[0002] The process of separating the broken material into different particle sizes through one or more layers of screen surface is called screening. The screening machine is a vibrating screening mechanical equipment that separates sand, gravel, crushed stone and other materials into different grades according to particle size by using the relative movement of the granular material and the screen surface. The screening process of the screening machine is generally continuous.

[0040] The rotating rod 601 is rotatably installed on the outer wall of the fixed ring plate 2 and penetrates through the first screen 4 and the second screen 5, and is used for providing a rotating force for the rotation of the second screen 5.

[0041] The first movable rod 602, the second movable rod 603 and the third movable rod 604 are axially slidably installed on the outer wall of the fixed ring plate 2 and located inside the first screen 4 and the second screen 5, and the first movable rod 602, the second movable rod 603 and the third movable rod 604 respectively control the rotation of the second screen 5 at different positions.

[0042] The block 607 is fixed on the outer wall of the first movable rod 602, and is used for transmitting a pressing force for the rotation of the gear 606.

[0043] The limiting unit comprises a rack 605 and a gear 606.

[0044] The rack 605 is fixed on the outer wall of the first screen 4 and is engaged with the outer wall of the gear 606, and is used for transmitting a rotating force for the rotation of the second screen 5.

[0045] The gear 606 is rotatably installed in the inner cavity of the first screen 4, and has the same rotating axis as the second movable rod 603.

[0046] The limiting mechanism 7 comprises a fixed block 701, a positioning rod 702, a movable block 703, a spring 704 and a rotating ring 705.

[0047] The fixed block 701 is fixed on the outer wall of the rotating rod 601, and is used for guiding the movement of the positioning rod 702;

[0048] The positioning rod 702 is fixed on one end of the first movable rod 602, and is used for driving the movable block 703 to move synchronously;
