[0002] After harvesting, grains need to be dried to remove a certain amount of moisture and keep the grains dry for better storage. When drying grains, in order to make the grains evenly exposed to sunlight, the grains need to be turned over frequently, and the grains on the lower layer need to be turned over to the upper layer. However, most existing grain turning and drying machines use bamboo rakes or iron rakes, which not only fail to completely turn the grains, but also require a lot of effort to hold for a long time, resulting in a time-consuming and labor-intensive process of turning the grains over and over, and inconvenient use. Therefore, a grain turning and drying machine is designed. Summary of the invention
