【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、植立茎稈を引起すと共に刈取り装置に掻込む
ように、左右水平方向に沿う回転軸芯周りに回転する駆
動回転リールを設けたコンバインの回転リール構造に関
する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention provides a drive rotation reel that rotates around a rotation axis along the horizontal direction so as to raise a planting culm and scrape it into a cutting device. The present invention relates to the structure of a rotating combine reel provided.
従来、駆動回転リールに備えた全ての茎稈係止爪が、例
えば実開昭62−116634号公報で示されるように、正面視
において垂直下方に突出するように取り付けられてい
た。Conventionally, all the stem-claw engaging claws provided on the drive rotation reel have been attached so as to project vertically downward when viewed from the front, as shown, for example, in Japanese Utility Model Laid-Open No. 62-116634.
上記従来技術では、倒伏した茎稈を刈取る場合におい
て、完全追い刈り又は完全向い刈りのとき、つまり、茎
稈の倒伏方向と茎稈係止爪の突出方向とが同一になると
き、茎稈係止爪が茎稈に沿ってすり抜けてしまい茎稈を
確実に引起すことができなくなることがあった。In the above-mentioned conventional technique, in the case of mowing fallen stalks, at the time of complete follow-up or complete mowing, that is, when the fall direction of the stalks and the protruding direction of the stalk stalks are the same, the stalks are In some cases, the locking claws slipped along the culms and it was not possible to reliably raise the culms.
そのようなときには、機体をジグザグに運転することで
茎稈係止爪の茎稈に対する引掛かりを良くすることもで
きるが、操縦が煩わしく疲労しやすいものであった。In such a case, by operating the machine in a zigzag manner, it is possible to improve the catching of the stem-culm locking claws with respect to the stems, but the operation is troublesome and tired easily.
本考案の目的は、完全追い刈り又は完全向い刈り時にお
いても機体を直進させながら倒伏茎稈を確実良好に引起
すことができる、コンバインの回転リール構造を提供す
ることにある。An object of the present invention is to provide a combine reel rotating reel structure capable of surely and properly raising the fallen stem culm while advancing the machine body even during complete mowing or complete mowing.
本考案にかかるコンバインの回転リール構造は、上記目
的を達成するために、前記駆動回転リールにその回転軸
心に沿って複数本の爪取付部を設けてあるとともに、前

同一の爪取付部では各茎稈係止爪を、互に同一方向に向
いた姿勢で設け、さらに、相隣る爪取付部同士では茎稈
係止爪を、その傾斜角が互に異なる状態で設けてあるこ
とを特徴構成とする。In order to achieve the above-mentioned object, the combine rotary reel structure according to the present invention is provided with a plurality of pawl mounting portions along the rotational axis of the drive rotary reel, and each pawl mounting portion includes: A plurality of stem-claw locking claws arranged side by side on the left and right are provided so that they can be fixedly mounted in a posture inclined to the right or left
In the same claw mounting part, each stem culm locking claw is provided in a posture in which they are oriented in the same direction as each other, and the claw mounting parts adjacent to each other have stalk and culm locking claws whose inclination angles are different from each other. Is provided as a characteristic configuration.
かかる特徴構成による作用及び効果は次の通りである。The operation and effect of this characteristic configuration are as follows.
すなわち、茎稈係止爪は同一の爪取付部において同一方
向に向いた姿勢で取付られ、かつ、相隣る爪取付部同士
の茎稈係止爪の傾斜角を異ならせる状態で茎稈係止爪を
設けてあるから、完全追い刈りあるいは完全向い刈りの

止爪は固定状態で設けてあるから、茎稈に対して係止や
梳き上げを行う位置で特定の傾斜姿勢にカム機構等で切
り換えるものに比べて構造簡単で故障しにくいものとな
る。That is, the stem-culm locking claws are mounted in the same claw mounting part in the same orientation, and the stem-culm locking claws of adjacent claw mounting parts are different in inclination angle. Since the pawl is provided, the fall direction of the culm and the protruding direction of the culm locking claw do not become the same even during complete mowing or full cutting, and the culm locking claw prevents It is possible to lock and pick up the stems almost uniformly in the left-right direction so that no shade occurs in the portion where the locking and pulling-up action of No. 1 and the other portion do not work. Furthermore, since the stem culm locking claws are provided in a fixed state, the structure is simpler and less prone to failure as compared to a structure in which a cam mechanism or the like switches to a specific tilted position at the position where the stems are locked or pulled up. Will be things.
また、茎稈係止爪の突出方向が相隣るものでは異なるの
で、茎稈係止爪の突出方向が茎稈の倒伏方向と同一にな
ることはない。Further, since the protruding directions of the stem-culm locking claws are different from each other, the protruding direction of the stem-culm locking claws is not the same as the fall direction of the stems.
従って、茎稈の倒伏方向に拘らず直進走行のままで茎稈
を確実に引起すことができることになり、煩わしいジグ
ザグ運転をする必要がなくなって操作性を高めることが
できるとともに、茎稈係止爪の爪取付部に対する姿勢を
リールの所定回転位相で変更しなくても良いから、構造
的に簡単なものとなりコスト低下を図ることもできるに
至った。Therefore, regardless of the fall direction of the stalk, the stalk can be surely raised while traveling straight, and it is not necessary to perform a troublesome zigzag operation, and the operability can be improved and the stalk can be locked. Since the attitude of the claw with respect to the claw mounting portion does not have to be changed at a predetermined rotation phase of the reel, it is structurally simple and the cost can be reduced.
