At this time, external air enters the fixed cover 902 through the air inlet pipe 905. When the sliding block 903 moves upward, the air in the fixed cover 902 can be squeezed. At the same time, the first one-way valve 907 is closed and the second one-way valve 908 is opened. At this time, the air in the fixed cover 902 is squeezed and enters the movable pipe 601 through the air supply pipe 906 and the third hose 604, and is blown on the outer surfaces of the first filter cartridge 16 and the second filter cartridge 17 through the air blowing pipe 602, which can form a backblowing effect on them, thereby improving the efficiency and effect of cleaning the first filter cartridge 16 and the second filter cartridge 17, and thereby improving the efficiency and effect of its screening.

When the semicircular block 1002 abuts against the bottom of the sliding block 903, the sliding block 903 is pushed to move upward along the fixed cover 902.

Working principle: When in use, during screening, the first motor 13 is started, and the rotation of the first motor 13 drives the rotation of the rotating shaft 12 and the rotating ring 14, thereby driving the rotating drum 15 to tilt, thereby adjusting the tilt angles of the rotating drum 15, the first filter drum 16 and the second filter drum 17;

Next, the second motor 202 is started. The rotation of the second motor 202 drives the rotation of the rotating rod 203 and the gear 204, and then drives the rotation of the ring gear 201 and the rotating drum 15. At the same time, the control valve at the bottom of the storage box 21 is opened, so that the material inside enters the first filter drum 16 through the first hose 22. When the rotating drum 15 rotates, it drives the first filter drum 16 and the second filter drum 17 to rotate synchronously, so that the material is screened through the first filter hole 18 and the second filter hole 19 in turn. The screened impurities slide downward along the first filter drum 16 and the second filter drum 17 and enter the collection box 25 through the second hose 26 and the discharge pipe 24 for collection. The screened powder slides downward along the rotating drum 15 and enters another collection box 25 through the second hose 26 and the discharge pipe 24 for collection. In addition, during screening, the rotation of the rotating drum 15, the first filter drum 16 and the second filter drum 17 can avoid material accumulation and improve screening efficiency and effect.

When the rotating drum 15 rotates, when the first rubber rod 503 abuts against the side wall of the first tapered rod 502, the movable plate 301 and the knocking pin 302 can be pushed to move downward. At the same time, the first spring 402 is compressed. When the first rubber rod 503 passes over the first tapered rod 502, the movable plate 301 and the knocking pin 302 can move upward and reset under the action of the first spring 402. In this way, the knocking pin 302 can reciprocately knock and vibrate the side wall of the rotating drum 15, and transmit the vibration to the first filter drum 16 and the second filter drum 17, which can not only avoid the blockage of the first filter drum 16 and the second filter drum 17, but also facilitate the downward sliding of impurities and powder for collection, thereby improving the efficiency and effect of screening.

At the same time, when the rotating cylinder 15 rotates, the second tapered rod 802 is driven to rotate synchronously. When the second rubber rod 801 abuts against the side wall of the second tapered rod 802, the movable tube 601 and the bristles 603 can be pushed to move, and the sliding plate 701 and the movable tube 601 can be driven to move. At the same time, the second spring 703 is compressed. When the second rubber rod 801 passes over the second tapered rod 802, the movable tube 601 and the bristles 603 can be moved and reset under the action of the second spring 703. In this way, the bristles 603 can clean the outer side walls of the first filter cylinder 16 and the second filter cylinder 17 to avoid clogging and ensure the efficiency and effect of filtering.

Furthermore, when the rotating rod 203 rotates, the fixed ring 1001 is driven to rotate synchronously. When the semicircular block 1002 abuts against the bottom of the sliding block 903, the sliding block 903 is pushed to move upward along the fixed cover 902. At the same time, the third spring 904 is compressed. When the semicircular block 1002 passes over the sliding block 903, the sliding block 903 can move downward and reset under the action of the third spring 904. This reciprocating process can make the sliding block 903 move back and forth in the fixed cover 902. When the sliding block 903 moves downward, negative pressure is generated in the fixed cover 902. At the same time, the first one-way valve 907 is opened, and the second one-way valve 908 is closed. Closed. At this time, external air enters the fixed cover 902 through the air inlet pipe 905. When the sliding block 903 moves upward, the air in the fixed cover 902 can be squeezed. At the same time, the first one-way valve 907 is closed and the second one-way valve 908 is opened. At this time, the air in the fixed cover 902 is squeezed and enters the movable pipe 601 through the air supply pipe 906 and the third hose 604, and is blown on the outer surfaces of the first filter cartridge 16 and the second filter cartridge 17 through the air blowing pipe 602, which can form a backblowing effect on them, thereby improving the efficiency and effect of cleaning the first filter cartridge 16 and the second filter cartridge 17, and thereby improving the efficiency and effect of screening.
