The upper and lower sides of the inner wall of the mixing drum 7 are fixedly connected with two partition plates 14. The front and rear sides of the right end of the mixing drum 7 are penetrated by a discharge pipe 11, and the outer wall of the discharge pipe 11 is provided with a valve 12. The top of the mixing drum 7 is fixedly connected with an L-shaped block 8, and the front side of the bottom end of the L-shaped block 8 is fixedly connected with an electric push rod 9. The driving end of the electric push rod 9 is fixedly connected with a limit block 15, and the outer wall of the limit block 15 is slidably connected to the inner wall of the mixing drum 7.

[0024] Embodiment 1: The slurry is respectively injected into the two cavities separated by the partition 13 in the material box 1 through the two feed ports 2, and the fan 4 is started to pressurize the air conveyed into the cavity through the air duct 3 so that the slurry can flow out from the connecting pipe 5. When it is necessary to convey two mixed slurries, the two valves 6 are opened to convey the slurry to the inside of the mixing barrel 7 through the connecting pipe 5, and then the electric push rod 9 is started to pull the limit block 15 from the mixing barrel 7 to release the limit on the stirring plate 16, and then the motor 10 is started to drive the rotating shaft 17 to rotate so that the stirring plate 16 rotates inside the mixing barrel 7, so that the cavities separated by the partition 14 and the stirring plate 16 inside the mixing barrel 7 are interconnected, so that the two slurries are mixed and stirred by the stirring plate 16 to make the mixing more sufficient, and at the same time, the opening degree of the two valves 6 can be controlled respectively to control the slurry mixing ratio, and the mixed slurry is discharged along the discharge pipe 11 by opening the valve 2 12.

Stirring is performed to make the mixing more complete. At the same time, the opening degree of the two valves 6 can be controlled separately to control the mixing ratio of the slurry. The mixed slurry is discharged along the discharge pipe 11 by opening the valve 2 12. When the two slurries are transported separately, the speed of the motor 10 is first reduced to make the stirring plate 16 rotate slowly inside the mixing barrel 7, and then the electric push rod 9 is controlled to push the limit block 15 back into the mixing barrel 7 to jam the stirring plate 16, and then the motor 10 is turned off.
