The invention relates to a drying device, in particular to an agricultural rapeseed drying device. The technical problem to be solved is to provide an agricultural rapeseed drying device which is short in drying time, is not affected by the weather and does not need manual stirring. According to the technical scheme, the agricultural rapeseed drying device comprises first supports, a heating cylinder, a heating device, a second support, a fixing rod, a first motor, a blade, an air-out scoop, an air suction pipe, an installation a seat, an air pump, a first blowing pipe and the like, wherein the heating cylinder is arranged on the first supports of the left and right sides; the heating device is arranged in the heating cylinder; the second support is arranged on the right side of the heating cylinder; the fixing rod is fixed in the second support; and the first motor is arranged on the fixing rod and is located on the right of the heating device. The arranged heating device can heat air, so that the agricultural rapeseed drying device can quickly dry rapeseeds, and shortens the drying time of the rapeseeds. The agricultural rapeseed drying device is not affected by the weather, anddoes not cause the loss of people due to the weather.
