本発明は材料をドラムの走間で切断するロータリドラム
型クロップシャに係り、特に刃物寿命の向上に好適なり
ロップシャに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Cutting Machine] The present invention relates to a rotary drum type crop shear for cutting materials between the runs of a drum, and particularly to a crop shear suitable for improving the life of the blade.
第１図および第２図にロータリドラム型クロップシャの
概要構造を示す。Figures 1 and 2 show the general structure of a rotary drum type crop shear.
中間ハウジング１には対峙する１対の同一形状のドラム
２，３の両端部が枢支され、ドラム２Ｉ３には刃物４が
保持される。中間ハウジング１は固定ハウジング５に支
持され、図示しない固定平膜により固定される。Both ends of a pair of opposing drums 2 and 3 having the same shape are pivotally supported on the intermediate housing 1, and a cutter 4 is held on the drum 2I3. The intermediate housing 1 is supported by a fixed housing 5 and fixed by a fixed flat membrane (not shown).

を支持するためのものである。Rotation from an electric motor (not shown) is transmitted to the intermediate shaft 8 via the reducer 7. A drive shaft 9 is slidably engaged within the intermediate shaft 8 and transmits the rotation of the intermediate shaft 8 to a distribution gear 10 to rotate the drums 2, 3 in opposite directions and at the same rotational speed. A material (not shown) is inserted between the drums 2 and 3 and cut by the cutter 4. The intermediate housing 1 is held in the state shown in the figure during crop shear operation such as cutting, but when the cutter 4 is replaced, etc. , it is pulled out from inside the fixed housing 5. Since the drums 2.3 are pivotally supported on the intermediate housing 1 as described above, the drums 2, 3, distribution gear 10 and drive shaft 9 are pulled out together with the intermediate housing 1. Therefore, the fifth
As shown in the figure, the insertion part of the drive shaft 9 inserted into the intermediate shaft 8 is formed into an oval shape with both ends cut off, so that it can slide and transmit rotation (of course, it is splined). (It may be something like a fitting) 0 Note that the cylinder 1 in Fig. 1
1 is the intermediate shaft 8 when the drive shaft 9 is pulled out from the intermediate shaft 8.
It is intended to support the

には横幅すの幅端に係合する刃物４の部分りに力が加わ
り、その部分りが他の部分に較べ早く傷む。一方、材料
１２の横幅すは一定の場合が多い。To cut the material 12 (shown in FIG. 4), which is the material to be cut, the material 12 is inserted between the drums 2 and 6 and cut by the blade 4 as described above, but the width of the side slope 12 is constant. In this case, force is applied to the part of the cutter 4 that engages with the width end of the width cutter, and that part gets damaged more quickly than other parts. On the other hand, the width of the material 12 is often constant.
従って、他の部分が傷ついていないにも拘らず、部分り
の損傷によル刃物４全体を刃替えする必要が生じ、刃物
４の寿、命が短くなると共に、刃替頻度が多くなシ、作
業効率が低下する欠点が生ずる。Therefore, even if other parts are not damaged, damage to one part of the blade necessitates replacing the entire blade 4, shortening the lifespan of the blade 4, and requiring frequent blade replacement. , there is a disadvantage that work efficiency is reduced.
〔発明の目的〕
本発明は上記の欠点を解決すべく創案されたものでアシ
