[0002] Asphalt is a dark brown complex mixture of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid, mostly existing in liquid or semi-solid petroleum form. The surface is black and needs to be spread before asphalt can be used.

[0003] For example, in an asphalt paving device with the authorization announcement number "CN219604103U", the fixed knob is threadedly rotated on the outside of the threaded rod, and the scraper can be lifted and lowered through the threaded rod, so that the device can be adjusted according to the thickness of the asphalt to be laid. However, when adjusting the scraper of the asphalt paving device, workers need to manually turn the two threaded rods at the same time to adjust the scraper, and the manual adjustment has a certain deviation, resulting in the quality of asphalt paving not meeting expectations, thereby reducing the work quality. At the same time, when the asphalt paving device is paving asphalt, wheel pits will be left where the wheels pass, resulting in the need to pave the asphalt at the wheel pits again, thereby reducing work efficiency.

[0028] Working principle:

[0029] Asphalt paving process:

[0030] When asphalt paving is required, the worker turns the first handle 202, the first handle 202 drives the worm 203 to rotate, the worm 203 drives the worm wheel 204 to rotate, and the cross bar 205 of the worm wheel 204 swings clockwise (such as Figure 4 ), the pin of the cross bar 205 drives the block 206 to move downward, the block 206 drives the cross plate 207 to move in the first shell 8 through the slide groove, the cross plate 207 drives the vertical plate 201 to move, the vertical plate 201 drives the second plate 7 to move, and when the second plate 7 is adjusted to the position required for paving asphalt, the first handle 202 is stopped from rotating. According to the above method, the first handle 202 can be reversed to drive the second plate 7 to reset, and the position of the second plate 7 is adjusted in the above method;

[0031] Then, the second handle 302 is rotated, and the second handle 302 drives the threaded rod 303 to rotate, and the threaded rod 303 drives the nut 304 to move leftward (such as Figure 6 ), the nut 304 drives the connecting rod 305 to move through the pin shaft, and the right end of the inclined plate 306 is slidably connected to the second shell 301 through the pin shaft. Therefore, when the connecting rod 305 moves to the left, the connecting rod 305 drives the inclined plate 306 to swing counterclockwise through the pin shaft. When the surface of the inclined plate 306 reaches the position required for paving asphalt, the second handle 302 is stopped from rotating, and the bolts on the second handle 302 are screwed to make it press against the second shell 301, thereby strengthening the fixation of the inclined plate 306. According to the above method, the second handle 302 can be reversed to drive the inclined plate 306 to reset. In the above method, the inclined plate 306 behind the wheel 6 is dropped to pave the asphalt at the wheel pit;

[0032] Finally, the worker pulls the handrail 4 to drive the frame 1 to move. During the movement, the surface of the second plate 7 of the frame 1 contacts the asphalt so as to spread it (the principle of the inclined plate 306 is the same as that of the second plate 7). The two first plates 5 can prevent the asphalt from overflowing to both sides and affecting the rotation of the wheels 6 when paving the asphalt.

[0033] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
