<p>A ship loading and unloading machine comprises a support frame (6), the lower end of the support frame (6) serves to be arranged on a barge (8), the support frame is provided with a material reclaimer, a hopper (5) and a belt conveyor (1), the material reclaimer is arranged on one side of the hopper (5), and the belt conveyor (1) is arranged on the other side of the hopper (5), the belt conveyor (1) comprises a first conveying part (12) and a second conveying part (13), one end of the first conveying part (12) is fixedly connected with one end of the second conveying part (13), the first conveying part (12) is arranged horizontally, and the second conveying part (13) is arranged obliquely. Compared with the existing ship loading and unloading machines, the ship loading and unloading machine with the abovementioned structure features the use of a two-section design in the belt conveyor with one of the two sections being arranged obliquely, as a result of which the hopper can be prepositioned and moved downwards; and also, the hopper can be arranged at low attitude to lower the center of gravity thereof, thus effectively shortening the duration of a grab bucket for taking materials from an unloading ship to the hopper. Therefore, both stability and working efficiency are effectively improved at the same time.</p> |
