Due to the opening of the first slide groove 10, the support plate 6 can slide up and down, and the height of the mixing barrel 7 can be adjusted through the first slide groove 10. The user can directly use the telescopic cylinder 5 to adjust the height of the mixing barrel 7. When the height of the mixing barrel 7 is low, the stirring roller 13 will also be disengaged from the inner side of the connecting shaft 94, and the top plate 91 can be rotated at the top of the back plate 3 through the rotating shaft 8, so that the barrel cover 92 can be opened easily, which is convenient for the user's operation. Due to the opening of the second slide groove 16, it is convenient for the scraper 17 to slide on the inner wall of the mixing barrel 7. The rotation of the stirring roller 13 will also drive the support rod 15 and the scraper 17 to rotate. The scraper 17 can scrape the material adhered to the inner wall of the mixing barrel 7 to the inner bottom end of the mixing barrel 7, thereby avoiding waste while processing the material on the inner wall of the mixing barrel 7. When unloading is needed, the user can open the clamped sealing plate 18. After the sealing plate 18 is opened, the material will flow out through the bottom end of the mixing barrel 7. At the same time, due to the opening of the circular hole 19, the user can put the collecting bucket into the inner side of the circular hole 19 in advance, which is convenient for receiving the material.
