The rear shaft support in the technical scheme can be composed of a rear shaft support and a rear shaft bearing, wherein the rear shaft support is of a split structure, and the rear shaft bearing is a split sliding bearing matched with the rear shaft support.

The rear crank bearing seat can be composed of a rear crank bearing and a rear crank bearing, the rear crank bearing is of a split structure, and the rear crank bearing is a split sliding bearing matched with the rear crank bearing.

The working principle of the invention is as follows: when the screening roller revolving device works, the speed reducer drives the front crank shaft to rotate through the coupler, the front crank shaft drives the screening roller to integrally rotate around the center of the speed reducer, and the rotation is the revolution of the screening roller. Meanwhile, the screening roller drives the rear crank shaft to rotate. Because the fixed gear is meshed with the moving gear and the fixed gear is fixed and does not rotate, the moving gear rotates around the axis of the moving gear. The rotation of the moving gear can make the rear shaft rotate around the axis of the rear shaft through key connection. The rear shaft is connected with the screening roller, so that the screening roller can rotate around the axis of the screening roller, namely, the screening roller can rotate. Thus, the screening drum rotates and revolves. The revolution makes the screening roller do circular vibration in the direction vertical to the axis of the screening roller, which is very beneficial to loosening and settling of materials and improves the screening efficiency of the materials.

The invention has the beneficial effects that: the screening roller of the machine does circular vibration in the direction vertical to the axis on the basis of rotation, so that loosening and sedimentation of materials are facilitated, and the screening efficiency of the materials is improved.
