【０００５】
即ち、刈取装置１０の脱穀装置４側の外側に沿うナロ−ガイド３４をへ字状に成形して該ナロ−ガイド３４の前端部を分草体１５の後側のソケット３７に回動自在に嵌合する一方該ナロ−ガイド３４の前部には螺杆形態の調節杆４０を連結し、該調節杆４０の外周に嵌合するボス４８に調節杆４０の螺旋溝４６に係合する案内子４７を設けて、該ボス４８を揺動ブラケット４４に取付けた電動モ−タＭ１の駆動で往復回転することによって調節杆４０を出し入れしてナロ−ガイド３４を出し入れすることができるように構成し、前記揺動ブラケット４４を回動ブラケット５１に対して左右揺動自在に設けると共に該揺動ブラケット４４の左右両側端部と回動ブラケット５１との間にばね５０，５０を介在させて構成し、前記回動ブラケット５１を刈取装置１０に対して上下方向の軸回りに回動自在に支持して前記調節杆４０の出入りを円滑に行わせるように構成し、前記揺動ブラケット４４に固定の案内ピン５３を前記回動ブラケット５１の案内溝５４に嵌合させて揺動ブラケット４４の揺動方向を調節杆４０の出入り方向に規制し、操作スイッチ５５，５６の操作によって前記電動モータＭ１を正逆回転させて調節杆４０を出し入れさせるように構成し、前記回動ブラケット５１に前記電動モ−タＭ１用の制御スイッチＳ１，Ｓ２，Ｓ３を設け、前記ばね５０，５０によって中立位置に保持される揺動ブラケット４４がナロ−ガイド３４に作用する一定力以上の外力によって押し込まれるときには、前記第一の制御スイッチＳ１がＯＮして電動モ−タＭ１を逆回転して調節杆４０を前記ナロ−ガイド３４に作用する外力と同方向へ移動させて揺動ブラケット４４を中立位置に保つに至らせ、更にそれ以上にナロ−ガイド３４が同方向へ押し込まれると前記第三の制御スイッチＳ３が押されて電動モ−タＭ１の駆動が停止するように構成する一方、ナロ−ガイド３４が押し込まれた状態から外側へ引かれるときには、前記揺動ブラケット４４の揺動によって逆側の前記第二の制御スイッチＳ２がＯＮして電動モ−タＭ１が正回転して調節杆４０及びナローガイド３４を外側方向へ押出すように構成したことを特徴とするコンバインのナロ−ガイドの構成とする。
【０００６】
操作スイッチ５５をＯＮするとモータＭ１は正回転されて調節杆４０を矢印Ａ方向へ押出して、隣接の穀稈を押し分けたり、畦際に沿って摺動する。又、別の操作スイッチ５６をＯＮするとモータＭ１の逆回転によって矢印Ｂ方向へ引込まれる。このようにして矢印Ａ方へ押出された状態で、ナローガイド３４が穀稈や畦際等に接することにより、揺動ブラケット４４が反矢印Ｂ方向へ押返されると、第一の制御スイッチＳ１がＯＮされて電動モ−タＭ１を逆転駆動して調節杆４０を中立位置になるまで矢印Ｂ方向へ引き込む。このとき更に畦際に対する押圧によりナローガイド３４の矢印Ｂ方向への押込み力が強くなると第三の制御スイッチＳ３が押されて、電動モータＭ１の逆回転を一旦停止する。
【０００７】
又、ナローガイド３４が矢印Ｂ方向へ引き込まれた状態から、穀稈の絡み等によって外側Ａへ引かれるときは、揺動ブラケット５４も同方向Ａへ揺動されて、逆側の第二の制御スイッチＳ２がＯＮされて、電動モータＭ１が正回転されて、調節杆４０及びナローガイド３４を矢印Ａ方向へ中立位置まで押出す。
【０００８】
【発明の効果】
以上のように、この発明は、刈取装置１０の脱穀装置４側の外側に沿うナロ−ガイド３４をへ字状に成形して該ナロ−ガイド３４の前端部を分草体１５の後側のソケット３７に回動自在に嵌合する一方該ナロ−ガイド３４の前部には螺杆形態の調節杆４０を連結し、該調節杆４０の外周に嵌合するボス４８に調節杆４０の螺旋溝４６に係合する案内子４７を設けて該ボス４８を電動モ−タＭ１の駆動で往復回転することによって調節杆４０を出し入れしてナロ−ガイド３４を出し入れすることができるように構成することにより、電動モ−タＭ１を正回転させることによって調節杆４０の出摺動を円滑に行わせて該調節杆４０及びナロ−ガイド３４を押出して、隣接の穀稈を押し分けることができる。又、電動モ−タＭ１を逆回転させることによって調節杆４０の入り摺動を円滑に行わせて該調節杆４０及びナロ−ガイド３４を引込ませることができる。
【０００９】
また、ナローガイド３４が穀稈や畦際等に接することにより、揺動ブラケット４４が反矢印Ｂ方向へ押返されると、電動モ−タＭ１を逆転駆動して調節杆４０を中立位置になるまで矢印Ｂ方向へ引き込むことができる。このとき更に畦際に対する押圧によりナローガイド３４の矢印Ｂ方向への押込み力が強くなると電動モータＭ１の逆回転を一旦停止することができる。
【００１０】
又、ナローガイド３４が矢印Ｂ方向へ引き込まれた状態から、穀稈の絡み等によって外側Ａへ引かれるときは、電動モータＭ１が正回転されて、調節杆４０及びナローガイド３４を矢印Ａ方向へ中立位置まで押出すことができる。
【００１１】
【発明の実施の形態】
コンバインは、クローラ６を有する車体７上に脱穀装置４を搭載し、この側方に操縦台８や操縦席９等を配置し、前方に刈取装置１０を装着する。脱穀装置４は、扱胴を前後方向の扱胴軸回りに回転するように軸装した脱穀室と、この脱穀室の一側において前後方向に沿う穀稈移送口と、この穀稈移送口に沿って穀稈を挟扼移送するように張設されたフィードチエン１１と等を有し、刈取穀稈の搬送供給を受けて後方へ移送しながら穂先部を脱穀室内へ適宜深さに供給して脱穀するものである。
【００１２】
刈取装置１０は、車台７の前部上に支架されて上下回動自在の刈取フレーム１２を主体として、車体７との間に設けられる油圧伸縮されるリフトシリンダ１３によって昇降される。刈取装置１０は下部にバリカン形態の刈刃装置１４を設け、前方に分草体１５を設ける。穀稈引起装置１は、この分草体１５の後側において後方上部に立設せる引起ケース１６と、この引起ケース１６内に沿って張設される引起チエン１７、この引起チエン１７に対して起伏自在の引起ラグ２、及びこの引起ラグ２の起伏姿勢を案内させるラグガイド３，１８等から構成され、刈取前の穀稈を一定の姿勢に引起して刈取を整然と行わせるものである。
【００１３】
ラグガイド１８は、引起チエン１７の下半部にあって、引起ラグ２を引起ケース１６の一側の穀稈案内路側に突出させるように摺動案内する。ラグガイド３は、該ラグガイド１８に対して上下に伸縮自在で、引起チエン１７の張設方向に沿って設けられ、引起ラグ２の突出姿勢の上昇域を調節する。このラグガイド３の後側には一体のピン１９が設けられて、引起ケース１６の後方側に長孔から突出され、このピン１９と引起ケース１６上端部との間にばね２０を設け、常時ラグガイド３を上方へ伸ばす方向へ張発している。このピン１９には、該ばね２０に抗して下方へ引くことのできるワイヤー２１を連結し、このワイヤー２１を操作レバー２２に連結し、この操作レバー２２の扱深調節操作によって、ラグガイド３を伸縮調節することができる。
【００１４】
穀稈引起装置１の後側で刈刃装置１４上方には、各条の引起穀稈を掻込集送する掻込装置２３を設け、この掻込装置２３で掻込まれる穀稈を刈刃装置１４で刈取ることができる。
【００１５】
穀稈搬送装置５は、この掻込装置２３と前記フィードチエン１１部との間に亘って設けられ、株元側を挟持搬送するチエン２４と穂部側を係合搬送するラグチエン２５とからなり、終端側をヒンジ２６として前端側を上下に回動することにより、掻込装置２３で集送される刈取穀稈の受継位置を稈身方向に変えることができ、搬送してフィードチエン１１側へ送込むことができる。この穀稈搬送装置５の扱深さ調節は、刈取フレーム１２に枢支２７されるアーム２８で、この搬送装置５の搬送フレームと一体の支持突子２９を受けて、このアーム２８を前記操作レバー２２で操作することにより行うことができる。３０はレバーガイドで、操作レバー２２の調節位置を適当な調節位置で係止して、扱深調節位置を維持できる。又、この操作レバー２２は前記操縦席９から操作できるように設けられている。
【００１６】
該操作レバー２２による穀稈搬送装置５とラグガイド３との連動は、標準稈長の穀稈刈取位置に対して、短稈Ａ刈取時は、穀稈搬送装置５を下動調節し、これによってラグガイド３も下動しうるもので、逆に、長稈Ｂ刈取時は、上動調節しうるものである。これによって刈取穀稈は、脱穀装置４の脱穀室に対する穂先部の供給深さが短稈、長稈に拘らずほゞ一定になるようにすることができる。又、短稈時は引起ラグ２による穂先部の掻き過ぎをなくして脱粒を防止し、長稈時は穂首位置まで十分に掻き上げて稈身を起立させることができる。
【００１７】
要するに、刈取装置では穀稈引起装置１の引起ラグ２の上昇によって稈身を起立されて刈取作用を受け、この刈取集送される穀稈が穀稈搬送装置５で受継搬送されて脱穀装置４へ供給され脱穀される。刈取穀稈の長短によって脱穀装置４へ供給する扱深調節を行うときは、該穀稈搬送装置５を長稈側へ移動すると脱穀装置４への供給深さが浅くなるように調節され、又逆に短稈側へ移動すると深くなるように調節される。これによって長稈時でも短稈時でも脱穀装置４の扱深を一定にすることができる。
【００１８】
又、このような扱深調節と同時に、穀稈引起装置１では引起ラグ２の穀稈引起上昇域を決めるラグガイド３が上下に移動されて、引起高調節が連動して行われる。即ち、扱深調節が長稈に対応するように浅扱側へ調整されるときは、ラグガイド３が上方へ移動されて長稈に応ずるように引起ラグ２の引起姿勢を高く維持させる。又、扱深調節が短稈に対応するように深扱側へ調整されるときは、ラグガイド３が下動されて、短稈引起に適するようになり、短稈を穂先端まで掻上げないようにすることができる。
【００１９】
このように扱深調節と引起高調節とが連動して行われるために、調節操作が簡単であり、いずれか一方の調節を行って他方の調節を忘れるようなことがなく、的確な長稈、短稈対応の調節を行うことができる。
【００２０】
図３において、上例と異なる点は、前記扱深調節と引起高調節とを、操作レバー２２に代えて電動モータＭによって連動するものである。刈取フレーム１２又は車台７等に設けられるモータＭの往復回動によって、駆動アーム３１からロッド３２を介して前記枢支部２７回りのアーム２８を回動して、扱深調節を行わせる連動構成とし、この駆動アーム３１に前記ラグガイド３との間のワイヤー２１を連結して、引起高調節との連動を行うものである。ばね２０はラグガイド３を下動する方向へ張圧し、ワイヤー２１はこのばね２０に抗して上方へ引き上げることができる。又、このワイヤー２１とピン１９との間には緩衝用のばね３３を介在させている。
【００２１】
図４、図５において、上例と異なる点は、前記モータＭの駆動とばね２０とによって連動するもので、ラグガイド３の上動Ｂはこのばね２０によって行わせ、下動ＡをモータＭの駆動で行い、ラグガイド３を引き上げるためのばね２０力と、穀稈搬送装置５の調節のための駆動力とのバランスを図ることができ、モータＭにかかる負荷を小さくし、モータＭを小形化し、減速装置もなくすることができる。
【００２２】
図６〜図８において、上例と異なる点は、刈取装置１０の脱穀装置４側の外側に沿って上外に回動するナローガイド３４と、穀稈引起ケース１６の外側面に沿うカバー軸３５回りに左右へ回動されるサイドカバー３６とを連動するもので、ナローガイド３４を外側へ開いた分草状態で、サイドカバー３６を外側へ開いて、分草体１５及び引起ケース１６で分草される未刈稈の穂部側が刈取装置１０内の穀稈搬送装置５側へ倒れ込むのを防止する。
【００２３】
前記ナローガイド３４は、前端部を分草体１５の後側のソケット３７に回動自在に嵌合し、へ字状に成形し、後端部３８を伸縮自在にして、前記車体７の後端部に枢着３９している。このナローガイド３４の前部に回動自在に連結する調節杆４０を分草杆４１のソケット４２に摺動自在に挿通させて、この調節杆４０の伸縮によりナローガイド３４の起伏を切替乃至調節する。刈取装置１０の該ナローガイド３４側の外側面を覆うサイドカバー３６の下端部が、このナローガイド３４の前端部上に接近してリンク４３連結され、ナローガイド３４の内外へ起伏回動に連動して、サイドカバー３６も内外へ閉開回動するように構成している。
【００２４】
なお、サイドカバー３６をナローガイド３４と一体の構成とするもよい。
【００２５】
図９において、上例と異なる点は、ナローガイド３４の出し入れを電動モータＭ１によって行わせるもので、この出し入れを操作スイッチ５５，５６、コントローラＣＰＵ、及び制御スイッチＳ１〜Ｓ３によって行わせる構成としている。調節杆４０は周面に螺旋コイル４５を巻きつけた螺杆形態とし、この調節杆４０の外周に嵌合するボス４８には該螺旋コイル４５の螺旋溝４６に係合する案内子４７を設け、このボス４８を揺動ブラケット４４に取付けた電動モータＭ１の駆動でチエン４９を介して往復回転することにより、該調節杆４０を出しＡ入れＢすることができる。
【００２６】
この揺動ブラケット４４は、案内突子４７等によって螺旋溝４６に係合しているために、ナローガイド３４側から矢印Ａ，Ｂ方向へ移動されると一体的に揺動される。この揺動ブラケット４４は左右両側端面をばね５０を介在させて、回動ブラケット５１に対して左右揺動自在に設けられ、更にこの回動ブラケット５１は刈取装置１０の一部の部材５２に対して上下方向の軸５５回りに回動自在に支持され、調節杆４０の出入り摺動を円滑に行わせるように構成している。５３は揺動ブラケット４４に固定の案内ピンで、回動ブラケット５１の案内溝５４に嵌合させて、揺動ブラケット４４の揺動方向を出入り方向Ａ，Ｂに規制している。
【００２７】
この回動ブラケット５１には、前記モータＭ１のＯＮ，ＯＦＦを行う制御スイッチＳ１〜Ｓ３を設け、前記ばね５０によって中立位置に保持される揺動ブラケット４４がナローガイド３４の一定以上の外力によって押込まれるＢときは、スイッチＳ１をＯＮしてモータＭ１を逆回転して調節杆４０を同方向Ｂへ移動させて、揺動ブラケット４４が中立位置を保つに至るようになる。更にそれ以上にナローガイド３４が同方向Ｂへ移動されるとスイッチＳ３が押されてモータＭ１の駆動は停止される。
【００２８】
操作スイッチ５５をＯＮするとモータＭ１は正回転されて調節杆４０を矢印Ａ方向へ押出して、隣接の穀稈を押し分けたり、畦際に沿って摺動する。又、操作スイッチ５６をＯＮするとモータＭ１の逆回転によって矢印Ｂ方向へ引込まれる。このようにして矢印Ａ方へ押出された状態で、ナローガイド３４が穀稈や畦際等に接することにより、揺動ブラケットが反矢印Ｂ方向へ押返されると、制御スイッチＳ１がＯＮされてＭ１を逆転駆動して調節杆４０を中立位置になるまで矢印Ｂ方向へ引き込む。このとき更に畦際に対する押圧によりナローガイド３４の矢印Ｂ方向への押込み力が強くなると制御スイッチＳ３が押されて、モータＭ１の逆回転を一旦停止する。
【００２９】
又、ナローガイド３４が矢印Ｂ方向へ引き込まれた状態から、穀稈の絡み等によって外側Ａへ引かれるときは、揺動ブラケット４４も同方向Ａへ揺動されて、制御スイッチＳ２がＯＮされて、モータＭ１が正回転されて、調節杆４０及びナローガイド３４を矢印Ａ方向へ中立位置まで押出す。

And threshed. When adjusting the handling depth to be supplied to the threshing apparatus 4 by the length of the harvested grain culm, when the grain culm transport device 5 is moved to the long culm side, the supply depth to the threshing apparatus 4 is adjusted to be shallow, and Conversely, it is adjusted to become deeper when it moves to the short culm side. Thereby, the handling depth of the threshing apparatus 4 can be made constant regardless of whether the culm is long or short.
[0018]
Simultaneously with such adjustment of the handling depth, in the grain stalk raising device 1, the rug guide 3 for determining the grain stalk raising area of the raising rug 2 is moved up and down, and the raising height is adjusted in conjunction with the lag guide. That is, when the handling depth adjustment is adjusted to the shallow handling side so as to correspond to the long culm, the lug guide 3 is moved upward to maintain the raising posture of the raising lug 2 high so as to respond to the long culm. In addition, when the handling depth adjustment is adjusted to the deep handling side so as to correspond to the short culm, the rug guide 3 is moved down to be suitable for raising the short culm, and the short culm is not lifted up to the tip of the ear. You can do so.
[0019]
Since the depth adjustment and the raising height adjustment are performed in this way, the adjustment operation is simple, and one of the adjustments is performed without forgetting to adjust the other. In addition, adjustment for short culm can be performed.
[0020]
In FIG. 3, the difference from the above example is that the handling depth adjustment and the raising height adjustment are linked by an electric motor M instead of the operation lever 22. A reciprocating rotation of a motor M provided on the mowing frame 12 or the undercarriage 7 rotates the arm 28 around the pivot 27 from the drive arm 31 via the rod 32 to adjust the handling depth. The drive arm 31 is connected to the wire 21 between the drive arm 31 and the lug guide 3 so as to interlock with the raising height adjustment. The spring 20 tensions the lug guide 3 in the downward direction, and the wire 21 can be pulled upward against the spring 20. A buffer spring 33 is interposed between the wire 21 and the pin 19.
[0021]
4 and 5, the difference from the above example is that the driving of the motor M and the spring 20 are interlocked. The upward movement B of the lug guide 3 is performed by the spring 20, and the downward movement A is performed by the motor M. , The balance between the spring 20 force for pulling up the lag guide 3 and the driving force for adjusting the grain stalk conveying device 5 can be achieved, the load on the motor M can be reduced, and the motor M It is possible to reduce the size and eliminate the need for a reduction gear.
[0022]
6 to 8, the difference from the above example is that a narrow guide 34 that pivots upward and outward along the outside of the mowing device 10 on the threshing device 4 side, and a cover shaft that extends along the outer surface of the grain stem raising case 16. The side cover 36 is pivoted to the left and right around 35. The side cover 36 is opened to the outside while the narrow guide 34 is opened to the outside, and the weeds 15 and the raising case 16 separate the side cover 36 to the outside. The ear side of the uncut culm to be grassed is prevented from falling down to the grain culm transport device 5 side in the cutting device 10.
[0023]
The narrow guide 34 has a front end rotatably fitted in a socket 37 on the rear side of the weeding body 15, is formed in an L-shape, and a rear end 38 is expandable and contractable. It is pivotally attached 39 to the part. An adjusting rod 40 rotatably connected to a front portion of the narrow guide 34 is slidably inserted into a socket 42 of the weeding rod 41, and the expansion and contraction of the adjusting rod 40 switches or adjusts the undulation of the narrow guide 34. I do. The lower end of the side cover 36 that covers the outer surface of the reaper 10 on the side of the narrow guide 34 approaches the front end of the narrow guide 34 and is connected to the link 43, and is linked to the inward and outward rotation of the narrow guide 34. Thus, the side cover 36 is also configured to rotate inward and outward.
[0024]
Note that the side cover 36 may be integrated with the narrow guide 34.
[0025]
9 is different from the above example in that the narrow guide 34 is moved in and out by the electric motor M1, and the moving in and out is performed by the operation switches 55 and 56, the controller CPU, and the control switches S1 to S3. . The adjusting rod 40 has a spiral rod shape in which a spiral coil 45 is wound around the peripheral surface, and a boss 48 fitted on the outer periphery of the adjusting rod 40 is provided with a guide 47 for engaging with the spiral groove 46 of the spiral coil 45. The boss 48 is reciprocally rotated via the chain 49 by the drive of the electric motor M1 attached to the swing bracket 44, so that the adjusting rod 40 can be put out and put in A.
[0026]
Since the swing bracket 44 is engaged with the spiral groove 46 by the guide projection 47 and the like, the swing bracket 44 is integrally swinged when moved in the directions of the arrows A and B from the narrow guide 34 side. The swing bracket 44 is provided so as to be able to swing left and right with respect to the rotating bracket 51 with springs 50 interposed at both left and right end surfaces. The adjustment rod 40 is rotatably supported about a vertical shaft 55 so that the adjusting rod 40 can slide in and out smoothly. Reference numeral 53 denotes a guide pin fixed to the swing bracket 44, which is fitted in the guide groove 54 of the rotating bracket 51, and regulates the swing direction of the swing bracket 44 in the in and out directions A and B.
[0027]
The rotary bracket 51 is provided with control switches S1 to S3 for turning on and off the motor M1, and the swing bracket 44 held at the neutral position by the spring 50 is pushed by the external force of the narrow guide 34 beyond a certain level. At the time of turning B, the switch S1 is turned on to rotate the motor M1 in the reverse direction to move the adjusting rod 40 in the same direction B, so that the swing bracket 44 maintains the neutral position. When the narrow guide 34 is further moved in the same direction B, the switch S3 is pressed and the driving of the motor M1 is stopped.
[0028]
When the operation switch 55 is turned on, the motor M1 is rotated forward and pushes the adjusting rod 40 in the direction of arrow A to push adjacent grain stems apart or slide along the ridge. When the operation switch 56 is turned on, the motor M1 is pulled in the direction of arrow B by the reverse rotation of the motor M1. When the narrow bracket 34 is pushed back in the direction of the arrow B by the narrow guide 34 coming into contact with the grain culm or the ridge in the state of being pushed in the direction of the arrow A in this way, the control switch S1 is turned on. M1 is driven in the reverse direction to pull the adjusting rod 40 in the direction of arrow B until it reaches the neutral position. At this time, if the pushing force of the narrow guide 34 in the direction of the arrow B is further increased by the pushing against the ridge, the control switch S3 is pushed, and the reverse rotation of the motor M1 is temporarily stopped.
[0029]
Further, from the state in which narrow guide 34 is retracted in the arrow B direction, when pulled outward A by such entanglement culms are swinging brackets 4 4 be swung in the same direction A, the control switch S2 is ON Then, the motor M1 is rotated forward to push the adjusting rod 40 and the narrow guide 34 in the direction of arrow A to the neutral position.
