When the construction personnel uses the maintenance device, since the storage temperature of the asphalt and other filling materials is relatively high, the side where the storage box 201 is located is usually regarded as the front, and the maintenance device is pushed to move as a whole on the side where the installation side plate 102 is located. Therefore, in this structure, during the use of the maintenance device, the dust suction port 302 first contacts the pit and carries out cleaning work, and then the discharge port 202 is placed above the pit after cleaning, thereby carrying out the output of the asphalt and other filling materials, which ensures the rapid connection between cleaning and filling work, and improves the efficiency of maintenance work.

[0037] Preferably, as Figure 2As shown, the extension mounting frame 103 comprises a flat shelf plate 103-1 and an inclined support frame 103-2 arranged at the bottom of the flat shelf plate 103-1, one end of the inclined support frame 103-2 is fixedly connected with the flat shelf plate 103-1, and the other end is fixedly connected with the bottom end of the mounting side plate 102. Under this structure, while ensuring the stability of the extension mounting frame 103 itself, the inclined support frame 103-2 forms an avoiding structure, so as to facilitate the construction personnel to observe the cleaning effect of the dust removal part 3 and the material output condition of the material conveying part 2, and then quickly adjust the development of the maintenance work according to the actual working condition, etc., such as whether it is necessary to carry out secondary dust removal and cleaning work, whether it is necessary to lay another layer of filling material, etc.

[0038] Finally, it should be noted that: the above implementation cases are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing implementation cases, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing implementation cases, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the implementation cases of the present application.
