The top end of the rotating shaft passes through the drying chamber and is rotatably mounted to the top of the drying chamber. Several support plates are evenly distributed on the inner surface of the drying chamber. The support plates are rotatably mounted to the rotating shaft via bearings. At least two drying boxes are evenly distributed on the upper surface of the support plates. A limiting component is provided between the drying boxes and the rotating shaft to fix the drying boxes and the rotating shaft during the drying process, so that the rotating shaft is driven by the motor to rotate, ensuring uniform heating of the drying boxes and uniform drying of the soil sample.

[0008] Preferably, the limiting component includes a hinged base, a limiting card one, and a limiting card two. The hinged base is provided on the surface of the rotating shaft above the drying box. The limiting card one is provided on the top surface of the drying box. The limiting card two is provided on the surface of the rotating shaft above the hinged base. A locking plate one is rotatably installed on the hinged base. When placing a soil sample, the locking plate one rotates upward and engages with the limiting card two.

Three drying boxes are evenly arranged on the support plates. The support plates are connected to the rotating shaft through bearings. When a soil sample is placed, the support plates are rotated to facilitate the placement of multiple soil samples, so that multiple soil samples can be placed on each layer of support plates, thereby improving the drying efficiency of soil samples and quantifying the drying process.

[0013] After the soil samples are placed on each support plate, the drying box and the rotating shaft are fixed and installed by the limiting component during the drying process. The rotating shaft is driven by the motor to rotate, so that the drying box is heated evenly and the soil samples are dried evenly.

[0014] The surface of the rotating shaft above the hinge base is provided with a second limiting card. The hinge base is rotatably mounted with a first card.
