【産業上の利用分野】
本発明は連続的に穀稈を刈取って脱穀するコンバインに関する。
【0002】
【従来の技術】
従来、脱穀部にフィードチェンを設け、刈取部から穀稈搬送機構を介して送給される刈取り穀稈をフィードチェンに受継ぎ、連続的に穀稈を刈取り乍ら脱穀し、穀粒を収集する技術があった。
【0003】
【発明が解決しようとする課題】
前記従来技術は、脱穀部一側にフィードチェンを取付け、脱穀部の駆動力によりフィードチェンを駆動していたから、フィードチェンの支持部材を脱穀部に特別に設ける必要がある。また、刈取部を機体一側外方に展開動作させるとき、フィードチェンと共にこの取付け体を機体一側外方に展開動作させる必要がある。このように、フィードチェン取付け構造の簡略化並びに保守修理作業などの取扱い操作性の向上などを容易に図り得ない等の問題があった。さらに、脱穀部に刈取り穀稈を送給する穀稈搬送機構の駆動入力部が刈取部の回動支点軸よりも高く位置すると、刈取部の上昇によって穀稈搬送機構が脱穀部方向に大きく移動するから、穀稈搬送機構の後退用スペースを大きく形成する必要があると共に、穀稈搬送機構の支持部を刈取部の回動支点軸上に設けると、刈取部の上昇回動によって穀稈搬送機構がフィードチェンに側面視で重なり合い、穀稈の受継が面倒になる不具合があった。
【0004】
【課題を解決するための手段】
然るに、本発明は、刈取部及び脱穀部を備え、刈取部を駆動する刈取入力を伝達させるギヤケースを設けるコンバインにおいて、刈取フレームを固定させる刈取回動支点軸を、機台の左右フレームに回転自在に取付け、脱穀部前側に支点軸を横架させ、支点軸一端部を受体によって一方のフレームに着脱自在かつ回転自在に軸支させると共に、サイドオープン支点軸を介してもう一方のフレームにギヤケースを回転自在に取付け、ギヤケースに前記支点軸の他端部を回転自在に軸支させるとともに、支点軸の中空に回転自在に内挿した1軸に、ギヤケースに取付けたスプロケットを連結して、このスプロケットでフィードチェンを駆動し、さらに、スプロケット及びチェンを内設した伝動ケースを介して1軸に連結した入力軸で搬送チェンを駆動することにより、穀稈を刈取部から脱穀部に搬送する搬送チェンと、脱穀部のフィードチェンとを同調駆動させた。
【0006】

【0007】
さらに、図1、図4乃至図7に示す如く、前記刈取フレーム(12)基端を固定させる刈取回動支点軸(22)を備え、機台(3)前部上面の左右フレーム(23)(23)に前記支点軸(22)両端部を回転自在に取付け、脱穀部(4)前側に略水平に支点軸(22)を横架させるもので、支点軸(22)右端部を受体(24)によって右フレーム(23)に着脱自在かつ回転自在に軸支させると共に、略垂直なサイドオープン支点軸(25)を介して左フレーム(23)にギヤケース(26)を水平方向に回転自在に取付け、ギヤケース(26)に前記支点軸(22)左端部を回転自在に軸支させる。
【0008】
また、前記支点軸(22)の中空に1軸(27)を回転自在に内挿させ、刈取フレーム(12)の2軸(28)にベベルギヤ(29)を介して1軸(27)中間を常時連結させると共に、前記1軸(27)右端に刈取入力プーリ(30)を固定させ、刈取入力プーリ(30)にミッションケース(31)の出力プーリ(32)をベルト(33)連結させる。前記ミッションケース(31)の入力プーリ(34)にエンジン(21)の出力プーリ(35)をベルト(36)連結させると共に、左右走行クローラ(2)(2)を駆動するための左右スプロケット(37)(37)を有する左右車軸(38)(38)をミッションケース(31)に設け、エンジン(21)駆動力をミッションケース(31)から車軸(38)と刈取入力プーリ(30)に伝え、走行クローラ(2)と刈取部(8)を同調駆動するように構成している。
【0009】
さらに、前記フィードチェン(5)と略平行に回動支点軸(22)から後方にギヤケース(26)を延設させ、フィードチェン(5)を駆動するためのスプロケット(39)をギヤケース(26)の後部左側に取付け、ベベルギヤ(40)及びウォームギヤ(41)を介して前記1軸(27)にスプロケット(39)を連結させるもので、刈取部(8)及び脱穀部(4)を備えるコンバインにおいて、刈取部(8)を駆動する刈取入力を分岐してフィードチェン(5)に伝達させるギヤケース(26)を設け、刈取り駆動力を利用してフィードチェン(5)を駆動し、刈取部(8)とフィードチェン(5)を伝動上で連動させ、また刈取回動支点軸(22)にギヤケース(26)を介してフィードチェン(5)を取付け、フィードチェン(5)の支持部材を特別に設ける必要がなく構造の簡略化を行えると共に、フィードチェン(5)を機体左側外方に水平回転させて展開させるだけで刈取部(8)を機体左側外方に水平回転させて展開させるサイドオープン操作を行えるように構成している。
【0010】
さらに、スプロケット(42)(43)及びチェン(44)を内設させる伝動ケース(45)を前記支点軸(22)左側端に固設させ、図7に示す如く、前低後高に伝動ケース(45)を斜設させ、刈取フレーム(12)と伝動ケース(45)を側面視で略平行に配設させ、伝動ケース(45)後端を前記支点軸(22)に一体連結させると共に、伝動ケース(45)前端側に搬送駆動入力軸(46)を略垂直に立設させ、上部搬送タイン(47)及び下部搬送チェン(48)を備える穀稈搬送機構(10)後側部を前記入力軸(46)に装設させるもので、前記チェン(44)及びベベルギヤ(49)を介して前記入力軸(46)を1軸(27)に連結させると共に、前記支点軸(22)を中心とする刈取部(8)昇降時、フィードチェン(5)上側搬送面乃至上方を前記搬送チェン(48)が昇降すべく、前記入力軸(46)が略垂直に昇降するように構成している。このように、穀稈搬送機構(10)を設けて刈取り穀稈を刈取部(8)から脱穀部(4)に送給させるコンバインにおいて、刈取部(8)の回動支点軸(22)上に設ける伝動ケース(45)を前方下方に向けて延設させ、穀稈搬送機構(10)の駆動入力軸(46)を伝動ケース(45)の前方下方側に立設させ、穀稈搬送機構(10)の駆動入力部を刈取回動支点軸(22)よりも低くし、刈取部(8)上昇によって穀稈搬送機構(10)が脱穀部(4)方向に移動する量を従来よりも少なくし、刈取回動支点軸(22)を脱穀部(4)に従来よりも接近させてコンパクトに構成させると共に、穀稈搬送機構(10)の支持部が刈取部(8)の回動支点軸(22)よりも低くなり、刈取部(8)の昇降に関係なくフィードチェン(5)上方に穀稈搬送機構(10)を配置させ、穀稈搬送機構(10)からフィードチェン(5)への穀稈受継を常に良好に行わせるものである。
