[0050] The working principle of the present invention is:

[0051] When in use, after the two reamers 11 have crushed the plastic, the plastic particles fall into the inside of the mixing barrel 101, and the spiral plate 107 is driven to rotate as the central rod 106 rotates, so that the plastic particles falling into the mixing barrel 101 are fully cleaned, and then the plastic particles in the mixing barrel 101 are squeezed to the right side of the isolation plate 102 as the spiral plate 107 rotates. The commonly used polymer plastics are usually made of polyethylene (PE) and polypropylene (PP). The density of these plastic particles is smaller than that of water, so they float on the water surface, and as the plastic particles accumulate more and more, they are dumped on the top of the sorting plate 104, and then the driving rod 207 rotates to drive the active gear to rotate, and then the toothed belt 211 drives the passive gear 206 to rotate. At this time, when the passive gear 206 rotates, the eccentric block 210 is driven to rotate through the passive rod 208, so that the stirring plate 203 moves up and down. During the up and down movement of the stirring plate 203, the plastic particles accumulated on the top of the sorting plate 104 are evenly spread on the top of the sorting plate 104;

[0052] At the same time, when the center rod 106 rotates, the crests and troughs of the corrugated groove 113 alternately push the abutment protrusion 112, so that the movable cylinder 108 reciprocates left and right, and the blown gas comes to the inside of the conductive tube 309 through the gas supply pipe 303, and then pushes the sealing block 314 to move to the left side under the action of pressure, so that the air can come to the chamber on the left side of the movable plug 307 through the output groove 312, and as the air in the chamber on the left side of the movable plug 307 increases, the movable plug 307 moves away from the conductive tube 309, and the storage spring 308 is compressed. Then, when the movable plug 307 moves to the right side of the storage tube 304, the traction line 310 is stretched straight and pulls the conductive tube 306 to move to the right side, and the air holes on the outer surface of the conductive tube 306 are The movable plug 307 is exposed inside the power storage tube 304, and at the same time, the conductive tube 309 moves to the left. Then, when the conductive tube 309 moves to the left, the air holes on the outer surface of the conductive cover 311 are exposed, and the gas input from the gas delivery tube 303 directly flows out from the air holes on the outer surface of the conductive cover 311, and then flows out from the air discharge groove 315. At this time, there is no continuous pressure provided by the left chamber of the movable plug 307, so that the elastic force of the power storage spring 308 begins to release, pushing the movable plug 307 to move toward the direction of the conductive tube 306. Since the sealing block 314 blocks the air inlet of the water delivery tube 302, the movable plug 307 can push the gas through the conductive tube 306 and the gas guide tube 305 to enter the interior of the telescopic tube 202 when moving, thereby causing the movable box 301 to move upward;

[0053] Subsequently, the water spray pipe 403 is pushed to move to the left side by the elastic force of the passive spring 408, so that the passive block 402 is exposed outside the movable box 301, and the water pump 105 pumps the water flow to the inside of the connecting pipe 404 through the water delivery pipe 302, and then sprays it out through the water spray pipe 403 to flush the plastic particles above the sorting plate 104, flushing the fine particles of plastic down and falling into the sieve holes on the outer surface of the sorting plate 104 with the water flow, and finally the plastic particles of qualified size are transported to the outside of the sorting box 1 along the conveyor belt 4;

[0054] When the force storage spring 308 completely releases its elastic force, the conductive tube 309 and the conducting tube 306 squeeze each other, and the conductive tube 309 returns to its initial state, while the conducting tube 306 moves to the left. Then the movable box 301 slowly moves downward under the action of gravity, and the gas inside the telescopic tube 202 flows out from the through hole on the outer surface of the conducting tube 306.

[0055] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed in the present invention, which should be covered by the protection scope of the present invention.
