Rotating blocks 14 are rotatably connected to both the telescopic end of the second hydraulic rod 12 and the back surface of the other fixing plate 11. A groove 15 is provided on one side of the rotating block 14. A clamping plate 17 is slidably connected in the groove 15. A screw rod 18 is fixedly connected to the side surface of the clamping plate 17. A nut 16 is threadedly connected to the surface of the screw rod 18. An inner tube body 13 is jointly abutted between the two rotating blocks 14. A bracket 5 is fixedly connected to the upper end surface of the base 1.

A splash-proof box 4 is fixedly connected to the upper end surface of the support plate 3.

[0024] By setting the hydraulic rod, the hydraulic rod can drive the support plate 3 to move up and down. The model of the hydraulic rod is set as SYQ8 / 18-09, and the manufacturer is Changzhou Shaji Pneumatic Spring Co., Ltd.

[0025] Further, a cover plate 7 is placed on the top of the splash-proof box 4, and a recycling box 8 is placed on the upper end surface of the base 1.

[0026] Further, a discharge pipe 9 is fixedly connected to the lower end surface of the support plate 3, and the top of the discharge pipe 9 penetrates through the upper end surface of the support plate 3.

[0027] By setting the discharge pipe 9, the discharge pipe 9 can transfer the waste materials to the recycling box 8.

[0028] Further, a servo motor 10 is fixedly connected to the front surface of the fixing plate 11. The output end of the servo motor 10 penetrates through the inner wall of the fixing plate 11 and is fixedly connected to the front surface of the rotating block 14.

[0029] By setting the servo motor 10, the servo motor 10 can drive the rotating block 14 to rotate, thereby driving the inner tube body 13 to rotate.

[0030] Further, the side surface of the clamping plate 17 is slidably connected to the inner wall of the groove 15, and the shape of the side surface of the clamping plate 17 matches the shape of the inner wall of the groove 15.

[0031] By setting the clamping plate 17, the clamping plate 17 can limit the inner tube body 13 on the side of the rotating block, making it more stable.

[0033] Working principle of the utility model: First, the staff places the inner tube body 13 between two rotating blocks 14, then starts the second hydraulic rod 12 to make both ends of the inner tube body 13 abut against the surfaces of the rotating blocks 14 respectively. Then, manually adjust the clamping plate 17 to make the clamping plate 17 fit with the inner tube body 13 to complete the limiting. Then, adjust the nut 16, and the nut 16 rotates downward through the screw rod 18 to fit with the surface of the rotating block 14, thus completing the fixation of the inner tube body 13. Start the servo motor 10, and the servo motor 10 drives the rotating block 14 to rotate, thereby driving the inner tube body 13 to rotate. Then, start the hydraulic rod, and the hydraulic rod drives the bottom plate to move upward, thereby driving the splash-proof box 4 to move upward until the top end of the splash-proof box 4 abuts against the lower end surface of the cover plate 7. Then, start the sandblasting device body 6 to evenly sandblast the surface of the inner tube body 13, thus completing the sandblasting. Since both sides of the support plate 3 are inclined towards the middle with a certain slope, when there is excess waste generated by sandblasting, it can be discharged through the discharge port into the recycling box 8 for recycling and utilization;

[0034] Compared with the prior art, the workload of the staff is reduced.
