[0032] The utility model is further described below in conjunction with the accompanying drawings:

[0033] like Figure 1-Figure 11 As shown, a road surface disease repair device includes a lifting truss 4, two symmetrical adjustment hydraulic rods 5 are fixed at both ends of the lifting truss 4, and support portals 6 for installing the adjustment hydraulic rods 5 are provided at both ends of the lifting truss 4. Universal wheels for moving the entire device are fixed at the lower end of the support portal 6, and also include a repair mechanism 1 and a scraping mechanism 2;

[0034] In this embodiment: the repair mechanism 1 includes a mixing drum 11, the lower end of the mixing drum 11 is connected to a road surface dispersing cover 12, the road surface dispersing cover 12 is rotatably connected to a swing frame 15, and the two ends of the swing frame 15 extending out of the road surface dispersing cover 12 are fixed with swing levers 16, and the bottom of the lifting truss 4 is fixed with a lower tooth bar 17 and an upper tooth bar 18 for allowing the two swing levers 16 to swing alternately, and the upper tooth bar 18 is located in front of the lower tooth bar 17. The front and rear sides of the mixing drum 11 are both provided with a moving mechanism 3 that moves on the lifting truss 4. A broadcasting wheel 14 for quantitatively delivering the repair material is provided inside the mixing drum 11, and the mixing drum 11 is rotatably connected to the broadcasting wheel 14, and a plurality of grooves are distributed in an annular manner on the outer side of the broadcasting wheel 14. The broadcasting wheel 14 outputs A driving motor 13 is fixedly provided at the inlet end to drive it to rotate. The swing frame 15 is located inside the road surface dispersing cover 12 and has two side plates fixed thereon, and the two side plates are distributed in an inverted V-shaped structure. The rotating part of the driving motor 13 drives the broadcasting wheel 14 to rotate inside the mixing drum 11, so as to quantitatively introduce the repair material in the mixing drum 11 into the road surface dispersing cover 12. Subsequently, the mixing drum 11 is driven by the moving mechanism 3 to move on both sides along the lifting truss 4. The movement of the mixing drum 11 allows the swing levers 16 on the front and rear sides of the swing frame 15 to swing alternately along the upper tooth bar 18 and the lower tooth bar 17 respectively, and then the swing frame 15 is alternately swung inside the road surface dispersing cover 12 to evenly spread the repair material onto the road surface.

[0035] In this embodiment, the scraping mechanism 2 includes a scraping plate 24, the upper end of the scraping plate 24 is fixed to one side of the mixing drum 11, a limiting frame 25 is fixed to the top of the scraping plate 24, a knocking hammer 23 is provided between the scraping plate 24 and the limiting frame 25, and a connecting rod 22 is provided on the side of the knocking hammer 23 close to the mixing drum 11, a slide groove for sliding the knocking hammer 23 is opened on the connecting rod 22, and a connecting column for moving in the slide groove is fixed to the rear side of the knocking hammer 23, and a crank 21 is rotatably connected to the upper end of the connecting rod 22, and one end of the broadcast wheel 14 extending out of the mixing drum 11 is fixedly connected to the crank 21, and the crank 21 is located at the mixing drum 11. On one side, the scraping plate 24 is made of an L-shaped steel plate. The movement of the mixing drum 11 is used to move the scraping plate 24 on the spilled repair material, thereby scraping away the excess repair material. At the same time, the rotation of the broadcasting wheel 14 is used to drive the crank 21 to rotate. The rotation of the crank 21 drives the hammer 23 to be lifted upward along the limit frame 25 through the connecting rod 22 and the connecting column. As the crank 21 rotates, when the connecting rod 22 moves downward, the limit frame 25 will fall into the sliding groove of the connecting rod 22 and hit the scraping plate 24, thereby compacting the repair material on the lower side of the scraping plate 24.

[0036] In this embodiment: the moving mechanism 3 includes two moving frames 31, and the two moving frames 31 are respectively fixed on the front and rear sides of the mixing drum 11. The two moving frames 31 are rotatably connected to the sides close to the mixing drum 11 with two auxiliary wheels 33 and a single driving wheel 34. The two auxiliary wheels 33 are respectively located on both sides of the driving wheel 34. A moving motor 32 for driving the driving wheel 34 to rotate is fixed on the moving frame 31. Guide grooves for the auxiliary wheels 33 and the driving wheel 34 to roll are provided on the front and rear sides of the lifting truss 4. The driving wheel 34 is driven to rotate by the rotating part of the moving motor 32. The rotation of the driving wheel 34 drives the entire mixing drum 11 to move along the lifting truss 4, and the auxiliary wheels 33 are used to provide auxiliary support for the mixing drum 11 during the movement.

[0037] Working principle: When in use, push the support gantry 6 to drive the entire device to cross the road surface defect position that needs to be repaired, and then use the rotating part of the mobile motor 32 on the mobile frame 31 to drive the driving wheel 34 to rotate, and the rotation of the driving wheels 34 on the two mobile frames 31 drives the entire mixing drum 11 to move along the lifting truss 4 to the side of the road surface defect position. In this process, the four auxiliary wheels 33 on the two mobile frames 31 are used to assist the movement of the mixing drum 11, and at the same time, the four adjustment hydraulic rods 5 telescopic parts are used to push the lifting truss 4 to move downward, so that the bottom of the scraper plate 24 is attached to the normal road surface;

[0038] At this time, the stirred road repair material is poured into the mixing drum 11, and then the broadcast wheel 14 is driven to rotate by the rotating part of the driving motor 13, and the road repair material is quantitatively introduced into the road dispersing cover 12 through the groove on the broadcast wheel 14. At the same time, the mixing drum 11 is driven to move along the lifting truss 4 to the other side of the road disease position under the action of the moving mechanism 3. At this time, the swing levers 16 at the front and rear ends of the road dispersing cover 12 will pass through the upper tooth bar 18 and the lower tooth bar 17 respectively;

[0039] The sliding process of the two swing levers 16 between the lower tooth bar 17 and the upper tooth bar 18 is as follows:

[0040] like Fig.10 As shown, when the swing lever 16 on the front side of the swing frame 15 contacts the teeth on the upper tooth bar 18, the swing lever 16 on the front side of the swing frame 15 drives the swing frame 15 to flip forward at a certain angle inside the road dispersion cover 12, and the swing lever 16 on the rear side of the swing frame 15 is located between the two teeth of the lower tooth bar 17;

[0041] like Fig.11As shown, when the swing lever 16 on the front side of the swing frame 15 passes through the teeth on the upper tooth bar 18, the swing lever 16 on the front side of the swing frame 15 is located between the two teeth of the upper tooth bar 18, and the swing lever 16 on the rear side of the swing frame 15 contacts the teeth of the lower tooth bar 17. At this time, as the mixing drum 11 continues to move, the swing lever 16 on the rear end of the swing frame 15 passes through the contacting teeth, and then the swing frame 15 is reversed at a certain angle inside the road surface dispersion cover 12;

[0042] Repeat the above operation, when the swing frame 15 in the road spreading cover 12 swings forward and backward alternately, the road repair material will be evenly scattered to the road disease position, and then the scraping plate 24 will be scraped from the scattered road repair material under the movement of the mixing drum 11, and the excess road repair material will be scraped away, and the bottom of the scraping plate 24 will be pressed on the road disease position where the repair material is scattered, and the crank 21 will be driven to rotate as the broadcast wheel 14 rotates;

[0043] When the crank 21 rotates, the connecting rod 22 and the striking hammer 23 are firstly driven to be lifted upward, and the striking hammer 23 will move vertically upward along the limiting frame 25;

[0044] Then, as the crank 21 rotates, when the upper end of the connecting rod 22 passes the highest point of the crank 21, the connecting rod 22 moves downward, and the connecting rod 22 no longer pulls the hammer 23 upward. At this time, the hammer 23 falls downward along the slide groove of the scraping plate 24 under the action of the connecting column. At this time, the falling hammer 23 hammers the scraping plate 24. The above operation is repeated to continuously hammer the scraping plate 24 and the road repair material under it, so as to compact the repair material at the road disease position;

[0045] When the mixing drum 11 moves to the other side of the lifting truss 4, the repair mechanism 1 and the scraping mechanism 2 are moved back to one side of the lifting truss 4 through the moving mechanism 3, and the position of the supporting gantry 6 is adjusted to repeat the above operation until the road surface disease position is completely repaired.

[0046] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
