Beach weed removing machine

The invention relates to a beach weed removing machine which comprises a machine body and a control panel. The machine body comprises a walking assembly, a rotary cultivator and corresponding hydraulic motors. The walking assembly comprises a pair of floating boxes and tracks surrounding the floating boxes. The hydraulic motors control the corresponding tracks and the rotary cultivator to act. The beach weed removing machine is characterized in that each track is of a double-chain structure, each chain is formed by a first chain plate, a second chain plate, a rolling column, a hinge pin, dowels, fasteners and a cubic column bar, the first chain plates and the second chain plates are hinged through the hinge pins and the dowels, the hinge pins are movably sleeved with the rolling columns, connecting bases are arranged on the edges of the second chain plates, the connecting bases and fastening bases arranged at one ends of the cubic column bars are connected and locked through the fasteners, and fastening bases at the other ends of the cubic column bars are connected with the second chain plates of the other chain in the similar mode. By means of the track structure, the beach walking property of the whole machine is improved, the operation efficiency is improved, energy consumption is reduced, and the problem that beach weeds are difficult to remove is effectively solved.
