[0022] Please refer to Figure 2In the embodiment, the lower end of the crushing box 1 is provided with a connecting pipe 101 fixedly connected with the sorting box 2, two groups of rotating columns 102 are longitudinally arranged in the crushing box 1, smaller plastic particles enter the sorting box 2 through the connecting pipe 101, a plurality of crushing pieces 103 are transversely arranged around the rotating columns 102, and a rotating motor 104 is arranged at one end of the rotating column 102. When the assembly is completed, the waste plastics are put into the crushing box 1, and the rotating motor 104 is driven to drive the rotating column 102 to rotate the crushing pieces 103, so that the larger waste plastics are crushed into smaller particles.

[0023] Please refer to Figures 3-4 In the embodiment, the strip-shaped clamping blocks 207 drive the large-hole screening plate 202, the medium-hole screening plate 203 and the small-hole screening plate 204 to be positioned and clamped with the rectangular frame 205 along the strip-shaped clamping grooves 208. According to different types or different requirements of waste plastic treatment, the large-hole screening plate 202, the medium-hole screening plate 203 and the small-hole screening plate 204 with appropriate hole diameters are selected, and then the strip-shaped clamping blocks 207 drive the large-hole screening plate 202, the medium-hole screening plate 203 and the small-hole screening plate 204 to be positioned and clamped with the rectangular frame 205 along the strip-shaped clamping grooves 208. The handle 206 is fixedly arranged at one end of the rectangular frame 205. The large-hole screening plate 202, the medium-hole screening plate 203 and the small-hole screening plate 204 are driven by the rectangular frame 205 to be movably clamped with the sorting box 2 along the U-shaped sliding groove 201. The discharge pipe 209 is arranged at the lower end of the sorting box 2. The tiny dust and the like fall out through the discharge pipe 209. The color sorting box 210 is arranged below the discharge pipe 209. When the sorting is completed, the color sorting box 210 is pushed to be directly below the discharge pipe 209. Then the handle 206 is pulled from bottom to top in sequence, and the large-hole screening plate 202, the medium-hole screening plate 203 and the small-hole screening plate 204 are pulled out, so that the plastic particles of different sizes enter the color sorting box 210 for color sorting.

[0024] In the working process, according to different types or different requirements of waste plastic treatment, the large-hole screening plate 202, the medium-hole screening plate 203 and the small-hole screening plate 204 with appropriate hole diameters are selected, and then the strip-shaped clamping blocks 207 drive the large-hole screening plate 202, the medium-hole screening plate 203 and the small-hole screening plate 204 to be positioned and clamped with the rectangular frame 205 along the strip-shaped clamping grooves 208. Then the handle 206 is lifted, and the large-hole screening plate 202, the medium-hole screening plate 203 and the small-hole screening plate 204 are driven by the rectangular frame 205 to be movably clamped with the sorting box 2 along the U-shaped sliding groove 201.

[0025] When all the assembly is complete, the waste plastics are put into the crushing box 1, and at the same time, the driving of the rotating motor 104 makes the rotating column 102 drive the crushing pieces 103 to rotate, so as to crush the larger waste plastics into smaller particles. Then the smaller plastic particles enter the sorting box 2 through the connecting pipe 101, and are sorted out by the large-hole screening plate 202, then the medium-sized particles are sorted out by the medium-hole screening plate 203, and then the smaller particles are sorted out by the small-hole screening plate 204, and then the tiny dust and the like fall out through the discharge pipe 209.

[0026] When all the sorting is completed, the color selection box 210 is pushed to be directly below the discharge pipe 209, and then the handle 206 is pulled from bottom to top in turn, and the large-hole screening plate 202, the medium-hole screening plate 203 and the small-hole screening plate 204 are pulled out, so that the plastic particles of different sizes enter the color selection box 210 for color sorting.

[0027] Through the above steps, according to different types or different requirements of waste plastic treatment needs, the appropriate aperture screening plate is selected, which is assembled with the sorting box 2, then the waste plastics are put into the crushing box 1 to be crushed into smaller particles, and then the size screening is carried out in the sorting box 2, and finally the color is distinguished in the color selection box 210 below the sorting box 2. Through the detachable and replaceable sorting structure, different waste plastic sorting needs can be easily adapted, whether it is for a specific type of plastic, or for different sizes or shapes of plastic fragments, the appropriate sorting structure can be replaced to achieve it, and when the sorting structure fails or wears out, due to its detachability, maintenance personnel can quickly repair or replace it, thereby prolonging the service life of the equipment, so as to solve the problem that the existing crushing and sorting device mostly adopts a fixed structure, which may not be convenient to disassemble and replace, may make the equipment unable to adapt to different types or different requirements of waste plastic treatment needs, and may cause failure to be discovered and processed in time, thereby increasing the failure rate of the equipment.
