The outer wall of the body is connected to a nozzle, and the nozzle is connected to the inside of the body. The two ends of the body are a feed port and a discharge port, and the feed port and the discharge port are both connected with a dust curtain by bolts, and the dust curtain is composed of a plurality of elastic strip-shaped dust strips. When the steel structure is rusted, the steel structure is hoisted on a conveyor vehicle, and then the conveyor vehicle is ordered to transport the steel structure into the body along the length direction of the track, and the nozzle on the outer wall of the body is used to blast sand into the body, and the sand and gravel are sprayed on the surface of the steel structure to hit the rust on the surface of the steel structure, so that the rust on the surface of the steel structure can be removed.

[0042] When in use, after removing the damaged dust shield strip 4, it is necessary to replace the new dust shield strip 4. The specific operation is shown in Example 3. After completing the replacement of the dust shield strip 4, it is necessary to manually hold the pull handle 10 to drive the connecting frame plate 7 to move. First, the dust shield strip 4 is inserted into the inner cavity 13. The set dust shield strip 4 will continuously contact the movable ball 14, and the movable ball 14 will roll, which can provide support for the movement of the dust shield strip 4 and improve the smoothness. As the dust shield strip 4 is continuously inserted, the set guide rod 20 will be correspondingly inserted into the guide hole 28, and the slide bar 12 will be embedded in the slide groove 27 and continue to slide, thereby The connection between 29 and the slot 21 provides pre-alignment to ensure that the plug plate 29 is firmly inserted into the slot 21. At the same time, the push plate 9 needs to be manually pulled so that the limit plate 17 is pulled out of the guide slot 22. At this time, the side rod 16 will move at the same time, and the spring 15 will be stretched. The spring 15 will store elastic potential energy to maintain the state of the limit plate 17 at this time. Then, through continuous pushing, the plug plate 29 will be directly inserted into the slot 21. Then, release the push handle, and under the rebound action of the spring 15, the limit plate 17 will automatically insert into the guide slot 22 and the lock slot 30 to achieve the limitation of the added frame plate, thereby realizing the installation of the dust barrier strip 4.

[0043] Embodiment 3: On the basis of embodiment 2, the connecting frame plate 7 is L-shaped, a handle 10 is fixed to the bottom of the connecting frame plate 7, the limiting component 11 includes an outer frame 25, a rectangular block 34, a rubber block 33, a rotating plate 24 and an elastic rubber band 38, the outer frame 25 is fixed to the side of the back frame 23, a cavity 32 is opened on the surface of the outer frame 25, a rubber block 33 is fixed on the inner wall of the cavity 32, a plurality of rubber blocks 33 are provided, and the plurality of rubber blocks 33 are evenly distributed on the inner wall of the cavity 32, a through groove 39 is opened through the surface of the back frame 23, the through groove 39 is located in the cavity 32, four groups of through grooves 39 are provided, and the four groups of through grooves 39 are evenly distributed in a circular shape in the cavity 32, and a rectangular block 34 is provided in the through groove 39, Elastic rubber bands 38 are fixed on the outer walls of the four sides of the rectangular block 34, one side of the elastic rubber band 38 is fixedly connected to the inner wall of the through groove 39, both sides of the end surface of the rectangular block 34 are chamfered, the rotating plate 24 is rotatably connected to the back frame 23, the rotating plate 24 is located in the cavity 32, a concave area 35 is provided on the surface of the rotating plate 24, the rectangular block 34 can extend from the concave area 35, the concave area 35 is provided in four groups, and the four groups of concave areas 35 are equidistantly distributed on the rotating plate 24, an extension plate 36 is provided between the two concave areas 35, the extension plate 36 can abut against the rectangular block 34, a groove 37 is provided on the outer surface of the extension plate 36, the rubber block 33 can be embedded in the groove 37, and a turning handle 3 is fixed on the surface of the rotating plate 24;

[0044] When in use, after the damaged dust shield strip 4 is pulled out from the accommodating groove 31, a new dust shield strip 4 is inserted into the accommodating groove 31, and then, by turning the turning handle 3, the rotating plate 24 is driven to rotate, thereby moving the extension plate 36, and the extension plate 36 presses the rectangular block 34. The two sides of the end surface of the rectangular block 34 are chamfered to improve the smoothness when pressing. As the extension plate 36 completely covers the rectangular block 34, the rectangular block 34 will be completely inserted into the through groove 39 and press against the outer wall of the dust shield strip 4, so as to limit the dust shield strip 4. The rubber blocks 33 are alternately embedded in the grooves 37 when the rotating plate 24 is rotated. At the same time, the cooperation between the rubber blocks 33 and the grooves 37 can provide resistance to prevent the rotating plate 24 from automatically rotating under the action of external force and causing the dust barrier strip 4 to loosen. After the rectangular block 34 is inserted into the through groove 39, the elastic rubber band 38 is stretched, and the elastic rubber band 38 stores elastic potential energy, so that when the concave area 35 moves above the rectangular block 34, the rectangular block 34 will automatically extend from the concave area 35.

When replacing the dust barrier strip 4, by turning the turning handle 3, the rotating plate 24 will be driven to rotate, so that the extension plate 36 is moved away from the rectangular block 34, so that the rectangular block 34 is removed from the concave area. 35 extends out, so that the rectangular block 34 cancels the state of pressing against the dust barrier strip 4, which facilitates the removal of the dust barrier strip 4. After the damaged dust barrier strip 4 is pulled out from the mounting groove 31, a new dust barrier strip 4 is inserted into the mounting groove 31. Then, by turning the turning handle 3, the rotating plate 24 is driven to rotate, so that the extension plate 36 moves, and the extension plate 36 presses the rectangular block 34. The two sides of the end surface of the rectangular block 34 are chamfered to improve the smoothness when pressing. As the extension plate 36 completely covers the rectangular block 34, the rectangular block 34 will be completely inserted into the through groove 39 and press against the dust barrier strip 4 The outer wall of the dust barrier strip 4 is used to limit the dust barrier strip 4. When the dust barrier strip 4 is replaced, the handle 10 needs to be manually held to drive the connecting frame plate 7 to move. First, the dust barrier strip 4 is inserted into the inner cavity 13. The dust barrier strip 4 will continuously contact the movable ball 14, and the movable ball 14 will roll, which can provide support for the movement of the dust barrier strip 4 and improve the smoothness. As the dust barrier strip 4 is continuously inserted, the guide rod 20 will be correspondingly inserted into the guide hole 28, and the slide bar 12 will be embedded in the slide groove 27 and continue to slide, thereby connecting the plug plate 29 and the slot 21. Pre-alignment is provided to ensure that the plug plate 29 is firmly inserted into the slot 21. At the same time, the push plate 9 needs to be manually pulled so that the limit plate 17 is pulled out of the guide slot 22. At this time, the side rod 16 will move at the same time, and the spring 15 will be stretched. The spring 15 will store elastic potential energy to maintain the state of the limit plate 17 at this time. Then, through continuous pushing, the plug plate 29 will be directly inserted into the slot 21. Then, release the push handle, and under the rebound action of the spring 15, the limit plate 17 will automatically insert into the guide slot 22 and the lock slot 30 to achieve the limitation of the added frame plate, thereby realizing the installation of the dust guard strip 4.
