Description

Technical Field

[0001] The utility model relates to the technical field of soybean local variety screening, in particular to a soybean local variety screening device. Background Art

[0002] Soybeans are harvested, threshed, and stored mechanically in the field all at once. This process can introduce debris such as soil, stones, stems, leaves, and husks, leading to high seed impurities and poor sowing quality. Harvested seeds can also include shriveled or damaged seeds, making them slow to germinate or non-emerge, resulting in low survival rates and negatively impacting crop returns. Seed processing removes these impurities to preserve only the highest-quality seeds.

[0003] For example, a soybean threshing and screening device with the authorization announcement number CN221615614U is provided in the above document through the setting of a handle, a storage frame, and a first screening net.

The connecting rod 1 204 and the connecting rod 207 drive the guide frames 206 on both sides to move back and forth through the corresponding sliders 205. The guide frames 206 drive the screen 301 to move back and forth, so that the screen 301 drives the top soybeans to move horizontally. At the same time, the screen 301 drives the support rod 30 3 reciprocates. During the reciprocating movement of the support rod 303 along the guide seat 305 via the pulley 304, the screen 301 is affected by the spring 302, causing the screen 301 to move up and down, causing the soybean seeds on the top of the screen 301 to move up and down, thereby screening the soybeans. The upper screen 301 is used to screen larger impurities and soybeans, and the lower screen 301 is used to screen small impurities and shrunken beans. The screened impurities are discharged through the discharge port 102. By removing the baffle 4, the high-quality soybean seeds screened on the lower screen 301 are taken out through the material taking port 103.
