【発明の属する技術分野】
この発明は、穀稈を刈取りする刈取機と、刈取り穀稈を引継ぎ移送して脱穀する脱穀機のフィードチェンとは、走行装置の走行車速に連動して、油圧式無段変速装置で変速回転駆動すると共に、操作装置に設けた操作手段の操作で、同じ走行車速に対する刈取機と、フィードチェンとの回転数を増速、又は減速制御すべく設けた技術であり、コンバインの伝動装置として利用できる。
【0002】
【従来の技術】
コンバインで立毛穀稈の収穫作業は、このコンバインを穀稈の植付圃場を走行させるが、圃場の乾・湿田状態、穀稈の作柄、及び倒伏状態等により、主変速レバーを所定位置へ操作し、走行装置の走行車速を設定して、植付圃場を走行させ、走行車台の前方部に設けて、走行車速に関係なく、一定の回転数で刈取機は回転駆動され、この刈取機で立毛穀稈は刈取りされ、この刈取り穀稈は、この刈取機で後方上部へ移送される。走行車台の上側へ載置した脱穀機のフィードチェンは、走行車速に関係なく、一定の回転数で回転駆動され、刈取機で後方上部へ移送された穀稈は、このフィードチェンと、挟持杆とへ供給されて引継ぎされ、これらフィードチェンと、挟持杆とで挟持されて、脱穀機内を挟持移送中に脱穀され、脱穀済み穀粒は、穀粒貯留タンク内へ供給され、一時貯留される。
【0003】
前述の収穫作業中に、倒伏状態が変り、走行車速を主変速レバーを操作して変更したときでも、刈取機、及び脱穀機のフィードチェンの回転数は、一定の回転数で回転駆動され、穀稈の刈取り、及び脱穀が行われる。
そして、運転室内の切換スイッチを操作する事により、刈取前処理装置とフィードチェンの駆動をコンバインの車速に対して非同調制御するもので、この非同調制御は予め決められた一定速へ切り換える構成である(例えば、特許文献1参照。)。

【発明が解決しようとする課題】
走行装置の走行車速に関係なく、穀稈を刈取る刈取機、及び脱穀機のフィードチェンは、一定の回転数で回転駆動されることにより、特に走行車速が最高速、又は最低速で走行したときは、刈取機から脱穀機のフィードチェンへの穀稈の引継ぎが不良になることがあったり、負荷変動が大きくなること等があったが、この発明により、これらの問題点を解決しようとするものである。
【0006】
非同調制御が一定速なので、車速が低速の時に非同調制御に切り換えると、刈取前処理装置が速すぎて脱粒や搬送乱れを起こしていた。
【0007】
【課題を解決するための手段】
このために、この発明は、請求項1に記載の発明においては、穀稈を刈取り移送する刈取機3と、刈取り穀稈を引継ぎ移送する脱穀機4のフィードチェン5とを回転駆動する油圧式無段変速装置9と、走行装置7等とを設けたコンバインにおいて、該走行装置7の走行車速に連動して、刈取機3と、フィードチェン5とを油圧式無段変速装置9で変速回転駆動すると共に、運転操作する操作装置10に設けた操作手段11の操作で、同じ走行車速に対する刈取機3と、フィードチェン5との回転数を任意の速度に増速、又は減速制御する制御装置10bを設けたことを特徴とするコンバインの伝動装置としたものである。
【0008】
コンバインで立毛穀稈の収穫作業は、このコンバインを穀稈の植付圃場を走行させるが、圃場の乾・湿田状態、穀稈の作柄、及び倒伏状態等により、主変速レバー10aを所定位置へ操作し、走行装置7の走行車速を設定して、圃場を走行させ、走行車台の前方部に設けて、設定した走行車速に連動して、刈取機3は、所定の回転数に変更されて回転駆動され、この刈取機3で立毛穀稈は刈取りされ、この刈取り穀稈は、この刈取機3で後方上部へ移送される。走行車台の上側へ載置した脱穀機4のフィードチェン5は、設定した走行車速に連動して、所定の回転数に変更されて回転駆動され、刈取機3で後方上部へ移送された穀稈は、脱穀機4のフィードチェン5と、挟持杆とへ供給されて引継ぎされ、これらフィードチェン5と、挟持杆とで挟持されて、脱穀機4内を挟持移送中に脱穀され、脱穀済み穀粒は、穀粒貯留タンク内へ供給され、一時貯留される。
【0009】
又、この収穫作業のときに、操作装置10に設けた操作手段11を操作すると、走行装置7は、主変速レバー10aを所定位置へ操作した操作位置により、所定の走行速度で走行するが、この設定された走行速度に連動して、刈取機3と、脱穀機4との回転数は、変更制御されずに、操作手段11の操作位置により、これら刈取機3と、脱穀機4のフィードチェン5との回転数は、増速回転側、又は減速回転側へ変更制御され、設定された増速、又は減速の所定の回転数で、刈取機3は回転駆動され、穀稈は刈取り移送される。又、脱穀機4のフィードチェン5も所定の回転数で、回転駆動されて、このフィードチェン5と、挟持杆とで挟持移送される穀稈は、脱穀機4で脱穀される。
【0010】
請求項2に記載の発明においては、前記操作手段11は、走行車速を設定操作する主変速レバー10aへ設けたことを特徴とする請求項1に記載のコンバインの伝動装置としたものである。
前記主変速レバー10aを所定位置へ操作して、走行装置7の走行速度を設定し、この設定した走行速度に連動させないで、刈取機3と、脱穀機4のフィードチェン5とを、所定の回転数で回転駆動させるときは、操作装置10の主変速レバー10aに設けた操作手段11を増速回転側、又は減速回転側へ操作して、刈取機3と、脱穀機4のフィードチェン5との回転数を増速回転数駆動、又は減速回転数駆動させて、刈取り収穫作業を行う。
【0011】
【発明の効果】
請求項1に記載の発明においては、走行装置7の走行車速は、主変速レバー10aの操作により、所定の走行車速が設定され、この設定された走行車速に連動して、穀稈を刈取り移送する刈取機3と、穀稈を脱穀する脱穀機4のフィードチェン5との回転数は、変速回転制御される。又、操作手段11の操作で、同じ走行車速に対する刈取機3と、脱穀機4のフィードチェン5との回転数を増速回転数、又は減速回転数に制御する構成としたことにより、走行車速に連動して、刈取機3と、脱穀機4のフィードチェン5とが、変速回転されるので、この刈取機3から脱穀機4のフィードチェン5への穀稈の引継ぎが良好になる。又、走行車速に対して、例えば、穀稈の倒伏がひどいとき等には、操作手段11の操作により、刈取機3と、フィードチェン5との回転速度を増速させて、穀稈を速やかに引起し、及び刈取り移送し、脱穀機4へ速く引継ぎ、この脱穀機4内を速く移送して脱穀ができる。又、負荷の変動を減少させることができる。
【0012】
請求項2に記載の発明においては、走行車速を設定する前記主変速レバー10aには、操作手段11を設けたことにより、走行車速を変更しながら、容易に該操作手段11の操作ができる。又操作が便利である。更に操作性の向上を図ることができる。

The threshing machine 4 moves the upper surface of the traveling platform 2 in the front-rear direction by the expansion and contraction operation of the front and rear cylinders 40, thereby maintaining the engine 20, the transmission case 8, the vehicle body horizontal ring of the traveling device 7, and the cylinders. Is easy.
As shown in FIGS. 12 and 13, an inner transmission shaft 41 is provided on the support pipe rod 18 b of the reaper 3 as an inner support shaft, and an inner coupling 41 a is provided at an outer end of the inner transmission shaft 41. A pivot shaft 42 is formed integrally with the support pipe rod 18b at the right end of the support pipe rod 18b. The rotation shaft 42 is inserted into the right rotation support metal 43a and is rotatably supported.
[0042]
The left outer end of the support pipe rod 18b and the outer support metal 44 are configured to be supported by a left support metal 43b. One end of the tip of the left support metal 43b rotatably supports the support pipe rod 18b, and a left metal 44 is provided on the other side of the tip.
[0043]
An external power transmission shaft 44a is provided on the left metal 44 so as to support the internal shaft. The rotational power of the engine 20 is input to the outer end of the external power transmission shaft 44a, and each part of the reaper 3 is rotationally driven. The input pulley 44b is pivotally provided, and an outer coupling 44c is pivotally provided at the inner end. The outer coupling 44c and the inner coupling 41a are configured to mesh with one touch.
[0044]
When the reaper 3 is rotated rightward and outward as shown in FIG. 12, the inner and outer couplings 41a and 44c are disengaged from each other, and the rotation axis of the support pipe rod 18b inserted into the right rotation support metal 43a. The reaper 3 is configured to rotate to the right outside as the center of rotation of 42.
[0045]
Accordingly, when the reaper 3 is rotated outward, it is not necessary to remove the belt 44d that is stretched over the input pulley 44b, and the reaper 3 is easily rotated.
A front-rear cylinder 45 for moving the reaper 3 in the front-rear direction is provided as shown in FIG. 14, and below the right turning support metal 43 a and the left support metal 43 b of the reaper 3 is shown in FIG. 15. In this manner, each wheel 3a is rotatably supported.
[0046]
As shown in FIG. 14, the wheels 3a are configured to rotate back and forth on the upper surface of each support frame 2a provided on the traveling chassis 2 by the expansion and contraction operation of the front and rear cylinders 45. It is a configuration that moves back and forth. Each of the support frames 2a has a configuration in which support plates 2b are provided on both left and right sides. Also, as shown in FIGS. 12 and 13, the reaper 3 is configured to be rotatable to the right outside.
[0047]
Accordingly, the reaper 3 is moved forward, so that interference with the feed chain 5 of the threshing machine 4 is eliminated, and the reaper 3 can be easily turned to the right outside. Further, by moving forward, even if the opening / closing angle is small, the space becomes large, and therefore, the opening / closing angle can be reduced, and the weight and size of the support member can be reduced.
