[0002] The movable multi-stage stone vibration screening device combined with image recognition technology can achieve efficient stone screening and sorting. It performs step-by-step screening through multiple vibrating screen levels to adapt to stones of different particle sizes.

The image recognition system performs data analysis on the screened stones and optimizes the screening process.

[0003] However, most of the current stone vibration screening devices have the following problems:

[0004] For example, a stone vibrating screening device with the announcement number CN210906857U, due to the uneven distribution of material particle size, large-particle stone often causes greater impact and wear on the screen, affecting the screening effect and screen life. At the same time, the continued presence of large-particle stone will also reduce the screening efficiency, increase energy consumption, and make it inconvenient to improve the screening effect; at the same time, for example, a limestone screening vibrating screen with the announcement number CN205128394U, when using an eccentric wheel to rotate and generate vibration for screening, the weight of the eccentric wheel is mostly fixed.
