projection 76 of the rear case 61. Attach and fix.

　しかして、前記ラグガイド７０の前記前板７１と前記後板７２には、係合溝８０をそれぞれ形成し、係合溝８０には円形の弾性部材８１を嵌合させる。弾性部材８１は前記係合溝８０より前後側に突出し、後側ケース６１と前側カバー６２とのがた付きを防止している。８２は前記前側カバー６２の上部を前記下向き伝動筒２５側に固定する係合体であり、弾性を有する線杆より下向きコの次形状に形成され、前記下向き伝動筒２５に設けた係合片８３に下側から挿入係合される。即ち、引起ケース６３は、後側ケース６１の上部を前記下向き伝動筒２５に固定し、後側ケース６１の下部を前記分草杆１４に固定し、後側ケース６１に前側カバー６２を取付けるが、前記係合体８２は係合片８３に弾着してがた付きを防止する。 Thus, an engagement groove 80 is formed in each of the front plate 71 and the rear plate 72 of the lug guide 70, and a circular elastic member 81 is fitted into the engagement groove 80. The elastic member 81 protrudes forward and backward from the engagement groove 80 to prevent rattling between the rear case 61 and the front cover 62. Reference numeral 82 denotes an engagement body that fixes the upper portion of the front cover 62 to the downward transmission cylinder 25 side, and is formed in a shape following the lower side of the elastic rod and has an engagement piece 83 provided on the downward transmission cylinder 25. Is inserted and engaged from below. That is, the raising case 63 fixes the upper part of the rear case 61 to the downward transmission cylinder 25, fixes the lower part of the rear case 61 to the weeding rod 14, and attaches the front cover 62 to the rear case 61. The engaging body 82 is elastically attached to the engaging piece 83 to prevent rattling.

　また、前記下部案内ローラー６９の後側に位置する後側ケース６１の後面には、下部案内ローラー６９のボス６８の溝８４に係合する係合フック８５を設ける。８６は係合フック８５を付勢するバネ、８７は係合フック８５を開かせるツマミである。 Further, an engagement hook 85 is provided on the rear surface of the rear case 61 located on the rear side of the lower guide roller 69 so as to engage with the groove 84 of the boss 68 of the lower guide roller 69. 86 is a spring for urging the engagement hook 85, and 87 is a knob for opening the engagement hook 85.

　図１９は、前記刈取部５の左側（未刈地側）に設けたナローガイド８８の取付構造を示し、ナローガイド８８の前端は前記引起ケース６３下部後側の分草杆１４に回転自在に軸着し、ナローガイド８８は後側に至るに従い外側でかつ上側に位置する形状に形成され、ナローガイド８８の中間部には回動アーム８９の上端を固定し、回動アーム８９の下端は前記分草杆１４の後端部に設けたステー９０に軸着する。したがって、ナローガイド８８の前端を前記引起ケース６３下部後側の分草杆１４に回転自在に軸着しているので、穀稈の搬送通路に干渉せず、円滑に作用し、穀稈屑等の異物の付着も防止できる。また、ナローガイド８８の中間部を回動アーム８９により支持しているので、ナローガイド８８の剛性も向上させる。また、前記ステー９０は前記分草杆１４と刈刃フレーム１３とに固定しているので、強度メンバーの一部を構成する。なお、ナローガイド８８は不使用時には刈取部５側に回動させて収納する。 FIG. 19 shows a mounting structure of a narrow guide 88 provided on the left side (uncut ground side) of the cutting section 5, and the front end of the narrow guide 88 is rotatable with the weeding rod 14 at the lower rear of the raising case 63. The narrow guide 88 is formed so as to be positioned outward and upward as it reaches the rear side, and the upper end of the rotating arm 89 is fixed to an intermediate portion of the narrow guide 88, and the lower end of the rotating arm 89 is The weeding rod 14 is attached to a stay 90 provided at the rear end of the weeding rod 14. Therefore, since the front end of the narrow guide 88 is rotatably mounted on the weeding rod 14 at the lower rear side of the raising case 63, the narrow guide 88 does not interfere with the conveying path of the grain stalk, and acts smoothly, and the grain scum etc. Foreign matter can be prevented from adhering. Further, since the intermediate portion of the narrow guide 88 is supported by the rotating arm 89, the rigidity of the narrow guide 88 is also improved. Further, since the stay 90 is fixed to the weeding rod 14 and the cutting blade frame 13, it constitutes a part of the strength member. When the narrow guide 88 is not used, it is rotated toward the reaping unit 5 and stored.

　次に作用を述べる。前記の構成であるから、機体を前進走行させると、各分草体１５により分草し、分草された穀稈は引起装置１６により引起され、引起された穀稈は刈刃１９により切断され、ラグ式穂先掻込装置１７および株元掻込スターホイル装置１８により後方に掻込まれ、左右株元側集束搬送装置２０ａ、２０ｂにより株元が挾持され、穂先側搬送装置２１により穂先側が搬送されて搬送通路を通って一箇所の引継点Ａに搬送されて株元引継搬送装置２２及び穂先引継搬送装置２３に引継がれ、該株元引継搬送装置２２及び穂先引継搬送装置２３により脱穀室の側部の穀稈供給装置に引継がれ、該穀稈供給装置により脱穀室に供給されて脱穀される。また、５条刈の場合は、左右中間株元側集束搬送装置２０ａ、２０ｂ、２０ｃにより株元が挾持され、穂先側搬送装置２１により穂先側が搬送され、右株元側集束搬送装置２０ｂと中間株元側集束搬送装置２０ｃにより搬送された穀稈は、後株元側集束搬送装置２４により一箇所の引継点Ａに搬送されて株元引継搬送装置２２及び穂先引継搬送装置２３に引継がれ、該株元引継搬送装置２２及び穂先引継搬送装置２３により脱穀室の側部の穀稈供給装置に引継がれ、該穀稈供給装置により脱穀室に供給されて脱穀される。 Next, the operation will be described. With the above-described configuration, when the aircraft is driven to travel forward, weeding is performed by each weeding body 15, the weeded culm is raised by the raising device 16, and the raised cereal culm is cut by the cutting blade 19, It is scraped backward by the lug-type tip scraping device 17 and the stock-raising star wheel device 18, the stock is clamped by the right and left stock-source focusing and conveying devices 20 a and 20 b, and the tip side is transported by the tip-side transporting device 21. Is transferred to one takeover point A through the transfer passage and is taken over by the stock takeover transfer device 22 and the head takeover transfer device 23, and the side of the threshing room is controlled by the stock takeover transfer device 22 and the tip takeover transfer device 23. Is transferred to the grain stalk supply device, and supplied to the threshing room by the grain stalk supply device for threshing. In the case of five-row cutting, the stocks are clamped by the left and right intermediate stock base side conveyers 20a, 20b and 20c, the head side is conveyed by the head side conveyer 21, and the right stock base side conveyer 20b The grain culm conveyed by the stock side concentrating and conveying device 20c is conveyed to one takeover point A by the rear stock side concentrating and conveying device 24, and is handed over to the stock source handing over conveying device 22 and the tip handing over conveying device 23, The stock is transferred to the grain culm supply device on the side of the threshing room by the stock transfer system 22 and the head transfer device 23, and supplied to the threshing room by the cereal culm supply device for threshing.

　この場合、４条刈では、左右株元側集束搬送装置２０ａ、２０ｂは、搬送チエン搬送チエン５４、５５と該搬送チエン５４、５５の側部近傍に設けた前記挾扼杆５２、５３により穀稈の根部を挾持搬送するが、前記挾扼杆５２、５３は、支持フレーム３７に設けたステー５１に前記搬送チエン５４および搬送チエン５５のそれぞれに対して遠近自在となるように出入自在に取付けられ、前記ステー５１は下部３８に対して略水平方向に突出するように形成しているから、挾扼杆５２、５３の下方位置に空間を形成して穀稈を円滑に搬送する。 In this case, in the four-row cutting, the right and left stock former side conveyer devices 20a, 20b are fed by the transport chain transport chains 54, 55 and the clamping rods 52, 53 provided near the side portions of the transport chains 54, 55. The roots of the culm are clamped and conveyed. The clamping rods 52 and 53 are attached to a stay 51 provided on a support frame 37 so as to be able to freely move in and out of each of the transport chain 54 and the transport chain 55. Since the stay 51 is formed so as to protrude substantially horizontally with respect to the lower portion 38, a space is formed below the sandwiching rods 52 and 53 to smoothly transport the grain culm.

　また、前記ステー５１は下部３８に対してハの字形状に形成しているから、万一、挾扼杆５２、５３と搬送チエン５４、５５の間に搬送穀稈が詰まっても、穀稈を搬送しようとする荷重は、下部３８の左右側に突出するステー５１に均等に掛り、ステー５１およびステー５１の取付部分の破損を防止する。 In addition, since the stay 51 is formed in a C-shape with respect to the lower portion 38, even if the transported grain culm is clogged between the sandwiching rods 52, 53 and the transport chains 54, 55, the grain culm can be used. Is equally applied to the stays 51 projecting to the left and right sides of the lower portion 38, thereby preventing damage to the stays 51 and the mounting portions of the stays 51.

　また、５条刈の刈取部５における実施例でも、支持フレーム４５に設けたステー６０は、前部支持フレーム４５の後側下部４８にハの字形状に形成し、かつ、略水平方向に突出するように形成しているから、同様の作用を奏する。 Also, in the embodiment of the cutting section 5 of the five-row cutting, the stay 60 provided on the support frame 45 is formed in a C-shape on the rear lower portion 48 of the front support frame 45 and projects substantially horizontally. Therefore, the same operation is achieved.

　また、前記支持フレーム４５は、側方からみると、Ｓ型形状に形成され、支持フレーム４５の前側水平部前側下部４６も上方からみると逆Ｌ型形状であり、前側下部４６の先端は前記分草杆１４に固定し、前側下部４６の屈曲した横杆部横杆部４７の端部には伝動筒伝動筒５０の中間部を固定し、伝動筒５０には前記ラグ式穂先掻込装置１７および株元掻込スターホイル装置１８のうち中央右側に位置する一対のラグ式穂先掻込装置１７および株元掻込スターホイル装置１８を取付けているから、ラグ式穂先掻込装置１７および株元掻込スターホイル装置１８の取付部分より離れた位置に、前記右株元側集束搬送装置２０ｂおよび後株元側集束搬送装置２４の挾扼杆５８と、前記中間株元側集束搬送装置２０ｃの挾扼杆５９とを取付けたステー６０を設けることができ、ラグ式穂先掻込装置１７および株元掻込スターホイル装置１８と、前記右側株元側集束搬送装置２０ｂおよび後株元側集束搬送装置２４と、前記中間の株元側集束搬送装置２０ｃのそれぞれのメンテナンスを容易に行なえる。 The support frame 45 is formed in an S-shape when viewed from the side, and a front horizontal portion front lower portion 46 of the support frame 45 is also an inverted L-shape when viewed from above. The middle part of the transmission cylinder 50 is fixed to the weeding rod 14 and the end of the bent horizontal rod 47 of the front lower part 46 is fixed to the transmission cylinder 50. A pair of lug-type head scraping devices 17 and 18 located on the right side of the center among the 17 and the stock source scraping star wheel devices 18 are attached, so that the lug-type tip scraping device 17 and the stock are removed. At a position distant from the mounting portion of the former scraping star wheel device 18, the clamping rod 58 of the right stock base side conveyer 20b and the rear stock former conveyer 24, and the intermediate base base conveyer 20c.
