図1,2に示すように、コンバインは、機体フレーム1の下側に土壌面を走行する左右一対のクローラからなる走行装置2が設けられ、機体フレーム1の前側に圃場の穀稈を刈取る刈取装置3が設けられ、刈取装置3の後方左側に刈取られた穀稈を脱穀・選別処理する脱穀装置4が設けられ、刈取装置3の後方右側に作業者が搭乗する操縦部5が設けられている。 As shown in Figures 1 and 2, the combine harvester has a traveling device 2 consisting of a pair of left and right crawlers that travel on the soil surface on the underside of the machine frame 1, a harvesting device 3 that harvests the stalks in the field is provided on the front side of the machine frame 1, a threshing device 4 that threshes and sorts the harvested stalks is provided on the rear left side of the harvesting device 3, and a control unit 5 on which the operator rides is provided on the rear right side of the harvesting device 3.

操縦部5の下側には、エンジンを搭載するエンジンルーム6が設けられ、操縦部5の後側には、脱穀・選別処理された穀粒を貯留するグレンタンク7が設けられ、グレンタンク7の後側には、穀粒を外部に排出する上下方向に延在する揚穀部と前後方向に延在する横排出からなる排出オーガ8が設けられている。 Below the control unit 5 is an engine room 6 that houses the engine, and behind the control unit 5 is a grain tank 7 that stores the threshed and sorted grains, and behind the grain tank 7 is a discharge auger 8 that consists of a vertically extending grain lifting section that discharges the grains to the outside and a horizontal discharge section that extends back and forth.

刈取装置3の刈取フレーム10は、エンジンの出力回転が伝動される左右方向に延在する伝動筒11と、伝動筒11の右部から前側に向かって延在する伝動筒12と、伝動筒12の下部から左右方向に延在する伝動筒13と、伝動筒13の左部から上側に向かって延在する伝動筒14と、伝動筒14の上部から左右方向に延在する伝動筒15から形成されている。 The harvesting frame 10 of the harvesting device 3 is formed from a transmission tube 11 extending in the left-right direction to transmit the output rotation of the engine, a transmission tube 12 extending forward from the right part of the transmission tube 11, a transmission tube 13 extending in the left-right direction from the lower part of the transmission tube 12, a transmission tube 14 extending upward from the left part of the transmission tube 13, and a transmission tube 15 extending in the left-right direction from the upper part of the transmission tube 14.

刈取フレーム10には、圃場に植立する穀稈を分草する分草体16と、分草された穀稈を引起こす引起装置17と、引起こされた穀稈の株元を切断する刈刃装置18と、刈取られた穀稈を挟持して脱穀装置4に搬送する搬送装置19が装着されている。 The harvesting frame 10 is equipped with a harvesting body 16 that harvests the culms planted in the field, a lifting device 17 that raises the harvested culms, a cutting blade device 18 that cuts the base of the raised culms, and a transport device 19 that clamps the harvested culms and transports them to the threshing device 4.

図3,4に示すように、伝動筒11の右部と伝動筒15の中間部は、丸鋼からなる連結部材20で連結され、伝動筒15の右部と伝動筒13の右部は、丸鋼からなる連結部材21で連結されている。これにより、伝動筒15の左部を伝動筒14で支持し、伝動筒15の中間部を連結部材20で支持し、伝動筒15の右部を連結部材21で支持するので、伝動筒15の撓みや捻じり等の変形を抑制することができる。 As shown in Figures 3 and 4, the right part of the transmission tube 11 and the middle part of the transmission tube 15 are connected by a connecting member 20 made of round steel, and the right part of the transmission tube 15 and the right part of the transmission tube 13 are connected by a connecting member 21 made of round steel. As a result, the left part of the transmission tube 15 is supported by the transmission tube 14, the middle part of the transmission tube 15 is supported by the connecting member 20, and the right part of the transmission tube 15 is supported by the connecting member 21, so deformation of the transmission tube 15, such as bending or twisting, can be suppressed.

連結部材20は、搬送装置19の上側を超えるように、伝動筒11の右部から前方上側に向かって延在した後に、前側に向かって延在し、その後、前方下側に向かって延在して伝動筒15に至っている。また、連結部材21は、搬送装置19の上側を超えるように、伝動筒13の右部から前方上側に向かって延在した後に、上側に向かって延在し、その後、前方上側に向かって延在して伝動筒15に至っている。 The connecting member 20 extends from the right side of the transmission tube 11 toward the upper front side so as to pass over the upper side of the conveying device 19, then extends toward the front side, and then extends toward the lower front side to reach the transmission tube 15. The connecting member 21 extends from the right side of the transmission tube 13 toward the upper front side so as to pass over the upper side of the conveying device 19, then extends toward the upper side, and then extends toward the upper front side to reach the transmission tube 15.

図5に示すように、分草体16は、5個の分草体16A~16Eから形成されている。
分草体16A~16Eは、伝動筒13から前側に向かって延在し、左右方向に所定の間隔を隔てて設けられた前後フレーム22の前部に固定されている。また、最も左側に設けられた前後フレーム22と最も右側に設けられた前後フレーム22の中間部を連結する丸パイプで形成されたフレーム23で連結されている。
As shown in FIG. 5, the plant segment 16 is formed from five plant segments 16A to 16E.
The grass segments 16A to 16E extend forward from the transmission tube 13 and are fixed to the front of the front-rear frames 22 that are spaced apart from each other in the left-right direction. The grass segments 16A to 16E are connected to each other by a frame 23 made of a round pipe that connects the middle parts of the front-rear frames 22 on the leftmost side and the front-rear frames 22 on the rightmost side.

引起装置17は、4個の引起装置17A~17Dから形成されている。引起装置17Bの引起こし反対側の右部と引起装置17Cの引起こし反対側の左部を対向して配置している。これにより、引起装置17A,17Bの間で2条、引起装置17C,17Dの間で2条の計4条の穀稈を同時に引起こすことができる。 The lifting device 17 is made up of four lifting devices 17A to 17D. The right side of lifting device 17B and the left side of lifting device 17C are arranged opposite each other. This allows a total of four rows of stumps to be lifted simultaneously: two rows between lifting devices 17A and 17B, and two rows between lifting devices 17C and 17D.

図6~8に示すように、引起装置17Aの上部に設けられた駆動スプロケットを支持する支軸(図示省略)は、伝動筒15の左部から下側に向かって延在する上下伝動筒30Lの回転軸31Lに連結され、引起装置17Aの下部は、フレーム23の左部から上方右側に湾曲するステー32Lに設けられた矩形状の連結部材33Lに固定されている。これにより、伝動筒15に内装された回転軸に伝動されたエンジンの出力回転は、上下伝動筒30Lに内装された回転軸を介して引起装置17Aの駆動スプロケットに伝動されて引起チェンを回動することができる。また、伝動筒15の前側にはカバー25が設けられている。 As shown in Figures 6 to 8, a support shaft (not shown) supporting a drive sprocket provided at the top of the lifting device 17A is connected to a rotating shaft 31L of the upper and lower transmission cylinders 30L that extends downward from the left side of the transmission cylinder 15, and the lower part of the lifting device 17A is fixed to a rectangular connecting member 33L provided on a stay 32L that curves upward and to the right from the left side of the frame 23. As a result, the output rotation of the engine transmitted to the rotating shaft installed inside the transmission cylinder 15 is transmitted to the driving sprocket of the lifting device 17A via the rotating shaft installed inside the upper and lower transmission cylinders 30L, and the lifting chain can be rotated. In addition, a cover 25 is provided on the front side of the transmission cylinder 15.

引起装置17Dの上部に設けられた駆動スプロケットを支持する支軸(図示省略)は、伝動筒15の右部から下側に向かって延在する上下伝動筒30Rの回転軸31Rに連結され、引起装置17Dの下部は、フレーム23の右部から上方左側に湾曲するステー32Rに設けられた矩形状の連結部材33Rに固定されている。これにより、伝動筒15に内装された回転軸に伝動されたエンジンの出力回転は、上下伝動筒30Rに内装された回転軸を介して引起装置17Dの駆動スプロケットに伝動されて引起チェンを回動することができる。 The shaft (not shown) supporting the drive sprocket provided at the top of the lifting device 17D is connected to the rotating shaft 31R of the upper and lower transmission tubes 30R that extends downward from the right side of the transmission tube 15, and the lower part of the lifting device 17D is fixed to a rectangular connecting member 33R provided on a stay 32R that curves upward and to the left from the right side of the frame 23. As a result, the output rotation of the engine transmitted to the rotating shaft installed inside the transmission tube 15 is transmitted to the driving sprocket of the lifting device 17D via the rotating shaft installed inside the upper and lower transmission tubes 30R, and the lifting chain can be rotated.

伝動筒15の左右方向の中間部には、中間部から下側に向かって延在する上下伝動筒41が設けられ、上下伝動筒41の下部には、左右方向に延在する左右伝動筒42が設けられている。また、フレーム23の中間部には、中間部から上側に向かって延在するステー43が設けられ、ステー43の上部には丸パイプから形成された左右方向に延在する左右フレーム44が設けられている。 In the middle of the transmission tube 15 in the left-right direction, an upper and lower transmission tube 41 is provided, which extends downward from the middle part, and a left-right transmission tube 42 is provided below the upper part of the upper and lower transmission tube 41, which extends in the left-right direction. In addition, in the middle part of the frame 23, a stay 43 is provided, which extends upward from the middle part, and a left-right frame 44 made of a round pipe is provided above the stay 43, which extends in the left-right direction.

左右フレーム44の両側部にはワッシャ等からなる規制部材44L,44Rが設けられている。これにより、後述する左挟持部品48Lと右挟持部品48Rが左右フレーム44から左右方向に外れるのを防止することができる。 Restricting members 44L, 44R made of washers or the like are provided on both sides of the left and right frames 44. This prevents the left clamping part 48L and the right clamping part 48R, which will be described later, from coming off the left and right frames 44 in the left-right direction.

左右伝動筒42と左右フレーム44の左部は、左上下フレーム45Lで連結され、左右伝動筒42と左右フレーム44の右部は、右上下フレーム45Rで連結されている。これにより、左右伝動筒42と左右フレーム44の剛性を高めることができ、引起装置17B,17Cを取外した場合においても左右伝動筒42と左右フレーム44の変形を抑制することができる。なお、背面視において、上下伝動筒41、左右伝動筒42、ステー43、左右フレーム44、左上下フレーム45L、及び右上下フレーム45Rは、引起装置17B,17Cの外周部よりも内側に配置されている。 The left parts of the left and right transmission tubes 42 and the left and right frames 44 are connected by the left upper and lower frames 45L, and the right parts of the left and right transmission tubes 42 and the left and right frames 44 are connected by the right upper and lower frames 45R. This increases the rigidity of the left and right transmission tubes 42 and the left and right frames 44, and prevents deformation of the left and right transmission tubes 42 and the left and right frames 44 even when the lifting devices 17B and 17C are removed. In addition, when viewed from behind, the upper and lower transmission tubes 41, the left and right transmission tubes 42, the stays 43, the left and right frames 44, the left upper and lower frames 45L, and the right upper and lower frames 45R are positioned inside the outer periphery of the lifting devices 17B and 17C.

引起装置17Bの上部に設けられた駆動スプロケット50を支持する回転軸51は、左右伝動筒42の回転軸46Lに連結され、引起装置17Bの上部における回転軸46Lに対向する部位に近接する部位は、スナップ錠等の左係合部品47Lを介して左右伝動筒42の左部に固定され、引起装置17Bの下部は、スナップ錠等の左挟持部品48Lを介して左右フレーム44の左部に固定されている。これにより、伝動筒15に内装された回転軸に伝動されたエンジンの出力回転は、上下伝動筒41と左右伝動筒42に内装された回転軸を介して引起装置17Bの駆動スプロケット50に伝動されて引起チェンを回動することができる。 The rotating shaft 51 supporting the drive sprocket 50 provided at the top of the lifting device 17B is connected to the rotating shaft 46L of the left and right transmission tubes 42, and the part of the upper part of the lifting device 17B adjacent to the part facing the rotating shaft 46L is fixed to the left part of the left and right transmission tubes 42 via a left engaging part 47L such as a snap lock, and the lower part of the lifting device 17B is fixed to the left part of the left and right frames 44 via a left clamping part 48L such as a snap lock. As a result, the output rotation of the engine transmitted to the rotating shaft installed inside the transmission tube 15 is transmitted to the driving sprocket 50 of the lifting device 17B via the rotating shafts installed inside the upper and lower transmission tubes 41 and the left and right transmission tubes 42, and the lifting chain can be rotated.

引起装置17Cの上部に設けられた駆動スプロケット(図示省略)を支持する回転軸(図示省略)は、左右伝動筒42の回転軸46Rに連結され、引起装置17Cの上部における回転軸46Rに対向する部位に近接する部位は、スナップ錠等の右係合部品47Rを介して左右伝動筒42の右部に固定され、引起装置17Cの下部は、スナップ錠等の右挟持部品48Rを介して左右フレーム44の右部に固定されている。これにより、伝動筒15に内装された回転軸に伝動されたエンジンの出力回転は、上下伝動筒41と左右伝動筒42に内装された回転軸を介して引起装置17Cの駆動スプロケットに伝動されて引起チェンを回動することができる。 The rotating shaft (not shown) supporting the drive sprocket (not shown) provided at the top of the lifting device 17C is connected to the rotating shaft 46R of the left and right transmission tubes 42, and the part of the upper part of the lifting device 17C adjacent to the part facing the rotating shaft 46R is fixed to the right part of the left and right transmission tubes 42 via a right engaging part 47R such as a snap lock, and the lower part of the lifting device 17C is fixed to the right part of the left and right frames 44 via a right clamping part 48R such as a snap lock. As a result, the output rotation of the engine transmitted to the rotating shaft installed inside the transmission tube 15 is transmitted to the driving sprocket of the lifting device 17C via the rotating shafts installed inside the upper and lower transmission tubes 41 and the left and right transmission tubes 42, and the lifting chain can be rotated.

左上下フレーム45Lの上部には、引起装置17Bの引起チェン(図示省略)にオイルを注油する注油ノズルを支持する支持部材49Lが設けられ、右上下フレーム45Rの上部には、引起装置17Cの引起チェン(図示省略)にオイルを注油する注油ノズルを支持する支持部材49Lが設けられている。なお、引起チェンには所定の間隔を隔てて引起ラグ35が装着されている。 A support member 49L is provided on the top of the left upper and lower frames 45L to support an oil nozzle that injects oil into the lifting chain (not shown) of the lifting device 17B, and a support member 49L is provided on the top of the right lower frame 45R to support an oil nozzle that injects oil into the lifting chain (not shown) of the lifting device 17C. In addition, lifting lugs 35 are attached to the lifting chain at a specified interval.

図9に示すように、上下伝動筒41の前部に設けられた係合部材52から前方下側に向かって延在する吊下フレーム24の下部は、分草体16Cの後部に設けられた左右方向に延在するピン53に回転自在に支持されている。これにより、図10に示すように、吊下フレーム24の上部と係合部材52の係合を解除して、ピン53の軸心回りに吊下フレーム24の上部を前側に引き出して引起装置17Bと引起装置17Cの着脱を容易に行うことができる。 As shown in Figure 9, the lower part of the hanging frame 24, which extends downward and forward from the engagement member 52 provided at the front of the upper and lower transmission tubes 41, is rotatably supported by a pin 53 extending in the left-right direction provided at the rear of the grass division body 16C. This makes it possible to easily attach and detach the lifting device 17B and the lifting device 17C by releasing the engagement between the upper part of the hanging frame 24 and the engagement member 52 and pulling the upper part of the hanging frame 24 forward around the axis of the pin 53, as shown in Figure 10.

図9に示すように、引起装置17Bの後面における上部、すなわち、駆動スプロケット50よりも下側の部位は、左係合部品47Lを介して左右伝動筒42の左部に固定され、引起装置17Bの後面における下部は、左挟持部品48Lを介して左右フレーム44の左部に固定されている。 As shown in FIG. 9, the upper part of the rear surface of the lifting device 17B, i.e., the part below the drive sprocket 50, is fixed to the left part of the left/right transmission cylinder 42 via the left engagement part 47L, and the lower part of the rear surface of the lifting device 17B is fixed to the left part of the left/right frame 44 via the left clamping part 48L.

引起装置17Bを左右伝動筒42等から取外す場合には、先ず、図11に示すように、引起装置17Bの回転軸51と左右伝動筒42の回転軸46Lの連結を解除し、引起装置17Bの後面の上部と左係合部品47Lの係合を解除して、左右フレーム44の軸心回りに引起装置17Bの上部を前側に引き出す。次に、図12に示すように、引起装置17Bの下部と左挟持部品48Lの係合を解除して、引起装置17Bの下部を左右フレーム44の左部から取り外す。これにより、引起装置17Bを左右伝動筒42等から取外して引起装置17Bの後側に配置された搬送装置19に絡み付いた穀稈を容易に取除くことができる。 When removing the lifting device 17B from the left and right transmission tubes 42, first, as shown in FIG. 11, the rotation shaft 51 of the lifting device 17B is disconnected from the rotation shaft 46L of the left and right transmission tubes 42, the upper part of the rear surface of the lifting device 17B is disengaged from the left engagement part 47L, and the upper part of the lifting device 17B is pulled forward around the axis of the left and right frames 44. Next, as shown in FIG. 12, the lower part of the lifting device 17B is disengaged from the left clamping part 48L, and the lower part of the lifting device 17B is removed from the left part of the left and right frames 44. This makes it possible to easily remove the straw entangled in the conveying device 19 arranged behind the lifting device 17B by removing the lifting device 17B from the left and right transmission tubes 42, etc.

左上下フレーム45Lは、引起装置17Bの後面と平行に設けられている。これにより、左右伝動筒42と左右フレーム44の左部の剛性をより高めることができる。 The left upper and lower frames 45L are arranged parallel to the rear surface of the lifting device 17B. This increases the rigidity of the left and right transmission tubes 42 and the left and right frames 44.

同様に、引起装置17Cの後面における上部、すなわち、駆動スプロケット(図示省略)よりも下側の部位は、右係合部品47Rを介して左右伝動筒42の右部に固定され、引起装置17Cの後面における下部は、左挟持部品48Lを介して左右フレーム44の右部に固定されている。 Similarly, the upper part of the rear surface of the lifting device 17C, i.e., the part below the drive sprocket (not shown), is fixed to the right part of the left and right transmission cylinders 42 via the right engagement part 47R, and the lower part of the rear surface of the lifting device 17C is fixed to the right part of the left and right frames 44 via the left clamping part 48L.

引起装置17Cを左右伝動筒42等から取外す場合には、引起装置17Bと同様に、引起装置17Cの回転軸(図示省略)と左右伝動筒42の回転軸46Rの連結を解除し、引起装置17Cの後面の上部と右係合部品47Rの係合を解除して、左右フレーム44の軸心回りに引起装置17Cの上部を前側に引き出す。次に、引起装置17Cの下部と右挟持部品48Rの係合を解除して、引起装置17Cの下部を左右フレーム44の右部から取り外す。これにより、引起装置17Cを左右伝動筒42等から取外して引起装置17Cの後側に配置された搬送装置19に絡み付いた穀稈を容易に取除くことができる。 When removing the lifting device 17C from the left and right transmission tubes 42, etc., the lifting device 17C's rotating shaft (not shown) is disconnected from the left and right transmission tubes 42's rotating shaft 46R in the same manner as the lifting device 17B, the upper part of the rear surface of the lifting device 17C is disengaged from the right engagement part 47R, and the upper part of the lifting device 17C is pulled forward around the axis of the left and right frames 44. Next, the lower part of the lifting device 17C is disengaged from the right clamping part 48R, and the lower part of the lifting device 17C is removed from the right part of the left and right frames 44. This makes it possible to easily remove the straw entangled in the conveying device 19 arranged behind the lifting device 17C by removing the lifting device 17C from the left and right transmission tubes 42, etc.

右上下フレーム45Rは、引起装置17Cの後面と平行に設けられている。これにより、左右伝動筒42と左右フレーム44の右部の剛性をより高めることができる。 The upper right and lower right frames 45R are arranged parallel to the rear surface of the lifting device 17C. This increases the rigidity of the left and right transmission tubes 42 and the right parts of the left and right frames 44.

図13,14に示すように、左係合部品47Lは、左右伝動筒42の左部に設けられた係合部60と、引起装置17Bの後面に設けられた被係合部(請求項における「第1被係合部」)61から形成されている。係合部60は、取付プレート60Aと、取付プレート60Aに設けられた上下方向に延在するピン60Bと、ピン60Bに回転自在に装着されたレバー60Cと、レバー60Cに設けられたフック60Dから形成されている。なお、被係合部61は、引起装置17Bの後面から後側に向けて延在し、被係合部61の右部には、フック60Dが係合する凹凸が形成されている。これにより、引起装置17Bの上部を、左右伝動筒42の左部に容易に固定したり、左右伝動筒42の左部から取外すことができる。 13 and 14, the left engaging part 47L is formed of an engaging part 60 provided on the left part of the left-right transmission tube 42 and an engaged part (the "first engaged part" in the claims) 61 provided on the rear surface of the lifting device 17B.

The engaged part 61 extends rearward from the rear surface of the lifting device 17B, and the right part of the engaged part 61 is formed with a projection and recess for engaging with the hook 60D. This allows the upper part of the lifting device 17B to be easily fixed to the left part of the left-right transmission tube 42 or removed from the left part of the left-right transmission tube 42.

同様に、右係合部品47Rは、左右伝動筒42の右部に設けられた係合部60と、引起装置17Cの後面に設けられた被係合部61から形成されている。係合部60は、取付プレート60Aと、取付プレート60Aに設けられた上下方向に延在するピン60Bと、ピン60Bに回転自在に装着されたレバー60Cと、レバー60Cに設けられたフック60Dから形成されている。なお、被係合部61は、引起装置17Cの後面から後側に向けて延在し、被係合部61の左部には、フック60Dが係合する凹凸が形成されている。これにより、引起装置17Cの上部を、左右伝動筒42の右部に容易に固定したり、左右伝動筒42の右部から取外すことができる。 Similarly, the right engaging part 47R is formed from an engaging part 60 provided on the right part of the left-right transmission cylinder 42 and an engaged part 61 provided on the rear surface of the lifting device 17C. The engaging part 60 is formed from a mounting plate 60A, a pin 60B extending in the vertical direction provided on the mounting plate 60A, a lever 60C rotatably attached to the pin 60B, and a hook 60D provided on the lever 60C. The engaged part 61 extends rearward from the rear surface of the lifting device 17C, and the left part of the engaged part 61 is formed with an uneven surface with which the hook 60D engages. This allows the upper part of the lifting device 17C to be easily fixed to the right part of the left-right transmission cylinder 42 or removed from the right part of the left-right transmission cylinder 42.

図15,16に示すように、左挟持部品48Lは、引起装置17Bの後面の下部に設けられた上挟持部65と、上挟持部65の下側に設けられた下挟持部66から形成されている。 As shown in Figures 15 and 16, the left clamping part 48L is formed of an upper clamping part 65 provided on the lower part of the rear surface of the lifting device 17B and a lower clamping part 66 provided below the upper clamping part 65.
