The utility model relates to the technical field of rice screening, and discloses a quantitative screening device applied to rice. In the embodiment of the invention, the quantitative groove is formed in the bottom of the screening box, the cylindrical roller is arranged in the quantitative groove, and the material distribution groove is formed in the cylindrical roller, so that rice in the screening box can enter the quantitative groove in the process that the cylindrical roller is driven by the driving device, and the rice is separated from the screening box along with rotation of the cylindrical roller; the rice contained in the quantitative groove falls onto the conveying belt machine, and the volume of the quantitative groove is equal to that of the rice. In the slow rotation process of the cylindrical roller, the quantitative groove continuously conveys quantitative rice to the conveying belt machine, and therefore rice weighing and storing equipment is omitted, and the rice can be directly bagged throu
