Abstract
Description
即ち、菜種などを収穫する普通型のコンバインでは、扱胴が長く、受網から流下した菜種粒、鞘類、小さな茎部屑等が混在した処理物が選別部で選別処理されることになる。そして、菜種を収穫するときの受網の目合いも小さく設定されるから、チャフシーブでの選別作用に、大きく開度が変わるものを使用すると、処理量が多いときには大部分が風選別されずにそのままチャフ板間から流下してしまい、選別不良が生じる虞がある。
このものは、特許文献1に示されているように、操作レバーに形成した長孔の範囲内でチャフ板が揺動するものではないが、操作レバーを所定の位置に固定した状態では、特許文献1のものと同様、選別板11はスプリング23で閉じ方向に付勢されていて、処理量が多くなる(重くなる)と、スプリング23に抗して選別板11の角度が変化してチャフシーブ7の開度が大きくなる構造となっている。従って、この構造のものをそのまま菜種を脱穀するコンバインに適用すると、特許文献1のものと同様の選別不良が生じる虞がある。
(以上の説明における符号は各特許文献のものである。)
受網とその下方の選別部とを有する脱穀装置を備えたコンバインであって、
前記選別部が、前後揺動可能なシーブケースと、このシーブケースに設けられ前記受網から落下した脱穀処理物を選別するチャフシーブとを備え、
前記チャフシーブが、所定ピッチで前後方向に並列配備され且つそれぞれ横軸芯周りに揺動可能に支持された複数の選別板と、これら複数の選別板に亘って接続された前後方向に長い支持枠とを備え、前記支持枠の前後移動に連動して前記各選別板の角度が変更されることによって前記チャフシーブの開度が設定されるように構成されたものにおいて、
前記チャフシーブの側部に設けた支点軸と前記支持枠に接続された操作軸とに亘って操作部材が設けられ、
この操作部材を前記シーブケースの側板に位置決め用固定部材を介して固定することによって、前記支持枠の前後位置が固定されて前記チャフシーブの開度が設定されるように構成されていることを特徴とするコンバイン。
特に、菜種を収穫する場合は、菜種粒、鞘類、茎部屑などが小さいので、開度が所定開度よりも大きくなると、チャフシーブ上で処理物が選別されずにそのまま選別板間から流下してしまい、選別不良が生じやすい。これに対し、上記第1特徴構成によれは、開度設定されたチャフシーブに対して、処理量が多少多くなっても選別板が揺動しないので(チャフシーブの開度が変化しないので)、処理物に混在する処理屑が多量に選別板間から流下することも回避でき、良好な選別処理を行うことができる。
選別板を操作部材に連結するに当たって、選別板の支点軸だけに操作部材を固定するか、選別板のみに操作部材を連結して、選別板の支点軸を中心に選別板を揺動させて、チャフシーブの開度を変更することも考えられるが、作業中、常に揺動するチャフシーブにおいては支持強度上、不利である。
これに対して、上記第1特徴構成においては、操作部材が前記支点軸と前記操作軸との2軸間に亘って接続され、位置決め用固定部材を介してシーブケースの側板に固定されるので、操作部材が3点で支持および固定される状態となって、操作部材に大きな応力が加わることがなく、操作部材が破損するのも回避させやすい。
したがって、処理物の多少に係らず所定の選別処理が行えるので、菜種などの選別に適した選別処理が行うことができるに至った。又、操作部材を破損させることなく長期に良好に使用することができる。
前記支点軸が、前記複数の選別板のうちいずれか一つの選別板の上端部位又は下端部位の一方に備えられて支点を形成し、
前記操作軸が、前記一つの選別板の上端部位又は下端部位の他方に備えられて前記支持枠に接続されている。
前記操作部材が、前記チャフシーブの側板の外側外面に沿って近接配設され、
前記操作軸が、前記チャフシーブの側板を貫通した状態で前記操作部材と接続され、
前記操作軸の揺動範囲に沿って前記側板に長孔が形成され、この長孔が、前記操作軸の揺動範囲において前記操作部材によって閉塞可能に構成されている。
また、操作部材で長孔を閉塞し、操作部材を長孔の蓋体として機能するようにしてあるので、別途長孔閉塞用の蓋板を設ける必要がなく、部品点数を削減できながら、チャフシーブの開度を変更したときも変更した孔を閉塞する作業も不要となり、チャフシーブの開度変更作業も容易に行える利点がある。
まず、図1~図15を参照しながら、第1実施形態について説明する。
まず、普通型又は全稈投入型(normal type or whole-culm charging type)のコンバインの全体構成について説明する。図1、図2は、コンバインの全体側面図、および全体平面図を示す。図1、図2に示すように、左右一対のクローラ走行装置1を備えた走行機体2の上部に、軸流型の脱穀装置3および作物回収部4が左右に並列して配備されており、作物回収部4の前方に運転部5が配備されている。
普通型コンバインで収穫される処理対象作物としては、稲麦、稗、粟、豆類、ごま、菜種など種々あるが、ここでは、菜種を収穫する処理対象作物としている。以下において収穫の目的とする菜種を穀粒と称し、茎、および穀粒を包んでいた鞘を含めて茎部と称し、場合によっては鞘と茎部を分けていうことがある。
(1)前後いずれかの扱歯44群に叩かれる。
(2)前側の扱歯44群の扱歯44と後側の扱歯44群の扱歯44に連続して叩かれる。(3)前後の各扱歯44群における前後2個の扱歯44に同時に当たって叩かれる。
ことになる。
(1)の場合は、扱胴全長を通過する間の脱穀処理物が扱歯44に叩かれる回数が軽減(半減)されるので、打撃が軽減される。
(2)の場合は、前後の扱歯44に連続的に叩かれるので、後の扱歯44に叩かれるときの脱穀処理物の速度低下が少なく、扱歯44の回転速度と脱穀処理物の回転速度との速度差が小さいから、脱穀処理物が後方の扱歯44に叩かれるときの衝撃が緩和される。
(3)の場合は、一つの脱穀処理物が前後2個の扱歯44に同時に当たるので、衝撃が緩和される。
従って、いずれの場合も全体としての脱穀処理物の衝撃が緩和される。即ち、前後に近接した2組の扱歯44群でもって、これらが対となって全体としての脱穀処理物に対する衝撃を緩和するように機能して脱穀処理が行われる。
脱穀処理物が、対を成す2組の近接した扱歯44群のうち、前側(移送方向上手側)の扱歯44に叩かれた後、引き続いて、対を成す後方の扱歯44群の扱歯44に叩かれる場合(前記(2)の場合)は、前側の扱歯44に打撃を受けた後、直ぐに再打撃を受けることとなる。この場合、対を成す前後2組の扱歯44群の距離(ピッチ)は短く両者は接近しているから、脱穀処理物は短時間の間に続け様に前後の扱歯44に打撃を受けることになる。扱歯44に打撃を受けた脱穀処理物は、瞬間的には扱歯と回転速度と略同速度回転する。脱穀処理物が扱歯から離れると速度低下が生じるが、近接した前後の扱歯44で続け様に打撃を受けると、対を成す後の扱歯44で打撃を受けるときの速度低下は少ないから、後の扱歯44で再打撃されるときの衝撃力が小さく、全体として2組の扱歯44のピッチを短くした場合は、ピッチの広い2組の衝撃力の総和よりも小さくなる。
脱穀処理物が対を成すピッチの短い2組の扱歯44群の前後の扱歯44に略同時に当たったときは(前記(3)の場合)、その前後何れか一方の扱歯44の回転速度と脱穀処理物の回転速度が同速度で当たったことと同じ、即ち、一方が速度差零で当たったとみなせるから、一対の扱歯44に略同に時叩かれたときは衝撃力が概ね半減する。又、対を成す2組の前後の扱歯に完全に同時に叩かれたときも衝撃力は半減する。
以上のように、扱歯44による脱穀処理物に対する衝撃力が緩和されるから、脱穀処理物の茎汁の発生を抑制でき、総じて脱穀負荷も軽減される。
前記シーブケース27における2番回収部31の上方からシーブケース27の後端部に亘って第2チャフシーブ62が前部よりも後部が高い後上がりに設けられている。第2チャフシーブ62には多数の選別板73が所定ピッチで前後に並列配備されている。
選別板73は、開口設定用の操作具75に連結された選別板73Aと、これ以外の前後の選別板73Bとからなる。図12、図13に示すように、選別板73Aは、下端部に流下してきた選別処理物を受け止める補強を兼ねた折り曲げ片73aを形成した板材73bと、板材73bの上端部に固設した丸棒からなる支点軸80と、板材73bの下端部の左右に配置した下部枢支ピンからなる操作軸81と、板材73bの左右に配置され支点軸80と操作軸81とを保持する保持板73cとを備えている。図12、図14に示すように、前後の選別板73Bは、下端部に流下してきた選別処理物を受け止める補強を兼ねた折り曲げ片73aを形成した板材73bと、板材73bの上端部の左右に配置した上部枢支ピンからなる支点軸80aと、板材73bの下端部の左右に配置した下部枢支ピン81aと、支点軸80aと下部枢支ピン81aとを保持し板材73bと重合する補強板73dとを備えている。
第2チャフシーブ62を取外すときは、チョッパ47を大きく開放して、偏芯回動機構51の連結を外して、シーブケース27を後方に引き出してから、ボルト87を外すと取外すことができる。そして、目合いの異なるチャフシーブやストローラックと付け替えることで、異なる種類の収穫物の収穫に対処することができる。
(1)上記実施形態では、第1チャフシーブ59、第2チャフシーブ62の選別板63、73の上端部の横軸芯a、b周りに下端部を揺動させるようにしてあるが、横軸芯a、bと支持枠64、74を上下逆にして、複数の選別板63、73の下端部の横軸芯a、b周りに揺動自在に支持され、複数の選別板63、73の上端部が前後に長い支持枠64、74に接続され、支持枠64、74の前後移動に連動して複数の選別板63、73の角度が変更されて第1チャフシーブ59又は第2チャフシーブ62の開度が設定されるように構成してもよい。

前記脱穀装置113は、下部に風選別室が形成され、上部に前端がフィーダ115に接続された扱室を備えている。扱室の前壁の前方には、扱胴軸を駆動する入力軸等の伝動装置を内蔵した筒状の伝動ケース157を備えている。伝動ケース157は、脱穀装置113の外枠を形成する脱穀装置113の前部の左右の縦フレーム158の上部に架設されている。伝動ケース157の左右の上下に伝動ケース157を縦フレーム158の前面に取り付けるボルト挿通用の取付部159が形成されており、この取付部159のボルト挿通孔にボルトを通して、縦フレーム158の前部に螺着してある。伝動ケース157は、脱穀装置113の外枠を構成する横フレームとして機能している。
前記脱穀装置113は、扱室に供給された刈取り穀稈を走行機体前後向きの軸芯周りに回動する軸流型の扱胴(図外)によって脱穀処理するように構成してあり、その脱穀された被処理物を扱胴の下方に配備された選別処理装置(図外)で脱穀処理物を脱穀粒と藁屑とに選別処理し、脱穀粒を穀粒回収装置103のグレンタンク104に供給するように構成してある。前記グレンタンク104に貯留される対象の脱穀処理物(脱穀粒)以外の藁屑などは、自走機体101の後方に落下放出するように構成してある。
前記グレンタンク104は、タンク本体140の下部に貯留した穀粒を後方に向けて送り出す底スクリュー141を備えて構成されている。
また、図17に示すように、前記グレンタンク104の下部後端には、底スクリュー141の後端部を支承する搬出ケース142が連結されるとともに、グレンタンク104が搬出ケース142とともに上下向き軸心y回りで旋回可能に支持されている。
このガイド体145による案内作用は、穀粒搬出筒170の上下向き軸心y回りの回動範囲で、格納用支持台130が存在する位置から搭乗運転部102が存在する側の機体横端部との間で機能するものであり、これ以外の範囲ではガイド体145による案内作用は生じない。
前記格納用支持台130は、脱穀装置113の天板113aよりも上位に位置していて、縦フレーム158の上部に架設した伝動ケース157の左右横方向中間部に立設したステー164の上端に取り付けてある。
ステー164は、上部ステー164aと下部ステー164bとからなり、両者に形成したピン挿通孔166に挿通したピン165によって固定されている。下部ステー164bには上下2箇所にピン挿通孔166が形成されており、通常使用状態は下部ステー164bの上側のピン挿通孔166にピン165を通して下部ステー164bと上部ステー164aとを連結している(図22の二点鎖線で示す状態)。下部ステー164bの下側のピン挿通孔166にピン165を通して、下部ステー164bに上部ステー164aを連結すると(図21および図22の実線で示す状態)、格納用支持台130に穀粒搬出筒170を載置したとき、穀粒搬出筒170の前端高さを下げることができ、出荷搬送(コンテナ格納)時のコンバインの最大車高を低くすることができる。
ベベルケース175の後部の開口外周にフランジ176が形成されていて、このフランジ176と扱室前壁177が固定連結されている。
通常は、反転用入力軸は動力遮断状態で、正転用入力軸からの動力で扱胴が駆動するようにしており、詰まりが生じた場合に、正転用の入力軸への動力を断って、逆転用の入力軸に伝動するクラッチを入れて扱胴を反転させて詰まりを解消するようにしてある。
前記グレンタンク104の後方には、底スクリュー141によって送出された穀粒を揚送した後に、横搬送して機外に搬出するスクリュー式の穀粒搬出装置105が装備されている。この穀粒搬出装置105は、グレンタンク104の後面下端に連通接続されたスクリュー式の縦搬送機構106と、この縦搬送機構106の上端に連通接続されたスクリュー式の横搬送機構107とから構成されており、穀粒搬出装置105全体が、縦搬送機構106のスクリュー軸心と同芯である上下向き軸心yを中心にして、搬出ケース142に対して旋回可能となっている。
前記縦送り筒160は、その下端側が搬出ケース142の上端側に接続されているとともに、その接続箇所の少し上部の外周にギヤ部160aを備え、そのギヤ部160aに咬合するピニオン162を備えた旋回用電動モータ163によって上下向き軸心y回りで旋回駆動されるように構成してある。旋回用電動モータ163は、搬出ケース142側に固定されている。
前記穀粒搬出筒170は、縦送り筒160の上端ケース167から穀粒搬出方向の下手側に接続された横送り筒部173を備えており、穀粒搬出筒170内部に搬送スクリュー171を装備してある。
穀粒搬出装置105の上下向き軸心y回りでの旋回動作、および横向き軸心x回りでの上下揺動は次のようにして行われる。
これらの第1操作スイッチ132aおよび第2操作スイッチ132bは、運転座席120よりも機体外側に位置するように配置されているので、運転座席120に着座して操作できるとともに、自走機体101から降りて地上からでも操作可能となっている。
この実施形態の構成は、稲麦の穀物や、稗、粟、豆類を脱穀する普通型コンバインの他、刈り取った穀稈をフィードチェーンで挟持しながら脱穀する自脱型コンバインにも適用できる。
以上述べた通り、この実施形態によるコンバインでは、以下の構成を特徴とする。すなわち:-
自走機体の左右方向の一方に脱穀装置を、他方にグレンタンクを備え、前記グレンタンク内の脱穀物を搬出する穀粒搬出筒を、前記グレンタンクの後部に位置する上下向き軸心回りに旋回自在に且つ横向き軸心回りに上下方向に揺動自在に備え、前記穀粒搬出筒の長手方向中間部を載置支持する格納用支持台を前記脱穀装置の前部に設けてあるコンバインであって、前記脱穀装置の外枠を形成する該脱穀装置前部の左右の縦フレームの上部に横フレームを架設し、この横フレームの左右方向中間部に立設したステーを介して前記穀粒搬出筒の格納用支持台を設けてある。
これによれば、穀粒搬出筒の格納用支持台を、左右の縦フレームと、この縦フレームの上部に架設された横フレームとで構成された丈夫な門形のフレーム枠の上部に設けたので、前記横フレームと格納用支持台との間に介装されるステーの丈を短くできる。
また、脱穀装置の横幅に相当する間隔を備えた左右の縦フレームにより、ステーおよび格納用支持台が二股状に十分な強度で支持される。
したがって、穀粒搬出筒の格納用支持台を設けるに当たって、脱穀装置の外枠を形成する既存の部材である左右の縦フレームを有効利用することにより、機体フレームから専用の長い支柱を設ける必要はなく(ステーを支持するための専用の部材を備えたとしても、小規模のものでよく)、短い丈のステーで簡便に形成することができる。そして、ステーの強度としては短柱としての強度があればよく、小型軽量のステーとすることができ、軽量化を図ることができる。
好適には、上記構成において、前記横フレームが脱穀装置の扱胴を駆動する伝動装置を内蔵した伝動ケースとされる。
この構成によれば、脱穀装置を駆動する伝動装置を内蔵した既存の部材である伝動ケースを、ステーを支持する横フレームを兼ねている。したがって、ステーおよび格納用支持台の支持構造を簡略化することができる。
次に、図26~図37を参照しながら、第3実施形態について説明する。
しかしながら、例えば図37に示すように、縦オーガ208が反時計回りに回動するときに(図37(a)を参照)、縦オーガ208の回動の慣性や位置検出機構232の検出不良等により、縦オーガ208が所定の回動範囲(図37(b)を参照)を超えて移動する場合がある。このとき、回動レバー232aが突出ピン231から外れる場合がある(図37(c)を参照)。回動レバー232aが突出ピン231から外れると、回動レバー232aが他方側に揺動して中立位置(図37(c)の回動レバー232aの2点鎖線の位置)に弾性復帰する。この状態から縦オーガ208が時計回りに回動すると、回動レバー232aが中立位置(図37(d)の回動レバー232aの2点鎖線の位置)から他方側に揺動することになり(図37(d)を参照)、回動レバー232aの位置が適正検出範囲から外れて位置検出機構が故障することがある。
また、上側の突出ピン231aが下側の突出ピン231bよりも長い構成を例示したが、上側の突出ピン231aと下側の突出ピン231bとが同じ長さでもよく、あるいは、上側の突出ピン231aが下側の突出ピン231bよりも短くてもよい。また、上側の突出ピン231aと下側の突出ピン231bとを1組設ける構成を例示したが、上側の突出ピン231aと下側の突出ピン231bとを複数組設けてもよい。
さらに、リングギヤ221のいずれか一方の面から突出する突出ピン231を設け、その突出ピン231に接触して揺動可能な回動レバー232aを有する一対の位置センサ232、および、その突出ピン231に当接して縦オーガ208の回動を規制する一対の固定のストッパ233を設けてもよい。
(1)上記実施形態では、モータMを、ブラケットBを介して機体フレーム202の第1縦フレーム222に取り付ける構成を例示したが、このような構成に限られるものではなく、モータMを、ブラケットBを介して機体フレーム202のロアケース212に取り付ける構成としてもよい。
以上述べた通り、この実施形態による作業車(コンバイン)は、以下の構成を特徴とする。すなわち:-
アクチュエータの駆動により移動可能な移動体と、前記移動体に取り付けられた被検出体と、前記被検出体に接触して揺動可能な接触子を有する位置検出機構と、前記位置検出機構にて被検出体を検出するとアクチュエータの駆動を停止させる制御機構とを設けたものであって、その第1特徴構成は、前記被検出体に当接して移動体の移動を規制する固定のストッパを設け、前記接触子が被検出体に接触した状態を維持しながら、前記被検出体がストッパに当接するように、前記位置検出機構およびストッパを配置してある。
本構成によれば、アクチュエータをブラケットを介して移動体に対して機体フレームの側に取り付けると共に、そのブラケットに位置検出機構およびストッパを取り付けてあるので、アクチュエータを移動体に対して機体フレームの側に取り付けるためのブラケットを位置検出機構およびストッパを取り付ける構成に兼用して構成の簡素化を図ることができる。
本構成によれば、回転体の外周部にリングギヤを設けると共に、そのリングギヤの両側面に突出ピンを設け、位置検出機構およびストッパをリングギヤを挟んで振り分け配置してあるので、リングギヤを挟んで位置検出機構およびストッパが振り分け配置されることになり、全体のコンパクト化を図ることができる。
以下、図38~図49を参照しながら第4実施形態について説明する。
図38にはコンバインの全体側面が示されており、このコンバインは、左右一対のクローラ式走行装置301の駆動で走行する機体302の前部に、刈取対象穀稈を刈り取って後方に向けて搬送する搬送装置としての刈取搬送装置303を左右向きの第1軸心X1周りに上下揺動可能に連結し、その刈取搬送装置(搬送装置)303からの刈取対象穀稈に対して脱穀処理を施すとともに、この脱穀処理で得られた処理物に対して選別処理を施す脱穀装置304や、この脱穀装置304からの穀粒を貯留する穀粒タンク305などを機体302に搭載し、機体302における穀粒タンク305の前方箇所に搭乗運転部306を形成して、稲や麦などを刈取対象穀稈とした全稈投入型に構成されている。
下受ディスク322Bを支持するアングル状の受フレーム323を機体302の上下向き前端フレーム302Aから前方に向けて延出し、受フレーム323の前端部を、ミッションケース324から左右クローラ式走行装置301の駆動輪に向けて延出された前車軸ケース325に支持させている。
このような構成によって、駆動ロッド軸344は、駆動フォーク部343の左右揺動に連動して、駆動ロッド軸自体の軸芯Z周りで揺動自在に構成されている。
以上のような構成によって、可動刃332は、偏芯駆動ユニットC1の入力スプロケット337、駆動軸336、回転コア部339、揺動ホルダー部341、駆動フォーク部343、駆動ロッド軸344、揺動駆動ユニット347、駆動アーム347Aを介して伝達された駆動力によって左右に往復駆動される。
連係部材350は、その下端部に副切断装置314の連結フレーム315に連結ピン352で連結可能な取付孔と、上下中間位置に板状の中間連結部材354を装着し、中間連結部材354の装着部位に、連係部材350自身の長手方向に沿った長孔353を形成して、構成してある。また、連係部材350の上端部には、握り操作具355が形成してあり、握り操作具355は搭乗運転部306から操縦者が握り操作することが可能な高さに位置している。
連係部材350は、弾性の高い鋼板で構成してあり、握り操作具355を握って機体の左右方向、すなわち、連係部材350の板面に直交する方向で少し揺動操作すると、自身の弾性で撓み変形し、中間連結部材354に形成した係合用孔部354aと係合操作体351との相対位置を変更操作して、係脱操作を行うことができる。
つまり、係合片356は、平行に延出された脚部356a、356bと脚部同士を連結する基端部356cとを一体に曲げ形成されている。基端部356cをブラケット内部空間内に位置させて、基端部356cから抜き差し方向に両脚部356a、356bをブラケット349から延出させる状態で係合片356はブラケット349に取り付けられている。
ただし、刈取搬送装置303が刈り高さ制御範囲を越えて大きく上昇する場合には、長い脚部356aが係合用孔部354aの上端に当接し、連係部材350とともに副切断装置314は刈取搬送装置303と一体で上昇する。
尚、図47および図48中に示す符号358は、前記スライド用の長孔353に挿入された一方の脚部356aがそのスライド用の長孔353から抜け出すことを防止するためのワッシャであり、符号359は抜止ピンである。
刈取搬送装置303を刈り高さ制御によって、昇降作動させた場合にも、ガススプリング369を伸縮作動させることによって、副切断装置314の高さを付勢手段Aに受止られた略一定高さ位置に維持することができる。つまり、刈取搬送装置303を上昇作動させると、その上昇作動につれてガススプリング369のピストン369Bが伸長作動して、副切断装置314を略一定位置に維持する。
(1) 昇降フレーム313を上向き付勢する付勢手段Aとしては、コイルバネ219を利用したものを説明したが、コイルバネ以外の板バネ、皿バネ等のバネ構造を呈するものでもよい。或いは、バネ以外のオイルダンパー等も使用できる。
すなわち、図49に示すように、副切断装置314を支持する連結フレーム315から略三角形状の取付用ブラケット360を立設し、取付用ブラケット360の前端上部の前面にベアリングホルダー361を取付け、ベアリングホルダー361内にベアリング362を装入して、ベアリング362で偏芯駆動ユニットC1から前方下向きに延出された駆動ロッド軸344の先端部を挿通支持してある。
取付用ブラケット360の後端部における横側面に、付勢手段A用の上受ブラケット363を固定してある。受ブラケット363の下方には、機体302から延出されたアングル状の下受ブラケット364を設けてある。上下受ブラケット363、364に亘って芯軸365を設けてあり、下受ブラケット364には芯軸365を保持する筒状ホルダー366が装着してあり、芯軸365の上端近くに受プレート367を装着して、受プレート367と下受ブラケット364の間に圧縮式コイルバネ368を介在させて芯軸365に外嵌装着してある。
このような構成によって、図示していない昇降フレーム313、付勢手段A、駆動ロッド軸344を単一の取付用ブラケット360で支持できる。
以上述べた通り、この実施形態によるコンバインは、以下の構成を特徴とする。すなわち:-
植立穀稈の穂先部分を刈り取る主切断装置と、切断後に前記穂先部分を搬送する搬送装置とを、機体に昇降自在に取り付け、前記主切断装置より低い位置で前記植立穀稈に作用する副切断装置を機体に対して昇降自在に支持し、
前記副切断装置を上昇側に付勢する付勢手段を設けてある。
このように副切断装置を上昇側に付勢するだけの簡単な改造を施すことによって、刈り株高さを低く揃えることができながら、凸部に対しても干渉を回避することができる副切断装置を備えたコンバインの刈取前処理構造を提供することができた。
このように構成すれば、副切断装置が昇降フレームに取付られているので、副切断装置を昇降フレームにより安定して昇降自在に支持させることができ、凸部に追従して軽快に副切断装置を昇降作動させて干渉を回避できるとともに、大きな凸部が圃場に存在しても、副切断装置が昇降フレームとともに大きく昇降作動することができるので、凸部に干渉することなく副切断装置を退避させることができる。
このように、軽快に昇降作動させる付勢手段と大きく上昇回避する昇降フレームに副切断装置を取り付ける改造を施すことによって、両機能によって凸部を回避して、大きな凸部に対しても干渉を回避することができる副切断装置を備えたコンバインを提供することができる。
この構成によれば、橇が接地するので、前記付勢手段の付勢力と相俟って、副切断装置が刈取り面の凹凸部に追従しやすく、かつ、凸部に突っ込む等の不測な事態を回避し易い。
この構成によれば、植立穀稈の長短に応じて主切断装置を上下動調節する場合等においては、主切断装置と副切断装置との上下間隔は所定間隔未満に抑えられるところから、副切断装置は連動せずに、刈り高さを変動させない。
これによって、主切断装置で着粒部を刈り取られた植立茎稈は、副切断装置によって一定の刈株高さで刈り取られるので、圃場に残る刈り株高さは一定である。
例えば、畦際での旋回時において、刈取前処理部を大きく上昇させる際には、主切断装置と副切断装置の上下間隔が所定間隔以上となるので、連動機構が作用して、副切断装置も上昇する。これによって、畦際での旋回時においては、副切断装置が圃場面等と干渉することはない。
したがって、副切断装置が機能しなければならない刈取時においては、一定の適切な高さで植立茎稈の刈取を行うことができる。
畦際旋回時等の刈取作業を必要としない場合には、主切断装置に連動させて副切断装置を上昇退避させることができ、主副切断装置が不測に障害物と干渉することを未然に回避できる。
この構成によれば、主切断装置を機体に対して昇降作動する搬送装置に設け、副切断装置を機体に取り付けた昇降フレームに取り付けることによって、主切断装置と副切断装置とを分離して、主切断装置が刈高さ調節によって上下動しても副切断装置を連動しない状態にできる。
そして、畦際旋回時等においては、主切断装置と同様に副切断装置を圃面から上方に退避させる必要があるので、連係部材で昇降フレームを搬送装置に連結し、主切断装置と副切断装置を連動した。したがって、搬送装置と昇降フレームの上下間隔が所定間隔以上になると、連係部材が機能して昇降フレームを搬送装置の上昇作動に連動する。
このように、昇降フレームと搬送装置とを、主切断装置と前記副切断装置との上下間隔が一定以上になることを制限する連係部材で連係している。よって、機械的な連係機構によってコストを安くできる。
