Dust collection and rust removal device for ship maintenance

The invention relates to the technical field of ship maintenance, in particular to a dust collection and rust removal device for ship maintenance, which comprises a box body, a polishing motor mechanism and a transverse moving mechanism are arranged in an inner cavity of the box body, a pneumatic clamping jaw is mounted on the polishing motor mechanism, a polishing assembly is mounted on the transverse moving mechanism, and an opening is formed in the bottom of the box body. And a ship-shaped switch is arranged on the inner wall of the box body. When different rusts on a ship deck are polished, the polishing assemblies can be driven to move through the transverse moving mechanism, and the appropriate polishing assemblies are moved to the position below the polishing motor mechanism; then the polishing assembly is clamped and fixed through a polishing motor mechanism and a pneumatic clamping jaw and then pushed out of the bottom of the box body so as to polish the rust of the deck, and after polishing is compl
