Mud flat moving mechanism

The utility model relates to a mud flat moving mechanism. The mud flat moving mechanism comprises a pair of buoyancy tanks and a track surrounding the buoyancy tanks. The pair of buoyancy tanks arranged side by side is connected as a whole through a front support rod and a rear support rod. The mud flat moving mechanism is characterized in that the track is of a double-chain structure, each of chains is composed of a first chain plate, a second chain plate, rollers, pin rolls, pins, fasteners and cubic columns. The first chain plate and the second chain plate are hinged to each other through the pin rolls and the pins. The pin rolls are movably sleeved with the rollers. The edge of the second chain plate is provided with a connecting base. The connecting base is connected and locked to a fastening base arranged at one end of every cubic column through the fasteners and a fastening base arranged at the other end of the cubic column is connected to the second chain plate in the same way. The mud flat moving mechanism uses a track structure with spaced cubic columns, so the track is not prone to attaching of a lot of mud and sand during working on the mud flat, the load of the moving track is decreased, the energy consumption is reduced, and the mud flat moving mechanism moves smoothly and forcefully.
