[0017] Please see Figures 1-6 A double-toothed roller differential speed crusher includes a housing 1. A first speed-regulating motor 2 is fixedly connected to the surface of the housing 1. The shaft of the first speed-regulating motor 2 passes through the inner cavity of the housing 1 and is fixedly connected to a first crushing roller 3. A first U-shaped plate 4 is movably connected to the surface of the housing 1. A second speed-regulating motor 5 is fixedly connected to the surface of the first U-shaped plate 4. The shaft of the second speed-regulating motor 5 passes through the first U-shaped plate 4 and the housing 1 respectively and is fixedly connected to a second crushing roller 6. A second U-shaped plate 7 is fixedly connected to one side of the housing 1. A drive motor 8 is fixedly connected to the surface of the second U-shaped plate 7. A threaded rod 9 is fixedly connected to the shaft of the drive motor 8. The end of the rod 9 away from the drive motor 8 passes through the second U-shaped plate 7 and is threadedly connected to the second U-shaped plate 7. By setting up the housing 1, the first speed-regulating motor 2, the first crushing roller 3, the first U-shaped plate 4, the second speed-regulating motor 5, the second crushing roller 6, the second U-shaped plate 7, the drive motor 8, and the threaded rod 9, the speed of the first speed-regulating motor 2 and the second speed-regulating motor 5 can be independently controlled and adjusted, thereby controlling the speed of the first crushing roller 3 and the second crushing roller 6. When encountering large pieces of material that are difficult to crush, the crushing frequency is increased, so that large pieces of coke can be crushed more fully, thereby effectively improving the crushing effect and ensuring that the particle size of the crushed coke meets the requirements.

[0018] Please see Figure 5 A guide rod 10 is fixedly connected to the inner wall of the second U-shaped plate 7. The end of the guide rod 10 away from the second U-shaped plate 7 passes through the first U-shaped plate 4 and is fixedly connected to the box body 1. The guide rod 10 is movably connected to the first U-shaped plate 4. The guide rod 10 plays a guiding and stabilizing role, ensuring the straightness and smoothness of the movement of the first U-shaped plate 4, preventing it from deviating or shaking during the movement, thereby ensuring the accuracy of the position adjustment of the second crushing roller 6 and improving the stability and reliability of the equipment operation.

[0019] Please see Figure 5Guide holes 11 are provided on both sides of the housing 1. The shaft of the second speed-regulating motor 5 passes through the guide hole 11 and is movably connected to the guide hole 11. The left side of the second crushing roller 6 passes through the guide hole 11 through the rotating rod and is movably connected to the first U-shaped plate 4. The guide hole 11 guides the second crushing roller 6, ensuring the normal rotation and movement of the shaft of the second speed-regulating motor 5 and the rotating rod on the surface of the second crushing roller 6, preventing them from moving excessively or deviating from the normal working position, and ensuring the normal operation of the crusher.

[0020] Please see Figures 3-6 A dust collection mechanism 12 is installed on the surface of the box 1. The dust collection mechanism 12 includes a dust collection pipe 120. The top of the dust collection pipe 120 is fixedly connected to the top of the inner wall of the box 1. The bottom of the dust collection pipe 120 is connected to a connecting pipe 121. The top of the connecting pipe 121 passes through the box 1 and is connected to a dust collection box 122. The bottom of the dust collection box 122 is connected to an exhaust fan 123. During the crushing process, the exhaust fan 123 generates negative pressure, which causes the dust in the box 1 to enter the dust collection box 122 through the dust collection pipe 120 and the connecting pipe 121. This effectively reduces the dust generated during the crushing process, improves the working environment, reduces the harm of dust to the health of operators, and also meets environmental protection requirements.

[0021] Please see Figure 6 The right sides of the dust collection box 122 and the exhaust fan 123 are both fixedly connected to the housing 1. The inner cavity of the dust collection box 122 is provided with a vent frame 124. One side of the vent frame 124 extends through to the outside of the housing 1 and is movably connected to the housing 1. A handle is fixedly connected to the surface of the vent frame 124. The vent frame 124 can block dust from entering the exhaust fan 123 while allowing air to pass through, ensuring the normal operation of the dust collection mechanism 12. When a lot of dust accumulates in the dust collection box 122, the operator can easily pull out the vent frame 124 through the handle to clean the dust in the dust collection box 122, which improves the ease of maintenance of the equipment.

[0022] Please see Figure 6 A pad 125 is fixedly connected to the inner wall of the dust collection box 122. The top of the pad 125 contacts the vent frame 124. The pad 125 provides stable support for the vent frame 124, preventing the vent frame 124 from shaking or shifting due to vibration during equipment operation, and ensuring the sealing and stability between the vent frame 124 and the dust collection box 122.

[0023] Please see Figures 1-6The top of the box 1 is connected to the feed pipe 13, and the bottom of the box 1 is connected to the discharge pipe 14. The four corners of the bottom of the box 1 are fixedly connected to the support legs, and the inner wall of the box 1 is fixedly connected to the guide plate 15. The support legs provide stable support for the entire equipment, ensuring the stability of the equipment during operation and reducing vibration. The guide plate 15 can guide the coke entering the box 1 to flow smoothly to the crushing roller, improve the feeding efficiency, and at the same time, it can also prevent the coke from accumulating in the box 1 to a certain extent, ensuring the continuity and stability of the crushing process.

[0024] In use, coke enters the inner cavity of the box 1 through the feed pipe 13. The first speed-regulating motor 2 is controlled by the external controller to drive the first crushing roller 3 to rotate, and the second speed-regulating motor 5 is controlled to drive the second crushing roller 6 to rotate. The speed of the first speed-regulating motor 2 and the second speed-regulating motor 5 are adjusted according to the size of the coke particles, and the speed of the first crushing roller 3 and the second crushing roller 6 are also adjusted to facilitate the crushing of coke particles of different sizes. By controlling the drive motor 8 to rotate the threaded rod 9, the threaded rod 9 drives the first U-shaped plate 4 to move, and the first U-shaped plate 4 drives the second crushing roller 6 to move. By adjusting the distance between the first crushing roller 3 and the second crushing roller 6, coke particles of different sizes can be crushed and processed. The exhaust fan 123 generates negative pressure, causing the dust inside the housing 1 to enter the ventilated frame 124 for collection through the dust suction pipe 120 and the connecting pipe 121, effectively reducing the dust generated during the crushing process.

[0025] In summary, this double-toothed roller differential speed crusher, by setting up a housing 1, a first speed-regulating motor 2, a first crushing roller 3, a first U-shaped plate 4, a second speed-regulating motor 5, a second crushing roller 6, a second U-shaped plate 7, a drive motor 8, and a threaded rod 9, solves the problem of poor crushing effect of large pieces of coke caused by the two crushing rollers rotating at the same constant speed and the fixed spacing between the crushing rollers in traditional crushing devices.
