The shell 10 is provided with a feed port 11 and a discharge port 12. The feed port 11 is used to put asphalt and emulsifier solution into the shell 10. The discharge port 12 is located at the bottom of the shell 10 and is used to discharge the mixed asphalt. The bottom of the shell 10 is also provided with a supporting foot 14 to support the shell 10; the stirring structure 20 includes a main stirring roller 21 and two pairs of stirring rollers 22. The main stirring roller A connecting plate 30 is provided on 21, the two pairs of stirring rollers 22 are installed on the connecting plate 30 and can rotate on the connecting plate 30, the main stirring roller 21 is provided with a first transmission wheel 40, the two pairs of stirring rollers 22 are respectively provided with second transmission wheels 41, the first transmission wheel 40 is respectively meshed with the second transmission wheels 41 on both sides, the main stirring roller 21 is provided with a plurality of first stirring blades 23, the two pairs of stirring rollers 22 are respectively provided with a plurality of second stirring blades 24, and the first stirring blades 23 and the second stirring blades 24 are staggered.

[0027] In this embodiment, a driving member 50 is provided on the shell 10, and the driving member 50 is connected to the main stirring roller 21. The driving member 50 can be a stepping motor, which can drive the main stirring roller 21 to rotate; the first transmission wheel 40 and the second transmission wheel 41 are both gears. Through gear transmission, the main stirring roller 21 can drive the auxiliary stirring rollers 22 on both sides to rotate, and asphalt and emulsifier solution are put into the feed port 11. The main stirring roller 21 and the auxiliary stirring roller 22 mix and stir the asphalt and emulsifier solution in each corner of the shell 10, and the stirring coverage area is large. The first stirring blades 23 and the second stirring blades 24 are staggered with each other, which can fully mix the high-viscosity rubber asphalt, and can make the asphalt and the emulsifier solution mixed more fully.

[0028] A partition plate 30 is provided in the shell 10, and the partition plate 30 divides the shell 10 into two areas. The first transmission wheel 40 and the second transmission wheel 41 are located above the partition plate 30, and the feed port 11 is located below the partition plate 30, so that the asphalt will not adhere to the first transmission wheel 40 and the second transmission wheel 41, thereby avoiding transmission being affected.

[0029] The discharge port 12 is provided with a switch valve. When the asphalt in the housing 10 is mixed with the emulsifier solution for 15 minutes, the switch valve is opened to discharge the mixed asphalt outward.

[0030] In one embodiment of the utility model, through holes 31 are respectively provided at both ends of the connecting plate 30, and the auxiliary stirring roller 22 is installed on the connecting plate 30 through the through holes 31.

The boss 27 is stuck in the annular groove 32 to play a limiting role, thereby preventing the auxiliary stirring roller 22 from falling off; it can be understood that when the driving member 50 drives the main stirring roller 21 to rotate, the first transmission wheel 40 drives the second transmission wheel 41 to rotate, so that the auxiliary stirring rollers 22 on both sides rotate, and the shell 10 is fully stirred and mixed, thereby improving the stirring efficiency.

[0031] In one embodiment of the utility model, the main stirring roller 21 and the auxiliary stirring roller 22 are respectively provided with electric heating rods 25 , and the main stirring roller 21 and the auxiliary stirring roller 22 are respectively provided with mobile power supplies 26 , and the mobile power supplies 26 are electrically connected to the electric heating rods 25 .

[0032] In this embodiment, the electric heating rod 25 and the mobile power supply 26 are both existing technologies and will not be elaborated on herein. The opening and closing of the electric heating rod 25 is controlled by a PLC circuit board. While the main stirring roller 21 and the auxiliary stirring roller 22 are stirring the asphalt, the electric heating rod 25 heats and keeps the asphalt warm to prevent the asphalt from condensing and affecting the mixing.

[0033] Working principle: asphalt and emulsifier solution are poured into the shell 10 from the feed port 11, the driving member 50 is started to drive the main stirring roller 21 to rotate, and the auxiliary stirring roller 22 rotates with the cooperation of the first transmission wheel 40 and the second transmission wheel 41 to fully stir and mix the asphalt in the shell 10. The first stirring blade 23 and the second stirring blade 24 are staggered with each other, which can fully mix the high-viscosity rubber asphalt. While stirring, the electric heating rod 25 heats the asphalt, which can make the asphalt and the emulsifier solution mixed more fully. After the stirring and mixing is completed, the switch valve at the discharge port 12 is opened to discharge the mixed asphalt outward.
