Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model provides a technical solution: a corn high-quality seed quick screening device, including a support seat 1, a fixed caster 2, a screening box 3, a dispersion chamber 4, a feed inlet 5, a motor 6, a dispersion roller 7, an exhaust fan 8, a waste dust box 9, a dust suction pipe 10, a partition 11, a filter plate 12, a screen plate 13, a spring column 14, a fixed block 15, a motor 16, a rotating plate 17 and a collecting box 18, such as Figure 1 and Figure 3 As shown, fixed casters 2 are installed at the four corners of the lower surface of the support seat 1, and a screening box 3 is installed on the upper surface of the support seat 1. The support seat 1 supports and stabilizes the screening box 3. When the screening device needs to be moved, the brake pads above the fixed casters 2 are opened, and the screening box 3 is pushed. The fixed casters 2 assist in moving the screening box 3, and the screening device is moved to a suitable position. The brake pads above the fixed casters 2 are closed to prevent the screening device from being easily moved;

[0024] After the screening device is moved to a suitable position, a dispersion chamber 4 is installed at the upper end of the screening box 3, a feed port 5 is opened at the upper end of the dispersion chamber 4, a motor 6 is installed on the left side of the dispersion chamber 4, and a dispersion roller 7 is connected to the output end of the motor 6. The motor 6 is turned on, and the motor 6 drives the dispersion roller 7 to rotate. The surface of the dispersion roller 7 is equipped with dispersion blades, and the corn seeds to be screened are poured from the feed port 5 at the upper end of the dispersion chamber 4. The corn seeds enter the dispersion chamber 4, and the dispersion roller 7 and the dispersion blades scatter the corn seeds;

[0025] like Figure 2 and Figure 4 As shown, while the corn seeds are scattered, an exhaust fan 8 is installed on the right side of the screening box 3, and the rear side of the exhaust fan 8 is connected to a waste box 9 through an air duct. A dust suction pipe 10 is installed on the upper end of the waste box 9, and the end of the dust suction pipe 10 is installed on the right side wall of the dispersion chamber 4. A dust suction port is opened on the right side wall of the dispersion chamber 4. The exhaust fan 8 is turned on, and the exhaust fan 8 sucks the scattered corn crumbs and dust into the waste box 9 through the dust suction pipe 10. A partition net 11 is installed inside the dust suction pipe 10. The aperture of the partition net 11 is small, which can block the corn seeds from entering the dust suction pipe 10 to avoid wasting the corn seeds. A filter screen is installed inside the waste box 9. The filter screen can block dust and waste, prevent dust and waste from entering the exhaust fan 8, and avoid clogging the exhaust fan 8. The filter screen collects dust and waste, which is convenient for subsequent unified cleaning;

[0026] After the corn seeds are removed from the impurities, a filter plate 12 is installed below the dispersion chamber 4, and the corn seeds are screened through the filter plate 12. The corn seeds that meet the aperture pass through the filter plate 12 and enter the screening box 3. A screen plate 13 is installed inside the screening box 3. Spring columns 14 are installed at the four corners of the lower surface of the screen plate 13. A fixing block 15 is installed at the bottom end of the spring column 14. The corn seeds fall onto the screen plate 13 through the filter plate 12. The spring column 14 and the fixing block 15 support the screen plate 13.
