[0022] See also Figures 1 to 3 The utility model is a bridge deck concrete distribution device, comprising a hopper 1 and a mobile frame 2; the upper portion of the mobile frame 2 is connected to the hopper 1; the lower opening of the hopper 1 is closed by a closing plate; and a plurality of distribution pipes 3, the upper ends of the distribution pipes 3 passing through the closing plate;
[0023] The first rotating shaft 5 is further provided with a first stirring rod 6, the front end of which is rotatably connected to the front side of the hopper 1 and the rear end of which is rotatably connected to the rear side of the hopper 1. The first rotating shaft 5 is driven by a motor 4. The first rotating shaft 5 is evenly provided with a plurality of stirring assemblies along the axial direction. The stirring assemblies include a plurality of first stirring rods 6 perpendicular to the first rotating shaft 5 and radially distributed around the first rotating shaft 5. Two second stirring rods 7 are connected to the front side of the first stirring rod 6 and two second stirring rods 7 are also connected to the rear side.
[0024] It also includes a support rod 8; the support rod 8 is located below the first rotating shaft 5, and the front end of the support rod 8 is connected to the front side of the hopper 1, and the rear end is connected to the rear side of the hopper 1; it also includes multiple fixed rods 9; the fixed rods 9 are staggered with the stirring assembly and the lower end of the fixed rod 9 is connected to the support rod 8; the front side of the fixed rod 9 is connected to the third stirring rod 10 and the rear side is also connected to the third stirring rod 10, and the third stirring rod 10 is staggered with the second stirring rod 7.
[0025] In this embodiment, the movable frame 2 is moved, with the outlet of the distribution pipe 3 facing the location where concrete distribution is required. The motor 4 is started, which drives the first rotating shaft 5 to rotate. The first rotating shaft 5 drives the first stirring rod 6 and the second stirring rod 7 to rotate. Together with the third stirring rod 10, which is arranged alternately with the second stirring rod 7, the concrete fed into the hopper 1 is stirred, preventing the accumulation of concrete in the hopper from causing blockage and the sedimentation and stratification of the concrete that affects its quality. The stirred concrete flows through the distribution pipe 3 to the bridge deck, and then workers carry out the subsequent concrete leveling operation.
[0026] In this embodiment, the closing plate at the bottom of the hopper 1 is sloped toward the top of the distribution pipe 3. This prevents concrete from accumulating on the closing plate and allows for smoother flow toward the distribution pipe 3. The movable frame 2 comprises an upper frame and lower rollers, but may also employ other conventionally movable frame structures. A valve is installed on the distribution pipe 3 to open and close it. This allows it to be closed when distribution is temporarily unavailable and reopened when needed.

[0028] A helically arranged guide plate 15 is provided outside the second rotating shaft 12 .
[0029] In this embodiment, the motor 4 is started, and the motor 4 drives the first rotating shaft 5 to rotate, and the first pulley 11 rotates accordingly, thereby driving the second pulley 13 to rotate through the belt 14, and the second pulley 13 drives the second rotating shaft 12 to rotate, thereby driving the spiral guide plate 15 to rotate accordingly; the guide plate 15 rotates to further stir the concrete passing through it.
[0030] As a preferred embodiment, see Figure 3 、 Figure 4 The second rotating shaft 12 is evenly connected to a plurality of stirring columns 16 along the axial direction.

[0033] In this embodiment, the rotation of the second stirring rod 7 drives the fourth stirring rod 17 to rotate accordingly. The second stirring rod 7 is perpendicular to the fourth stirring rod 17. The rotation of the fourth stirring rod 17 can stir the concrete from another direction, further improving the overall effect of concrete mixing.
[0034] As a preferred embodiment, see Figure 1 , also includes a horizontal rotating shaft 18 and multiple spiral rollers 19; the horizontal rotating shaft 18 passes through the centers of the multiple spiral rollers 19 in sequence; the mobile frame 2 is connected to two brackets 20; the two ends of the horizontal rotating shaft 18 are respectively connected to the two brackets 20; the spiral roller 19 is higher than the lowest point of the mobile frame 2, and the spiral roller 19 is used to perform preliminary leveling of the concrete.
[0035] In this embodiment, the moving frame 2 consists of an upper frame and lower rollers, with the spiral roller 19 being taller than the rollers of the moving frame 2. As the moving frame 2 moves, the spiral roller 19 follows until it contacts concrete flowing from the distribution pipe 3 and deposited on the bridge deck. At this point, the spiral roller 19 begins to rotate and initially level the concrete, reducing the subsequent leveling workload for workers.
