Anti-hardening coating and packaging integrated device for microbial compound fertilizer

The utility model discloses an anti-hardening coating and packaging integrated device for a microbial compound fertilizer. The anti-hardening coating and packaging integrated device comprises a semi-finished product fertilizer bin, a first belt conveyor, a first discharging chute, a medicament adding unit, a coating machine, a second discharging chute, a cooling machine, a third discharging chute and a packaging machine. The method has the advantages that by adding the anti-hardening agent, hardening of the fertilizer can be effectively avoided; steam is introduced into the heat exchange jacket to heat the agent tank, so that the anti-hardening agent and the coating agent are fully mixed; by introducing air into the gas-liquid mixer, under the action of air flow, the mixed medicament is fed into the coating machine, and under the action of the air flow, the mixed medicament can be sprayed onto a semi-finished fertilizer in the coating machine in an atomized form, so that uniform contact between the mixed medi
