The tail board of the container of the dump truck in the prior art has the following problems: (1) When the goods are loaded, large materials are smashed to the tail plate of the container, and the inner side of the flat plate of the tail plate is damaged due to the fact that the materials are smashed. (2) When the dump truck is fully loaded, the tail plate is subjected to larger extrusion force of goods in the container, and the tail plate is easy to deform backwards and expand outwards. (3) When unloading, the front part of the container is lifted, the goods quickly impact the tail plate, and especially when the goods are large stones, huge impact force causes the hollow and uneven tail plate, and when serious, the rear transverse and vertical reinforcing ribs are cracked and even damaged. (4) In the lifting and unloading process of the front part of the container, the tail part of the dumper is gradually close to the ground, and the lower part of the tail plate can be blocked by unloaded cargos and damaged by extrusion. (5) If the dump truck is sunk into a mud pit and needs to be pushed forwards by a machine such as an excavator or a forklift, the tail plate of the cargo box is easy to deform and damage under the action of the external force. (6) The two sides of the upper part of the tail plate are hinged with the hook seats on the left side plate and the right side plate of the cargo box, the two sides of the lower part of the tail plate are connected with the manual hooks on the two sides of the bottom plate of the cargo box, and the tail plate is easy to damage at the four stress concentration points; (7) When goods are loaded, materials are easy to accumulate on the transverse and vertical ribs at the rear side of the tail plate, and when a vehicle runs, the accumulated materials fall, scatter and fly, so that the road surface and the environment are polluted; (8) The contact position of the inner side of the tail plate and the side plate and the bottom plate of the container is not tight, and if the goods are particles or powder, the goods easily leak from the joint of the tail plate and the side plate and the bottom plate of the container, so that the road surface and the environment are polluted, and the safety of pedestrians is threatened.
