[0016] like Figure 1As shown, a double-shaft shredder bearing seat side plate anti-wear structure includes a body 1, a crushing groove 2 is provided on the body 1, and the crushing groove 2 is the existing conventional double-shaft shredder crushing groove. The material to be crushed can be placed into the crushing groove 2 from the top of the crushing groove 2, and can be discharged from the bottom of the crushing groove 2 after crushing. The crushing groove 2 is provided with a first rotating shaft 3 arranged in a line and a second rotating shaft 4 arranged parallel to the first rotating shaft 3. The first rotating shaft 3 and the second rotating shaft 4 adopt the conventional rotating shafts of the existing double-shaft shredder, and the cross-street surface is a regular hexagon. The side walls of the crushing groove 2 at both ends of the first rotating shaft 3 and the second rotating shaft 4 pass through, and the first rotating shaft 3 is along the first rotating shaft 4. The shaft 3 is sleeved with a plurality of first spacing sleeves 5 and a plurality of first blades 6 in the length direction. The first blades 6 are located between the first spacing sleeves 5. The first spacing sleeves 5 are used to separate the first blades 6 and limit the distance between the first blades 6. The first blades 6 adopt conventional blades of existing double-shaft shredders. The first rotating shaft 3 is also sleeved with a first wear-resistant sleeve 7. The first wear-resistant sleeve 7 is located at one end of the first rotating shaft 3 and abuts against the side wall of the crushing groove 2. The side wall of the crushing groove 2 can be protected by the first wear-resistant sleeve 7. The second rotating shaft 4 is sleeved with a plurality of second spacing sleeves 8 and a plurality of second blades 9 along the length direction of the second rotating shaft 4. The second blades 9 are sleeved with a plurality of second spacing sleeves 8 and a plurality of second blades 9 along the length direction of the second rotating shaft 4. The blade 9 is located between the second spacing sleeve 8 and the second blade 9 is staggered with the first blade 6. The arrangement and setting of the first blade 6 and the second blade 9 are the same as those of the existing double-shaft shredder. A second wear-resistant sleeve 10 is sleeved on the second rotating shaft 4. The second wear-resistant sleeve 10 is located at one end of the second rotating shaft 4 away from the first wear-resistant sleeve 7 and abuts against the side wall of the crushing groove 2. The second wear-resistant sleeve 10 can protect the other side of the crushing groove 2. The first spacing sleeve 5 can rotate with the first rotating shaft 3, and the second wear-resistant sleeve 10 can rotate with the second rotating shaft 4. In order to ensure the protection effect, the edge of the first wear-resistant sleeve 7 and the second rotating shaft 4 away from the first wear-resistant sleeve 7 are The edge of the second wear-resistant sleeve 8 at one end of the second wear-resistant sleeve 10 contacts, and the edge of the second wear-resistant sleeve 10 contacts the edge of the first wear-resistant sleeve 5 on the first rotating shaft 3 away from the end of the first wear-resistant sleeve 7. The placed object contacts the inner wall of the crushing groove 2 from the gap between the first wear-resistant sleeve 7 and the corresponding second wear-resistant sleeve 8. When crushing materials with a longer length, its two ends can respectively rest on the first wear-resistant sleeve 7 and the second wear-resistant sleeve 10 without contacting the inner wall of the crushing groove 2, thereby protecting the inner wall of the crushing groove 2. When the first wear-resistant sleeve 7 and the second wear-resistant sleeve 10 are worn, they only need to be replaced, which is convenient and quick.

One end of the second rotating shaft 4 is connected to a second motor 13 for driving the second rotating shaft 4 to rotate. The second motor 13 is connected to the second rotating shaft 4 through a second reducer 14. In order to save volume, the second motor 13 is connected to one end of the second rotating shaft 4 away from the first motor 11.

[0018] The working principle of the utility model is as follows:

[0019] When the shredder is shredding an object of a longer length, the object is placed into the crushing groove 2 along the length direction of the first rotating shaft 3, and the object is located between the first rotating shaft 3 and the second rotating shaft 4. The object is crushed by rotating the first blade 6 on the first rotating shaft 3 and the second blade 9 on the second rotating shaft 4. During the crushing process, the two ends of the object respectively abut against the first wear-resistant sleeve 7 and the second wear-resistant sleeve 10 and do not contact the inner wall of the crushing groove 2. Although the first wear-resistant sleeve 7 and the second wear-resistant sleeve 10 are in contact with the inner wall of the crushing groove 2, the contact area is large and there is no sharpness. Compared with the crushed object, the inner wall of the crushing groove 2 can be effectively prevented from being worn. The utility model can be modified by adding the first wear-resistant sleeve 7 and the second wear-resistant sleeve 10 to the existing double-shaft shredder. The structure is simple and the cost is low.
