When the driving gear is meshed with the rack, the driving gear drives the rack to move, then the sliding block slides towards the center of the sliding cavity, when the rack moves, the driven gear is pushed to rotate, the driving air guide plate rotates synchronously along with the driven gear, and when the driving air guide plate rotates, the driven air guide plate is driven to rotate synchronously through the belt wheel and the transmission belt. The reciprocating mechanism drives the driving air deflectors on the front side and the rear side to rotate in the opposite directions, hot air flows to the front side and the rear side of the curing barn through the driving air deflectors and the driven air deflectors, the blowing range of the air inlet pipeline is further enlarged, tobacco leaves in different ranges are evenly heated, and the curing characteristic difference is reduced.
