[0028] When the sandblasting abrasive needs to be recycled, the abrasive is sprayed onto the surface of the object to be processed through the spray pipe 6 and the spray port 7, and the impacted abrasive and the waste on the surface of the processed object fall to the upper part of the bottom plate 1, and the second motor 20 is started to drive the second motor 20 to rotate the threaded rod 9 at the output end, and the rotation of the threaded rod 9 drives the threaded sleeve 10 to slide on the inner side of the limit plate 12, and the movement of the threaded sleeve 10 drives the scraper plate 11 to slide on the upper part of the bottom plate 1, so that the abrasive and the waste on the surface of the processed object fall into the recycling box 8, so as to clean the abrasive on the bottom plate 1 and the waste on the surface of the processed object.

[0029] Reference Figure 3-4The screening assembly includes a mounting plate 13, a first motor 14, a rotating rod 15, a mounting block 16, a limiting shaft 17, a screening net 18 and a cam 19. The mounting plate 13 is fixedly connected to the lower left side of the recycling box 8, the first motor 14 is fixedly connected to the lower part of the mounting plate 13, the rotating rod 15 is fixedly connected to the output end of the first motor 14, the mounting block 16 is fixedly connected to the inner walls on both sides of the recycling box 8, the limiting shaft 17 is fixedly connected to the upper part of the mounting block 16, the screening net 18 is slidably connected to the outer side of the limiting shaft 17, and the screening net 18 is limited by the limiting shaft 17.

[0031] Working principle: When the sandblasting abrasive needs to be recycled, the abrasive is sprayed onto the surface of the object to be processed through the spray pipe 6 and the spray port 7. The impacted abrasive and the waste on the surface of the processed object fall to the upper part of the bottom plate 1. The second motor 20 is started to drive the threaded rod 9 at the output end to rotate. The rotation of the threaded rod 9 drives the threaded sleeve 10 to slide on the inner side of the limit plate 12. The movement of the threaded sleeve 10 drives the scraper plate 11 to slide on the upper part of the bottom plate 1, so that the abrasive and the waste on the surface of the processed object fall to the screening On the upper part of the net 18, the abrasive and the waste on the surface of the processed object are screened by the screening net 18, and then the first motor 14 is started to make the first motor 14 drive the rotating rod 15 to rotate, and the rotating rod 15 drives the cam 19 to rotate. The rotation of the cam 19 pushes the screening net 18 to move up and down on the outside of the limit shaft 17, thereby improving the screening effect of the screening net 18, and finally pulling the handle 23 so that the handle 23 drives the box door 22 to rotate along the hinge 21, so as to facilitate the recycling of the abrasive and improve the abrasive circulation efficiency.
