A first sleeve 16 is fixed to the outer wall of one side of the slide 12 by bolts, and the first round rod 15 is slidably connected inside the first sleeve 16. A round table 17 and a limit block are fixed to the outer side of the first round rod 15 by bolts. A second spring 18 is sleeved on the outer side of the first round rod 15, and the two ends of the second spring 18 are respectively fixed to the limit block and the first sleeve 16. A limit assembly is provided on one side of the first sleeve 16 to push the first round rod 15 to drive the first screen 13 to move along the second screen 14. At this time, the sieve holes on the first screen 13 and the sieve holes on the second screen 14 are staggered, so that the connected feed aperture becomes smaller, and the second spring 18 contracts at the same time. Then, the limit assembly is used to limit the position of the round table 17, so that the position of the first screen 13 after movement is limited and fixed.

[0025] In the present invention, it should be noted that the toggle assembly includes a fixing frame 9, which is fixed to an outer wall of one side of the shell 1 by bolts, a motor is fixed to one side of the fixing frame 9 by bolts, a gear 3 is keyed to one end of the motor output shaft, and the gear 3 is in contact with the slide bar 4, sliders 5 are fixed to the outer walls of both sides of the slide 12 by bolts, two first slide grooves 6 are provided on both sides of the shell 1, and the slider 5 is slidably connected to the first slide groove 6, a first spring 7 is welded to the top of the slider 5, and the first spring 7 is fixed to the first slide groove 6, the motor rotates to rotate the gear 3, so that it toggles the slide bar 4 to move up and down along the second slide groove 8, and at the same time, the slider 5 moves up and down along the first slide groove 6 with the cooperation of the first spring 7, so that the slide 12 can move up and down to generate vibration, the limiting assembly includes a second slide sleeve 19, the second slide sleeve 19 is fixed to one side of the first slide sleeve 16, the second slide sleeve 19 is slidably connected to the second round rod 20, and The second round rod 20 is in contact with the truncated cone 17, and a third spring 21 is sleeved on the outer side of the second round rod 20, and the two ends of the third spring 21 are respectively fixed to the second sleeve 19 and the second round rod 20. The truncated cone 17 moves and squeezes the second round rod 20, so that the second round rod 20 moves outward along the second sleeve 19, and the third spring 21 contracts until the truncated cone 17 moves to the other side of the second round rod 20. At this time, the second round rod 20 loses its restriction, and the third spring 21 rebounds and stretches, so that the second round rod 20 is reset. At this time, the second round rod 20 limits the position of the truncated cone 17, and a avoidance groove 2 is provided on one side of the shell 1, and the first sleeve 16 passes through the avoidance groove 2. A feeding port 10 is provided on one side of the shell 1. The staff removes large particles of iron tailings sand from the second screen 14 through the feeding port 10. The first screen 13 is connected to the second screen 14. A connecting port is provided at the bottom of the shell 1, and a feeding hopper 11 is fixed in the connecting port by bolts.

[0026] Working principle: When it is necessary to screen iron tailings sand particles, first pour the iron tailings sand particles into the housing 1, so that the second screen 14 and the first screen 13 screen the materials. The iron tailings sand particles with larger particles remain on the upper surface of the second screen 14. The staff removes the large-particle iron tailings sand particles through the feeding port 10. At the same time, the smaller iron tailings sand particles fall downward through the screen holes of the first screen 14 and the second screen 13 and are discharged through the feeding hopper 11. When it is necessary to reduce the size of the screen holes communicating between the two screens, push the first round rod 15 to drive the first screen 13 to move along the second screen 14. At this time, the screen holes on the first screen 13 and the screen holes on the second screen 14 are staggered, reducing the aperture of the discharged material. At the same time, the second spring 18 contracts, the frustum 17 moves and squeezes the second round rod 20, causing the second round rod 20 to move outward along the second sliding sleeve 19, and the third spring 21 contracts until the frustum 17 moves to the other side of the second round rod 20. At this time, the second round rod 20 loses its restriction, and the third spring 21 rebounds and elongates, causing the second round rod 20 to reset. At this time, the second round rod 20 restricts the position of the frustum 17.

For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there is internal communication between two devices, components, or parts. Those of ordinary skill in the art can understand the specific meanings of the above terms in this application according to specific circumstances.
