s3, when the screening and filtering hopper (9) swings back and forth, the lifting and contracting piece (7) is matched with the pushing piece (8), and the pushing rod (24) pushes the guide plate (23), so that the telescopic rod (20) horizontally stretches along the connecting sleeve (19) to generate a shaking effect;
s4, the material turning piece acts simultaneously, the screening hopper (9) swings back and forth, the material turning plate (29) is static, the purposes of dispersing and turning are achieved, and small-volume sand falls into the screening hopper (9) below;
s5, screening the sand and stone layer by layer through a plurality of screening hoppers (9), and enabling the finest sand and stone to fall into a receiving hopper (5);
s6, after the screen is filtered, the screen filtering hopper (9) needs to be maintained, the bar-shaped rod (32) is rotated until the bar-shaped rod is opposite to the through groove (31), the second elastic resetting piece (35) is pulled, the clamping rod (34) is withdrawn from the through groove (31), and the screen filtering hopper (9) is separated from the installation frame (6).
