Description

Technical Field

[0001] This application relates to the technical field of vibrating screen supports, and in particular to a high-stability sorting equipment frame with a composite vibration damping structure. Background Technology

[0002] In modern industrial production, sorting equipment is widely used for screening and separating various materials. However, sorting equipment generates significant vibrations during operation. These vibrations not only affect the normal operation of the equipment and reduce sorting accuracy, but also impact its service life. Furthermore, they generate considerable noise, negatively affecting the working environment. Sorting equipment (such as vibrating screens and air classifiers) is itself a vibration source; its vibrations are easily transmitted to the frame, causing overall shaking, affecting sorting accuracy and lifespan, and damaging the foundation.

[0003] The existing sorting equipment frame is insufficient in terms of vibration reduction and cannot effectively cope with the complex vibrations generated during equipment operation.

[0004] Therefore, a highly stable sorting equipment frame with good vibration reduction performance is needed to solve the above problems. Utility Model Content

[0005] To enhance the vibration reduction capabilities of the sorting equipment frame, this application provides a highly stable sorting equipment frame with a composite vibration reduction structure.

[0006] The high-stability sorting equipment frame with a composite vibration damping structure provided in this application adopts the following technical solution: A high-stability sorting equipment frame with a composite vibration damping structure includes a base frame. Primary vibration damping components are installed at the four corners of the lower end face of the base frame. Each primary vibration damping component includes a multi-legged bracket and rubber vibration isolators. The multi-legged bracket is inserted into the base frame, and the rubber vibration isolators are evenly sleeved on the lower ends of the multi-legged bracket. A set of H-shaped brackets and two sets of vertical tube seats are vertically installed on the upper end face of the base frame. The lower ends of the H-shaped brackets and vertical tube seats are vertically fixed to the upper end face of the base frame. Secondary vibration damping components are installed in both the H-shaped brackets and vertical tube seats. Spring supports are installed at the heads of the secondary vibration damping components, and the spring supports are fixedly connected to the secondary vibration damping components.

[0007] By adopting the above technical solution, primary vibration damping components are installed at the four corners of the lower end face of the base frame. Utilizing the elastic characteristics of rubber vibration isolators, the vertical and partial horizontal vibrations generated during the operation of the sorting equipment can be effectively buffered, reducing the transmission of vibration to the support surface below the base frame and thus minimizing the impact on the surrounding environment. Simultaneously, secondary vibration damping components are installed in the H-shaped bracket and vertical pipe base, with spring supports at their heads. These spring supports further absorb and disperse vibration energy, forming a composite vibration damping structure with the primary damping components. This improves the stability of the entire sorting equipment frame, ensuring the sorting equipment can operate in a stable environment and improving sorting accuracy.

[0008] Optionally, the base frame includes a frame, a reinforcing middle frame, and a frame shell for multi-leg brackets to be inserted and installed. The reinforcing middle frame is fixedly installed in the middle of the frame, and the frame shell is evenly fixed to the four corners of the lower end face of the frame.

[0009] By adopting the above technical solution, the base frame uses a structural design of a frame, a reinforced middle frame, and a shell. The reinforced middle frame is fixed in the middle of the frame, which can enhance the overall strength and stability of the frame and prevent the frame from deforming under stress. The shell is evenly fixed at the four corners of the lower end face of the frame, providing a stable installation position for the multi-legged bracket, ensuring that the primary vibration damping components can be accurately installed, and guaranteeing the stability of the vibration damping effect.

[0010] Optionally, the multi-leg bracket includes a central insert block, a diagonal brace assembly, and a disc base for mounting the rubber vibration isolator. The diagonal brace assembly is evenly installed on the outer side of the central insert block, and the disc base is fixedly installed at the lower end of the diagonal brace assembly.

[0011] By adopting the above technical solution, the structural design of the central insert block, diagonal brace assembly, and plate base of the multi-legged support, with the diagonal brace assembly evenly installed on the outer side of the central insert block, increases the support stability of the multi-legged support. The plate base is fixed to the lower end of the diagonal brace assembly, providing an installation foundation for the rubber vibration isolator, enabling the rubber vibration isolator to better perform its vibration reduction function, while also dispersing the pressure transmitted from the equipment to the rubber vibration isolator, thus extending the service life of the rubber vibration isolator.

[0012] Optionally, a top rubber sheet is provided on the upper end surface of the central insert block, and the top rubber sheet is glued and fixed to the central insert block.

[0013] By adopting the above technical solution, a top rubber sheet is provided on the upper end face of the central insert block, and the top rubber sheet is glued and fixed to the central insert block. When the multi-leg bracket is inserted into the frame of the base frame, the top rubber sheet can play a buffering role, reduce the rigid collision between the multi-leg bracket and the frame, further reduce vibration transmission, and at the same time prevent noise generated by friction between the multi-leg bracket and the frame.

[0014] Optionally, a central vertical rod is vertically provided at the center of the lower end face of the disc base for mounting the rubber vibration isolator, and the central vertical rod is fixedly connected to the disc base.

[0015] By adopting the above technical solution, a central vertical rod is set at the center of the lower end face of the disc base. The central vertical rod is fixedly connected to the disc base, providing an accurate installation position for the rubber vibration isolator and ensuring the stability and accuracy of the rubber vibration isolator installation. At the same time, the central vertical rod can enhance the vertical support capacity of the rubber vibration isolator, allowing the rubber vibration isolator to better perform its vibration reduction function.

[0016] Optionally, the H-shaped bracket includes a crossbar section and two sets of longitudinal tube sections. The two sets of longitudinal tube sections are arranged parallel to each other at both ends of the crossbar section and are fixedly connected to the crossbar section. The lower end of the longitudinal tube section is fixedly installed on the upper end face of the frame.

[0017] By adopting the above technical solution, the H-type support adopts a structural design of a horizontal bar section and two sets of longitudinal tube sections. The two sets of longitudinal tube sections are arranged parallel to each other at both ends of the horizontal bar section and are fixedly connected. This structure has high strength and stability, and can provide stable support for the secondary damping components. The lower end of the longitudinal tube section is fixedly installed on the upper surface of the frame, so that the H-type support and the base frame form an integral whole, enhancing the structural strength of the entire sorting equipment frame.

[0018] Optionally, a high-damping elastic layer is provided on the inner surface of both the longitudinal tube and the vertical tube base, and the high-damping elastic layer is adhered and fixed to both the longitudinal tube and the vertical tube base.

[0019] By adopting the above technical solution, a high-damping elastic layer is provided on the inner surface of the longitudinal tube section and the vertical tube base, and the high-damping elastic layer is bonded and fixed to both the longitudinal tube section and the vertical tube base. The high-damping elastic layer can absorb and dissipate the energy generated by the secondary vibration damping components during vibration, reduce the propagation of vibration in the longitudinal tube section and the vertical tube base, further improve the vibration damping effect, and also reduce the noise generated by vibration.

[0020] Optionally, the secondary damping assembly includes an insert inner tube, a rubber base, and a support plate for fixing the spring support. The insert inner tube has a hollow structure and is filled with particulate damping material. The rubber base is fixedly installed on the lower end face of the insert inner tube, and the support plate is fixedly installed on the head of the insert inner tube.

[0021] By adopting the above technical solution, the inner tube of the secondary damping component has a hollow structure, and the cavity is filled with particulate damping material. The particulate damping material can dissipate vibration energy through friction and collision between particles, effectively reducing the vibration amplitude. The rubber base is fixed to the lower end face of the inner tube, which can buffer the collision between the inner tube and the bottom of the H-shaped bracket or vertical tube seat, reducing vibration transmission. The support plate is fixed to the head of the inner tube, providing a stable installation platform for the spring support and ensuring that the spring support can function properly.

[0022] In summary, this application includes at least one of the following beneficial technical effects: This application employs a composite vibration damping structure combining primary and secondary vibration damping components to buffer and absorb vibrations generated during the operation of the sorting equipment from multiple levels and directions. The rubber vibration isolators in the primary damping component and the spring supports, particle damping materials, and other vibration damping elements in the secondary damping component work together to effectively reduce vibration amplitude and improve equipment stability. By setting vibration damping elements such as a top rubber sheet, a high-damping elastic layer, and a rubber base, rigid collisions and vibration propagation between equipment components are reduced, thereby effectively reducing noise generated by vibration and improving the working environment. A stable operating environment and good vibration damping effect can reduce wear and fatigue of various components of the sorting equipment, lower the equipment failure rate, extend the equipment's service life, and reduce equipment maintenance and replacement costs.
