A paint container that is supported so as to be immovable in the horizontal direction and movable in the vertical direction, receives the road surface paint in a flowing state, and allows the road surface paint to flow out from a slit-shaped bottom opening extending in the width direction of the vehicle body, There has been proposed a road surface paint application apparatus of a type in which the road surface paint is applied to a road surface with a thickness and a predetermined width dimension corresponding to a gap between the bottom of the paint container and the road surface.

[0003] The above-mentioned road paint application apparatus is usually
In order to change the height position of the member on the traveling direction of the pair of members constituting the slit-shaped bottom opening of the paint container, that is, the thickness position of the film thickness adjusting plate, in order to adjust the application thickness of the road surface paint, for example, , A screw member connected to the film thickness adjusting plate, a film thickness adjusting nut screwed into the screw member to adjust the height position of the film thickness adjusting plate, and a lock nut for preventing loosening of the film thickness adjusting nut. Is provided.

[0004]

In the work of applying road paint, there is a case where the thickness of the road paint applied must be frequently changed in connection with overpainting or the like. However, in the conventional film thickness adjusting device of the road surface paint application device, the film thickness adjusting device is provided at the bottom of the paint container, and the film thickness adjusting device is fixed to the vehicle body adjacent to the downstream side of the paint container. The lock nut and the film thickness adjusting nut of the film thickness adjusting device in a state in which the road surface paint application device is turned over or the glass bead spraying device is removed from the vehicle body because the glass bead spraying device is positioned on the side of the glass bead spraying device. And it was extremely difficult to change the thickness of the road surface paint applied during the operation. Also, during the work, the paint container is heated using a gas burner to maintain the fluidity of the road surface paint, so it is necessary to operate a high-heat film thickness adjusting device. It was a difficult task to change the coating thickness of the paint for home use.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a road surface paint coating which can easily change the coating thickness even during the road surface paint application operation. It is to provide a device.

[0006]

The movable side plate 80 and the paint container 28
Is changed in the height direction, and the gap between the slide edge 54 at the bottom of the paint container 28 and the road surface 36 changes, so that the film thickness T of the road surface paint 42 applied on the road surface 36 is reduced. Newly set. At this time, when changing the coating film thickness T of the road surface paint 42, it is not necessary to turn the road surface paint application device 10 over or to remove the glass bead scattering device 30 from the vehicle body. Further, even if the paint container 2 is
