[0002] Grain drying is to reduce the moisture content of grains, prevent mildew, maintain the freshness and edible quality of grains, and at the same time maintain the germination rate of grains, which is of great significance for ensuring food security, improving agricultural production efficiency and the quality of agricultural products. Grain dryers use hot air to evaporate and remove the moisture in the grains, so as to achieve the purpose of drying and reducing the water content of the grains. When the grain dryer works, the air heated by the hot blast stove is sent into the hot air chamber of the drying section under the action of the fan. The hot air passes horizontally through the grain layer in the drying section, makes full contact with the grains, heats, warms up and reduces the water content of the grains, and the exhausted gas after drying is discharged into the atmosphere to form a circulating drying process.

[0041] The working principle of the present utility model is as follows: When drying grains, first move the drying device to the drying location, and then rotate the baffle shaft 12 to block the baffle plate so that the baffle plate is located at the opening of the discharge pipe 11, and use the baffle plate to close the discharge pipe 11 to prevent grains from being discharged from the discharge pipe 11 of the elevator 9. Then, convey the grains from the feed shell of the elevator 9 into the elevator 9. The elevator 9 conveys the grains upward and through the feed pipe 10 into the feed hood 14.

[0042] The centrifugal fan continuously conveys the hot air generated by the combustion furnace 4 to the inner cage body 32 through the hot air inlet pipe 5 and the hot air outlet pipe 6. The infrared heating tube 34 heats the hot air entering the inner cage body 32 to further increase the temperature of the hot air.

The hot air dries the grains that are falling downward in the outer cage body 16. The moisture generated by drying the grains is discharged to the outside of the outer cage body 16 through the mesh holes of the outer cage body 16 itself. The dried grains fall into the discharge cover 17 and are collected by the discharge cover 17, and then are discharged through the discharge cylinder 20. While the grains are being discharged through the discharge cylinder 20, the output shaft of the feeding motor 22 drives the feeding shaft 23 to rotate, the feeding shaft 23 drives the feeding blades 24 to rotate, and the feeding blades 24 stir the grains at the discharge cylinder 20 to enable the grains to be smoothly discharged from the discharge cylinder 20. Then the grains fall onto the conveyor 7. After being conveyed by the conveyor 7, the grains enter the elevator 9 again through the feeding housing on the elevator 9, and are conveyed upward by the elevator 9 and then conveyed to the feeding cover 14 through the feeding pipe 10 for drying operation again.

[0043] When the grains are dried, the baffle shaft 28 rotates to block the plate again. The blocking plate rotates to the opening position of the feeding pipe 11 to close the feeding pipe 11. Then the elevator 9 conveys the grains to the position of the discharge pipe 11, and the grains are discharged through the discharge pipe 11 to complete the drying operation.
