The invention discloses a self-lifting type sand baffle comprising a sandstorm baffle and a base. The self-lifting type sand baffle is characterized in that the front end of the base is connected with the sandstorm baffle, the rear end of the base is hinged to a vertical rod fixed to a foundation, and the position where the base and the vertical rod are hinged is 0.5 m away from the ground; a chain is connected between the vertical rod and the base; the two ends of the chain are connected to the middle of the vertical rod and the middle of the base respectively. The sandstorm baffle is two meters high, and the base is two meters long and two meters wide. The self-lifting type sand baffle has the advantages that the baffle is easy to install and fix, not only can be of a stable triangle structure facing a sandstorm to share the wind force, but also can protect the space, large enough to contain sand, below the base; as sand is prone to depositing at the hinged position, space large enough can prevent a large amount of sand from being easily stacked at the hinged position, and the sandstorm baffle is lifted rapidly; meanwhile, due to the fact that the hinged position is away from the ground by a certain distance, the sandstorm baffle can be lifted as high as possible.
