An exhaust pipe 9 is fixedly communicated with one side of the shunt pipe 6 close to the drying box 1. The number of the exhaust pipes 9 is several. The several exhaust pipes 9 are evenly distributed on the surface of the shunt pipe 6, and the several exhaust pipes 9 all penetrate through the outer wall of the drying box 1 and extend into the drying box 1. A plurality of air jet ports 8 are fixedly communicated with the lower side of the exhaust pipe 9. The plurality of air jet ports 8 are evenly distributed at the bottom of the several exhaust pipes 9, and the plurality of air jet ports 8 are located above the bearing tray 12.

[0026] Working principle: When in use, the staff opens the box door 2 by holding the door handle 4, and evenly spreads the soil to be dried on the three bearing trays 12.
