Description

Technical Field

[0001] This utility model relates to the field of seed coating technology, and in particular to an automated seed coating machine. Background Technology

[0002] Seed coating is a technique that uses adhesives or film-forming agents to coat the seeds with fungicides, insecticides, and some non-seed materials, forming a smooth and strong protective film. The insecticides and fungicides in the seed coating can effectively prevent seed-borne pathogens, soil-borne pathogens, and underground and above-ground pests, reducing the damage of diseases and pests to seeds and seedlings. The micronutrients and plant growth regulators in the coating provide necessary nutrients and regulatory substances for seed germination and seedling growth, promoting root development, dark green leaves, and vigorous seedling growth. For small and irregular seeds, pelleting treatment can increase seed volume and make them more uniform in shape and size, which is beneficial for mechanized sowing. In addition, the smooth surface of coated seeds can ensure even sowing during sowing and improve sowing quality.

[0003] Seed coating significantly improves seed quality and field performance after sowing. It effectively reduces pesticide use, lowers environmental pollution from agricultural production, reduces pest and disease damage to crops, ensures stable crop yield growth, and ultimately safeguards food security to meet the ever-increasing societal demand for food. It also improves seed emergence uniformity and seedling vigor, reduces manual replanting and thinning, lowers agricultural production costs, and increases efficiency. However, current seed coating machines struggle to ensure even coating of each seed. Furthermore, seed coating requires manual pouring of seeds into the equipment, and seed removal after coating is inconvenient and time-consuming, prolonging the entire coating cycle and reducing work efficiency. Utility Model Content
