This utility model relates to the field of cement cover plate processing technology and discloses a quantitative feeding device for cement cover plate casting, including a feeding cylinder. A stirring device is installed inside the feeding cylinder, and a support frame is fixedly installed on the outer wall of the feeding cylinder. A discharge pipe is fixedly installed at the bottom of the feeding cylinder.
