The screening process of the screening machine is generally continuous. After the screened raw materials are fed to the screening device, the raw materials smaller than the size of the screen plate holes pass through the screen, thereby screening out materials of different particle sizes;

[0014] The present invention has the following beneficial effects:
[0015] 1. The present invention completes the screening of gravel with different particle sizes through the combination of screening annular nets in the screening box. The screening box is rotating. Under the action of centrifugal force, the gravel passes through the first screening annular net, the second screening annular net and the third screening annular net with different mesh diameters from the first screening chamber in sequence to enter the second screening chamber, the third screening chamber and the fourth screening chamber. The centrifugal force is used to quickly distinguish the gravel with different particle sizes. After the gravel enters and stays in different screening chambers, the fine sand on the surface of the gravel is sucked and stored in the recovery bin by a sand suction machine connected to the conveying component. By screening gravel with different particle sizes to facilitate the absorption of fine sand attached to the surface, the problem of difficulty in absorbing fine sand at the bottom after the accumulation of gravel with different particle sizes is avoided, thereby improving the absorption efficiency.
[0016] 2. The present invention arranges a beating rod on the outer peripheral wall of the rotating shaft to facilitate beating of the gravel in the first screening chamber to reduce the particle size of the gravel. BRIEF DESCRIPTION OF THE DRAWINGS
