[0026] The supporting box body 3 is covered on the first crushing assembly 1 , and a feeding opening 30 is opened at the bottom of the supporting box body 3 .

[0027] It can be understood that, by providing the discharge port 30 at the bottom of the supporting box 3 , it is convenient for the second crushing assembly 4 to discharge the screened materials from the discharge port 30 to the conveyor 5 .

[0028] It should be noted that the support box 3 described in this embodiment is cylindrical or has an inclined bottom, so as to ensure that the second crushing assembly 4 discharges the screened material from the discharge port 30 to the conveyor 5.

[0029] The second pulverizing assembly 4 may include a second housing 40 , a second motor 41 , a cutting mechanism 42 and an agitating member 43 .

[0030] The second box body 40 is disposed in the supporting box body 3 , a plurality of screening holes 400 are provided on the second box body 40 , and the other end of the spiral conveying assembly 2 is in communication with the second box body 40 .

[0031] It is understandable that by opening a plurality of screening holes 400 on the second box body 40 , materials meeting the crushing specifications leak out from the screening holes 400 into the supporting box body 3 and are discharged from the discharge port 30 on the supporting box body 3 onto the conveyor 5 .

[0032] The second motor 41 is disposed on the supporting box 3 , and the output shaft of the second motor 41 is connected to the cutting mechanism 42 . The cutting mechanism 42 is rotatably disposed on the second box 40 and the supporting box 3 .

[0036] Specifically, during the actual operation, the relevant staff puts the material into the first crushing component 1 for crushing. The crushed material falls into the spiral conveying component 2 and is transported to the second box body 40 through the spiral conveying component 2. The second motor 41 drives the cutting tool 421 to fully crush the material. The material that meets the specifications is screened out from the screening hole 400 on the second box body 40, and falls into the supporting box body 3, and is discharged from the discharge port 30 to the conveyor 5. In addition, the rotation of the spiral conveying component 2 drives the stirring member 43 to rotate in the second box body 40, thereby accelerating the leakage of the material that meets the specifications from the screen, thereby improving the crushing efficiency of the device.

[0037] In one embodiment of the present invention, Figure 4 As shown, the cutting mechanism 42 may include a rotating shaft 420 and a cutting tool 421 .

[0051] Specifically, during the actual operation, the relevant staff puts the material into the first box body 10, and the first motor 12 drives the squeezing roller 13 to extrude and crush the material. The crushed material falls into the conveying cylinder 20 from the discharge port 101, and the third motor 21 drives the auger 22 to rotate to convey the material to the second box body 40. In the process of conveying, the fully crushed material falls from the screening hole 400 opened on the conveying cylinder 20 into the supporting box body 3 and falls onto the conveyor 5 from the discharge port 30. The second motor 41 drives the cutting tool 421 to fully crush the material entering the second box body 40. The material that meets the specifications is screened out from the screening hole 400 on the second box body 40 and falls into the supporting box body 3, and is discharged from the discharge port 30 to the conveyor 5. In addition, the rotation of the auger 22 drives the stirring member 43 to rotate in the second box body 40, thereby accelerating the leakage of the material that meets the specifications from the screen, thereby improving the secondary crushing efficiency of the second crushing component 4.

[0052] In summary, the waste crushing device of the embodiment of the present invention adopts the setting of secondary crushing and screening, which can fully crush plastic waste, thereby reducing the labor intensity of workers and improving the crushing efficiency of the device for plastic waste.
