Turning up crops: when the plurality of air outlet pipes 37 are matched to blow and dry crops, the servo driver 25 is started, the operation of the servo driver 25 can drive the force transmission part to be matched with the belt transmission to drive the round rod 27 to rotate together with the transmission rod 28, and then the turning shovel 39 is driven to rotate through the corresponding bracket 38, so that the crops at the bottoms of the first drying cylinder 30 and the second drying cylinder 31 are shoveled into the corresponding turning shovel 39 and move together with the turning shovel 39;

the round bar 27 and the transmission bar 28 rotate through the cooperation of the two bevel gears 48 and the corresponding bevel gears 47 and 50 to drive the two rotating shafts 49 to rotate, and the rotation of the rotating shafts 49 drives the corresponding round bar and rack to rotate (the rotation directions of the two rotating shafts 49, the round bar 27 and the transmission bar 28 are opposite);

when the racks are meshed with the corresponding parallel shaft gears 44 (the racks are not contacted initially, the racks are contacted with the parallel shaft gears 44 and meshed after rotating by a certain angle), the two rotating rods 41 rotate, the rotating rods 41 pull the corresponding cover plates 40 upwards (in the direction shown in fig. 12) through the matching of the corresponding winding rods 42 and the traction ropes 43, when the two cover plates 40 continuously move upwards, crops in the two turner pieces 39 scatter downwards under the action of self gravity, when the two racks rotate away from the corresponding parallel shaft gears 44, the two cover plates 40 stretch the corresponding plurality of elastic telescopic rods under the action of elastic potential energy released by the corresponding plurality of elastic telescopic rods (in the upward moving process of the two cover plates 40), and then the two cover plates 40 apply reaction forces to the corresponding winding rods 42 and the corresponding rotating rods 41 through the corresponding traction ropes 43, so that the two rotating rods 41 and the corresponding winding rods 42 rotate and reset;

and because the rotation directions of the round rod 27 and the transmission rod 28 and the two rotating shafts 49 and the two racks are opposite, the two racks can be meshed with the corresponding parallel shaft gears 44 at different positions in the rotation process, and then when the two turning shovel pieces 39 drive the corresponding crops to rotate to different positions and heights, after the cover plates 40 on the corresponding crops are removed, the crops can fall at different positions and heights, so that the effect of turning the crops can be effectively improved, and the uniformity of heated and dried crops is improved.

Waste heat recovery: in the process of heating crops in the first drying cylinder 30 and the second drying cylinder 31, generated hot air flows into the processing box 1 through a plurality of radiating holes, at the moment, an exhaust fan and a servo motor 18 are started, the air in the processing box 1 is sucked into the air conveying pipe 8 through the air suction pipe 9, the air entering the air conveying pipe 8 flows into the air guide pipe and the branch pipe 17 respectively after being matched and filtered by the first filter screen 10 and the second filter screen 11, and the air entering the air guide pipe flows into the two guide pipes 15 along the connecting pipe 14 and is blown out by the plurality of blowing pipes 16 to preheat the crops in the preheating box 3;

the gas entering the branch pipe 17 flows into the plurality of ventilation grooves along the annular cavity, the air inlet pipe 23 and the cavity, and finally is blown out from the plurality of air outlets to perform further preheating treatment on crops, and meanwhile, the servo motor 18 works to drive the plurality of stirring rods 20 to rotate through the rotating shaft 19 to stir the crops, so that the preheating uniformity of the crops can be effectively improved.

And (3) discharging crops: after the heating of the crops is completed, the servo motor 18, the servo driver 25, the exhaust fan and the suction fan 34 are turned off, and then the valves on the discharge pipe 32 are sequentially opened, so that the crops in the first drying cylinder 30 and the second drying cylinder 31 can be collected.

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.
