に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a grass collecting container with its front wall connected to a grass supply tube that supplies grass by air blowing from the cutting blade housing. The present invention relates to a structure of a grass collecting section of a lawn mower, which is provided with a first wind exhaust section on a wall and a first guide that guides the wind from the first wind exhaust section downward into the machine body.

〔従来の技術〕[Conventional technology]

前記芝刈り機は、前記第１ガイドの作用によ
り、集草容器から排出風と共に出る塵埃が集草容
器の上方に舞い上がることの抑制を図るように構
成されたものである。 The lawn mower is configured to suppress dust coming out of the grass container together with the exhaust air from flying up above the grass container by the action of the first guide.

この種芝刈り機において、従来、塵埃飛散の抑
制のために、芝供給風の集草容器からの排出が集
草容器の前壁のみから行われるようになつてお
り、次の如き不利があつた。 Conventionally, in this type of lawn mower, in order to suppress dust scattering, the turf supply air is discharged from the grass collection container only from the front wall of the grass collection container, which has the following disadvantages. Ta.

〔考案が解決しようとする課題〕[The problem that the idea attempts to solve]

すなわち、回収芝は送風に乗つて運ばれるの
で、集草容器には風の排出部を設けておく必要が
あり、前述した塵埃の飛散防止の観点と相まつて
前壁にのみ排風部を設けていたが、芝回収に伴う
排風部の目詰まりによる排風面積の減少によつて
排風不良となる状態が比較的早期に現れ、集草容
器の容積の割りには回収芝量が少ない不都合があ
つた。 In other words, since the collected grass is carried by the blast of air, it is necessary to provide a wind exhaust part in the grass collection container.In conjunction with the above-mentioned viewpoint of preventing dust scattering, it is necessary to provide a wind exhaust part only on the front wall. However, due to the reduction of the air exhaust area due to clogging of the air exhaust section during grass collection, a condition of poor ventilation appeared relatively early, and the amount of grass collected was small compared to the volume of the grass collection container. There was an inconvenience.

つまり、回収初期では集草容器内の後部にも十
分送風されて芝が蓄積されるのであるが、回収芝
量が増えてくるに従つて容器内部の空間形状が前
後長さの長いものに変化し、その結果、次第に容
器内後部に送風が回り込めないようになつて容器
内上部に未回収空間が残つてしまうのである。 In other words, in the early stages of collection, sufficient air is blown to the rear of the grass collecting container and grass is accumulated, but as the amount of collected grass increases, the shape of the space inside the container changes to a longer length from front to back. As a result, the air gradually becomes unable to reach the rear part of the container, leaving an unrecovered space in the upper part of the container.

本考案の目的は、芝供給風の排風とともに排出
される塵埃の舞い上がりを抑制できるようにしな
がら回収可能な芝量の増大化を図る点にある。 An object of the present invention is to increase the amount of grass that can be collected while suppressing the dust that is discharged with the exhaust of the grass supply wind.

〔課題を解決するための手段〕[Means to solve the problem]

上記目的を達成するために本考案は、集草容器

ドを設けてあることを特徴とする。 In order to achieve the above object, the present invention provides a grass collection container with a front wall connected to a grass supply tube that supplies grass by air blowing from a cutting blade housing, and at least the upper side of the grass supply tube of the front wall In the grass collection part structure of a lawn mower, which is provided with a first wind exhaust part and a first guide that guides the wind from the first wind exhaust part downward into the machine body, a flat surface is provided on the upper wall of the grass collection container. A second wind exhaust part is provided around the upper wall part, which is located near the upper part of the discharge port of the turf supply tube when viewed from the outside, and a second
It is characterized by being provided with a second guide that guides the wind from the wind exhaust section downwards into the fuselage.

〔作用〕[Effect]

前記特徴構成によれば、上壁にも排風部を設け
たことによつて芝回収の終期における芝の容器内
後部への回り込み不能現象が緩和され、容器内上
部にも芝を回収可能となる。 According to the above-mentioned characteristic configuration, by providing an air exhaust part on the upper wall, the phenomenon in which the grass cannot go around to the rear part of the container at the final stage of grass collection is alleviated, and grass can also be collected in the upper part of the container. Become.

そして、その上壁での第２排風部を、平面視で
芝供給筒の吐出口の付近に位置する上壁部分を除
いてその周部に設けたことにより、第２排風部か
らの風の抜け出しがある間には芝供給筒の吐出口
付近に極力芝が堆積しないようになつて、容器内

堆積した芝によつて第２排風部からの排風が不能
になると、第１排風部の排風作用が生じ、これに
よつて芝供給筒の吐出口付近にも芝が堆積される
ようになる。 By providing the second wind exhaust section on the upper wall around the periphery of the upper wall except for the upper wall portion located near the discharge port of the turf supply tube in plan view, the second wind exhaust section from the second wind exhaust section is provided. While the wind is escaping, grass is prevented from accumulating near the discharge port of the grass supply tube as much as possible, and grass is accumulated from around the inside of the container. and,
When it becomes impossible to exhaust air from the second air exhaust part due to the accumulated grass, the air exhaust action of the first air exhaust part occurs, and as a result, grass is also accumulated near the discharge port of the grass supply tube. It becomes like this.

つまり、第１及び第２排風部の相互作用によつ
て、回収芝量を従来に比べて増大させることがで
きるのであり、単に上壁に排風部を設ける手段に
比べて、芝回収量をより増加させることができる
ようになる。 In other words, the amount of grass collected can be increased by the interaction between the first and second ventilation parts compared to the conventional method, and the amount of grass collected can be increased compared to the method of simply providing the ventilation part on the upper wall. It will be possible to increase the amount more.

また、第２ガイドの新設により、第２排風部か
ら出る排風も機体下方へと案内されるようにな
り、塵埃の舞い上がりを抑制するようになる。 In addition, by newly installing the second guide, the exhaust air coming out of the second exhaust part is also guided to the lower part of the fuselage, thereby suppressing the flying up of dust.

〔考案の効果〕[Effect of idea]

その結果、前壁の第１排風部とは別に上壁に設

業中断回数を減少できて作業能率が向上するよう
にできた。 As a result, by designing the shape of the second air exhaust part and the second guide, which are installed on the upper wall separately from the first air exhaust part on the front wall, it is possible to effectively prevent dust from flying up in the grass collection container where the grass is fed from the front wall. We were able to create a grass collection structure that can greatly increase the amount of grass collected while preventing damage, reducing the number of work interruptions and improving work efficiency.
