Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, and in particular to a vibration-damping and noise-reducing screen body structure for a high-efficiency vibrating screen. Background Technology

[0002] Vibrating screens, as core equipment for material classification and processing, are widely used in mining, metallurgy, chemical and other fields. Traditional vibrating screens often use bolts to fix the screen mesh to the screen body, which results in low installation efficiency and high maintenance costs. At the same time, the vibration energy generated when the material impacts the screen mesh is directly transmitted to the screen body structure, which not only aggravates equipment wear, but also creates high-frequency noise pollution in the working environment.

[0003] Existing vibration reduction solutions mostly rely on adding passive vibration reduction elements such as springs or rubber pads, but they are difficult to achieve both screen fastening and vibration transmission control. Especially in heavy-duty screening scenarios, the screen edges are prone to structural fatigue fractures due to stress concentration.

[0004] Therefore, this application provides a vibration-damping and noise-reducing screen body structure for a high-efficiency vibrating screen to meet the requirements. Utility Model Content

[0005] The purpose of this application is to provide a vibration-damping and noise-reducing screen body structure for a high-efficiency vibrating screen, which aims to solve the problem that existing vibration reduction solutions mostly rely on adding passive vibration reduction elements such as springs or rubber pads, but it is difficult to achieve bidirectional control of screen fastening and vibration transmission.

[0006] To achieve the above objectives, this application provides the following technical solution: a vibration-damping and noise-reducing screen body structure for a high-efficiency vibrating screen, comprising a vibrating screen body, placement beams, and a screen mesh. Placement beams are provided on the inner wall of the vibrating screen body, with two placement beams arranged symmetrically in a group. The two placement beams are connected by a screen mesh, and a set of vibration-damping rubber strips are press-fitted between the placement beams and the screen mesh.

[0007] The top surface of the beam is provided with a rotating groove and a driving groove. A locking component is provided in the rotating groove, and a driving component is provided in the driving groove. The bottom surface of the screen is provided with a groove, and a hanging rod is provided in the groove. The hanging rod is slidably connected to the locking component.

[0008] The locking assembly also includes a rotating component and a locking rod. The rotating component is rotatably connected in the rotating groove, and a locking rod is provided on the top surface of the rotating component. The locking rod has an L-shaped cross-section and is slidably connected to the hanging rod.

[0009] The converter is driven by the driver component.

[0010] Preferably, the outer wall of the rotating part is provided with a slot, the locking rod is slidably connected in the slot, and a locking groove is provided in the middle of the slot, and a through hole is provided on the top surface of the locking rod, and the through hole and the locking groove are connected by a connecting bolt.

[0011] Preferably, a rubber sleeve is provided on the outer wall of the hanging rod.

[0012] Preferably, the drive assembly includes a worm and a worm wheel. The worm is rotatably connected in the drive groove, and a worm wheel meshing with it is provided below the worm. A hole is provided on the vibrating screen body, and a set of transmission rods is rotatably connected in the hole. The transmission rods are coaxially connected with the worm.

[0013] Preferably, each set of placement beams is provided with at least three sets of locking components.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] This invention features an elastic sandwich layer formed by vibration-damping rubber strips between the screen and the beam. This effectively absorbs the transient vibration energy generated by material impact. The mechanical energy is converted into heat energy through the viscoelastic deformation of the polymer material inside the rubber strips, reducing the intensity of vibration transmitted to the screen body. A worm gear transmission mechanism drives the L-shaped locking rod to rotate, utilizing the irreversible nature of the worm gear transmission to achieve mechanical self-locking, ensuring that the screen has no risk of displacement or loosening under high-frequency vibration conditions. Compared to traditional bolt fastening, installation time is reduced, and operation can be completed without special tools. Attached Figure Description

[0025] 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.

[0026] Example: Reference Figure 1-7 The high-efficiency vibrating screen shown has a vibration reduction and noise reduction screen body structure, including a vibrating screen body 1, placement beams 2, vibration damping rubber strips 3, and a screen 4. Placement beams 2 are provided on the inner wall of the vibrating screen body 1. Two placement beams 2 are arranged in a group and symmetrically arranged on the inner wall of the vibrating screen body 1. The two placement beams 2 are connected by the screen 4, and vibration damping rubber strips 3 are pressed between the screen 4 and the placement beams 2. The vibration damping rubber strips 3 reduce the noise and vibration generated when the material hits the screen 4 during processing. A locking component 5 and a driving component are provided on the placement beams 2. The locking component 5 is connected to the driving component, and the locking component 5 is detachably connected to the screen 4.

[0027] As one embodiment of this example, a rotating groove 20 and a driving groove 21 are provided on the top surface of the beam 2. The rotating groove 20 and the driving groove 21 are interconnected, and the locking component 5 and the driving component are respectively placed in the rotating groove 20 and the driving groove 21.

[0028] As one embodiment of this example, the locking component 5 has a set of rotating parts 50 rotatably connected in the rotating groove 20, and a set of locking rods 53 with an L-shaped cross section is provided on the outer wall of the rotating parts 50. In order to drive the rotating parts 50 to rotate through the driving component and limit the screen 4 with the locking rods 53, a groove 40 is provided on the bottom surface of the screen 4, and a set of cylindrical hanging rods 8 is provided in the groove 40. The locking rods 53 and the hanging rods 8 cooperate to achieve the purpose of fixing the screen 4 on the placement beam 2.

[0029] As one embodiment of this invention, a rubber sleeve is fitted on the outer wall of the hanging rod 8 to increase friction.

[0030] In one embodiment of this invention, a rectangular slot 51 is provided on the top surface of the rotating part 50, and the locking rod 53 is slidably connected in the slot 51. In order to fix the locking rod 53 in the slot 51, a through hole 54 is provided on the top surface of the locking rod 53. The through hole 54 has a T-shaped cross-section, and a locking groove 52 that matches the through hole 54 is provided in the middle of the slot 51. The connecting bolt 55 is slidably connected in the through hole 54, and the threaded section at its bottom is threadedly connected to the locking groove 52, thereby realizing a detachable connection between the locking rod 53 and the rotating part 50.

[0031] As one embodiment of this invention, the driving component includes a set of worm gears 7 rotatably connected in the driving groove 21, and the worm gears 7 are coaxially connected to the rotating part 50. Below the worm gears 7, there is a worm 6 that meshes with them. The worm 6 is coaxially connected to the transmission rod 9 rotatably connected to the vibrating screen body 1. Therefore, rotating the transmission rod 9 can drive the locking component 5 through the worm gears 7 and the worm 6, thereby achieving the fixed installation of the screen 4 on the placement beam 2.

[0032] The working principle of this practical application is as follows: After placing the screen 4 on the placement beam 2 of the vibrating screen body 1, the groove 40 at the bottom of the screen 4 aligns with the rotating groove 20 on the placement beam 2, allowing the locking rod 53 to pass through the damping rubber strip 3 and insert into the groove 40. Subsequently, by rotating the transmission rod 9, the transmission rod 9 drives the worm gear 6, which is coaxial with it, to rotate in the drive groove 21. The rotating worm gear 6 drives the worm wheel 7, which meshes with it, to rotate in the drive groove 21. The rotating worm wheel 7 drives the rotating component 50, which is coaxial with it, to rotate in the rotating groove 20. When the rotating component 50 rotates, it causes the locking rod 53 to move in the groove 40, and the L-shaped locking rod 53 engages with the hanging rod 8 to install the screen 4, thus completing the installation of the screen 4. Furthermore, the damping rubber strip 3 located between the placement beam 2 and the screen 4 achieves the effect of noise reduction and vibration reduction. Compared with the existing bolt fixing method, the above-mentioned installation method of the screen 4 is convenient, quick, and saves time and effort.

[0033] When the locking assembly 5 needs maintenance, after removing the screen 4 from above the placement beam 2, use a tool to rotate the connecting bolt 55 to pull the connecting bolt 55 out of the locking groove 52 and the through hole 54, release the limit between the rotating part 50 and the locking rod 53, then pull the locking rod 53 out of the slot 51 to complete the disassembly, and then replace it with a new locking rod 53.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
