Further, since the intermediate portion of the narrow guide 88 is supported by the turning arm 89, the rigidity of the narrow guide 88 is also improved. Further, since the stay 90 is fixed to the weed ridge 14 and the cutting blade frame 13, it constitutes a part of the strength member. In addition, the narrow guide 88 is rotated and stored in the cutting part 5 side when not in use.

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. Since it is the above configuration, when the aircraft is moved forward, the weeds are divided by each weed body 15, the weed culms are pulled by the pulling device 16, and the pulled culms are cut by the cutting blade 19, It is scraped backward by the lag type scooping device 17 and the stock-curing starfoil device 18, the stock is held by the right and left stock-side converging and transporting devices 20a and 20b, and the stock side is transported by the stock-side transport device 21. Is transferred to the transfer point A at one location through the transfer path and transferred to the stock takeover transfer device 22 and the tip transfer device 23, and is transferred to the threshing room side by the stock takeover transfer device 22 and the tip transfer transfer device 23. The cereal supply device of the part is taken over, and is supplied to the threshing room by the cereal supply device and threshed. In the case of 5-row cutting, the stock is held by the right and left middle stocker-side converging and transporting devices 20a, 20b, and 20c, the tip side is transported by the head-side transporting device 21, and the right stocker-side converging and transporting device 20b and the middle The cereals conveyed by the stocker-side converging and transporting device 20c are transported to a single takeover point A by the rear stocker-side converging and transporting device 24, and are taken over by the stocker takeover and transporting device 22 and the tip takeover and transporting device 23.
