Description

Technical Field

[0001] This utility model relates to the field of shredder technology, specifically to a dual-shaft shredder. Background Technology

[0002] A shredder is a machine used for coarse crushing, generally for processing unprocessed raw materials or scraps in the recycling industry, making them smaller in size. Compared with other crushers, it has a lower shaft speed, lower noise, and lower energy consumption. During operation, the shredder typically uses blades on the outer wall of the cutter shaft to shred the material. Existing shredder cutters usually rely on the sharp points on their surfaces to enhance the shredding effect. However, this structure presents challenges during operation. When the cutter breaks or during assembly, it is inconvenient for the operator to replace or reassemble the cutter, increasing the time spent on assembly or replacement and reducing the practicality of the shredding assembly. Therefore, a dual-shaft shredder is proposed to address these issues. Utility Model Content

[0035] Working principle:

[0036] A material storage box 2 is provided in the middle of the shredding host 1, and a shredding component 3 is provided inside the material storage box 2. At the same time, a rectangular rod 5 provided inside the shredding component 3 is fitted with an integral blade composed of a first blade 6 and a second blade 7. A first insert 8 is provided on the end face and the bottom of the first blade 6, and the first insert 8 is inserted into the second slot portion 702 provided on the end face and the bottom of the second blade 7. A second insert 9 is provided on the end face and the bottom of the second blade 7, and the second insert 9 is inserted into the first slot portion 602 provided on the end face and the bottom of the first blade 6. In this way, the end face of the first blade 6 and the end face of the second blade 7 are in contact, and the first blade 6 and the second blade 7 are completely merged. A semi-circular limiting block 13 is provided in both the first blade 6 and the second blade 7, and the semi-circular limiting block 13 is locked in the arc-shaped stop block 12 and can rotate.

Springs 15 are provided between the inner walls of the blades 7. When the first blade 6 and the second blade 7 are connected, the first insert block 8 and the second insert block 9 push the semicircular limiting block 13 inside the other to a horizontal state, so that the first insert block 8 and the second insert block 9 can be inserted into the other. After the insertion is complete, the semicircular limiting block 13 will return to its original position due to the spring 15, and one corner of the semicircular limiting block 13 will be inserted into the arc-shaped stop block 12 of the other, so that the two are hooked together. At the same time, the same structure is provided on both sides of the first blade 6 and the second blade 7, so that the connection between the first blade 6 and the second blade 7 is more secure. The first U-shaped opening 601 and the second U-shaped opening 701 provided in the middle of the first blade 6 and the second blade 7 respectively fit the rectangular rod 5, which fits the shape of the rectangular rod 5 perfectly. After the rectangular rod 5 is rotated by the rotating shaft 4, the first blade 6 and the second blade 7 also rotate to perform the tearing work.

[0037] Furthermore, when the first blade 6 and the second blade 7 need to be replaced or repaired, the lever 14 can be manually driven to make the semicircular limit block 13 tend to be horizontal, and the semicircular limit block 13 can be disengaged from the arc-shaped stop block 12 of the other side, so that the first blade 6 and the second blade 7 can be separated.
