The specific structure of the shot blasting assembly 5 proposed in the device is a mature technology, and will not be described in detail herein.

When the device works, firstly, a cylindrical workpiece 10 to be derusted is fixed on an upper clamp 4, then a rotating shaft 2 is rotated, the rotating shaft 2 drives the whole hanging scaffold 3 to rotate together, and the cylindrical workpiece 10 at the lower end of the hanging scaffold 3 rotates along with the hanging scaffold 3 by taking the axis of the rotating shaft 2 as a reference;

in the process, when the cylindrical workpiece 10 rotates to a position close to the output port of the shot blasting assembly 5, the rotation of the rotating shaft 2 is stopped, the shot blasting assembly 5 works, a shot is output from the output port of the shot blasting assembly 5, the shot is beaten on one side of the cylindrical workpiece 10, and the impact force of the shot is utilized to impact one side of the cylindrical workpiece 10;

the acting force of the projectile drives the cylindrical workpiece 10 to rotate at this time, and the continuous impact force of the projectile can enable the cylindrical workpiece 10 to continuously rotate, so that the impact force of the projectile can be converted into the power for rotating the cylindrical workpiece 10, and the rust removal operation can be uniformly performed on the outer surface of the cylindrical workpiece 10.

The middle part of the upper end of the case shell 1 is provided with a motor 6, and the output end of the motor 6 is connected with the rotating shaft 2 through a coupler.
