The first driving component drives the cleaning brush to move to sweep the dust around the cracks. At the same time, the operator starts the vacuum cleaner, and the output end of the vacuum cleaner sucks the dust inside and around the cracks into the vacuum cleaner. The transfer pump starts to spray the crack repair agent at the cracks. The adjusting component controls the position of the nozzle to follow the cracks for spraying the crack repair agent, so that the crack repair agent completely covers the cracks. By setting the vacuum cleaner, the cleaning brush and the first driving component, the dust inside and around the cracks is cleaned to ensure the adhesion of the crack repair agent to the cracks.

[0055] The implementation principle of a building crack repair and filling device according to an embodiment of the present application is as follows:

[0056] When an operator repairs a wall crack, the operator covers the crack area with the covering cover 16, and the operator starts the first motor 24. The first motor 24 drives the second bevel gear 26 to rotate. The rotation of the second bevel gear 26 causes the first bevel gear 25 to rotate. The rotation of the first bevel gear 25 causes the first lead screw 21 to rotate. The rotation of the first lead screw 21 causes the cleaning brush 13 to move. The cleaning brush 13 moves and cleans the wall crack, and at the same time, the dust collector 14 removes the dust swept out by the cleaning brush 13.

[0057] After the cleaning brush 13 sweeps the wall dust, the data collector 41 collects the crack direction and width data. The processor processes the data collected by the data collector 41. The second motor 45 controls the output time of the second motor 45 and the telescopic distance of the cylinder 46 according to the data converted by the processor. When the second motor 45 is started, the second motor 45 drives the second lead screw 42 to rotate. The rotation of the second lead screw 42 causes the support seat 44 to move. The movement of the support seat 44 controls the horizontal output position of the nozzle 11. After the cylinder 46 is started, the cylinder 46 drives the third mounting seat 43 to move. The movement of the third mounting seat 43 causes the nozzle 11 to move. With the cooperation of the second motor 45 and the cylinder 46, the nozzle 11 sprays the repair agent along the crack track to the crack.

[0058] When the cleaning brush 13 moves to clean the dust around the crack, and after the nozzle 11 sprays the crack repair agent on the crack, the cleaning brush 13 then moves to the end of the first lead screw 21. The second trigger block 37 abuts against the trigger rod 35, causing the trigger rod 35 to rotate. The rotation of the trigger rod 35 causes the rotating column 33 to rotate, the rotation of the rotating column 33 causes the first spur gear 32 to rotate, the rotation of the first spur gear 32 causes the first rack 31 and the second rack 34 to move. The movement of the first rack 31 causes the second mounting seat 23 to move, the movement of the second mounting seat 23 causes the cleaning brush 13 to move away from the wall, and the movement of the second rack 34 causes the slide rod 151 to move. The movement of the slide rod 151 causes the scraper 15 to fit against the wall. When the first motor 24 rotates in reverse, the cleaning brush 13 moves towards the initial position. When the cleaning brush 13 moves to the initial position, the first trigger block 36 abuts against the trigger rod 35, causing the rotating column 33 to rotate in reverse. At this time, the first spur gear 32 rotates in reverse, and the cleaning brush 13 moves closer to the wall crack again, while the scraper 15 moves away from the wall crack. By providing the cleaning brush 13 and the vacuum cleaner 14, the dust around the crack is cleaned before repairing the crack, ensuring the adhesion of the crack repair agent to the crack.

[0059] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
