High-sealing property stirring hopper gate plate

The invention provides a high-sealing property stirring hopper gate plate which comprises a cover body and a sealing part, wherein the sealing part is arranged inside on the inner side of the cover body; the cover body comprises a substrate and an outer surface plate; a gap between the substrate and the outer surface plate is divided into a plurality of independent cavities by a partition supportrack; the cavities are filled with buffer bodies; the sealing part is detachably mounted on the substrate through a connecting part; an auxiliary sealing ring is correspondingly arranged at a connecting hole of the sealing part; buffer grooves are formed in the sealing part in a circumferential direction; the support rack is made of an elastic material. The high-sealing property stirring hopper gate plate is simple in structure, reasonable in design, solid to mount, stable in structure and good in sealing property since the sealing part is mounted on the gate plate fixedly by using the connecting part, in addition, as
