〔産業上の利用分野〕
本発明は路面清掃車、詳しくは真空式の路面清掃車に関
する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a road cleaning vehicle, and more particularly to a vacuum type road cleaning vehicle.
従来、出願人によって真空式路面清掃車として塵埃収容
タンクからブロアへの通路に回転可能なフィルタードラ
ムを設け、さらに清掃空気がフィルタードラム内から塵
埃収容タンク側に吹出するように構成したものが提供さ
れている（特開昭６０−２２８７０１号公報参照）。Conventionally, the applicant has provided a vacuum road cleaning vehicle in which a rotatable filter drum is provided in a passage from a dust storage tank to a blower, and cleaning air is blown out from inside the filter drum toward the dust storage tank. (See Japanese Unexamined Patent Publication No. 60-228701).
上記従来の真空式路面清掃車は路上の塵埃を確実に吸引
し、かつ吸引した塵埃と空気を確実に分離し、塵埃収容
タンクに収容することを目的とし、具体的には比重が軽
く塵埃収容タンクに落丁しない微小塵埃をフィルタード
ラムで捕捉し、空気のみを外部に排出しようとするもの
である。The purpose of the conventional vacuum road cleaning vehicle mentioned above is to reliably suck up dust from the road, separate the sucked dust from air, and store it in a dust storage tank. The purpose is to use a filter drum to capture fine dust that does not fall into the tank, and to exhaust only air to the outside.
しかしながら、上記フィルターによる微小塵埃の捕捉に
も自ずと限界がある。However, there is a limit to the amount of fine dust that can be captured by the filter.
すなわち、真空式路面清掃車においては塵埃の種類、吸
引力の低下等の理由とより高性能フィルターは使用でき
ないためである。In other words, this is because high-performance filters cannot be used in vacuum road cleaning vehicles due to the type of dust, reduced suction power, etc.
本発明は上記事情に鑑みてなされたものであり、上記微
小塵埃をさらに捕捉し、外部に空気のみを排出しようと
するものである。The present invention has been made in view of the above circumstances, and aims to further capture the fine dust and exhaust only the air to the outside.
本発明は上記課題を解決するため、路面上の路面清掃車
において、塵埃収容タンクからブロアへの通路に開口部
を塵埃収容タンク側とした口字状の邪魔板が千鳥状に、
且つ底板を貫通して起立状態に設けられ、該邪魔板貫通
部の塵埃収容タンク側底板部にそれぞれ落下孔が設けら
れ、底板下方に集塵タンクが設けられた構成としたもの
である。In order to solve the above-mentioned problems, the present invention provides a road cleaning vehicle on a road surface, in which a cross-shaped baffle plate with an opening on the dust storage tank side is arranged in a staggered manner in the path from the dust storage tank to the blower.
In addition, the baffle plate is provided in an upright state through the bottom plate, drop holes are provided in the bottom plate portion on the dust storage tank side of the baffle plate penetrating portion, and a dust collection tank is provided below the bottom plate.
清掃開始とともに、ブロア（８）が作動させられるとサ
イトガツタ−ブラシ（３０）等で集められた塵埃が吸込
管（２）によって吸引され、吸込管（区の開口部【４）
から塵埃収容タンク（３）内に供給される。When cleaning starts, the blower (8) is activated, and the dust collected by the sight gutter brush (30) etc. is sucked by the suction pipe (2), and the dust is sucked into the suction pipe (opening [4) of the suction pipe (section).
is supplied into the dust storage tank (3).
この時、気流が急に遅くなるため大部分の塵埃は塵埃収
容タンク（３）内に落下収容される。そして、比重が軽
く、落下しない微小塵埃は気流にのりフィルタードラム
部）の周面に達し捕捉され空気のみがフィルタードラム
（５）を経由してブロア（８）の働きで通路（７）に吸
引される。この段階で微小塵埃のほとんどが除去されて
いる。At this time, since the airflow suddenly slows down, most of the dust falls and is contained in the dust storage tank (3). Microscopic dust that has a light specific gravity and does not fall is carried by the air current and reaches the circumferential surface of the filter drum section (filter drum section), where it is captured and only the air is sucked into the passage (7) by the blower (8) via the filter drum (5). be done. At this stage, most of the fine dust has been removed.
さらに通路（７）に至ると、そこに設けられた邪魔板（
１２）に衝突させられ、該邪魔板（１２）を迂回した状
態で下流へと流され、そこに含まれていた極小塵埃等は
迂回を阻止された状態で底板（１３）に設けられた落下
孔（１４）部から下方の集塵タンク（１５）に落下させ
られるものである。Further, when you reach the passage (7), there is a baffle board (
12) and flowed downstream, bypassing the baffle plate (12), and the minute dust contained therein was prevented from bypassing the baffle plate (13). The dust is dropped from the hole (14) into the dust collecting tank (15) below.
上記本発明の邪魔板（１２）は塵埃収容タンク（３）側
、すなわち、上流側が開口された口字状に構成されてい
る。The baffle plate (12) of the present invention is configured in a mouth shape with an opening on the dust storage tank (3) side, that is, on the upstream side.
したがって極小塵埃を含んだ空気が衝突するとその両側
を逆戻り状態で迂回しなげればならないものである。Therefore, when air containing extremely small particles collides with each other, it has to go around both sides in a backward state.
その過程で、極小塵埃が空気と分離され、落下孔（１４
）から集塵タンク（１５）に落下させられるものである
。また、本発明では上記邪魔板（１２）を通路（７）に
千鳥状に設けている。In the process, microscopic dust is separated from the air and the drop hole (14
) into the dust collection tank (15). Further, in the present invention, the baffle plates (12) are provided in a staggered manner in the passage (7).
したがって、極小塵埃を含んだ空気は必ず邪魔板（１２
）に衝突するものであり、ストレートにブロア（８）に
至ることがなく、集塵効果が高められるものである。Therefore, the air containing extremely small dust must be kept away from the baffle plate (12
), the dust does not reach the blower (8) straight, and the dust collection effect is enhanced.
上記のごとくして集塵タンク（１５）に捕捉された極小
塵埃は適時に排出扉（３１）をあけて取り出され廃棄さ
れる。The extremely small dust trapped in the dust collection tank (15) as described above is removed and discarded by opening the discharge door (31) in a timely manner.
