This cereal shines and receives all-in-one has two kinds of working methods, and one kind working method is the mode of sunning cereal, and the second kind working method is the mode of retrieving the packing cereal, specifically as follows:

(1) airing grains

Firstly, the storage bin 2 is filled with grains to be aired, and then the traveling motor is started to drive the wheels 6 so as to enable the frame 1 to travel forwards. When the frame 1 moves forwards, the grain discharging motor 8 is started, and the grain discharging motor 8 rotates forwards. The grain outlet motor 8 rotates forwards and then drives the spiral feeding blade 10 to rotate forwards synchronously through the rotating shaft 9, grains to be aired in the bin 2 move downwards under the action of gravity and are pushed forwards by the spiral feeding blade 10 rotating forwards after moving downwards, and finally the grains to be aired vertically fall to the ground through the airing outlet 11. As the carriage 1 continues to move forward, the grains falling to the ground are flattened by the scraper 13 and spread for airing. At this point, a working cycle of airing grains is finished, during which time grains to be aired can be replenished into the silo 1.

(2) Recovering packaged grain

The grains need to be packed, transferred and stored after the airing is finished. At this time, the running motor is started to drive the wheels 6 to cause the frame 1 to run forward. When the frame 1 moves forwards, the transmission motor and the grain discharging motor 8 are started, and the grain discharging motor 8 is enabled to rotate reversely. The bucket 15, which travels forward with the carriage 1, collects grains aired on the ground backward into the grain collection box 14. The transmission motor is started, the rolling sweeper 16 and the conveyor belt 18 run together, and the rolling sweeper 16 runs to convey grains collected in the grain collecting box body 14 back continuously through the notch 21. The grains conveyed backwards through the notches 21 are caught by the material pockets 19 one by one and are lifted upwards under the drive of the conveyor belt 18, and the grains caught by the material pockets 19 are finally lifted into the silo 1. Since the material bag 19 is provided with a dust outlet, the rising of the material bag 19 and the vibration of the frame 1 can screen out the dust in the grains, and the screened dust can fall to the bottom of the conveying box 17 and be discharged by the dust outlet.

The conveying grain discharging motor 8 drives the spiral feeding blades 10 to synchronously rotate reversely through the rotating shaft 9 after rotating reversely, grains which are aired in the storage bin 2 move downwards under the action of gravity and are pushed backwards by the reverse spiral feeding blades 10 after moving downwards, and finally, the grains which are aired completely fall into the guide chute 22 through the packing outlet 12 and are output backwards to the rear side of the frame 1 along the guide chute 22. The packing of the grains can be finished by sleeving a special packing bag at the rear side of the material guide groove 22. At this point, a recycling bale cycle is completed, during which time the bags are continuously applied until all the bales are completed.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
