[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 The present invention provides an embodiment of a high-efficiency concrete pouring device for bridge engineering, comprising a mixing barrel 1, the bottom surface of which is fixedly connected to a conical lower hopper 2. The mixing barrel 1 is used to store and mix concrete raw materials. The conical lower hopper 2 allows concrete to flow smoothly into the discharge assembly 3. The conical structure helps reduce concrete retention, thereby improving pouring efficiency. The inclined wall of the conical lower hopper 2 is fixedly connected to multiple groups of support legs 21 distributed in an array. Reinforcement rods 22 are fixedly connected between the multiple groups of support legs 21. The support legs 21 serve to support and stabilize the entire pouring device, and the reinforcement rods 22 strengthen the connection between the support legs 21, providing additional structural stability.

The connecting pipe 31, the hollow sphere 32 and the discharge pipe 33 are used for the outflow of concrete raw materials. The inner wall of the hollow sphere 32 is rotatably connected to a rotating shaft 34, and the outer wall of the rotating shaft 34 is fixedly connected to an arc plate 35, which fits the inner wall of the hollow sphere 32. There are multiple groups of arc plates 35, and multiple groups of arc plates 35 are arrayed on the outer wall of the rotating shaft 34. The arc plates 35 fit tightly with the inner wall of the hollow sphere 32 to form a closed space, which effectively prevents leakage or loss of concrete during discharge, and at the same time, the speed of concrete discharge is adjusted by the rotation of the arc plates 35. A motor 36 is fixedly connected to the outer wall of hollow sphere 32. The output shaft of motor 36 extends through and rotatably connects to the inner wall of hollow sphere 32. The output shaft of motor 36 is fixedly connected to the end of shaft 34. Motor 36 drives shaft 34 to rotate, controlling the concrete flow rate via curved plate 35, making the discharging process more stable and reducing the problem of jamming caused by excessive concrete viscosity.

[0033] Reference Figure 1 、 Figure 3 The top of the mixing barrel 1 is provided with four sets of symmetrically arranged slots 4, and a cross plate 41 is fixedly connected to the inside of the slots 4. The slots 4 and the cross plate 41 are used to provide positioning support for the mixing assembly 5, ensuring the stable operation of the mixing assembly 5. The bottom surface of the cross plate 41 is provided with a mixing assembly 5, which includes a drive shaft 51, which is rotatably connected to the bottom surface of the cross plate 41. The side walls of the drive shaft 51 are fixedly connected to multiple sets of mixing frames 52 distributed in an array. The drive shaft 51 is used to drive the mixing frames 52 to rotate and achieve mixing of the concrete. The bottom surface of the mixing frame 52 is set to an inclined shape. The inclined bottom surface of the mixing frame 52 can fit the shape of the conical lower hopper 2, so that the concrete in the conical lower hopper 2 can be mixed simultaneously. The side walls of the mixing frame 52 are fixedly connected to the drive shaft 51. Multiple sets of inclined plates 53 are distributed in an array. The function of the inclined plates 53 is to reinforce the mixing frame 52 and, through a relatively fixed angle, increase the contact area with the material, thereby generating stronger material fluidity and preventing material accumulation or uneven mixing. A second motor 54 is fixedly connected to the surface of the cross plate 41. The output shaft of the second motor 54 extends through and is rotatably connected to the bottom surface of the cross plate 41. The output shaft of the second motor 54 is fixedly connected to the top of the drive shaft 51. The second motor 54 is responsible for driving the drive shaft 51 to rotate, thereby realizing the operation of the entire stirring assembly 5.

[0034] Working Principle: First, concrete is poured into the mixing drum 1. Then, motor 2 54 is started, driving the mixing assembly 5 to begin operation. The mixing frame 52 rotates under the drive shaft 51, stirring the concrete. During the mixing process, the mixing frame 52 is reinforced by the inclined plate 53. At a relatively fixed angle, the contact area with the material is increased, resulting in stronger material flow and preventing material accumulation or uneven mixing.

[0035] Next, start the motor 36, the shaft 34 begins to rotate, driving the curved plate 35 to rotate on the inner wall of the hollow sphere 32. By adjusting the rotation speed of the shaft 34, the rotation speed of the curved plate 35 can be controlled, thereby adjusting the speed and flow rate of the concrete outflow, making the material feeding process more stable and reducing the jamming problem caused by the excessive viscosity of the concrete.
