NOVELTY - A device comprises: sorting machine (1) for removing the sandy soil and garbage in the city garbage, crusher (2) for crushing the sorted garbage, winnowing machine (3) for keeping the organics and removing other crushing garbage, organic garbage fertilizer machine (4) for decomposing the reserved organics and preparing into fertilizer, stirrer (9) for mixing the organic fertilizer and inorganic fertilizer, drier (5) for drying the organic and inorganic fertilizer, and electric sieve (6) for sieving the organic and inorganic fertilizer product.    USE - For producing organic inorganic mixing fertilizer by microorganism (claimed).    ADVANTAGE - The device provides easy raw material acquisition, low manufacturing cost and no pollution. The device easily collect the material, has low manufacturing cost, greatly improves the processing and use of the ability of city garbage, reduces the pollution and beautify the environment. The produced fertilizer can improve soil structure and kill the harmful bacteria in soil, decomposing the high concentration chemical composition in the soil so as to avoid the soil from hardening; promotes the growth of crop and improves crop quality.    DETAILED DESCRIPTION - A device comprises: sorting machine (1) for removing the sandy soil and garbage in the city garbage, crusher (2) for crushing the sorted garbage, winnowing machine (3) for keeping the organics and removing other crushing garbage, organic garbage fertilizer machine (4) for decomposing the reserved organics and preparing into fertilizer, stirrer (9) for mixing the organic fertilizer and inorganic fertilizer, drier (5) for drying the organic and inorganic fertilizer, and electric sieve (6) for sieving the organic and inorganic fertilizer product, where the sorting mechanism, crusher, winnowing machine, organic garbage fertilizer machine, stirrer, drier and electric sieve are connected in turn. The sorting machine is connected with the dustbin (7) for collecting sand soil and garbage. The winnowing machine is sleeved with a non-organic collecting bag (8). The stirrer is mounted with a loading machine (10) for adding inorganic fertilizer.
