Description

Technical Field

[0001] The utility model relates to the technical field of grain production and drying, in particular to a drying device for grain production. Background Art

[0002] Grain processing refers to the business activities of converting raw grain into semi-finished grain or finished grain, or converting semi-finished grain into finished grain. When grain is processed, it is necessary to dry the grain. Drying can increase the storage time of grain and effectively prevent grain from being damaged by insects.

[0003] After searching, Chinese patent application No. 202120120444.4 discloses a drying device for grain production, including a box body, a horizontal discharge barrel is arranged on the inner side of the box body, and a discharge port is arranged at the right end of the discharge barrel through the right side wall of the box body, a continuously rotating discharge screw rod is arranged on the inner side of the discharge barrel, and evenly arranged air inlet holes are arranged on the outer surface of the discharge barrel, and hot air mechanisms are arranged on the front and back sides of the box body to blow hot air to the inside of the box body, and the grain is poured into the feeding hopper, and then the feeding hopper is opened to discharge the grain into the discharge barrel. At this time, the grain is evenly transported to the discharge port through the continuously rotating discharge screw rod, and hot air is continuously blown into the box body through the hot air mechanism. The hot air is blown into the discharge barrel through the air inlet holes on the discharge barrel to heat and dry the grain evenly and quickly, and the dried grain is discharged under the drive of the discharge screw rod, so that the drying efficiency of the grain is higher and the drying effect is better.

[0004] Although the above patent transports the grain to the discharge port evenly through the continuously rotating discharge screw rod, and blows hot air into the discharge barrel through the air inlet holes on the discharge barrel to heat and dry the grain evenly and quickly, the dried grain is discharged under the drive of the discharge screw rod, which makes the grain drying efficiency higher and the drying effect better. However, in actual use, the patent lacks a ejection structure for the air inlet holes, which makes it easy for the grain to get stuck in the air inlet holes during the transmission process, making it impossible for some air inlet holes to pass hot air, and it is also more troublesome to clean them later, thereby reducing the drying effect to a certain extent.

[0005] Therefore, it is necessary to modify the drying device in the above patent to effectively prevent the grain from being easily stuck in the air inlet during the transmission process, making some air inlets unable to pass hot air, thereby reducing the drying effect to a certain extent.
