The invention discloses an airing device for automatically turning over corn. The device comprises a base, support rods are fixedly connected to both sides of the top of the base, a vibration box penetrates the top of the surface of each support rod, both the top and the bottom of the inner cavity of the vibration box are fixedly connected to springs, and one end, far away from the vibration box,of each spring is fixedly connected to a fixing plate. According to the invention, through the arrangement of the supporting rods, the vibration box, the springs, the fixing plate, a connecting rod, afilter plate and a vibration motor, the effect of jointly constructing the airing device for automatically turning over corn is achieved, the supporting rods can increase the stability of the vibration box, and the springs and the fixing plate can support the buffering force of the connecting rod, so that the filter plate does not shake during vibration; and through the arrangement of the filterplate and the vibration motor, the vibration motor vibrates to realize the vibration of the filter plate so as to realize the automatic turn-over of corn, so that the problems of troublesome operationand low efficiency of the existing corn airing mode are solved.
