Description

Technical Field

[0001] This utility model relates to the field of corn screening technology, specifically a corn seed pellet screening machine. Background Technology

[0002] Corn seeds are the reproductive organisms capable of growing into mature corn plants. They are formed from ovules through pollination and fertilization. A corn seed consists of three parts: the seed coat, the embryo, and the endosperm. Corn seeds are classified into four types: conventional varieties, inbred lines, single-cross varieties, double-cross varieties, and triple-cross varieties. Different types of corn seeds vary in physical characteristics such as size, shape, and weight, requiring screening to ensure seed quality and planting effectiveness. Corn is an important food and feed crop worldwide, widely cultivated globally. The massive scale of corn cultivation creates a huge demand for corn seeds, providing a vast market for corn seed pellet screening machines. Seed quality is a key factor affecting corn yield and quality. To improve corn yield and quality and ensure food security, the market demands increasingly higher quality corn seeds. Seed producers and growers urgently need equipment that can improve the accuracy and efficiency of seed screening.

[0003] The existing technology has the following shortcomings: The existing technology, application number CN202021592150.3, describes a corn seed pellet screening machine, including a machine body.
