Spherical object screening device

The utility model relates to a spherical object screening device. The spherical object screening device comprises a material pretreatment part and a material screening part, the material pretreatment part comprises a belt material roller driven by a driving motor to rotate, a plurality of material cavities are distributed on the surface of the belt material roller, and the depth and the width of the material cavities are matched with the diameter of a to-be-selected spherical object; a crushing unit close to the surface of the material carrying roller is arranged above the material carrying roller, and is used for crushing the to-be-screened material part higher than the material cavity; a discharge hole is formed in a rotating path of the belt roller after passing through the crushing unit; a material screening part is arranged below the discharging port and provided with a screen. By means of the structure, non-circular objects can be rapidly screened, the consistency of the size and the roundness of obtain
