Description

Technical Field

[0001] The utility model relates to the field of crushing equipment maintenance devices, in particular to an automatic flip cover hydraulic safety latch device for high-viscosity scrap metal physical shredding equipment. Background Art

[0002] In the process of shredding highly sticky scrap metal, a shredder is required. During the shredding process, the top cover of the shredder needs to be locked. Only in this way can the safety of the operation be guaranteed. However, the existing shredder does not have a locking device. At this time, the working chamber is completely closed by the equipment's own weight. If there is a non-closed working chamber during the operation of the equipment, it will cause certain safety hazards.

[0003] Although there are also latch-type locking devices available, existing safety latches require manual insertion or mechanical linkage latches. As equipment becomes larger and larger, safety latches become increasingly bulky. Manual insertion and linkage methods are also very inconvenient and pose certain safety risks during operation.

[0004] Furthermore, during operation, the equipment may be blocked, and when this happens, the top cover needs to be opened and locked to ensure safety during maintenance. However, the existing equipment lacks a locking device, which creates a safety hazard during maintenance. Utility Model Content
