[0023] like Figures 1-5 As shown, a mixing machine for bridge construction includes a base frame 1. A feeding platform 2 is installed on the upper left side of the base frame 1. A hopper 6 is connected to the right side of the feeding platform 2 via an inclined conveyor belt 3. The height of the hopper 6 is higher than the height of the feeding platform 2, which facilitates feeding and reduces the labor intensity of workers. A vibrating screen 4 is installed on the top of the hopper 6.

[0024] The vibrating screen 4 is connected to a vibrating device, which includes a connecting rod 16 hinged to and located below the vibrating screen 4. The other end of the connecting rod 16 is hinged to a rotating wheel 15. The rotating wheel 15 is connected to a reduction gear transmission device 18 via a drive shaft 19. The reduction gear transmission device 18 is connected to a motor 17. The connecting rod 16 is located at an eccentric position on the rotating wheel 15. Specifically, when the vibrating screen 17 is started, the reduction gear transmission device 18 drives the drive shaft 19 to rotate. The rotation of the drive shaft 19 drives the rotating wheel 15 to rotate. Because the connecting rod 16 is located at an eccentric position on the rotating wheel 15, the connecting rod 16 moves up and down when the rotating wheel 15 rotates, ultimately causing the vibrating screen 4 to move up and down, thus performing the function of vibration screening.

[0025] The vibrating screen 4 is installed at a downward angle to the right, and a cleaning roller 5 is installed on the top right side of the hopper 6. Several cleaning brushes are distributed around the circumference of the cleaning roller 5. Specifically, the unqualified raw materials screened by the vibrating screen 4 reach the cleaning brushes and are driven out by the rotation of the cleaning roller 5, thus avoiding the accumulation of raw materials that would affect the screening effect and ensuring the quality of mixing.

Specifically, the rotating discs 1401 are rotated by rotating the spanners 1402, and then the blanking plates 1404 at the top of the rotating discs 1401 for closing the outlet at the bottom of the mixing box 9 are rotated to the lower side, the outlet is leaked, and the mixed construction material is discharged from the outlet.

[0028] The spraying pipes 11 are installed at the front and rear positions of the upper end of the hopper 6, the spraying pipes 11 are provided with water inlets 12 at the middle, and a plurality of atomizing nozzles are installed on the spraying pipes 11 at equal intervals, water is atomized and sprayed out through the atomizing nozzles, dust in the air is treated, dust pollution is reduced, and the construction environment is protected.

[0029] A plurality of rollers 10 are symmetrically installed at the bottom of the bottom frame 1, and transportation is facilitated.

[0030] The speed reduction transmission device 18 comprises a small sprocket wheel connected with the motor 17 and a large sprocket wheel connected with the transmission shaft 19, and the small sprocket wheel and the large sprocket wheel are connected together through a chain.

[0031] The action process of the utility model is as follows:

[0032] Firstly, the raw materials are placed on the feeding table 2 by hand, then the raw materials are transported to the vibrating screen 4 by the conveying belt 3 for screening, then the screened raw materials fall into the mixing box 9 from the hopper 6, the water inlet pipe 8 is connected with an external water source to provide sufficient water for the mixing process, and finally, the raw materials are fully stirred by the stirring device 13, and then the blanking device 14 is opened to discharge the mixing box 9.
