Description

Technical Field

[0001] The utility model relates to the field of seed cleaning, in particular to a seed cleaning device. Background Art

[0002] With the development of modern agriculture, the requirements for seed quality are getting higher and higher. As the basis of agricultural production, the quality of seeds directly affects the yield and quality of crops. However, during the planting, harvesting, storage and transportation of seeds, they are often contaminated with various impurities such as dirt, dust and microorganisms. These impurities will not only reduce the germination rate of seeds, but also cause bacteria infection, affecting the growth and yield of crops. Therefore, the application of seed cleaning devices is particularly important. It has become an essential equipment to improve seed quality and ensure agricultural production efficiency.

[0003] There are many obvious deficiencies in the existing seed cleaning technology. First, the seed cleaning device can easily damage the seeds during the cleaning process. Common cleaning methods may cause damage to the seeds due to improper mechanical stirring or excessive water impact, such as scratches and breakages. These damages not only affect the appearance of the seeds, but more importantly, they will reduce the germination rate and quality of the seeds, and have an adverse effect on subsequent planting and yield. Secondly, most cleaning devices lack grading and screening functions and cannot distinguish seeds of different sizes and qualities, which is not conducive to subsequent precision planting and cultivation.

[0004] Therefore, in view of the problem that the above-mentioned existing cleaning devices are easy to damage seeds and lack grading, screening and coating functions, a seed cleaning device can be designed to reduce damage to seeds, and add grading, screening and coating functions, to grade and screen seeds, and provide protection and nutritional supplements for seeds in time after cleaning.
