The magnetic frame body 16 of different sizes can be replaced according to the size of the sieve plate 21, and it can be sheared to make it compatible with the sieve plate 21.

[0027] A screening device, such as Figure 1-4 As shown, it includes a screening component and a mesh magnetic frame as described above, the screening component includes a screening bin 1, the inner wall of the screening bin 1 is provided with a support frame 20, the support frame 20 is provided with multiple groups, respectively fixed to the inner walls on both sides of the screening bin 1, a spring 18 is provided on the top of the support frame 20, a fixing frame 15 is provided on the top of the spring 18, the fixing frame 15 is provided with a mounting groove, a mounting block 17 can be slidably installed through the mounting groove, a sieve plate 21 is provided on one side of the mounting block 17, the sieve plate 21 is evenly provided with multiple groups of sieve holes, the magnetic frame body 16 is detachably provided on the top of the sieve plate 21, multiple groups of vibrators 19 are provided on the bottom outer wall of the fixing frame 15, a feeding pipe 4 is connected to the top of the screening bin 1, and a collecting component for collecting screened materials and a cleaning component for cleaning the screening component are provided on one side of the screening bin 1;

[0028] When in use, the processed material is poured into the screening bin 1 through the feeding pipe 4, and the material is screened through the screen plate 21. Qualified materials that meet the size fall through the screen holes and enter the collecting component for collection. Unqualified materials can be cleaned after the cleaning component is turned on. The vibrator 19 can be started to drive the screen plate 21 to vibrate, and the unqualified materials can be shaken out of the screen holes to avoid the unqualified materials blocking the screen holes. The screen plate 21 can be removed from the fixing frame 15 as needed, and the screen plate 21 with different sizes and shapes of screen holes can be replaced;

[0029] The collecting assembly includes a collecting bin 13, which is matched with the screening bin 1. A set of pull-out racks 9 are respectively installed on the outer walls on both sides of the collecting bin 13. The inner walls on both sides of the screening bin 1 are provided with fixed grooves, in which the pull-out racks 9 can be slidably installed. A handle is provided on one side of the collecting bin 13.

[0030] When in use, the collection bin 13 is installed by installing the pull-out frame 9 in the fixed groove. After the installation is completed, the collection bin 13 is located below the sieve plate 21, and the qualified materials after screening fall into the collection bin 13 for accumulation. When a large amount of materials are accumulated, the collection bin 13 is pulled out by holding the handle to collect the materials.

[0035] In order to facilitate the addition of materials, such as Figure 1 , 2 As shown, an auxiliary frame 5 is installed at the top of the feeding pipe 4, and the auxiliary frame 5 is funnel-shaped, and the opening gradually expands upward;

[0036] During use, when adding materials to be screened, the materials are added into the device for screening through the auxiliary frame 5 whose funnel-shaped opening gradually expands upwards. The auxiliary frame 5 can effectively prevent the leakage of materials when adding materials, which causes waste.

[0037] In order to observe the amount of material collected, e.g. Figure 1 As shown, an observation window 12 is provided on one side of the collection bin 13, and the observation window 12 is made of a transparent material;

[0038] When in use, the collection bin 13 can be observed through the transparent observation window 12.
