In one embodiment of the present invention, a vibration plate 51 is hinged to the buffer plate 5; the vibration plate 51 is fixedly connected with the buffer plate 5 through a spring; the bottom surface of the vibrating plate 51 is matched with the second groove; the during operation, the shot together drops in the second recess with the dirt piece, and make the dirt piece breakage at the striking at the second recess in-process, the shot constantly strikes on vibration board 51 with the dirt piece simultaneously, make vibration board 51 constantly the high-frequency rocking of little distance in the second recess, at the in-process that vibration board 51 rocked, first logical groove is opened to the intermittent type formula, and then make the shot intermittent type formula in the second recess get into peening pipe 21, and then avoid getting into peening pipe 21 in shot pipe more in the shot pipe quantity, can't form impact force effectively, the vibration board 51 that constantly high frequency rocked simultaneously can also effectually form thrust to shot and dirt piece, and then avoid first logical groove entry to be blockked up.

The specific working process is as follows:

when the automatic rotation type shot-blasting machine works, the rotating seat 13 is rotated, the supporting rod 14 arranged on the rotating seat 13 is inclined to different angles, then the shot-blasting machine is arranged in a pipeline, the roller 15 on the supporting rod 14 is abutted to the inner wall of the pipeline, the electric motor 16 and the air compressor 11 are started at the moment, the electric motors 16 drive the roller 15 to rotate, friction is generated between the roller 15 and the pipeline, the shot-blasting machine rotates in the pipeline under the driving of friction reaction force, the rotating speed of the electric motor 16 is adjusted, the rotating speed of the shot-blasting machine in the pipeline can be effectively adjusted, due to the inclined design between the supporting rod 14 and the roller 15 relative to the side wall of the pipeline, the self-rotating shot-blasting machine has the trend of moving in the vertical direction when rotating, and the sliding distance of the shot-blasting machine in the pipeline in a circle has certain difference according to the adjustment of the angles of the supporting rod, after the air compressor 11 is started, air is compressed and then conveyed to the inside of the pressurization cavity, then compressed air flow is utilized to drive metal shots to move upwards along the pressurization cavity, the metal shots gradually enter different shot blasting pipes 21 in the moving process and impact on the inner wall of the pipeline through the outlet of the shot blasting pipe 21 to form regular impact on a dirt layer on the inner wall of the pipeline, so that the dirt layer is broken and falls off, the metal shots impacting on the inner wall of the pipeline fall on the interception plate 22 together with broken dirt under the action of gravity, the dirt with smaller particle size falls off through the filtering holes on the interception plate 22, the dirt with larger particle size and the metal shots contact with the compressed air flow again through the conduction grooves and impact with the pipeline again under the wrapping of the compressed air flow, and further the dirt with larger particle size is broken, so that on one hand, the impact effect on the inner wall of the pipeline is enhanced, and the dirt is broken into fine particles at the same time, can make the clearance of dirt more convenient effectively, along with peening machine's continuous operation, peening machine clears up to the pipeline top gradually, cuts off the power this moment, and peening machine is landing downwards under the effect of gravity.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
