Description
【考案の詳細な説明】 〔産業上の利用分野〕 本考案はコンバイン等の刈取部に備えられて、倒伏して
いる茎稈を引き起こす茎稈引起し装置に関する。[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a stem culm raising device which is provided in a harvesting part of a combine or the like and causes fallen stem culms.
前述のような茎稈引起し装置では、例えば実開昭59−16
331号公報に開示されているように、起立姿勢に在る引
起し爪が引起しケース内に引き込まれる箇所に、緩衝部
材を設けているものがある。これにより、引起し爪の先
端側が緩衝部材に接当して、引起し爪が倒伏格納姿勢に
案内されながら引起しケース内に引き込まれて行く。In the stem culm raising device as described above, for example, in Japanese Utility Model Laid-Open No. 59-16
As disclosed in Japanese Patent No. 331, a cushioning member is provided at a position where a raising claw in an upright posture is pulled up and pulled into a case. As a result, the tip end side of the raising claw comes into contact with the cushioning member, and the raising claw is pulled into the case while being guided in the collapsed storage posture.
前述のような構造であると、引起し爪が引起しケース内
に引き込まれる度に、引起し爪が緩衝部材に衝突するこ
とになるので、連続的な衝突音が生ずることになる。With the above-described structure, the raising claws collide with the cushioning member every time the raising claws are pulled up and drawn into the case, so that a continuous collision noise is generated.
そして、引起し爪はチェーン上部のローラー部分におい
て、振り回されるようにして引き込まれて行くので、比
較的高速となる引起し爪の先端側が緩衝部材に衝突する
ことになり、前述の衝突音が比較的大きなものとなって
いる。Then, since the raising claws are drawn in by being swung around in the roller portion on the upper part of the chain, the tip side of the raising claws at a relatively high speed collides with the cushioning member, and the above-mentioned collision noise is compared. It is a big thing.
本考案は茎稈引起し装置において、引起し爪が引起しケ
ース内に引き込まれる際の衝突音を抑えることを目的と
している。An object of the present invention is to suppress the collision noise when the raising claw is raised and pulled into the case in the stem culm raising device.
本考案の特徴は以上のような茎稈引起し装置において、
次のように構成することにある。The feature of the present invention is that in the stem culm raising device as described above,
It consists in configuring as follows.
緩衝部材が引起し爪に接当する前に、引起し爪の基部に
おけるチェーンへの枢着点近傍部分に接当して、引起し
爪を倒伏姿勢側に姿勢変化させる接当部を備えた補助緩
衝部材を、引起しケース内に設けてある。Before the cushioning member abuts against the raising claw, the abutment portion is provided to abut on a portion of the base of the raising claw near the pivot point of the chain to change the posture of the raising claw to the lying posture side. An auxiliary cushioning member is provided inside the raised case.
（ｉ） 本考案のような補助緩衝部材を設けると、引起し爪は緩
衝部材に衝突する前に、補助緩衝部材によりある程度倒
されたような状態となる。(I) When the auxiliary cushioning member according to the present invention is provided, the raising claw is in a state of being tilted to some extent by the auxiliary cushioning member before colliding with the cushioning member.
これにより、完全に起立した状態で引起し爪の先端が緩
衝部材に衝突する場合に比べて、引起し爪がある程度倒
されていると引起し爪の先端の速度は低いものとなるの
で、引起し爪が緩衝部材に衝突する際の衝突音が小さく
なる。As a result, the speed of the tip of the raising claw becomes low when the raising claw is tilted to some extent, compared to the case where the tip of the raising claw collides with the cushioning member in the state of being completely raised. The collision noise when the nail collides with the cushioning member is reduced.
（ii） この場合、補助緩衝部材の接当部が引起し爪の基部にお
けるチェーンへの枢着点近傍部分に接当するようにして
おり、この部分の振り回し時の速度は引起し爪の先端の
速度よりも十分に小さいので、引起し爪が補助緩衝部材
の接当部に衝突する際の衝突音は十分に小さいものとな
る。(Ii) In this case, the abutment part of the auxiliary cushioning member abuts the part of the raising claw near the pivot point of the chain at the base of the raising claw, and the speed of swinging around this part is the tip of the raising claw. Since it is sufficiently smaller than the speed of, the collision noise when the raising claw collides with the contact portion of the auxiliary cushioning member is sufficiently small.
そして、引起しケース内に補助緩衝部材が設けられてい
るので、引起し爪が補助緩衝部材の接当部に衝突する際
の小さな衝突音も、引起しケースの外側に伝わり難い。Further, since the auxiliary cushioning member is provided inside the raising case, a small collision sound when the raising claw collides with the contact portion of the auxiliary cushioning member is hard to be transmitted to the outside of the raising case.
以上のように引起し爪が緩衝部材に衝突する際の衝突音
を抑え、補助緩衝部材の接当部が引起し爪の枢着点近傍
部分に接当する際の衝突音も小さく、且つ外側に伝わり
難くして、引起し爪の引起しケース内への引き込み時の
全体の衝突音（補助緩衝部材及び緩衝部材の衝突音の
和）を抑えることができた。As described above, the collision noise when the raising claw collides with the cushioning member is suppressed, and the collision noise when the abutment portion of the auxiliary cushioning member raises and abuts the portion near the pivot point of the claw is small, and the outside It was possible to suppress the entire collision sound (sum of collision sounds of the auxiliary cushioning member and the cushioning member) at the time of retracting the raising claw into the raising case.
又、補助緩衝部材により引起し爪が激しく緩衝部材に衝
突することが抑えられるので、緩衝部材の耐久性も向上
させることができた。Further, since the auxiliary cushioning member can prevent the raised claws from colliding with the cushioning member violently, the durability of the cushioning member can be improved.
以下、本考案の実施例である茎稈引起し装置について図
面に基づいて説明する。Hereinafter, a stem culm raising device according to an embodiment of the present invention will be described with reference to the drawings.

る。The pull-up claw (5) has an axis (P 1 ) with respect to the chain (4).
A standing rail provided in the case (1), which is pivotally connected around a pin (corresponding to a pivot point) and in which a foot portion (5a) (corresponding to a base portion) of a raising claw (5) is raised. By contacting with (6), the standing posture of the raising claw (5) is maintained, and the raising claw (5) is raised from the slit-like claw projecting movement opening (1a) extending from the driven roller (3) to the drive sprocket (2). The nail (5) is projected and the stem culm is raised. The inside (5c) of the foot (5a) of the raising claw (5) is formed into an arc surface, and it fits well with the outer peripheral edge (3a) of the driven roller (3), and the posture of the raising claw (5) I try not to attach it.

る。In the raising case (1), a rubber cushioning member (8) and a leaf spring auxiliary cushioning member (9) are attached to the upper ends of the slit-like claw projecting movement openings (1a).
As shown in FIG. 1, the movement of the raising claw (5) in this vicinity is caused by the raising claw (5) which has moved upward in the standing posture along the standing rail (6). When it comes off from the upper end of the, it will be slightly downward due to its own weight and inertia.

るようにしている。Then, when the raising claw (5) is hooked on the drive sprocket (2) and started to be swung, the raising claw (5) starts to return to the standing posture due to the centrifugal force. At that time, in the raising case (1), the upper side of the foot portion (5a) of the raising claw (5) is brought into contact with the tip of the auxiliary cushioning member (9) (corresponding to the contact portion), and the raising claw is formed. The posture of (5) is tilted to some extent, and then the tip end side of the raising claw (5) contacts the cushioning member (8), and the raising claw (5) is in a substantially lying posture. Further, the rubber member (10) is attached to the inner surface of the raising case (1), and the impact when the raising claw (5) turns around the drive sprocket (2) and collides with the inner surface of the case (1). Is trying to absorb.

ている。While the raising claw (5) is in the standing posture and causing the stem culm, it may bend downward due to the reaction force from the stem. When the pull-up claw (5) bends downward in this way, the root side of the pull-up claw (5) may swell and rub against the edge of the claw protrusion moving opening (1a).
As shown in the drawing, a notch (5b) is provided in the portion of the raising claw (5) that is rubbed against the edge on the base side so as not to swell.
