The utility model discloses a screeding plate of a paver, which includes a screeding plate body (1), a polarization block (2), a polarization block revolving shaft (21), and a polarization cavity (3), wherein the polarization cavity (3) is arranged at the center of the screeding plate body (1), the polarization block (2) is arranged inside the polarization cavity (3), and the polarization block revolving shaft (21) is perpendicularly arranged. The screeding plate changes the original construction technology with which the screeding plate of the paver can only jolt vertically for compaction, meets the requirement of construction technology including horizontal vibrating and kneading on cement concrete surface, and enables the surface to be smoother and evener through processing.
