Description

Technical Field

[0001] This utility model relates to the field of vibrating screening equipment, and in particular to an automatic impurity removal and cleaning mechanism for vibrating screens. Background Technology

[0002] In the existing field of vibrating screening equipment, traditional vibrating screens mainly rely on a single vertical vibration principle for screening. Materials tend to accumulate on the screen, making it difficult for fine materials to pass through the screen quickly, resulting in low screening efficiency.

[0003] Meanwhile, the materials being screened often contain particles similar in size to the mesh size of the screen. These particles are very easy to get stuck in the mesh, which seriously affects the screening efficiency.

[0004] To address the aforementioned issues, this patent proposes a vibrating screen solution that can efficiently clean the screen mesh, thereby resolving the technical problems mentioned above. Utility Model Content

[0005] The main purpose of this utility model is to propose an automatic impurity removal and cleaning mechanism for vibrating screens, which aims to solve the problems of material accumulation, low screening efficiency, and easy clogging of mesh in traditional vibrating screens, thus affecting screening efficiency.

[0006] To address the aforementioned problems, this utility model proposes an automatic impurity removal and cleaning mechanism for a vibrating screen, comprising a limiting frame that extends vertically and opens to the left. A mesh frame is snapped into the limiting frame and slidably connected to it. A screen is installed inside the lower end of the mesh frame. A vibrating frame is connected to the left end of the mesh frame, and a vibrating component is installed inside the vibrating frame. The vibration generated by the vibrating component cleans the blockage inside the mesh of the screen. A swinging component is installed at the rear end of the vibrating frame, and the mesh frame and the screen can swing back and forth inside the limiting frame via the swinging component.

[0007] Preferably, the vibration component includes a curved shaft, the front end of the vibration frame is connected to a drive motor, and the rear end of the drive motor is rotatably connected to a curved shaft whose outer wall is composed of multiple spaced concave and convex surfaces via a motor shaft.

[0008] Preferably, the curved shaft is provided with a plurality of vibration sleeves connected to the inner wall of the upper end and the inner wall of the right end of the vibration frame, and each of the plurality of vibration sleeves is slidably connected to a vibration head inside its outer end.

[0009] Preferably, the outer end of the vibrating head is hemispherical, and the inner wall of the hemispherical outer wall is provided with a ball bearing that fits against the outside of the curved shaft, and the inner end of the vibrating head is provided with a vibration spring located inside the vibration sleeve.

[0010] Preferably, the rocking assembly includes a linkage disk, the rear end of the curved shaft is connected to the linkage disk located at the rear end of the vibration frame, and the outer side of the rear end of the linkage disk is connected to an eccentric rotating shaft.

[0011] Preferably, the right rear end of the limiting frame is connected to a positioning pivot at the same height as the curved surface axis, and a push-pull pivot is rotatably connected between the eccentric pivot and the positioning pivot.

[0012] Preferably, multiple balance springs are connected between the right end of the vibration frame and the inner wall of the right end of the limiting frame, and multiple drag-reducing ball bearings that fit against the inner wall of the limiting frame are provided on both the front and rear sides of the lower end of the vibration frame. Beneficial effects

[0013] 1. This utility model sets up a swing component and a vibration component between the limiting frame and the screen frame, so that the screen frame and the screen can swing back and forth left and right through the swing component, and perform multi-directional compound vibration by the vibration component, which can improve screening efficiency and prevent screening materials and debris from clogging the screen mesh. At the same time, it shakes out the screening materials and debris clogging the screen mesh, and efficiently cleans the screen.

[0014] 2. The swing component and the vibration component of this utility model are driven by a set of drive components, so that the swing component and the vibration component can operate synchronously and work together to quickly disperse the screened material and separate it from the impurities, avoiding accumulation. At the same time, the composite vibration quickly passes through the screen, further improving the screening efficiency and cleaning efficiency.

[0015] 3. The vibrating head of this utility model is provided with a ball bearing at the end, and the ball bearing makes rolling contact with the concave and convex surfaces of the curved shaft. At the same time, the lower end of the mesh frame slides with the limiting frame through the drag-reducing ball bearing, thereby reducing frictional resistance and reducing wear between components.

[0016] 4. The mesh frame of this utility model, through the cooperation of the balance spring and the drag-reducing ball, balances the motion inertia while reducing frictional resistance, making the mesh frame and screen swing more smoothly and steadily. Attached Figure Description

[0020] 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.

[0021] To achieve the above-mentioned utility model objectives, such as Figures 1-5 As shown, this utility model provides an automatic impurity removal and cleaning mechanism for a vibrating screen, including a limiting frame 1, which is vertically continuous and opens to the left. Support legs are connected to the four corners of the lower end of the limiting frame 1 for bottom support. A mesh frame 2 is snapped into the limiting frame 1 and slidably connected to it. A screen 3 is installed inside the lower end of the mesh frame 2. A vibrating frame 4 is connected to the left end of the mesh frame 2. A vibrating component is installed inside the vibrating frame 4, and the vibration generated by the vibrating component cleans the blockage inside the mesh of the screen 3. A swinging component is installed at the rear end of the vibrating frame 4. The frame 2 and screen 3 can swing back and forth inside the limiting frame 1 via the swing assembly. During the operation of the vibrating screen, the material to be screened is placed inside the frame 2 and screened through the screen 3 to remove impurities inside the material. The frame 2 and screen 3 can swing back and forth left and right inside the limiting frame 1 via the swing assembly at the rear end of the vibrating frame 4, which drives the material to be screened to roll back and forth on the upper end of the screen 3. This can accelerate the separation of the material from the impurities, improve the screening efficiency, and speed up the process of the material passing through the mesh of the screen 3, thus avoiding clogging of the mesh of the screen 3.

[0022] In addition, the screen frame 2 and the screen 3 can generate vibration through the vibration component, which can shake out the screening materials and debris blocked inside the mesh of the screen 3, thus preventing the mesh of the screen 3 from clogging, and cleaning the mesh of the screen 3 at the same time.

[0023] Preferably, the vibration assembly includes a curved shaft 6, a drive motor 5 connected to the front end of the vibration frame 4, and a curved shaft 6 with an outer wall composed of multiple spaced concave and convex surfaces rotatably connected to the rear end of the drive motor 5 via a motor shaft. Multiple vibration sleeves 7 are provided outside the curved shaft 6, connected to the upper inner wall and the right inner wall of the vibration frame 4. Vibration heads 8 are slidably connected to the inner ends of the multiple vibration sleeves 7. The outer end of the vibration head 8 is hemispherical, and the inner wall of the hemispherical outer wall contains ball bearings 16 that conform to the outside of the curved shaft 6. A vibration spring 9 is located inside the vibration sleeve 7 at the inner end of the vibration head 8. During the cleaning process of the mesh of screen 3, the drive motor 5 is connected to an external power source through a wiring harness. When the drive motor 5 is started, it drives the curved shaft 6 to rotate. Since the vibrating head 8 is elastically connected to the inside of the vibrating sleeve 7 through the vibration spring 9 and is in contact with the concave and convex outer wall of the curved shaft 6 through the contact ball 16, the vibrating head 8 will bounce continuously on the outer wall of the curved shaft 6, thereby generating vibration and driving the screen frame 2 and screen 3 to vibrate, shaking out the screened materials and impurities inside the mesh of screen 3, improving screening efficiency, and cleaning the mesh of screen 3.

[0024] In addition, multiple vibrating heads 8 located on the inner wall of the right end of the vibrating frame 4 will generate left-right vibrations, and multiple vibrating heads 8 located on the inner wall of the upper end of the vibrating frame 4 will generate up-down vibrations, so that multiple vibrating heads 8 can drive the mesh frame 2 and the screen 3 to generate multi-directional composite vibrations, so that the screened materials and impurities inside the mesh of the screen 3 can be shaken out more easily.

[0025] In addition, the vibrating head 8 can transform the frictional connection with the curved shaft 6 into a rolling connection through the contacting ball 16, thereby reducing the wear between the curved shaft 6 and the vibrating head 8, which can reduce kinetic energy loss, make it more energy-efficient, and improve the service life of the curved shaft 6 and the vibrating head 8.

[0026] Preferably, the swing assembly includes a linkage disk 10. The rear end of the curved shaft 6 is connected to the linkage disk 10 located at the rear end of the vibrating frame 4, and an eccentric rotating shaft 11 is connected to the outer side of the rear end of the linkage disk 10. A positioning rotating shaft 12, located at the same height as the curved shaft 6, is connected to the right side of the rear end of the limiting frame 1. A push-pull rotating rod 13 is rotatably connected between the eccentric rotating shaft 11 and the positioning rotating shaft 12. Multiple balance springs 14 are connected between the right end of the vibrating frame 4 and the inner wall of the right end of the limiting frame 1. Multiple resistance-reducing ball bearings 15 are provided on both the front and rear sides of the lower end of the vibrating frame 4 and are attached to the inner wall of the limiting frame 1. During the swinging process of the screen frame 2 and the screen 3, the drive motor 5 drives the linkage disk 10 to rotate through the curved shaft 6. The linkage disk 10 drives the push-pull rotating rod 13 to rotate through the eccentric rotating shaft 11. Since the other end of the push-pull rotating rod 13 is rotatably connected to the outside of the limiting frame 1 through the positioning rotating shaft 12 and fixed. At the same position, and with the positioning shaft 12 and the curved shaft 6 at the same height, when the linkage disk 10 drives the eccentric shaft 11 to rotate, the eccentric shaft 11 will move closer to the positioning shaft 12 and further away from it. Meanwhile, the length of the push-pull rod 13 remains unchanged, causing the push-pull rod 13 to push and pull the linkage disk 10 and the eccentric shaft 11. Through the curved shaft 6, the vibrating frame 4 moves back and forth towards and away from the left end of the positioning shaft 12, allowing the vibrating frame 4 to drive the mesh frame 2 and the screen 3 to slide back and forth inside the limiting frame 1, thus generating a swing. At the same time, the mesh frame 2 and the screen 3 can balance the inertia of the left and right sliding through multiple balance springs 14, allowing the mesh frame 2 and the screen 3 to change the direction of sliding more easily. The frictional resistance between the mesh frame 2 and the limiting frame 1 is reduced by multiple friction-reducing balls 15 at the lower end of the mesh frame 2, reducing energy consumption and wear.

[0027] In addition, the screen frame 2 and the screen 3 can swing back and forth to make the screening material roll back and forth on the upper end of the screen 3, so that the screening material can be quickly dispersed, improving the separation efficiency of the screening material and the impurities, and improving the screening efficiency. At the same time, the dispersed screening material can pass through more meshes inside the screen 3, improving the efficiency of the screening material passing through the mesh and avoiding accumulation that would cause the mesh of the screen 3 to become clogged.

[0028] In addition, both the vibration component and the oscillating component are driven by the drive motor 5 and the curved shaft 6, using the same drive system, which enables the vibration component and the oscillating component to operate synchronously and work together to further improve screening efficiency and cleaning efficiency.

[0029] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
