A material receiving cover 404 is arranged below the scraper 403, and the material receiving cover 404 is fixedly connected to the mobile body 1. A sliding groove adapted to the L-shaped moving block 402 is opened on the surface of the mobile body 1, and the spring 401 and the L-shaped moving block 402 are both located in the sliding groove. The L-shaped moving block 402 and the mobile body 1 are slidably connected through the sliding groove, and the scraper 403 is tightly fitted to the surface of the compacting wheel 3.

[0030] In this embodiment: the compaction grouting device for municipal road and bridge construction, when in use, after the grouting of the grouting mechanism 2 is completed, the compacting wheel 3 can compact the soil by moving the vehicle body 1, and when the compacting wheel 3 rolls, the spring 401 rebounds and drives the L-shaped moving block 402 to move, and the L-shaped moving block 402 moves and drives the scraper 403 to move, so that the scraper 403 is closely fitted with the surface of the compacting wheel 3, and as the compacting wheel 3 rolls, the slurry or impurities attached to the compacting wheel 3 are scraped off and fall into the inside of the material receiving cover 404 for collection, thereby avoiding the uneven compaction of the ground due to the slurry or impurities on the surface of the compacting wheel 3, improving the work quality, and solving the problem of solidification caused by untimely cleaning, thereby improving the use effect of the device and meeting actual use needs.

[0031] Going further;

[0032] In an optional embodiment, the interior of the receiving cover 404 is rotatably connected with a spiral blade 405 through a bearing, a driving motor 406 is fixedly installed on one side of the receiving cover 404 by bolts, the output end of the driving motor 406 is fixedly connected to one end of the spiral blade 405, a discharge port is provided on the side of the receiving cover 404 away from the driving motor 406, a collecting tube 407 is fixedly provided on the surface of the receiving cover 404 near the discharge port, a conveying pipe 408 is fixedly connected to the bottom end of the collecting tube 407, a storage box 411 is fixedly installed on the interior of the mobile body 1 by bolts, and the storage box 411 1 is fixed with a material extraction pump 409, a delivery pipe 412 is fixed with the output end of the material extraction pump 409, the other end of the delivery pipe 412 is fixedly connected with the storage box 411, the other end of the delivery pipe 408 is fixedly connected with the input end of the material extraction pump 409, a battery 410 is fixedly installed on the upper surface of the mobile body 1, the delivery pipe 412 is connected with the storage box 411, the delivery pipe 408 is connected with the collecting tube 407, the battery 410 and the driving motor 406 are electrically connected through a wire, a material discharge port is opened on the lower surface of the storage box 411, and a sealing plate is provided at the material discharge port.

[0033] In this embodiment: the drive motor 406 is then powered by the battery 410 to start the drive motor 406 for operation, and the spiral blade 405 is driven by the drive motor 406 to rotate. As the spiral blade 405 rotates, the slurry or impurities inside the material receiving cover 404 are transported to the collecting tube 407, and then the extraction pump 409 is powered by the battery 410, and the extraction pump 409 is started, and the slurry inside the collecting tube 407 is extracted through the delivery pipe 1 408, and discharged to the inside of the receiving box 411 through the delivery pipe 2 412, completing the collection and preventing the slurry from falling into the inside of the material receiving cover 404. Since the material receiving cover 404 is designed as an open structure, overflow from the open part is avoided, thereby further improving the use effect of the device. When the slurry collected in the receiving box 411 needs to be discharged, the slurry can be discharged by opening the sealing plate of the receiving box 411.

[0034] Further,

[0035] In an optional embodiment, a stirring and crushing assembly 5 is installed on the scraping assembly 4, and the stirring and crushing assembly 5 includes a sprocket 501 fixed to the output end of the driving motor 406 and a crushing rod 504 rotatably connected to the inside of the storage box 411 through a bearing, one end of the crushing rod 504 passes through the storage box 411 and the mobile body 1 in sequence, and extends to the outside of the mobile body 1, and is fixedly connected to the sprocket 2 503 arranged on the outside of the mobile body 1 by screws, a chain 502 is meshed between the sprocket 1 501 and the sprocket 2 503, and one end of the crushing rod 504 is rotatably connected to the mobile body 1 through a bearing.

[0036] In this embodiment: as the driving motor 406 runs, it drives the sprocket 1 501 to rotate. Since the sprocket 1 501 and the sprocket 2 503 are meshed and connected by the chain 502, the sprocket 2 503 is driven to rotate. The rotation of the sprocket 2 503 drives the breaking rod 504 to rotate. The breaking rod 504 can continuously stir the slurry inside the storage box 411, thereby reducing the slurry solidification efficiency. At the same time, when the slurry solidifies, the breaking rod 504 has a breaking effect to prevent the solidified slurry from being difficult to discharge from the storage box 411, thereby improving the practicality and flexibility of the device.

[0037] The working principle and use process of the utility model are as follows: when the compaction grouting device for municipal road and bridge construction is in use, after the grouting mechanism 2 completes the grouting, the compaction wheel 3 can compact the soil (not shown in the figure) by moving the vehicle body 1. When the compaction wheel 3 rolls, the spring 401 rebounds and drives the L-shaped moving block 402 to move. The L-shaped moving block 402 moves and drives the scraper 403 to move, so that the scraper 403 is closely fitted to the surface of the compaction wheel 3. As the compaction wheel 3 rolls, the slurry or impurities attached to the compaction wheel 3 are scraped off, and The impurities dropped into the receiving hood 404 are collected, thereby avoiding the uneven compaction of the ground due to the slurry or impurities on the surface of the compacting wheel 3, improving the work quality, and solving the problem of solidification due to untimely cleaning, improving the use effect of the device, and meeting the actual use needs. Subsequently, the drive motor 406 is powered by the battery 410 to start the drive motor 406 for operation, and the spiral blade 405 is driven by the drive motor 406 to rotate. As the spiral blade 405 rotates, the slurry or impurities in the receiving hood 404 are transported to the collection hood 404. The slurry in the collecting cylinder 407 is drawn out through the conveying pipe 1 408, and is discharged to the inside of the receiving box 411 through the conveying pipe 2 412 to complete the collection, so as to prevent the slurry from falling into the inside of the receiving cover 404. Since the receiving cover 404 is designed with an open structure, it can avoid overflowing from the open part, further improving the use effect of the device. With the operation of the driving motor 406, the sprocket 1 501 is driven to rotate. Since the sprocket 1 501 and the sprocket 2 503 The chain 502 is meshed and connected to drive the sprocket 503 to rotate, and the rotation of the sprocket 503 drives the breaking rod 504 to rotate. The breaking rod 504 can continuously stir the slurry inside the storage box 411, thereby reducing the slurry solidification efficiency. At the same time, when the slurry solidifies, the breaking rod 504 has a breaking effect to avoid the difficulty of discharging the solidified slurry from the storage box 411, thereby improving the practicability and flexibility of the device. When the slurry collected in the storage box 411 needs to be discharged, the slurry can be discharged by opening the sealing plate of the storage box 411.
