Meanwhile, the arrangement angle is limited by the environment, and the small-granularity materials and the included soil are screened out in the conveying process. The utility model solves the problems better through various designs of the mechanism. Measures relating to low resistance: 1) the press plates are respectively arranged on the inner sides of the racks on the two sides, the roller slots are formed below the two ends of the rack plate, and the carrier rollers are arranged at the corresponding positions on the two inner sides of the racks, so that the rack plate can reciprocate under the support of the carrier rollers. The gravity of the heavy rack plate is borne by the carrier roller arranged on the rack, so that the transmission between the rack plate and the gear shaft is easy, and the resistance is greatly reduced. 2) The chain connection mode is that two adjacent parts are connected in sequence and adjacently by using a chain, so that the transmission is more reliable and the resistance is low. 3) An overrunning clutch is arranged between the roller sleeve and the roller shaft, the roller sleeve does not rotate when the roller shaft rotates reversely, and the overrunning clutch plays a role in reducing resistance. Because the roller-type screening machine is arranged at intervals in a roller-type mode, a gap is reserved between two adjacent rollers, small-granularity materials and included soil can be screened out in the conveying process, and meanwhile, the structure can meet the requirement of conveying the materials within the angle range of minus 10 degrees to plus 23 degrees.
