A multifunctional asphalt caulking machine

Abstract

The utility model discloses a multifunctional asphalt caulking machine, which relates to the technical field of caulking machines. The multifunctional asphalt caulking machine comprises a bottom plate, each fixing mechanism comprises an installation groove, an installation hole, a threaded rod, a threaded sleeve and a concave plate. By arranging a scraper, when the asphalt caulking machine moves, the scraper is installed at a suitable position according to the transportation direction of the asphalt caulking machine, and the pressure roller rotates with the asphalt caulking machine. At this time, the pressure roller compacts the asphalt, and the excess asphalt adheres to the outside of the pressure roller. At this time, as the pressure roller rotates, the asphalt on the pressure roller is scraped off by the scraper to prevent the asphalt attached to the compaction roller from drying on the outside of the compaction roller to cause uneven areas on the road surface, thereby avoiding affecting the uniformity of compaction. The protective cover provides protection for the discharge pipe so that the dust in the gap will not be blown into the inside of the discharge pipe by the blower head and mixed with the filling material, thereby avoiding affecting the performance of the filling material and reducing the bonding force between the asphalt and the road surface.

At this time, the scraper 3 is installed, and the pressure roller 2 rotates with the asphalt caulking machine. At this time, the pressure roller 2 compacts the asphalt, and the excess asphalt adheres to the outside of the pressure roller 2. At this time, as the pressure roller 2 rotates, the asphalt on the pressure roller 2 is scraped off by the scraper 3 to prevent the asphalt attached to the compaction roller from drying on the outside of the compaction roller, resulting in uneven areas on the road surface, thereby avoiding affecting the uniformity of compaction.

At this time, the staff can repair or clean the discharge pipe 12 to prevent the protective cover 17 from affecting the staff's operation of the discharge pipe 12.

[0029] Working principle:

[0030] The first step is to set the scraper 3 and the protective cover 17. Before the asphalt caulking machine works, the scraper 3 is installed in a suitable position according to the transportation direction of the asphalt caulking machine. At this time, the scraper 3 is inserted into the installation groove 5. At this time, the concave plate 9 is pushed so that one end of the concave plate 9 enters the interior of the installation hole 6 and the connecting hole 4. At this time, the threaded sleeve 8 is rotated so that the threaded sleeve 8 fits with the outside of the concave plate 9. At this time, the scraper 3 is installed, and the protective cover 17 is slidably connected to the outside of the discharge pipe 12. At this time, the protective cover 17 is pushed upward to be close to the limit plate 11. At this time, the plug plate 14 is pulled to make the plug plate 14 enter the interior of the slide groove 13. At this time, the protective cover 17 is pulled to fit with the limit plate 11. At this time, the plug plate 14 can be loosened. The plug plate 14 cannot slide under the restriction of the limit plate 11 until the protective cover 17 moves to the opening 15. At this time, the plug plate 14 slides out to the outside of the slide groove 13. At this time, the plug plate 14 enters the interior of the slot 16 through the opening 15. At this time, the protective cover 17 is installed.

[0031] In the second step, the pressure roller 2 rotates with the asphalt caulking machine. At this time, the pressure roller 2 compacts the asphalt. The excess asphalt adheres to the outside of the pressure roller 2. At this time, as the pressure roller 2 rotates, the asphalt on the pressure roller 2 is scraped off by the scraper 3 to prevent the asphalt attached to the compaction roller from drying on the outside of the compaction roller, causing uneven areas on the road surface, thereby avoiding affecting the uniformity of compaction. The protective cover 17 provides protection for the discharge pipe 12 so that the dust in the gap will not be blown into the inside of the discharge pipe 12 by the blower head and mixed with the filling material, thereby avoiding affecting the performance of the filling material and reducing the adhesion between the asphalt and the road surface.

[0032] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
