【発明の属する技術分野】
この発明は、穀粒を移送する固定移送螺旋を内装した固定用移送筒の外周部へ挿入して伸縮装置で伸縮自在な複数の移動用移送螺旋を内装した移動用移送筒を設け、該移動用移送筒の収縮位置を検出する収納センサは、これら固定用移送筒と移動用移送筒との重合部を支持する支持装置に設けると共に、該固定用移送筒へ該移動用移送筒を最短縮状態に重合移動させるときは、制御装置により、該移動用移送筒を該固定用移送筒の基部から所定距離の間は重合させないよう移動制御する技術であり、コンバインの伸縮穀粒移送装置として利用できる。
【０００２】
【従来の技術】
例えば、コンバインで立毛穀稈を収穫作業のときは、このコンバインの刈取機で刈取りした刈取り穀稈は、脱穀機へ供給されて脱穀され、脱穀済み穀粒は穀粒貯留タンクへ供給されて一時貯留される。この貯留した穀粒は縦移送筒から伸縮穀粒移送装置の固定用移送筒に内装した固定移送螺旋と、この固定用移送筒の外周部へ挿入して、伸縮装置で伸縮自在な移動用移送筒は、該伸縮装置により、所定長さ位置まで重合状態に伸張移動され、又、所定位置へ回動移動されて、この移動用移送筒に内装した複数の移動用移送螺旋とによって機外へ排出される。
【０００３】
この穀粒の排出が終了して次に収穫する圃場へ圃場内を走行移動するとき、及び路上走行のとき等は、前記移動用移送筒が固定用移送筒の基部まで完全に重合状態になる元の最短縮位置へ伸縮装置で重合状態に移動されると共に、元の位置へ回動移動され、これら移動用移送筒と固定用移送筒との重合部を、支持装置で支持させた後に移動走行させる。
【０００４】
【発明が解決しようとする課題】
移動用移送筒を伸縮移動させる伸縮装置を回転駆動させる移動モ−タは、固定用移送筒の基部に設けていることにより、この移動用移送筒が最短縮状態に移動制御されたときには、この固定用移送筒の基部まで完全に重合状態となり、このために、該移動モ−タへこの移動用移送筒が当接することがあり、この移動モ−タの破損の原因になることが発生していたが、この発明により、この問題点を解決しようとするものである。
【０００５】
【課題を解決するための手段】
このために、この発明は、次のような技術的手段を講じる。

  As shown in FIG. 5, the pitch of the spiral screw 47a of the transfer shaft 47 is, for example, 40 mm from the base portion (transfer start end) to the substantially central position of the transfer shaft 47. The space up to (transfer end portion) is a configuration in which the spiral screws 47a are formed at a pitch of 20 mm. Moreover, it is good also as a structure which changes sequentially from 40 mm pitch of a base part to 20 mm pitch of a terminal part.
[0042]
  By changing the screw pitch of the helical screw 47a of the transfer shaft 47 to extend the transfer cylinder 22 for movement, the extension speed is increased, and on the extension end side (longest state side), the extension speed is decreased. The low output motor can be used by increasing the thrust applied to the transfer cylinder 22 and reducing the output of the transfer motor 26.
[0043]
  By the forward and reverse rotation of the moving motor 26, the transfer shaft 47 is driven to rotate forward and backward, and the moving transfer cylinder 22 is moved along the outer periphery of the fixed transfer cylinder 23 via the moving support metal 41.

  As shown in FIG. 2, the moving spiral shaft 38 is fitted with a steady prevention bush 38a made of a resin material or the like at the transfer start end, and the outer diameter portion of the bush 38a is connected to a pipe-shaped fixed spiral. As a configuration in which the inner diameter portion of the shaft 34b is slidably moved, the moving spiral shaft 38 is prevented from shaking.
[0045]
  When the moving transfer spiral 30 is molded from a resin material or the like, as shown in FIG. 14, it is divided into front and rear from a substantially central portion of 1.5 pitch, and left and right spiral plates 49a and 49b, The front and rear bosses 50a and 50b are divided and molded.
  As a result, when the total length of the moving transfer spiral 30 is formed with a pitch of 1.5 or less, by dividing from the center portion, a punching die of the resin material can be easily formed, and two divided spirals can be formed. It can be manufactured with a single die, and the cost can be reduced.
