The intercepted impurity debris will fall to the bottom of the collecting box 3 under the action of its own gravity to be collected;

[0049] The airflow discharged from the exhaust pipe 6 is transported to the blowing pipe 8 and blown out, so that the debris generated during the cutting process can be blown away, so that the generated debris can be better blown into the collecting bucket 2, thereby improving the collection effect of the debris generated during the cutting process of the spring 25 steel;

[0050] During this process, the drive motor 10 is started, and the drive motor 10 can control the rotating shaft 9 to drive the scraper 11 to rotate.

The discharge motor 14 can control the spiral discharge shaft 13 to rotate, and the spiral discharge shaft 13 can discharge the debris entering the discharge box 12 evenly and stably.

[0053] In this process, the external water is transported to the spray pipe 16 and sprayed outwardly onto the debris through the atomizing nozzle 17 on the spray pipe 16, so that the surface of the debris is atomized, thereby preventing the secondary dust from occurring when the debris is removed.

[0054] A conveyor belt structure may be provided at the rear end of the discharge box 12 to timely convey the discharged debris away.
