DETAILED DESCRIPTION

[0021] As Figures 1-4 Indicated, the utility model provides a technical scheme: a kind of flame-retardant dust-suppression cover soil net, including shell 1, rotating shaft 3 and cover soil net body 4, rotating shaft 3 is connected rotationally through shell 1, the inside of shell 1 is provided with the control part 2 after using cover soil net body 4 to remove stain, control part 2 includes:

[0022] A connecting box 21 is fixedly connected to the surface of the housing 1 on the side closest to the housing 1. A cover 22 is fixedly connected to the inner wall of the housing 1. A rotating shaft 3 passes through the cover 22 and is rotatably connected. The soil covering net body 4 is fixedly connected to the surface of the rotating shaft 3. A handle 23 is fixedly connected to the end of the rotating shaft 3 located on the outside of the housing 1. A rotating rod 24 passes through and is rotatably connected to the inner side of the connecting box 21. Both the rotating rod 24 and the rotating shaft 3 are connected to a transmission wheel 25. Rotating the handle 23 causes the rotating shaft 3 to rotate. When the rotating shaft 3 rotates, it drives the rotating rod 24 to rotate together through the transmission wheel 25 and the transmission belt 26. At the same time, the rotating shaft 3 also rolls up the soil covering net body 4. The rotating rod 24 and the transmission wheel 25 through which the rotating shaft 3 passes are connected by the transmission belt 26. A gear 27 passes through and is fixedly connected to the rotating rod 24. There are two sets of rotating rods 24, and the gears 27 passing through the two sets of rotating rods 24 mesh with each other. A reciprocating groove 28 is formed on the surface of the rotating rod 24. A threaded sleeve 29 is threaded through and connected to the reciprocating groove 28 on the surface of the rotating rod 24. When the rotating rod 24 rotates, the bottom surface of the threaded sleeve 29 is fixedly connected to the top surface of the connecting strip 211. At the same time, the connecting strip 211 passes through the fixing plate 210 and is slidably connected, so that the reciprocating groove 28 on the surface of the rotating rod 24 will drive the threaded sleeve 29 to reciprocate. A fixing plate 210 is fixedly connected to the inner wall of the connecting box 21. A connecting strip 211 is threaded through and slidably connected to the inner side of the fixing plate 210. The top surface of the connecting strip 211 is fixedly connected to the bottom end of the threaded sleeve 29. A support rod 213 is fixedly connected to the top surface of the connecting strip 211. The support rod 213 passes through and is slidably connected to the anti-detachment frame 212. When the connecting strip 211 moves back and forth, it will abut against the upper protrusion 219 below the U-shaped frame 218, thereby forcing the connecting strip 211 to vibrate up and down under the action of the spring 216 and the anti-detachment frame 212. The cleaning brush 215 will also be inserted into the mesh of the covering net body 4 to clean the covering net body 4. The bottom surface of the anti-detachment frame 212 slides against the top surface of the fixing plate 210. A spring 216 is fixedly connected between the inner side of the anti-detachment frame 212 and the top surface of the connecting strip 211. The cleaning brush 215 is fixedly connected to the bottom surface of the connecting strip 211. When the connecting strip 211 slides back and forth in the fixing plate 210, it will also drive the cleaning brush 215 to slide back and forth, so that the covering net body 4, which passes through the connecting box 21 and is wound by the rotating shaft 3, can be scraped by the cleaning brush 215. A lower protrusion 217 is fixedly connected to the top surface of the connecting strip 211. When the connecting strip 211 reciprocates with the screw sleeve 29, the lower protrusion 217 on the top surface of the connecting strip 211 will move together with the connecting strip 211. A U-shaped frame 218 is fixedly connected to the inner wall of the connecting box 21, and an upper protrusion 219 is fixedly connected to the bottom surface of the U-shaped frame 218.

[0023] Based on the above implementation method, when the covering net body 4 is in use, the end of the covering net body 4 located outside the connecting box 21 can be directly pulled out, causing the covering net body 4 wound on the rotating shaft 3 to rotate and be pulled out, thereby covering the soil pile and other materials. After use, the handle 23 can be turned, causing the handle 23 to drive the rotating shaft 3 to rotate. When the rotating shaft 3 rotates, it will drive the rotating rod 24 to rotate together through the transmission wheel 25 and the transmission belt 26. At the same time, the rotating shaft 3 will also wind up the covering net body 4. When the rotating rod 24 rotates, due to the bottom surface of the screw sleeve 29 and the connecting strip 211 The top surface is fixedly connected, and the connecting strip 211 passes through the fixed plate 210 and is slidably connected, so that the reciprocating groove 28 opened on the surface of the rotating rod 24 will drive the threaded sleeve 29 to move back and forth. When the connecting strip 211 slides back and forth in the fixed plate 210, it will also drive the cleaning brush 215 to slide back and forth, so that the soil covering net body 4 that passes through the connecting box 21 and is rolled up by the rotating shaft 3 can be scraped by the cleaning brush 215, thereby cleaning the soil covering net body 4 and preventing too much dirt on the soil covering net body 4 from affecting the next use.

[0024] Furthermore, as the connecting bar 211 reciprocates with the threaded sleeve 29, the lower protrusion 217 on the top surface of the connecting bar 211 moves along with the connecting bar 211. The back-and-forth movement of the connecting bar 211 will abut against the upper protrusion 219 below the U-shaped frame 218, thereby forcing the connecting bar 211 to vibrate up and down under the action of the spring 216 and the anti-detachment frame 212. The cleaning brush 215 will also be inserted into the mesh of the soil cover net body 4 to clean the soil cover net body 4, improving the cleaning efficiency of the soil cover net body 4, reducing the number of manual cleanings, and making it more convenient to use.

[0025] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
