TECHNICAL FIELD
[0001] The present application relates to the technical field of grain drying, in particular to a grain drying equipment with dust and impurity removing functions. BACKGROUND
[0002] In order to avoid the mildewing of the grain, the grain needs to be dried by using a drying equipment. Since the grain is mixed with impurities and dust during the harvesting process, the grain needs to be screened to remove the impurities and dust before drying to ensure the quality of the grain. However, the existing drying device does not have a screening function and needs to be additionally operated by using a screening equipment, which is inconvenient and complicated. In addition, the existing drying equipment does not have a stirring function during the drying process, which causes the grain at the bottom to be unevenly heated. If the drying time is increased, the grain on the outside is easily over-dried and the time is consumed. If the drying time is short, the grain on the outside is already dried while the grain inside is not dried, which makes the drying effect of the grain poor. SUMMARY
