Description

Technical Field

[0001] The utility model relates to the technical field of river channel cleaning, in particular to a rice seed screening device. Background Art

[0002] Rice is one of the important food crops of mankind. It has a very long history of cultivation and consumption. Half of the world's population eats rice, mainly in Asia, southern Europe, tropical America and parts of Africa. The total output of rice ranks third in the world's food crop output, lower than corn and wheat, but can sustain the lives of a larger population. Before rice planting, seed selection begins after drying the seeds. Seed selection mainly involves selecting high-quality seeds and removing inferior seeds, so that after sowing, the seedlings can grow strong and neat. Clean water can be used to select seeds. First, soak the seeds in water. The seeds will sink after absorbing water, while the empty shelled seeds will float. In this way, high-quality seeds with full grains can be selected to increase the germination rate.

[0003] After searching, the patent number is CN217165243U, which discloses a rice seed screening and impurity removal device. The second filter screen is driven to vibrate by the screening base, so that large rice seeds are retained in the second filter screen, and the large rice seeds are discharged through the second material nozzle. At the same time, the small rice seeds that pass through the second filter screen will be discharged through the first material nozzle. By setting the splicing frame and the second filter screen, the impurity removal device has a multiple screening structure to improve its use effect. However, when in use, dust and empty rice grains in the rice can pass through the filter screen at the same time as the rice seeds in the screening process, affecting the quality of the rice seeds. At the same time, the screened rice seeds need to be further screened out to find full seeds, which increases the screening steps and reduces the screening efficiency.

[0004] Therefore, a rice seed screening device is proposed. Utility Model Content
