[0024] Working principle: Before use, the drying cylinder 1 is installed in a suitable position by bolts and a mounting frame; When in use, a proper amount of soil sample is injected into the drying cylinder 1 through the feed hopper 4, and then the heater in the drying cylinder 1 is turned on to dry the soil in the drying cylinder 1; during drying, the drive motor 3 is started, and the output shaft of the drive motor 3 is rotated clockwise, so that the stirring shaft 16 drives the annular plate 17, the connecting frame 14 and the stirring blade 15 to rotate, thereby drying the soil in the drying cylinder 1; When the output shaft of the driving motor 3 rotates clockwise, the circular screen 10 is at the bottom of the stirring shaft 16 and idles, so that the circular screen 10 is located at the bottom of the discharge pipe 5 and does not rise; When the connecting frame 14 rotates, it drives the rotating block 20 to rotate, and the arc surface 30 on the rotating block 20 cooperates with the arc surface 29 on the top block 19 to move the rotating block 20 to the top block 19, thereby realizing the lifting of the stirring blade 15.

When drying is completed, the drive motor 3 is controlled to rotate the output shaft of the drive motor 3 counterclockwise, and then the internal thread on the circular screen 10 is engaged with the external thread 11 on the stirring shaft 16 under the extrusion of the extrusion spring 24, and then the circular screen 10 is moved upward under the cooperation of the rectangular groove 6 and the slider 22; The circular screen 10 moves upward, which drives the push rod 9 to move upward, and then drives the blocking block 18 to move upward, so that the blocking block 18 is moved upward. Then, the discharge pipe 5 is opened, and the dried soil in the drying cylinder 1 flows along the discharge pipe 5 onto the circular screen 10; As the circular screen 10 moves upward, the slider 22 is driven to move upward. When the slider 22 moves to the annular groove 7, the arc surface 1 27 and the arc surface 4 32 on the limit block 26 are opposite to each other, so that the slider 22 moves into the annular groove 7, and the fixation of the circular screen 10 is released, so that the circular screen 10 rotates with the stirring shaft 16, thereby achieving soil screening. When the screening is completed, the drive motor 3 is controlled to make the output shaft of the drive motor 3 rotate clockwise, and then under the action of the extrusion spring three 25, the limit block 26 is clamped in the rectangular groove 6, so as to limit the circular screen 10, and then the circular screen 10 moves downward, and the circular screen 10 will drive the blocking block 18 to move upward when moving downward. Finally, after the circular screen 10 is reset, the blocking block 18 blocks the discharge pipe 5 for reuse.
