[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Basic screening equipment cannot combine the functions of vibration sorting and displacement sorting. A single screening method is generally inefficient for processing crushed scrap steel tailings and requires a relatively long time to complete the screening operation, which has certain limitations.

[0024] As a preferred embodiment of this utility model, such as Figures 1-5 As shown, this embodiment provides a screening device for crushing scrap steel tailings, including a support platform 1. A fixed plate 6 is welded to the rear side of the top of the support platform 1. A drive assembly 5 is installed on the surface of the fixed plate 6. The drive assembly 5 includes an auxiliary motor 501, a second gear 503, and a displacement frame 505. A first gear 502 is fixedly connected to the output end of the auxiliary motor 501. By setting the first gear 502 and the second gear 503, a meshing transmission function can be achieved. Under the drive of the auxiliary motor 501, the second gear 503 is decelerated and rotates. A movable rod 504 is movably installed on the rear side of the second gear 503. A connecting plate 506 is fixedly connected to the front side of the displacement frame 505. A protrusion 507 is fixedly connected to the bottom of the front surface of the connecting plate 506. A discharge chute 3 is provided through the top of the support platform 1. By setting the discharge chute 3, the material falling space requirement can be met. A vibration sorting device is provided on the top of the support platform 1. Component 2, the vibration sorting component 2 includes a frame 201. A screening screen 202 is fixedly embedded in the bottom of the inner cavity of the frame 201. By setting the screening screen 202, the materials inside the frame 201 can be sorted. Vibration motors 205 are bolted to the left and right sides of the bottom of the frame 201. Guide wheels 204 are set at the four corners of the bottom of the frame 201. By setting the guide wheels 204 and the guide grooves 4, rolling friction can be generated to facilitate the left and right displacement of the frame 201. Springs 203 and vertical rods 206 are respectively installed on the top of the guide wheels 204. By setting the springs 203, the frame 201 can be elastically supported and kept at the initial height position when no external force is applied. By setting the vertical rods 206, the positioning and guiding function can be used to make the guide wheels 204 move left and right with the frame 201, while preventing the springs 203 from bending.

[0025] In some embodiments, such as Figure 2 and Figure 3 As shown, the auxiliary motor 501 is bolted to the front side of the fixing plate 6, and the first gear 502 meshes with the second gear 503.

[0026] In some embodiments, such as Figure 2 and Figure 3 As shown, a positioning rod is installed through the center of the surface of the second gear 503, and the front end of the positioning rod is movably connected to the surface of the fixed plate 6.

[0027] In some embodiments, such as Figure 2 and Figure 3 As shown, a protruding rod is fixedly connected to the rear side of the second gear 503, and the right end of the movable rod 504 is movably mounted on the protruding rod, which is eccentrically positioned.

[0028] In some embodiments, such as Figure 2 and Figure 3 As shown, the left end of the movable rod 504 is movably connected to the displacement frame 505. The top of the surface of the fixed plate 6 is provided with a displacement groove 7 that works with the displacement frame 505. By setting the displacement frame 505 and the displacement groove 7, the positioning and guiding functions can be achieved, thereby ensuring the stability of the movement of the displacement frame 505.

[0029] In some embodiments, such as Figure 4 and Figure 5 As shown, the protrusion 507 is T-shaped, and a T-shaped groove 508 is provided on the rear side of the frame 201 to cooperate with the protrusion 507. By setting the protrusion 507 and the T-shaped groove 508, the anti-detachment guide function can be played, which can ensure the stability of the frame 201 in vertical displacement. When the connecting plate 506 moves left and right, the frame 201 will also move left and right.

[0030] In some embodiments, such as Figure 1 and Figure 5 As shown, the surface of the vertical rod 206 slides in contact with the connection between it and the frame 201, and a guide groove 4 is provided on the top of the support platform 1.

[0031] In some embodiments, such as Figure 1 and Figure 5 As shown, the top end of the spring 203 is fixedly connected to the bottom of the frame 201, and the bottom end of the spring 203 is fixedly connected to the connection point of the guide wheel 204.

[0032] In other embodiments, the guide wheel 204 includes an auxiliary frame and a traveling wheel, the traveling wheel being movably mounted on the auxiliary frame and adapted to the guide groove 4, and the bottom of the vertical rod 206 being fixedly connected to the top of the auxiliary frame.

[0033] In use, all components are in their initial installation state. First, a suitable amount of crushed scrap steel tailings is poured into the frame 201. Then, the auxiliary motor 501 and the vibration motor 205 are controlled to work. The auxiliary motor 501 drives the first gear 502 to rotate. Under the meshing transmission of the second gear 503, the position of the right end of the movable rod 504 can be changed. With the guidance of the displacement groove 7, the displacement frame 505 can repeatedly move left and right in the displacement groove 7. The connecting plate 506 moves synchronously. With the cooperation of the protrusion 507 and the T-slot 508, the vibration sorting component 2 will also move left and right, and complete the displacement screening operation with the screening screen 202. The operation of the vibration motor 205 makes the frame 201 vibrate up and down continuously. With the cooperation of the protrusion 507 and the T-slot 508, the stability of the frame 201 is ensured. The spring 203 is compressed or stretched, and completes the vibration screening operation with the screening screen 202. The overall efficiency is higher and more in line with the actual use requirements.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
