Organic fertilizer production and processing equipment easy for microbial fermentation

The invention discloses organic fertilizer production and processing equipment easy for microbial fermentation, which comprises a fermentation tank used for microbial fermentation of fertilizer raw materials; the air inlet structure is used for inputting fresh air into the fermentation tank; the multi-layer reciprocating screening structure is arranged in the fermentation tank and is used for bearing fertilizer raw materials and reciprocating screening of the raw materials, so that the raw materials are in full contact with oxygen in the screening process, and aerobic fermentation of the raw materials is facilitated; the multi-layer reciprocating screening structure comprises a plurality of single-layer filter screens which are distributed up and down, and the single-layer filter screen on the uppermost layer can move to the lowermost layer after raw materials are screened, so that the raw material bearing capacity of the multi-layer reciprocating screening structure is guaranteed, and fertilizer raw material
