The invention discloses a rotary type anti-blocking device for a raw coal bunker, and relates to a coal hopper of a bunker in the field of electric power, metallurgy, building, coal mines, chemical engineering, petrochemical engineering, coking and the like, in particular to the rotary type anti-blocking device for the raw coal bunker. The rotary type anti-blocking device for the raw coal bunker has the advantages of being simple in structure, low in cost, high in automation degree and capable of improving working efficiency. The raw coal bunker sequentially comprises an upper bunker body, anupper transition bunker body, a rotary hopper bunker body, a lower transition bunker body and a lower bunker body from top to bottom, wherein the upper bunker body and the upper transition bunker bodyare connected through a flange plate, the lower transition bunker body and the lower bunker body are connected through a flange plate, and the rotary hopper bunker body is movably connected between the upper transition bunker body and the lower transition bunker body in a rotating mode. According to the rotary type anti-blocking device for the raw coal bunker, the manual maintenance cost can be reduced, manual beating is not needed after installation, and the labor cost is saved; the safety production is guaranteed, the potential risks of manual beating and pulling out coal by entering the raw coal bunker can be avoided; and the energy-saving benefit is very remarkable.
