[0014] Compared with the prior art, this utility model has the following features and beneficial effects:
[0015] 1. This utility model uses a mobile vehicle to drive the spraying assembly to move in a circular motion along the annular guide rail, so that the spray head can cover the entire surface of the silo wall. This achieves all-round and uniform spraying of the shallow circular silo wall concrete, reduces manual input, lowers labor intensity, ensures uniform wetting of the concrete surface, avoids the risk of cracking caused by local dryness, and improves the overall quality of concrete and construction efficiency.

Detailed Implementation
[0023] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0024] Example 1:
[0025] See the examples. Figures 1 to 5 As shown, this utility model discloses a concrete spraying and curing device for slipform construction of shallow circular silos, including a silo 1 and a spraying assembly 2. The silo 1 is the body of the shallow circular silo and has a cylindrical structure, used for long-term storage or transfer of grain. The spray assembly 2 is used for spray curing of concrete in shallow circular silo slipform construction. It is set on the periphery of the silo 1. The spray assembly 2 includes a guide rail 26 that stably rotates the moving ring 27. The guide rail 26 is fixedly installed on the bottom of the outer side of the silo 1. The top of the guide rail 26 is movably connected to the moving ring 27, which drives two sets of support blocks 21 to rotate. The top left and right sides of the moving ring 27 are fixedly connected to support blocks 21 that support multiple sets of spray heads 28. The guide rail 26 and the moving ring 27 are movably connected to drive the two sets of support blocks 21 to rotate stably. The top of the moving ring 27 is fixedly installed with a conveying pipe 25 that delivers water to the conveying pipe 29. The conveying pipe 25 passes through the bottom of the two sets of support blocks 21. The left side of the left support block 21 is fixedly installed with a connecting block 24 that connects the moving vehicle 23 to the support block 21 and the moving ring 27.
[0026] Furthermore, a moving trolley 23 that drives the moving ring 27 to rotate is fixedly installed on the left side of the connecting block 24. A transmission pipe 29 that delivers water to the spray head 28 is fixedly connected to the top of the conveying pipe 25 and inside both sets of support blocks 21. Multiple spray heads 28 that spray water onto the outer wall of the tank 1 are fixedly connected to the inner sides of both sets of support blocks 21. This connects the connecting block 24 to drive the moving ring 27 and the two sets of support blocks 21 to rotate, thereby driving the multiple spray heads 28 to spray water evenly. The multiple spray heads 28 are respectively connected to and fixedly connected to the two sets of transmission pipes 29. The conveying pipe 25, guide rail 26, and moving ring 27 are all circular. The mobile vehicle 23 is equipped with a water storage tank at the rear and a mounting cover at the top of the mobile vehicle 23 that connects to the storage tank. The mounting cover can be opened to add water. Inside the storage tank, there is a water pump that pumps water into the delivery pipe 25. A connecting pipe 22 that delivers water into the delivery pipe 25 is fixedly connected to the right side of the water pump. The connecting pipe 22 passes through and is fixedly connected to the right side of the mobile vehicle 23. The right side of the connecting pipe 22 is fixedly connected to and communicates with the delivery pipe 25. There are two sets of moving rings 27. The other set of moving rings 27 is fixedly connected to the top of the two sets of support blocks 21. The two sets of support blocks 21 are respectively fixedly connected between the two sets of moving rings 27.
[0027] An adjustment assembly 3 is provided on the outer side of the multiple sets of spray heads 28. The adjustment assembly 3 includes two sets of guide blocks 31 that drive multiple sets of moving blocks 34 to move. The two sets of guide blocks 31 are slidably connected to the outer side of the two sets of support blocks 21 through positioning blocks 35 that are fixedly connected to the inner side near the upper and lower ends. The positioning blocks 35 are T-shaped and slidably connected inside the support blocks 21. Therefore, the movement distance of the guide blocks 31 can be limited by the positioning blocks 35 to prevent them from falling off and to increase stability. Multiple sets of moving blocks 34 that drive connecting rods 36 to move are fixedly connected to the inner side of each set of guide blocks 31. Connecting rods 36 that drive adjusting heads 37 to move are fixedly connected to the inner side of each set of moving blocks 34. Adjusting heads that can move inward to reduce the distance between the adjusting head 37 and the spray head 28 and thus reduce the amount of spray are fixedly connected to the inner side of each set of connecting rods 36. 37. The outer middle of each of the two sets of support blocks 21 is fixedly installed with a hydraulic rod 32 that drives the guide block 31 to move via a fixing block 33. The output ends of the two sets of hydraulic rods 32 are respectively fixedly connected to the outer sides of the two sets of guide blocks 31. The inner ends of the multiple sets of spray heads 28 are all provided with concave conical shapes and are connected to the transmission pipe 29. The multiple sets of adjusting heads 37 are all set with conical shapes. The multiple sets of adjusting heads 37 slide inside the concave conical shapes of the inner ends of the multiple sets of spray heads 28. By setting the conical shape, when the adjusting head 37 moves into the concave conical shape of the spray head 28, the distance between the adjusting head 37 and the spray head 28 can be reduced, thereby reducing the amount of spraying outward, achieving the effect of controlling the amount of spraying according to actual needs. The multiple sets of positioning blocks 35 are all set with T-shapes. The T-shape setting can limit the distance of movement of the positioning block 35.
[0028] Example 2:
[0029] Specific usage method of this utility model:
[0030] Step 1: First, connect the external power supply and switch to the electrical equipment in this device. Start the water pump in the storage tank at the rear of the mobile vehicle 23 to draw the stored water out through the connecting pipe 22 and transport it to the conveying pipe 25. Since the conveying pipe 25, guide rail 26, and moving ring 27 are all circular, and the conveying pipe 25 is fixed to the top of the moving ring 27, the water can be evenly distributed along the annular conveying pipe 25. Subsequently, the water is transported to multiple sets of spray heads 28 through the transmission pipe 29 at the top of the conveying pipe 25. When the mobile vehicle 23 is started, it rotates around the outer wall of the silo 1, which drives the connecting block 24 to rotate. This causes the moving ring 27 to rotate along the guide rail 26 fixed to the bottom of the outer side of the silo 1. The support block 21, which is fixedly connected between the two sets of moving rings 27, rotates synchronously. Multiple sets of spray heads 28 installed on the inner side of the support block 21 also rotate around the outer wall of the silo 1. The spray heads 28 spray the water delivered by the transmission pipe 29 evenly onto the concrete surface of the outer wall of the silo 1, thus achieving a surround spray curing of the concrete.
[0031] Step 2: When the spray volume needs to be adjusted, the hydraulic rod 32 fixed to the middle of the outer side of the support block 21 is activated. The output end of the hydraulic rod 32 retracts inward to pull the guide block 31. The guide block 31 slides on the outer side of the support block 21 through the positioning block 35 on the inner side. Since the positioning block 35 is T-shaped, it is restricted by the internal structure of the support block 21 when sliding, which can ensure that the guide block 31 moves stably and will not fall off. The movement of the guide block 31 drives the multiple sets of moving blocks 34 fixed on its inner side to move synchronously. The moving blocks 34 then drive the adjusting head 37 to move into the conical shape of the inner end of the spray head 28 through the connecting rod 36. Since both the adjusting head 37 and the inner end of the spray head 28 are conical, as the adjusting head 37 goes deeper, the water passage between it and the spray head 28 narrows, thereby reducing the amount of water sprayed outward. Conversely, the output end of the hydraulic rod 32 pushes the adjusting head 37 to move outward, the water passage widens, and the amount of water sprayed increases. This achieves the purpose of flexibly controlling the spray volume according to the actual maintenance needs.
[0032] Step 3: Throughout the entire process, the rotation of the moving ring 27 achieves full-circumferential spraying. Combined with the precise control of the spraying volume by the adjusting component 3, this ensures that the concrete in the shallow circular silo 1 receives uniform and appropriate curing during slipform construction, thus guaranteeing the strength and quality of the concrete.
