The hot water sprayed from the nozzle passes through the filter and enters into various areas. The seeds directly enter into the hot water in the area, and the hot water sticks to the filter before screening. When screening, the seeds can be preheated, and the temperature difference between the screening and soaking stages is prevented from being too large, thereby improving the survival rate of the seeds.

[0017] The present invention starts a driving motor after the seeds are output, and the driving motor drives the pulley system to rotate, and the pulley system drives the rotary pump to work, so that the hot water input by the water inlet pipe is input into the water delivery pipe, and then enters into the water storage pipe and is sprayed out through the nozzle.

The different cleaning and stirring blades can be continuously driven to rotate and the seeds therein can be turned over, which can not only improve the soaking effect, but also separate impurities and improve the seed cleaning effect.

[0019] The present invention fixes the cleaning and stirring blades because there are no seeds pressing the locking block during the cleaning process. In this way, the cleaning and stirring blades will not be driven to rotate during the rotation of the screen, and the cleaning surface is always raised, which cooperates with the water spray component to improve the cleaning effect, reduce the difficulty of cleaning the screen, and improve work efficiency.

[0020] The present invention cooperates with the projections on the screener and the cleaning and stirring blades to continuously drive different cleaning and stirring blades to rotate, and the stirring shaft also rotates accordingly, driving the disc to rotate. The disc, the guide rail, the slider, and the connecting rod form a system, so that the slider moves linearly in the guide rail, and the connecting rod drives the moving plate to continuously move, and cooperates with the cleaning and stirring blades to separate impurities. Due to their density, impurities and incomplete seeds will be above the soaking water, and the blades will push the impurities and incomplete seeds above and push them out through the impurity removal port, and the water spray component will also continuously add water, which can improve the seed cleaning effect, select high-quality seeds and improve the planting effect.

[0021] The present invention starts a driving motor, which drives the pulley system to rotate, which drives the driving shaft to rotate, and the driving shaft rotates the first filter, the second filter and the third filter. The seeds are first screened by the first filter to filter out the smaller seeds, and then the medium-sized seeds are filtered out by the second filter.
