Among them, the transmission shaft 3 is suitable for driving the adjustment component 4 to rotate circumferentially to mix and stir the material; the adjustment component 4 moves axially relative to the transmission shaft 3 to adjust the discharge speed of the material in the conveying cylinder 2. By setting the adjustment component 4, the material discharge speed in the conveying cylinder 2 can be adjusted. When the adjustment disk 43 seals the discharge port 46, the circumferential rotation of the guide blade 44 can better convey the mixed material; when the guide blade 44 abuts against the inner wall of the conveying cylinder 2, it can also scrape and clean the residual material on the inner wall of the conveying cylinder 2, thereby improving work efficiency.

[0045] Reference Figure 2, the adjustment component 4 includes: a lifting sleeve 41, whose sliding sleeve is arranged on the outer wall of the transmission shaft 3; further, a protrusion is fixed on the outer wall of the transmission shaft 3, and a groove matching the protrusion is provided on the inner wall of the lifting sleeve 41 along the axial direction, and the protrusion is suitable for vertically sliding in the groove. When the transmission shaft 3 rotates circumferentially, the lifting sleeve 41 is driven to rotate circumferentially synchronously.
