Abstract
【課題】草刈り作業に使用する刈刃において、水平な刈刃の一部分を上方向に湾曲させ、連続回転させた時に刃先が接地面に対し、上下に変動させることにより、ほぼ同時に近い力が繰り返される様に構成し、軽くスムーズな刈り取りが出来る動力付液状回転刈刃を提供する。【解決手段】円形水平な刈刃３に上から圧力を加え、中心から刃先に向かって緩やかな曲線のそり上がり４をつける。水平面に対するそり上がりは３〜７ミリ前後とする。これにより、連続回転させたときに刃先が波状の動きを繰り返し、軽くスムーズな刈り取りが出来るようになる。【選択図】図３In a cutting blade used for mowing work, when a part of a horizontal cutting blade is bent upward and is continuously rotated, the cutting edge is moved up and down with respect to the grounding surface, so that a force close to almost the same is repeated. Provided is a powered liquid rotary cutting blade that can be cut lightly and smoothly. Pressure is applied to a circular horizontal cutting blade 3 from above, and a gentle curve warpage 4 is applied from the center toward the cutting edge. The warpage relative to the horizontal plane is about 3 to 7 mm. As a result, the blade edge repeats a wave-like movement when continuously rotated, and light and smooth cutting can be performed.

Description
本考案は一般動力刃の安全性、作業効率性に関する。The present invention relates to the safety and work efficiency of a general power blade.
従来の動力刃は先端刃形状に色々違いがあるが、ストレート刈刃が主流である。Conventional power blades have various differences in tip blade shape, but a straight cutting blade is the mainstream.
（従来の刈刃について説明する）
従来の刈刃は、図１にその垂直断面を示すとおり、回転中心から先端までがほぼ真っ直ぐ水平なので刃先の食い込み、小石の跳ね返りが多く、危険性が高いものであった。(We explain the conventional cutting blade)
The conventional cutting blade, as its vertical cross section is shown in FIG. 1, is almost straight from the center of rotation to the tip, and therefore the cutting edge bites, pebble bounces, and the risk is high.
以上に述べた今までの動力刈刃は、刈り取り能力が遅く危険性が高いものであった。The above-mentioned power reaping blades have a slow cutting ability and a high risk.
本考案の刈刃は、図２に示す様に、従来の水平な刈刃の左右両端を上方向に少し曲げたもので、図３はそれを４５度回転させた場合に正面から見える図がである。
連続回転させた時にウェーブすることにより、持ち上げて刈る力と中間方向刃が、動力回転により、ほぼ同時に近い力が繰り返すことにより、軽くスムーズな刈り取りが出来る。The cutting blade according to the present invention, as shown in FIG. 2, is a slight bending of the left and right ends of the conventional horizontal cutting blade upward, and FIG. 3 shows a view seen from the front when it is rotated 45 degrees. It is.
By rotating at the time of continuous rotation, the force for lifting and cutting and the middle direction blade can repeat light close at the same time by power rotation, and light and smooth cutting can be performed.
接地面に対しては、刈刃を軽く置き左右に動かすだけで刈り取りが楽に出来る。With respect to the ground plane, cutting can be facilitated simply by placing the cutting blade lightly and moving it left and right.
又、接地面に対しては、同じ刃の位置で刈らないので、刈刃が数倍以上も長持ちする。In addition, since the ground surface is not cut at the same position of the blade, the cutting blade lasts several times or more.
又、ウェーブ刃の先端が図２，図３に示す様に、水平に対する上方向の曲げが３ミリ〜７ミリの範囲内であれば刈刃の能力はほとんど変わらない。Also, as shown in FIGS. 2 and 3, the tip of the wave blade hardly changes the cutting blade's ability if the upward bending with respect to the horizontal is in the range of 3 mm to 7 mm.
又、刈刃が上下変動することにより、隙間感覚があるので、刈刃の中央に巻き付きがほとんどない。In addition, since the cutting blade fluctuates up and down, there is a sense of clearance, so there is almost no winding at the center of the cutting blade.
次に刈刃がウェーブする事により、刃のぶれ、振動があると思われがちではあるが、円形中心軸回転なので、振動、ぶれは無いに等しい。Next, when the cutting blade is waved, it tends to be thought that there is a shake and vibration of the blade, but since it is a circular central axis rotation, the vibration and shake are equal.
以上に述べた様に、本考案のウェーブ刈刃は使用者に対して、安全性、刈り取りの軽さ、労力の短縮を追求した物を提供できる。As described above, the wave mowing blade of the present invention can provide the user with an object in which safety, lightness of cutting, and shortening of labor are sought.
本考案は一般的に流通している刈刃と比べ、安全性および作業効率の向上を達成可能とする。The present invention makes it possible to achieve an improvement in safety and work efficiency as compared with the commonly available cutting blades.
現在流通している刈刃の形状は、円形平面のものが主流である。The shape of the cutting blade currently in circulation is mainly circular.
従来の刈刃は、図１にその垂直断面を示すとおり、刃の中心から先端までが水平であり、刃先が地面や雑草に食い込んだり、小石に当たって跳ね返ったりして、危険性が高いものであった。また、そのような事象は作業効率の低下を来していた。The conventional cutting blade is horizontal from the center to the tip of the blade as shown in its vertical cross section in FIG. 1, and the cutting edge bites into the ground or weeds or bounces on pebbles, which is highly dangerous. The Also, such events have resulted in a reduction in work efficiency.
刃先の破損を避けるため、コンクリートや石の近くに生えた草は従来刈り残されがちであった。Traditionally, grass grown near concrete or stone has tended to be left behind to avoid breakage of the cutting edge.
本考案の刈刃は、図２に示す様に、水平な刈刃の一部分を上方向に湾曲させたものである。図３はそれを４５度回転させた場合に正面から見た図がである。
連続回転させた時に刃先が接地面に対し、上下に変動することにより、ほぼ同時に近い力が繰り返すことにより、軽くスムーズな刈り取りが出来る。The cutting blade according to the present invention is, as shown in FIG. 2, a portion of the horizontal cutting blade bent upward. FIG. 3 is a front view when it is rotated 45 degrees.
By rotating the blade edge up and down with respect to the ground contact surface when rotating continuously, a near-simultaneous force is repeated at the same time, making it possible to perform light and smooth cutting.
雑草を切断する刈刃の湾曲部下端は、小石等の障害物への接触が少ないため、切れ味が持続し、経済的効果が期待できる。Since the lower end of the curved portion of the cutting blade for cutting weeds has less contact with obstacles such as pebbles, sharpness can be sustained and economic effects can be expected.
本考案の刈刃は、図２、図３が示すように中心部から刃先の先端部に向かっての湾曲の度合いが３ミリから７ミリ前後あれば、一般的な刈刃と比べ、刈り取り能力の点ですぐれた成果があげられる。According to the cutting blade of the present invention, as shown in FIGS. 2 and 3, if the degree of curvature from the center to the tip of the cutting edge is about 3 mm to 7 mm, the cutting ability is better than that of a general cutting blade. Excellent results in terms of
本考案の刈刃は草刈り作業の際、刃先が上下変動するので、一般的な刈刃に比べ、中央部への雑草の巻き付きが少ない。Since the cutting edge of the cutting blade of the present invention fluctuates up and down during mowing work, weeds are less likely to be wound around the center compared to a general cutting blade.
刃先が石やコンクリートに当たって少々破損しても刈り取り能力はあまり変わらないので、縁石などの際に生えた草でも残すことなく刈り取れる。Even if the cutting edge hits a stone or concrete, even if it is slightly damaged, the cutting ability does not change much, so even grass grown during curbing can be cut without leaving it.
本考案の刈刃は刃面の形状が一般的なそれと異なるが、刃のぶれや異常な振動を起こすことはない。Although the cutting blade according to the present invention differs from the general shape of the blade surface, it does not cause any blurring of the blade or abnormal vibration.
以上に述べた様に、本考案のウェーブ刈刃は使用者に対して、安全性、刈り取りの軽さ、労力の短縮を追求した物を提供できる。As described above, the wave mowing blade of the present invention can provide the user with an object in which safety, lightness of cutting, and shortening of labor are sought.
本考案は一般的に流通している動力刈刃と比べ、安全性および作業効率の向上を達成可能とするものである。The present invention makes it possible to achieve an improvement in safety and work efficiency as compared with a generally available power repelling blade.
一般流通している刈刃の形状は、円形ストレートの物が主流である。The shape of the cutting blade in general circulation is mainly a circular straight one.
従来の刈刃は、刈刃中央から先端までがストレートであり、刈刃が接地面や雑草に食い込んだり、石などに当たると小石が跳ね返ったりし、又、縁石や石などにあたり刃先が損傷すると、円形バランスがくるいやすく、振動や刃先のブレが出やすく危険性があった。また、そのような支障は作業効率の低下を来していた。Conventional cutting blades are straight from the center to the tip of the cutting blade, and when the cutting blade bites into the contact surface or weeds, pebbles bounce off when it hits a stone etc. Also, if the cutting edge hits a curb or stone etc., There is a danger that the circular balance is easy to rotate, and vibration and blurring of the cutting edge are likely to occur. In addition, such troubles have resulted in a decrease in work efficiency.
又、刈刃、刃先の損傷を避けるためコンクリートの縁石や石の近くに生えた雑草は残されがちである為、前途の欠点を解決しようとしたものである。In addition, weeds tend to be left near concrete curbs and stones in order to avoid damage to cutting edges and cutting edges.
本考案刈刃は円形の左右部分を上方向に湾曲させたもので、円形をそり上げる事により、刈刃は緩やかに楕円回転し、それを動力回転で変動を繰り返すことにより回転中心への雑草の巻き付きや刃先の食い込みも少なく、スムーズな刈り取りを可能とした。The cutting blade according to the present invention is formed by curving the left and right portions of a circular shape upward, and by turning up the circular shape, the cutting blade is gently elliptically rotated, and the weed to the rotation center by repeating the fluctuation by power rotation. Less cutting and biting of the cutting edge, it was possible to cut smoothly.
又、接触部に対しては摩耗刃、逃げ刃、切り刃があり、逃げ、切り刃は上端部に近づくほど刃先の損傷が少なくなり、縁石、コンクリート、石などの障害物にあたってもウェーブ楕円回転を繰り返すため、長期しようが可能である。In addition, there is a wear blade, a relief blade, and a cutting blade for the contact part, and damage to the cutting edge decreases as the relief and the cutting blade approach the upper end, and the wave elliptical rotation also hits obstacles such as curb, concrete, and stone It is possible for a long time to repeat.
雑草に限らず、切断したものに対しては、刈刃上下部に絶えず隙間、間隔が保たれているので、刈刃回転部に対しては負荷が少なく、軽くて作業効率性にずぐれている。Not only for weeds, but for the cut ones, a gap and space are constantly maintained in the upper and lower part of the cutting blade, so the load on the rotating part of the cutting blade is small and light, which makes it easy to work efficiently There is.
又、刈刃、刃先全体が摩耗しても、刈刃先端部に凹凸が少しでもあれば、ウェーブ楕円回転が動力で瞬時に加わる為、新しい刈刃に匹敵する刈り取りが長期にわたり可能である。In addition, even if the cutting blade and the whole cutting edge wear, even if there is a slight unevenness at the cutting blade tip, the wave elliptical rotation is instantaneously added by the power, so that cutting equivalent to a new cutting blade is possible for a long time.
本考案の刈刃は、形状は一般的刈刃とは異なるが、緩やかな楕円ウェーブ形状である為、バランス感覚に優れ、刈刃が損傷しても異常な振動やブレを起こすことは少ない。The cutting blade according to the present invention is different in shape from a general cutting blade, but since it has a gentle elliptical wave shape, it is excellent in sense of balance, and even if the cutting blade is damaged, it does not cause abnormal vibration or blurring.
以上に述べた本考案は、使用者に対して安全性、刈り取りの軽さ、労力の軽減と刈刃の長期使用を可能としたものであり、それを動力で回転させることを特徴とする動力ウェーブ刈刃。The present invention described above is intended to provide the user with safety, lightness of cutting, reduction of labor and long-term use of the cutting blade, and is characterized by power-driven rotation of the cutting blade.
