When the eccentric wheel 21 is no longer squeezing the moving frame 5, the moving frame 5 is reset by the elastic force of the reset spring 13, so that the moving frame 5 and the filter screen 6 swing back and forth, so as to facilitate screening, so as to facilitate screening of the crushed aggregate, so as to prevent the incompletely crushed aggregate from being mixed with the crushed aggregate, and improve the aggregate screening effect.

[0028] A discharge port is provided on one side of the moving frame 5 , and a sealing plate is slidably connected inside the moving frame 5 .

[0029] The sealing plate is pulled to open the discharge port, so that the aggregates blocked in the moving frame 5 can be cleared out, thereby facilitating the removal of the aggregates from the moving frame 5 .
