The invention discloses a transport van. The transport van comprises a frame, a compartment body located above the frame, a hopper arranged at the bottom of the compartment body, a movable base platelaid on a bottom transverse beam of the compartment body, and a driving device arranged on the frame, wherein the movable base plate can move relative to the bottom transverse beam at the bottom of the compartment body, the movable base plate comprises at least two sub-base plates, the sub-base plates are connected through a hinge shaft, the top end of the driving device is connected with the hinge shaft of the movable base plate, the hinge shaft is driven by the driving device to drive the movable base plate to move upwards from the bottom plane of the compartment body so that the sub-base plates on the two sides of the hinge shaft get close to the middle, and a gap is formed between the movable base plate and the side wall of the compartment body. The transport van can meet the requirement for multiple purposes of a market grain transport van, and the grain unloading efficiency is improved.
