The invention relates to the technical field of drying devices, in particular to a wind power drying device for airing agricultural products. The wind power drying device for airing agricultural products comprises a device body, the device body comprises a drying cavity, the right end of the drying cavity is in bearing connection with a first side plate, the left end of the first side plate is fixedly connected with an output shaft, the outer wall of the output shaft is sleeved with a second side plate, and the left end of the second side plate is fixedly connected with a motor. By means of the wind power drying device, the problems that when an existing wind power drying device is used, crops are generally smashed and then placed in a leakage net, sunlight irradiation is more uniform by rotating the leakage net, but a large quantity of impurities exist in the crops when the crops are stirred, the traditional drying device does not have the dust removal function, consequently, an operator needs to remove the impurities after the crops are dried in the sun, time and labor are wasted, a large amount of labor time is consumed, and the labor amount of the operator is increased are solved, dust removal of agricultural products is more convenient, the workload of the operator is reduced, and the device is more convenient to use.
