Description
本発明は草刈機用カバーに関し、特にナイロンコードを高速回転させることによって草刈り作業を行う草刈機に好適なカバーに関する。 The present invention relates to a cover for a mower, and particularly to a cover suitable for a mower that performs mowing work by rotating a nylon cord at high speed.
草刈機における刈刃としては、金属刃、ナイロンカッター、樹脂刃等があり、草刈り作業が行われる場所の環境や作業範囲、作業箇所等に応じて選択される。特に、ナイロンカッターは、障害物に沿って草刈り作業を行う場合（所謂、キワ刈り）や砂利が多い場所等に適しており、最近ではケーブル等が張り巡らされ、金属刃の使用が危険な太陽光発電設備における維持管理作業において、太陽光パネルの設置土台周辺等の草刈り作業に利用されている。 The cutting blade of a lawn mower includes a metal blade, a nylon cutter, a resin blade, etc., and is selected depending on the environment, work range, work location, etc. of the place where the grass cutting work is performed. In particular, nylon cutters are suitable for mowing along obstacles (so-called edge cutting) and in areas with a lot of gravel. In the maintenance work of photovoltaic power generation equipment, it is used to cut grass around the installation base of solar panels.
しかし、ナイロンカーターによる草刈り作業においては、ナイロンカッターが多くの砂利や刈り取った雑草等を周囲に飛散させ、砂埃等も発生しやすい。従って、太陽光発電設備においては、ナイロンカッターによって飛散した砂利が太陽光パネルを損傷するおそれや、砂埃によって太陽光パネル表面が汚れてしまうといった問題がある。 However, in mowing work using a nylon cutter, the nylon cutter scatters a lot of gravel, cut weeds, and the like into the surrounding area, and dust is also likely to be generated. Therefore, in solar power generation equipment, there is a problem that the gravel scattered by the nylon cutter may damage the solar panel, and the surface of the solar panel may become dirty due to dust.
また、従来から草刈機用のカバーに関する種々の発明が開示されている（例えば特許文献１及び特許文献２参照。）。特許文献１に開示された草刈機防塵カバーは、草刈機、回転ローター切刃、ナイロンカッター上部と側面部に透明合成樹脂（ビニール）カバーを設けたことを特徴とし、側面部は地面に接触する構成とされている。 Furthermore, various inventions relating to covers for mowers have been disclosed (for example, see Patent Document 1 and Patent Document 2). The mower dustproof cover disclosed in Patent Document 1 is characterized in that a transparent synthetic resin (vinyl) cover is provided on the upper and side parts of the mower, the rotating rotor cutting blade, and the nylon cutter, and the side parts are in contact with the ground. It is said to be composed of
上記の構成を備える特許文献１に係る草刈機防塵カバーによると、「小石、小枝、雑草等の跳ね乗離もなく、土ぼこり、砂ぼこりも飛ばさず、環境にもよく、防塵カバーの素材が合成樹脂（ビニール）で物体が追突しても衝撃が激減、草刈機使用にも安定性が確保できる。カバーが透明で回転ローター部の切刃、ナイロンカッター部を観察しながら作業できる。」と記載されている。 According to the lawn mower dust-proof cover according to Patent Document 1 having the above-mentioned configuration, ``no stones, twigs, weeds, etc. bounce off, and no dust or sand is thrown away, which is good for the environment, and the material of the dust-proof cover is made of synthetic resin. (Vinyl) dramatically reduces the impact even if an object collides with it, ensuring stability when using a mower.The cover is transparent, allowing you to work while observing the cutting blade of the rotating rotor and the nylon cutter.'' ing.
また、特許文献２に開示された飛散物防護プラスチックカバーは、「草刈り機で草刈り、草取りに飛散物が顔面や人体、作物等に当り損傷被害を被っていた、草刈り機のネック部分にプラスチックカバーをかぶせ、ナイロン紐カッター使用時は、平版で広く取り、飛散物を受け止め、板の手前部分を下方に折り曲げることにより、足元の飛散物防護カバーとする、地上地中の草取りカッター使用には上、側壁の飛散物を受け止め、防護できる物として、ポット型プラスチック防護カバーとして、両具共に手前部分に軌道軸パイプを入れる穴を設ける、挿入切り込み口から押しこみ、穴に治める、こうすることにより安定した装備により飛散物防護ができる」ことを特徴としている。 In addition, the plastic cover for protecting against flying objects disclosed in Patent Document 2 is a plastic cover that covers the neck of a lawn mower, where flying objects hit the face, human body, crops, etc. when mowing with a lawn mower, causing damage. When using a nylon cord cutter, use a flat plate to catch the flying debris, and by bending the front part of the board downwards, it becomes a protective cover for your feet from flying debris.When using the weed cutter above ground, use the top and side walls. As a pot-shaped plastic protective cover that can catch and protect against flying objects, both tools have a hole in the front part to insert the orbital shaft pipe, push it through the insertion notch, and fix it in the hole.This makes it stable. It is characterized by the ability to protect against flying objects by equipping it with equipment.
上記の構成を備える特許文献２に係る飛散物防護プラスチックカバーによると、「飛散物防護、にプラスチックカバーを草刈り機のネック部分に取付けるだけで防護完備出来るのである、ナイロン紐カッターではプラスチックカバーを被せたままで刈り取りたい部分の確認がとれて、その作業を進ませることができる、草取りカッターでの使用はポット型飛散物防護カバーを被せ、作物の間の草とりをして、隣接作物をいためない人体にも飛散しない」と記載されている。 According to the flying object protection plastic cover according to Patent Document 2 having the above configuration, ``For flying object protection, it is possible to provide complete protection by simply attaching the plastic cover to the neck part of the mower. You can confirm the area you want to cut and proceed with the work. When using a weeding cutter, cover it with a pot-shaped flying object protection cover and weed between crops to prevent damage to adjacent crops. "Does not scatter."
上記のとおり、障害物が多い場所の草刈り作業においてはナイロンカッターが好適である。しかし、金属刃や樹脂刃に比べて飛散物が多いため、飛散物によって草刈り作業を行う場所に設置されている周辺設備を損傷するおそれがあり、非常に慎重な作業が要求されるため、作業効率が非常に悪かった。 As mentioned above, a nylon cutter is suitable for mowing work in areas where there are many obstacles. However, since there are more flying objects than metal blades or resin blades, there is a risk that the flying objects may damage surrounding equipment installed in the area where mowing work is performed, and very careful work is required. It was very inefficient.
また、特許文献１に開示された草刈機防塵カバーや特許文献２に開示された飛散物防護プラスチックカバーによると、刈り取った雑草や砂利の飛散をある程度、防ぐことができるものと思料する。しかし、特許文献１に開示された草刈機防塵カバーでは、前方に進みながら草刈り作業を行ったり、作業者を中心に左右に円弧を描きながら草刈り作業を行ったりする場合、防塵カバーが地面に引っ掛かるおそれがある。 Furthermore, according to the mower dustproof cover disclosed in Patent Document 1 and the flying object protection plastic cover disclosed in Patent Document 2, it is believed that the scattering of cut weeds and gravel can be prevented to some extent. However, with the mower dust cover disclosed in Patent Document 1, when mowing the grass while moving forward or mowing while drawing an arc from side to side with the operator at the center, the dust cover may get caught on the ground. There is a risk.
また、特許文献２に開示された飛散物防護プラスチックカバーのうち、平板状の態様では周囲への飛散物の飛散を有効に防止することが困難であるものと思料する。一方、ポット型プラスチックカバーの態様では、飛散物の周囲への飛散は防ぐことができても、カバー内へ雑草を導入しにくいものと思料する。 Furthermore, among the flying object protection plastic covers disclosed in Patent Document 2, it is considered difficult to effectively prevent flying objects from scattering to the surroundings with a flat plate-like embodiment. On the other hand, in the case of a pot-shaped plastic cover, even if it is possible to prevent flying objects from scattering around the cover, it is thought that it is difficult to introduce weeds into the cover.
そこで本願発明者は、上記の問題点に鑑み、ナイロンコードを高速回転させることによって草刈り作業を行う草刈機用のカバーにおいて、雑草や砂利等の飛散物から作業者や草刈り作業が行われる場所に設置されている各種設備等を保護すると共に、草刈り作業の作業性の大幅な向上を図ることができる草刈機用カバーを提供するべく鋭意検討を重ねた結果、本発明に至ったのである。 In view of the above-mentioned problems, the inventor of the present application developed a cover for a mower that mowing work is performed by rotating a nylon cord at high speed, which protects the worker and the place where the mowing work is performed from flying debris such as weeds and gravel. The present invention was developed as a result of extensive research to provide a cover for a mower that can protect the various installed equipment and greatly improve the workability of mowing work.
即ち、本発明の草刈機用カバーは、ナイロンコードを高速回転させることによって草刈り作業を行う草刈機用のカバーであって、少なくとも、前記ナイロンコードを収容するナイロンカッター本体の上方、両側方及び後方を覆って取り付けられ、前方に開口部を備える可撓性のカバー本体と、前記カバー本体の両側方部の下端縁部に沿って各々配設されるソール部とを備え、前記ソール部の各々の前方部が、前記開口部の両側端に沿って上方にわん曲していることを特徴とする。 That is, the mower cover of the present invention is a cover for a mower that performs mowing work by rotating a nylon cord at high speed, and is at least above, on both sides, and behind the nylon cutter body that accommodates the nylon cord. a flexible cover body that is attached over the cover body and has an opening in the front; and sole parts that are respectively disposed along the lower edge of both side parts of the cover body, and each of the sole parts The front portion of the opening is curved upward along both side edges of the opening.
また、本発明の草刈機用カバーにおいて、前記カバー本体の両側方部の下端縁部及び後方部の下端縁部に沿って、可撓性の暖簾部材が配設されていることを特徴とする。 Further, in the lawn mower cover of the present invention, flexible curtain members are disposed along the lower end edges of both side parts and the lower end edge of the rear part of the cover main body. .
本発明の草刈機用カバーによると、ナイロンコードによって草刈り作業を行う際、刈り取った雑草や砂利等が周囲に飛散することを防止することができる。特に、可撓性のカバー本体が、ナイロンカッター本体の上方、両側方及び後方を覆って取り付けられるとともに、カバー本体の前方には開口部を備えるため、除草対象となる雑草を容易にカバー本体内へ導入することができる。また、ナイロンコードによって刈り取られた雑草や砂利等は、カバー本体によって周囲への飛散が防止される。従って、作業の安全性の向上が図られ、作業者を飛散物から有効に保護することができるとともに、草刈り作業が行われる場所に設置されている各種設備等も飛散物から保護することが可能となる。更には、飛散物から作業者や周辺設備を有効に保護することができるため、作業性の大幅な向上を図ることができる。 According to the mower cover of the present invention, when mowing work is performed using a nylon cord, it is possible to prevent cut weeds, gravel, etc. from scattering to the surrounding area. In particular, the flexible cover body is attached to cover the top, both sides, and rear of the nylon cutter body, and an opening is provided in the front of the cover body, so weeds to be weeded can be easily removed inside the cover body. It can be introduced into In addition, the cover body prevents weeds, gravel, etc. cut by the nylon cord from scattering to the surrounding area. Therefore, work safety is improved, and not only can workers be effectively protected from flying objects, but also various equipment installed in the area where grass mowing work is performed can be protected from flying objects. becomes. Furthermore, since workers and peripheral equipment can be effectively protected from flying objects, work efficiency can be significantly improved.
また、本発明の草刈機用カバーにおいて、カバー本体の両側方部の下端縁部に沿って各々ソール部が配設されているため、地面に接地させた状態でスライド移動させながら草刈り作業を行うことができ、作業性の向上を図ることができるとともに、地面とカバー本体との間に隙間ができにくくなり、雑草や砂利等の周囲への飛散防止効果も向上される。更に、ソール部の各々の前方部が、カバー本体の開口部の両側端に沿って上方にわん曲しているため、本発明の草刈機用カバーを地面に設置させた状態で前進しながら草刈り作業を行う場合でも、草刈機に係るナイロンカッター本体が地面に引っ掛かることを防止でき、作業性の更なる向上を図ることができる。 In addition, in the lawn mower cover of the present invention, the sole portions are arranged along the lower edge of both sides of the cover body, so mowing work can be performed while sliding the cover while it is in contact with the ground. This not only improves work efficiency, but also reduces the possibility of creating a gap between the ground and the cover body, and improves the effect of preventing weeds, gravel, etc. from scattering to the surrounding area. Furthermore, since each front portion of the sole portion is curved upward along both sides of the opening of the cover body, it is possible to mow the grass while moving forward with the mower cover of the present invention installed on the ground. Even when performing work, the nylon cutter body of the mower can be prevented from getting caught on the ground, and workability can be further improved.
また、本発明の草刈機用カバーにおいて、カバー本体の両側方部及び後方部の下端縁部に沿って、可撓性の暖簾部材を配設することによって、雑草や砂利等の飛散物から作業者や草刈り作業が行われる場所の周辺設備等を保護する効果が一段と高まる。更に、草刈機の作業角度が変わっても、地面と草刈機用カバー本体との隙間を暖簾部材によって塞ぐことができるため、飛散物の周囲への飛散防止効果をより一層向上することができる。 In addition, in the lawn mower cover of the present invention, by arranging flexible curtain members along both sides and the lower edge of the rear part of the cover body, it is possible to avoid flying debris such as weeds and gravel. This further enhances the effect of protecting people and surrounding equipment at the place where mowing work is performed. Furthermore, even if the working angle of the mower changes, the gap between the ground and the mower cover body can be closed by the curtain member, so that the effect of preventing scattered objects from scattering around the mower can be further improved.

FIG. 1 is a side view of a mower cover 10 according to an embodiment of the present invention, FIG. 2 is a front view of the mower cover 10, FIG. 3 is a rear view of the mower cover 10, and FIG. 4 is a mower cover 10. 3 is a plan view of the cover 10. FIG. 5 is a side view showing the mower cover 10 according to the present embodiment attached to the mower 11, and FIG. 6 is a longitudinal cross-sectional view of the X portion in FIG. 5, and the cross-sectional position is that of FIG. This is the position of line AA in the plan view.
これらの図に示すように、本実施形態の草刈機用カバー１０は、ナイロンコード１２を高速回転させることによって草刈り作業を行う草刈機１１用のカバーである。具体的には、まずナイロンコード１２を収容するナイロンカッター本体１４の上方、両側方及び後方を覆って取り付けられ、前方に開口部１８を備える可撓性のカバー本体１６と、このカバー本体１６の両側方部２０，２０の下端縁部２０ａ，２０ａに沿って各々配設されるソール部２２，２２とを備える。 As shown in these figures, the mower cover 10 of this embodiment is a cover for a mower 11 that performs mowing work by rotating a nylon cord 12 at high speed. Specifically, first, a flexible cover body 16 that is attached to cover the upper part, both sides, and the rear of the nylon cutter body 14 that accommodates the nylon cord 12 and has an opening 18 in the front; It includes sole portions 22, 22 disposed along lower end edges 20a, 20a of both side portions 20, 20, respectively.
図５及び図６に示すように、カバー本体１６内の上方には、草刈機１１に係るメインパイプ１３を固定するための固定台３０及び固定具３２が配設されている。カバー本体１６に設けられた貫通孔２６からメインパイプ１３を挿入し、メインパイプ１３の先端部を固定具３２によって固定台３０に固定することによって、草刈機１１のメインパイプ１３の先端部にカバー本体１６が取り付けられることとなる。そして、メインパイプ１３の先端にナイロンコード１２を収容するナイロンカッター本体１４を取り付けることによって、このナイロンカッター本体１４がカバー本体１６の上方、両側方及び後方によって覆われることとなる。 As shown in FIGS. 5 and 6, a fixing base 30 and a fixture 32 for fixing the main pipe 13 of the mower 11 are disposed above the cover body 16. By inserting the main pipe 13 through the through hole 26 provided in the cover body 16 and fixing the tip of the main pipe 13 to the fixing base 30 with the fixture 32, the cover is attached to the tip of the main pipe 13 of the mower 11. The main body 16 will be attached. By attaching the nylon cutter body 14 that accommodates the nylon cord 12 to the tip of the main pipe 13, the nylon cutter body 14 is covered above, on both sides, and at the rear of the cover body 16.
ここで、カバー本体１６内に配設されるメインパイプ１３の固定台３０の高さは特に限定されないが、図６に示すように、メインパイプ１３の先端側（ナイロンカッター本体１４の取り付け側）の高さｔ１を、メインパイプ１３の手前側（草刈機１１本体側）の高さｔ２より高くしておくことがより好ましい。メインパイプ１３の先端側の高さｔ１を、メインパイプ１３の手前側の高さｔ２より高くすることによって、メインパイプ１３を地面に対してある程度立てた状態でメインパイプ１３の先端部にカバー本体１６を取り付けることができ、作業者が草刈機１１を立った状態で使用する際に、カバー本体１６と地面との間の隙間をできにくくすることができる。 Here, the height of the fixing base 30 of the main pipe 13 disposed inside the cover body 16 is not particularly limited, but as shown in FIG.

It can be easily prevented. In particular, the flexible cover body 16 is attached to cover the top, both sides, and rear of the nylon cutter body 14, and has an opening 18 in the front of the cover body 16, so that the mower cover 10 can be placed on the ground. By moving the mower 11 forward while it is in contact with the ground, weeds to be weeded can be easily introduced into the cover body 16.
また、ナイロンコード１２によって刈り取られた雑草や砂利等は、カバー本体１６によって周囲への飛散が防止されるため、草刈り作業の安全性の向上が図られ、作業者を飛散物から有効に保護することができるとともに、草刈り作業が行われる場所に設置されている各種設備等（例えば、太陽光発電所における太陽光パネル等）も飛散物から保護することが可能となる。更には、飛散物から作業者や周辺設備を有効に保護することができるため、作業者は飛散物による被害を気にする必要が殆どなく、作業性の大幅な向上を図ることができる。 In addition, weeds, gravel, etc. cut by the nylon cord 12 are prevented from scattering to the surrounding area by the cover body 16, which improves the safety of mowing work and effectively protects workers from flying objects. At the same time, it is also possible to protect various equipment installed in the place where grass mowing work is performed (for example, solar panels in a solar power plant) from flying debris. Furthermore, since it is possible to effectively protect workers and peripheral equipment from flying objects, there is little need for workers to be concerned about damage caused by flying objects, and work efficiency can be greatly improved.
また、ナイロンカッター本体１４からナイロンコード１２を繰り出したい場合は、ナイロンカッター本体１４で地面を叩くことによって繰り出すことが可能であるが、ナイロンカッター本体１４が地面から少し浮いた状態であっても、カバー本体１６が可撓性を備えるため、カバー本体１６が撓むことによってナイロンカッター本体１４を地面に接触させることができ、ナイロンコード１２を容易に繰り出すことができる。更に、ナイロンコード１２を繰り出し過ぎた場合でも、ナイロンカッター本体１４の上方、両側方及び後方がカバー本体１６によって覆われているため、ナイロンコード１２がカバー本体１６の外側へはみ出すことがなく、雑草や砂利等の周囲への飛散を防止することができる。 Furthermore, if you want to feed out the nylon cord 12 from the nylon cutter body 14, you can do so by hitting the ground with the nylon cutter body 14, but even if the nylon cutter body 14 is slightly lifted off the ground, Since the cover body 16 is flexible, the nylon cutter body 14 can be brought into contact with the ground by bending the cover body 16, and the nylon cord 12 can be easily fed out. Furthermore, even if the nylon cord 12 is let out too much, the upper, both sides, and rear of the nylon cutter body 14 are covered by the cover body 16, so the nylon cord 12 will not protrude outside the cover body 16, and the weeds will be removed. It is possible to prevent the scattering of dirt, gravel, etc. to the surrounding area.
また、本実施形態の草刈機用カバー１０において、カバー本体１６の両側方部２０，２０の下端縁部２０ａ，２０ａに沿って各々ソール部２２，２２が配設されているため、地面に接地させた状態でスライド移動させながら草刈り作業を行うことができ、作業性の向上を図ることができるとともに、地面とカバー本体１６との間に隙間ができにくくなり、雑草や砂利等の周囲への飛散防止効果も向上される。 In addition, in the mower cover 10 of the present embodiment, the sole portions 22, 22 are disposed along the lower edge portions 20a, 20a of both side portions 20, 20 of the cover body 16, so that the sole portions 22, 22 are grounded on the ground. Mowing work can be carried out while sliding the cover in this state, which improves work efficiency. It also prevents gaps from forming between the ground and the cover body 16, and prevents weeds, gravel, etc. from getting into the surrounding area. The scattering prevention effect is also improved.
更に、ソール部２２，２２の各々の前方部２２ａ，２２ａが、カバー本体１６の開口部１８の両側端１８ａ，１８ａに沿って上方にわん曲しているため、本実施形態の草刈機用カバー１０を地面に接地させた状態で前進しながら草刈り作業を行う場合でも、草刈機１１に係るナイロンカッター本体１４やカバー本体１６が地面に引っ掛かることを防止でき、作業性の更なる向上を図ることができる。 Further, since the front portions 22a, 22a of the sole portions 22, 22 are curved upward along both side edges 18a, 18a of the opening 18 of the cover main body 16, the mower cover of this embodiment To further improve work efficiency by preventing the nylon cutter body 14 and cover body 16 of a mower 11 from getting caught on the ground even when mowing work is performed while moving forward with the mower 10 in contact with the ground.
