DETAILED DESCRIPTION
[0012] The utility model will be further explained in connection with the drawings.
[0013] For example Figure 1The device for removing impurities from corn seeds for seed production includes a winnowing box 1 and a vibrating screen 3. The winnowing box 1 is fixedly connected with a feeding port 7 at the top of one side. A conveying belt 2 is arranged above the vibrating screen 3 to convey the corn seeds after threshing to the vibrating screen 3. The vibrating screen 3 is connected with a first collecting box 4 at the bottom to collect small-volume impurities screened by the vibrating screen 3. A feeding hopper 5 is arranged below the output end of the vibrating screen 3. The feeding hopper 5 is fixedly connected with an auger 6 between the feeding hopper 5 and the feeding port 7 to facilitate the conveying of corn seeds to the feeding port 7. The feeding port 7 is fixedly connected with a first air lock 8 at the bottom. The winnowing box 1 is fixedly connected with a second air lock 12 at one side of the bottom and a third air lock 13 at the other side of the bottom. The first air lock 8, the second air lock 12 and the third air lock 13 serve to unload and lock air. The feeding port 7 corresponds to the position of the second air lock 12 to facilitate the falling of the winnowed corn seeds into the second air lock 12.
