The function of the drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.

[0025] Please refer to Figure 1-5 , the present utility model provides a technical solution: a dust-proof net laying device for the foundation soil of a construction project, including a moving vehicle 1, a fixing frame 2 is fixedly connected to the surface of the moving vehicle 1, a motor 3 is fixedly connected to the surface of the fixing frame 2, and the output end of the motor 3 penetrates the surface of the fixing frame 2 and is rotatably connected to the inside of the fixing frame 2 to provide power for the operation of the device. A dust-proof net roll 4 is arranged below the fixing frame 2, and a bearing 7 is rotatably connected to one side of the fixing frame 2 away from the motor 3. The inner wall of the bearing 7 is slidably connected to a pushing cylinder 6. The cross-section of the pushing cylinder 6 is in a Chinese character "zhong" shape. Thus, through the setting of the pushing cylinder 6 and the output end of the motor 3, a mounting space is provided for the dust-proof net roll 4.

[0026] A through hole 5 penetrating the surface of the moving vehicle 1 is opened on the surface of the moving vehicle 1 to provide a rising space for the dust-proof net roll 4. At the same time, the height of the moving vehicle 1 from the ground is at least twenty centimeters, so that the dust-proof net roll 4 can be smoothly stuffed under the moving vehicle 1, thereby ensuring the smooth operation of the device.

[0027] A rotating shaft 8 is rotatably connected to the inside of the fixing frame 2. Belt pulleys 12 are fixedly connected to both ends of the rotating shaft 8. A belt pulley 12 is also sleeved on the surface of the motor 3 located inside the fixing frame 2. A belt pulley 12 is also fixedly connected to the surface of the bearing 7 located inside the fixing frame 2. A belt 13 is传动连接 to the surfaces of the four belt pulleys 12. Thus, through the setting of the belt pulleys 12 and the belt 13, the output end of the motor 3 and the rotating shaft 8 can be rotated synchronously, ensuring the smooth operation of the device.

[0028] Furthermore, two winding rollers 9 are fixedly connected to the surface of the rotating shaft 8, and traction ropes 10 are fixedly connected to the surfaces of the two winding rollers 9. The traction ropes 10 pass through the surface of the fixed frame 2 and are slidably connected to the inside of the fixed frame 2. The end of the traction rope 10 away from the winding roller 9 is fixedly connected to a fixing ring 11, and then through the setting of the fixing ring 11, the reels on both sides of the dustproof net roll 4 can be sleeved, so that the device can be connected to the dustproof net roll 4.

[0029] The output end of the motor 3 is internally slidably connected with a limiting block 15 protruding from the surface of the output end of the motor 3. The limiting block 15 is U-shaped, and a limiting groove 16 is provided on the surface of the pulley 12 on the belt 13. The surface of the limiting block 15 is slidably connected to the inner wall of the limiting groove 16. Furthermore, through the setting of the limiting block 15 and the limiting groove 16, when the motor 3 is started, the limiting block 15 can be used to push the inner wall of the limiting groove 16, thereby driving the pulley 12 to rotate, so that the motor 3 can smoothly drive the pulley 12 to rotate, thereby ensuring the smooth operation of the device.

[0030] A spring 17 is fixedly connected to the surface of the limiting block 15, and one end of the spring 17 away from the limiting block 15 is fixedly connected to the inside of the output end of the motor 3 for resetting the limiting block 15. A screw ring 14 is threadedly connected to the surface of the output end of the motor 3, and the screw ring 14 is horn-shaped.

[0031] Specifically, when installing the dust-proof net roll 4, the dust-proof net roll 4 is located at the bottom of the through hole 5, and then the fixing ring 11 is put on the shafts at both ends of the dust-proof net roll 4, and then the motor 3 is started, and then the pulley 12 is driven to rotate through the limiting block 15 and the limiting groove 16, and the rotating shaft 8 is driven to rotate in the fixing frame 2 through the belt 13 and the pulley 12, and then the winding roller 9 is driven to rotate, so that the traction rope 10 is wound, and then the fixing ring 11 and the dust-proof net roll 4 are lifted, so that the drums on both sides of the dust-proof net roll 4 gradually correspond to each other with the output end of the motor 3 and the opposite end of the pushing cylinder 6, and then the staff can The pushing cylinder 6 is pushed, so that the pushing cylinder 6 is inserted into the reel of the dust-proof mesh roll 4, and at the same time, the pushing cylinder 6 pushes the dust-proof mesh roll 4, so that the output end of the motor 3 is inserted into the reel at the other end of the dust-proof mesh roll 4, and the installation of the dust-proof mesh roll 4 is completed. Therefore, the staff only needs to put the fixing ring 11 on the reel at both ends of the dust-proof mesh roll 4 to achieve the installation of the dust-proof mesh roll 4, thereby facilitating the staff to install the dust-proof mesh roll 4, avoiding the situation where the staff needs to lift the dust-proof mesh roll 4 to install the dust-proof mesh roll 4 on the device, facilitating the use of the device, improving the use effect of the device, and having high promotion value and practicality.

[0032] Then the staff can rotate the screw ring 14 to move the screw ring 14 on the output end of the motor 3, so that the inclined surface of the screw ring 14 presses the surface of the limiting block 15, thereby pressing the limiting block 15 into the output end of the motor 3 and compressing the spring 17, so that the limiting block 15 is separated from the limiting groove 16, and then the rotation of the working motor 3 no longer drives the pulley 12 to rotate, and then the staff can continue to start the motor 3, unwind the dustproof net, and lay the dustproof net. Through the setting of the screw ring 14 and the limiting block 15, the limiting block 15 can be separated from the limiting groove 16, thereby avoiding the continuous connection between the output end of the motor 3 and the pulley 12, thereby avoiding the continuous winding and lifting of the dustproof net roll 4 by the traction rope 10, affecting the operation of the device.

[0033] Working principle: Put the fixing ring 11 on the shafts at both ends of the dust-proof net roll 4, then start the motor 3, and drive the rotating shaft 8 to rotate in the fixed frame 2 through the belt 13 and the pulley 12, and then drive the winding roller 9 to rotate, so as to wind up the traction rope 10, and then lift the fixing ring 11 and the dust-proof net roll 4, so that the drums on both sides of the dust-proof net roll 4 gradually correspond to the output end of the motor 3 and the opposite end of the pushing cylinder 6, and then the staff can push the pushing cylinder 6 at this time, so that the pushing cylinder 6 is inserted into the drum of the dust-proof net roll 4, and at the same time, the pushing cylinder 6 pushes the dust-proof net roll 4, so that the output end of the motor 3 is inserted into the drum at the other end of the dust-proof net roll 4, and the installation of the dust-proof net roll 4 is completed.
