Rotating the adjusting screw rod 305 can lift and lower through the threaded cooperation with the installation plate 300, so that the adjusting screw rod 305 drives the scraping plate 302 to descend through the fixing strip one 304, making the scraping plate 302 close to the ground. Under the movement of the support frame 100, the scraping plate 302 can be driven to scrape the smeared asphalt flat.

[0029] Embodiment 2: As Figures 1-5 , the pressing structure includes a fixing strip two 401. The fixing strip two 401 is installed on one side of the scraping plate 302. The fixing strip two 401 is slidably installed on the limiting sliding rod 400. One end of the limiting sliding rod 400 is installed with a pressing plate 402. An extrusion disc 403 is sleeved on the limiting sliding rod 400. One end of a spring 404 is installed on the extrusion disc 403. The other end of the spring 404 is installed on the fixing strip one 304. The spring 404 is slidably sleeved on the limiting sliding rod 400. A sliding hole 405 is opened on the inner wall of the fixing strip one 304. The limiting sliding rod 400 is slidably installed in the sliding hole 405. During the continuous descent of the scraping plate 302, the fixing strip one 304 will slide on the limiting sliding rod 400 through the sliding hole 405. At the same time, the fixing strip one 304 will cooperate with the extrusion disc 403 to compress the spring 404. Under the extrusion of the spring 404, the pressing plate 402 can be made to closely adhere to the ground. Under the continuous movement of the support frame 100, the pressing plate 402 can be pressed on the filled asphalt under the action of the spring 404 to flatten the asphalt. The remaining features are the same as those in Embodiment 1.

[0030] The working principle is as follows: When in use, the asphalt nozzle 203 can be aligned with the gap on the road surface. By pushing the push rod 206, the support frame 100 and the universal wheels 101 are driven to move, so that the support frame 100 drives the asphalt silo 102 to move, and then the asphalt nozzle 203 can be driven to move above the gap. At the same time, the adjusting screw rod 305 can be rotated. The rotating adjusting screw rod 305 will rotate on the limiting rotating shaft 311. During the rotation of the adjusting screw rod 305, it can be lifted and lowered through the thread fit with the mounting plate 300, so that the adjusting screw rod 305 drives the scraping plate 302 to descend through the first fixing strip 304, making the scraping plate 302 close to the ground. At the same time, the descending scraping plate 302 will drive the second fixing strip 401 to descend, so that the second fixing strip 401 drives the limiting slide rod 400 and the pressing plate 402 to descend, and finally the pressing plate 402 can be in contact with the ground. During the continuous descent of the scraping plate 302, the first fixing strip 304 will slide on the limiting slide rod 400 through the sliding hole 405, and at the same time, the first fixing strip 304 will cooperate with the extrusion disc 403 to compress the spring 404. Under the extrusion of the spring 404, the pressing plate 402 can be tightly attached to the ground. During the caulking process, the asphalt pump 200 and the blower 204 can be turned on. The blower 204 can blow air into the gap through the air duct 205 to blow out the dust in the gap, while the asphalt pump 200 can pump out the asphalt in the asphalt silo 102, then transport it through the delivery pipe 201, and finally spray it into the gap through the asphalt nozzle 203 to fill it. Under the movement of the support frame 100, the scraping plate 302 can be driven to scrape the applied asphalt flat. The scraping side plates 303 arranged on both sides of the scraping plate 302 can prevent the asphalt from leaking out from both sides. And by rotating the knob 310, the limiting screw rod 309 can be driven to rotate. When the limiting screw rod 309 rotates, it can vertically move through the thread fit with the threaded sliding seat 306. The moving threaded sliding seat 306 can drive one end of the connecting rod 307 to rotate and move, and the other end of the connecting rod 307 will rotate on the connecting piece 308 and at the same time push the connecting piece 308 to move, so that the connecting piece 308 drives the scraping side plate 303 to move, thereby being able to adjust the scraping range of the scraping side plates 303 on both sides to adjust according to the size of the gap to be filled. Under the continuous movement of the support frame 100, the pressing plate 402 can be pressed on the filled asphalt under the action of the spring 404 to flatten the asphalt and complete the caulking operation.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
