[0003] When an existing crusher crushes an object, if the object itself contains dust, a large amount of dust will be raised under the high-speed rotation and collision. The dust is likely to affect the respiratory health of the operator, and the raised dust is also difficult to clean.

[0004] Therefore, it is necessary to propose a crusher that rotates evenly under force to solve the above problems. Utility Model Content

[0012] Technical effects and advantages of the utility model:

[0013] 1. In the actual operation of the utility model, when multiple crushing blades crush the objects inside the crushing box, a mist liquid can be sprayed through the L-shaped nozzle, so that the mist liquid can be mixed with the dust rolled up inside the crushing box, so that the dust adheres to the surface of the droplets, and the dust and the droplets fall quickly, which plays a role in reducing the dust. At the same time, the L-shaped nozzle sprays the mist liquid to cool the high-speed rotating crushing blades to avoid the problem of excessive temperature of the crushing blades.

[0014] 2. At the same time, the mist liquid can be sprayed more evenly on the crushing blades. Since the top of the L-shaped nozzle is inclined, the sprayed liquid can also be sprayed from an inclined angle, so that the liquid can fall from the top of the inside of the crushing box, thereby contacting the dust over the largest area.

[0015] 3. Furthermore, by setting up the fan, the liquid discharge speed can be increased. The wind force generated by the fan mixed with the liquid can speed up the heat dissipation of the crushing blade. At the same time, the wind force generated by the fan can be discharged in the same direction as the liquid through the tilting angle of the tilting block and the top of the L-shaped nozzle to avoid disturbing the angle of liquid spraying. In addition, after the dust and liquid are mixed, the fan can be started separately to make the wind force of the fan dry the crushing blade to avoid liquid residue on the crushing blade, affecting the subsequent use and life.

[0021] The utility model provides Figure 1 - Figure 3 The crusher shown is a crusher that rotates with uniform force, including a crushing box 1, with rotating shafts 7 rotatably connected on both sides of the short side direction inside the crushing box 1, a plurality of crushing blades 8 are fixed on the outside of the rotating shaft 7, a support frame is fixed on one side of the crushing box 1, a permanent magnet synchronous motor 3 is fixed on the support frame, and a shaft holder 4 is arranged on one side of the permanent magnet synchronous motor 3.

[0022] One side of the rotating shaft 7 extends out of the crushing box 1 , and the extended end of the rotating shaft 7 is rotatably connected in the shaft holder 4 . A driving shaft is arranged on one side of the permanent magnet synchronous motor 3 close to the rotating shaft 7 , and a dynamic balancing disk 6 is arranged on the outer side of the rotating shaft 7 .

[0023] In the actual operation of the present invention, the permanent magnet synchronous motor 3 is equipped to drive the rotating shaft 7 to rotate, and a high speed of 4000-6500 rpm can be achieved. In the case of high load, the permanent magnet synchronous motor 3 will not stall. At the same time, within the design speed range of the permanent magnet synchronous motor 3, the low speed, high speed and torque are consistent. The design of the dynamic balancing plate 6 is equivalent to adding a counterweight plate, which is convenient for dynamic balancing and can improve the dynamic balancing quality.

[0024] The driving shaft and the rotating shaft 7 are connected via a coupling 5 . The straight chain transmission has high efficiency and no wearing parts, and can make the rotating shaft 7 bear force evenly.

[0025] A discharge slot 10 is provided on one side of the long side of the crushing box 1, a fan 9 is fixed on the outside of the crushing box 1, and the air outlet of the fan 9 is connected to the discharge slot 10 accordingly. An L-shaped nozzle 11 is provided at the bottom of the discharge slot 10, and the top of the L-shaped nozzle 11 is tilted upward facing the crushing blade 8. A nozzle 12 is provided on the side of the L-shaped nozzle 11 close to the crushing blade 8. A through opening is provided on the side of the discharge slot 10 close to the fan 9, and an inclined block 14 is provided between the through opening and the L-shaped nozzle 11. The inclination angle of the top of the inclined block 14 is consistent with the inclination angle of the top of the L-shaped nozzle 11. A connecting pipe 16 is connected to one side of the L-shaped nozzle 11, and the connecting pipe 16 extends out of the crushing box 1.

[0026] In the actual operation of the present invention, when multiple crushing blades 8 crush the objects inside the crushing box 1, a mist liquid can be sprayed through the L-shaped nozzle 11, so that the mist liquid can be mixed with the dust rolled up inside the crushing box 1, so that the dust adheres to the surface of the droplets, and the dust and the droplets fall quickly, which plays a role in reducing the dust being raised. At the same time, the mist liquid sprayed by the L-shaped nozzle 11 can cool the high-speed rotating crushing blade 8 to avoid the problem of the crushing blade 8 being too hot.

[0027] At the same time, the mist liquid can be sprayed on the crushing blade 8 more evenly. Since the top of the L-shaped nozzle 11 is inclined, the sprayed liquid can also be sprayed from an inclined angle, so that the liquid can descend from the top of the inside of the crushing box 1, thereby contacting the dust over the maximum area.
