The utility model provides a bed load bed surface particle shooting device comprising a transparent plate (1), waterproof bars (2) and four suspension parts (3); two ends, in the length direction, of the transparent plate (1) are provided with gradual change arc structures that warp up; two ends, in the width direction, of the transparent plate (1) are provided with the waterproof bars (2), and each of four corners of the transparent plate (1) is provided with a suspension part (3) used for adjusting the height of the transparent plate (1). According to the bed load bed surface particle shooting device, the transparent plate is arranged on a water flow, the transparent plate is enabled to gradually contact with the water flow below the transparent plate, interference caused to images by water surface ripples can be eliminated, and flatness of a shooting plane is ensured; when the water flow is in rapid stream state or flows at large speed, images of accurate bed surface sand grain positions at different momen
