[0036] Refer Figures 3 - 4 As shown in the figure, the dust collection mechanism 3 is arranged above the seed screening box 1. It is convenient to collect the flying dust in the support and dispersion barrel 101 through the dust collection mechanism 3. The dust collection mechanism 3 includes a barrel cover 301, and the barrel cover 301 is buckled above the support and dispersion barrel 101. The barrel cover 301 plays a role in buckling and closing the support and dispersion barrel 101, reducing the situation where internal dust and other impurities in the support and dispersion barrel 101 fly into the environment during use.

[0037] Refer Figure 3 As shown in the figure, a feeding pipe 304 is fixedly connected above the barrel cover 301. It is convenient to add the crop seeds to be screened into the support and dispersion barrel 101 through the feeding pipe 304.

[0038] Refer Figure 3 As shown in the figure, a pair of moving handles 305 are arranged on one side of the feeding pipe 304, and both of the pair of moving handles 305 are fixedly connected to the barrel cover 301. By applying a force to the pair of moving handles 305, the barrel cover 301 can be moved and held. This simplifies the convenience of disassembling and assembling the barrel cover 301.

[0039] Refer Figures 3 - 4 As shown in the figure, a dust discharge pipe 302 is arranged on one side of the barrel cover 301. The flying dust and other impurities in the support and dispersion barrel 101 are guided and transported through the dust discharge pipe 302. A dust collection filter bag 303 is fixedly connected to the end of the dust discharge pipe 302 far from the support and dispersion barrel 101.
