Base material premixing machine for producing biopolymer organic fertilizer

The utility model belongs to the technical field of organic fertilizer production, and particularly relates to a base material pre-mixing machine for biopolymer organic fertilizer production, which comprises a pre-mixing barrel, a feed port is formed in the middle of the upper end of the pre-mixing barrel, a discharge port is formed in the middle of the lower end of the pre-mixing barrel, a base is arranged at the lower end of the pre-mixing barrel, the base is L-shaped, and the feed port is communicated with the discharge port. A supporting rod is fixedly connected to the upper end of one side of the base, the outer surface of the supporting rod is sleeved with a rotating shaft, and a transmission shaft is arranged at the axis in the premixing barrel; the scraping plate and the brush continuously rotate along the inner wall, so that a base material adhered to the inner wall of the material mixing barrel can be scraped off, and the stirring process is smoother; the contact distance between the scraping plate
