The packing auger is arranged in the first pipe section 51 and is driven by the motor to convey the grains at the discharge port of the drying mechanism 3 to the second end of the first pipe section 51. A lifting hopper is mounted within second tube section 52 and lifts the grain at the second end of first tube section 51 to the second end of second tube section 52. The first end of the flexible pipe 53 is connected to the second end of the second pipe section 52, the flexible pipe 53 in this embodiment is a rubber corrugated pipe, and other flexible pipes 53 such as a metal corrugated pipe can be selected in other design manners, so that the grains reaching the second end of the second pipe section 52 can enter the rubber corrugated pipe. The first material guiding cylinder 54 is connected with the second end of the rubber corrugated pipe, and the height of the second end of the rubber corrugated pipe is lower than that of the first end of the rubber corrugated pipe, so that grains in the corrugated pipe can slide from the first end of the rubber corrugated pipe to the second end of the corrugated pipe under the action of self gravity and then reach the first material guiding cylinder 54. Referring to fig. 2, the first material guiding cylinder 54 in this embodiment is slidably mounted on the top of the grain storage mechanism 1, and the sliding direction of the first material guiding cylinder 54 is parallel to the arrangement direction of the three grain storage cavities 11.

Then dry the 30% maize of moisture content to the moisture content is 26%, first storage grain chamber 11 directly over when removing first guide cylinder 54, start hoist mechanism 5, hot-blast continuous conveyor gets into the stoving intracavity, open the first valve 4 of first storage grain chamber 11 bottom, the maize in first storage grain chamber 11 falls into the stoving intracavity a bit under the action of gravity, obtain drying at the stoving intracavity, under the drive of auger and hopper, the maize that falls into the stoving intracavity is promoted to second pipeline section 52 second end, and get back to again in first storage grain chamber 11 along rubber bellows and first guide cylinder 54, thereby realize the circulation stoving to the maize in first storage grain chamber 11. The hygrometer 2 in the first grain storage cavity 11 monitors the humidity of the corns in real time, and a computer calculates an average humidity value. When the moisture content of the corns in the first grain storage cavity 11 reaches 26%, the first valve 4 at the bottom of the second grain storage cavity 11 is opened, the corns in the second grain storage cavity 11 begin to be dried, at the moment, the first guide cylinder 54 reciprocates above the first grain storage cavity 11 and the second grain storage cavity 11, so that the corns discharged from the first guide cylinder 54 uniformly fall into the first grain storage cavity 11 and the second grain storage cavity 11, and at the moment, the corns in the first grain storage cavity 11 and the second grain storage cavity 11 are dried in a mixed mode. When the moisture content of the corns in the first grain storage cavity 11 and the second grain storage cavity 11 is monitored by the hygrometer 2 to reach 22%, the first valve 4 at the bottom of the third grain storage cavity 11 is opened, the corns in the third grain storage cavity 11 begin to be dried, at the moment, the first guide cylinder 54 reciprocates above the first grain storage cavity 11, the second grain storage cavity 11 and the third grain storage cavity 11, so that the corns discharged by the first guide cylinder 54 uniformly fall into the first grain storage cavity 11, the second grain storage cavity 11 and the third grain storage cavity 11, at the moment, the corns in the first grain storage cavity 11, the second grain storage cavity 11 and the third grain storage cavity 11 are mixed and dried, finally, the moisture content of the corns in the first grain storage cavity 11, the second grain storage cavity 11 and the third grain storage cavity 11 reaches 13% at the same time, the drying is stopped, and the drying is finished.
Another drying method can also be adopted, the first material guiding cylinder 54 is firstly moved to the position right above the first grain storage cavity 11, the corns in the first grain storage cavity 11 are dried until the moisture content of the corns in the first grain storage cavity 11 reaches 22%, and then the first valve 4 at the bottom of the first grain storage cavity 11 is closed. The first material guide cylinder 54 is moved to the position right above the second grain storage cavity 11, and the corns in the second grain storage cavity 11 are dried until the moisture content of the corns in the second grain storage cavity 11 reaches 22%. And opening all the first valves 4 again, driving the first guide cylinder 54 to reciprocate above the first grain storage cavity 11, the second grain storage cavity 11 and the third grain storage cavity 11, mixing and drying the corns in the first grain storage cavity 11, the second grain storage cavity 11 and the third grain storage cavity 11 at the moment, finally, simultaneously reaching 13 percent of moisture content of the corns in the first grain storage cavity 11, the second grain storage cavity 11 and the third grain storage cavity 11, stopping drying at the moment, and finishing drying.
