[0030] The scraper 4 is fitted with the inner wall of the mixing cylinder 1, so as to scrape off the material adhering to the inner wall of the mixing cylinder 1 and enhance the mixing effect.

[0031] like Figure 4 and Figure 5 As shown, the flushing assembly includes a water outlet hole 18 opened on the side wall of the stirring shaft 14, the water outlet hole 18 is connected to the inner cavity of the stirring shaft 14, the side wall of the water outlet hole 18 is fixedly connected to a limit plate 29, and the side wall of the water outlet hole 18 is located outside the limit plate 29. Two baffles 19 are arranged on the side wall of the water outlet hole 18, and the side walls of the baffles 19 are fixedly connected to a circular shaft 20. The other end of the circular shaft 20 is rotatably connected to the side wall of the water outlet hole 18, and the side wall of the circular shaft 20 is equipped with a torsion spring 21.

[0032] Furthermore, the cross-sectional shape of the water outlet 18 is stepped, so that the baffle 19 can be hidden in the water outlet 18, and the baffle 19 is limited by the limiting plate 29 to prevent the baffle 19 from entering the stirring shaft 14 due to the impact force of the material during the stirring process.
