A grain drying device convenient to use, comprising a drying device body (1). Two symmetrical sleeves (12) are fixedly embedded in the inner top wall of the drying device body (1). A support plate (7) is fixedly connected inside the drying device body (1), and the support plate (7) divides the drying device body into a device chamber (5) and a drying chamber (10). A first bearing (3) is fixedly embedded in the middle of the support plate (7). The device chamber (5) is located below the drying chamber (10). The middle of the inner bottom wall of the device chamber (5) is fixedly connected to a first motor (4). An output end of the first motor (4) is fixedly connected to a first rotating shaft (2). The grain drying device convenient to use ensures effective contact between grains and heat in a drying cage, more uniform heating of the grains and a good drying effect, effectively avoids baking of the grains by a heat source, effectively accelerates the flow velocity of heat, effectively avoids burnt grains, effec
