After the steel pipe body 1 is fixed, a collecting cylinder is taken out and placed at the bottom of the discharge port 4. The external power supply is turned on, so that the output shaft of the cylinder 26 drives the fixed rod 17 to move downward and upward repeatedly, and the fixed rod 17 is inside the steel pipe body 1. The shot blasting balls in the lower hopper 23 can fall into the lower feeding cylinder 21 through the telescopic tube 16 and enter the shot blasting device 22 through the feeding cylinder 21, and further throw the shot blasting balls onto the inner wall of the steel pipe through the shot blasting holes 15 inside the shot blasting device 22 to clean the inner wall of the steel pipe. At this time, the shot blasting balls fall into the collecting cylinder through the discharge port 4. At this time, the fixed rod 17 moves downward and upward repeatedly to drive the dust collector 25, and through the cooperation of the telescopic tube 21, the dust suction disc 20 and the dust suction pipe 19, the dust generated during shot blasting is concentrated and sucked into the dust collector 25 to complete the cleaning of the inner wall of the steel pipe.
