The invention discloses a lobster feeding device based on a suspension swing technology, and belongs to the technical field of
aquaculture. According to the scheme, when lobsters in a
drainage basin are fed, a swinging strip
rope is shaken firstly, the swinging strip
rope moves back and forth between throwing round holes, baits are promoted to gradually fall down from the throwing round holes, andmeanwhile, a magnetic
piston circular plate in an inverted storage
barrel can be promoted to move downwards. On one hand, air in an enrichment floating ball can be promoted to be extruded into an outwards-extending guide
pipe, therefore, the outwards-extending guide
pipe expands and extends to a horizontal state; and on the other hand, the repulsion effect of the magnetic
piston circular plate ona first magnetic end ball can be used, the first magnetic end ball is driven to drive the outwards-extending guide
pipe to extend outwards and to make the outwards-extending guide pipe more stable, afan-shaped connecting cloth piece is driven to be flatly laid on the water surface, fallen bait can be distributed on the fan-shaped connecting cloth piece, the lobsters can be promoted to be enriched on the lower side of the fan-shaped connecting cloth piece through the shading effect of the fan-shaped connecting cloth piece, and therefore lobster feeding efficiency is improved.
