[0008] A mounting groove is provided between the extension portion and the positioning boss, and a fixed knife body is provided inside the mounting groove.

[0009] Preferably, a plurality of mounting holes 1 are provided at equal distances on a side of the fixed blade seat body away from the positioning boss;

[0010] Preferably, the first mounting hole is a stepped hole;

[0011] Preferably, a second mounting hole is formed through the middle of the fixed blade body, and a third mounting hole matching the second mounting hole is formed in the middle of the extension portion.

[0012] Preferably, the fixed blade body is made of high-strength alloy;

[0013] Preferably, the fixed blade seat body is in the shape of a cuboid, and the fixed blade body is in the shape of a cube.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This single-shaft shredder uses a fixed knife and a fixed knife seat. Positioning bosses are provided on both sides of the mounting groove of the fixed knife seat body, and positioning grooves are provided on both sides of the fixed knife body to match the fixed knife body. The cooperation between the positioning bosses and the positioning grooves can ensure that the fixed knife body can be accurately positioned on the fixed knife seat body during installation without installation deviation.

[0016] 2. The fixed blade and fixed blade seat used in this single-shaft shredder have a mounting hole 1 in the middle of the extension part, which is used to connect the fixed blade seat body to the frame of the shredder, ensuring that the fixed blade seat body can be firmly installed on the frame and will not loosen or shift during operation.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1-2 As shown, the utility model provides a technical solution:

[0022] A fixed knife and a fixed knife seat for a single-shaft shredder, comprising a fixed knife seat body 1, an extension portion 2 being provided below one side of the fixed knife seat body 1, a plurality of positioning bosses 3 being equidistantly provided at the front end of the fixed knife seat body 1, a mounting groove 4 being provided between the extension portion 2 and the positioning boss 3, a fixed knife body 5 being provided inside the mounting groove 4, a plurality of mounting holes 1 6 being equidistantly provided on a side of the fixed knife seat body 1 away from the positioning boss 3, the mounting holes 1 6 being stepped holes, a mounting hole 2 7 being penetrated through the middle of the fixed knife body 5, a mounting hole 3 8 being provided in the middle of the extension portion 2 matching the mounting hole 2 7, the fixed knife body 5 being made of a high-strength alloy having good wear resistance and hardness, the fixed knife seat body 1 being in the shape of a rectangular parallelepiped, and the fixed knife body 5 being in the shape of a cube;

[0023] In this embodiment, a mounting hole 6 is provided in the middle of the extension portion 2 for connecting the fixed blade holder body 1 to the frame of the shredder, thereby ensuring that the fixed blade holder body 1 can be firmly mounted on the frame and will not become loose or shifted during operation.

[0024] Positioning bosses 3 are provided on both sides of the mounting groove 4 of the fixed knife seat body 1, and positioning grooves matching the fixed knife body 5 are provided on both sides of the fixed knife body 5. Through the cooperation of the positioning bosses 3 and the positioning grooves, it can be ensured that the fixed knife body 5 can be accurately positioned on the fixed knife seat body 1 during the installation process, and no installation deviation will occur.

[0025] Working principle: When in use, first place the fixed knife body 5 in the mounting groove 4 at the front end of the fixed knife seat body 1, and make the bottom end of the fixed knife body 5 abut against the upper end surface of the extension part 2, and then use bolts to fix the mounting hole 2 7 and the mounting hole 3 8 between the fixed knife body 5 and the extension part 2, and then fix the fixed knife seat body 1 to the frame of the shredder with bolts. When fixing, use the bolt to pass through the mounting hole 1 6 and thread it with the hole groove of the shredder frame to achieve fixation. When the fixed knife body 5 needs to be replaced or maintained, just loosen the bolts inside the mounting hole 2 7 and the mounting hole 3 8 to remove the fixed knife body 5 from the fixed knife seat body 1.
