Furthermore, the exhaust holes are respectively formed in two opposite sides of the branch pipe.

Furthermore, one side of the branch pipe is provided with a plurality of rows of the perforated bricks, and the air holes of the plurality of rows of the perforated bricks are communicated end to end.

The utility model has the advantages that when fermented materials such as crop straws, vinasse, livestock manure and the like are subjected to aerobic fermentation in the fermentation tank, oxygen is input into the fermented materials through the air guide pipe and the branch pipe via the exhaust holes and the vent holes of the perforated bricks aligned with the exhaust holes, so that the fermented materials are fully fermented in an oxygen-rich environment, the turning times are reduced, and the production cost is reduced. On the other hand, the temperature of oxygen in the fermented material is increased through the heating coil, so that the inside of the fermented material is rapidly maintained at the better fermentation temperature during fermentation, the temperature of the fermentation temperature is ensured, the fermentation time is shortened, and the production efficiency of the organic fertilizer is improved.
