A mixing shaft is arranged inside the asphalt mixing tank 10, and the mixing power chassis 5 is connected to the mixing shaft through a transmission belt. A head 1 is arranged on the left end of the frame 3, and mobile wheels 2 are arranged on the front and rear ends of the head 1 and the frame 3. A fuel tank 4 is provided at the bottom of the left end of the frame 3. When the mobile low-carbon asphalt mixing station is used, the driver first needs to drive the mobile low-carbon asphalt mixing station to the section where the road needs to be paved, then stabilize the mobile low-carbon asphalt mixing station, and put the asphalt into the asphalt heating box 7. The asphalt heating box 7 will heat the asphalt to the optimal temperature, and transport the heated asphalt to the asphalt mixing tank 10 through the asphalt conveying pipe 8. At the same time, gravel will be put into the asphalt mixing tank 10 through the gravel feeding hopper 9. The stirring power chassis 5 drives the stirring shaft inside the asphalt mixing tank 10, and the stirring shaft will stir the asphalt and gravel inside the asphalt mixing tank 10 through the stirring roller, so that the heated asphalt and gravel are fully mixed. Finally, the mixed gravel and asphalt mixture will be discharged through the discharge port 12, and the discharged asphalt and gravel mixture will be used for paving.

[0021] like Figure 1 and Figure 3 As shown, an anti-cooling device 11 is arranged outside the middle section of the asphalt mixing tank 10, and the anti-cooling device 11 includes a support frame 13, a top plate 14, a gas storage tank 17 and a gas filling valve 19. The support frame 13 is provided with two groups, and the two groups of support frames 13 are respectively located outside the front and rear ends of the asphalt mixing tank 10. The bottom ends of the two groups of support frames 13 are fixedly connected to the frame 3 by bolts, and the top ends of the two groups of support frames 13 are connected to the top plates 14, and the top ends of the top plates 14 are fixed with the gas storage tank 17 by a fixing sleeve. A gas filling valve 19 is provided at the right end of the gas tank 17, and the anti-cooling device 11 also includes a gas collecting pipe 15, a stop valve 16, an igniter 18 and a flame head 20.
