One end of the air pipe 2 is connected to the water curtain dust collector 1, and the other end is connected to the first dust collecting box 4. The first dust collecting box 4 can collect impurities generated in the cutting process, and the water curtain dust collector 1 can generate negative pressure to suck the impurities in the first dust collecting box 4 through the air pipe 2. It can not only remove the impurities generated in the cutting process, but also extinguish the impurities ignited by sparks with the spray water of the water curtain dust collector 1, reducing the fire safety hazard. The adjusting mechanism 3 comprises an air door 31 and an adjusting assembly 32. The air door 31 is arranged in the air pipe 2 and connected to the adjusting assembly 32. The adjusting assembly 32 is used to adjust the angle of the air door 31 to adjust the wind power in the air pipe 2. The adjusting mechanism 3 can adjust the wind power in the air pipe 2 according to the actual situation, so that the dust in the impurities can enter the water curtain dust collector 1 through the air pipe 2, while the cut tobacco stays in the first dust collecting box 4. This prevents the cut tobacco from entering the spray water of the water curtain dust collector 1, avoids pollution of the spray water and the interior of the water curtain dust collector 1, reduces the replacement cycle of the spray water and the cleaning frequency of the interior of the water curtain dust collector 1, saves water resources and manpower. At the same time, the cut tobacco left in the air pipe 2 can be recycled and used, avoiding waste of cut tobacco. Moreover, the dust removal device has a simple structure and low cost.

[0040] Specifically, the air pipe 2 is welded to the water curtain dust collector 1 and the first dust collecting box 4.
