(57) [Summary] (Correction) [Purpose] Prevents scattering of stones and wooden turnips when mowing. [Structure] A main body frame 1 which is adapted to be attached to and detached from a drive shaft of a main body of a mower, and flexible blades 10 and 11 are detachably connected to the main body frame 1. [Effect] The flexible blade is safe because it does not fly off the stone or wooden turnip even if it hits the stone or wooden turnip.
Description
【考案の詳細な説明】 この考案は、手押し式または自走式などの中型から大型の草刈り機用に適した フレキシブルタイプの回転刃に関するものである。[Detailed Description of the Invention] The present invention relates to a rotary blade of a flexible type suitable for a medium-sized to large-sized mower such as a hand-operated type or a self-propelled type.
従来、手押し式や自走式の中型から大型の草刈り機では、第４図のような板刃 を使っているが石や木かぶを弾いた時石や木かぶが飛び散ったり、刃止めボルト が切れて刃そのものが飛び散ったりして大変危険であった。ショルダータイプの ハンディ草刈り機では、円盤刃に代えてナイロン紐の刃も利用されてきているが 、強度がなくて、本考案の目的である中型、大型の草刈り機には適さない。 Conventionally, in hand-held or self-propelled medium to large sized mowers, a plate blade as shown in Fig. 4 is used, but when a stone or wooden turnip is hit, the stone or wooden turnip scatters or the blade stop bolt is cut off. The blade itself was scattered and it was very dangerous. In shoulder type handy mowers, nylon string blades have been used instead of disc blades, but they are not strong enough and are not suitable for the medium- and large-sized mowers that are the object of the present invention.
この考案は、上記のような問題を解決するためになされたもので、回転刃に鎖 やチエーンあるいはワイヤー類を使ったものに関する。 The present invention was made to solve the above problems, and relates to a rotary blade that uses chains, chains, or wires.
つぎに、この考案の一実施例を添付図面について説明する。 Next, an embodiment of the present invention will be described with reference to the accompanying drawings.
第１図〜第３図に示すものは、鎖を用いたこの考案の一実施例を示すもので、 （１）は円盤状の本体枠で、この本体枠（１）には草刈り機本体のドライブシャ フト（２）にボルト（３）で固定するための４ケ所の孔（４）を設け、周部は立 ち上がり縁（５）を形成し、この縁（５）には対称の４ケ所に切り溝（６）を設 け、また縁（５）の内側数か所には取付けステー（７）を凸設し、このステー（ ７）に蓋盤（８）をボルト（９）で固定するようにしてある。 1 to 3 show an embodiment of the present invention using a chain. (1) is a disk-shaped main body frame, and the main body frame (1) has a drive of the main body of the mower. The shaft (2) is provided with four holes (4) for fixing with bolts (3), the peripheral part has rising edges (5), and these edges (5) have four symmetrical points. A kerf (6) is provided on the ridge (5), and mounting stays (7) are provided at several places inside the edge (5), and the lid (8) is fixed to the stay (7) with bolts (9). I am doing it.
そして、この本体枠（１）の縁（５）に設けた切り溝（６）に鎖（１０）の内 端部を第３図に示すようにはめ込み、蓋盤（８）をボルト（９）で固定する。 Then, the inner end of the chain (10) is fitted into the kerf (6) provided on the edge (5) of the main body frame (1) as shown in FIG. 3, and the cover plate (8) is fixed with the bolt (9). Fix with.
なお、鎖（１０）は外部に２０ｃｍ〜３０ｃｍを出し、余りは本体枠（１）内 に収納する。第５図に示したものは、鎖（１０）の代りにワイヤーを使った他の 一実施例を示すもので、この実施例では、直径３ｍｍ〜５ｍｍの鋼製撚りワイヤ ー（１１）に３ｃｍ〜５ｃｍ間隔でストッパー（１２）を複数個固定して成り、 このストッパー（１２）はワイヤー（１１）に金属パイプを通して所定の位置で かしめて固定する。 The chain (10) projects 20 cm to 30 cm outside, and the remainder is stored in the main frame (1). FIG. 5 shows another embodiment in which a wire is used instead of the chain (10). In this embodiment, a steel twisted wire (11) having a diameter of 3 mm to 5 mm has a diameter of 3 cm. A plurality of stoppers (12) are fixed at intervals of ~ 5 cm, and the stoppers (12) are fixed by crimping a wire (11) through a metal pipe at a predetermined position.
この考案は上述のように構成したので、草刈り機のドライブシャフト（２）に 取付けて従来のように回転させることにより、鎖（１０）やワイヤー（１１）が 草を刈り取っていくものである。 Since the present invention is constructed as described above, the chain (10) and the wire (11) cut the grass by attaching it to the drive shaft (2) of the mower and rotating it in the conventional manner.
そして、作業中に鎖（１０）やワイヤー（１１）が石や木かぶに当たっても鎖 （１０）やワイヤー（１１）の方がはじかれて石や木かぶが飛び散ることがなく 、極めて安全に草刈り作業ができるものである。 And even if the chain (10) or wire (11) hits a stone or a tree turnip during work, the chain (10) or the wire (11) will not be repelled and the stone or tree turnip will not scatter, and it is very safe to mow. You can work.
なお、鎖（１０）やワイヤー（１１）の余り部分を本体枠（１）内に収納でき るので、鎖（１０）やワイヤー（１１）の先端部がすり減ったり、傷んだりした 場合は、順次繰り出して使うことができ、鎖（１０）やワイヤー（１１）の取り 替え頻度を下げることができ、無駄なく使用できるものである。 In addition, since the remainder of the chain (10) and the wire (11) can be stored in the main body frame (1), if the tips of the chain (10) and the wire (11) are worn or damaged, the It can be extended and used, the frequency of replacement of chains (10) and wires (11) can be reduced, and it can be used without waste.
