Description

本発明は、走行機体に脱穀装置を搭載するとともに前記脱穀装置の後方に、前記脱穀装置からの排ワラを処理する排ワラ処理装置を設けてあるコンバインに関する。   The present invention relates to a combine in which a threshing device is mounted on a traveling machine body and a waste straw processing device for treating waste straw from the threshing device is provided behind the threshing device.

脱穀装置と穀粒貯留装置とを左右に並設するとともに、脱穀装置における前記穀粒貯留装置存在側とは反対側の横側面に縦向き軸芯を介して排ワラ処理装置を後方に向けて揺動開閉自在に取付け、前記排ワラ処理装置を前記脱穀装置に対して離間する非処理姿勢に開放自在に構成してあった(特許文献1参照)。   A threshing device and a grain storage device are juxtaposed side by side, and the waste straw processing device is directed rearward through a longitudinal axis on the side surface of the threshing device opposite to the side where the grain storage device is present. It attached so that rocking | fluctuation opening and closing was possible, and it comprised so that the said waste straw processing apparatus could be freely opened to the non-processing attitude | position which spaces apart with respect to the said threshing apparatus (refer patent document 1).

特開平10−215658号公報(段落番号〔0016〕及び、図1,5)JP-A-10-215658 (paragraph number [0016] and FIGS. 1 and 5)

上記構成においては、排ワラ処理装置を後方に開放できるだけであるので、排ワラ処理装置の外装ケースとその排ワラ処理装置の具体的手段であるチョッパー等の排ワラ細断刃との間に詰まっているワラ屑等を取り除く必要があっても、排ワラ処理装置の開放面側からは詰まり部位が手の届きにくい背面側になるので、メインテナンス作業が困難な状況になっていた。
一方、排ワラ処理装置をチョッパー等を備えた排ワラ処理装置本体とその本体を覆うカバーとを設け、カバーを後方に開放するだけの構成を採ることも考えられるが、この場合には排ワラ処理装置本体が開放できないので、脱穀装置内のチャフシーブ等に対するメインテナンス作業が困難になる欠点があった。
排ワラ処理装置を揺動開閉する縦向き軸芯の設置位置が脱穀装置における穀粒貯留装置存在側とは反対側の横側面に設けてあるので、排ワラ処理装置を後ろ向きに開放した場合に、排ワラ処理装置が走行機体の横側方へはみ出すことになる。そのために、排ワラ処理装置に近接して壁面が有る場合は十分に開放できず、メインテナンス作業姿勢が窮屈になる欠点や、十分に開放できるとしても大きく機体外側にはみ出すことになるので、他物が接触する等の欠点がある。
In the above configuration, since the waste straw processing apparatus can only be opened rearward, it is clogged between the outer case of the waste straw processing apparatus and the waste straw shredding blade such as a chopper which is a specific means of the waste straw processing apparatus. Even if it is necessary to remove the waste straw etc., maintenance work is difficult because the clogged portion is located on the rear side which is difficult to reach from the open side of the waste straw treatment apparatus.
On the other hand, it is conceivable to adopt a configuration in which the waste wall treatment apparatus is provided with a waste wall treatment apparatus body provided with a chopper and a cover that covers the body, and the cover is simply opened rearward. Since the processing apparatus main body cannot be opened, there is a drawback that it is difficult to perform maintenance work on the chaff sheave in the threshing apparatus.
Since the installation position of the vertical axis that swings and opens the waste straw processing device is provided on the side surface opposite to the grain storage device existing side in the threshing device, when the waste straw processing device is opened backward Then, the waste straw processing apparatus protrudes to the lateral side of the traveling machine body. Therefore, if there is a wall in the vicinity of the waste wall treatment device, it cannot be fully opened, and the maintenance work posture will be cramped, and even if it can be fully opened, it will protrude greatly outside the aircraft, so other things There are drawbacks such as contact.

本発明の目的は、脱穀装置内機器のみならず、排ワラ処理装置内での詰まり等を容易に取り除き回復作業を行い得るコンバインの排ワラ処理装置取り付け構造を提供する点にある。   An object of the present invention is to provide a combine drainer processing device mounting structure for a combine that can easily remove clogs and the like in the drainer processing device as well as the equipment in the threshing device and perform a recovery operation.

尚、図4に示すように、カバー55の左側面に突設してある丸棒枠材59は、出力プーリ36等の駆動部を覆う車体カバー60のロック金具60Aに対する係止部材である。
Next, the buckle-type fasteners 58, 58 that maintain the closed state of the cover 55 will be described. As shown in FIGS. 10 and 11, hook metal fittings 58A are provided on both side surfaces of the cover 55, and receiving metal fittings 58B are provided on the corresponding portions of the outer case 26, respectively, so that the cover 55 is set in the closed position. The front end swinging portion 58a of the metal fitting 58A can be engaged with the metal fitting 58B to reveal the locked state.
As shown in FIG. 4, the round bar frame member 59 protruding from the left side surface of the cover 55 is a locking member for the lock fitting 60 </ b> A of the vehicle body cover 60 that covers the drive unit such as the output pulley 36.

図4及び図5に示すように、支持フレーム48は走行機体2の機体フレーム2Aに対して着脱自在であるところから、チョッパー41を装備する仕様機種と装備しない機種とに機能分けが可能であり、チョッパー41をオプションとする使い方ができる。
そして、チョッパー41を備えない既存の機種に対しても、チョッパー41を後付けすることができる。
As shown in FIGS. 4 and 5, since the support frame 48 is detachable from the body frame 2A of the traveling body 2, the function can be divided into a specification model equipped with the chopper 41 and a model not equipped. The chopper 41 can be used as an option.
Further, the chopper 41 can be retrofitted to an existing model that does not include the chopper 41.

〔別実施形態〕
(1) 排ワラ処理装置の一例としてチョッパー41を例示したが、円盤カッターや結束装置等を排ワラ処理装置として含めてもよい。
(2) 排ワラ処理装置の開放方向としては、左右方向だけでなく上下方向であってもよく、カバー55の開放方向を左右方向に設定してもよい。
(3) 穀粒貯留装置9としては、アンローダを備えないグレンホッパ型のものであってもよい。
[Another embodiment]
(1) Although the chopper 41 is illustrated as an example of the waste straw processing apparatus, a disk cutter, a bundling device, or the like may be included as the waste straw processing apparatus.
(2) The opening direction of the waste straw processing apparatus may be the vertical direction as well as the left-right direction, and the opening direction of the cover 55 may be set to the left-right direction.
(3) The grain storage device 9 may be of the Glen Hopper type without an unloader.
