Mixing device for biofertilizer

Abstract

The invention belongs to the technical field of biofertilizer production, and discloses a mixing device for the biofertilizer. The mixing device comprises a rack provided with a vertical mixing tank; the left side of the mixing tank is rotatably connected with the rack by a connecting shaft; a rotary shaft is arranged at the right side of the mixing tank; the rotary shaft and the connecting shaft are coaxial; the rotary shaft and the rack are rotatably matched; a motor is connected with the outside end part of the rotary shaft; a cavity is arranged in the rotary shaft provided with an air vent communicated with the cavity; an air box sleeves the outer part of the rotary shaft and is rotatably matched with the rotary shaft; the air box is communicated with the air vent; a sealing ring is arranged between the air box and the rotary shaft; the air box is communicated with a blowing pipe; the rotary shaft extends into the mixing tank; a jetting box is arranged at the inside end part of the rotary shaft and is communicated with the cavity; a plurality of jet holes are formed in the left side surface of the jetting box. The mixing device for the biofertilizer solves the technical problem of a poor mixing effect caused by the fact that raw materials are easily caked during mixing of the existing biofertilizer.

Description

technical field [0001] The invention belongs to the technical field of biological fertilizer production, and in particular relates to a mixing device for biological fertilizer. Background technique [0002] Biological fertilizer is based on organic matter, and then mixed with bacterial agents and inorganic fertilizers. It can provide crop nutrition, improve the soil, and at the same time disinfect the soil, that is, use microbial decomposition to eliminate pesticides, herbicides and pollutants from products such as petrochemicals, and at the same time remediate the soil. Because biological fertilizer is non-polluting to the environment, it has been paid more and more attention, and biological fertilizer will play an important role in future agricultural production. [0003] The raw materials of bio-fertilizer usually include animal manure, domestic garbage, dead branches and rotten leaves, biogas residue, waste bacteria, etc. The production of bio-fertilizer usually include...
