the driving motor 31 drives the first sprocket wheel 37 through the second sprocket wheel 38, the first sprocket wheel 37 drives the transmission gear 36 to rotate through the transmission shaft 35, the transmission gear 36 is meshed with the transmission toothed ring 22, the transmission toothed ring 22 drives the rotary net drum 23 to rotate, the rotary net drum 23 drives the entering grains to centrifugally rotate, hot air flow sprayed by the air spraying holes 15 is received, the grains are quickly dried by the hot air flow, and water vapor carrying the surfaces of the grains is discharged through the exhaust screen 34.
Embodiment two:
on the basis of the first embodiment, the air spraying holes 15 are omitted, so that the directional air guide plate 14 is directly connected with the outside, and meanwhile, the connection position of the directional air guide plate 14 is changed to the top end of the protective sleeve 10, and the discharge of water vapor is quickened.
A plurality of heat conducting rods are welded on the outer wall of the protective sleeve 10 at equal intervals, one end of each heat conducting rod passes through the protective sleeve 10 and is positioned between the electric heating net drum 11 and the drying net drum 25, the other end of each heat conducting rod passes through the mounting sleeve 12 and is positioned in the rotary net drum 23, and grains are contacted with the heat conducting rods, so that the drying speed is increased; and an exhaust fan is additionally arranged on one side of the exhaust screen 34 to accelerate the flow speed of the air flow.
Embodiment III:
on the basis of the first embodiment and the second embodiment, the cooling fan structure is additionally arranged at the top end of the guide hopper 19, so that the cooling speed of the grains after drying is accelerated, the temperature of the grains is reduced, the grains are convenient to transport and store, long-time accumulation is avoided, the heat dissipation speed of the grains is low, the heat accumulation condition occurs, and unnecessary loss of the grains is caused.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
