However, this patent still has the following problems in actual use:

[0004] The aforementioned devices cannot automatically clean the dust in the gaps before use, and manual cleaning is still required, which is quite troublesome. Existing simple vacuuming devices cannot suck up larger stones. These stones get stuck in the gaps and need to be manually removed, which increases the intensity of manual cleaning and is not conducive to use.

[0005] An asphalt repair device for highway pavement maintenance is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide an asphalt repair device for highway pavement maintenance, in order to solve the problems mentioned in the background art. The aforementioned devices cannot automatically clean the dust in the gaps before use, and still require manual cleaning in advance, which is quite troublesome. Existing simple dust suction devices cannot suck up large gravel. Such gravel gets stuck in the gaps and needs to be manually removed, which increases the paving intensity of manual cleaning and is not conducive to use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an asphalt repair device for highway pavement maintenance, comprising a pushcart board and a pushcart railing installed on the right side of the top surface of the pushcart board, wherein a joint filling device is fixedly installed in the middle of the pushcart board;

[0008] A dust removal component is provided on the left side of the grouting device, and an application component is provided on the right side of the grouting device;

[0009] The dust removal assembly includes a dust removal box fixedly installed on the top surface of the trolley board, and a dust collector and a dust collection pipe are fixedly installed on the outside of the dust removal box.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: This asphalt repair device for highway pavement maintenance sweeps and pushes dust in the gaps to the center through the first and second sweeping shafts, where it is then extracted by the dust extraction pipe. When larger stones accumulate and exceed the gaps, a deflector pushes the stones to both sides of the gaps, thus preventing the stones from affecting dust extraction and gap repair. It also eliminates the need for manual dust removal and stone cleaning, saving time and labor. The specific details are as follows:

[0019] 1. The first rotating wheel, the first belt, and the second rotating wheel cause the second sweeping shaft and the second rotating wheel to rotate clockwise, which in turn causes the second gear to drive the central rotating column to rotate counterclockwise. At this time, the fourth rotating wheel, the second belt, and the fifth rotating wheel cause the first sweeping shaft to rotate counterclockwise, while the third rotating wheel, the third belt, and the sixth rotating wheel drive the reciprocating screw to rotate. Finally, the threaded sleeve drives the bent connecting rod to move back and forth, so that the brushes on the outside of the first and second sweeping shafts sweep and push the dust in the gaps to the middle, where it is then extracted by the dust extraction pipe. When larger stones are pushed out of the gaps, the moving paddle pushes them to the sides of the gaps, thus preventing the stones from affecting dust extraction and gap repair. This eliminates the need for manual dust cleaning and stone removal, saving time and effort. Attached Figure Description

The first sweeping shaft 207 and the second sweeping shaft 208 are both fixed with brushes. When there are few stones in the gap, they will be pushed and moved with the movement of the trolley plate 1. When there are many stones, the stones will be piled up above the gap. The higher part will be pushed to both sides of the gap by the pusher block 225 to avoid too many stones affecting the filling of the gap.

[0034] Among them, the outer side of the extension cover 204 is fixedly connected to the linkage cover 205, and the side of the dust collection box 201 is fixedly installed with the first motor 206.

[0035] A threaded sleeve 222 is threadedly connected to the reciprocating lead screw 226. The threaded sleeve 222 is fixedly connected to the bending connecting rod 223. A telescopic protective cover 224 is fitted over the reciprocating lead screw 226. Both ends of the telescopic protective cover 224 are fixedly connected to the mounting chamber 209. The bending connecting rod 223 passes through the telescopic protective cover 224 and is fixedly connected to the telescopic protective cover 224. The telescopic protective cover 224 can prevent dust from contaminating the reciprocating lead screw 226.

[0036] One end of the first sweeping shaft 207 extends into the extension cover 204 and is fixedly connected to the fifth rotating wheel 219. The end of the second sweeping shaft 208 extends into the extension cover 204 and is fixedly connected to the first gear 212 and the second rotating wheel 213. The extension cover 204 is rotatably connected to the central rotating column 214. The central rotating column 214 is fixedly connected to the second gear 215, the third rotating wheel 216 and the fourth rotating wheel 217.

A groove is provided on the lifting column 303, and the groove is slidably connected to the protruding plate 301.

[0040] The bottom end of the lifting column 303 is fixedly connected to a V-shaped trowel 304; when in use, the V-shaped trowel 304 is in contact with the ground and applies asphalt.

[0041] Working principle: Before using this type of asphalt repair device for highway pavement maintenance, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 8 As shown, the first motor 206 is started first. The first rotating wheel 210, the first belt 211 and the second rotating wheel 213 cause the second sweeping shaft 208 and the second rotating wheel 213 to rotate clockwise, which causes the second gear 215 to drive the central rotating column 214 to rotate counterclockwise. At this time, the first sweeping shaft 207 is rotated counterclockwise through the fourth rotating wheel 217, the second belt 218 and the fifth rotating wheel 219. The third rotating wheel 216, the third belt 221 and the sixth rotating wheel 220 drive the reciprocating screw 226 to rotate. Finally, the threaded sleeve 222 drives the bent connecting rod 223 to move back and forth. Finally, the brushes on the outside of the first sweeping shaft 207 and the second sweeping shaft 208 sweep the dust in the gap and push it to the middle, where it is then sucked away by the dust extraction pipe 203. When larger stones are pushed higher than the gap, the movable paddle 225 pushes them to the sides of the gap, thus preventing the stones from affecting the dust extraction and gap repair. This avoids manual dust cleaning and stone removal, saving time and effort.

[0042] After the asphalt is filled, the V-shaped trowel 304 will assist in the leveling of the asphalt. Then, by rotating the nut 302, the lifting column 303 will rise, thereby causing the V-shaped trowel 304 to move upward, making it easier to clean the V-shaped trowel 304.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
