[0032] The first telescopic fixing component includes a first outer tube, a first inner tube and a first locking bolt. There are two first outer tubes, and both of the two first outer tubes are slidably connected to the first inner tube. The two ends of the first inner tube are respectively threadedly connected to the two first adjusting screws through connection blocks.

[0034] The second telescopic fixing component includes a second outer tube, a second inner tube and a second locking bolt. There are two second outer tubes, and both of the two second outer tubes are slidably connected to the second inner tube. The two ends of the second inner tube are respectively threadedly connected to the two second adjusting screws through connection blocks.

[0035] Specifically, handles are provided at the other ends of the first adjusting screw 5 and the second adjusting screw 6, so as to facilitate the user to rotate the first adjusting screw 5 and the second adjusting screw 6, so that the first telescopic fixing component and the second telescopic fixing component move along the first adjusting screw 5 and the second adjusting screw 6 respectively, realizing the extension of the first scraping plate 9 and the second scraping plate 10 from the top to the bottom of the main body bracket 1, so as to realize asphalt paving construction at different depths.
[0036] Specifically, both the first scraping plate 9 and the second scraping plate 10 can adopt the existing pull-out plate and pull-out laminate structures. By pulling the movable part of the first scraping plate 9, the adjustment of the first scraping plate 9 is realized. The same is true for the second scraping plate 10. The widths of the first scraping plate 9 and the second scraping plate 10 are 750 mm in the retracted state, and the widths of the first scraping plate 9 and the second scraping plate 10 are 1200 mm in the unfolded state, that is, the widths of the first scraping plate 9 and the second scraping plate 10 are 750 - 1200 mm.

The limiting component 2 includes a movable sleeve and a pin. The movable sleeve is fixed on the inner side of the main body bracket 1. The pin is movably connected to the movable sleeve. By adjusting the pin to extend from the movable sleeve to the asphalt ground to be paved, the pin naturally adheres to the edge of the side curb on the side to be constructed after the width is adjusted. Under the combined action of the 4 pins, the advancing direction of the asphalt paving device is fixed between the two side curbs, so that during the process of paving asphalt by the asphalt paving device, the pin can make the asphalt paving device advance forward along the side curb.

[0041] The process of using the asphalt paving device for paving:
[0042] 1. The asphalt paving device is in place. According to the paving width, adjust the paving widths of the first scraper 9 and the second scraper 10. Loosen the locking bolt 13 of the telescopic fixing component, pull the first scraper 9 and the second scraper 10 out from the middle to both sides to elongate, adjust the width, and tighten the locking bolt 13 to fix the paving width to meet the working surface requirements (the adjustment range is 750 - 1200 mm);
[0043] 2. Adjust the paving thickness. According to the construction site, adjust the height of the first scraper 9 and the second scraper 10 through the first adjusting screw 5 and the second adjusting screw 6 to meet the construction requirements. The height of the first scraper 9 is slightly higher than the second scraper 10. The first scraper 9 is used to initially flatten the mixture, and then the second scraper 10 is used to control the paving thickness.
[0044] 3. Adjust the limit assembly 2, unscrew the pin, and ensure that the asphalt paving device moves forward along the side flat stone;
[0045] 4. Spray an appropriate amount of isolation agent on the first scraper 9 and the second scraper 10. After laying the material, manually pull and push the traction rod 8 to make the asphalt paving device pave forward. The pulley moves along the side flat stone or the finished surface to reduce the disturbance of the mixture, reduce segregation, speed up the construction progress, reduce temperature loss, and ensure the paving quality.
[0046] Compared with the manual paving method, the asphalt paving device provided in this embodiment is easy to transport and load, can meet the working range of 750-1200mm non-motorized vehicle lanes, and adopts a double scraper independent height control design to achieve the effect of rough leveling of the front scraper and fine leveling of the rear scraper after the mixture is spread, reduce the segregation of the mixture, improve the flatness and surface quality of the paving surface, and add a limit device to ensure that the asphalt paving device is advanced along the side flat stone. In addition, it can effectively increase the paving speed, reduce temperature loss, ensure the subsequent rolling temperature, and improve the overall quality and efficiency of asphalt paving on non-motorized vehicle lanes.
