上記従来構成は、巻付き防止カバーが駆動軸の外周を覆う状態で筒状に形成されるものであるから、巻付き防止カバーを装着する場合、あるいは、修理交換等のメンテナンス作業を行う場合等において、煩わしい手間のかかる作業が必要となっていた。   In the above conventional configuration, the wrapping prevention cover is formed in a cylindrical shape so as to cover the outer periphery of the drive shaft. Therefore, when the wrapping prevention cover is attached, or when maintenance work such as repair and replacement is performed. However, a troublesome and time-consuming work is required.

すなわち、巻付き防止カバーを装着したり、メンテナンスのために取り外したりするときには、少なくとも駆動軸の一方側の軸端部を開放させた状態で、巻付き防止カバーを軸芯方向にスライドさせて駆動軸の外周側に外挿したり、外方に引き出す等の煩わしい作業が必要となる。その結果、巻付き防止カバーの取り付け作業や取り外し作業が手間のかかるものとなっていた。   In other words, when the anti-winding cover is attached or removed for maintenance, the anti-winding cover is slid in the axial direction with at least one shaft end of the drive shaft open. Troublesome work such as extrapolation to the outer periphery side of the shaft or drawing out to the outside is required. As a result, the work of attaching and removing the wrapping prevention cover is troublesome.

そこで、巻付き防止カバーの取り付けや取り外しを能率よく行えるようにすることが望まれていた。   Therefore, it has been desired to efficiently attach and remove the wrapping prevention cover.

前記巻付き防止カバーが、周方向に分割された複数の分割カバー体にて構成されている点にある。
The characteristic configuration of the ordinary combine according to the present invention is as follows:
A feeder is provided that conveys the harvested cereals harvested by the harvesting part at the front of the aircraft toward the rear of the aircraft,
The feeder is provided with a cylindrical feeder case for transferring cereal grains, a laterally lower rotary shaft installed inside the lower side of the feeder case in the transport direction, and an interval in the axial direction of the lower rotary shaft. A pair of lower-side extension wheels provided on the lower-side rotating shaft, a lateral upper-side rotating shaft erected on the upper side in the conveying direction of the feeder case, and the upper-side rotating shaft. A pair of upper side tensioning wheels provided, a lower side tensioning wheel and the upper side tensioning wheels wound around the upper side tensioning wheel and spaced apart in the axial direction. A cylindrical winding that is extrapolated to the lower-side rotating shaft between the endless rotating body, a plurality of conveying members that are installed horizontally across the pair of endless rotating bodies, and the pair of lower-side extending wheels. With an anti-stick cover,
The winding prevention cover is constituted by a plurality of divided cover bodies divided in the circumferential direction.

本発明によれば、巻付き防止カバーを下手側回転軸の外周側に装着するときは、下手側回転軸の軸芯方向両側部が軸受け部材により支持されている状態で、下手側回転軸の径方向外方側から複数の分割カバー体を各別に装着することができる。巻付き防止カバーを取り外す場合にも、同様に、下手側回転軸の径方向外方側に向けて複数の分割カバー体を各別に取り外すことができる。   According to the present invention, when the anti-winding cover is attached to the outer peripheral side of the lower rotation shaft, both sides in the axial direction of the lower rotation shaft are supported by the bearing member, and the lower rotation shaft A plurality of divided cover bodies can be mounted separately from the radially outer side. Similarly, when removing the wrapping prevention cover, the plurality of divided cover bodies can be removed separately toward the radially outward side of the lower-side rotating shaft.

その結果、下手側回転軸の軸端を開放させて、巻付き防止カバーを軸芯方向にスライドさせて外挿したり外方に引き出す等の煩わしい作業が不要であり、巻付き防止カバーの取り付けや取り外しを能率よく行えるようにすることが可能となった。   As a result, there is no need for troublesome operations such as opening the shaft end of the lower rotation shaft and sliding the anti-winding cover in the axial direction to pull it out or pull it out. It has become possible to perform the removal efficiently.

本発明においては、
前記下手側回転軸における前記一対の下手側張設用輪体同士の横方向中間側に隣接する箇所に位置して前記下手側回転軸に相対回転自在に支持される一対のボス部材と、一対の前記ボス部材同士を連結する連結部材とが備えられ、
前記巻付き防止カバーが前記連結部材を覆っていると好適である。

It is preferable that the winding prevention cover covers the connecting member.

本構成によれば、一対の下手側張設用輪体夫々の横方向中間側に隣接する箇所にボス部材が備えられ、一対のボス部材は連結部材により連結される。ボス部材は下手側回転軸に相対回転自在に支持されるので、下手側張設用輪体の近傍において下手側回転軸の外周部に排ワラ等が巻付いて堆積すること回避することができる。そして、連結部材の外周側が巻付き防止カバーにて覆われるので、連結部材が外方に露出することがなく、刈取穀稈が引っ掛かり堆積し難いものにできる。   According to this configuration, the boss member is provided at a location adjacent to the intermediate side in the lateral direction of each of the pair of lower-side extending wheels, and the pair of boss members are connected by the connecting member. Since the boss member is rotatably supported by the lower-side rotating shaft, it is possible to avoid the exhaust wall or the like from being wound around the outer peripheral portion of the lower-side rotating shaft in the vicinity of the lower-side tensioning wheel. . And since the outer peripheral side of a connection member is covered with a wrapping prevention cover, a connection member is not exposed outside, and it can be made into the thing by which a harvested grain potato is caught and it does not accumulate easily.

本発明においては、前記巻付き防止カバーが前記連結部材に支持されていると好適である。   In the present invention, it is preferable that the wrapping prevention cover is supported by the connecting member.

本構成によれば、一対のボス部材を連結するための連結部材を有効に利用して、巻付き防止カバーを安定的に支持することができる。   According to this configuration, the wrapping prevention cover can be stably supported by effectively using the connecting member for connecting the pair of boss members.

本発明においては、前記連結部材に、前記分割カバー体の周方向端部と重なり合う取付面が備えられていると好適である。   In the present invention, it is preferable that the connecting member is provided with an attachment surface that overlaps with a circumferential end of the divided cover body.

本構成によれば、分割カバー体の周方向端部を取付面に重ね合わせることで、連結部材と分割カバー体とを連結し易いものとなる。   According to this structure, it becomes easy to connect a connection member and a division | segmentation cover body by superimposing the circumferential direction edge part of a division | segmentation cover body on a mounting surface.

本発明においては、前記連結部材のうち前記巻付き防止カバーの周方向における両端部に、前記取付面が備えられていると好適である。   In this invention, it is suitable when the said attachment surface is provided in the both ends in the circumferential direction of the said winding prevention cover among the said connection members.

本構成によれば、巻付き防止カバーを周方向における両端に備えられた取付面の夫々に連結することで、巻付き防止カバーを安定的に支持することができる。   According to this configuration, the wrapping prevention cover can be stably supported by connecting the wrapping prevention cover to each of the attachment surfaces provided at both ends in the circumferential direction.

本発明においては、前記分割カバー体における前記取付面への複数の締結箇所が、前記下手側回転軸の軸芯方向に沿って並ぶ状態で設けられていると好適である。   In the present invention, it is preferable that a plurality of fastening portions to the mounting surface in the divided cover body are provided in a state of being aligned along the axial direction of the lower-side rotation shaft.

本構成によれば、分割カバー体が複数の締結箇所にて取付面に強固に連結することができる。しかも、複数の締結箇所が下手側回転軸の軸芯方向に沿って並ぶ状態で設けられるので、取付に必要なスペースを周方向に沿ってコンパクトなものにできる。   According to this structure, a division | segmentation cover body can be firmly connected to an attachment surface in a some fastening location. In addition, since a plurality of fastening locations are provided in a state of being aligned along the axial direction of the lower-side rotation shaft, the space required for mounting can be made compact along the circumferential direction.

本発明においては、前記分割カバー体の周方向端部の両側又は一方において、前記分割カバー体のうち外周側に位置する前記分割カバー体が隣り合う前記分割カバー体と重なり合っていない箇所で前記取付面に締結されていると好適である。   In the present invention, on either side or one of the circumferential end portions of the divided cover body, the attachment is performed at a location where the divided cover body located on the outer peripheral side of the divided cover body does not overlap with the adjacent divided cover body. It is preferable that it is fastened to the surface.

本構成によれば、隣り合う分割カバー体と重なり合っていない箇所にて取付面に締結されている分割カバー体は、取付面との締結を解除すると、隣り合う分割カバー体と取付面との連結状態を維持したまま、当該分割カバー体だけを取り外すことができる。   According to this configuration, when the split cover body that is fastened to the mounting surface at a location that does not overlap with the adjacent split cover body is released from the fastening with the mounting surface, the adjacent split cover body and the mounting surface are connected. Only the division | segmentation cover body can be removed, maintaining a state.

本発明においては、前記連結部材が、前記各ボス部材に対して、一対の前記ボス部材の中間部側から各ボス部材側に向けて前記軸芯方向に沿ってボルト連結され、
前記巻付き防止カバーのうちのいずれかの前記分割カバー体によって、前記連結部材と前記ボス部材との連結箇所が覆われていると好適である。
In the present invention, the connecting member is bolt-connected to the boss members along the axial direction from the intermediate part side of the pair of boss members toward the boss member side,
It is preferable that the connecting portion between the connecting member and the boss member is covered by the divided cover body of any one of the winding prevention covers.

本構成によれば、連結部材は、一対のボス部材の中間部側から各ボス部材側に向けて軸芯方向に沿ってボルト連結される。このように軸芯方向に沿ってボルト連結することで、連結部材を径方向に沿ってコンパクトな形状に収めることができる。   According to this configuration, the connecting member is bolt-connected along the axial direction from the middle side of the pair of boss members toward each boss member side. By connecting the bolts along the axial direction in this way, the connecting member can be accommodated in a compact shape along the radial direction.

巻付き防止カバーによって連結部材とボス部材との連結箇所を覆うようにしたので、巻付き防止カバーは一対のボス部材にわたって設けられることになる。このように連結箇所の外周側が巻付き防止カバーにて覆われるので、連結箇所が外方に露出することがなく、刈取穀稈が引っ掛かり堆積し難いものにできる。   Since the connection portion between the connecting member and the boss member is covered by the wrapping prevention cover, the wrapping prevention cover is provided over the pair of boss members. Thus, since the outer peripheral side of a connection location is covered with a wrapping prevention cover, a connection location does not expose outside, and it can be made difficult for a harvested cereal to be caught and deposited.

本発明においては、前記連結部材を覆う前記分割カバー体の上部面が、前記無端回動体の直線移動経路に沿う姿勢又は略沿う姿勢に形成されていると好適である。   In the present invention, it is preferable that the upper surface of the divided cover body covering the connecting member is formed in a posture along or substantially along a linear movement path of the endless rotating body.

本構成によれば、連結部材を覆う分割カバー体の上部面と無端回動体の直線移動経路とが平行又は略平行に並ぶので、それらの間に充分大きな間隔をあけた状態になる。その結果、分割カバー体の上部面と無端回動体の間にワラ屑等が引っ掛かり堆積することを回避し易い。   According to this structure, since the upper surface of the division | segmentation cover body which covers a connection member and the linear movement path | route of an endless rotation body are located in parallel or substantially parallel, it will be in the state which opened the space | interval large enough between them. As a result, it is easy to avoid trapping and accumulating dust and the like between the upper surface of the divided cover body and the endless rotating body.

本発明においては、前記連結部材を覆う前記分割カバー体の上部面が、前記フィーダケースの上手側ほど前記無端回動体の下側の直線移動経路に近づくように傾斜する傾斜面に形成されていると好適である。   In the present invention, the upper surface of the divided cover body that covers the connecting member is formed on an inclined surface that is inclined so as to approach the linear movement path on the lower side of the endless rotating body toward the upper side of the feeder case. It is preferable.

本構成によれば、分割カバー体の上部面が傾斜面になっているので、ワラ屑等が無端回動体と連回りして下手側張設用輪体の上方側搬送経路にまで持ち割り搬送されて、分割カバー体の上部面に載置されるようなことがあっても、ワラ屑は傾斜姿勢の分割カバー体の上部面によって流下案内されて下方に落下する。その結果、無端回動帯による搬送作用を受けて搬送方向下手側に適切に搬送することができる。   According to this configuration, since the upper surface of the divided cover body is an inclined surface, straw scraps and the like are connected to the endless rotating body and are transported to the upper transport path of the lower-side tension ring. Then, even if it is placed on the upper surface of the divided cover body, the straw scraps are guided down by the upper surface of the inclined divided cover body and fall downward. As a result, it can be transported appropriately to the lower side in the transport direction under the transport action of the endless rotation belt.

本発明においては、前記下手側回転軸よりも搬送方向上手側に位置して前記フィーダケースの内部に架設された横向きのフレーム体と、
前記巻付き防止カバーと前記フレーム体とにわたって設けられた接続部材とが備えられ、
前記巻付き防止カバーが、前記接続部材によって回り止めされた状態で前記フィーダケースに支持されていると好適である。
In the present invention, a lateral frame body that is positioned on the upper side in the transport direction than the lower-side rotating shaft and is installed inside the feeder case;
A connection member provided across the wrapping prevention cover and the frame body;
It is preferable that the wrapping prevention cover is supported by the feeder case in a state of being prevented from rotating by the connection member.

本構成によれば、フレーム体と巻付き防止カバーとにわたって備えられた接続部材により巻付き防止カバーが回り止めされる。このように、フィーダケースの内部に架設される状態で備えられる横向きのフレーム体を利用して、簡単な構成で巻付き防止カバーを回り止めすることができる。   According to this configuration, the anti-winding cover is prevented from rotating by the connecting member provided over the frame body and the anti-winding cover. As described above, the anti-winding cover can be prevented from being rotated with a simple configuration by using the horizontal frame body provided in a state of being installed inside the feeder case.

本発明においては、前記接続部材が、前記複数の分割カバー体のうちのいずれかと前記フレーム体とにわたって設けられていると好適である。   In the present invention, it is preferable that the connection member is provided over any one of the plurality of divided cover bodies and the frame body.

本構成によれば、フレーム体に近い位置にある分割カバー体とフレーム体とを接続することで、接続部材を短くすることができ、構造の簡素化を図ることができる。   According to this configuration, by connecting the divided cover body and the frame body that are close to the frame body, the connecting member can be shortened, and the structure can be simplified.

本発明においては、前記接続部材に、前記巻付き防止カバーに連結された第一接続体と、前記第一接続体に連結されるとともに前記フレーム体に接続された第二接続体とが備えられていると好適である。   In the present invention, the connection member includes a first connection body connected to the wrapping prevention cover, and a second connection body connected to the first connection body and connected to the frame body. It is preferable that

接続部材は、巻付き防止カバーを回り止めするものであるから、例えば、接続部材が、巻付き防止カバーからフレーム体にわたって一連に連なる一体物にて形成されるものであれば、フィーダが組み付けられた後に、点検修理等のために接続部材を取り外す場合、下手側回転軸の軸芯周りで回動させることができないので、着脱作動が行い難いものになるおそれがある。   Since the connecting member prevents the wrapping prevention cover from rotating, for example, if the connection member is formed of a continuous body that is continuous from the wrapping prevention cover to the frame body, the feeder is assembled. After that, when removing the connecting member for inspection and repair, it is difficult to perform the attaching / detaching operation because the connecting member cannot be rotated around the axis of the lower-side rotating shaft.

そこで、本構成によれば、接続部材が、巻付き防止カバーに連結された第一接続体と、フレーム体に接続された第二接続体とを備えるので、メンテナンス作業において接続部材を着脱させるときは、第一接続体と第二接続体との連結を解除させたり、相対的な姿勢を変更させる等により、着脱作業を容易に行うことができる。   Therefore, according to this configuration, the connection member includes the first connection body connected to the anti-wrapping cover and the second connection body connected to the frame body, so that the connection member can be attached and detached in maintenance work. The attachment / detachment work can be easily performed by releasing the connection between the first connection body and the second connection body or changing the relative posture.

本発明においては、前記接続部材は、前記巻付き防止カバーと前記フレーム体とにわたって設けられた縦向き姿勢の板状体であると好適である。   In the present invention, it is preferable that the connection member is a plate-like body in a vertical orientation provided across the wrapping prevention cover and the frame body.

本構成によれば、接続部材は縦向き姿勢の板状体にて構成されるから、平面視で幅狭であり、巻付き防止カバーとフレーム体との間から落下するワラ屑等が引っ掛かり堆積するおそれが少ないものとなる。   According to this configuration, since the connecting member is formed of a vertically oriented plate-like body, it is narrow in a plan view, and trapping and the like falling from between the wrapping prevention cover and the frame body are caught. There is little possibility to do.

本発明においては、前記巻付き防止カバーと前記フレーム体との間に、前記一対の下手側張設用輪体の間にわたって上下に開放された開放空間が形成されていると好適である。   In the present invention, it is preferable that an open space that is open up and down is formed between the pair of lower-side extending rings between the wrapping prevention cover and the frame body.

本構成によれば、刈取穀稈が下手側張設用輪体と無端回動体との間に挟み込まれ、下手側張設用輪体と共に連れ回りしながら上方側の移動経路に移動することがあっても、開放空間を通して無端回動体の下側に位置する回動経路に落下する。その結果、回動経路に落下した刈取穀稈は、そこを通過する無端回動帯によって搬送方向下手側に向けて搬送され、滞留することを防止できる。   According to this configuration, the harvested cereal culm is sandwiched between the lower-side tension ring and the endless rotating body, and moves along the lower-side tension ring while moving with the lower-side tension ring. Even if it falls, it falls to the rotation path located under the endless rotation body through the open space. As a result, the harvested cereal grains that have fallen on the rotation path are conveyed toward the lower side in the conveyance direction by the endless rotation band passing therethrough, and can be prevented from staying.

本発明においては、前記接続部材が、前記巻付き防止カバーと前記フレーム体とにわたって設けられた横向き姿勢の板状体であると好適である。   In the present invention, it is preferable that the connecting member is a plate-like body in a lateral orientation provided across the wrapping prevention cover and the frame body.

本構成によれば、長稈のワラ屑等が筒状の巻付き防止カバーに巻き付き始めたときに、横向き姿勢の板状体からなる接続部材により、軸芯方向に広い範囲にわたって、巻き付き始めたワラ屑を受止めることができる。その結果、ワラ屑等が筒状の巻付き防止カバーに巻き付くことを回避することができる。   According to this configuration, when long straw scraps or the like start to wind around the cylindrical winding prevention cover, the connecting member made of a plate-like body in a lateral orientation starts to wind over a wide range in the axial direction. Can catch straw scraps. As a result, it is possible to avoid that the waste scraps and the like are wound around the cylindrical winding prevention cover.

本発明においては、前記巻付き防止カバーに、前記接続部材を載置支持するカバー側載置支持部が備えられていると好適である。   In the present invention, it is preferable that the wrapping prevention cover is provided with a cover side placement support portion for placing and supporting the connection member.

本構成によれば、接続部材の巻付き防止カバー側の端部がカバー側載置支持部に載置された状態で安定的に支持される。   According to this configuration, the end of the connection member on the wrapping prevention cover side is stably supported in a state of being placed on the cover side placement support portion.

本発明においては、前記フレーム体に、前記接続部材を載置支持するフレーム側載置支持部が備えられていると好適である。   In the present invention, it is preferable that the frame body is provided with a frame-side mounting support portion for mounting and supporting the connection member.

本構成によれば、接続部材のフレーム体側の端部がフレーム側載置支持部に載置された状態で安定的に支持される。   According to this structure, the edge part by the side of the frame body of a connection member is stably supported in the state mounted in the frame side mounting support part.

本発明においては、前記一対の下手側張設用輪体夫々の前記軸芯方向外方側に、前記下手側回転軸を内挿して回転自在に支持する筒状支持部が備えられ、
前記下手側張設用輪体の前記軸芯方向外方側の側面に、前記筒状支持部の端部を覆う筒状の覆い部が備えられ、
前記筒状支持部の外周部のうち、前記覆い部によって覆われる箇所に、前記覆い部の内周部に向かって立ち上がる環状の鍔状部が備えられていると好適である。
In the present invention, a cylindrical support portion is provided on the outer side in the axial direction of each of the pair of lower-side extending wheels, and the lower-side rotation shaft is inserted and rotatably supported.
A cylindrical cover portion that covers an end portion of the cylindrical support portion is provided on a side surface on the outer side in the axial direction of the lower-side extending ring body,
It is preferable that an annular hook-shaped portion that rises toward the inner peripheral portion of the cover portion is provided at a location covered by the cover portion in the outer peripheral portion of the cylindrical support portion.

巻付き防止カバー68とフレーム体56とにわたって設けられた縦向き姿勢の板状体からなる接続部材75にて巻付き防止カバー68が回り止めされている。フレーム体56は左右方向両側部がフィーダケース42に固定されているので、巻付き防止カバー68は、回り止めされた状態でフィーダケース42に支持されることになる。   The anti-winding cover 68 is prevented from rotating by a connecting member 75 made of a plate-like body in a vertically oriented posture provided across the anti-winding cover 68 and the frame body 56. Since both sides of the frame body 56 are fixed to the feeder case 42, the anti-winding cover 68 is supported by the feeder case 42 in a state of being prevented from rotating.

接続部材75が、連結部材63を覆う第二分割カバー体70とフレーム体56とにわたって設けられている。図6に示すように、接続部材75は、夫々が板状体にて形成される第一接続体76と第二接続体77とに分割されている。第一接続体76は、第二分割カバー体70に対して軸芯方向の中央位置において、溶接により一体的に固定されている。第二接続体77は、第一接続体76と2本のボルト78で連結されており、フレーム体56に対向する箇所には、フレーム体56の円弧状の外周面に沿うように円弧状の凹入部79が形成されている。   A connecting member 75 is provided across the second divided cover body 70 and the frame body 56 that cover the connecting member 63. As shown in FIG. 6, the connection member 75 is divided into a first connection body 76 and a second connection body 77 each formed of a plate-like body. The first connection body 76 is integrally fixed to the second divided cover body 70 by welding at a central position in the axial direction. The second connection body 77 is connected to the first connection body 76 by two bolts 78, and the arc connection is provided along the arc-shaped outer peripheral surface of the frame body 56 at a position facing the frame body 56. A recessed portion 79 is formed.

第一接続体76は、第二分割カバー体70に固定されているから、第一接続体76と第二接続体77とが連結されていない状態では、駆動軸44の軸芯まわりの周方向での位置は任意に変更することができる。そして、第二接続体77の凹入部79がフレーム体56の円弧状の外周面に沿うように当て付けられた状態で、第一接続体76と第二接続体77とをボルト78で連結することにより、第一接続体76の周方向での位置が定まることになる。   Since the first connection body 76 is fixed to the second divided cover body 70, the circumferential direction around the axis of the drive shaft 44 in a state where the first connection body 76 and the second connection body 77 are not coupled. The position at can be changed arbitrarily. Then, the first connection body 76 and the second connection body 77 are coupled with the bolt 78 in a state where the recessed portion 79 of the second connection body 77 is applied along the arcuate outer peripheral surface of the frame body 56. As a result, the position of the first connecting body 76 in the circumferential direction is determined.

第一接続体76と第二接続体77との間のボルト連結箇所は、図示はしないが、いずれかのボルト挿通孔が長孔に形成されている。第二接続体77の第一接続体76に対する相対位置を変更調整して、円弧状の凹入部79がフレーム体56の外表面に接当する状態でボルト78を締結して固定することができる。   Although the bolt connection location between the 1st connection body 76 and the 2nd connection body 77 is not illustrated, either bolt insertion hole is formed in the long hole. The relative position of the second connection body 77 with respect to the first connection body 76 can be changed and adjusted, and the bolt 78 can be fastened and fixed in a state where the arcuate recess 79 is in contact with the outer surface of the frame body 56. .

その結果、接続部材75が、ガタツキの生じない状態で、連結部材63を覆う第二分割カバー体70とフレーム体56とにわたって設けられて、巻付き防止カバー68を回り止めすることができる。   As a result, the connection member 75 is provided across the second divided cover body 70 and the frame body 56 that cover the coupling member 63 in a state where there is no backlash, and the anti-winding cover 68 can be prevented from rotating.

図3,6に示すように、連結部材63を覆う第二分割カバー体70の上部面70b(上側の周方向端部70a)が、無端回動チェーン48の直線移動経路に沿う姿勢又は略沿う姿勢に形成されている。第二分割カバー体70の両側の周方向端部70aは平行姿勢であり、無端回動チェーン48の下側の直線移動経路Kと第二分割カバー体70の周方向端部70aとの間が開放された状態となる。従って、それらの間で刈取穀稈が搬送詰まりを起して堆積することを回避できる。尚、連結用のボルト72,73,74の頭部は、刈取穀稈が引っ掛かるおそれが少なくなるように、滑らかな円弧状に形成されている。   As shown in FIGS. 3 and 6, the upper surface 70 b (upper circumferential end 70 a) of the second divided cover body 70 covering the connecting member 63 is along or substantially along the linear movement path of the endless rotating chain 48. It is formed in a posture. The circumferential end portions 70a on both sides of the second divided cover body 70 are in a parallel posture, and the space between the lower linear movement path K of the endless rotating chain 48 and the circumferential end portion 70a of the second divided cover body 70 is between. It will be in an open state. Therefore, it can be avoided that the harvested cereal culm causes the transport clogging between them and accumulates. Note that the heads of the connecting bolts 72, 73, 74 are formed in a smooth arc shape so as to reduce the possibility that the harvested culm will be caught.

図4に示すように、接続部材75は縦向き姿勢の板状体にて構成されるので平面視で幅狭である。従って、巻付き防止カバー68とフレーム体56との間には、一対の駆動スプロケット46の間にわたって上下に開放された開放空間Qが形成されている。   As shown in FIG. 4, the connection member 75 is configured by a plate-like body in a vertically oriented posture, and thus is narrow in plan view. Therefore, an open space Q that is opened up and down across the pair of drive sprockets 46 is formed between the wrapping prevention cover 68 and the frame body 56.

このように巻付き防止カバー68とフレーム体56との間に開放空間Qが形成されているから、長稈の刈取穀稈が、無端回動チェーン48と駆動スプロケット46とにより挟まれて連れ回りしながら上方側の移動経路に移動して、挟み込みが解除されて刈取穀稈が下方に落下することがあっても、刈取穀稈は、開放空間Qを通して無端回動チェーン48の下側に位置する直線移動経路Kに落下するので他の刈取穀稈と共に後方に搬送され、搬送詰まりを起すおそれが少ないものとなる。   Since the open space Q is formed between the wrapping prevention cover 68 and the frame body 56 in this way, the long chopped cereal culm is sandwiched between the endless rotating chain 48 and the drive sprocket 46 and rotated together. However, even if it moves to the moving path on the upper side and the pinching is released and the harvested cereals fall down, the harvested cereals are positioned below the endless rotating chain 48 through the open space Q. Since it falls to the linear movement path | route K which carries out, it will be conveyed back with other cutting grain pestle, and there will be little possibility of causing conveyance clogging.
