Screening device for machine-made sand production

The invention provides a screening device for machine-made sand production, and relates to the technical field of screening devices.The screening device comprises a base, a set of hydraulic rods are installed on the upper surface of the base, stand columns are fixedly installed at the upper ends of the hydraulic rods, and screening assemblies used for screening machine-made sand are fixedly installed among the stand columns; a mounting frame is fixedly mounted at the upper ends of the multiple stand columns, and a material pushing assembly used for discharging screened materials is mounted in the mounting frame. A through opening is formed in one side of the frame, so that screened materials can be discharged through the through opening, in order to enable the materials to be discharged, a matched clamping plate can be matched with a protruding block, under the action of a rotating shaft, a sealing baffle opens the through opening, and then discharging operation is conducted; compared with an existing screeni
