Preferably, the peripheral surface of the sawdust screening roller 2 is provided with a material poking frustum 22, and the wood blocks are promoted to move more effectively through the active material poking effect. The conical arrangement of the material shifting frustum 22 can avoid forming obvious grooves between the material shifting frustum 22, so that wood blocks are easily prevented from being jammed, and wood dust accumulation can be reduced. Preferably, the material-shifting frustum 22 is provided with material-shifting side surfaces 23 inclined to two sides of the material advancing direction. The material stirring side surface 23 is arranged to apply component forces to the wood blocks towards two sides of the advancing direction while the material stirring advances, so that the wood blocks can move laterally while advancing, the wood blocks can be quickly paved and can move out of order, wood chips among the wood blocks can be more easily separated from the wood blocks to be screened out in the process, and no dead angle exists in the screening out of the wood chips. For the present embodiment to provide the material ejecting side surface 23, the cross section of the material ejecting conical table 22 is preferably set to be diamond-shaped or approximately diamond-shaped, so that the material ejecting conical table 22 can form staggered arrangement in both the circumferential direction and the axial direction of the outer circumferential surface of the sawdust screening roller 2, and thus the sawdust screening roller 2 is more easily covered with the sawdust screening material, and a good sawdust screening effect of the sawdust screening roller 2 is ensured.
