【考案の詳細な説明】
本考案は、多数枚の回転円形刃などを備えた回転軸を、
カッターケースに対して着脱交換可能となした排稈切断
処理装置に関する。[Detailed description of the invention] This invention uses a rotating shaft equipped with a large number of rotating circular blades, etc.
The present invention relates to a culm cutting device that can be attached to and removed from a cutter case.
最近コンバインの大型化と性能の向上によりコンバイン
の一日の作業量が大巾に増大し、そのために脱穀済排稈
を細断するカッター刃の研磨や交換などの頻度が高くな
っている。Recently, as combine harvesters have become larger and their performance has improved, the daily workload of combine harvesters has increased significantly, and as a result, the cutter blades that shred the threshed culm have to be polished and replaced more frequently.
しかし刃の研磨や交換を行うにしても、従来ではカッタ
ー機構全体をコンバイン本体より取外して行っているが
、コンバインが大型なものは、カッターの取付位置が高
く加えて重量も重いことから、■人で交換を行うことが
出来ず、更に交換に長時間を要する欠点がみられた。However, in the past, the entire cutter mechanism had to be removed from the combine body in order to sharpen or replace the blade. Another disadvantage was that it could not be replaced by a person, and it took a long time to replace it.
本考案は、このようなディスク型カッターの少くとも高
速回転軸を、合理的に且つ迅速に脱せしめるようにした
ことを目的とするものである。The object of the present invention is to enable at least the high-speed rotating shaft of such a disc cutter to be removed rationally and quickly.

ある。In the figure, 31 is a large-diameter gear provided at the end of the drive shaft 13 connected to the low-speed rotating shaft 2 and meshed with the small-diameter gear 23,
This relationship causes a difference in height between the two rotating shafts 2 and 3.

り除き、高速回転軸３と無関係とする。Next, to explain the replacement operation of the high-speed rotating shaft 3, first rotate the nut member 19 and remove its screw 20 from the screw 15 provided on the stopper member 16, then remove the bolt and nut 29 of the other bearing body 30. The bearing body 30 of the lever is removed to make it irrelevant to the high-speed rotating shaft 3.
この状態で図において最右端にある排稈巻付き防止バイ
ブロをカッターケース１の大径孔２Ｂからケース外にと
り出す。In this state, take out the culm wrapping prevention vibro located at the rightmost end in the figure from the large diameter hole 2B of the cutter case 1 to the outside of the case.

１１と溝部９との嵌合関係が解かれる。In this state, move the high-speed rotation shaft 3 to the right and the high-speed rotation circular blade 11
The connecting shaft portion 12 is removed from the shaft hole 14 of the drive shaft 13 until the side surface thereof abuts the inner surface of the flange portion 8 of the dish-shaped disk 7, that is, by a length of 1°, and then the connecting shaft portion 12 is removed. When the side surface comes into contact with the inner surface of the recess 18, that is, when it moves in the direction opposite to the low-speed rotary shaft 2 by a distance of 13, the fitted relationship between the high-speed rotary circular blade 11 and the groove 9 is released.
次に高速回転軸３全体を右方へ移動することによりこの
軸は完全にフリーとなり、全体を斜めに向きを変えれば
カッターケース１から外部にとり出せる。Next, by moving the entire high-speed rotating shaft 3 to the right, this shaft becomes completely free, and by changing the direction of the entire shaft diagonally, it can be taken out from the cutter case 1.
そして上記と逆の操作で新しい高速回転円形刃をとりつ
けた別の高速回転軸をとりつけるものである。Then, by reversing the above procedure, attach another high-speed rotating shaft with a new high-speed rotating circular blade attached.
また低速回転軸２は単独でとり外すことがないので、そ
の着脱は高速回転軸の交換に比べて簡単に行える。Furthermore, since the low-speed rotating shaft 2 does not have to be removed alone, its attachment and detachment can be performed more easily than replacing the high-speed rotating shaft.
このように本考案によれば、ディスク型カッターにおけ
