As an embodiment of the invention, a circular ring 98 with a sawtooth-shaped outer surface is sleeved on the edge of the truncated cone-shaped lower surface of the cleaning cover 9; during operation, when clean cover 9 carries out preliminary cleanness to boats and ships surface, the lower surface cup joints the clearance function that the zigzag ring can effectively strengthen clean cover 9, can clear away some intractable adhesion thing with higher speed, and when the zigzag ring had avoided clean cover 9 striking itself simultaneously, cause the peening machine vibrations, influence the output of peening pipe 5, the zigzag ring can also effectively slow down the wearing and tearing of clean cover 9 itself simultaneously, plays the effect of the service life of extension fixture.

The specific working process is as follows:

When the shot blasting machine works, the shot blasting machine is placed on the surface of a ship after being filled with shots, a controller sends out signals, and a signal receiver 4 arranged on a box body 1 receives the signals, so that the shot blasting machine is controlled; the electromagnet 71 is electrified through the controller, the electromagnet 71 arranged on the shot blasting machine generates attraction force on the metal surface of the ship, the shot blasting machine is adsorbed on the surface of the ship, meanwhile, the high-pressure air pump 52 starts to work, shots in the shot blasting pipe are sprayed on the surface of the ship along a pipeline, rust and paint on the surface of the ship are cleaned, as the gap between the control plate 7 fixedly connected to the shot blasting machine base 2 and the surface of the ship is smaller than the diameter of the shots, the sprayed shots are collected by the control plate 7 and enter the shot blasting pipe 5 again through the inclined recycling pipe 6, and the arc-shaped plate 51 fixedly connected to the junction of the recycling pipe 6 and the shot blasting pipe 5 can prevent the shots in the shot blasting pipe 5 from being sprayed into the recycling pipe 6, and the shots in the recycling pipe 6 are not influenced; the controller continuously sends out signals, the double-shaft motor 33 in the T-shaped guide rod 3 of the shot blasting machine is started to drive the roller 32 to rotate, so that the shot blasting machine is driven to advance or retreat, when the shot blasting machine cleans the surface of a ship and needs to change the direction, the controller sends out signals, the steering motor 34 works to control the T-shaped guide rod 3 to rotate, the roller 32 changes the moving direction, and the shot blasting machine is controlled to change the cleaning path; when the shot and the sundries collected in the recovery pipe 6 pass through the filter screen 61, the shot rolls and vibrates the filter screen 61, so that the sundries and the broken shot fall into the collecting tank 62; when the double-shaft motor 33 rotates, the worm wheel 91 fixedly connected to the rotating shaft also rotates to drive the worm 93 meshed with the worm wheel 91 to rotate, the movement direction of the worm wheel 91 is adjusted by the worm 93, the gear 94 is driven to rotate at a constant speed through the straight teeth arranged at one end of the worm 93, the cleaning cover 9 is driven to rotate through the mutual attraction between the first magnet block 95 and the second magnet block 96, and the outer end of the cleaning cover 9 is sawteeth for cutting sundries.

the foregoing illustrates and describes the principles, general features, and advantages of the present invention.
