The utility model discloses a dry-method particle size grading reduction device for soil. The dry-method particle size grading reduction device comprises a supporting platform, the at least three cyclones are uniformly distributed and fixedly arranged on the supporting platform in a surrounding manner by taking the vertical pipe as a center, and the vertical pipe is connected with a plurality of feeding branch pipes so as to be communicated with feeding holes of the cyclones; the first material collecting box is used for collecting first particles classified by the hydrocyclone, and the second material collecting box is used for collecting second particles classified by the hydrocyclone. According to the particle size grading reduction device for the soil through the dry method, the adverse problems caused by vibration are effectively reduced through reasonable position arrangement of the multiple hydrocyclones, meanwhile, the multiple hydrocyclones are integrated in the supporting platform, the same first ma
