Then, the liquid flows down uniformly and accumulates at the coating material outlet 7.

Next, when the coating material outlet shutter 8 is opened, the second coating material blocking shutter 13 is rotated and opened, and then the first coating material blocking shutter 10 is rotated and opened. The coating material 4 uniformly and quantitatively flowed down by the rotating bodies 1 and 2 is moved downward in the cylindrical brush rotating body 1.
Due to the rotation of the rotating body 2 and the cylindrical drum 2, centrifugal force and repulsion force and the like cause the two rotating bodies 1 and 2 to be uniformly atomized and sprayed to hit the road surface GL, thereby bonding the coating film 16. And uniform road sign painting can be performed.

At the end of coating with the coating material outlet shutter 8 closed, the coating material is blocked from flowing into both rotating bodies, and the injection by both rotating bodies 1 and 2 is blocked. The outflow of the material 4 stops, and the road marking painting can be stopped. At this time, the first coating material blocking shutter 10 and the second coating material blocking shutter 13
Are provided so that they are fully closed almost simultaneously.
The coating material dripping from both rotating bodies is received by the second coating material shut-off shutter 13 heated by the second burner 15,
Further, it is received by the first coating material blocking shutter 10. Accordingly, the opening 16 of the first coating material blocking shutter 10 and the second coating material blocking shutter 13 allows the coating film 16 to be adhered to the road surface.

Here, on both lower sides of the hopper 3, covers 5 and 6 for the rotating bodies are provided along the outer circumferences of the rotating bodies 1 and 2, respectively. Is provided above, and the lower extending end portions 5b, 6b of the cover portions 5, 6 of the two rotating bodies are provided so as to be opposed to and separated from each other at a predetermined interval. As shown in FIG. 2, the coating material 4 which is atomized and sprayed by the bodies 1 and 2 has a high density, a constant thickness, and is adhered on a road surface with a reduced coating width t. At this time, the leading end and the trailing end of the coating width are finely finished with little jaggedness.

In particular, the present invention is most suitable for forming a broken line. When forming the broken line, first, the coating material outlet shutter 8 is opened, and the coating material shut-off shutter 10 is opened and rotated. , The coating material 4 is sprayed (4a) and struck against the road surface GL to adhere the coating film 16 to perform uniform road marking painting.
At the same time that the coating material outlet shutter 8 is closed, the first coating material blocking shutter 10 and the second coating material blocking shutter 13 are closed and rotated to the state shown in FIG. This operation is repeated to continuously form a broken line. Therefore, it is possible to form the leading and trailing portions of the broken line neatly without applying a tape to the leading and trailing portions of the broken line and spraying the tape as in the related art, and then removing the tape. .
