[0033] The rolling mechanism 7 is arranged inside the second assembly groove 506. The rolling mechanism 7 includes a third support plate 701. The outer wall of the third support plate 701 is fixedly connected to the inner wall of the guide block 702. The outer wall of the guide block 702 is slidably connected to the wall of the second assembly groove 506. The outer wall of the third support plate 701 is fixedly connected to one end of the guide rod 703 close to the third support plate 701. The outer wall of the guide rod 703 is slidably connected to the wall of the second assembly groove 506. A fourth spring 704 is arranged on the outer wall of the guide rod 703. One end of the fourth spring 704 is fixedly connected to the outer wall of the third support plate 701, and the other end is fixedly connected to the wall of the second assembly groove 506. The inner wall of the third support plate 701 is rotatably connected to the outer wall of the rolling wheel 706 through a rotating shaft. The rolling mechanism 7 further includes a third scraper 705. The outer wall of the third scraper 705 is hingedly connected to the wall of the second assembly groove 506 through a rotating shaft.

The inner wall of the third scraper 705 contacts the outer wall of the rolling wheel 706. When the rolling wheel 706 rolls on the wall surface of the wall, the third support plate 701 squeezes the fourth spring 704 and slides on the inner wall of the second assembly groove 506. The rolling wheel 706 drives the third scraper 705 to contract, so that while the third scraper 705 scrapes the repair material attached to the outer wall of the rolling wheel 706, it evenly scrapes and levels the repair material extruded from the output port 504, which is convenient for the caulking mechanism 6 to scrape the repair material into the crack and collect the excess repair material outside the crack at the same time;

[0034] The number of the caulking mechanisms 6 and the rolling mechanisms 7 is three groups each.

[0035] The working principle of this embodiment is as follows: When the concrete building wall crack bioremediation device is put into use, the repair material is filled into the storage bin 1 from the filling port 3. The repair material ejects the telescopic block 505 in the storage bin 1 and slides on the inner wall of the support block 501. Align the repair device with the wall crack, press it, and start the motor 8. Drive the support block 501 to rotate through the drive plate 9. The telescopic block 505 squeezes the repair material inside the storage bin 1, so that the repair material enters the material conveying pipe 2 and then enters the output bin 4, and is extruded from the output port 504 through the diversion hole 502. The caulking mechanism 6 rolls the repair material into the crack. The rolling wheel 706 squeezes the third support plate 701 through the fourth spring 704 to roll the repair material outside the crack, which is convenient for the caulking mechanism 6 to scrape and collect, and at the same time rolls the repair material filled inside the crack, so that the repair material is filled to the deep part of the crack. The third scraper 705 rolls and guides the repair material outside the crack and scrapes the repair material attached to the outer wall of the rolling wheel 706 until the filling is completed.

[0036] Embodiment 2, please refer to Figures 4 - 6, the present invention provides a technical solution: The seam-filling mechanism 6 includes a first support rod 601. The outer wall of the first support rod 601 is slidably connected to the inner wall of the first support plate 507, and the outer wall of the first support rod 601 is fixedly connected to the inner wall of the second support plate 602. One end of the first support rod 601 away from the second support plate 602 is fixedly connected to the outer wall of the first scraper 603;

[0037] The seam-filling mechanism 6 further includes a second support rod 604. Both ends of the second support rod 604 are fixedly connected to the wall of the first assembly groove 503, and a support mechanism 61 is provided on the outer wall of the second support rod 604;

[0038] The support mechanism 61 includes a third support rod 611. The number of the third support rods 611 is two groups. The inner wall of one group of the third support rods 611 close to the wall of the first assembly groove 503 is rotatably connected to the outer wall of the second support rod 604, and the inner wall of the other group of the third support rods 611 away from the wall of the first assembly groove 503 is fixedly connected to the outer wall of the second support rod 604.

[0041] The working principle of this embodiment is as follows: The second support plate 602 drives the first support rod 601 to slide on the inner wall of the first support plate 507 through the swing mechanism 62. The two groups of first scrapers 603 face each other. One of the first scrapers 603 rolls the repair material on its back and rolls the repair material into the crack. At the same time, the second support plate 602 presses down and drives the other group of first scrapers 603 to scrape and collect the repair material that has not been filled into the crack through the swing mechanism 62. The swing mechanism 62 drives the third support rod 611 to deflect obliquely, and adjusts through the fourth support rod 613 and the rotating rod 615, driving the rotating wheel 6161 to tilt to one side of the first scraper 603 that rolls the repair material, assisting in rolling the repair material into the wall crack. At the same time, the second scraper 6162 scrapes the repair material that has not entered the crack by being squeezed by the second spring 6163, leaving scratches on the surface of the repair material, which is convenient for the first scraper 603 responsible for scraping to scrape and collect the repair material.
