Then the driving motor 7 drives the vertical rod 8 to rotate, and the vertical rod 8 drives the stirring plate 10 to rotate through the cross bar 9 to stir the anti-channeling agent. After the stirring is completed, the collecting container is placed on the bottom plate 1. At this time, the anti-channeling agent is discharged from the mixing drum 4 through the discharge hole 5 below, and the cross bar 9 is pushed to make one side of the stirring plate 10 against the inner wall of the mixing drum 4. At this time, the driving motor 7 continues to drive the stirring plate 10 to rotate, and the stirring plate 10 scrapes the inner wall of the mixing drum 4 to clean the anti-channeling agent remaining on the inner wall, which is more convenient and reduces residue to avoid waste.
