Description
【考案の詳細な説明】 本考案は草刈り用回転刃の改良に関するものである。[Detailed explanation of the idea] The present invention relates to an improvement of a rotary blade for mowing grass.
従来の草刈り用回転刃は、円板の外周に鋸刃状の切断刃
を形設したものが通常用いられて（・たがこれらのもの
は刃の部分に石が当接して欠げたり、あるｔ・は刃が磨
耗するとたちまち切味が低下し、使用不可能となるので
、刃の寿命力筒いという欠点を有してし・た。Conventional rotary blades for mowing have a disc with a saw-like cutting blade formed on the outer periphery (・However, these blades are prone to chipping due to stones coming into contact with the blade, Some types of blades have the disadvantage that when the blade wears out, the sharpness immediately deteriorates and the blade becomes unusable, resulting in a short blade life.
本考案はこれらの点を改良して、長期の使用に耐える草
刈り用回転刃を具現するものである。The present invention improves these points to realize a rotary mowing blade that can withstand long-term use.
以下これを実施例図について説明する。This will be explained below with reference to embodiment figures.
中心部に回転軸（図示せず）への取付穴１を設けた回転
刃Ａａ’平板放射状に形威し、この回転刃Ａの回転方向
（矢印方向）に対し、前方側にお（・て、前記回転刃Ａ
の基部よりに刀刃状の切刃部２を設け、そしてこの切刃
部２の先方に順次鋸刃状の切断刃３を刻設し、更に切断
刃３の最先端部を基部として後方に傾斜すると共に先部
が回転軸を中心にして前記切断刃３の最先端部を通る円
周より外方に突出して（・る石等の物体を跳飛ばし用の
防護先端部４を設けて全体を構成する。The rotary blade Aa' has a radial shape as a flat plate with a mounting hole 1 for a rotating shaft (not shown) in the center, and a rotary blade ( , the rotary blade A
A sword-like cutting edge 2 is provided at the base of the blade, and saw-blade-shaped cutting blades 3 are successively carved at the tip of this cutting edge 2, and the tip of the cutting blade 3 is tilted rearward with the tip of the cutting edge 3 as the base. At the same time, the tip protrudes outward from the circumference passing through the cutting edge of the cutting blade 3 with the rotation axis as the center. Configure.
次に作用効果を説明する。Next, the effects will be explained.
回転刃Ａが矢印方向に回転すると、草が切刃部２もしく
は切断刃３に当接して切断される。When the rotary blade A rotates in the direction of the arrow, the grass comes into contact with the cutting blade portion 2 or the cutting blade 3 and is cut.
そして本体最先端には防護先端部４が設けられているの
で作業生石等の物体に接触しても先づこれを跳ねとばす
こととなる。Since a protective tip 4 is provided at the most extreme end of the main body, even if it comes into contact with an object such as raw stone, it will be thrown away first.
従って鋸状切断刃３及び切刃部２を保護する状態となり
、若し石等が切断刃３、切刃部２に接触してもこれ等刃
部の損傷は極めて僅少となり、切断刃３及び切刃部２が
順次草刈り作用するので切味は低下せず、長期の使用に
も十分耐える効果を有し、更に本考案は刀刃状の切刃部
２と、鋸刃状の切断刃３の２段構えであるから切味もよ
く、刈り残し等の心配がない等、実用性大なる効果を奏
するものである。Therefore, the serrated cutting blade 3 and the cutting blade part 2 are protected, and even if a stone etc. comes into contact with the cutting blade 3 and the cutting blade part 2, the damage to these blade parts is extremely small, and the cutting blade 3 and the cutting blade part 2 are protected. Since the cutting blade part 2 acts to cut the grass in sequence, the cutting quality does not deteriorate and it has the effect of being able to withstand long-term use. Since it has a two-stage structure, it cuts well and there is no need to worry about leaving uncut parts, so it has great practical effects.
図は本案実施の態様を例示する平面図である。
Ａは回転刃、２は切刃部、３は切断刃、４は石等の物体
を跳飛ばし用の先端部である。The figure is a plan view illustrating an embodiment of the present invention. A is a rotating blade, 2 is a cutting blade part, 3 is a cutting blade, and 4 is a tip part for flying away objects such as stones.
