Zusammenfassung:	The utility model discloses a light source mechanism and relates to the technical field of grain detection. The light source assembly is used for illuminating rice and comprises a front light source and a back light source which are arranged up and down; the shading assembly and the light source assembly are combined to form a dark field light source mechanism, and the shading assembly comprises a shielding plate, a diffusion plate and a driving mechanism used for driving the shielding plate and the diffusion plate to rotate to the position between the front light source and the back light source; the driving mechanism comprises two driving frames which are symmetrically arranged and two driving motors which are symmetrically arranged on one sides of the driving frames up and down, and the two driving frames are located on the two sides of the light source assembly correspondingly. Compared with a detection mode of a single light source, the light source assembly is matched with the shading assembly to form a
