The connecting rod 424 drives the arc door panel 411 to move relative to the box body 31 through the extension arm 423 and the locking block 422. The arc door panel 411 rotates relative to the box body 31 under the limiting action of the slide groove 412 and the slider 413, so that the arc door panel 411 is separated from the warehouse opening 35; at this time, the warehouse opening 35 opens upward, which is convenient for adding materials into the box body 31; at this time, the spring 414 is stretched; after the material is filled, the rotating frame 2 drives the box body 31 to rotate in the opposite direction to drive the box body 31 to reset, and the spring 414 resets and pushes the arc door panel 411 to prevent the arc door panel 411 from rotating with it until The arc door panel 411 contacts the stopper rod 421, and the arc door panel 411 covers the port 35 at this time; the push rod 425 drives the card plate 426 to reset, and the locking block 422 drives the extension arm 423 to reset under the action of the reset force of the torsion spring on its hinge shaft, and the locking block 422 is buckled onto the stopper rod 421, thereby preventing the arc door panel 411 from opening during the rotation of the box body 31; then the rotating frame 2 drives the box body 31 to rotate; part of the material in the box body 31 is separated during the rotation process through the arc slot plate 33, and the material in the box body 31 is increased through the ventilation slot 34 The contact area with the air increases the air drying speed; after the air drying is completed, the push rod 425 on the lower side pushes the card plate 426 to move, and the card plate 426 presses down the connecting rod 424, and the connecting rod 424 drives the locking block 422 to disengage from the blocking rod 421 through the extension arm 423. After the arc door panel 411 is unlocked, the box body 31 continues to rotate until the card plate 426 drives the arc door panel 411 to disengage from the warehouse opening 35 through the connecting rod 424 and the extension arm 423. At this time, the warehouse opening 35 is downward, and the material in the box body 31 falls from the warehouse opening 35 into the discharge box 5 under the action of gravity.
