[0059] Specifically, each striking mechanism includes a striking ball 4 for hammering polyethylene and a spring 5 arranged between the striking ball 4 and the scattering roller 3;

[0073] Working principle:

[0074] When in use, the material is put in from the feed port 101, and the clumped polyethylene is broken up by the breaking up component. The broken up polyethylene falls on the conveyor belt 6. At the same time, the drying mechanism draws air under the action of the fan 7, and introduces hot air into the box body 1 through the heating of the heating tube 8 to dry the polyethylene on the conveyor belt 6. The water vapor and the dust particles are collected by the dust removal box 2. The polyethylene falls from the conveyor belt 6 onto the first sieve plate 10, and the sieved polyethylene falls onto the first discharging plate 12 and is discharged from the first discharging plate 12. The polyethylene that is not sieved falls onto the second sieve plate 11, and the sieved polyethylene falls onto the second discharging plate 13 and is discharged from the second discharging plate 13, and finally the polyethylene that is not sieved is discharged from the discharge port 18.
