AI Technical Summary
Technical Problem
Small stones and gravel that are easily mixed in with corn seeds are difficult to effectively screen, affecting the screening results.
Method used
A corn seed screening device was designed, which uses a bellows and a separator to separate corn seeds from stones. The seeds are deflected to the hollow area by wind power, while the stones remain in the solid area. The screening and discharge are carried out by a ramp and a guide plate.
Benefits of technology
This improved the screening effect, enhanced the assembly and flow guiding capabilities of the device, and ensured the purity and quality of the corn seeds.

Abstract
The utility model relates to the technical field of corn seed screening, and discloses a screening device for corn seeds, which comprises a fixed bottom plate and a screening box, one side of the top of the screening box is communicated and provided with a feed port, and a hollow area is formed on a partition plate and positioned on the right side of a baffle plate. The partition plate is fixedly installed at the upper position in the screening box, the top of the partition plate is divided into two areas, one area is the solid area, the other area is the hollow area, after an air bellow is assembled, the air feeder on the side edge is started to work to supply air, airflow is guided into the screening box through the circulating pipe after being filtered through the filter plate, and therefore the screening effect is achieved. Therefore, when feeding is conducted at the position of the feeding port, air flow blows corn seeds to shift rightwards to reach the position above the hollow area, particles such as stones with the gravity larger than that of the corn seeds are located above the solid area, and the materials flow out of the hollow area and are screened through the screening plate under guiding of the material guiding plate. In this way, the overall screening capacity is well improved in the working process.
