The barrel cover 9 and the cross bar 6 are arranged. A connecting rod 11 is arranged between the rods 6, and a plurality of connecting rods 11 are arranged. The connecting rod 11 is used to fix the barrel cover 9. A first motor 12 is arranged on the barrel cover 9. The first motor 12 drives and connects the stirring mechanism 3. The stirring mechanism 3 is arranged inside the rotating barrel 2. The driving mechanism 4 is installed on the side plate 7. The driving mechanism 4 drives the rotating barrel 2 to rotate, and the rotation direction is opposite to the stirring direction of the stirring mechanism 3. A plurality of first stirring rods 13 are arranged on the inner wall of the rotating barrel 2, and a discharge pipe 14 is arranged at the bottom of the rotating barrel 2.

By controlling the stirring direction of the stirring mechanism 3 to be opposite to the rotation direction of the rotary barrel 2, the uniformity and mixing efficiency of the material mixing are further improved. After the material mixing is completed, it is discharged through the discharge pipe 14.

[0034] In this embodiment, the stirring mechanism 3 includes a rotating rod 15 and a plurality of second stirring rods 16. One end of the rotating rod 15 is connected to the first motor 12, and the other end of the rotating rod 15 passes through the barrel cover 9 and extends to the interior of the rotating barrel 2. The second stirring rods 16 are arranged on the rotating rod 15.
