Arranging two conveying platforms in small places in individual cargo terminals will cause congestion when transporting goods. In view of the above situation, a modular and efficient bulk cargo transport trailer system was invented. The conveying surface height of the modular and efficient bulk cargo transport trailer system is the same as that of the aviation pallet trailer. Therefore, the conveying equipment of the aviation pallet trailer can be used, which improves the transfer efficiency of goods and saves the maintenance cost of the conveying equipment.

[0064] like Figures 1 to 7As shown, first, when in use, the modular and efficient bulk cargo transport trailer system is towed to the entrance of the conveying equipment by the airport tractor. After the vehicle is aligned with the entrance of the conveying equipment, the baffle 6 that limits the integrated board 5 is lowered, and then the integrated board 5 filled with bulk cargo is pushed into the conveying equipment. The integrated board 5 is transported into the security inspection area through the conveying equipment. The security inspection will conduct centralized security inspection and scanning of the bulk cargo on the integrated board 5. After passing the inspection, it will continue to be transported to the airport control area. After the staff in the control area unloads the bulk cargo, the empty integrated board 5 is returned to the chassis system of the modular and efficient bulk cargo transport trailer system through the conveying equipment. After the integrated board 5 is reset, the on-site staff will lift the baffle 6 to limit the integrated board 5, and then connect it to the traction rod 4 through the tractor and tow it to the cargo loading place to repeat the above work process. The trailer can also be connected to the traction rod 4 of car B through the tail hook 7 of car A to form multiple trailers moving synchronously.
