[0044] Among them, the air outlet cleaning mechanism includes a rotating frame 801, a connecting column 802 and a debris scraper 803. The rotating frame 801 is fixedly sleeved on the outer wall of the transmission main shaft 603, the connecting column 802 is fixedly inserted into the surface of the rotating frame 801, and the debris scraper 803 is fixedly sleeved on the surface of the rotating frame 801, and the surface of the debris scraper 803 is slidingly connected to the surface of the annular dust screen 702. The rotating frame 801, the connecting column 802 and the debris scraper 803 are arranged so that the rotating frame 801 can drive the debris scraper 803 to rotate, and the debris attached to the surface of the annular dust screen 702 is scraped off by the debris scraper 803 to prevent the annular dust screen 702 from being blocked by debris.

[0045] Working principle: when in use, the device is placed horizontally so that the air guide tube 101 faces upward, and the drive motor 602 is started. The drive motor 602 drives the transmission main shaft 603 to rotate forward and reverse periodically. When the transmission main shaft 603 rotates, it drives the centrifugal blades 604, the driving gear 605 and the rotating frame 801 to rotate back and forth. When the centrifugal blades 604 rotate back and forth, they can generate negative pressure to continuously pressurize and transport the external air to the inside of the rotating screening bowl 501. When transporting airflow, the air first passes through the isolation mesh 304 and enters the interior of the protective shell 301. Then it passes through the annular dust screen 702 and the annular dust screen sponge 705 and enters between the air inlet plate 701 of the air housing and the supporting sealing plate 703. At this time, the impurities in the air are blocked outside by the annular dust screen sponge 705 and the annular dust screen 702. Then the air flow enters the air guide housing 601 from the air inlet 704 of the air housing. The air flow entering the air guide housing 601 is centrifugally thrown by the centrifugal blades 604 and accelerated to the surroundings. Then the air flow is accelerated to enter the annular cylinder air gap 102 from the air housing air outlet 606 and the air gap air inlet 104, and then along the annular cylinder air gap 10 2 moves downward. At the same time, the rotating frame 801 rotates forward and drives the scraper blade 803 to rotate. The rotating scraper blade 803 scrapes off the debris attached to the surface of the annular dust screen 702 to prevent the debris from clogging the annular dust screen 702. At the same time, the driving gear 605 drives the driven gear 402 to rotate back and forth, causing the connecting cylinder 401 to rotate back and forth. The connecting cylinder 401 drives the rotary screening bowl 501 to rotate back and forth, and then the rock particles are put into the rotary screening bowl 501 through the material port 103. The rock particles are screened by the rotating rotary screen. The bowl 501 drives the rock cuttings to rotate back and forth, and a centrifugal effect is generated when the rock cuttings particles rotate, causing the larger rock cuttings particles to move outward away from the rotation center, and the smaller rock cuttings particles to move inward close to the rotation center. The smaller rock cuttings particles moving inward fall through the sieve holes at the bottom of the rotating screening bowl 501. At the same time, the high-speed airflow moving downward from the annular wind gap 102 blows the lighter particles and waste chips on the surface of the rock cuttings particles out of the material port 103, so that the larger rock cuttings particles remain inside the rotating screening bowl 501, thereby realizing the screening of rock cuttings particles.

[0046] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
