Description

Technical Field

[0001] The utility model relates to the technical field of vibration screening equipment, in particular to a banana-shaped linear vibration screen. Background Art

[0002] Among the existing vibrating screening equipment, linear vibrating screens are widely used due to their high efficiency and stable screening performance. However, the traditional linear vibrating screen has certain limitations in the design of the supporting beams, such as rectangular or square beams are usually heavier than circular or other shaped beams, which may increase the weight and cost of the entire screening equipment, and may also affect the energy consumption and transportation cost of the equipment; the corners of the square beams are prone to stress concentration, especially under high-frequency vibration and heavy load conditions, which may cause fatigue damage and early failure of the beams; the processing and manufacturing of square beams may be more complicated than circular beams, requiring more processing steps and higher precision, which may increase production costs and time; the installation and maintenance of square beams may be more difficult than circular beams, because their shape may not be suitable for certain tools and equipment, or require more space and effort when disassembling and replacing; square beams may generate more noise and vibration during operation, especially at the corners and connection points of the beams, which may affect the operating environment and the stability of the equipment; Reference CN202322642829.9 A coal washing arc vibrating screen.
