Conveying machine for loading and unloading vehicle

Provided is a conveying machine for a loading and unloading vehicle. The conveying machine comprises a machine frame and a main conveying mechanism arranged on the machine frame. The main conveying mechanism comprises a main conveying machine frame, a main conveyor belt arranged on the main conveying machine frame and a driving motor driving the main conveyor belt to operate. The conveying machine further comprises secondary conveying mechanisms linked with the main conveying mechanism for transmission. The conveying machine for the loading and unloading vehicle has following beneficial effects: due to the fact that power is provided by the main conveying mechanism and the conveying distance is extended by the secondary conveying mechanisms, the carrying distance of workers is decreased and labor intensity is reduced; and due to the fact that the main conveying mechanism and the secondary conveying mechanisms are of detachable structures and the multiple secondary conveying mechanism can be linked, the conveying machine is simple in structure, convenient in detachment, flexible in usage and low in cost.
