Both the pump 8 and the crack filling nozzle 10 are prior arts, and their functions are to fill the gaps above the road. The self-healing material is a special type of concrete. There is a relatively large amount of self-healing material inside the mixing kettle 5, and it is prevented from solidifying by stirring. During the crack filling process, it can enter the inside of the gap in a liquid state and solidify after the crack filling is completed, resulting in a better repair effect.

[0029] An air pump 11 is fixedly installed at the upper left of the top of the road crack filling trolley 1. A jet pipe 12 is fixedly installed on the left side of the air pump 11. A smoothing assembly is arranged above the road crack filling trolley 1, and a filling assembly is arranged above the mixing kettle 5; both the air pump 11 and the jet pipe 12 are prior arts, and can blow and clean the gaps above the road, making the device more flat during the crack filling process.

[0030] In this embodiment, the flattening assembly includes a first spring 13, a mounting frame 14, a rotating shaft 15, a movable shaft 16, a connecting flange 17, a flattening roller 18, a cleaning scraper 19 and a scraping mechanism. The first spring 13 is fixedly installed at the bottom of the road crack filling trolley 1. The mounting frame 14 is fixedly installed at the bottom of the first spring 13. The rotating shaft 15 is rotatably installed on the inner walls of the front and rear sides of the mounting frame 14. The movable shaft 16 is arranged below the mounting frame 14. The connecting flange 17 is fixedly installed on the outer sides of the rotating shaft 15 and the movable shaft 16. The flattening roller 18 is fixedly installed on the outer side of the movable shaft 16. The cleaning scraper 19 is fixedly installed on the inner wall of the top of the mounting frame 14.

[0031] In this embodiment, the filling assembly includes a motor 25, a driving shaft 26, a stirring rod 27, a cleaning plate 28 and a feeding spiral 29. The motor 25 is fixedly installed at the top of the mixing kettle 5. The driving shaft 26 is fixedly installed at the output end of the motor 25. The stirring rod 27 is fixedly installed around the outer side of the driving shaft 26. The cleaning plate 28 is fixedly installed on one side of the stirring rod 27. The feeding spiral 29 is fixedly installed on the outer side of the driving shaft 26.

[0032] In this embodiment, the scraping mechanism includes a second spring 20, a support frame 21, a self-healing material scraping plate 22, a fixing bolt 23 and a knob 24. The second spring 20 is fixedly installed on the right side at the bottom of the road crack filling trolley 1. The support frame 21 is fixedly installed at the bottom of the second spring 20. The self-healing material scraping plate 22 is arranged inside the support frame 21. The fixing bolt 23 is threadedly installed inside the self-healing material scraping plate 22. The knob 24 is fixedly installed on the outer side of one end of the fixing bolt 23.

[0033] In this embodiment, a feeding groove is formed at the top of the mixing kettle 5. The feeding device 6 is fixedly installed inside the feeding groove. The cleaning plate 28 is made of steel material and is in contact with the inner wall of the mixing kettle 5. In this embodiment, a sliding groove is formed on one side of the support frame 21. A T-shaped block is arranged at the rear side of the self-healing material scraping plate 22, and the T-shaped block is in contact with the sliding groove.

[0034] In this embodiment, two threaded holes are formed on one side of the support frame 21. The fixing bolt 23 is threadedly installed inside the threaded holes. An anti-slip pad is rotatably installed at one end of the fixing bolt 23. The self-healing material scraping plate 22 is in a C shape; so that the self-healing material scraping plate 22 can scrape up the excess self-healing material after moving, making the road surface relatively flat after filling.

[0035] In this embodiment, a heating electrode tube is arranged inside the heating sleeve 4. The bottom of the mixing kettle 5 is connected to the storage tank 7. A through groove is formed at the top of the storage tank 7; an electromagnetic valve is arranged outside the mixing kettle 5, so that the electromagnetic valve can control the mixing time of the raw materials inside the mixing kettle 5. The through groove facilitates the entry of the raw materials into the storage tank 7, so that the pump 8 can suck it.

[0036] Specifically, after the crack filling nozzle 10 sprays the self-healing material onto the inner side of the crack, the smoothing roller 18 at the rear can smooth it, enabling the smoothing roller 18 to cooperate with the first spring 13 above, making the smoothing roller 18 fit well with the road, resulting in a better smoothing effect. The self-healing material scraping plate 22 at the rear can scrape off the excess filling material and accumulate it in front of the self-healing material scraping plate 22, allowing the staff to reuse the excess self-healing material and making the road surface relatively flat. Moreover, the smoothing roller 18 and the self-healing material scraping plate 22 can be detachably maintained and replaced. The raw materials are added into the inner side of the mixing kettle 5 from the feeding device 6, and the motor 25 drives the drive shaft 26 and the stirring rod 27 to rotate, enabling the stirring rod 27 to stir and mix the raw materials. The cleaning plate 28 prevents the raw materials from adhering to the upper inner wall of the mixing kettle 5 during the feeding process, and the feeding screw 29 facilitates preventing the raw materials from clogging. The pump 8 can spray the raw materials in the storage tank 7 onto the inner side of the crack through the crack filling nozzle 10, and the heating sleeve 4 on the outside facilitates preventing the raw materials in the mixing kettle 5 from solidifying.

[0037] The above has introduced in detail a device for filling self-healing materials for road cracks provided by the present utility model. Specific embodiments are used herein to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
