The invention discloses a shaking-type screening and impurity filtering device for building sand. The shaking-type screening and impurity filtering device comprises a baseplate, a material accommodating cavity, a collecting box, a rotating shaft I, a rotating shaft II, a filtering mesh bag and an electric push rod, wherein a bracket is arranged at the upper end of the baseplate; the material accommodating cavity is arranged at the upper end of the bracket; an upper cover, a feeding pipe, a material guiding baseplate, a motor, a stirring shaft, a stirring blade and a material guiding pipe are arranged on the material accommodating cavity; the collecting box is arranged at the upper end of the baseplate; rotating support plates are arranged on the collecting box; the rotating shaft I is arranged in the rotating support plates; the rotating shaft II and the filtering mesh bag are arranged at the lower end of the rotating shaft I; a transmission gear is arranged on the periphery of the rotating shaft I; the electric push rod and a toothed plate are arranged at the upper end of the baseplate; universal wheels are arranged below the baseplate; a threaded rod is arranged on the baseplate;and a non-slip mat is arranged at the lower end of the threaded rod. By adoption of the shaking-type screening and impurity filtering device disclosed by the invention, metal impurities in yellow sand can be filtered out; the uniform and stable discharging operation can be achieved; and besides, the yellow sand can be stably and efficiently screened in a shaking manner.
