One end of the first connector 1 is provided with a rotating roller seat 2, and the other end of the first connector 1 is fixedly connected to a central roller 3. One end of the central roller 3 is fixedly connected to a second connector 4. Thread grooves 12 are formed on the sides of the first connector 1 and the second connector 4. Reinforcing plates 13 are fixedly connected to the four sides of the side surface of the central roller 3. The outer surface of the first connector 1 is movably connected to a first fixing ring 14 through the thread groove 12, and the outer surface of the second connector 4 is movably connected to a second fixing ring 15 through the thread groove 12. Fixing threads 16 are formed on the inner walls of the first fixing ring 14 and the second fixing ring 15. A sealing ring 17 is arranged between the first fixing ring 14 and the second fixing ring 15. The first fixing ring 14 and the second fixing ring 15 are tightly fixed in an adaptable manner through the fixing threads 16 on the inner walls and the thread grooves 12 on the sides of the first connector 1 and the second connector 4. At this time, the sealing ring 17 between the first fixing ring 14 and the second fixing ring 15 can tightly fit and fix the two ends of the outer roller sleeve 5.

[0024] An outer roller sleeve 5 is sleeved on the outer surface of the central roller 3. Blade fixing frames 6 are fixedly connected to the four sides of the side surface of the outer roller sleeve 5. Blade bodies 7 are evenly arranged inside the blade fixing frames 6. One end of the bottom of the blade body 7 is fixedly connected to an arc-shaped plug 8. A sealing strip 9 is arranged between the blade body 7 and the arc-shaped plug 8. A socket 10 is arranged inside the arc-shaped plug 8. A fixing bolt 11 is movably connected inside the socket 10. The arc-shaped plug 8 is used for positioning and clamping with the inner bottom wall of the blade fixing frame 6, and is cooperated with the sealing strip 9 for reliable sealing and fitting at the connection part. Finally, the arc-shaped plug 8 is fastened through the fixing bolt 11 inside the socket 10, and the unified installation of multiple groups of blade bodies 7 at the blade fixing frames 6 is quickly completed.

[0025] Working principle: When in use, the user first sleeved the outer roller sleeve 5 as a whole on the first connector 1, the central roller 3 and the second connector 4. During daily operation, the rotation of the roller seat 2 can drive the whole to rotate for plastic crushing operation. And during daily use, the blade body 7 can be butted and installed inside the blade fixing frame 6 on the four sides of the side of the outer roller sleeve 5, and the arc-shaped plug 8 is used for positioning and clamping with the inner bottom wall of the blade fixing frame 6, and the sealing strip 9 is used for firmly sealing and fitting at the connection. Finally, the arc-shaped plug 8 is fastened through the fixing bolt 11 inside the socket 10, quickly completing the unified installation of multiple blade bodies 7 at the blade fixing frame 6, ensuring the stability of the subsequent plastic crushing of the whole, and also enabling the quick disassembly, replacement and maintenance of a single blade body 7 at any time.
