The outer wall of the box body 1 is fixedly provided with a protective cover 9, and the motor 61, the driving wheel 62, the three driven wheels 63, the upper driving wheel 7, the lower driving wheel 8 and the closed transmission belt 64 are all positioned in the protective cover 9, so that a good protective effect is achieved, and the phenomenon that the closed transmission belt 64 is derailed due to the action of external force is favorably prevented. In addition, the probability of accidents caused by the fact that a worker accidentally touches the motor 61, the driving wheel 62, the three driven wheels 63, the upper driving wheel 7, the lower driving wheel 8 and the closed driving belt 64 in operation is reduced, and safety is improved.

For the operation of facilitating the cereal work of unloading, the diapire is fixed with guide block 10 in the box 1, baffle box 101 has been seted up to guide block 10 upper surface, guide block 10 upper surface and baffle box 101 all incline towards ejection of compact pipe chute 12 one side, and the opening that baffle box 101 is close to solenoid valve 121 one end communicates with ejection of compact pipe chute 12, the cereal after the drying is accomplished drops to the baffle box 101 of guide block 10 in to this cereal after the drying is discharged by ejection of compact pipe chute 12.

The use principle of the embodiment is as follows: when using, the staff can transport the cereal of treating drying to the loading hopper 11 through the flood dragon conveyer in, and the cereal gets into box 1 and hits turning over board 22 from loading hopper 11, and turning over board 22 rotates around last live-rollers 21 to this makes cereal obtain the dispersion, and on the one hand, going up behind axial fan 31 work, blow towards collection thing box 32 one side, has accelerateed the heat that first heating member 13 produced and has flowed in box 1, is favorable to the cereal drying. On the other hand, go up axial fan 31 work back, will blow upward album thing box 32 from flat millet in the cereal that upper turnover panel 22 dropped and dust etc. is favorable to flat millet and dust to get into and go up album thing box 32 to the staff concentrates the clearance, has reduced debris and flat millet content in the cereal, has improved the cereal quality. The motor 61 drives the driving wheel 62 to rotate forward after working, under the transmission action of the closed transmission belt 64, the upper driving wheel 7 rotates forward, the lower driving wheel 8 rotates reversely, so that the rotating directions of the upper turning plate 22 and the lower turning plate 43 are opposite, the falling speed of grains in the box body 1 is reduced, the time that the grains are retained in the box body 1 is prolonged, and the full drying of the grains is facilitated. Simultaneously, downside paving subassembly 5 leans on ejection of compact pipe chute 12 one side to rotate from driving wheel 63 forward, and well side paving subassembly 5 keeps away from ejection of compact pipe chute 12 one side from driving wheel 63 antiport, and upside paving subassembly 5 leans on ejection of compact pipe chute 12 one side also to rotate from driving wheel 63 forward to make upper and lower adjacent closed conveyer belt 53 antiport, be favorable to prolonging time and the distance that cereal carried in box 1, and then improve the dry effect of cereal.
