[0068] An L-shaped baffle 209 is provided at the end of the support rod 205 close to the short pillar 207. When the drying surface 70 is opened, a raised blocking surface is formed on the drying surface 70 to prevent the grain from falling into the recovery bucket 401 of the recovery bagging mechanism 40; when the drying surface 70 is folded, the raised blocking surface disappears due to the rising of the nylon drying surface 70, thereby allowing the grain to fall smoothly into the recovery bucket 401.

The notch 701 of the drying surface 70 is a fan-shaped with a central angle of 60°. The drying surface 70 is fixed on fifteen support rods 205. There are two baffles 702, which are respectively arranged on both sides of the notch 701 of the drying surface 70 to prevent grain from falling from the notch 701 when drying grain.

[0076] During operation, the external conveyor belt first transports the grain to the drying surface 70, and the motor 2 301 rotates through the bevel gear reducer 303 to drive the four-rod shaft 304 to rotate, so that the three turning and drying transmission boxes 106 rotate in a circle in the notch of the guide disc 107, and the grain is evenly spread on the nylon net drying surface 70, and the grain is turned over and dried so that the grain can be evenly dried. The reflection surface 601 reflects sunlight to the bottom of the nylon net drying surface 70, accelerating the drying speed of the grain.

[0077] When the drying grain reaches a suitable humidity, the humidity sensor responds and sends a signal which is processed and controlled by the control system to activate the support mechanism 20, so that the hydraulic rod 203 extends. As the hydraulic rod 203 extends, the slider 204 slides upward, pushing the inclined support 202 and the support rod 205 to retract inward, so that the nylon net drying surface 70 is retracted inward, and the dried grain is quickly collected into the recovery barrel 401.

[0078] The grain in the recycling barrel 401 is bagged with the cooperation of the solenoid valve 402 and the weighing scale 502. When the grain reaches the preset weight, the solenoid valve 402 will automatically close according to the feedback of the weighing scale 502, and control the flow rate of the released grain in the recycling barrel 401, thereby achieving standard bagging;

[0079] The guide wheel 505 drives the weighing device to be automatically pushed out along the guide groove, thereby reducing the manpower for carrying.

[0080] The cycle is repeated until all the dried grains are bagged, so that all the dried grains are put back into the bags in a quantitative manner.
