[0025] The specific implementation process of the utility model is as follows: When in use, the specific operation mode of the electric vibrating feeder has been disclosed in the utility model patent with patent authorization announcement number CN214988356U, and will not be repeated here.

[0026] During the screening process of the screening box 2, the air pump 81 works at the same time.
