Compound microbial solid inoculant seed dressing and uniform mixing machine

The invention relates to the technical field of mixing and wall breaking of microbial agents, in particular to a compound microbial solid microbial agent seed dressing and uniform mixing machine which is characterized in that a middle floating plate is provided with a plurality of groups of positioning rings eccentrically corresponding to a fine filter screen, extrusion bags are arranged in the positioning rings, and an air bag attached to the outer wall of the lower end of each extrusion bag and the lower end face of the middle floating plate is arranged in an upper insertion layer; the device has the beneficial effects that by arranging the overturning plate with air bag protection, when the grinding roller extrudes and breaks walls, a granular microbial agent is separated and broken by the coarse filter screen and falls into the middle floating plate, when the grinding roller extrudes the middle floating plate, one-way extrusion buffering is achieved through the air bag, and excessively extruded microbial
