Pipe 2 15 is rotatably connected to the tunnel kiln body 1, and nozzle 2 16 is provided on pipe 2 15. When the tunnel kiln rapid drying device is used, the rack 10 is driven by the motor 2, thereby driving the first circular gear 11 and the second circular gear 14 to reciprocate, so that nozzle 13 and nozzle 2 16 swing back and forth, thereby achieving uniform distribution of hot air, not only ensuring that all areas of the material surface can be evenly exposed to the hot air, but also accelerating the heat conduction process between the material surface and the hot air, so that the material can absorb heat and evaporate moisture faster, significantly shortening the drying time and improving production efficiency.

Then the staff pushes the kiln car 26 loaded with materials onto the track 27. When the kiln car 26 is pushed into the tunnel kiln body 1, the fixed plate 22 is released, and the rebound effect of the two sets of springs 25 drives the two sets of telescopic rods 24 and the two sets of baffles 23 to slide upward and reset, thereby resetting the rear wheels of the kiln car 26. The blocking not only makes the material on the kiln car 26 more stable, but also enables the subsequent hot air to be blown more evenly to various parts of the material, thereby improving the drying quality.

At the same time, the rotating shaft 5 drives the disc 6 to rotate, and the disc 6 drives the fixed block 7 to rotate through the eccentric connection. The fixed block 7 drives the wedge ring 8 to move back and forth, and the wedge ring 8 drives the slide rod 9 to slide back and forth on the tunnel kiln body 1.
