All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Embodiment 1

[0030] See also Figure 1-Figure 11 The utility model provides a technical solution: an asphalt conveying device for asphalt pavement construction, comprising a support frame 1, a heating box 3 is installed on the top of the support frame 1, a conveyor belt 4 is arranged in the middle of the support frame 1, a rotating shaft 8 is arranged on the left and right sides of the conveyor belt 4, one of the pulleys 6 is installed at the rear end of the left rotating shaft 8, a stirring rod 10 is inserted into the inner wall of the heating box 3, another pulley 6 is installed at the rear end of the stirring rod 10, a belt 7 is arranged on the outer side of the two pulleys 6, a motor 5 is installed on the rear side of the support frame 1, and the output end of the motor 5 is fixedly connected to the rear end of the left rotating shaft 8.

[0031] First, the worker pours the heated asphalt into the interior of the heating box 3, and starts the heating box 3 to assist in heating the asphalt to prevent the asphalt from solidifying. Then, the motor 5 is started to drive the left shaft 8 to rotate. Since the two shafts 8 are arranged on the inner side of the belt 7, the belt 7 is driven to convey. Since one of the pulleys 6 is installed at the rear end of the left shaft 8, and another pulley 6 is installed at the rear end of the stirring rod 10, the belt 7 is driven by the two pulleys 6 to transmit, and then the stirring rod 10 is driven to stir the asphalt inside the heating box 3 to improve the uniformity of the auxiliary heating, thereby preventing the asphalt from solidifying. Then, the asphalt is transported to the required place through the conveyor belt 4.

[0032] Embodiment 2

[0033] On the basis of Example 1, in order to facilitate the cleaning of the stirring rod 10, a top plate 9 is provided on the top of the heating box 3, two connecting blocks 13 are installed on the right side of the top plate 9, two supporting blocks 12 are installed on the right side of the heating box 3, and two locking buckles 11 are installed on the left side of the heating box 3; the supporting block 12 and the connecting block 13 are hinged, so as to facilitate workers to open the top plate 9.

[0034] When the surface of the stirring rod 10 needs to be cleaned after long-term use, the lock 11 is first opened. At this time, since two support blocks 12 are installed on the right side of the heating box 3, two connecting blocks 13 are installed on the right side of the top plate 9, and the connecting blocks 13 are hinged to the support blocks 12, the top plate 9 is opened through the handle set on the left side of the top plate 9, and then the worker cleans the stirring rod 10 inside the heating box 3. After cleaning, the top plate 9 is reset and the lock 11 is fastened to facilitate the worker to clean the stirring rod 10.

[0035] Embodiment 3

[0036] On the basis of the second embodiment, in order to facilitate the scraping of the residual asphalt on the surface of the conveyor belt 4, a collecting box 2 is installed at the bottom of the support frame 1, and a slide groove 16 is opened inside the collecting box 2. A limiting plate 17 is installed on the inner wall of the slide groove 16. A plurality of springs 18 are installed on one side of the limiting plate 17, and a scraper 15 is installed on the other side of the limiting plate 17. A collecting frame 14 is inserted in the middle of the collecting box 2.

[0037] When the conveyor belt 4 is conveying, since the top of the scraper 15 is in contact with the bottom of the conveyor belt 4, the elastic force of multiple springs 18 drives the limit plate 17 to move upward along the inner wall of the slide 16, thereby driving the scraper 15 to scrape the bottom of the conveyor belt 4, and then scraping the asphalt remaining on the surface of the conveyor belt 4 into the inside of the collection frame 14 to facilitate subsequent recycling.

[0039] On the basis of Example 3, in order to further improve the use effect of the scraper 15, the lower end of the spring 18 is installed on the bottom wall of the slide 16; the scraper 15 passes through the collecting box 2, and the top of the scraper 15 is in contact with the bottom of the conveyor belt 4 to facilitate scraping, thereby improving the service life of the conveyor belt 4.

[0040] The scraper 15 is driven by the elastic force of the spring 18 to scrape the surface of the conveyor belt 4, thereby preventing a lot of asphalt from accumulating on the surface of the conveyor belt 4, thereby increasing the service life of the conveyor belt 4 and facilitating the recovery of the asphalt.

[0041] In actual use, the worker first pours the heated asphalt into the interior of the heating box 3, and starts the heating box 3 to assist in heating the asphalt to prevent the asphalt from solidifying. Then the motor 5 is started to drive the left shaft 8 to rotate. Since the two shafts 8 are arranged on the inner side of the belt 7, the belt 7 is driven to transmit. Since one of the pulleys 6 is installed at the rear end of the left shaft 8, and another pulley 6 is installed at the rear end of the stirring rod 10, the belt 7 is driven by the two pulleys 6 to transmit, and then the stirring rod 10 is driven to stir the asphalt inside the heating box 3 to improve the uniformity of the auxiliary heating, thereby preventing the asphalt from solidifying. Then the asphalt is transported to the required place through the conveyor belt 4.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
