However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Embodiment 1

[0025] See also Figure 1-6The utility model provides a technical solution: a construction mechanism for cold patching asphalt mixture of urban asphalt pavement, comprising a fixed frame 1, the bottom surface of which is installed with pulleys 14, which are evenly distributed at the four corners of the bottom surface of the fixed frame 1, so as to facilitate the movement and positioning of the equipment. A mounting plate 2 is fixedly installed on the inner side of the fixed frame 1 by welding, and an asphalt storage tank 3 is fixedly installed on the top surface of the mounting plate 2 by bolt connection, which is used to store asphalt cold patch material. A motor 4 is fixedly installed on the top of the asphalt storage tank 3 by bolts, and a stirring blade 5 is installed at the output end of the motor 4, which is used to stir and mix the asphalt cold patch material in the asphalt storage tank 3 to ensure its uniformity. A feed hopper 6 is connected to the surface of the asphalt storage tank 3, which is convenient for adding asphalt cold patch material into the asphalt storage tank 3. A distribution plate 7 is connected to the bottom end of the asphalt storage tank 3, and a valve 13 is arranged on the surface of the distribution plate 7. By controlling the switch of the valve 13, the outflow of the asphalt cold patch material can be conveniently controlled.

[0026] See also Figure 1-6 , a horizontal plate 8 is also fixedly installed on the inner side of the fixing frame 1, and a threaded rod 9 and a vertical rod 10 are provided through the top surface of the horizontal plate 8. A thread is provided inside the horizontal plate 8, and the thread is engaged with the threaded rod 9, so that the threaded rod 9 can move up and down in the horizontal plate 8. The bottom end of the threaded rod 9 is rotatably connected to the bottom plate 11 through a bearing, and the vertical rod 10 is slidably connected to the horizontal plate 8. At the same time, the vertical rod 10 is fixedly connected to the bottom plate 11 to ensure the stability of the bottom plate 11. A scraper 12 is fixedly installed on the bottom surface of the bottom plate 11 by bolts. The material of the scraper 12 is selected from high-strength wear-resistant steel to ensure its service life and scraping effect. Embodiment 2

[0027] See also Figure 4-5 , a trimming mechanism is provided on the surface of the fixing frame 1, and the trimming mechanism includes a slot 15, which is provided on the surface of the fixing frame 1, and a plug 16 is slidably connected to the inner wall of the slot 15. This design allows the plug 16 to slide up and down inside the slot 15, thereby adjusting the position of the cutter 19. In order to achieve stable sliding and precise positioning, the inner wall of the slot 15 is also provided with positioning holes 17 arranged at equal distances. The plug 16 is a key component that cooperates with the slot 15, and a positioning bolt 18 is inserted on its surface. The positioning bolt 18 is adapted to the size of the positioning hole 17. When the positioning bolt 18 is tightened and inserted into the corresponding positioning hole 17, the plug 16 is firmly fixed at a certain position in the slot 15. A cutter 19 is fixedly installed on the bottom surface of the plug 16. The function of this cutter 19 is to cut off the excess asphalt cold patch material on the edge of the road surface to ensure that the edge of the road surface after construction is neat and tidy and prevent the asphalt cold patch material from overflowing.

[0028] Working principle: the asphalt cold patch material enters through the feed hopper 6, and then the motor 4 can drive the stirring blade 5 to rotate, so as to stir and mix the asphalt cold patch material. When paving, you only need to open the valve 13, and then the asphalt cold patch material can slide out from the cloth plate 7, and then push the utility model to pave asphalt. At the same time, through the provided scraper 12, when filling the gaps in the road surface, the staff can twist the threaded rod 9. At this time, since the cross plate 8 is provided with threads, the threaded rod 9 can move in the cross plate 8 at this time, and the threaded rod 9 then drives the bottom plate 11 and the scraper 12 to move until the scraper 12 is close to the road surface. In this way, after the asphalt cold patch material enters the gaps in the road surface, The scraper 12 can be used to scrape off the raised asphalt cold patch material, thereby ensuring the flatness of the road surface. The scraper 12 provided in the utility model can be easily adjusted in position. The staff only needs to twist the threaded rod 9 to accurately control the distance between the scraper 12 and the road surface, which is very useful for scraping off excess asphalt cold patch material when filling road gaps. The scraper 12 is used to scrape off the raised asphalt cold patch material, thereby ensuring the flatness of the road surface and improving the construction quality. At the same time, it also helps to improve the safety and comfort of road use, and is particularly suitable for the rapid cold patch construction of urban asphalt pavements, and is particularly suitable for small-area, immediate road repair work, and can respond quickly and In order to deal with the problem of road damage, the cutter 19 is provided to cut off the excess asphalt cold patch material on the edge of the road surface, so as to prevent the asphalt cold patch material from overflowing the edge of the road surface. At the same time, the cutting depth of the cutter 19 can be adjusted according to the actual situation. The staff only needs to screw out the positioning bolt 18. After the positioning bolt 18 leaves the positioning hole 17, the plug block 16 is released from the limit, and the plug block 16 can slide in the slot 15. At this time, the upper and lower positions of the plug block 16 can be adjusted to adjust the cutting depth of the cutter 19, and then the positioning bolt 18 is screwed in until the positioning bolt 18 is inserted into the positioning hole 17. The knife 19 can accurately cut off the excess asphalt cold patch material at the edge of the road surface, thereby keeping the edge of the road surface clean and tidy, avoiding the unsightly and safety hazards caused by the asphalt cold patch material overflowing from the edge of the road surface. At the same time, the cutting depth of the cutter 19 can be adjusted according to actual conditions, so that construction personnel can accurately control the cutting depth of the cutter 19 according to different road conditions and construction requirements, so as to achieve the best construction effect, and the method of adjusting the depth of the cutter 19 is simple and easy. The staff only needs to unscrew the positioning bolt 18, adjust the position of the insert block 16, and then screw in the positioning bolt 18. This process does not require complicated tools or techniques, which improves the convenience of construction.
