[0026] To reduce the noise of the shot blasting machine, the first sound insulation board 2 and the second sound insulation board 3 are first fitted onto both sides of the machine body 1. Simultaneously, the retaining plate 9 on one side of the second connecting plate 7 is inserted into the retaining groove 8 opened in the first connecting plate 6, snapping the first sound insulation board 2 and the second sound insulation board 3 together. The fixing assembly then secures the retaining plate 9 within the retaining groove 8, completing the connection between the first sound insulation board 2 and the second sound insulation board 3. The first sound insulation board 2 and the second sound insulation board 3, when joined together, form a soundproof outer shell, reducing sound transmission and blocking noise propagation, thus achieving sound insulation and noise reduction. At the same time, the sound-absorbing cotton 5 placed in the groove 4 absorbs the generated noise, reducing noise transmission and reflection, achieving noise reduction; avoiding disturbance to surrounding residents and preventing complaints. It also avoids noise-induced fatigue, greatly improving the work efficiency and concentration of the staff.

[0027] The inner wall of the directional sleeve 16 is bonded with a buffer pad 17, which is made of polyurethane. The buffer pad 17, bonded to the inner wall of the directional sleeve 16, reduces the impact of steel shot on one side of the directional sleeve 16 and also reduces the noise of steel shot impacting the directional sleeve 16.

[0028] In this embodiment, the fixing component includes a circular through hole on one side of the card plate 9, a spring 12 is provided in the circular through hole, a fixing block 11 is fixedly connected to one end of the spring 12, a fixing hole 10 is provided on the first connecting plate 6, and one end of the fixing block 11 extends into the fixing hole 10.

[0029] When the card plate 9 is inserted into the card slot 8, the spring 12 in the circular through hole pushes one end of the fixing block 11 into the fixing hole 10, fixing the card plate 9 in the card slot 8, thereby connecting the first connecting plate 6 and the second connecting plate 7 together.

[0030] Meanwhile, the first connecting plate 6 is provided with bolts 13, and the clamping plate 9 is provided with threaded grooves. One end of the bolt 13 is threadedly connected to the threaded groove. By threading one end of the bolt 13 to the threaded groove, the clamping plate 9 is further fixed, and the reliability of the equipment connection is further increased.
