Background

Agriculture is the foundation of national economy since ancient times, and China always explores the way of agricultural development and obtains great achievements in agricultural science and technology, economy and various aspects in order to realize the soaring of the economy and the improvement of comprehensive strength in China. However, the existing Chinese agriculture has problems in the aspects of society, economy, ecology and the like, the development of agriculture is severely restricted, the development of agriculture in China must determine a definite target, an agriculture development mode suitable for the actual situation in China is selected, and the modernization of agriculture is finally realized. In addition, the prices of raw materials and agricultural products are increased, the prices of fertilizers, greenhouse films and diesel oil are obviously increased in the past few years, and the cost of agricultural production is increased. Although the price of agricultural products is also increased, the government takes certain control measures for the price increase of terminal agricultural products because the agricultural concern is about the eating problem of hundreds of millions of people, and certain negative effects are generated on the overall profit level of agriculture. Particularly, in some hilly areas, the land area is small, the release is diffused, large-scale machines are difficult to intensively develop, the harvested grains are few, gravel, flat grains and the like are contained in the grains, the large-scale machines are not cost-effective, and the cost is high.

The existing equipment cannot completely separate gravel, rice hulls and the like doped in grains, and a plurality of devices are needed.
