Description

[Detailed explanation of the invention] [Purpose of the invention] (Field of industrial application) This invention is designed to enable, for example, a dump truck to run without muddy water leaking from water-containing gravel loaded on the platform of a dump truck to the outside. This invention relates to a cargo platform structure for a luggage vehicle with an improved structure.

(Prior Art) Conventionally, when wet gravel, sand, etc. are loaded onto the loading platform of a dump truck or the like, a large amount of muddy water or the like flows out of the loading platform through gaps between the loading platform and the rear gate. Therefore, there are problems such as muddy water staining the road surface while the vehicle is running, and causing trouble to other vehicles or drivers.

(Problem to be solved by the invention) This invention was made by paying attention to the above-mentioned situation. Even when wet gravel, etc. is loaded on the loading platform, muddy water, etc. that flows out from the loaded object will flow out from the loading platform while the vehicle is running. It is an object of the present invention to provide a loading platform structure for a luggage vehicle that can prevent the cargo from flowing out.

[Structure of the idea]

(Means and effects for solving the problem) This invention consists of a loading platform with a plurality of drainage ports provided at the bottom, and a loading platform installed at the bottom of the loading platform to receive water from the drainage ports and to direct the drainage in a predetermined direction. a waterway that extends in the vehicle width direction, is located on the upstream side of the waterway, communicates with the waterway, and receives waste water that has passed through the rear gate and leaked out of the loading platform;
It is equipped with a collection part located on the downstream side of the waterway where wastewater flowing in the waterway is collected, and an external drainage valve installed in this collection part to prevent muddy water etc. from flowing out from the loading platform while traveling. This is what I did.

(Embodiment) An embodiment of this invention will be described below with reference to FIGS. 1 to 4. In Fig. 2, 1 is the body of a luggage vehicle, and at the rear of the upper part of the vehicle body 1 is provided a box-shaped loading platform 2 with an open top and rear portion. The upper part of the rear gate 3, which is opened when lowering the vehicle, is attached to a hinge 4 so as to be rotatable rearward. Further, as shown in FIG. 1, a plurality of drainage ports 5 are formed in a row from the front to the rear of the loading platform 2 on the entire bottom of the loading platform 2. Further, in the lower part of the loading platform 2 corresponding to each of the drain ports 5, there are a plurality of gutter-shaped waterways 6 having a downward slope from the rear to the front.
...is provided. A collecting portion 7 is provided at the front end of these water channels 6 in the width direction of the vehicle body 1. Drainage port bodies 7a, 7a are provided at the bottom of both left and right ends of this collecting portion 7, and a drain valve 8 for preventing drainage from flowing out is attached to these drainage port bodies 7a, 7a as shown in FIG. ing.
Further, a hose 10 is attached to the lower part of the drain valve 8. Furthermore, at the rear end of the water channel 6 shown in FIG. 1, that is, at the bottom of the rear gate 3, a receiving water channel 9 is provided across the width direction of the vehicle at a position where it can receive the waste water flowing out from the gap in the rear gate 6. There is. The receiving water channel 9 is connected to the water channel 6..., and the receiving water channel 9 and the water channel 6... are in communication with each other. Next, referring to Figure 4, drain port 5
To explain the nearby structure, each of the above drainage ports 5
A fixing frame 13 is provided on the edge of the bottom 11 of the loading platform 2, and these fixing frames 1
A wire mesh filter 12 covering the drain port 5 is stretched over the drain port 3 . When wet gravel or the like is loaded on the loading platform 2, muddy water or the like flowing out from the loaded material passes through the filter 12 from the drain port 5 and only water flows into the water channel 6. is collected in the collecting portion 7 due to the slope of the water channel 6. In addition, the drainage water leaking from the gap between the rear gate 3 and the bottom of the loading platform falls into the receiving channel 9 and then flows into the channel 6.
It is guided to the collection section 7 through...

In this way, by providing a drainage waterway in the lower part of the loading platform 2, it is possible to prevent a large amount of drainage from flowing out from the rear gate 3. Also, rear gate 3
Since the drainage water leaking from the gap can be received by the water receiving channel 9, it is possible to solve problems such as soiling the road surface due to drainage water flowing out from the rear gate 3. Furthermore, by providing a drain valve 8 at the lower part of the collection section 7, it is possible to prevent the drainage water from flowing out while the vehicle is running, and by opening the drain valve 8 when the vehicle has arrived at the destination and stopped. , drainage can be done at designated locations. Furthermore, by attaching the hose 10 to the drain valve 8, it is possible to prevent the waste water from scattering when water is discharged. In addition, since the water channel 6... is sloped low from the rear of the vehicle to the front, muddy water leaking from the gravel inside the loading platform 2 is guided from the drain port 5... to the water channel 6... side, and is directed toward the rear gate side. It is suppressed from being led to. Therefore, excessive muddy water or the like does not leak out from the gap between the rear gate 3 and the bottom of the cargo platform 2.

Furthermore, even if muddy water or the like leaks from the gap between the rear gate 3 and the bottom of the loading platform 2, this muddy water is guided from the receiving channel 9 to the water channel 6 and then to the collecting section 7, so that the muddy water, etc. leaks onto the road surface, etc. outflow can be suppressed as much as possible. At this time, by suppressing the amount of muddy water etc. guided to the rear gate 3 side, the receiving channel 9
This has the advantage that it can be made small.

In addition, a collecting section 7 is provided at the end of the water channel 6 on the other side of the receiving channel 9, and the water channel is sloped so that the waste water flows into the collecting section 7, and the water channel 6... Since the receiving channel 9 is connected to the receiving channel 9, drainage such as muddy water on the receiving channel 9 side is quickly removed, and the receiving channel 9 is also effectively prevented from flowing out onto the road surface.

In addition, although the drain ports 5 are provided in a row in the above embodiment, the present invention is not limited to this. Also,
The water channel 6 is not limited to the above shape.
Furthermore, the filter 12 is not limited to a wire mesh, but may have any mesh structure that allows only the water contained in the load to pass through. Further, when the loading platform has a swell, by providing a receiving channel below the swell portion to receive leaked water, it is possible to prevent the water from flowing out to the outside as described above. Furthermore, this invention is not limited to dump trucks and can be applied to other cargo vehicles.

[Effect of idea]

As described above, this invention can significantly reduce the large amount of water that leaks from gaps such as the rear gate by providing a drainage port at the bottom of the cargo platform. Furthermore, by closing the drain valve while the vehicle is running, it is possible to prevent waste water from flowing outside, thereby eliminating problems such as staining the road surface and causing trouble to other vehicles and pedestrians. In addition, the waste water collected during travel can be drained to a predetermined location by opening the drain valve after reaching the destination.

In addition, a receiving channel is provided on the upstream side of the waterway to receive wastewater that has passed through the rear gate and leaked out of the loading platform, and since this receiving channel communicates with the waterway, it is possible to prevent wastewater from flowing out onto the road surface, etc. can.
