The invention relates to the field of dump trucks and provides a dumping device for a truck. The dumping device comprises a cargo loading carriage and a lifting mechanism, wherein a discharging opening is formed in the rear part of the cargo loading carriage; the cargo loading carriage is arranged on a truck body and is hinged to the truck body through lifting lugs at the rear part of the cargo loading carriage; the lifting mechanism comprises a driving mechanism, a rocking bar and connecting rods; the rocking bar is hinged to the truck body through a first hinge point arranged at one end of the rocking bar and is hinged to the connecting rod through a second hinge point arranged at the other end of the rocking bar; the connecting rods are hinged to the cargo loading carriage through third hinge points arranged on the connecting rods; the driving mechanism acts on the first hinge point of the rocking bar, so that the rocking bar rotates relative to the first truck body at the first hinge point, and the turning of the cargo loading carriage is realized; a material retaining plate is connected to the rear part of the connecting rod; when the cargo loading carriage turns, the discharging opening is automatically opened by the material retaining plate, and the dumping process of cargoes is realized. The dumping device disclosed by the invention is simple in structure and easy for maintenance; the turning of the cargo loading carriage is realized by a four-link mechanism. Compared with linear motion of a traditional hydraulic rod, the motion mode disclosed by the invention has the advantage that insufficient strength caused by overlong extension of a piston rod is overcome.
