【００２２】 このとき、固定刃７は、それの支持台８０を、図１１に示しているように、回 転刃５の刃縁の傾斜方向と逆向きに対応する角度で傾斜するように装設しておく ことで、該固定刃７の刃縁が、回転刃５の刃縁と対応する角度で逆向きに傾斜す るようにしてあって、これにより、直刃状の回転刃５の刃縁と直刃状の固定刃７ の刃縁とが、それらの長手方向の各部において略同一の間隔を保持してすり合う ようにしてある。At this time, the fixed blade 7 is mounted so that its support base 80 is inclined at an angle corresponding to the direction opposite to the inclination direction of the blade edge of the rotating blade 5, as shown in FIG. By installing the fixed blade 7, the blade edge of the fixed blade 7 is tilted in the opposite direction at an angle corresponding to the blade edge of the rotary blade 5, whereby the rotary blade 5 of the straight blade shape is formed. The blade edge and the blade edge of the straight blade-shaped fixed blade 7 are rubbed with each other at substantially the same intervals in their respective longitudinal portions.
【００２３】 しかして、刃合わせの調整を終えたところで、セットボルト４７を強く締め込 み、ブロックＢを刃物取付金４に一体的に固着する。Then, when the adjustment of the blade alignment is completed, the set bolt 47 is strongly tightened to integrally fix the block B to the blade mounting metal 4.
【００２４】 これにより、刃物取付金４に設けた回転刃５の刃物取付座ｂは、締付金具９を 外して、そこに回転刃５の刃身５ａを嵌合して締付金具９により回転刃５を保持 せしめることで、その回転刃５の刃縁が固定刃７の刃縁にすり合う所定の回転軌 跡をもって回動するように位置決めするようになる。従って、一度刃合わせの調 整を行なった後は、締付金具９の装脱により回転刃５を新たな回転刃５と交換す ることで刃合わせが行なわれるようになる。As a result, the blade mounting seat b of the rotary blade 5 provided on the blade mounting metal 4 is detached from the tightening fitting 9, and the blade body 5a of the rotary blade 5 is fitted there, so that the tightening fitting 9 is used. By holding the rotary blade 5, the blade edge of the rotary blade 5 is positioned so as to rotate with a predetermined rotation track in which the blade edge rubs against the blade edge of the fixed blade 7. Therefore, after adjusting the blade alignment once, the rotary blade 5 is replaced with a new rotary blade 5 by mounting and dismounting the tightening fitting 9, so that the blade alignment can be performed.

以上説明したように本考案によるシリンダ型の農用カッターにおける切截機構 の刃合わせ調整装置は、撓曲自在の薄手の帯板状に形成した回転刃５を、主軸３ にボス部４０を嵌装して装着した刃物取付金４に組付け装着するに際し、刃物取 付金４にはそれの外端側に側面視でボス部４０の接線方向と平行する平らな台面 ４２０を形成しておいて、この台面４２０に前後方向に変位調節自在に組付けら れる摺動板４６を別に形成し、この摺動板４６の前縁に形設した刃物取付座ｂに 前記薄手の帯板状の回転刃５を嵌合して、その上から締付金具９を被せ締付ボル ト９１により閉じ合わせることで、摺動板４６と締付金具９と回転刃５とが一体 的に結合した摺動板４６を主体とするブロックＢを組立て、この回転刃５を保持 するブロックＢを、前記刃物取付金４の外端側に形成した台面４２０上に、前後 方向の変位調節自在に組付け、そのブロックＢを刃物取付金４の前記台面４２０ の後縁側に配設した調節ねじ４５・４５により変位調節することで、回転刃５と 固定刃７との刃合わせの調整を行なうようにしているのだから、回転刃５を組付 け保持せしめたブロックＢを、主軸３に装着した刃物取付金４の外端側に設けた 台面４２０上にセットボルト４７…により仮とじした状態において、調節ねじ４ ５・４５の回動によりブロックＢごと回転刃５を動かすことによって、この刃合 わせ調整が簡単に行なえるようになる。 As described above, the blade alignment adjusting device of the cutting mechanism in the cylinder type agricultural cutter according to the present invention is such that the rotary blade 5 formed in the shape of a flexible thin strip plate is fitted with the boss portion 40 on the main shaft 3. When assembled and attached to the blade mounting metal 4 that has been mounted in advance, the blade mounting metal 4 has a flat base surface 420 formed on its outer end side in parallel with the tangential direction of the boss portion 40 in a side view. A slide plate 46 is separately formed on the base surface 420 so as to be adjustable in displacement in the front-rear direction, and is attached to a blade mounting seat b formed at the front edge of the slide plate 46 to rotate the thin strip plate. By fitting the blade 5 and covering the tightening metal fitting 9 from above, and closing them with the tightening bolt 91, the sliding plate 46, the tightening metal 9 and the rotary blade 5 are integrally combined and slid. A block B having a plate 46 as a main body is assembled to hold the rotary blade 5. , An adjusting screw 45 which is mounted on a base surface 420 formed on the outer end side of the blade mounting metal 4 so that the displacement in the front-rear direction can be adjusted, and the block B is arranged on the rear edge side of the base surface 420 of the blade mounting metal 4. Since the adjustment of the blade alignment between the rotary blade 5 and the fixed blade 7 is performed by adjusting the displacement by 45, the block B with the rotary blade 5 assembled and held is attached to the spindle 3. By moving the rotary blade 5 together with the block B by rotating the adjusting screws 45 and 45 while the set bolts 47 are temporarily bound on the table surface 420 provided on the outer end side of the blade mounting metal 4, this blade fitting is performed. The adjustment can be easily performed.
【００２６】 そして、一たん刃合わせの調整を終えて、ブロックＢを刃物取付金４の台面４ ２０上に固定した後は、回転刃５が摩耗した刃合わせに狂いが生じてきたときに 、締付金具９を外して回転刃５を刃物取付座ｂから外し、新しい回転刃５に替え て刃物取付座ｂにセットし、締付金具９を閉じ合わせることで、回転刃５と固定 刃７との刃合わせが行なえるようになって、使用により回転刃５が摩耗してきた ときの対処が回転刃５を交換することで簡単に行なえるようになる。After the adjustment of the blade alignment is completed and the block B is fixed on the base surface 420 of the blade attachment metal 4, when the rotary blade 5 is worn out and the alignment of the blades becomes incorrect, Remove the tightening bracket 9 to remove the rotary blade 5 from the blade mounting seat b, set a new rotary blade 5 on the blade mounting seat b, and close the tightening bracket 9 to close the rotary blade 5 and the fixed blade 7. The blades can be aligned with each other, and when the rotary blade 5 becomes worn due to use, it can be easily dealt with by replacing the rotary blade 5.
