【考案の詳細な説明】〔産業上の利用分野〕本考案は、操縦ハンドルを備えた刈刃ハウジン
グの背面に、網状体からなる集草容器を取付けた
歩行型芝刈機に関する。[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a walk-behind lawnmower in which a grass collecting container made of a mesh body is attached to the back of a cutting blade housing equipped with a steering handle.

[Conventional technology]

一般に芝刈機の集草容器は、刈芝と共に送られ
てくるエアーを抜いて容器に対する刈芝の詰りを
良くするために、網状体によつて形成されている
のであるが、前記容器は、単に、容器製作の容易
性、経済性の観点から一つの布地、つまり、容器
の上面、背面、左右両側面、並びに底面が同一メ
ツシユによつて形成されていた（例えば、特開昭
61−111619号公報参照）。 Generally, the grass collection container of a lawn mower is formed of a net-like material in order to remove the air sent along with the grass clippings and to improve the clogging of the container with the grass clippings. From the viewpoint of ease and economy in manufacturing containers, the top, back, left and right sides, and bottom of the container were all made of the same mesh (for example,
61-111619).

[Problem that the invention attempts to solve]

容器の面に形成されるメツシユの大きさは刈芝
を逃がさないこと、そして、エアーを良く抜いて
容器に対する刈芝の詰りを良くすることの目的か
ら、刈刃ハウジングから送られて来る風量や容器
の大きさ等によつてある程度決まつている。 The size of the mesh formed on the surface of the container is determined by the amount of air sent from the cutting blade housing, in order to prevent the grass clippings from escaping, and to remove air well to prevent the grass clippings from clogging the container. It is determined to some extent by the size of the container, etc.

ところが、季節や地方等によつて乾燥度の異な
る芝、つまり、乾燥度合の大きい芝を刈取つた
時、芝が細かく粉砕されて、その粉砕された刈芝
が、容器の上面、背面を通つて操縦者側に吹き出
して来る欠点があつた。 However, when mowing grass whose dryness varies depending on the season or region, in other words, grass with a high degree of dryness, the grass is finely ground and the ground grass passes through the top and back of the container. There was a flaw in the pilot's side.

そこで、上記欠点を解消する手段として、実開
昭62−122524号公報に示されるように、エアーが
抜け出やすい多孔状の通気孔を容器上面の前部、
並びに、左右両側面の上部に設けて、前記エアー
が操縦者に当たらないようにすることが考えられ

アーの略全量を前記通気孔を介して排出しなけれ
ばならないことから、その通気孔のメツシユが比
較的大きなものとなつて刈芝が洩れ出し易くなる
不都合がある。 Therefore, as a means to eliminate the above-mentioned drawbacks, as shown in Japanese Utility Model Application Publication No. 62-122524, porous ventilation holes were installed in the front part of the upper surface of the container so that air could easily escape.
In addition, it is conceivable that the air be provided at the top of both the left and right sides to prevent the air from hitting the operator, but in such a case, almost all of the air from the cutting blade housing will be routed through the ventilation holes. Since the ventilation hole must be discharged, the mesh of the ventilation hole becomes relatively large, and there is an inconvenience that the grass clippings tend to leak out.

また、実開昭62−144430号公報に示されるよう
に、集草容器の上面及び背面に密着しない非通気
性カバーを設けて、前記集草容器の上面及び背面
から抜け出たエアーを、前記非通気性カバーによ
り左右両側方へ案内して操縦者にエアーが当たら
ないようにすることが考えられるが、斯かる場合
には、別途、非通気性カバーによりコストが高く
付く不都合がある。 Furthermore, as shown in Japanese Utility Model Application Publication No. 62-144430, an air-impermeable cover that does not come into close contact with the top and back surfaces of the grass collection container is provided to drain air that has escaped from the top and back surfaces of the grass collection container. It is conceivable to use a breathable cover to guide the air to both the left and right sides to prevent the air from hitting the operator, but in such a case, there is the disadvantage that a non-breathable cover is required, which increases the cost.

本考案は、刈芝の洩れ出しやコスト増大の抑制
をはかり乍ら粉塵が操縦者に降りかかることを抑
制することを目的とする。 The purpose of the present invention is to prevent dust from falling on the operator while suppressing leakage of grass clippings and cost increases.

[Means for solving problems]

上記目的を達成するための本考案の特徴構成
は、集草容器の左右両側面略全面を、上面及び背
面のメツシユよりも粗くした点にある。 A characteristic feature of the present invention for achieving the above object is that substantially the entire surfaces of both left and right sides of the grass collection container are made rougher than the mesh on the top and back surfaces.

[Effect]

刈刃ハウジングからのエアーは、上面及び背面
のメツシユよりも粗くされた左右両側面略全面を
介して抜け出ることから、左右両側面の上部や上
面の前部に局部的な多孔状の通気孔を設ける場合
に比して、エアー排出面積が大きくなり、その
分、メツシユの大きさを小さくでき、刈芝の洩れ
出しを抑制し得る。 Since the air from the cutting blade housing escapes through almost the entire surface of both left and right sides, which are rougher than the mesh on the top and back surfaces, local porous ventilation holes are provided at the top of both left and right sides and at the front of the top. Compared to the case where the air discharge area is provided, the air discharge area becomes larger, and the size of the mesh can be reduced accordingly, making it possible to suppress leakage of cut grass.

しかも、メツシユを使い分けてエアーの抜け方
を調整したから、集草容器の上面及び背面から抜
け出たエアーを、別途、非通気性カバーにより左
右両側方へ案内する場合に比して、非通気性カバ
ーが不要となる。 Moreover, since we have adjusted the way the air escapes by using different meshes, the air escape from the top and back of the grass collection container is not air-permeable, compared to the case where the air that escapes from the top and back of the grass collection container is guided to the left and right sides using separate non-air-permeable covers. No cover required.

[Effect of idea]

上記構成の結果、刈芝の洩れ出し、コスト増大
の抑制をはかり乍ら、粉塵が操縦者側に吹き出し
て来ることを抑制することができ、操縦者の作業
環境を悪化することがない。 As a result of the above configuration, it is possible to suppress the leakage of grass clippings and an increase in costs, and at the same time, it is possible to suppress dust from blowing out toward the operator, so that the working environment of the operator is not deteriorated.
