Abstract
Description
Technical Field
[0001] This utility model relates to the field of spring assembly technology, specifically a composite rubber spring assembly for a vibrating screen. Background Technology
[0002] The spring assembly of a vibrating screen is a key component. The spring assembly provides the necessary support force for the screen box, ensuring that the screen box maintains a stable position and posture during vibration, so that the screening operation can proceed normally.
[0003] Composite rubber springs combine the advantages of metal springs and rubber springs. They are typically made by wrapping a layer of rubber material around a metal helical spring. Existing spring assemblies are not stable enough under pressure and lack pressure balancing devices, which makes the springs easily damaged or broken. The damping springs in existing vibrating screen buffer spring assemblies are often exposed and prone to corrosion and rust. In view of this, a composite rubber spring assembly for vibrating screens is proposed. Utility Model Content

[0008] The pressure pipe is equipped with a buffer mechanism, which includes a rubber protective cover, a fixed plate, an upper lifting ring, a piston rod, a spring, a working piston, hydraulic oil, a floating piston, an inflatable shock-absorbing zone, a nano-coating, a neoprene rubber coating, and a rubber protective sleeve.

[0017] (III) Beneficial Effects
[0018] Compared with the prior art, the present invention provides a composite rubber spring assembly for a vibrating screen, which has the following advantages:
[0019] 1. The composite rubber spring assembly used in the vibrating screen flows in the hydraulic oil in the gap between the piston and the cylinder. Due to the viscosity of the liquid, it generates resistance that hinders the movement of the working piston, thus buffering and absorbing vibration energy. At this time, the hydraulic oil pushes the floating piston downward. Due to the compressibility of gas, it can absorb and release pressure through compression or expansion, maintain the relative stability of the system pressure, and prevent the spring assembly from being damaged by excessively high or low pressure.
[0020] 2. The composite rubber spring assembly used in the vibrating screen has a neoprene coating that prevents chemicals from contacting the rubber spring body, avoids corrosion of the rubber spring, and ensures the stability of its performance. The nano-coating can further enhance the elasticity and flexibility of the rubber spring without affecting its elasticity, so that the rubber spring can more effectively absorb and buffer vibration energy when subjected to external forces, thereby improving the shock absorption effect.

[0026] 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.
[0027] Please see Figure 1-4 This utility model provides a new technical solution: a composite rubber spring assembly for a vibrating screen, including a pressure tube 1, and a lower lifting ring 2 fixedly installed on the lower surface of the pressure tube 1;
[0028] The pressure pipe 1 is equipped with a buffer mechanism, which includes a rubber protective cover 3, a fixed plate 4, an upper lifting ring 5, a piston rod 6, a spring 7, a working piston 8, hydraulic oil 9, a floating piston 10, an inflatable shock-absorbing zone 11, a nano-coating 12, a neoprene rubber coating 13, and a rubber protective sleeve 14.
[0029] Furthermore, the rubber protective cover 3 is fixedly installed on the upper surface of the pressure pipe 1, and the fixing plate 4 is fixedly installed on the upper surface of the rubber protective cover 3.
[0030] The upper lifting ring 5 is fixedly installed on the upper surface of the fixing plate 4.
[0031] Furthermore, the piston rod 6 is fixedly installed on the lower surface of the fixed plate 4, and the lower end of the piston rod 6 penetrates into the pressure tube 1.
[0032] Furthermore, the working piston 8 is fixedly installed at the lower end of the piston rod 6, and the hydraulic oil 9 is installed inside the pressure pipe 1.
[0033] Furthermore, the floating piston 10 is slidably sleeved on the inner surface of the pressure tube 1, and the air-filled shock-absorbing zone 11 is disposed on the lower surface of the floating piston 10.
[0034] Furthermore, the spring 7 is fixedly installed on the upper surface of the pressure tube 1, and the upper end of the spring 7 is fixedly installed on the lower surface of the fixing plate 4.
[0035] Furthermore, the rubber protective sleeve 14 is fixedly sleeved on the outer surface of the spring 7, and the neoprene coating 13 is connected to the outer surface of the rubber protective sleeve 14.
[0036] The nano-coating 12 is connected to the outer surface of the chloroprene rubber coating 13;
[0037] When in use, the composite rubber spring assembly for the vibrating screen is fixedly installed between the frame and the vibrating screen via the upper lifting ring 5 and the lower lifting ring 2. When the vibrating screen vibrates, the upper lifting ring 5 applies a downward thrust to the fixed plate 4 fixedly installed on the lower surface, causing it to move downward. The fixed plate 4 applies a downward thrust to the piston rod 6 fixedly installed on the lower surface, and the piston rod 6 applies a downward thrust to the working piston 8 fixedly installed on the lower surface. The hydraulic oil 9 flows in the gap between the piston and the cylinder. Due to the viscosity of the liquid, it generates resistance that hinders the movement of the working piston 8, thus buffering and absorbing vibration energy. At this time, the hydraulic oil 9 pushes the floating piston 10 downward. Utilizing the compressibility of gas, it can absorb and release pressure through compression or expansion, maintaining a relatively stable system pressure. To prevent damage to the spring assembly due to excessive or insufficient pressure, the fixing plate 4 applies pressure to the spring 7 fixedly mounted on the lower surface while moving. The spring 7 undergoes elastic deformation, converting external mechanical energy into elastic potential energy for storage, thus buffering vibration. The neoprene rubber coating 13 provides an effective protective barrier for the spring 7, giving it good resistance to many chemicals. The neoprene rubber coating 13 prevents chemicals from contacting the rubber spring body, avoiding corrosion and ensuring the stability of its performance. The nano coating 12 can further enhance the elasticity and flexibility of the rubber spring without affecting its elasticity, enabling the rubber spring to absorb and buffer vibration energy more effectively when subjected to external forces, thereby improving the shock absorption effect.
[0038] The composite rubber spring assembly used in the vibrating screen flows through the hydraulic oil 9 in the gap between the piston and the cylinder. Due to the viscosity of the liquid, it generates resistance that hinders the movement of the working piston 8, thus buffering and absorbing vibration energy. At this time, the hydraulic oil 9 pushes the floating piston 10 downward. Due to the compressibility of gas, it can absorb and release pressure through compression or expansion, maintaining the relative stability of the system pressure and preventing damage to the spring assembly caused by excessively high or low pressure. The chloroprene rubber coating 13 of the composite rubber spring assembly used in the vibrating screen can prevent chemical substances from contacting the rubber spring body, avoiding corrosion of the rubber spring and ensuring the stability of its performance. The nano coating 12 can further enhance the elasticity and flexibility of the rubber spring without affecting its elasticity, so that the rubber spring can more effectively absorb and buffer vibration energy when subjected to external force, improving the shock absorption effect.
[0039] Structural Description:
[0040] Pressure tube 1: As the main structure of the entire assembly, it provides space for the installation and operation of other components, and bears and transmits forces from the upper and lower lifting rings.
[0041] Lower lifting ring 2: Used to fix the composite rubber spring assembly on the vibrating screen, serving to connect and support the entire assembly, so that the assembly can be stably connected to the vibrating screen and ensure that the vibration of the vibrating screen can be transmitted to the spring assembly.
[0042] Rubber protective cover 3: Installed on the upper surface of pressure pipe 1, its main function is to protect the internal components and prevent external dust, impurities, moisture and other substances from entering the pressure pipe, so as to avoid contamination and damage to the internal hydraulic oil, piston and other components, and extend the service life of the components.
[0043] Fixed plate 4: It serves to connect and transmit force, transferring the force from the upper lifting ring 5 to the piston rod 6, and also provides a fixed position for the spring 7 to be installed, ensuring that the spring 7 can play a buffering role in the correct position.
[0044] Upper lifting ring 5: Used to fix the composite rubber spring assembly on the frame. It is the connection point between the entire assembly and the frame, enabling the assembly to withstand the vibration from the vibrating screen and transmit it to the entire spring assembly for buffering and shock absorption.
[0045] Piston rod 6: Transmits the force on the fixed plate 4 to the working piston 8, enabling the working piston 8 to move within the pressure pipe 1, thereby driving the hydraulic oil 9 to flow and achieving the functions of buffering and shock absorption.
[0046] Spring 7: By undergoing elastic deformation, it converts external mechanical energy into elastic potential energy and stores it. When the vibration of the vibrating screen stops or the force disappears, spring 7 can convert the stored elastic potential energy into mechanical energy and release it, thus buffering the vibration, reducing the impact of vibration on the equipment, and making the movement of the vibrating screen more stable.
[0047] Working piston 8: Driven by piston rod 6, it moves inside pressure pipe 1. By squeezing hydraulic oil 9, it causes hydraulic oil to flow inside pressure pipe. The viscosity of hydraulic oil generates resistance that hinders the movement of working piston 8, thereby achieving the function of buffering and absorbing vibration energy.
[0048] Hydraulic oil 9: Utilizing its viscosity, it flows in the gap between the piston and cylinder when the working piston 8 moves, generating resistance to buffer and absorb vibration energy. At the same time, it can also drive the floating piston 10 to move when the pressure changes, so as to achieve pressure balance and regulation.
[0049] Floating piston 10: Under the pressure of hydraulic oil 9, it slides in pressure pipe 1, separating the pneumatic damping zone 11 from the hydraulic oil 9. It moves up and down according to the pressure change of hydraulic oil, thereby adjusting the volume of the pneumatic damping zone 11 and using the compressibility of gas to absorb and release pressure.
[0050] Inflatable shock absorption zone 11: Utilizing the compressibility of gas, it absorbs and releases pressure through compression or expansion when the system pressure changes, maintaining the relative stability of the system pressure, preventing damage to the spring assembly due to excessively high or low pressure, and assisting the entire spring assembly in better performing its shock absorption and buffering function.
[0051] Nano-coating 12: Without affecting the elasticity of the rubber spring itself, it further enhances its elasticity and flexibility, enabling the rubber spring to absorb and buffer vibration energy more effectively when subjected to external forces, thereby improving the shock absorption effect.
[0052] Neoprene coating 13: Provides an effective protective barrier for spring 7, making it resistant to many chemicals, preventing chemicals from contacting the rubber spring body, avoiding corrosion of the rubber spring, and ensuring the stability of its performance.
[0053] Rubber protective sleeve 14: Applied to the outer surface of spring 7, it protects spring 7 from mechanical damage such as scratches and collisions from external objects, and also isolates spring 7 from the influence of external environmental factors to a certain extent. 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.
