A special-shaped groove 604 is provided on the inner wall of the suction hood 509 and the exhaust hood 510 near the sliding block 603, and the sliding block 603 is slidably arranged in the special-shaped groove 604. The special-shaped groove 604 is arranged in a curved shape, so that when the sliding block 603 slides in the special-shaped groove 604, the protective tube 601 starts to rotate during the movement. A mounting tube 605 is rotatably installed on the inner wall of the protective tube 601. The mounting tube A protective net 606 is fixedly installed at the lower end of 605, a scraper frame 607 is fixedly installed below the protective cylinder 601 near the protective net 606, and the scraper frame 607 contacts the surface of the protective net 606, and a slider 608 is fixedly installed on the upper end of the installation cylinder 605. A sliding groove 609 is opened on the inner wall of the suction hood 509 and the exhaust hood 510 near the slider 608. Specifically, when the protective net 606 begins to be blocked, the protective cylinder 601 begins to move, and the sliding block 603 slides in the special-shaped groove 604, so that the protective cylinder 601 begins to rotate.

The slider 608 prevents the installation cylinder 605 from rotating, and the scraper frame 607 installed on the upper end of the protective cylinder 601 scrapes the protective net 606 installed on the upper end of the installation cylinder 605.

[0030] The working principle of the present invention is as follows: when it is necessary to dry and dehumidify the plastic particles, the plastic particles are placed in the placement cylinder 202, the driving motor 401 is started, the rotating rod 402 drives the conveying cylinder 404 and the transmission cylinder 403 to start rotating, so that the screen 405 and the placement net 406 start to move, the rotating rod 402 rotates to make the toggle circle 305 start rotating, the toggle sheet pushes the spring sheet 304 to start to toggle the transmission rod 303 to transfer the spring vibration to the position of the vibration rod 301, so as to avoid the arrangement cylinder 203 being blocked when the plastic particles are transferred to the arrangement cylinder 203 through the placement cylinder 202 for discharge; After the plastic particles are classified and fall on the surface of the screen 405 and the placement net 406, the screen 405 and the placement net 406 start to move, the transmission motor is started, the dragon rod 410 starts to rotate, the suction pump 502 and the heating box 501 are started, the drying strip 504 starts to spray hot air to dry the plastic particles arranged on the surface of the screen 405 and the placement net 406, the air outlet strip 411 starts to discharge air, so that the hot air sprayed by the air outlet strip 411 dries the plastic particles in the conveying trough 408, and the dried gas carries the water vapor evaporated from the surface of the plastic particles and is discharged to the drying box 507 through the suction hood 509 and the exhaust hood 510, so that the drying box 507 filters the water vapor, thereby making the drying of the plastic particles faster; During the process of drying the plastic particles, the protective net 606 set in the suction hood 509 and the exhaust hood 510 filters out debris. When the protective net 606 begins to be blocked, the protective cylinder 601 begins to move, and the sliding block 603 slides in the special-shaped groove 604, causing the protective cylinder 601 to start rotating. When the protective cylinder 601 moves, it drives the installation cylinder 605 to start moving. The slider 608 prevents the installation cylinder 605 from rotating. The scraper frame 607 installed on the upper end of the protective cylinder 601 scrapes the protective net 606 installed on the upper end of the installation cylinder 605, thereby preventing the exhaust ports of the suction hood 509 and the exhaust hood 510 from being blocked by debris and causing the heating temperature to be too high.
