Description

上記目的を達成するために、本請求項１記載の発明は、車体フレーム上に、塵芥収容箱を搭載し、該塵芥収容箱の開口後壁に、塵芥投入箱を後方に起伏回動可能に設け、塵芥投入箱に投入された塵芥を、塵芥収容箱内に押込収容するようにした塵芥車において、
塵芥投入箱には、収容塵芥からでる排出汚水を受け入れる汚水樋と、その汚水樋内の汚水を溜める汚水タンクと、塵芥投入箱の縦中心線から左右方向のいずれか一方に偏った位置で、汚水樋と汚水タンクとを連通する導水パイプとが設けられ、
導水パイプには、塵芥投入箱の起立回動時に、汚水タンクから汚水樋へ逆流する汚水を、車体フレームの左右方向内側に導く傾斜面が設けられるとともには、塵芥車の走行時に汚水が汚水樋に逆流するのを協働して防止するための導水パイプの下壁面と逆流防止板とが、塵芥投入箱の縦中心線と直交する方向にそれぞれ延びるようにして設けられることを特徴としている。
In order to achieve the above object, the invention according to claim 1 mounts a dust storage box on a vehicle body frame, and allows the dust storage box to undulate and rotate backward on the rear wall of the opening of the dust storage box. In a garbage truck that is provided so that the dust thrown into the dust input box is pushed and stored in the dust storage box.
The dust input box has a sewage gutter that receives the discharged sewage from the stored dust, a sewage tank that collects the sewage in the sewage gutter, and a position that is biased to the left or right from the vertical center line of the dust input box. A drainage pipe that connects the sewage gutter and the sewage tank is installed.
The water guide pipe is provided with an inclined surface that guides the sewage flowing back from the sewage tank to the sewage gutter when the dust input box is upright and rotated inward in the left-right direction of the vehicle body frame. It is characterized in that a lower wall surface of a water guiding pipe and a backflow prevention plate for cooperatively preventing backflow are provided so as to extend in directions orthogonal to the vertical center line of the dust input box .

上記目的を達成するために、本請求項２記載の発明は、前記請求項１に記載のものにおいて、前記導水パイプの下壁面は、前記汚水タンクの壁面を延長して設けられていることを特徴としている。
To achieve the above object, the invention of this second aspect, there is provided a connector described in claim 1, the lower wall surface of the water guide pipe, a Tei Rukoto provided by extending the wall surface of the sewage tank It is a feature.

本請求項１，２記載の発明によれば、塵芥収容箱内の収容塵芥を排出する前に、塵芥投入箱を後方に起立回動させた時に、導水パイプ内を流れる汚水を、導水パイプに設けた傾斜面に沿って車両の内側に向かって流して、塵芥処理施設のプラットホーム上に落下させることができ、車両の外部に飛び散りにくくし、塵芥車の左右に居る清掃者に汚水がかかることを抑制することができる。
According to the inventions described in claims 1 and 2 , the sewage flowing in the water guide pipe is transferred to the water guide pipe when the dust input box is upright and rotated backward before the stored dust in the dust storage box is discharged. It can flow toward the inside of the vehicle along the provided slope and drop it on the platform of the garbage truck, making it difficult for it to scatter outside the vehicle, and the cleaners on the left and right of the garbage truck will be exposed to sewage. Can be suppressed.

図３に示すように、逆流防止板１８の右端と導水パイプＰの下壁面１６ｄの左端とが上下方向でラップしているため、車両走行時中の急停止時に汚水タンク１５内の汚水が導水パイプＰ内に逆流するとき、逆流防止板１８と下壁面１６ｄとの協働で汚水をせき止めることができる。
As shown in FIG. 3, since the right end of the backflow prevention plate 18 and the left end of the lower wall surface 16d of the water guide pipe P wrap in the vertical direction, the sewage in the sewage tank 15 is guided when the vehicle suddenly stops while traveling. when flowing back into the pipe P, it is possible to dam the sewage in cooperation with the check plates 18 and the lower wall 16d.

たとえば、傾斜面は、導水パイプの外側縦壁面自体を内側に傾斜して形成してもよい。また、導水パイプは一つあるいは三つ以上であってもよい。さらに塵芥投入箱内に設けられる積込装置は、前記実施形態のものに限定されない。
For example, the inclined surface may be formed by inclining the outer vertical wall surface itself of the headrace pipe inward. Further, the number of water conveyance pipes may be one or three or more . Of loading device provided in the dust-up box to et al it is not limited to the above embodiment.
