The lower end of the outside air introduction pipe 320 is connected to the air cleaner 340 via the introduction pipe 330 (see FIGS. 8 to 10). The outside air introduction pipe 320 is supported by the lower part 60B (concave part 60D) of the Glen tank 60.
- the air cleaner 340 is for further purifying the outside air sent through the pre-cleaner 310.
- the air cleaner 340 removes fine dust contained in the outside air.
- the outside air purified by passing through the air cleaner 340 is sent to the combustion chamber of the engine 55 and used for combustion.
- the lower end portion of the outside air introduction pipe 320 is placed above the hole 60v formed in the upper surface 60m of the lower portion 60B of the Glen tank 60 and the hole 60w formed in the right inclined surface 60d of the lower portion 60B of the Glen tank 60.
- the outside air introduction tube 320 penetrates the upper surface 60m and the right inclined surface 60d in an obliquely upward and downward direction (see FIGS. 11 and 13).
- the flange 322 fixed in the middle of the outside air introduction pipe 320 is overlapped with the upper surface 60m of the lower portion 60B of the Glen tank 60, and the flange 322 is fixed to the upper surface 60m with a bolt or the like (FIG. 11).
- FIG. 13 the midway part of the outside air introduction pipe 320 is supported by the lower part 60B (recessed part 60D) of the Glen tank 60.
- a plate 350 having an opening corresponding to the outer shape of the outside air introduction pipe 320 is fitted from below into the outside air introduction pipe 320 protruding from the right slope 60d of the lower part 60B of the grain tank 60 to the outside of the grain tank 60. Then, the plate 350 is overlaid on the right slope 60d of the lower portion 60B of the Glen tank 60, and the plate 350 is fixed to the right slope 60d using a bolt or the like (see FIGS. 11 and 13). By doing so, the gap between the hole 60w of the right slope 60d and the outside air introduction tube 320 is blocked by the plate 350, and the grains in the grain tank 60 are prevented from spilling from the gap. Further, the outside air introduction pipe 320 is supported by two upper and lower positions of the upper surface 60m and the right inclined surface 60d of the Glen tank 60, thereby preventing rattling.
- the flange 312 is overlapped with the upper surface 60n of the lower portion 60B of the Glen tank 60 and the flange 321, and the flange 312 is fixed to the upper surface 60n and the flange 321 with a bolt or the like.
- the upper end of the outside air introduction pipe 320 is supported by the upper surface 60n of the lower portion 60B of the Glen tank 60.
- the precleaner 310 is connected to the upper end of the outside air introduction pipe 320 via the pipe 311.
- the pre-cleaner 310 is disposed at a position lower than the opened uppermost surface of the upper part 60A of the Glen tank 60, the dust released from the opened uppermost face of the upper part 60A of the Glen tank 60 is pre-cleaned. It is difficult to be sucked by the cleaner 310. Even when the present invention is applied to a combine having a structure in which the top surface of the Glen tank is closed by a lid or the like, the dust is blocked by the wall surface (rear surface) of the Glen tank, so the precleaner sucks the dust. It becomes difficult to do.
- the combine 1 has the engine room 50 disposed at the rear of the fuselage, the Glen tank 60 disposed above the engine room 50 and behind the control unit 40, and the rear part of the Glen tank 60.
- the outside air introduction pipe 320 which is a part of the outside air introduction path 300 to the engine 55 in the engine room 50 is arranged so as to penetrate the Glen tank 60 in the vertical direction. It is what is done. Therefore, regardless of the arrangement of the outside air introduction pipe 320 of the engine 55, the Glen tank 60 can be expanded above the engine room 50, and the capacity of the Glen tank 60 can be sufficiently increased.
- tube 320 is supported by the lower part 60B of the Glen tank 60. As shown in FIG. Therefore, it is not necessary to separately provide a support member such as a frame in order to support the outside air introduction tube 320, and the structure can be simplified.

Abstract
Description
特許文献1に記載のコンバインの機体の前部には、操縦部が設けられ、該操縦部の後方には、脱穀後の穀粒を貯溜するためのグレンタンクが配置されている。そして、該グレンタンク内の穀粒を機外に排出するための排出オーガが、グレンタンクの後部と連通するように設けられている。排出オーガは、非作業時には、機体の右外側に突出するように設けられたオーガレストに載置されている。
また、特許文献1に記載のコンバインには、排出オーガへの動力伝達を断接するオーガクラッチが設けられており、該オーガクラッチを操作するためのオーガクラッチ操作具(手動操作レバー)が、操縦部における座席の左方に配置されている。
このような構成のコンバインにおいて、収穫作業の途中でグレンタンクが満杯になった場合、収穫作業を中断して穀粒を機外に排出する必要がある。具体的には、例えばコンバインをダンプトラックの荷台の近傍に移動させるとともに、排出オーガを右方向に回動させて、該排出オーガの先端(排出口)をコンバインの機体の右側方または右後方に向ける。こうして、排出オーガの先端をダンプトラックの荷台の上に合わせた状態として、オーガクラッチ操作具によりオーガクラッチを入操作することにより、グレンタンク内の穀粒をダンプトラックの荷台に排出することができる。
このような構成のコンバインにおいて、連続刈取作業時間を出来るだけ長くして作業効率を向上させようとすると、グレンタンクの容量を大きく設定する必要がある。このような観点からは、グレンタンクを、エンジンルームの上方にわたるように配置することが望ましい。

排出オーガ65は、縦排出オーガ65A及び横排出オーガ65B等により構成される。
縦排出オーガ65Aの下端部は、グレンタンク60の底部に設けられた前記排出コンベアの後端部に接続される。縦排出オーガ65Aの上端部は、横排出オーガ65Bの基端部(上流側の端部)に接続される。
横排出オーガ65Bの前記横排出コンベアの基端部は、縦排出オーガ65Aの前記縦排出コンベアの上端部とベベルギヤ等を介して連動連結される。
第二の軸413と同軸上の前方には前記排出コンベアが設けられており、第二の軸413が回転することにより前記排出コンベアに動力が伝達されるようになっている。
第三の軸431の前端部は、ベベルギヤ等を介して、縦排出オーガ65Aの前記縦排出コンベアの下端部と連動連結されている。すなわち、第三の軸431が回転することにより縦排出オーガ65Aの前記縦排出コンベアに動力が伝達され、また、該縦排出コンベアに動力が伝達されることにより、ひいては横排出オーガ65Bの前記横排出コンベアにも動力が伝達されるようになっている。
オーガクラッチ420は、前記排出コンベア及び排出オーガ65への動力伝達を断接するためのものである。図5に示すように、オーガクラッチ420はグレンタンク60の後方に配置される。オーガクラッチ420は、いわゆるベルトテンション式のクラッチであり、アーム421、テンションプーリ422、及びアーム423等により構成される。
アーム421は棒状の部材であり、その一端部がコンバイン1の機体に対して回動可能に支持される。アーム421の他端部には、テンションプーリ422が回転自在に支持される。アーム421の中途部は、アーム423及びスプリングを介して、操作ワイヤー425の一端部に連結される。操作ワイヤー425の他端部は、後述するオーガクラッチ操作部440に具備されるレバー441に連結される。
但し、本発明に係るオーガクラッチはベルトテンション式のものに限定するものではなく、摩擦板式のもの等であってもよい。すなわち、本発明に係るオーガクラッチは、操作ワイヤーの押し引き操作により断接できるクラッチであればよく、その構成を本実施形態のものに限定するものではない。
オーガクラッチ操作部440は、オペレータがオーガクラッチ420(図5参照)を人為的に入切操作するためのものである。オーガクラッチ操作部440は、ボックス442、支持軸443、プレート444、レバー441、及びストッパ445等により構成される。
ボックス442は、板面がコンバイン1の機体の前上方を向くように配置される傾斜面442aを有し、該傾斜面442aにはレバー441の操作方向を案内するための溝であるレバーガイド442bが形成される。レバーガイド442bには、レバー441を入位置に係止するための係止部442cが形成される。
本実施形態では、係止部442cに係止されたときのレバー441の位置が入位置であり、レバーガイド442bの後上端まで到達したときのレバー441の位置が切位置である。なお、切位置においてはストッパ片444cがストッパ445に当接することにより、レバー441のそれ以上の切方向への回動が規制される。
一方、レバー441を入位置から切位置に切り替えたとき、ワイヤー軸444bの位置が後方へ移動して操作ワイヤー425の他端部(前端部)が前方に引っ張られなくなり、これに伴ってテンションプーリ422が第二の伝動ベルト417に押し出されてアーム421が図5における反時計回りに回動し、テンションプーリ422が第二の伝動ベルト417に押し付けられない状態となってオーガクラッチ420が「切」となる。
以下では、取っ手450について、図3、図4、及び図6を参照して説明する。
取っ手450は、その軸線をコンバイン1の機体の前後方向に向けた状態で、グレンタンク60の機体外側の側面(脱穀装置31が配置される側とは反対側の側面)に取り付けられる(図3及び図4参照)。より詳細には、本実施形態の取っ手450は、グレンタンク60の右側面60yに、ステー等を介して固定されており、グレンタンク60の右外側に突出するように配置されている。つまり、取っ手450は、右側面60yと取っ手450の間に指を挿入することにより握れるようになっている。
よって、排出オーガ65による穀粒の排出状況を視認しながらレバー441を操作することが可能である。
よって、オペレータがグレンタンク60の機体外側の側方で作業する際に使用する取っ手450を利用(兼用)して、操作ワイヤー425を案内することができ、部品点数の削減を図ることができる。
グレンタンク60は、脱穀後の穀粒を貯溜するタンクである。詳細には、脱穀装置31で脱穀されて藁屑等と選別された一番穀粒が、揚穀装置90によりグレンタンク60内に搬入されて、該グレンタンク60内に貯溜される。
図8~図10に示すように、グレンタンク60の後部において、下部60Bは上部60Aよりも後方に長く形成され、このグレンタンク60の下部60Bの、後方に長い部分の右側に上面60mが形成され、左側に上面60nが形成されている。グレンタンク60の下部60Bの後端部右側の上面60mは、後端部左側の上面60nに対して一段低くなっている。言い換えれば、グレンタンク60の下部60Bの後端部右側には、凹部60Dが構成されている。当該凹部60Dは、プレクリーナ310及び外気導入管320を配置するスペースとして利用される。
グレンタンク60の上部60Aの後板60qは、後側に向かって低くなる傾斜面となっている。こうして、後述するプレクリーナ310との間に空間を形成するとともに、上部60Aの上後端とプレクリーナ310との間の距離をなるべく長くして、上部60Aの開放された上面から舞い上がる塵埃がプレクリーナ310に吸い込まれ難いようにしている。
図3に示すように、エンジンルーム50内の、エンジンフレーム51で取り囲まれた部分には、コンバイン1の駆動源であるエンジン55が配置される。エンジン55の給気部(給気マニホールド)には、外気導入経路300を介して、燃焼用の外気が送り込まれるようになっている。なお、エンジン冷却用の空気は、右側面の開口部より吸入される。
外気導入経路300は、プレクリーナ310、外気導入管320、導入管330、及びエアクリーナ340等により構成される。
図11及び図12に示すように、外気導入管320の上端には、該外気導入管320をパイプ311に接続するためのフランジ321が固設される。外気導入管320の下端は、導入管330を介してエアクリーナ340に接続される(図8~図10参照)。外気導入管320は、グレンタンク60の下部60B(凹部60D)に支持される。
また、グレンタンクの最上面が蓋等により閉塞されている構成のコンバインに本発明を適用した場合であっても、グレンタンクの壁面(後面)により塵埃が遮られるため、プレクリーナが塵埃を吸引し難くなる。
よって、エンジン55の外気導入管320の配置に関わらず、グレンタンク60をエンジンルーム50の上方まで拡張し、グレンタンク60の容量を充分に大きくすることができる。
よって、外気導入管320を支持するために別途フレーム等の支持部材を設ける必要がなく、構造を簡素化することができる。
よって、プレクリーナ310が、グレンタンク60の最上面から放出される塵埃を吸引し難くなる。また、グレンタンクの最上面が蓋等により閉塞されている構成のコンバインに本発明を適用した場合であっても、グレンタンクの壁面により塵埃が遮られるため、プレクリーナが塵埃を吸引し難くなる。
