Description
【０００１】[0001]
本考案はコンバイン、バインダー等に装備されるバリカン型刈刃に係り、この 刈刃を駆動する駒構造に関する。 The present invention relates to a clipper-type cutting blade mounted on a combine, a binder, etc., and relates to a bridge structure for driving the cutting blade.
【０００２】[0002]
コンバイン、バインダー等に採用されるバリカン型刈刃は、固定刃となる下刃 と可動刃となる上刃とから構成され、この上刃は、上刃に固定したナイフヘツド が支点軸を中心にして揺動するベルクランクの一端に回動自在に枢支された円筒 状の駒により左右に往復動されることによつて、左右に往復移動するようになつ ている。 The hair clipper-type cutting blade used for combine and binder is composed of a lower blade that serves as a fixed blade and an upper blade that serves as a movable blade.This upper blade has a knife head fixed to the upper blade centered on a fulcrum shaft. It is adapted to reciprocate left and right by being reciprocated left and right by a cylindrical piece pivotally supported at one end of an oscillating bell crank.
【０００３】 殊に多条刈りとなるコンバイン等の刈刃は、長さも長くなり高負荷となる上に さらに高速運転されるので、駒の左右両側に形成した平坦面をナイフヘツドに開 口したＵの字状の案内孔に嵌合することにより十分な面圧が保持され、高負荷、 高速運転に対する耐久性の向上が図られている。Particularly, since a cutting blade such as a combine harvester for multi-row cutting has a long length and a high load, and is further operated at a high speed, a flat surface formed on both left and right sides of the piece is opened in a knife head. Sufficient surface pressure is maintained by fitting in the letter-shaped guide hole, and the durability against high load and high speed operation is improved.
【０００４】[0004]
ところで、ベルクランク側に固定される縦軸と、この縦軸に回動自在に嵌合す る筒状の駒との合面には、潤滑油を貯留するための「油だまり」がないので、注 油しても外部に流れ易い上に藁屑等が両者間に侵入することもあつて、縦軸と駒 との合面が早期に摩耗して非常に高い騒音を発生するようになり、依然として駒 および縦軸の耐久性が低いという問題点があつた。 By the way, there is no "puddle" for storing lubricating oil on the mating surface of the vertical axis fixed to the bell crank side and the cylindrical piece rotatably fitted to this vertical axis. Even if lubrication is performed, it easily flows to the outside and straw debris and the like may enter between the two, causing the mating surface between the vertical axis and the bridge to wear early and generating extremely high noise. However, there was still a problem that the durability of the piece and the vertical axis was low.
【０００５】 そこで、本考案は上述した問題点を解消すべく創案されたもので、縦軸と駒と の合面における早期摩耗を阻止し、駒および縦軸の耐久性を向上できる刈刃駆動 用の駒構造を提供することを目的として実施するものである。Therefore, the present invention was devised to solve the above-mentioned problems, and it prevents cutting of wear at the mating surface between the vertical axis and the piece and improves the durability of the piece and the vertical axis. The present invention is carried out for the purpose of providing a piece structure for use.

上記目的を達成する本考案は、ナイフヘツド６の案内孔５にベルクランク１０ 側の駒１３を嵌合するようにした刈刃において、縦軸１９に設けた上部から油が 供給できる油路２０には螺子２２を穿設すると共に、縦軸１９と駒１３との合面 には上記油路２０に連通する油だまり部２１と、この油だまり部２１の上下に位 置するオイルシール部２４を夫々設け、駒１３の上下動を制止する座金２５を上 記螺子２２に螺合する取付ボルト２３により縦軸１９の上端面に着脱自在に固定 したものである。 The present invention that achieves the above-mentioned object is a cutting blade in which the bell crank 10 side piece 13 is fitted in the guide hole 5 of the knife head 6, and an oil passage 20 through which oil can be supplied from the upper portion provided on the vertical axis 19 is provided. A screw 22 is bored, and an oil sump portion 21 communicating with the oil passage 20 and an oil seal portion 24 positioned above and below the oil sump portion 21 are formed on the mating surface between the vertical axis 19 and the bridge 13. A washer 25, which is provided in each case, for stopping the vertical movement of the piece 13, is detachably fixed to the upper end surface of the vertical axis 19 by a mounting bolt 23 screwed to the screw 22.
【０００７】[0007]
したがつて、ナイフヘツド６の案内孔５にベルクランク１０側の駒１３を嵌合 するようにしたバリカン型刈刃１にあつても、駒分解用の取付ボルト２３を取り 外すことにより上部が開放された縦軸１９側の油路２０を利用して油が油だまり 部２１に供給される。この油だまり部２１に貯留された油は、取付ボルト２３の 締付けによる油路２０の密閉と、油だまり部２１の上下両側に設けたオイルシー ル部２４とにより完全に密封され、外部に流出することがないので、駒１３と縦 軸１９との合面には異物侵入阻止に併せて長期にわたる油潤滑を行い得る。 Therefore, even with the clipper-type cutting blade 1 in which the piece 13 on the side of the bell crank 10 is fitted in the guide hole 5 of the knife head 6, the upper part is opened by removing the mounting bolt 23 for disassembling the piece. Oil is supplied to the oil sump 21 by utilizing the oil passage 20 on the side of the vertical axis 19 that is formed. The oil stored in the oil sump 21 is completely sealed by the tightness of the oil passage 20 by tightening the mounting bolt 23 and the oil seals 24 provided on the upper and lower sides of the oil sump 21, and then flows out to the outside. Therefore, the mating surface of the bridge 13 and the vertical shaft 19 can be lubricated for a long period of time in addition to preventing foreign matter from entering.
