Flip-Flow Screen Vibration for Reduced Height

The patent applies dynamic vibration to the screen machine frame, transforming it from a static structure to a dynamically active system. The vibratory motion creates artificial gravity components that enhance material transport along the screen surface, allowing the machine to operate effectively at reduced inclination angles while maintaining transport capability and reducing overall height.

The patent changes the operational parameters by introducing vibratory motion with specific frequency and amplitude characteristics. This parameter change modifies the effective gravity field acting on the material, enabling transport at lower inclination angles. The vibration parameters are optimized to achieve the desired transport effect without requiring the traditional large angle positioning.

The patent directly applies mechanical vibration to the screen machine frame through excitation elements that generate oscillatory motion. This vibration creates dynamic forces that propel material along the screen surface, compensating for the reduced gravitational component available at smaller inclination angles. The vibratory acceleration ensures adequate material transport capability even when the machine operates at reduced height.

By transforming the static frame into a dynamically vibrating structure, the patent enables the system to generate its own transport forces through controlled oscillation. This dynamic approach replaces the need for relying solely on gravitational force from large inclination angles, allowing effective operation at smaller angles while maintaining productivity.
