The utility model provides a large-yield and high-screening-precision white rice classifying screen which comprises a box body, an impurity-removing and material-uniformizing screening assembly, a special rice screening assembly, a common rice screening assembly, a large and small broken rice screening assembly and a small broken rice screening assembly. The special rice screening assembly comprises at least two layers of screening plates which are sequentially arranged at intervals from top to bottom in the vertical direction. A dripping plate is arranged below each sieve plate, and a feeding port of each sieve plate in the special rice screening assembly is communicated with a discharging port of the dripping plate of the impurity-removing and material-uniformizing screening assembly at the upper stage through a material distributing device at the same time, so that parallel screening of the white rice is achieved; an oversize product outlet of each sieve plate in the special rice screening assembly communi
