〔産業上の利用分野〕
この発明は、コンバインにおける第二刈取装置に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a second reaping device in a combine harvester.
従来より、コンバインの刈取部には前側の第一刈刃と後
側の第二刈刃とを設けたものがある。BACKGROUND ART Conventionally, some combine harvesters have a reaping section that is provided with a first cutting blade on the front side and a second cutting blade on the rear side.
これは、第一刈刃によって圃場に植立する軸枠の穂先部
を刈取って収穫し、刈残された穀稈の株元部を第二刈刃
で刈払うものである。In this method, a first cutting blade is used to cut and harvest the tip of a shaft frame planted in a field, and a second cutting blade is used to cut off the base of the grain culm that remains uncut.
従来技術のものは、第一刈刃によって刈残された刈残穀
稈を第二刈刃で刈払うとき、刈残穀稈の姿勢が第二刈刃
によって刈り払い易い姿勢でないと容易に刈払うことが
できない。多くの場合、刈残穀稈の姿勢は良好とはいえ
ず、このために第二刈刃よる刈払いの失敗が起こり、別
線が乱れてしまう欠点があった。In the prior art, when the uncut grain culm left behind by the first cutting blade is mowed by the second cutting blade, the uncut grain culm is easily mown if the posture of the uncut grain culm is not in a position that makes it easy to cut by the second cutting blade. I can't pay. In many cases, the posture of the unharvested grain culm is not good, and as a result, the second cutting blade fails to cut the grass, resulting in a disorganized separation line.
また、第二刈刃によって刈払われた穀稈が、この第二刈
刃の上に堆積し、第二刈刃の切断能力を低下させる原因
となっていた。Moreover, the grain culms cut off by the second cutting blade accumulate on the second cutting blade, causing a reduction in the cutting ability of the second cutting blade.
［３１題を解決するための手段］
この発明は前述の如き課題を解決するために、以下の様
な技術適手段を講する。[Means for Solving the 31 Problems] In order to solve the above-mentioned problems, the present invention takes the following technical measures.
すなわち、走行装置１の上方に設けた脱穀装置２と、
該脱穀装置２の前方に上下動自在に設けた刈取部３と、
該刈取部３の前側に設けた第一刈刃４、及び後側に設け
た第二刈刃５と、
該第二刈刃５の上方に位置し、左右方向の回転軸芯を有
する回転体６とを設け、
該回転体６は、これが回転すると、前記第一刈刃４によ
って刈残された穀稈の上部を後方へ向けて押圧するよう
に構成したことを特徴とするコンバインにおける第二刈
取装置としたものである。That is, a threshing device 2 provided above the traveling device 1, a reaping section 3 provided vertically movably in front of the threshing device 2, a first cutting blade 4 provided on the front side of the reaping section 3, and a rear. A second cutting blade 5 is provided on the side, and a rotating body 6 is provided above the second cutting blade 5 and has a rotation axis in the left and right direction. This is a second reaping device for a combine harvester, characterized in that it is configured to press the upper part of the grain culm left uncut by the cutting blade 4 toward the rear.
走行装置１を駆動して機体を前進させ、第一刈刃４によ
って圃場に植立する穀稈の穂先部を刈取り、脱穀処理し
て収穫する。そして圃場に刈残された穀稈の株元部を第
二刈刃５で切断する。このとき、第二刈刃５上方に設け
た回転体６の回転によって刈残穀稈を後方へ押圧するの
で、刈残穀稈は第二刈刃５によって切断し易い姿勢にな
り第二刈刃５に押し付けられる。これによって第二刈刃
５による刈残穀稈の刈払いは円滑に行われ、別路も滑ら
かになる。The traveling device 1 is driven to move the machine forward, and the first cutting blade 4 cuts the tip of the grain culm to be planted in the field, and the crop is threshed and harvested. Then, the stock base of the grain culm left in the field is cut off with the second cutting blade 5. At this time, the rotation of the rotating body 6 provided above the second cutting blade 5 pushes the uncut grain culm backward, so the uncut grain culm is placed in a position where it can be easily cut by the second cutting blade 5, and the second cutting blade Pushed to 5. As a result, the uncut grain culm can be smoothly mowed down by the second cutting blade 5, and the separate route can also be made smooth.
また、第二刈刃５によって切断された穀稈は回転体６の
回転によって第二刈刃５の後方へ送り出されるため、第
二刈刃５上部へ堆積することがない。この結果、第二刈
刃５の切断能力を低下させず、円滑な作業を行うことが
できる。Moreover, since the grain culms cut by the second cutting blade 5 are sent out to the rear of the second cutting blade 5 by the rotation of the rotary body 6, they do not accumulate on the upper part of the second cutting blade 5. As a result, smooth work can be performed without reducing the cutting ability of the second cutting blade 5.

力を低下させず、円滑な作業を行うことができる。When the machine is moved further forward, the second cutting blade 5 located behind the first cutting blade 4 cuts off the grain remaining in the field from the base of the plant. The first blade is forcibly pushed toward the second cutting blade 5 by the pressing wing piece 43 on the outer peripheral surface of the blade. Therefore, the uncut grain culms are brought into a good posture by the rotation of the rotating body 6, and mowing by the second cutting blade 5 is facilitated. Further, the culm cut by the second cutting blade 5 is sent out behind the second cutting blade 5 by the pressing wing piece 43 of the rotating body 6 and discharged to the field. This prevents grain culms from accumulating on the second cutting blade 5, allowing smooth work to be performed without reducing the cutting ability of the second cutting blade 5.
