Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, specifically a vibrating feeding device. Background Technology

[0002] A vibrating screen operates by utilizing the reciprocating rotary vibration generated by a vibrator. The upper rotating weight of the vibrator causes the screen surface to produce planar rotary vibration, while the lower rotating weight causes it to produce conical rotary vibration. The combined effect of these two forces results in a complex rotary vibration of the screen surface, whose trajectory is a complex spatial curve. This curve projects as a circle on the horizontal plane and as an ellipse on the vertical plane. Adjusting the excitation force of the upper and lower rotating weights changes the amplitude, while adjusting their spatial phase angle changes the shape of the screen surface's motion trajectory and thus alters the material's movement trajectory on the screen surface.

[0003] However, after the existing iron sheets are cut or stamped, there will be some small metal fragments in the stockpile, which need to be screened. The metal powder generated during the screening of the traditional vibrating screen structure will be scattered into the surrounding air, which can easily cause damage to the respiratory tract. Therefore, the existing technology needs to be improved. Utility Model Content

The bearing seats 15 are installed in the hinge cavities. The inner wall of one side of the fixed frame 8 is provided with a limiting cavity 11. The other side wall of the vibrating screen 9 is provided with a limiting component 17. The limiting component 17 is installed in the limiting cavity 11. The outer wall of the discharge bin 3 is provided with a vibrating plate 5. The side wall of the vibrating plate 5 is provided with a vibrating spring 4. The lower end of the vibrating spring 4 is installed on the vibrating screen box 1.

[0023] In this technical solution, the material discharge bin 3 is set at an angle, with the higher part located at the top of the vibrating screen box 1 and the lower part located on the left side of the vibrating screen box 1. The recovery port 7 of the material discharge bin 3 is connected to the inside of the vibrating screen box 1. The vibrating screen 9 in the fixed frame 8 can swing within the fixed frame 8, thereby blocking the recovery port 7. The iron pieces in the feed hopper 3 fall into the vibrating screen 9, and the vibration is generated by the vibration spring 4. The debris falls through the vibrating screen 9 and the iron pieces fall into the material discharge bin 3.

[0024] In some technical solutions, the outer wall of the bearing seat 15 is provided with rotating cavities 16 evenly spaced along its axis, and ball bearings 19 are installed inside the rotating cavity 16, with the ball bearings 19 fitting against the inner wall of the hinge cavity.

[0025] In this technical solution, the rotating shaft 14 is fixed inside the shaft cylinder 12, and the shaft cylinder 12 is installed outside the vibrating screen 9 through the fixing plate 13. The rotating shaft 14 can rotate in the hinge cavity, thereby realizing the swing of the vibrating screen 9 and realizing the opening and closing of the recycling port 7. While the rotating shaft 14 rotates, the ball bearings 19 on the outer wall of the shaft seat 15 rotate successively to avoid the accumulation of impurities and affect the rotation.

[0026] In some technical solutions, a limiting ring a20 is installed at one outer end of the bearing seat 15, and a limiting ring b18 is installed at the other outer end of the bearing seat 15.

[0027] In this technical solution, the bearing seat 15 is fixed by the limiting rings a15 and b17.

[0028] In some technical solutions, the outer diameters of the limiting rings a20 and b18 are both larger than the inner diameter of the hinge cavity.

[0029] In this technical solution, the limiting ring a20 is set outside the hinge cavity, and the hinge cavity is also provided with an annular cavity for installing the limiting ring b18, thereby restricting the bearing seat 15 within the hinge cavity.

[0030] In some technical solutions, discharge ladders 6 are installed on both outer walls of the discharge bin 3.

[0031] In this technical solution, the material drop hopper 3 can be protected.

[0032] In some technical solutions, the limiting component includes an outer plate 174, a middle plate 173, and an inner plate 171. The four corners of the outer plate 174 and the middle plate 173 are hinged to each other. Springs 172 are hinged to the four corners of the other side of the middle plate 173. The other ends of the four springs 172 are hinged to the four corners of one side of the inner plate 171.

[0033] In this technical solution, the outer plate 174 is installed on the outer wall of the vibrating screen 9, and the inner plate 171 is extended and retracted by the springs 172 that are hinged to each other, thereby limiting it in the limiting cavity 11 and fixing the vibrating screen 9.

[0034] In some technical solutions, a protective plate 10 is installed inside the limiting cavity 11 at the upper end of the limiting component 17;

[0035] In this technical solution, the limiting cavity 11 is protected by the protective plate 10.

[0036] Working principle: When in use, firstly, the iron sheet is added into the vibrating screen box 1 through the feed hopper 2. The iron sheet falls onto the vibrating screen 9. At this time, the discharge bin 3 is vibrated by gravity. Impurities in the iron sheet fall into the vibrating screen box 1 through the vibrating screen 9, and other iron sheets enter the discharge bin 3. After use, the limiting component 17 is taken out from the limiting cavity 11, and the vibrating screen 9 is swung outward to clean it.
