Helical surface vibration reduction device for vibrated fluidized bed

The utility model discloses a helicoid vibrated fluidized bed damping device which comprises a helicoid vibrated fluidized bed body and a base, four damping air bags are evenly arranged between the helicoid vibrated fluidized bed body and the base, one end of a fixing column is fixedly connected with an installation disc, one side of each damping air bag is provided with an inflation piece, and the other side of each damping air bag is provided with a fixing column. A locking cover is arranged at the upper end of the inflation piece, and an inflation core is arranged on the inner side of the inflation piece. Through the structure, one end of the fixing column is fixedly connected with the mounting disc, so that damping can be performed between the helicoid vibrated fluidized bed machine body and the base through the damping air bag structure, and the conditions of aging, poor damping effect, serious resonance around equipment and potential safety hazards caused by long-time use are not easy to occur; the oute
