The body is installed so as to be movable in the length direction X of the bed, a bar connected to the traveling body is erected in the width direction Y of the bed, and the holding body for holding the neck portion of the discharge nozzle of a fluid such as earth and sand is the bar. Movably in the length direction, the tip of the discharge nozzle can be moved in any of the X and Y directions on the surface of the carrier, and a traveling body that runs across the upper end of the carrier side plate at the rear end. A moving device 35 is provided, and the holding body is moved through the entirety of the discharge nozzle 33 by penetrating and holding the rear of the discharge nozzle with the traveling body. The discharge nozzle is connected between the holding body and the traveling body 35c. The space between the discharge nozzle and the It is an Abstract that it has possible to cope with the movement of the end portion.

[0008]

According to the present invention, the discharge nozzle for the fluid such as earth and sand is held by the holding body, and the fluid such as the earth and sand discharged from the tip of the nozzle is mounted on the car bed. By moving along the platform, the platform can be moved in the width direction Y. Further, since this bar is connected to a traveling body installed so as to straddle a rail provided along the loading platform side plate, the bar can move in the length direction X of the loading platform along with the movement of the traveling vehicle. At this time, the traveling body can stably move by the simple structure of being installed so as to straddle the rail.
As described above, the holding body can freely move in both the X and Y directions on the surface of the bed via the traveling body and the bar, so that the discharge nozzles held by the holder can also face every corner of the bed. It is possible to discharge a fluid such as earth and sand while moving, and to quickly load a uniform height.
