And then stored in the sewage tank 15 through a pair of right and left water pipes P. Then, the stored sewage in the sewage tank 15 is discharged to the outside from the drain outlet 20 by opening the sewage lid 21.

  By the way, in the dust disposal process by the dust collection vehicle, the dust collected in the dust storage box 1 is discharged to a pit or the like of the dust treatment facility. Before discharging the dust, it is necessary to raise the dust input box 6 rearwardly (the position of the chain line in FIG. 1) to open the rear wall 2 of the dust storage box 1. At that time, the sewage in the sewage tank 15 Is drained to the outside through the water guide pipe P and the sewage basin 13, and the sewage flowing in the water guide pipe P at that time is applied to the inclined surface 17 as shown by a two-dot chain line arrow b in FIGS. Along the inside of the vehicle, can be dropped on the platform of the garbage disposal facility, and can rush toward the inside and hit the ground to scatter much inside, so that the sewage is less likely to splash outside the vehicle . This makes it difficult for the cleaners on the left and right sides of the garbage truck to get sewage.

  In order to immediately clean the platform of the dust disposal facility after the dust is discharged by the garbage truck V, the cleaner may wait on the side of the garbage truck V until the dust is completely discharged.

  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 are wrapped in the vertical direction, the sewage in the sewage tank 15 is introduced into the water during a sudden stop while the vehicle is running. When backflowing into the pipe P, the sewage can be blocked by the backflow prevention plate 18 and the lower wall surface 16d.

  Further, as shown by a two-dot chain line arrow in FIG. 3, the backflow prevention plate 18 provided in the water guide pipe P can easily guide the sewage flowing from the sewage tank 15 into the water guide pipe P to the inclined surface 17. It is possible to assist discharge of sewage discharged in an oblique direction while ensuring the width of the inlet of the water guide pipe P. The backflow prevention plate 18 can combine the function of preventing the backflow of sewage during a sudden stop while the vehicle is traveling and the function of assisting the drainage of the sewage in an oblique direction when the dust box 6 is turned upright.

  The inclined surface 17 can guide the sewage flowing backward in the water guide pipe P toward the inside of the vehicle and drop it on the platform of the refuse treatment facility, and the backflow prevention plate 18 is inclined from the water guide pipe P to the inclined surface 17. By acting so as to guide the sewage that falls straight without falling to the inclined surface 17, the sewage can be guided by the inclined surface 17.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to that embodiment, A various embodiment is possible within the scope of the present invention.

  For example, the inclined surface may be formed by inclining the outer vertical wall surface of the water guide pipe inward. Moreover, one or three or more water guide pipes may be provided. The water guide pipe may not have the backflow prevention plate and the lower wall surface. Further, the loading device provided in the dust box is not limited to that of the above embodiment.
