【考案の詳細な説明】
この考案は、主として牧草や雑草類などの刈取
作業に用いられるロータリモアにおける、刈刃に
関する。[Detailed Description of the Invention] This invention relates to a cutting blade in a rotary mower used mainly for cutting grass, weeds, etc.
従来のロータリモアは、材料色（黒色）のまま
刈刃をロータリデイスクに取付けて構成している
ので、刈取作業中の刈刃の回転進行位置を的確に
とらえにくく、ために刈ぎわを不整にしてしまつ
たり、刈刃を障害物に接当させてしまつて危険を
まねくといつた不具合があり、又、機械停止中に
おいても、刈刃の存在位置が土壌等周囲のものか
ら判別しにくくて、やゝもすると刈刃に接当して
しまい易く、人身事故を引き起してしまうといつ
た不具合もあつた。 Conventional rotary mowers are constructed by attaching the cutting blade to a rotary disk while maintaining the color of the material (black), which makes it difficult to accurately determine the rotational position of the cutting blade during reaping work, resulting in uneven cutting lines. There are some problems where the cutting blade may fall off or come into contact with an obstacle, causing danger.Also, even when the machine is stopped, it is difficult to determine the position of the cutting blade from surrounding objects such as the soil. However, there was also a problem where the blade could easily come into contact with the cutting blade, causing an accident resulting in injury or death.
そこで、本考案は比較的簡単な構成で、上記の
不具合点を解消することができるロータリモア用
刈刃を提供することを目的として実施したもので
ある。 Therefore, the present invention has been implemented for the purpose of providing a cutting blade for a rotary mower that has a relatively simple configuration and can eliminate the above-mentioned problems.
以下、本考案の一実施例を、添付図面にしたが
つて説明する。 An embodiment of the present invention will be described below with reference to the accompanying drawings.
第１図はロータリモアの全体平面図であり、図
中の符号Ｒは機体、１は駆動車輪、２はエンジ
ン、３は操縦ハンドルを示す。 FIG. 1 is an overall plan view of a rotary mower, in which reference numeral R indicates a body, 1 a drive wheel, 2 an engine, and 3 a control handle.
図にはあらわれていないが、機体Ｒの前部に
は、前記エンジンに連動連結された刈取駆動ケー
スが設けられ、その駆動ケースから下方にむけて
刈取駆動軸を突設している。 Although not shown in the figure, a reaping drive case is provided at the front of the machine body R and is interlocked with the engine, and a reaping drive shaft projects downward from the drive case.
刈取駆動軸には、上面に跳ね出し翼４，４をも
つたロータリデイスクＡが、軸と一体に回転する
ように取付けられる。 A rotary disk A having spring blades 4, 4 on its upper surface is attached to the reaping drive shaft so as to rotate together with the shaft.
ロータリデイスクＡ（以下の説明ではデイスク
Ａと呼ぶ）の回転外径ａの近傍部には複数個の刈
刃取付部５が設けられ、夫々の取付部は、デイス
クＡに穿設される締結具挿通孔と、該孔に貫挿さ
れて緩み止めが施される締結具６とから形成され
る。 A plurality of cutting blade attachment portions 5 are provided in the vicinity of the rotational outer diameter a of the rotary disk A (referred to as disk A in the following description), and each attachment portion is connected to a fastener drilled in the disk A. It is formed from an insertion hole and a fastener 6 that is inserted through the hole to prevent loosening.
７はロータリモア用の刈刃で、前記構成の刈刃
取付部５，５に着脱自在に取付け固定され、刃部
７ａ，７ａが刈取作用可能なように、前記デイス
クＡの回転外径ａから、さらに外方に突出するよ
うになされる。 Reference numeral 7 denotes a cutting blade for a rotary mower, which is removably attached and fixed to the cutting blade attachment parts 5, 5 having the above-mentioned structure. , further protruding outward.
刃部７ａ，７ａは、刈刃７のデイスクＡの回転
外径ａからの突出部において、表裏両面に形成さ
れるのであり、表裏を反転して刈刃取付部５に装
すことによつて２回の使用が可能なようになつて
いる。 The blade portions 7a, 7a are formed on both the front and back surfaces at the protruding portion of the cutting blade 7 from the rotational outer diameter a of the disc A. It is designed to be used twice.
そして、刈刃７のデイスクＡの回転外径ａから
の突出部には、第４図に断面状態が図示されるよ
うな凹陥部Ｂが設けられ、その凹陥部Ｂを、塗装
やテープの貼着あるいは、その他の適宜の手段で
彩色するのである。 A concave part B, the cross-sectional state of which is shown in FIG. They can be colored by dyeing or by other appropriate means.
凹陥部Ｂに施す色彩は、黄色、赤色といつたよ
うな目立ちのよい色になす。 The color applied to the concave portion B is a conspicuous color such as yellow or red.
本考案のロータリモア用刈刃は、以上のような
構成になるので、回転中の刈刃位置が、彩色によ
つて的確に把握できることになり、刈ぎわを整斉
にする刈取作業が行え、刈刃を障害物に接当させ
て危険をまねくといつた事態を回避した安全作業
が実施できる。 The cutting blade for a rotary mower of the present invention has the above-described configuration, so the position of the cutting blade during rotation can be accurately grasped by coloring, and the cutting work can be performed to align the cutting line. It is possible to carry out safe work that avoids situations where the cutting blade comes into contact with an obstacle and causes danger.
また、刈刃は彩色によつて周囲の土壌等から目
だつようになるので、停止中の刈刃の位置確認が
できないで、つい触れてしまうようなことも防止
でき、全体として機械を安全に用い得るのであ
る。 In addition, the coloring of the cutting blade makes it more visible from the surrounding soil, which prevents the user from accidentally touching the cutting blade without being able to check its position while the machine is stopped. You get it.
しかも、彩色するに際しては、刈刃の必要部分
に凹陥部Ｂを設けて該部に色彩を施すので、刈刃
が作動しても彩色は比較的損耗しにくく長期の使
用に耐え得るのである。 Moreover, when coloring, the recessed portion B is provided in the necessary part of the cutting blade and the coloring is applied to that part, so that even when the cutting blade is operated, the coloring is relatively less likely to wear out and can withstand long-term use.
