Description

この考案は、雑草等を刈払う刈払機に係るもので、より詳しくはナイロンコ−ド等を用いたコード型刈払機のコード保持装置に関するものである。   The present invention relates to a brush cutter for cutting weeds and the like, and more particularly to a cord holding device for a cord type brush cutter using a nylon cord or the like.

従来、回転軸に着脱自在に固着される円盤等の回転板体に対して、これの周辺に一定長の刈払い用の弾性コードを刈刃として突出させ、前記円盤の回転により前記弾性刈刃コードを前記円盤と一体に回転させて雑草などを刈払う刈払機について種々の技術が提案されている。また、前記弾性刈刃コードは比較的硬質の合成樹脂製コードやばね線材を用いて形成され、一定長が前記円盤の外周に臨むように、該円盤に強大な遠心力を受けるなどしても容易に抜けないように取り付けられている。   Conventionally, with respect to a rotating plate body such as a disk that is detachably fixed to a rotating shaft, an elastic cord for a certain length of cutting is projected as a cutting blade around the rotating plate body, and the elastic cutting blade is rotated by rotating the disk. Various techniques have been proposed for a brush cutter for cutting a weed or the like by rotating a cord integrally with the disk. Further, the elastic cutting blade cord may be formed using a relatively hard synthetic resin cord or a spring wire, and may receive a strong centrifugal force on the disk such that a certain length faces the outer periphery of the disk. It is attached so that it does not come off easily.

例えば、コード型刈払機のコード収納部材Bのコード保持機構としては、図4〜図6に示すようなものがある。図4においてはコード5の端部5aに結び目5bを作り、コード5の本体ケース外部への抜け出しを防止するものである。図5のものは、コード5の中央部5cをコード収納部材Bの筒状胴部外面26に設けたフック23に引掛けて、コード5を保持し該コード収納部材Bに巻回収納するものである(例えば、特許文献1参照。)。また図6は、コード収納部材Bの筒状胴部外面26に設けたコード保持部24の貫通孔25にコード5の端部5aをコード中央部5cが該コード保持部24に至るまで通し、該コード中央部5cでコード5を折り曲げ該コード5をコード収納部材Bに巻回収納するものである(例えば、特許文献2参照。)。

For example, as a cord holding mechanism of the cord storage member B of the cord type brush cutter, there are those shown in FIGS. In FIG. 4, a knot 5b is formed at the end 5a of the cord 5 to prevent the cord 5 from slipping out of the main body case. The thing of FIG. 5 hooks the center part 5c of the code | cord | chord 5 on the hook 23 provided in the cylindrical trunk | drum outer surface 26 of the code | cord | chord storage member B, hold | maintains the code | cord | chord 5, and is wound and accommodated in this code | cord | chord storage member B (For example, refer to Patent Document 1). 6 shows that the end 5a of the cord 5 is passed through the through hole 25 of the cord holding portion 24 provided on the outer surface 26 of the cylindrical body portion of the cord storage member B until the cord central portion 5c reaches the cord holding portion 24. The cord 5 is folded and stored in the cord storage member B by bending the cord 5 at the cord central portion 5c (see, for example, Patent Document 2).
No. 2-5715 Japanese Utility Model Publication 1-35629

しかしながら、図4に示すコード保持機構では、コード5の端部5aに係止部材をカシメ等によって固定する必要がある。従って、刈刃用として特別に作成された高価な定尺ナイロンコードなどを用いる必要があり、加えて、弾性刈刃コードの交換が構造上から面倒になるなどの問題点があった。   However, in the cord holding mechanism shown in FIG. 4, it is necessary to fix the locking member to the end portion 5 a of the cord 5 by caulking or the like. Therefore, it is necessary to use an expensive standard nylon cord specially made for cutting blades, and in addition, there is a problem that replacement of the elastic cutting blade cord is troublesome from the structural viewpoint.

上記の問題を解決するために、図5や図6に記すコード保持機構が考案されているが、図5や図6に示すコード保持機構では、長いコードの中央部5bを探すのはとても煩雑かつ面倒である。また、図6においては長いコードの一端をコード収納部材Bの筒状胴部外面26に設けたコード保持部24の貫通孔25にコード中央部5cが該コード保持部24に至るまで通さなければならない為、コード収納部材Bへのコード巻回収納作業は一層の困難を増すという問題があった。   In order to solve the above problems, the cord holding mechanism shown in FIGS. 5 and 6 has been devised. However, in the cord holding mechanism shown in FIGS. 5 and 6, it is very complicated to find the central portion 5b of the long cord. And troublesome. In FIG. 6, one end of a long cord must pass through the through hole 25 of the cord holding portion 24 provided on the cylindrical body outer surface 26 of the cord storage member B until the cord central portion 5 c reaches the cord holding portion 24. Therefore, there is a problem that the cord winding and storing work on the cord storing member B is further difficult.

前記課題を解決するために、本考案では、刈払機の駆動軸に着脱自在に取り付けられ、本体部とカバー部よりなるコード保持装置において、前記本体部は、底部を有する筒状胴部と、前記筒状胴部の外周端部に設けられた前記カバー部を固定するカバー螺設部と、前記筒状胴部の外周部に設けられたコードを巻回収納する空隙を形成する大径フランジおよび小径フランジより構成されており、前記大径フランジと小径フランジ間には筒状胴部の内周部から外周部に貫通する2個のコード挿通孔が近接して設けられているコード型刈払機のコード保持装置としている。また、前記コード挿通孔は、外周側の口径が内周側の口径より大きく、且つ、本体回転方向の後部壁側がテーパー状に形成されている。   In order to solve the above problems, in the present invention, in a cord holding device that is detachably attached to a drive shaft of a brush cutter and includes a main body portion and a cover portion, the main body portion has a cylindrical body portion having a bottom portion, and A cover screwing portion for fixing the cover portion provided at an outer peripheral end portion of the cylindrical body portion, and a large-diameter flange forming a gap for winding and storing a cord provided at the outer periphery portion of the cylindrical body portion And a cord-type cutting device in which two cord insertion holes penetrating from the inner periphery to the outer periphery of the cylindrical body portion are provided between the large-diameter flange and the small-diameter flange. It is used as a cord holding device for a dispenser. The cord insertion hole has an outer diameter larger than an inner diameter, and a rear wall side in the main body rotation direction is tapered.

本考案によるコード保持装置では、本体部の大径フランジと小径フランジ間に筒状胴部の内周部から外周部に貫通する2個のコード挿通孔が近接して設けられている。これにより、筒状胴部の外周にコードを収納する際、特許文献1及び2に示すように、長いコードの中央部を探さなくてもよく、また貫通孔にコードの中央部まで通さなくてもよい。本考案では、コードの端部を一方の挿通孔の外側から内側に挿入後、他方の挿通孔の内側から外側に取り出して、筒状胴部の外周部に巻回することにより、確実に端部を固定できると共に、コードの巻回収納作業を容易に行うことができる。   In the cord holding device according to the present invention, two cord insertion holes penetrating from the inner peripheral portion of the cylindrical body portion to the outer peripheral portion are provided between the large-diameter flange and the small-diameter flange of the main body. As a result, when the cord is stored on the outer periphery of the cylindrical body portion, as shown in Patent Documents 1 and 2, it is not necessary to search for the central portion of the long cord, and it is not necessary to pass the central portion of the cord through the through hole. Also good. In the present invention, after inserting the end portion of the cord from the outside of one insertion hole to the inside, the cord is taken out from the inside of the other insertion hole and wound around the outer peripheral portion of the cylindrical body portion. The part can be fixed and the winding and storing operation of the cord can be easily performed.
