On the other side of the outer housing 1, a machine base 5 is fixedly installed. On one side of the machine base 5, a motor 6 is fixedly installed. The motor 6 is electrically connected to an external main controller through a connecting wire. A second shaft seat 7 is movably installed on the outer housing 1 near one side of the machine base 5. A rotating shaft 8 is movably installed between the two second shaft seats 7. A plurality of mounting seats 9 are fixedly installed on the outer side of the rotating shaft 8. And two support plates 10 are respectively fixedly installed on two of the mounting seats 9. And a lead screw 19 is movably installed between two of the support plates 10 and the second shaft seat 7.

[0029] On one side inside the outer casing 1, two flame guiding covers 12 are fixedly installed, and the flame guiding covers 12 communicate with the output cavities of the corresponding burners 2. An exhaust pipe 13 is fixedly installed on the top of the outer casing 1. A collar 21 is also provided on the machine base 5 on one side of the motor 6. A toothed groove 22 is formed inside the collar 21. A base 23 is fixedly installed at the bottom of the collar 21, and the base 23 is fixedly installed on the machine base 5. By means of the setting of the collar 21, it can provide the basic conditions for the rotating shaft 8 to drive the two lead screws 19 to rotate synchronously. The second shaft seat 7 is rotatably installed on one side of the outer casing 1 and the mixing drum 14 through a shaft seal. By means of the setting of the second shaft seat 7, while ensuring the normal rotation of the mounting seat 9 and the lead screw 19, the sealing performance of the mixing drum 14 can be ensured. One side of the rotating shaft 8 passes through the shaft seal at the central position inside the second shaft seat 7 and extends to one side of the outer casing 1 and is fixedly connected to the output end of the motor 6. A driving gear 17 is fixedly installed on the rotating shaft 8 located inside the collar 21. A mixing paddle 16 is fixedly installed on one side of the support plate 10.

[0030] Embodiment 2:

[0031] Refer to Figures 3 - 4 For the second embodiment of the present utility model, the difference between this embodiment and the first embodiment is that two connecting rods 15 are fixedly installed inside the inner side of the scraping ring 11. The scraping ring 11 is inserted and installed inside the mixing drum 14, and the side of the connecting rod 15 away from the scraping ring 11 is threadedly connected to the corresponding lead screw 19. Through the setting of the driving gear 17, the driven gear 20 and the two mounting seats 9, while the rotating shaft 8 drives the two lead screws 19 to revolve around the rotating shaft 8 as the axis, the two lead screws 19 can rotate self - sufficiently, thereby driving the scraping ring 11 to move inside the mixing drum 14.

[0032] It should be noted that the present utility model is an asphalt mixing device. When mixing asphalt and filler, the top cover of the outer casing 1 can be opened, and then the asphalt and filler are poured into the mixing drum 14 in sequence. Then, the top cover is closed, and the burner 2 and the motor 6 are respectively started by an external main controller. Thus, the burner 2 heats the mixing drum 14 from inside the outer casing 1. At the same time, the output end of the motor 6 drives the rotating shaft 8 to rotate, so that the rotating shaft 8 rotates between the first shaft seat 4 and the second shaft seat 7. At the same time, the rotating shaft 8 drives multiple groups of support plates 10 and mixing blades 16 on the outside to rotate in the mixing drum 14, thereby mixing and stirring the asphalt and filler in the mixing drum 14. At the same time, the two support plates 10 on the outside of the two mounting seats 9 respectively drive the corresponding lead screws 19 to rotate synchronously, so that the two lead screws 19 rotate in the shaft seals in the second shaft seat 7 and drive the second shaft seat 7 to rotate on one side of the outer casing 1 and the mixing drum 14. At the same time, the driving gears 17 on the outside of the rotating shaft 8 are respectively meshed and connected with the two driven gears 20, and the two driven gears 20 are in turn meshed and connected with the tooth grooves 22 in the collar 21, so that the mixing blades 16 and the lead screws 19 and the scraping ring 11 revolve around the rotating shaft 8 as the axis in the mixing drum 14. At the same time, the two driven gears 20 respectively drive the lead screws 19 to rotate self - rotatably in the second shaft seat 7 and the corresponding supporting seats 18, so that the two lead screws 19 also respectively rotate in the screw holes on one side of the corresponding connecting rods 15, so that the scraping ring 11 moves horizontally in the mixing drum 14 while rotating around the rotating shaft 8 as the axis, thereby cooperating with the mixing blades 16 to make the asphalt and filler in the mixing drum 14 mix more evenly, and preventing part of the asphalt from continuously depositing at the bottom of the mixing drum 14. And by controlling the forward and reverse rotation of the motor 6, the reciprocating motion of the scraping ring 11 can be realized. When discharging, the asphalt remaining on the inner wall of the mixing drum 14 can be scraped towards the discharge door 3. At the same time, with the graphite coating applied on the outer surfaces of the rotating shaft 8, the mounting seats 9, the support plates 10, the scraping ring 11, the connecting rods 15, and the mixing blades 16, the adhesion of asphalt to them can be prevented.
