しかして、前記第二刈取装置２２を機体前方へ回動させ、該第二刈取装置２２側の下部ギヤケース３３の端面と第一刈取装置２１側の下部ギヤケース３３の端面とが接合し、第二刈取装置２２側の最も機体中央寄りの分草杆３６と第一刈取装置２１側の最も機体中央寄りの分草杆３６とが平行に並ぶ状態で、前記第二刈取装置２２側のフック４８，４８，４８が、図２および図４に示すように、第一刈取装置２１側の分草杆３６と下部ギヤケース３３の端部に設けた被係合部５０とに係合し、４条刈の第一刈取装置２１と４条刈の第二刈取装置２２とが一体化して、８条刈の刈幅を有する刈取装置３が形成される。これによって、刈取作業の能率を向上させることができる。また、このように第一刈取装置２１の分草杆３６と第二刈取装置２２の分草杆３６とを連結するフック４８，４８が分草体３６の後側に配置されるために、刈取作業時においてこのフック４８，４８に穀稈が引っ掛かりにくく、刈取作業を円滑に行うことができる。また、フック４８，４８，４８を連結解除して第一刈取装置２１と第二刈取装置２２とを分離し、第二刈取装置２２を側方回動させることによって、この第一刈取装置２１および第二刈取装置２２の内部のメンテナンスを容易に行うことができる。また、第二刈取装置２２を完全に取り外すことによって幅を小さくし、このコンバインと取り外した第二刈取装置２２とを輸送用トラックの荷台へ容易に積載することができる。また、分草杆３６を下方回動させることによってフック４８，４８の連結操作および連結解除操作が行ない易くなり、刈取作業からコンバインの輸送作業への移行が短時間で行えて、輸送作業を含めた作業能率の向上を図ることができる。 Thus, the second reaping device 22 is rotated forward, and the end surface of the lower gear case 33 on the second reaping device 22 side and the end surface of the lower gear case 33 on the first reaping device 21 side are joined, In a state in which the weed pod 36 closest to the center of the body on the reaping device 22 side and the weed tub 36 closest to the center of the body on the side of the first reaping device 21 are arranged in parallel, the hooks 48 on the second reaping device 22 side, As shown in FIGS. 2 and 4, 48 and 48 are engaged with the weed ridge 36 on the first reaping device 21 side and the engaged portion 50 provided at the end of the lower gear case 33, so The first cutting device 21 and the second cutting device 22 of four-row cutting are integrated to form the cutting device 3 having a cutting width of eight cuttings. Thereby, the efficiency of the cutting operation can be improved. In addition, since the hooks 48 and 48 that connect the weed pod 36 of the first reaping device 21 and the weed pod 36 of the second reaping device 22 are arranged on the rear side of the weed body 36 in this way, the reaping operation is performed. At this time, the grains 48 are not easily caught by the hooks 48 and 48, and the cutting operation can be performed smoothly. Further, the first reaping device 21 and the second reaping device 22 are separated by disconnecting the hooks 48, 48, 48, and the second reaping device 22 is laterally rotated. Maintenance inside the second reaping device 22 can be easily performed. Moreover, the width can be reduced by completely removing the second reaping device 22, and the combine and the removed second reaping device 22 can be easily loaded on the loading platform of the transport truck. Further, by rotating the weed fence 36 downwardly, the hooks 48 and 48 can be easily connected and disconnected, and the transition from the cutting operation to the transporting operation of the combine can be performed in a short time. The work efficiency can be improved.

図６に示すように、引起装置３９を、その上部の横伝動軸の軸心Ｐを中心として上昇回動可能に構成する。引起作業位置での位置保持は、分草杆３６に設けたフック５０によって引起装置３９の背面側下部を係止する構成である。このフック５０による係止を解除すると、引起装置３９が上昇回動可能な状態となる。そして、引起装置３９を手動操作で上昇回動させた後、該引起装置３９の背面側に折り畳んで収納していた屈折リンク式の位置保持装置５１を支点越えさせて伸長させることにより、この引起装置３９を上昇回動位置で支える構成である。尚、前記位置保持装置５１は、上側リンク５１ａと下側リンク５１ｂとを回動自在に連結して構成する。また、分草体３７は、その前後方向中間部の背面側を分草杆３６の先端部に対して左右方向の軸芯Ｑ周りに回動可能に取り付け、手動操作によって前後回動するように構成する。これにより、分草体３７を前方回動させれば、該分草体３７が引起装置３９の上昇回動軌跡Ｘから外側に退避し、該分草体３７と引起装置３９とが干渉しなくなる。 As shown in FIG. 6, the pulling device 39 is configured so as to be capable of ascending and turning about the axis P of the lateral transmission shaft on the upper side thereof. The position holding at the pulling work position is a configuration in which the lower portion on the back side of the pulling device 39 is locked by the hook 50 provided on the weed ridge 36. When the locking by the hook 50 is released, the pulling device 39 is in a state in which it can be rotated upward. Then, after the pulling device 39 is lifted and rotated manually, the retraction link type position holding device 51 which is folded and stored on the back side of the pulling device 39 is extended beyond the fulcrum to thereby extend the pulling device 39. It is the structure which supports the apparatus 39 in a raise rotation position. The position holding device 51 is configured by rotatably connecting an upper link 51a and a lower link 51b. Further, the weed body 37 is configured such that the back side of the middle portion in the front-rear direction is attached to the front end of the weed ridge 36 so as to be rotatable around the axis Q in the left-right direction, and is rotated back and forth by manual operation. To do. Thus, if the weed body 37 is rotated forward, the weed body 37 is retracted outward from the ascending rotation trajectory X of the pulling device 39, and the weed body 37 and the pulling device 39 do not interfere with each other.

また、図７に示すように、分草体３７を支持する所定長さの前部分草杆３６ａを設け、該前部分草杆３６ａの後端部を分草杆３６の前端部に左右方向の軸芯Ｒ周りに軸着して取り付けてもよい。これにより、分草体３７を前方回動させた際に、この分草体３７を引起装置３９の上昇回動軌跡Ｘからより大きく退避させることができる。 As shown in FIG. 7, a front portion grass ridge 36 a having a predetermined length that supports the weed body 37 is provided, and the rear end portion of the front portion grass bud 36 a is connected to the front end portion of the weed fold 36 as a horizontal axis. You may attach to the circumference | surroundings of the core R. As a result, when the weed body 37 is rotated forward, the weed body 37 can be largely retracted from the ascending rotation locus X of the pulling device 39.

また、図８、図９に示すように、縦引起装置５２を引起装置３９と一体で上昇回動するように構成したものである。この場合、引起装置３９と縦引起装置５２とを所定長の前側分草杆３６ｂに一体的に取り付けて上昇回動可能とする構成である。 Further, as shown in FIGS. 8 and 9, the vertical pulling device 52 is configured to rotate upward integrally with the pulling device 39. In this case, the pulling device 39 and the vertical pulling device 52 are integrally attached to a predetermined length of the front weed fence 36b so as to be able to rotate upward.

尚、５３はラグベルト式の掻込装置である。
また、図１０、図１１に示すように、４基の引起装置３９を一体的に上昇回動させられるように構成してもよい。このように構成すれば、８条刈の刈幅を有する刈取装置であっても、４条分の引起装置３９を一体的に上昇回動させて開放できるため、刈取装置内部のメンテナンスを容易に行うことができる。また、このように刈取装置６を左右方向に２分割して開放する構成をも備えるため、刈取装置内部のメンテナンスを更に容易に行うことができる。 Reference numeral 53 denotes a lag belt type scraping device.
Further, as shown in FIGS. 10 and 11, the four pulling devices 39 may be configured to be integrally raised and rotated. If comprised in this way, even if it is a cutting device which has the cutting width | variety of 8-row cutting, since the pulling device 39 for 4 strips can be lifted up integrally and opened, maintenance inside a cutting device is easy. It can be carried out. In addition, since the reaping device 6 is also provided with a structure in which the reaping device 6 is divided and opened in the left-right direction, maintenance inside the reaping device can be performed more easily.

また、図１２、図１３に示すように、８基の全ての引起装置３９を一体的に上昇回動させらるように構成してもよい。このように構成することによって、多条刈の刈取装置のメンテナンスを容易に行えるようになり、刈取作業の能率を向上させることができる。 Further, as shown in FIGS. 12 and 13, all of the eight pulling devices 39 may be integrally raised and rotated. By comprising in this way, the maintenance of the multi-row mowing apparatus can be easily performed, and the efficiency of the mowing work can be improved.
