In water conservancy project construction, concrete is the basic material for constructing dams, levees, sluices, channels, and other hydraulic structures, providing the required structural strength and stability, and playing the roles of impact resistance, erosion resistance, and waterproofing to ensure the safe operation of water conservancy projects. Therefore, the application of concrete in water conservancy project construction requires careful design and strict quality control to ensure the safety, reliability, and durability of the project.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1-3, the present utility model provides a technical solution: a concrete mixing device for water conservancy project construction, including the main body 1 of the concrete mixing device. A horizontally arranged first mixing tank 14 and a vertically arranged second mixing tank 13 are provided on the main body 1 of the concrete mixing device. A first driving rod 7 and a second driving rod 12 are respectively arranged in the first mixing tank 14 and the second mixing tank 13. A feeding seat 2 is arranged on the side of the main body 1 of the concrete mixing device, and the bottom of the feeding seat 2 is inclined and communicated with the first mixing tank 14. This structure can carry out the feeding treatment of concrete mixing materials through the feeding seat 2, and carry out primary mixing and secondary mixing through the first mixing tank 14 and the second mixing tank 13 respectively, which can improve the concrete mixing effect. A first spiral agitator 5 and a second spiral agitator 17 are respectively installed on the first driving rod 7 and the second driving rod 12, and bevel gear transmission gears 8 that mesh with each other are respectively installed at the ends of the first driving rod 7 and the second driving rod 12, so that the first mixing tank 14 and the second mixing tank 13 are started synchronously. A cooling mechanism 15 is installed on the outer ring of the first mixing tank 14. A fixing plate 11 is welded and fixed at the upper end of the second mixing tank 13, and a mounting cover 9 is fixed by screwing at the upper end of the fixing plate 11. And a bearing seat 10 is fixedly installed in the mounting cover 9 by screwing. This structure can stably install the mounting cover 9 on the second mixing tank 13 by the fixing plate 11. A water guide pipe 4 also penetrates through the top of the first mixing tank 14 movably, and a nozzle seat 3 is installed at the bottom of the water guide pipe 4. Nozzles 18 are installed at intervals on the side of the nozzle seat 3, and a fastening seat 19 is also fixed by screwing at the bottom of the nozzle seat 3, and the fastening seat 19 is tightly clamped with the inner wall of the first mixing tank 14. This structure can make the fastening seat 19 separate from the first mixing tank 14 by making the water guide pipe 4 move relative to the first mixing tank 14, so that the nozzle seat 3 enters the first mixing tank 14, realizing the water adding treatment of the first mixing tank 14, and hiding the nozzle seat 3 during the mixing process to avoid the nozzle seat 3 being blocked. A first discharge port 6 is arranged at the opening end of the first mixing tank 14, and the first discharge port 6 is above the upper end of the upper opening of the second mixing tank 13. And a second discharge port 16 is opened at the bottom of the second mixing tank 13. The bearing seat 10 is penetrated and matched with the first driving rod 7 and the second driving rod 12, and the mounting cover 9 covers the bevel gear transmission gears 8. This structure can protect the bevel gear transmission gears 8 by the mounting cover 9. Driven by a stepping motor, the first driving rod 7 can drive the first spiral agitator 5 in the reverse or forward direction to carry out the primary mixing of concrete. And the first driving rod 7 drives the second driving rod 12 to rotate through the meshing between the bevel gear transmission gears 8, and the second driving rod 12 drives the second spiral agitator 17 in the forward and reverse directions to carry out the secondary mixing of concrete. The bottom of the second mixing tank 13 is a conical structure, and the second spiral agitator 17 is also arranged in the second discharge port 16. This structure can prevent the concrete from being discharged by the first spiral agitator 5 when the first mixing tank 14 mixes the concrete, and at this time, the second mixing tank 13 discharges the concrete from the second discharge port 16 through the second spiral agitator 17.When the first mixing tank 14 discharges concrete, the second mixing tank 13 cannot discharge concrete.

[0018] Working principle: When using this concrete mixing device for water conservancy project construction, first, the concrete mixing material is added to the first mixing tank 14 from the feeding seat 2 in proportion. The first driving rod 7 rotates driven by the stepping motor, driving the first spiral agitator 5 to rotate, and mixing the concrete raw materials. Then, the water guide pipe 4 is moved downward, so that the nozzle seat 3 extends into the first mixing tank 14, and water is added to the first mixing tank 14 through the nozzle 18. After the water addition is completed, the water guide pipe 4 is raised again, and the fastening seat 19 is clamped into the first mixing tank 14. Cooling water is introduced into the cooling mechanism 15 to cool the first mixing tank 14. The first driving rod 7 drives the second driving rod 12 through the umbrella-shaped transmission gear 8. The second spiral agitator 17 rotates in the second mixing tank 13. When the first mixing tank 14 is mixing, the second mixing tank 13 is in the discharging state. When the first mixing tank 14 discharges through the first discharge port 6, the first spiral agitator 5 is driven in the reverse direction, so that the concrete is pushed out from the first discharge port 6 and enters the second mixing tank 13. At this time, the second spiral agitator 17 in the second mixing tank 13 also rotates in the reverse direction, so that the concrete entering the second mixing tank 13 is subjected to secondary mixing. Until the first mixing tank 14 finishes discharging and starts the next round of concrete mixing again, the second mixing tank 13 discharges. The installation cover 9 stably positions the bearing seat 10 through the fixing plate 11, so that the bearing seat 10 respectively rotates and positions the first driving rod 7 and the second driving rod 12, realizing the efficient operation of the main body 1 of the concrete mixing device, making the water conservancy project construction more efficient, and thus completing a series of operations.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
