Description

Technical Field

[0001] This utility model specifically relates to the field of protective frame technology, specifically a foldable protective frame for coal and gangue sorting screens. Background Technology

[0002] In coal sorting operations, screens are key components for separating coal and gangue. During operation, they are easily damaged by the impact and compression of coal and gangue, affecting sorting efficiency and quality. Traditional screen protection frames are mostly fixed structures, which have many drawbacks: on the one hand, fixed structures are inconvenient to transport and store, and are cumbersome to operate when relocating to different work sites; on the other hand, they are difficult to adapt to different screen specifications and to flexibly adjust the working angle to meet diverse sorting needs, resulting in great limitations in their use.

[0003] Existing protective frames fail to meet the requirements of modern coal sorting operations in terms of structural stability, screen compatibility, and ease of operation. For example, in Xining screening operations, they cannot effectively adjust the screening angle of the screen. Furthermore, traditional protective frames can only be fixedly installed for one size of screen. Therefore, when different screen sizes are installed according to the needs of the work environment, traditional protective frames cannot effectively meet the screening requirements. Utility Model Content
