つており、挟扼ガイド杆5の収納・引出しの為の
移動方向が固定ガイド杆5aの嵌合孔の方向とず
れて、収納・引出し時に係合しないように構成し
ている。 The rear end of the pincer guide rod 5 is pivotally supported by a rotating arm 6 via a spring plate 5c. The rotating direction of the rotating arm 6 is approximately along the protruding direction of the straw removal chain A, and the moving direction for storing and drawing out the pinching guide rod 5 is shifted from the direction of the fitting hole of the fixed guide rod 5a. , so that it does not engage when being stored or drawn out.
更に連動リンク7aは切換カバー1の支持軸8
にアーム7cを介して枢結されており、切換カバ
ー1は弧状に回動するのでリンク7aとロツド7

ないようにしている。 Further, the interlocking link 7a is connected to the support shaft 8 of the switching cover 1.
The switching cover 1 rotates in an arc, so that the link 7a and the rod 7
It is absorbed by the elasticity of b so that it does not affect the rotating arm 6.
故に回動アーム6には回動軸6aを中心に水平
に回動するので、挟扼ガイド杆5も水平に前後動
して、固定ガイド杆5a内に収納又は引出される
のである。 Therefore, since the rotating arm 6 rotates horizontally around the rotating shaft 6a, the pincer guide rod 5 also moves horizontally back and forth, and is housed in or pulled out within the fixed guide rod 5a.
30はカツターフレームである。 30 is a cutter frame.

ある。 Further, 24 is a focusing device, 25 is a focusing guide plate, 2
Reference numeral 6 denotes a focusing guide rod, as shown in FIG. 1, which is protruded during focusing work and folded during cutter work.
(ヘ) 考案の効果
本考案は以上の如く構成したので次の様な効果
を奏するものである。(F) Effects of the invention Since the invention is constructed as described above, it has the following effects.
第1に、従来技術である実公昭59−17154号公
報に記載の技術においては、挟扼ガイド杆の部分
を切換カバーと兼用して、大きく上下に回動する
必要があるので、切換操作力が大きくなり、確実
な切換が出来ないという不具合いがあつたのであ
る。 Firstly, in the conventional technology described in Japanese Utility Model Publication No. 59-17154, the pincer guide rod also serves as a switching cover, and it is necessary to rotate it up and down considerably, so the switching operation is required. This caused a problem in that the amount of noise increased and reliable switching was not possible.
これに対して、本考案は切換カバーと挟扼ガイ
ド杆5は、別の構成として、どちらも水平方向に
摺動することにより、切断と非切断の切換を可能
としたので、切換に要する操作が軽く行えるよう
になつたのである。 In contrast, in the present invention, the switching cover and the pinching guide rod 5 have separate structures, and both slide in the horizontal direction, making it possible to switch between cutting and non-cutting, so the operation required for switching is Now I can do it easily.
第2に、従来技術である特開昭54−66247号公

開閉カバーの開閉と集稈装置を連動しているが、
挟扼ガイド杆との連動がなされていないので、そ
の都度オペレーターが、カツターカバー内に手を
入れて、挟扼ガイド杆を引き出すという作業が必
要だつたのである。 Second, in the prior art Japanese Patent Application Laid-Open No. 54-66247, the power connection/disconnection of the straw cutting device, the opening/closing of the upper opening/closing cover, and the culm collecting device are linked.
Since there was no linkage with the pincer guide rod, the operator had to put his hand inside the cutter cover and pull out the pincer guide rod each time.
本考案は、上部開閉カバー2と切換カバー1の
切換に連動して、挟扼ガイド杆5の前後伸縮を同
時に行えるように構成したので、オペレーターが
カツターカバー27の内部に手を入れる必要が無
くなつたのである。 The present invention is configured so that the pincer guide rod 5 can be extended and contracted back and forth at the same time in conjunction with switching between the upper opening/closing cover 2 and the switching cover 1, so the operator does not have to put his hand inside the cutter cover 27. It was gone.
第3に、上部開閉カバー2の切換把手2aを設
けて、切断と非切断の切換操作を可能としたの
で、別に切換レバーを設ける必要がなく、確実な
操作で切換を行うことが可能となつたのである。 Thirdly, since the switching handle 2a of the upper opening/closing cover 2 is provided to enable switching between cutting and non-cutting, there is no need to provide a separate switching lever, and switching can be performed with reliable operation. It was.
