Description

Technical Field

[0001] The utility model relates to corn seed grain screening equipment and belongs to the technical field of corn seed grains. Background Art

[0002] Corn kernels are the seed part of the corn plant, usually yellow or white, and oblate in shape. The kernels are rich in starch, protein, and a small amount of fat, and are important food and feed resources. The outside of the kernel has a hard seed coat, which contains the embryo and endosperm, which provides the nutrients needed for seed germination. Corn kernels need to be screened before processing to ensure seed quality and germination rate. Screening can remove pests, damage, and unfull kernels, retaining healthy, full, and uniformly sized seeds, which helps improve seed germination ability and seedling growth potential. At the same time, screening can also remove impurities and other non-seed materials, ensure high seed purity during planting, reduce the risk of weeds and pests, and thus increase corn yield and quality. Screened kernels can perform more stably under different growth conditions, ensuring the success of agricultural production.

[0003] Authorization announcement number (CN218309246U) discloses a corn seed screening device, which belongs to the technical field of agricultural equipment. The corn seed screening device comprises a box body, a feeding device is arranged on the top of the box body, a screening device is arranged inside the box body, and the screening device is used to screen out impurities in corn seeds; a storage box is also arranged on the bottom wall inside the screening device; an anti-blocking device is arranged on the top of the screening device, and the anti-blocking device is used to clean the screening device; the anti-blocking device is movably connected to the screening device through a rolling connection mechanism; the anti-blocking device is a hollow cylinder, and a plurality of rows of protrusions and air outlets are arranged on the side wall of the anti-blocking device at equal intervals in the circumferential direction, and a rotating motor and a blower are arranged inside the anti-blocking device; the utility model can solve the problem that the filter screen of the existing screening device will be blocked by impurities and the screening effect will be reduced when the existing screening device is used for a long time;

The bottom of the storage box 14 The first motor 501 is located on the inner side of the protective cover 18, and the bottom plate 1 is fixedly mounted with positioning bolts 19 on all sides of the surface of the bottom plate 1. The lower ends of the positioning bolts 19 penetrate through the bottom plate 1 and extend to the bottom of the bottom plate 1.

[0033] By setting the block 6, the second spring 8 and the baffle 9, the screening basket 3 can be easily dismantled for maintenance or replacement. By setting the second motor 11 and the blades 12, the seeds on the inside of the screening basket 3 can be continuously turned over to ensure that the seeds can move to the surface of the screening mesh 4.
