[0044] The working principle of the present invention is that when in use, water is first supplied to the water selection box 3 through the water supply mechanism 6, and the water surface is located in the water selection box 3, and then the tobacco seeds that need to be water-selected are put into the water selection box 3, among which a part of the shriveled seeds will float on the water surface, and most of the seeds will sink to the bottom of the water selection box 3. At this time, the stirring mechanism 7 in the water selection box 3 is used to stir the tobacco seeds underwater, so that the tobacco seeds in the water are initially separated, and the shriveled seeds are allowed to float to the water surface while the full seeds continue to sink to the bottom of the water. In addition, the seeds that sink to the bottom of the water can be kneaded by the separation mechanism 8, so that the shriveled seeds and the full seeds are thoroughly separated. The bottom of the water is separated, thereby avoiding the problem that the shriveled seeds stick to the full seeds and cannot float to the surface of the water, thereby improving the water selection effect of the tobacco seeds, so that the shriveled seeds and the full seeds can be accurately separated. After the water selection of the tobacco seeds is completed, the water supply mechanism 6 continues to inject water into the water selection box 3, so that the water surface is located in the cleaning box 4. At this time, the cleaning mechanism 10 is driven by the moving mechanism 9 to clean the shriveled seeds on the water surface in the cleaning box 4 to the discharge port 11 for discharge. The full seeds that sink to the bottom of the water selection box 3 can be obtained by opening the drain pipe 5 and filtering the water, and the use effect is better.
