本考案は、耕耘機の動力伝動ケースから突出した耕耘軸に耕耘刃を複数備えた 耕耘作業体の上方位置を被覆し、特にエンジン及びその周辺の装置に土がかから ないようにするのみならず、耕耘作業体に小石等が挟みこまれないようにし、且 つ堅牢にできる耕耘機の耕耘カバーに関する。 The present invention covers the upper position of a tilling work body having a plurality of tilling blades on a tilling shaft protruding from a power transmission case of a tiller, and only when it is necessary to prevent the engine and surrounding devices from being soiled. In addition, the present invention relates to a tilling cover for a tiller that prevents pebbles and the like from being caught in a tilling work body and is robust.

従来より、耕耘機（ロータリー式も含む）の動力伝動ケースの左右両側より突 出する耕耘軸には、六角形状筒体の耕耘筒に複数の耕耘機刃を備えた耕耘作業体 を装着している。その耕耘作業体の上方位置には耕耘作業時に跳ね上がる土がエ ンジン及びその周辺部分に被らないようにするために土よけを目的としたカバー が装着されている。その耕耘軸にタイヤを装着すると車輪カバーとなるものであ る。 Conventionally, the cultivating shaft protruding from the left and right sides of the power transmission case of the cultivator (including the rotary type) has been equipped with a cultivating work body equipped with multiple cultivator blades in a hexagonal cultivating cylinder. There is. At the upper position of the tilling work body, a cover is installed for the purpose of preventing soil from splashing up during the tilling work so as not to cover the engine and the surrounding area. When a tire is attached to the cultivated shaft, it becomes a wheel cover.
【０００３】 そのカバーは、一般的には耕耘作業体の耕耘刃の回転半径よりも大きな曲率半 径を有し、その耕耘刃の最外周の描く回転円周よりも外側位置となるように配置 されたものである。このように、耕耘カバーは回転する耕耘刃による土の跳ね上 がりや、土壌中に含まれている石の塊が耕耘機本体に飛び跳ねて当たってくるの を防止し、損傷を受けにくいようにするものである。The cover generally has a radius of curvature larger than the radius of rotation of the plowing blade of the plowing work body, and is arranged so as to be located outside the rotational circumference drawn by the outermost periphery of the plowing blade. It was done. In this way, the cultivating cover prevents the soil from jumping up by the rotating plowing blades and the stone blocks contained in the soil from jumping and hitting the cultivator body, making it less susceptible to damage. To do.
【０００４】[0004]
上述したように耕耘軸に耕耘作業体のカバーは、耕耘機本体を回転する耕耘刃 により跳ね上がる土や、石等から防御するため、或いは作業員が高速回転する耕 耘作業体から身を守るためにも装着される。そのカバーは、一般のものでは円弧 状に形成されることが多く、また耕耘作業体の耕耘刃の回転半径よりも大きくし てある。そのために、高速回転する耕耘刃によって土中に混じって石が耕耘刃に より押し跳ね上げられてカバーと耕耘刃との間に入ってくることがある。 As described above, the cover of the tilling work body on the tilling shaft is used to protect the body of the tiller from the soil and stones that jump up by the rotating tiller blade, or to protect the worker from the rotating tiller work body at high speed. Will also be installed. The cover is usually formed in an arc shape in general, and is larger than the turning radius of the plowing blade of the plowing work body. For this reason, the high-speed rotating plowing blade may mix into the soil and push stones up by the plowing blade to enter between the cover and the plowing blade.
【０００５】 このときに、回転ず耕耘刃とともに石がカバーの裏面側をこすり、カバーを傷 める結果を引き起こす。さらに、入り込んだ小石は高速回転する耕耘機により、 カバー内を高速回転する耕耘刃により、カバーを耕耘機本体に装着しているボル ト・ナット等に当たり、ボルトを切断し、カバーの装着具合を不良とし、最悪の 場合にはカバーが本体から脱落してしまうことがある。At this time, the stone rubs against the back side of the cover without rotating and causes damage to the cover. In addition, the pebble that entered is hit by the cultivator that rotates at high speed, and the cultivating blade that rotates at high speed inside the cover hits the cover with bolts and nuts that are attached to the body of the cultivator. If it is defective, the cover may fall off from the main body in the worst case.

そこで、考案者は上記課題を解決すべく鋭意，研究を重ねた結果、本考案を、 複数の平坦面板部を折線状部を介して多角形円弧状に連続成形し、耕耘作業体の 耕耘刃の回転軌跡円の外側に沿って位置するようにしてなる耕耘カバーとしたこ とにより、エンジン等を好適に覆い、石等を良好に脱落させ、極めて強固且つ耐 久性のあるものとし、上記課題を解決したものである。 Therefore, as a result of the inventors' earnest studies and researches to solve the above-mentioned problems, as a result of the present invention, a plurality of flat face plate portions are continuously formed into polygonal arc shapes through fold line portions to form a plowing blade for a tilling work body. The plowing cover is located along the outside of the rotation locus circle, so that the engine etc. can be covered properly and stones, etc. can be removed well, and it is extremely strong and durable. It is a solution to the problem.
