Description
Technical Field
[0001] The utility model belongs to the technical field of seed selection devices, and particularly relates to a seed selection device. Background Art
[0002] In order to improve the seed quality, promote the growth, development and yield of crops, prevent diseases and pests, meet the environmental requirements, increase the germination rate and improve the economic benefits, seed selection is needed; seed selection can remove shriveled grains, small grains, broken grains, seeds with diseases and pests and various sundries, and select large, plump and uniform high-quality seeds to improve the overall quality of seeds.
[0003] Existing seed selection devices mainly include pneumatic selection, screening and liquid density separation. Pneumatic selection means using wind force to remove smaller and lighter seeds and retain heavier and larger seeds. Screening means using sieves with different apertures and shapes to screen and remove inclusions in the seeds. Liquid density separation means separating seeds through liquid density differences, which is applicable to seeds with large density differences. However, in the actual operation process of existing equipment, a single method is used to select seeds, resulting in poor seed screening effect and incomplete screening, which limits the application range of seed selection equipment. Content of the Utility Model
[0004] The purpose of the utility model is to provide a seed selection device that uses multiple methods to screen seeds simultaneously.
[0005] The described seed selection device includes a vertically arranged box body, and an inlet component, a pneumatic selection component, a filtering and screening component and a water storage component are sequentially arranged in the box body from top to bottom;
[0006] The inlet component includes an inlet box, the right end of the inlet box is fixed to the inner side wall of the box body, and an outlet is arranged at the left end;

Start the cross-flow fan to blow the lighter impurities and seeds into the first collection box through the feed hole on the left side wall of the first collection box, and take out the first collection box from the right side of the box body through the first through hole for cleaning; the heavier seeds fall downward along the channel into the first filter plate for filtering and then fall into the third storage box from the right side of the first filter plate. The filtered impurities and seeds fall into the second collection box along the guide plate; add the selected screening liquid into the third storage box. The unqualified seeds are lighter and will float. After the water is full, they overflow from the second slag outlet, thereby taking out the unqualified seeds and floating impurities from the third storage box. The seeds at the bottom of the third storage box are the qualified seeds after screening; through the screening of the air separation component, the filtering and screening component, and the water storage component, three different screening methods are carried out simultaneously, and the qualification rate of the screened seeds is high.
[0011] Further, there are two groups of the filtering and screening components. The filter plate of the other group of filtering and screening components is the second filter plate. The second filter plate is inclined with the left end lower and the right end higher and is arranged below the first filter plate. The right end of the second filter plate is connected to the right side wall of the box body, and the left end is independently located inside the box body.

[0026] The water pump pumps the liquid in the water storage box from the end of the water pipe located inside the box body into the third storage box, thereby recycling the liquid flowing from the bottom of the fourth storage box into the water storage box. After the screening is completed, the liquid in the water storage box can also be centrally treated, which is more resource-saving.
[0027] Further, a water outlet is provided at the bottom of the third storage box, and a third through hole communicating with the inside and outside is provided on the bottom wall of the box body corresponding to the water outlet.

The filtered impurities and seeds fall into the second collection box along the guide plate; add the screening liquid into the third storage box. The unqualified seeds are lighter and will float. After the water is full, they will overflow from the second slag outlet, thus taking out the unqualified seeds and floating impurities from the third storage box. The seeds at the bottom of the third storage box are the qualified seeds after screening; through the screening of the air separation component, the filtering and screening component and the water storage component, the screening is carried out by three different screening methods at the same time, and the qualified rate of the screened seeds is high.
