[0002] With the development of modern agricultural science and technology, advanced grain production technology has been promoted and applied in rural areas. However, the increased grain production needs to be safely stored. The key to safe storage of grain is to reduce the moisture content in the grain to reduce the occurrence of mildew. At present, some grain depots and grain processing plants in my country have changed from the traditional method of artificial drying to reduce the moisture content in grain to mechanized drying. The outstanding advantage of mechanized drying is that it is not restricted by natural conditions and can be operated around the clock.

[0003] At present, in the process of drying grain, it is not convenient to filter the dust and impurities mixed in the grain well, so that a large amount of straw, stone, dust and other impurities easily affect the subsequent processing and are inconvenient to use. Therefore, the utility model provides an air supply and dust removal device for grain drying. Utility Model Content
