The invention discloses an automatic lifting dumper rear lower portion protection device, and belongs to the field of dumper rear protection devices. The device comprises an anti-collision beam assembly, a mounting plate assembly, an electric push rod assembly, a radar velocimeter, a control system, an operation display and a driving system. The anti-collision beam assembly is used for protecting the driving safety of the dumper and rear vehicles, the mounting plate assembly is used for connecting the tail end of a frame and mounting the anti-collision beam assembly and the electric push rod assembly, the electric push rod assembly is used for providing rotation power for the anti-collision beam assembly and collecting pressure signals, and the radar velocimeter is used for measuring the vehicle speed. The control system is used for controlling lifting and following movement of the electric push rod assembly. The operation displayer is operated by a driver. The angle and the height of the rear protection device of the dumper can be changed by controlling the lifting of the electric push rod, the departure angle and the tail space of the dumper are increased, and the safety protection effect is achieved while the special operation requirements are met.
