[0017] The present invention will be further described below with reference to specific embodiments. These specific embodiments are further explanations of the principle of the present invention and are not intended to limit the present invention in any way. Any technology that is the same as or similar to the present invention does not exceed the protection scope of the present invention.

[0018] See Figures 1-2This utility model provides a filter material uniform spreading device, which includes a material conveying pipe 1, a material equalizing screen 2, a spiral spreading rod 3, a tracked mobile base 4, a pusher plate 5, a camera and lighting 6, and a control box. The tracked mobile base 4 is located at the bottom of the spreading device and can travel stably on the filter material despite complex road conditions. The control box is mounted on the tracked mobile base 4 and contains a storage battery 7. The spreading device is electrically driven and powered by the storage battery 7. The camera and lighting 6 are fixedly mounted on the top of the control box and are connected to the storage battery 7 via wiring. The pusher plate 5 is located in front of the tracked mobile base 4, and the spiral spreading rod 3 is located behind it. The top of the control box near the spiral spreading rod 3 is tilted downwards, and the material equalizing screen 2 is located above the tilted part of the control box. The tilt of the control box is consistent with the tilt of the material equalizing screen 2. A spiral spreading rod 3 is installed below the lowest point of the uniform material screen 2. A spreading rod cover with a semi-circular structure and downward opening is installed at the top of the spiral spreading rod 3. The uniform material screen 2, the spiral spreading rod 3, and the battery 7 are connected via wiring. A conveying pipe 1 is installed at the top of the uniform material screen 2. A vibration motor is installed at the bottom of the conveying pipe 1 and on the uniform material screen 2 to ensure more even distribution of filter material into the spiral spreading rod 3. The vibration motor is connected to the battery 7 via wiring. The top of the conveying pipe 1 is connected to the discharge port of the filter material transport equipment. This paving device is controlled remotely.

[0019] When this paving device is used, such as Figure 3 As shown, one end of the conveying pipe 1 is connected to the equalizing screen 2 of the main structure of the paving device. Then, the paving device is hoisted into the confined space of the filter tank using slings. The filter material is conveyed to the equalizing screen 2 through the conveying pipe 1 located above the paving device. The equalizing screen 2 vibrates and spreads the filter material downwards under the drive of the vibrating motor. The rotating spiral spreading rod 3 evenly spreads the filter material spread by the equalizing screen 2 onto the horizontal working surface. The spreading rod cover at the top of the spiral spreading rod 3 prevents the filter material from splashing, so that the equalizing screen 2 and the spiral spreading rod 3 can evenly spread the filter material onto the horizontal working surface to complete the operation, thereby achieving the purpose of high-quality filter material laying. The pusher plate 5 is located in front of the paving device to move and level obstacles for the tracked mobile base 4. The camera and searchlight 6 provide the necessary conditions for operation in the dark and oxygen-free confined space at the bottom of the filter tank. After the paving operation is completed, the paving device is hoisted out of the working surface using slings to complete the filter material laying operation.
