The sliding connection of the sleeve seat on the limiting hole ensures the requirement of horizontal adjustment of Motor 2 132 along with the arc-shaped screen member 131, thereby ensuring the secondary screening of the material by the arc-shaped screen member 131.

[0031] The working principle of the present invention is as follows: when the material is subjected to graded screening, the motor 111 in the driving mechanism 11 is started by the external controller body, and the operation of the motor 111 drives the shaft 81 in the driving shaft 8 to rotate through the linkage assembly 112. The shaft 81 causes the spiral blade 82 integrally provided thereon to move during the rotation process, and the shaft 81 also synchronously drives the movable plate 91 in the transmission member 9 to move during the rotation activity. When the movable plate 91 rotates, it drives the multiple fixed rods 92 and the cross plate 93 to rotate. At this time, the rotation of the multiple fixed rods 92 causes the conical screen drum member 5 to rotate, and the rotation of the cross plate 93 causes the convex rod connected thereto to move. When the convex rod rotates, it slides along the arc-shaped closed groove 1 on the arc plate 102 in the discharging assembly 10, thereby realizing that the movable plate 91 synchronously performs horizontal reciprocating movement under the condition of rotation, driving the conical screen drum member 5 to move synchronously; When the conical screen drum 5 moves laterally, it simultaneously drives the secondary screening mechanism 13 connected thereto to perform synchronous lateral adjustment; After the material to be processed enters the feed hopper, the shaft 81 drives the spiral blade 82 to rotate, continuously conveying the material in the feed hopper to the interior of the conical screen drum member 5. As the conical screen drum member 5 rotates and moves laterally, the material entering the conical screen drum member 5 is quickly screened and processed, so that small materials fall into the arc-shaped screen member 131 in the secondary screening mechanism 13, and large materials are discharged from the right side of the conical screen drum member 5 into the discharge assembly 10, and finally discharged from the bottom end of the discharge cover 101, thereby achieving preliminary screening of the material; The small materials that enter the curved screen member 131 are screened again when the curved screen member 131 is shaken horizontally, so that the small materials are discharged from the bottom of the collecting hopper. After the equipment has been running for a period of time, the material supply to the feed hopper is stopped, and the collection container under the collecting hopper is replaced. Then, the external controller body starts the motor 2 132 in the secondary screening mechanism 13 to rotate half a circle, so that the arc-shaped screen member 131 is flipped. After the arc-shaped screen member 131 is flipped, the screened material inside it falls into the new collection container, thereby achieving efficient screening of the material. During the operation of the device, the external controller body also starts the external dust removal system and the micro air pump body 122 in the self-cleaning mechanism 12. The dust removal system absorbs and cleans impurities such as floating dust inside the device housing 1. During the gas flow, the movement of the micro air pump body 122 causes part of the gas in the dust removal end pipe 121 to pass through the auxiliary pipe on the dust removal end pipe 121 in the self-cleaning mechanism 12, and then enter the blowing box 123 through the air guide pipe 124. Finally, the gas is discharged from the blowing box 123, and the discharged gas enters the interior of the device housing 1 again, and blows and cleans the conical screen drum member 5 to prevent the holes on the conical screen drum member 5 from being blocked. The lateral reciprocating motion of the conical screen drum member 5 causes the left support assembly 6 and the right support plate 7 to adjust synchronously. When the left support assembly 6 moves to the left, the contact rod 623 in the lifting member 62 contacts the inclined surface of the wedge block 63, thereby causing the base block to drive the guide rod 621 to move upward, compressing the reset spring. When the base block moves upward, the telescopic rod is driven upward through the support rod 622. When the telescopic rod moves upward, the L-shaped sleeve 128 in the self-cleaning mechanism 12 moves upward. When the L-shaped sleeve 128 moves, it synchronously drives the guide block to move in the arc-shaped closed groove 2, so that the rotating shaft 126 drives the scraping impeller 127 to rotate, and the rotation of the scraping impeller 127 realizes the scraping and cleaning of the filter screen in the auxiliary pipe, ensuring the diversion flow of the diverted gas, and thus ensuring the cleaning effect of the holes on the conical screen drum member 5.
