[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides an embodiment: a grouting device for urban road subgrade settlement construction, including a mixing tank 1, a support leg 2 fixed to the outer wall of the mixing tank 1, an adjusting sleeve 8 movably disposed at the bottom end of the outer wall of the support leg 2, a locking bolt 11 disposed on one side of the adjusting sleeve 8, a fixing block 12 fixed on the other side of the adjusting sleeve 8, and a roller 13 installed at the bottom end of the fixing block 12, a tank cover 15 disposed at the top of the mixing tank 1, a feed inlet 14 disposed inside the tank cover 15, and a crossbeam 5 disposed at the top of the tank cover 15. A servo motor 16 is installed at the top of the mixing tank 1, a stirring rod 6 is installed at the bottom of the servo motor 16, and a stirring paddle 7 is installed at the bottom of the stirring rod 6. A discharge pipe 10 is provided at the bottom of the mixing tank 1, and a valve 9 is installed inside the discharge pipe 10. Four sets of support legs 2 are provided, and the four sets of support legs 2 are distributed in a ring at equal intervals on the outer wall of the mixing tank 1 to provide stable support for the mixing tank 1. The cross-section of the adjusting sleeve 8 is smaller than the cross-section of the scraper 3, and a sliding structure is formed between the adjusting sleeve 8 and the scraper 3 to facilitate the up and down movement and adjustment of the roller 13.

[0024] Specifically, such as Figure 1 and Figure 2 As shown, when transporting the device, the locking bolt 11 is rotated in sequence to unlock the adjusting sleeve 8, then the adjusting sleeve 8 is pushed to the bottom of the scraper 3, and then the locking bolt 11 is rotated in the opposite direction to lock the adjusting sleeve 8, thereby moving the roller 13 to the bottom and fixing it. Then the device is moved by the rolling of the roller 13.

[0025] A sleeve 4 is installed at the top of the outer wall of the stirring rod 6, and a scraper 3 is fixed on the outer wall of the sleeve 4. There are two sets of scrapers 3, and the two sets of scrapers 3 are symmetrically distributed about the central axis of the sleeve 4, which has a better scraping effect on the material on the inner wall of the stirring tank 1.

[0026] Specifically, such as Figure 1 As shown, when the mixing tank 1 mixes the cement mortar, the rotating mixing rod 6 will also drive the scraper rods 3 on both sides of the sleeve 4 to rotate. The rotation of the scraper rods 3 can scrape the inner wall of the mixing tank 1 to prevent the cement mortar from sticking together.

[0027] A locking block 17 is fixed to the bottom of the bucket lid 15, and a limiting ring 19 is fixed to one side of each locking block 17. A limiting block 18 is hinged to the outer wall of the mixing tank 1. The cross-section of the limiting block 18 is larger than the cross-section of the limiting ring 19. The limiting block 18 and the limiting ring 19 form a locking structure. The locking structure design facilitates the disassembly and assembly of the bucket lid 15 and the mixing tank 1. The locking blocks 17 are distributed in a ring at equal intervals at the bottom of the bucket lid 15, and the limiting blocks 18 are distributed in a ring at equal intervals on the outer wall of the mixing tank 1, so that the bucket lid 15 and the mixing tank 1 are stably installed together.

[0028] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, when it is necessary to open the mixing tank 1, the limiting block 18 is flipped in sequence to disengage from the outer wall of the limiting ring 19, and then the lid 15 is pushed upward to open the mixing tank 1 for cleaning. After cleaning the mixing tank 1, the lid 15 is locked together with the mixing tank 1, and the limiting block 18 is flipped in sequence to lock together with the limiting ring 19, so that the lid 15 and the mixing tank 1 can be assembled and used.

[0029] Working principle: When using this utility model, the cement mortar material is fed into the mixing tank 1 through the feed inlet 14 using the grouting device. The servo motor 16 is turned on, which drives the mixing paddle 7 to rotate via the mixing rod 6 to mix the cement mortar. After mixing, the valve 9 is opened to open the discharge pipe 10 to discharge the mortar. When preparing the slurry, the limiting blocks 18 are flipped to disengage from the outer wall of the limiting ring 19. The tank cover 15 is pushed upward to open the mixing tank 1 for cleaning. After cleaning, the tank cover 15 is locked back into the mixing tank 1. The limiting blocks 18 are flipped to disengage from the outer wall of the limiting ring 19. 8. Engage it with the limiting ring 19 for continued use. During the use of the device, the locking bolt 11 can be turned in sequence to unlock the adjusting sleeve 8. Then, push the adjusting sleeve 8 to the bottom of the scraper 3, and then turn the locking bolt 11 in the opposite direction to lock the adjusting sleeve 8. Move the roller 13 to the bottom and fix it. Then, move the device by rolling the roller 13. After moving it to the position of use, reverse the above steps to move the roller 13 above the scraper 3 so that the scraper 3 contacts the ground to support the device and make it stable for use.
