The barrel 11 is provided with a shot feeding pipe 14 for feeding the shot in the feeding bin 30 into the barrel 11 and a shot discharging pipe 15 for feeding the shot pushed by the pushing screw 12 into the centrifugal blasting disk 20, the shot discharging pipe 15 is positioned above the shot feeding pipe 14, and the shot feeding pipe 14 and the shot discharging pipe 15 are respectively inclined relative to the barrel 11 in the directions close to each other. Specifically, in fig. 2 and 3, the shot discharging pipe 15 and the shot feeding pipe 14 are offset from each other in the circumferential direction of the barrel 11, providing a sufficient position for arrangement between the centrifugal blast disk 20 and the bin 30; the shot blasting feeding pipe 14 is a conical pipe which is arranged in a gradually increasing manner along the direction away from the cylinder 11, so that the shot blasting in the bin 30 can be further ensured to automatically drop into the cylinder 11 along the shot blasting feeding pipe 14; furthermore, a shot inlet pipe 14 is located below the storage bin 30, and a shot outlet pipe 15 extends into the centrifugal blasting disk 20. More specifically, in fig. 1 to 4, the end of the shot-peening pipe 14 away from the barrel 11 is provided with a flange 16, so that the shot-peening pipe 14 can be easily mounted on the bin 30 from above by means of the flange 16, thereby further ensuring that the shots in the bin 30 can smoothly fall into the barrel 11 under the action of the self-weight, and of course, the flange 16 can be deleted according to actual needs, so the invention is not limited thereto.
