Technical Field

[0001] The utility model relates to the technical field of vibrating screens, in particular to an adjustable vibrating screen. Background Art

[0002] A vibrating screen generates a vibration frequency through a vibration motor. Small particle materials pass through the screen mesh and fall down, while large particle materials are blocked on the screen mesh, thereby screening out materials with different particle sizes.

[0003] In the prior art, during the use of the screen mesh of a vibrating screen, the screen hole specifications are fixed. However, during actual screening of materials, it is often necessary to screen materials of different specifications. At this time, the staff needs to replace the vibrating screen to ensure that the screen holes match, which brings inconvenience to the staff. Content of the Utility Model

[0028] Referring to Figures 1-6 as shown, this embodiment discloses an adjustable vibrating screen, including a vibrating screen body 1. An adjusting device 2 is provided inside the vibrating screen body 1, and the adjusting device 2 includes a first screen 21.

[0029] Referring to Figures 1-6As shown in the figure, the first screen 21 is fixedly connected to the inside of the vibrating screen body 1. A second screen 22 is slidably connected to the bottom of the first screen 21. A screw 23 is fixedly connected to the upper surface of the second screen 22. A reserved hole 24 is provided in the first screen 21 corresponding to the screw 23. The size of the reserved hole 24 is larger than the size of the screw 23. The arc surface of the screw 23 is threadedly connected with a nut 25. When it is necessary to adjust the size of the through holes between the first screen 21 and the second screen 22, first move the screw 23 in the reserved hole 24. The screw 23 drives the second screen 22 to slide at the bottom of the first screen 21. At this time, the partition on the second screen 22 will block part of the holes of the first screen 21, thus achieving the effect of adjusting the holes of the first screen 21. After moving the second screen 22 to a suitable position, rotate the nut 25. The nut 25 presses the first screen 21, achieving the effect of fixing the second screen 22. Through the adjusting device 2, the effect of adjusting the size of the holes between the first screen 21 and the second screen 22 is achieved, facilitating the vibrating screen body 1 to screen materials of different specifications and sizes, and improving the practicability of the vibrating screen body 1.

[0030] Refer to Figures 1-6 As shown in the figure, two control blocks 26 are fixedly connected to the arc surface of the nut 25. The two control blocks 26 are centrosymmetric. By setting the control blocks 26, the effect of facilitating the staff to rotate the nut 25 is achieved, bringing convenience to the staff. A plurality of rubber strips 27 are fixedly connected to the upper surface of the first screen 21. The plurality of rubber strips 27 are equally divided into two groups. The two groups of rubber strips 27 are respectively located on both sides of the reserved hole 24. By setting the rubber strips 27, the friction between the nut 25 and the first screen 21 is increased, facilitating the nut 25 to press the first screen 21 for fixation. Two symmetrically arranged sliding plates 28 are fixedly connected to the side of the second screen 22 close to the first screen 21. A sliding groove 29 is provided in the first screen 21 corresponding to the sliding plate 28. The sliding plate 28 is slidably adapted to the sliding groove 29. By moving the sliding plate 28 on the second screen 22 in the sliding groove 29 of the first screen 21, the effect of restricting the moving direction of the second screen 22 is achieved, improving the stability of the movement of the second screen 22.

[0031] Refer to Figures 1-6As shown in the figure, an auxiliary device 3 is provided at the corresponding reserved hole 24 of the first screen 21. The auxiliary device 3 includes a protective cover 31. The protective cover 31 is fixedly connected to the upper surface of the first screen 21. The reserved hole 24 is located inside the protective cover 31. One side of the protective cover 31 is slidably penetrated by a cover plate 32. The size of the cover plate 32 is adapted to the internal size of the protective cover 31. A second magnet 34 is fixedly connected to one side of the protective cover 31. A first magnet 33 is fixedly connected to the upper surface of the cover plate 32. The first magnet 33 and the second magnet 34 attract each other. When it is necessary to rotate the nut 25 inside the protective cover 31, the staff first pulls the cover plate 32. The cover plate 32 moves on the protective cover 31. When the nut 25 below the cover plate 32 and the reserved hole 24 are exposed, the staff rotates the nut 25 at this time. After operating the nut 25, the staff releases the cover plate 32. Under the action of the mutual attraction of the first magnet 33 and the second magnet 34, the cover plate 32 covers the inside of the protective cover 31 again. Through the auxiliary device 3, the reserved hole 24 inside the protective cover 31 is protected, preventing materials from entering the reserved hole 24, thereby avoiding the situation that it is inconvenient for the staff to move the screw rod 23.

[0032] Referring to Figures 1-6 As shown in the figure, one end of the cover plate 32 is fixedly connected with a pull plate 35, and the surface of the pull plate 35 is provided with anti-slip lines. By setting the pull plate 35, the effect of facilitating the staff to move the cover plate 32 is achieved, bringing convenience to the staff. A plurality of reinforcing ribs 36 are fixedly connected to the upper surface of the cover plate 32. The plurality of reinforcing ribs 36 are linearly distributed. By setting the reinforcing ribs 36, the overall strength of the cover plate 32 is increased, avoiding damage to the cover plate 32 after long-term use.

[0033] Working principle: When it is necessary to adjust the size of the through holes between the first screen 21 and the second screen 22, first move the screw rod 23 in the reserved hole 24. The screw rod 23 drives the second screen 22 to slide at the bottom of the first screen 21. The sliding plate 28 on the second screen 22 moves in the sliding groove 29 of the first screen 21, achieving the effect of restricting the moving direction of the second screen 22. At this time, the partition on the second screen 22 blocks part of the holes of the first screen 21, thereby achieving the effect of adjusting the holes of the first screen 21. After moving the second screen 22 to a suitable position, the staff rotates the nut 25 through the control block 26. The nut 25 presses the rubber strip 27 on the first screen 21, achieving the effect of fixing the second screen 22. Through the adjusting device 2, the effect of adjusting the size of the holes between the first screen 21 and the second screen 22 is achieved, facilitating the vibrating screen body 1 to screen materials of different specifications and sizes, and improving the practicability of the vibrating screen body 1.

[0034] When it is necessary to rotate the nut 25 inside the protective cover 31, the staff first pulls the cover plate 32 through the pull plate 35. The cover plate 32 moves on the protective cover 31. When the nut 25 and the reserved hole 24 below the cover plate 32 are exposed, the staff rotates the nut 25 at this time. After operating the nut 25, the staff loosens the pull plate 35. Under the mutual attraction of the first magnet 33 and the second magnet 34, the cover plate 32 covers the inside of the protective cover 31 again. Through the auxiliary device 3, the reserved hole 24 inside the protective cover 31 is protected, preventing materials from entering the reserved hole 24, thus avoiding the situation where it is inconvenient for the staff to move the screw rod 23.
