Multifunctional geographic sunshine projection teaching experiment device

The invention belongs to the technical field of teaching devices, and particularly relates to a multifunctional geographic sunshine projection teaching experiment device. The device comprises a base,a sun model and an earth model; a longitudinal supporting rod is fixedly installed on the base; a rotatable earth motion orbit is installed on the longitudinal supporting rod; the shape of the earth motion orbit simulates the orbit shape of the earth moving around the sun; the sun model comprises a light scattering and emitting body, a longitudinal rotating ring, a transverse rotating ring, a linear light source and a light source supporting column; the earth model is installed on the earth motion orbit in a sliding mode; and the earth model not only can slide along the earth motion orbit, butalso can simulate real earth rotation. According to the device, not only the real process that the earth moves around the sun, but also the sunshine projection can be simulated; and the three-dimensional and dynamic effects a
