[0024] In the above structure, by setting the upper screen plate 3 and the lower screen plate 4 in the inner cavity of the equipment body 1, when it is necessary to screen steel raw materials, the material is put into the inner cavity of the equipment body 1 through the feeding bin 2. Then, under the action of the upper screen plate 3 and the lower screen plate 4, the steel raw materials can be screened. Moreover, the angle of the upper screen plate 3 and the lower screen plate 4 can be adjusted according to different screening effects, so as to better filter different steel raw materials.

[0025] In a preferred embodiment, the outer wall of the lifting seat 6 is rotatably connected to the outer wall of the lower screen plate 4, and the outer wall of the fixing screw 7 passes through the inner cavity of the lifting seat 6.

[0026] In the above structure, a lifting seat 6 is provided on the outer wall of the equipment body 1, and the outer wall of the lifting seat 6 is rotatably connected to the outer walls of the upper screen plate 3 and the lower screen plate 4. By adjusting the height of the lifting seat 6, the support angle between the upper screen plate 3 and the lower screen plate 4 is changed under the action of the lifting seat 6, thereby realizing the change of the support angle between the upper screen plate 3 and the lower screen plate 4, so as to facilitate the screening of different steel materials.

[0027] In a preferred embodiment, there are two lifting seats 6, and the two lifting seats 6 are respectively installed on the outer walls of the two sides of the equipment body 1.

[0028] In the above structure, by setting the lifting seat 6 on the outer wall of the upper screen plate 3 and the lower screen plate 4, the angle between the upper screen plate 3 and the lower screen plate 4 and the inner wall of the equipment body 1 can be changed by changing the height of the lifting seat 6, thereby better realizing the screening of materials and achieving the screening effect for different steel materials.

[0029] In a preferred embodiment: the top of the adjusting nut 8 contacts the outer wall of the lifting seat 6, and the outer walls of the upper screen plate 3 and the lower screen plate 4 pass through the inner cavity of the movable groove 5 and are rotatably connected to the outer wall of the lifting seat 6.

[0030] In the above structure, by adjusting the position of the adjusting nut 8 on the outer wall of the fixed screw 7, the lifting seat 6 can be moved upward along the outer wall of the fixed screw 7 under the action of the adjusting nut 8, thereby realizing the adjustment of the installation angle of the upper screen plate 3 and the lower screen plate 4, so as to better screen different materials.

[0031] In a preferred embodiment, the outer wall of the swing plate 13 at the end away from the drive disk 15 is rotatably connected to the outer wall of the fixed plate 11, and the swing plate 13 is made of stainless steel.

[0032] In the above structure, the drive motor 14 is provided on the top of the equipment body 1, and the drive disk 15 is provided on the power output shaft of the drive motor 14. As the drive disk 15 rotates, the swing plate 13 can be pulled to reciprocate, thereby driving the fixed plate 11, so that the striking rod 12 strikes the outer wall of the upper screen plate 3 and the lower screen plate 4.

[0033] In a preferred embodiment, the outer wall of the striking rod 12 contacts the outer walls of the upper sieve plate 3 and the lower sieve plate 4 respectively, and the outer wall of the striking rod 12 passes through the inner cavity of the sliding groove 9 and contacts the outer walls of the upper sieve plate 3 and the lower sieve plate 4.

[0034] In the above structure, the striking rod 12 provided on the outer wall of the lifting plate 10 can pull the fixed plate 11 as the drive disc 15 rotates, causing the fixed plate 11 to move up and down along the outer wall of the equipment body 1, thereby driving the striking rod 12 to move up and down. Under the action of the striking rod 12, the outer walls of the upper screen plate 3 and the lower screen plate 4 can be struck, thereby removing the material stuck on the outer walls of the upper screen plate 3 and the lower screen plate 4.

[0035] In a preferred embodiment, the striking rod 12 is made of high carbon steel, and the inner cavity of the feeding bin 2 is connected to the inner cavity of the equipment body 1.

[0036] In the above structure, the striking rod 12 is provided on the outer wall of the lifting plate 10. The striking rod 12 moves with the up and down movement of the lifting plate 10, thereby striking the outer walls of the upper screen plate 3 and the lower screen plate 4 under the action of the striking rod 12, thereby vibrating and releasing the raw materials stuck on their outer walls under the action of the striking.

[0037] In a preferred embodiment: the drive motor 14 is a low-speed, high-torque motor, and the sieve holes on the outer wall of the upper sieve plate 3 are larger than the sieve holes on the outer wall of the lower sieve plate 4.

[0038] In the above structure, the upper screen plate 3 and the lower screen plate 4 are arranged in the inner cavity of the equipment body 1. Under the action of the upper screen plate 3 and the lower screen plate 4, the material can be screened better. Under the drive of the drive motor 14, the fixed plate 11 is driven, so that the striking rod 12 can strike the outer wall of the upper screen plate 3 and the lower screen plate 4 to remove the raw materials stuck on the outer wall of the upper screen plate 3 and the lower screen plate 4.

[0039] Working Principle: During operation, when steel raw materials need to be screened, the steel raw materials are fed into the inner cavity of the equipment body 1 through the feeding hopper 2. The materials are then screened by the upper screen plate 3 and the lower screen plate 4. The installation angles of the upper screen plate 3 and the lower screen plate 4 can be adjusted according to the required screening rate for different materials, resulting in a greater inclination angle. This allows the raw materials to slide more quickly off the outer walls of the upper screen plate 3 and the lower screen plate 4. By rotating the adjusting nut 8, the adjusting nut 8 moves along the outer wall of the fixing screw 7, thereby adjusting the position of the lifting seat 6 and causing it to move upwards. This allows for changes in the support angles of the upper screen plate 3 and the lower screen plate 4, enabling better screening of steel raw materials. When it is necessary to clean the debris stuck on the outer walls of the upper screen plate 3 and the lower screen plate 4, the drive motor 14 is started. Driven by the drive motor 14, the swing plate 13 swings on the outer wall of the drive disc 15 and pulls the fixed plate 11 to move up and down reciprocally. This causes the striking rod 12 to continuously strike the outer walls of the upper screen plate 3 and the lower screen plate 4, thereby clearing the debris stuck on the outer walls of the upper screen plate 3 and the lower screen plate 4 and preventing the screen holes on the outer walls of the upper screen plate 3 and the lower screen plate 4 from being blocked, thus avoiding affecting the screening of steel raw materials.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
