In the present utility model, the outer periphery of the drum 4 can be wrapped with a fixed heat-preservation cover cylinder 10, which plays a role of heat preservation. In order to ensure that the heated and dried grains are slowly dissipated and then sent out, a fixed heat dissipation cylinder 11 can be provided on the side corresponding to the heating source 3 and below the closed drum 4, and a spiral heat dissipation auger 12 is also provided in the heat dissipation cylinder 11. The heat dissipation auger 12 is opposite to the rotation direction of the auger 8 in the drum 4, and the discharge port at the end of the drum 4 is connected to the feed port at the corresponding end of the heat dissipation cylinder 11 through a material passing plate, and the lower end of the heat dissipation cylinder 11 is provided with a discharge port 13 .

The transmission structure of the drum 4 and the auger 8 of the utility model and the heat dissipation auger 12 in the heat dissipation cylinder 11 is that the power motor 9 is fixed on the frame 1, and it is connected with the small by the upper chain wheel 14 and the upper chain 15 thereof. The gears 16 are connected, the upper sprocket 14 and the pinion 16 are installed on the same upper short shaft 17, the pinion 16 is meshed with the reversing deceleration large gear 18, and the reversing deceleration large gear 18 is installed on the side of the auger 8 in the drum 4 On the extension end of rotating shaft 6; power motor 9 links to each other with small sprocket 21 by lower sprocket 19 and its lower chain 20 simultaneously, and lower sprocket 19 and small sprocket 21 are installed on the same lower short shaft 22, and small sprocket 21 Link to each other with the deceleration large chain wheel 24 that is fixed on the outer wall of cylinder 4 corresponding positions by chain 23; The small transmission gear 26 is meshed, and the small transmission gear 26 is installed on the extending end of the rotating shaft of the heat dissipation auger 12 in the heat dissipation cylinder 11 .

In the utility model, the rotating shaft 6 of the auger 8 in the closed drum 4 can be a hollow rotating shaft, and a plurality of small air holes 35 are arranged on its outer wall, and its tail end is connected with the hot air pipe 36 through a movable joint. A suction fan 27 is provided, and its end is connected with the heating source 3 . The heating source 3 is also connected to the lower part of the feed bin 5 through the hot and cold air pipe 28, and the hot and cold air pipe 28 is provided with a suction fan 29, a hot air control valve 30 and a cold air control valve 31.
