An asphalt tank 3 is located above the outer end face of the mixing chamber 1. An inlet 301 is provided at the top of the asphalt tank 3, and an electric heating wire 17 is embedded in the tank wall. The bottom of the asphalt tank 3 is connected to the head end of a conveying pipe 8 in a spraying assembly. The conveying pipe 8 is inserted into the upper part of the mixing chamber 1, and the tail end of the conveying pipe 8 is connected to the inner end face of the mixing chamber 1. Several spray pipes 9 are provided at the bottom of the conveying pipe 8. A spiral conveying shaft 10 is built into the conveying pipe 8 and connected to the output end of a spraying motor 11. The spraying motor 11 is installed on the outer end face of the mixing chamber 1.
[0018] In this embodiment, a drive box 12 of the drive mechanism is installed below the outer end face of the mixing tank 1. A drive motor 13 is installed on the outside of the drive box 12. The output end of the drive motor 13 is connected to one of the three output shafts 4. The three output shafts 4 are inserted into the lower part of the mixing tank 1. The shafts of the output shafts 4 are alternately provided with stirring rods 5. Each output shaft 4 is meshed with a shaft transmission gear 401, which is located inside the drive box 12.

Aggregates with diameters that meet the mixing requirements fall from the screen holes into the mixing box 1 below. The drive motor 13 is started to drive the three output shafts 4 to rotate. The staggered stirring rods 5 perform preliminary mixing of various aggregates in the box. The spray motor 11 is started to drive the screw conveyor shaft 10 to rotate. The asphalt heated and insulated by the asphalt tank 3 enters the conveying pipe 8 and then enters the spray pipe 9 in sequence from the conveying pipe 8. Finally, it is evenly sprayed onto the surface of the aggregates. After the drive motor 13 drives the aggregates and asphalt to continue mixing for a period of time, all motors are turned off, the positioning bolts 16 are unscrewed, and the arc-shaped gate 14 is opened by the handwheel 15 to unload the material.
[0021] This invention uses a screening and vibration mechanism to screen out qualified aggregates and put them into a mixing box 1. Then, the aggregates are initially mixed by a driving mechanism. During the mixing process, the spraying component can evenly spray the asphalt in the asphalt tank 3 onto the aggregates, improving the mixing efficiency of asphalt and aggregates. This saves a lot of manpower and time costs while making the asphalt mixture more uniform.
