Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides Figure 1 - Figure 4 The illustrated embodiment shows a blade structure for a crusher that is easy to disassemble, comprising a rotating shaft 1 and a plurality of first sleeves 2 sleeved on the outside of the rotating shaft 1, at least three crushing blades 6 being arranged on the outer sides of the plurality of first sleeves 2, a plurality of fixing holes 5 being provided on the outer ring of the rotating shaft 1, a first embedded hole 4 corresponding to the fixing hole 5 being provided on the first sleeve 2 along the length direction, and a fixing screw being provided between the first embedded hole 4 and the corresponding fixing hole 5.

[0023] In the actual operation of the utility model, multiple first sleeves 2 can be fixedly installed on the outer ring of the rotating shaft 1 by fixing screws. Since multiple fixing holes 5 are evenly distributed around the center of the rotating shaft 1, multiple first sleeves 2 can be placed on the same horizontal plane as needed, or multiple first sleeves 2 can be installed at different angles, so that the crushing blades 6 on multiple first sleeves 2 are distributed in parallel, or the crushing blades 6 on multiple first sleeves 2 are staggered, which is convenient for adapting to different crushing environments. When the crushing blades 6 are staggered, the inputted longer objects can be cut off, improving the efficiency and application range of the crushing. At the same time, when the crushing blades 6 on a single first sleeve 2 are damaged, they can be replaced individually, saving replacement materials.

[0024] The three crushing blades 6 are evenly distributed around the first sleeve 2. Two slots 13 are provided on the side of the crushing blade 6 close to the first sleeve 2. The two slots 13 are parallel to each other. Two fixing blocks 11 are fixed on the side of the first sleeve 2 close to the slots 13. The two fixing blocks 11 are respectively engaged in the slots 13 at corresponding positions. Second embedded holes 8 are provided on both sides of the short side direction of the crushing blade 6. The two second embedded holes 8 and the two slots 13 are connected through and connected. A fixing bolt 9 is inserted and connected between the two second embedded holes 8.

[0025] In the actual operation of the utility model, the crushing blade 6 can be individually installed and disassembled on the fixed block 11, which is convenient for use.

[0026] An inclined opening 10 is fixed on one side of the crushing blade 6 away from the rotating shaft 1. The inclined opening 10 can make the end of the crushing blade 6 sharper, making it more convenient and quick to crush objects.

[0027] A plurality of heat dissipation holes 3 are provided on the three crushing blades 6 in a direction close to the first sleeve 2. The plurality of heat dissipation holes 3 and the card slot 13 are in the same plane. The plurality of heat dissipation holes 3 pass through the other side of the crushing blades 6. Saw teeth 7 are fixed on the inner walls of the plurality of heat dissipation holes 3. The plurality of heat dissipation holes 3 and the card slot 13 are distributed along the length direction of the first sleeve 2.

[0028] In the actual operation of the present invention, the crushing blade 6 generates a vortex phenomenon while rotating at a high speed, and the wind force near the end of the crushing blade 6 away from the first sleeve 2 flows in a vortex shape, and in the present invention, a plurality of heat dissipation holes 3 are opened in the direction of the three crushing blades 6 close to the first sleeve 2. When the crushing blade 6 rotates at a high speed, a part of the wind force will also flow through the heat dissipation holes 3, and this part of the wind force will flow to the end of the crushing blade 6 close to the first sleeve 2 after being blocked by the inner wall of the heat dissipation holes 3, so that the end of the crushing blade 6 close to the first sleeve 2 also has a strong vortex phenomenon, so that the wind force fully passes through the heat dissipation holes 3 to better dissipate heat for the crushing blade 6. The present invention makes good use of the setting of the heat dissipation holes 3 to suppress the vortex-shaped wind force from flowing quickly to the end of the crushing blade 6 away from the first sleeve 2, thereby increasing the heat dissipation effect of the crushing blade 6.
