[0030] In an alternative embodiment of the present invention, as Figure 9 shown, the lifting assembly includes: a stepping motor IV 21, a rack 22, a leak plate 23, and a baffle III 24. The stepping motor IV 21 is fixedly installed on the top of the cleaning box 15. The motor gear of the stepping motor IV 21 meshes with the rack 22. The rack 22 is slidably installed in the notch on the top of the cleaning box 15. The lower end of the rack 22 is rotatably connected to the hinge seat on the leak plate 23. A convex shaft is provided on the side of the leak plate 23. The convex shaft is slidably installed in the chute on the inner wall of the cleaning box 15. The leak plate 23 is provided with water leakage holes. The baffle III 24 is slidably installed in the chute on the inner wall of the cleaning box 15.

[0031] In an alternative embodiment of the present invention, as Figure 7 shown, there are three crushing blades 13, and the length of each crushing blade 13 is different, increasing in order, so that the contact area with the plastic product becomes larger and larger, gradually increasing the crushing density, enabling the plastic product to be crushed step by step.

[0032] Working principle: When the present invention is in use, plastic waste is conveyed through the feeding rack 1. The feeding rack 1 is provided with an inclined plane and can move slowly through the vibration mechanism. The stepping motor I 8 is started to drive the turntable 10 to rotate. Through the transmission shaft I 9, the turntables 10 on both sides can rotate synchronously, so that the eccentric shafts on the turntables 10 drive the vibration plate 7 to vibrate up and down. When the plastic waste passes through the baffle I 2, it will be squeezed to the middle to prevent the mixture from directly falling into the storage box 5. When passing through the baffle II 3, the air jet head 4 provided on the baffle II 3 sprays high-pressure air, which can blow the relatively lighter plastics into the storage box 5, and impurities such as heavy metals and soil blocks will continue to slide downward and fall to the collection place.

[0033] When a certain amount of plastic products has accumulated in the storage box 5, the partition 6 is pulled outwards to make the plastic products fall into the pipeline 11. Then the partition 6 is closed and waited to be opened again after being filled up again, forming intermittent feeding. The stepping motor II 14 is started, and the transmission shaft II 12 is driven to rotate through the reduction box, so that the crushing blades 13 rotate. The plastic products will successively pass through the crushing blades 13 from short to long, and the crushing degree becomes stronger and stronger, being crushed step by step and more evenly.

[0034] When the crushed debris falls into the cleaning box 15, water is injected at the water injection port 16. Then the stepping motor III 17 is started to drive the driven gear 18 to rotate, so that the internal stirring wheel 20 rotates. The stirring wheel 20 will drive the water in the cleaning box 15 to stir, so as to clean the debris. After the cleaning is completed, the stepping motor IV 21 is started to drive the rack 22 to slide upwards. The rack 22 drives the leak plate 23 to slide upwards. The leak plate 23 will slide in the chute on the inner wall of the cleaning box 15. The debris on the leak plate 23 will be taken up, and the water will leak down. When sliding to the upper end, it will be forced to turn with the turning of the chute, so that the leak plate 23 is inclined, and the debris will fall onto the discharge chute 19; while the leak plate 23 is rising, the leak plate 23 will catch the short shaft on the baffle III 24, so as to drive the baffle III 24 to slide upwards, so that the drain port blocked by the baffle III 24 is exposed, and the sewage is discharged. When the leak plate 23 is reset, the baffle III 24 will block the drain port again, and at the same time, the water injection port 16 continues to inject water, waiting for the next cleaning.

[0035] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
