Description

Technical Field

[0001] This utility model relates to the field of water conservancy construction technology, and in particular to a concrete pouring device for water conservancy construction. Background Technology

[0002] Concrete pouring equipment in hydraulic engineering is used to transport concrete to a designated location and complete the pouring operation. This equipment is crucial for ensuring that concrete can be accurately and efficiently filled into the structure within the formwork, especially in hydraulic engineering projects with strict requirements for strength and stability.

[0003] While existing concrete pouring equipment, when used in conjunction with concrete pumps to transfer mixed concrete, can initially intercept aggregates using the pump's built-in screening plates, several inconveniences have emerged in actual operation. Because the concrete outlet is fixed, material tends to accumulate directly below it during pouring, gradually forming a buildup. This not only reduces the smoothness of concrete flow but also easily leads to blockages. To address this, users must frequently use shovels to manually level the accumulated concrete to ensure a continuous and even flow of material into the pump. However, even after leveling, large aggregates remain inside the pump, requiring further manual removal. This increases workload, prolongs construction time, and negatively impacts the final quality and efficiency of the concrete pour. Utility Model Content

[0004] The purpose of this utility model is to provide a concrete pouring device for water conservancy construction, which can avoid the problems of existing concrete pouring devices, when used in conjunction with a delivery pump, where the outlet position is fixed, easily leading to material accumulation and blockage, requiring frequent manual leveling and removal of large stones, increasing the workload and affecting construction efficiency and quality.

[0005] This utility model provides a concrete pouring device for water conservancy construction, including a mobile device. A concrete conveying pump is connected to the rear of the mobile device. A conveying hopper is installed on the rear of the concrete conveying pump. A screening plate is fixedly connected to the inner side of the conveying hopper. A mixing assembly is provided on the top of the concrete conveying pump. The mixing assembly includes a discharge bin. A fixing plate is fixedly connected to the top of the discharge bin.

[0007] In one specific implementation, a stirring rod is fixedly connected to the outer surface of the rotating rod, a positioning box is fixedly connected to the rear side of the concrete conveying pump, and an electric telescopic rod is fixedly connected to the inner cavity of the positioning box.

[0008] In one specific implementation, the output end of the electric telescopic rod extends to the outside of the left side of the positioning box, and an L-shaped rod is fixedly connected to the output end of the electric telescopic rod.

[0009] In one specific implementation, a connecting rod is rotatably connected to the bottom of the discharge hopper, a first push plate is fixedly connected to the outer surface of the connecting rod, and the top end of the L-shaped rod is slidably connected to the inner side of the first push plate.

[0010] In one specific implementation, a cover plate is connected to the end of the first push plate away from the L-shaped rod, and the top of the cover plate is used in conjunction with the discharge bin.

[0011] In one specific implementation, the cleaning assembly includes two discharge boxes, the inner cavity of which has a return cavity, and the inner cavity of the return cavity is fixedly connected to a filter screen.

[0015] The beneficial effects of this application are as follows: through the coordinated work of the mixing and cleaning components, not only is uniform mixing of concrete achieved, but also centralized storage of aggregates is effectively realized. In actual operation, the mixing component ensures thorough mixing of all concrete components, improving material consistency and structural strength. Simultaneously, while pushing large-volume aggregates to the storage area for centralized processing, the cleaning component automatically levels the concrete accumulated at the discharge port, effectively preventing blockages caused by material accumulation and ensuring smooth concrete flow. Furthermore, after the aggregates are centrally stored, the remaining concrete can be transported more efficiently via a concrete pump, significantly improving the efficiency and quality of the entire construction process. This reduces the need for manual intervention, improves construction safety and stability, and makes the entire pouring operation smoother and more efficient. Attached Figure Description

[0026] Existing concrete pouring devices, when used in conjunction with pumps, are prone to material accumulation and blockage due to their fixed outlet location. This necessitates frequent manual leveling and removal of large stones, increasing workload and impacting construction efficiency and quality. Therefore, the inventors have developed a concrete pouring device for hydraulic construction. Through the coordinated operation of mixing and cleaning components, it achieves uniform mixing of concrete and centralized storage of aggregates, while automatically leveling the concrete at the discharge outlet, preventing material accumulation and blockage. This not only improves the smoothness of concrete flow and construction efficiency but also reduces manual intervention, enhancing operational safety and stability, thereby resolving the aforementioned shortcomings.

[0027] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] Please refer to Figures 1 to 8 This utility model provides a concrete pouring device for hydraulic construction, including a mobile device 1. A concrete conveying pump 11 is connected to the rear of the mobile device 1. A conveying hopper 2 is installed on the rear of the concrete conveying pump 11. A screening plate 21 is fixedly connected to the inner side of the conveying hopper 2. The top of the screening plate 21 has several through cavities, the size of which can be changed according to the actual processing conditions. A mixing assembly 3 is provided on the top of the concrete conveying pump 11. The mixing assembly 3 includes a discharge bin 31, the bottom of which is fixed to the top of the concrete conveying pump 11. The top of the discharge hopper 31 is fixedly connected to a fixed plate 32, and the top of the fixed plate 32 is fixedly connected to a protective box 33. The inner cavity of the protective box 33 is equipped with a first motor 34, and the output shaft of the first motor 34 is fixedly connected to a rotating rod 35. The area of ​​the rotating rod 35 in contact with the protective box 33 is sealed. The outer surface of the rotating rod 35 is fixedly connected to a stirring rod 36, and the outer surface of the bottom of the stirring rod 36 is in contact with the bottom of the inner cavity of the discharge hopper 31. The rear side of the concrete pump 11 is fixedly connected to a positioning box 37, and the inner cavity of the positioning box 37 is fixedly connected to an electric telescopic rod 38.

[0029] Please refer to Figures 2 to 8 The output end of the electric telescopic rod 38 extends to the outer side of the left side of the positioning box 37. The output end of the electric telescopic rod 38 is fixedly connected to an L-shaped rod 311. The area where the electric telescopic rod 38 and the positioning box 37 are in contact is sealed. The bottom of the discharge bin 31 is rotatably connected to a connecting rod 39. The outer surface of the connecting rod 39 is fixedly connected to a first push plate 310. The top of the L-shaped rod 311 is slidably connected to the inner side of the first push plate 310. The end of the first push plate 310 away from the L-shaped rod 311 is connected to a cover plate 312. The top of the cover plate 312 is used in conjunction with the discharge bin 31. The cover plate 312 is in contact with the discharge cavity at the bottom of the discharge bin 31.

[0030] Specifically, during the concrete mixing process, the first motor 34 is started first, which drives the rotating rod 35 and the mixing rod 36 on it to rotate, ensuring that the concrete is fully mixed. After mixing is completed, the electric telescopic rod 38 is started, and its output end retracts to drive the L-shaped rod 311 to move to the right, which in turn pushes the first push plate 310 to move to the left around the connecting rod 39 as the axis, so that the mixed concrete flows smoothly to the conveyor hopper 2 for transmission.

[0031] Please refer to Figures 2 to 8 The outer surface of the conveying hopper 2 is provided with a cleaning assembly 4, which includes two dispensing boxes 41. The opposite sides of the two dispensing boxes 41 are fixedly connected to the outer surfaces of the left and right sides of the conveying hopper 2. The inner cavity of the dispensing box 41 has a return cavity 42, and a filter screen is fixedly connected to the inner cavity of the return cavity 42. The pore size of the filter screen can be changed according to the actual processing conditions. Fixed cavities are provided on the upper and lower sides of the left and right sides inside the conveying hopper 2, while the inner cavity of the dispensing box 41 has a feeding cavity adapted to the fixed cavity. An inclined plate is fixedly connected to the bottom of the inner cavity of the dispensing box 41. This facilitates the reflow of liquid concrete into the conveyor hopper 2 for concrete pouring. A long box 43 is fixedly connected to the front side of the conveyor hopper 2. A threaded rod 44 is rotatably connected to the inner cavity of the long box 43. The outer surface of the threaded rod 44 is provided with external threads. A second motor 45 is fixedly connected to the inner cavity of the long box 43. The output shaft of the second motor 45 is fixedly connected to the left end of the threaded rod 44. A threaded plate 46 is threadedly connected to the outer surface of the threaded rod 44. The area of ​​the threaded plate 46 in contact with the threaded rod 44 is provided with matching internal threads. The front and rear sides of the threaded plate 46 are slidably connected to the inner cavity of the long box 43.

[0032] The bottom of the threaded plate 46 extends to the outside of the long box 43 and is fixedly connected to the second push plate 47. The bottom of the long box 43 is provided with a movable cavity that works in conjunction with the threaded plate 46, and the second push plate 47 works in conjunction with the screening plate 21.

[0033] Specifically, when concrete enters the conveyor hopper 2, it first passes through the screening plate 21 to intercept large stones. At this time, the second motor 45 is activated, driving the threaded rod 44 to rotate. Utilizing the threaded transmission principle, the threaded plate 46 moves left and right, simultaneously driving the second pusher plate 47 to move synchronously. The movement of the second pusher plate 47 not only helps to level the concrete, preventing it from accumulating on the screening plate 21, but also effectively pushes the stones into the discharge box 41 for centralized storage. The leveled concrete then returns to the conveyor hopper 2 through the return chamber 42 for continued transport. Simultaneously, the filter screen within the return chamber 42 further intercepts stones, ensuring that only materials of suitable size enter the conveyor hopper 2 for subsequent use. This optimization makes the entire process smoother, improving work efficiency and concrete quality.

[0034] In summary, the working principle of a concrete pouring device for water conservancy construction according to this utility model embodiment is as follows: First, the user moves the mobile device 1 and the concrete conveying pump 11 to the application scene where pouring is required. Then, the external pipe is connected to the rear side of the conveying hopper 2 to facilitate the pouring of concrete to the required area. During the pouring process, the mixing component 3 is used to mix the concrete evenly. After mixing, the cleaning component 4 is used to level the conveyed concrete to avoid blockage during the conveying process. The screened stones are stored in a centralized manner, and after pouring, the concrete is spread manually. After leveling, the plate vibrator is used to vibrate from the foot of the slope to the top of the slope. For areas that are difficult to compact, an immersion vibrator is used to vibrate again. After the concrete is compacted, it is leveled and manually finished three times to ensure that the flatness of the concrete surface meets the design requirements, thereby achieving the purpose of concrete pouring and facilitating use.
