At the same time, the device can change the number of sieve plates 11 according to customer needs, improving the practicality of the device.

[0028] As Figures 4-6As shown in the figure, the utility model provides a technical solution: Preferably, two rotating shafts 21 are fixedly connected to the left and right sides of the inner wall of the machine body 1. The side surface of the rotating shaft 21 is rotationally connected to the machine body 1. The upper end of the movable column 20 is movably connected to the material receiving plate 16. One end of the rotating shafts 21 close to each other is fixedly connected to a connecting plate 22.

The first motor 2 drives the rotating shaft 21 to rotate. The rotating shaft 21 drives the connecting column 25 to rotate. The connecting column 25 drives the transmission column 26 to perform a reciprocating motion, thereby driving the movable column 20 to perform a reciprocating motion. The movable column 20 contacts the material receiving plate 16, causing the material receiving plate 16 to vibrate. The material receiving plate 16 drives the support columns 18 to vibrate the sieve plate 11, facilitating the screening of the seeds on the screening mesh 12. The second motor 9 drives the threaded rod 10 to rotate. The rotation of the threaded rod 10 drives the moving plate 15 to move, dispersing the seeds at the top and improving the screening efficiency of the device. The screened seeds will fall on the material receiving plate 16. Turn on the fan 7 through the controller 3. The fan 7 starts and blows the seeds on the material receiving plate 16 into the discharge pipe 6.
