The invention relates to the technical field of organic fertilizers, in particular to an automatic proportioning and uniform mixing device for biological organic fish
guano production, which comprises a rack and a shell, the rack is composed of a bottom plate and a support and is used as an
assembly carrier of the uniform mixing device, and the top of the rack is fixedly provided with the shell. A material
barrel is loaded through a transportation plate trailer and then transported to the position between the shell and a bottom plate of the
machine frame, and the matched fish
guano raw materials are evenly mixed; and the fixing ring is fixedly arranged at the top of the shell. According to the invention, the annular weighing sensor and the quantitative tank are matched with the
electromagnetic valve for use, so that each fish
guano ingredient can be accurately added according to a preset proportion, errors caused by manual adding operation are avoided,
fermentation liquor with relatively
high activity is proportioned in the primary
fermentation tank in advance, and then the
fermentation liquor is matched with other raw materials and added into a charging basket for proportioning, so that the production efficiency is improved. The extra fermentation time during fish guano proportioning is shortened, and the consistency and efficiency of fish guano proportioning are improved.
