The solenoid valve 504 is used to adjust the direction, flow rate, speed and other parameters of the medium. The top end of the piston 502 is fixedly connected with a plug 505. Slide grooves 506 are formed on both sides of the plug 505. The inner walls of the two slide grooves 506 are fixedly connected with two second springs 507. One ends of the two second springs 507 far from the inner walls of the slide grooves 506 are fixedly connected with trapezoidal blocks 508. The trapezoidal blocks 508 are adapted to the inner wall of the storage hopper 9. The two trapezoidal blocks 508 are respectively slidably connected to the inner walls of the corresponding two slide grooves 506.

[0027] As Figure 2 shown, in one embodiment, the screening assembly 4 includes a turntable 401. One side of the turntable 401 is rotationally connected with a swing rod 402 through a round shaft. The end of the swing rod 402 far from the turntable 401 is rotationally connected with a reciprocating rod 403. A limiting groove 404 is formed on one side of the drying box 3. The reciprocating rod 403 is slidably connected with the inner wall of the limiting groove 404. Through the limiting groove 404, the reciprocating rod 403 can maintain an axial reciprocating motion when moving.
