That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a high-efficiency garbage shredder of the utility model comprises a crushing box 2, wherein a plurality of driving rollers are installed inside the crushing box 2, a plurality of shredder blades are installed on the driving rollers, and the shredder blades are staggered and arranged respectively, a feed hopper 1 is installed at the upper end of the crushing box 2, a frame 3 is installed at the lower end of the crushing box 2, and the shredder blades are composed of a knife disc 4 and a plurality of cutting heads 5, both sides of the knife disc 4 are recessed to form a connecting groove 12 of an annular structure, a plurality of cutting heads 5 are evenly distributed on the outer ring surface of the knife disc 4 in an annular structure, a plurality of connecting plates 13 are installed on the inner side surface of the cutting head 5, the connecting plates 13 are inserted into the connecting groove 12, and a positioning groove 14 is provided at the outer ring surface of the connecting groove 12 facing the connecting plate 13, a positioning block 6 is installed at one end of the connecting plate 13, the positioning block 6 is inserted into the connecting groove 12, and a locking ring 7 for pressing and fixing the connecting plate 13 is installed in the connecting groove 12.

[0024] In this embodiment, the outer ring surface of the connecting groove 12 is provided with an external thread, the inner ring surface of the locking ring 7 is provided with an internal thread, the locking ring 7 is connected to the external thread on the connecting groove 12 through the internal thread, and the inner side surface of the locking ring 7 is in contact with the outer side surface of the connecting plate 13;

[0025] The connection between the locking ring and the connecting groove is facilitated by the threaded connection, so that the connecting plate can be clamped and fixed.

[0026] In this embodiment, a plurality of first limit grooves 8 are provided on the outer side surface of the locking ring 7, and a second limit groove 9 connected to the outer side surface of the cutter disc 4 is provided opposite to the first limit groove 8, and a limit block 10 is provided in the first limit groove 8 and the second limit groove 9 opposite to each other. A first screw hole is provided on the inner wall surface of the second limit groove 9, and a groove is provided on the outer side surface of the limit block 10 opposite to the first screw hole, and a second screw hole connected to the first screw hole is provided on the inner wall surface of the groove, and a bolt 11 is threadedly connected in the first screw hole and the second screw hole opposite to each other, and the head of the bolt 11 is hidden in the groove, and the outer side surfaces of the limit block 10, the locking ring 7, the cutter disc 4 and the cutting head 5 are all flush.

[0027] In this embodiment, the inner side surface of the connecting plate 13 is disposed in abutment with the inner wall surface of the connecting groove 12, so that the connecting plate can be tightly disposed in abutment with the locking ring and the connecting groove to ensure the firmness of the clamping.

[0028] In this embodiment, a discharge port is provided below the crushing box 2 so that the crushed garbage can be discharged outwards through the discharge port.

After the fixing of the bolt is lost, the limit block can be taken out from the first limit groove and the second limit groove. After the blocking of the limit block is lost, the locking ring can be rotated along the thread until the locking ring is taken out from the connecting groove. After the blocking of the locking ring is lost, the cutting head can be directly removed from the cutter disc, which greatly facilitates its replacement and reduces the maintenance cost.

[0031] During installation, the cutting head can be placed on the outer ring surface of the cutter disc, the connecting plate can be inserted into the connecting groove, and the positioning block can enter the positioning groove. After the locking ring is threadedly connected in the connecting groove, the locking ring can move inward and clamp the connecting plate inwardly and fix it in the connecting groove, while the inner ring surface of the locking ring contacts the outer ring surface of the positioning block. The positioning block, the connecting block and the cutting head can be positioned through the locking ring, thereby preventing the cutting head from moving outward.

[0032] Among them, in order to increase stability, the limit block can be placed in the first limit groove and the second limit groove and fixed by bolts. The limit block can position the locking ring, avoiding the locking ring from rotating and increasing stability.

[0033] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
