AI Technical Summary
Existing grab bucket unloading devices are prone to dust leakage from gaps during unloading, causing environmental pollution. Furthermore, existing dust suppression measures have poor sealing performance and cannot form an effective fully enclosed dustproof space.
A dust suppression funnel comprising a dust-blocking structure and a dust-collecting structure was designed. The dust-blocking structure is sealed by a folded cloth and a dust cover, while the dust-collecting structure absorbs dust through a multi-channel dust collection system. Combined with the inverted V-shaped design of the inclined discharge plate and the dust-blocking plate, a double barrier is formed. The dust-collecting cloth and magnets adsorb and seal the dust, achieving full-process dust interception.
It effectively reduces dust dispersion, improves the cleanliness of the working environment, meets the requirements of environmental protection operations, and achieves a highly efficient dust suppression effect.
