Abstract
Description
本発明は、草や小木を刈り取る作業において刈り取られ物が作業をする者に向かわせずに向こう側に飛ばすことができ、さらに石などの固い物や木の幹に当るも食い込まさせずに逃げることができる特に、草刈り機用の刈り取り刃に関するものである。 In the present invention, in the work of cutting grass and trees, the material can be repelled to the other side without being directed to the person doing the work, and it can also escape without hitting the hard object such as stone or the trunk of the tree. In particular, it relates to a mowing blade for a mower.
従来、円形の形状に合わせて刈り取り刃が回転をする方向に爪状の刃が多数に設けられたもの、円形をさせた外側に垂直に短くの刈り取り刃を数カ所に設けてあるものなどがある。また、長方形の形状をする刈り取り刃等が市販をされ人々に知られている。 In the prior art, there are a number of claw-shaped blades provided in the direction in which the cutting blade rotates in accordance with the circular shape, and a circular cutting edge provided with several short cutting blades vertically vertically. . In addition, a cutting blade or the like having a rectangular shape is commercially available and known to people.
従来の刈り取り刃は、次のような欠点があった。
（イ）、爪状の刃が盤の回転方向に向け小刻みに設けてあるものを使用をするが刈り取られた物が作業をする者に向かってくる怖さがあった。。
（ロ）、円形状の外側部に垂直にある刃や長方形の形状をする刃にも、刈り取られた物が作業をする者に向かってくる怖さと、太い草茎や雑木に当たるときの反動が強く身体や草刈り機本体を傷めることがあった。
（ハ）、盤は左回転でするので、回転側に向かう刃がきつい角度、或は長方形に設けられていることは（イ）、（ロ）、において、刃が刈り取られた物を作業をする側に寄せることになり、盤の回転を強くする毎に手前に飛ぶことがより多くなるのである。
本発明は、以上の問題点を解決するために発明されたものである。Conventional cutting blades have the following disadvantages.
(A) There is a fear that the clipped material will come to the person doing the work, though the claw-like blade is used in the direction of rotation of the disc in small increments. .
(B) The blade in the vertical direction on the outer side of the circular shape and the blade in the shape of a rectangle also have the fear that the clipped material will come to the person doing the work and the reaction when it hits thick grass stems and mixed trees There was a strong injury to the body and the body of the mower.
(C) Since the board rotates in the left direction, it is necessary that the blade facing the rotation side is provided at a tight angle or in a rectangular shape. The more you turn to the front, the more you turn up the board.
The present invention has been invented to solve the above problems.
盤（１）の外周を円形状に合わせ外側部を反り刃（２）とし、反り刃（２）の回転をする方向に反り曲線（３）を設け先端部（５）と背側部（４）を設ける。
さらに、反り刃（２）の空間部（８）下部に幅をする円部（６）を設け、反り曲線（３）と先端部（５）と円部（６）に刃（７）を設ける。
以上の構成よりなる草刈り機用刈り取り刃。Set the outer periphery of the disc (1) to a circular shape and set the outer part as a cambered blade (2), provide a cambered curve (3) in the direction to rotate the cambered blade (2), and make the tip (5) )).
Furthermore, a circular portion (6) having a width is provided in the lower portion of the space portion (8) of the warping blade (2), and a blade (7) is provided in the warping curve (3), the tip portion (5) and the circular portion (6) .
A mower cutting blade comprising the above structure.
本発明を使用することによって、反り刃であることから刈り取られた物を作業をする者の向こう側に飛ばし向かってくることを防ぎ、木々への食い込みをしながらも逃げ去るようになり身体に及ぼす衝撃の危険と機体の損傷を防ぐことができる。
また本発明は、反り刃との間に空間部があることから盤に軽さがあり、長尺丈の刈り取る物も上面から中頃から下面からと思う所の位置で機体の重さを気にする事無く作業が可能であり、合わせて、反り刃との間に刈り取られる物が入り易く、この長尺丈の上面から下面にと反り刃を回転をさせながら降下をさせると上面から刻みの刈り取りをさせるので、長尺丈で繁る篠竹作業の用途にも及ぶことができる。By using the present invention, since it is a cambered blade, it is prevented from flying toward the other side of the working person from the material being cut off, and it escapes while biting into trees, and it becomes a body. It can prevent the risk of impact and damage to the aircraft.
In the present invention, there is a space between the warp blade and the board, and the board is light, so long cut objects are also concerned about the weight of the machine from the top to the middle from the bottom. Work is possible without doing it, and it is easy to put in the thing to be clipped between warpage blade together, and if it is made to descend while rotating the warpage blade from the upper surface to the lower surface of this long length, it will be cut from the upper surface Since it is reaped, it can be extended to the use of long bamboo shoots.
以下、本発明の実施の形態を説明する。
（イ）、盤（１）の外側部を反り刃（２）とし、反り刃（２）の回転をする方向に反り曲線（３）を設け、先端部（５）と背側部（４）を設ける。さらに、反り刃（２）の空間部（８）下部に幅をする円部（６）を設け、反り曲線（３）と先端部（５）と円部（６）とに刃（７）を設ける。
（ロ）、反り曲線（３）の曲線角度は適宜な曲線を保持し、先端部（５）を適宜な幅とほぼ平行と、背側部（４）の傾斜を適宜な角度とさせ円部（６）の幅の長短を適宜に計り、円状を適宜な角度に保持をする。
（ハ）、盤（１）とし、鉄材鋼材、合金系材質で用途により反り曲線（３）と先端部（５）と円部（６）とに片刃、両刃、凹み刃、超合金刃、ダイヤモンド刃を設けるを要するとし、盤（１）の回転作用による風圧を逃がす穴を設けるを要するとする。
本発明は以上の構成よりなる。
本発明を使用する場合は、盤（１）とし、盤（１）が回転をする方向に反り刃（２）の反り曲線（３）を合わせて草刈り機取付部（９）を草刈り機本体に装着をして使用することができる。Hereinafter, embodiments of the present invention will be described.
(I) The outer part of the board (1) is a warping blade (2), and a warping curve (3) is provided in the direction in which the warping blade (2) rotates, and the tip (5) and the back side (4) Provide Further, a circular portion (6) having a width in the lower portion of the space portion (8) of the warping blade (2) is provided, and the blade (7) is formed on the warping curve (3), the tip portion (5) and the circular portion (6) Set up.
(B) The curve angle of the warpage curve (3) holds an appropriate curve, and the tip end (5) is approximately parallel to the appropriate width, and the inclination of the back side (4) is an appropriate angle to make the circle part Measure the length of the width of (6) as appropriate, and hold the circular shape at an appropriate angle.
(C), the board (1), iron material steel material, alloy material, depending on the application Warping curve (3), tip (5) and circular part (6), single-edged, double-edged, concaved, super alloyed, diamond It is necessary to provide a blade, and it is necessary to provide a hole for releasing the wind pressure due to the rotating action of the disc (1).
The present invention is configured as described above.
When using the present invention, make the board (1), fit the warp curve (3) of the warping blade (2) in the direction in which the board (1) rotates and fit the mower mounting part (9) to the mower body Can be used.
