If manual spraying operation is adopted, the spraying operation range is limited, there are problems such as low construction efficiency, high labor intensity, and harm to personnel health during spraying operation. In addition, due to the influence of personnel construction experience in manual spraying, the thickness of the waterproof coating on the operation surface is uneven, resulting in large quality fluctuations and unable to guarantee the construction quality. Content of the Utility Model

[0021] As Figure 1 and Figure 2As shown in the figure, the utility model includes a roller 1 and a hollow rotating shaft 2 that passes through the roller 1 and is arranged at the central position of the roller 1. One end of the hollow rotating shaft 2 is an open structure. The hollow rotating shaft 2 is connected to the roller 1 through multiple sets of spoke mechanisms. The spoke mechanism includes a plurality of hollow spokes 7 arranged on the periphery of the hollow rotating shaft 2. One end of the hollow spoke 7 is communicated with the hollow rotating shaft 2, and the other end of the hollow spoke 7 passes through the roller 1 and is communicated with a material storage and coating layer 8 outside the roller 1. The open end of the hollow rotating shaft 2 is communicated with a fixed feed pipe 4 through a sealed rotary joint 3. A connecting flange 6 connected to the waterproof coating delivery pump pipe is installed at the outer end of the fixed feed pipe 4. Centripetal bearings 9 are sleeved on both ends of the hollow rotating shaft 2 outside the roller 1 respectively. The two centripetal bearings 9 are connected through a U-shaped traction mechanism 10. A traction hook 11 connected to a tractor is arranged on the traction mechanism 10.

[0022] It should be noted that through the design of the hollow shaft and the hollow spokes, the waterproof coating is introduced into the device and evenly flows into the material storage and coating layer by rotation, completing the automatic feeding of the coating from inside the device. By connecting with the power mechanism, the device completes the roller coating operation on the construction surface while rolling forward, realizing the automatic continuous operation of the coating construction operation, reducing the participation of personnel in the construction process, ensuring the health and safety of construction workers while reducing the labor intensity, completing the roller coating while walking, having the characteristics of automatic feeding and continuous walking, capable of continuous construction operation, with a large roller coating area and high construction efficiency; equipped with a material blocking and scraping mechanism, the coating construction thickness can be adjusted by scraping according to requirements during actual construction, and it is automatically scraped after roller coating, ensuring the uniform thickness of the coating on the construction surface and improving the construction quality; the material of the discharging layer of the material storage and coating layer 8 is suction flannelette or sponge and other materials, and the surface layer is a smooth fluff material.

[0023] In this embodiment, a plurality of hollow spokes 7 in the spoke mechanism are evenly arranged at equal intervals on the periphery of the hollow rotating shaft 2.

[0024] In this embodiment, a valve 5 is installed on the fixed feed pipe 4.

[0025] In this embodiment, a material blocking plate 12 arranged outside the material storage and coating layer 8 is also connected between the two centripetal bearings 9. A scraping rubber strip 14 is arranged at one end of the material blocking plate 12 close to the coating surface. The scraping rubber strip 14 is connected to the material blocking plate 12 through an adjusting bolt 13.

[0026] During the construction operation of this utility model, the waterproof coating delivery pump pipe is communicated with the fixed feed pipe 4 through the connecting flange 6, and the valve 5 is opened to enable the waterproof coating to flow along the fixed feed pipe 4 and enter the inside of the hollow rotating shaft 2 through the sealed rotary joint 3.

[0027] Next, connect the towing hook 11 to power mechanisms such as trucks and winches. Start the power mechanism to move forward. The traction mechanism transmits the forward pulling force to the connected radial bearing. The outer ring of the radial bearing 9 is fixed and does not rotate, and the inner ring rotates in a circular motion after being stressed. Since the inner side of the radial bearing 9 is fixed to the hollow rotating shaft 2, the hollow rotating shaft 2 is driven to rotate 360° around the sealed rotary joint 3 and inside it. One end of the sealed rotary joint 3 is connected to the rotating and movable hollow rotating shaft 2, and the other end is fixedly connected to the fixed feed pipe 4. While one end rotates and the other end remains stationary, the two sections of pipes can be fully sealed, preventing the waterproof coating from overflowing, and enabling the hollow rotating shaft 2 to rotate flexibly around it without falling off. The rotating hollow rotating shaft 2 drives multiple groups of hollow spokes 7 evenly fixed around it to rotate.

[0028] Since the other end of the hollow spoke 7 is fixedly connected and communicated with the material storage and coating layer 8, the material storage and coating layer 8 is driven to rotate together, and finally the entire device is driven to roll forward under the drive of the hollow rotating shaft.

[0029] While the waterproof coating flows into and fills the inside of the hollow rotating shaft 2, and with the rolling and rotation of the device, the waterproof coating will evenly flow into the inside of the material storage and coating layer 8 through the hollow spokes 7.

[0030] The design of the hollow spokes can, on the one hand, serve as a flow-through channel for the waterproof coating, and on the other hand, prevent the deformation of the material storage and coating layer 8 on the outer ring of the roller coating device, increase its strength, support its continuous rotation. Since the lining material of the material storage and coating layer 8 is made of material such as absorbent flannelette or sponge, it can fully absorb and store the flowing-in waterproof coating, ensure that the coating is full during brushing, and complete the roller coating of the working surface through the smooth fluff on the surface layer.

[0031] During operation, according to the requirements of the brushing thickness of the waterproof coating, adjust the opening degree of the valve 5 in real time to control the flow rate of the coating entering the roller coating device; and adjust the adjusting bolt 13 at the bottom of the baffle 12 to adjust the ground clearance of the scraping rubber strip 14, and perform corrective scraping on the thickness after brushing to make it uniform in thickness, meet the requirements of the construction brushing thickness, and improve the construction quality.

[0032] In addition, in order to prevent the coating from splashing during roller coating and affecting the construction quality of the already constructed area, a baffle 12 is also connected to the outer ring of the radial bearing 9, which is arranged outside the material storage and coating layer 8. During construction operations, while the device rolls forward, continuous feeding of the waterproof coating is achieved, and the roller coating of the working surface is completed by relying on the smooth fluff on the surface of the rotating material storage and coating layer 8. The thickness control of the constructed surface after roller coating is achieved by controlling the height of the scraping rubber strip 14 at the bottom of the device. Through continuous walking, automatic feeding, and automatic scraping, the automatic operation of the device is realized, improving the construction efficiency and construction quality. Thus, the automatic roller coating operation of the construction surface is completed.

[0033] The above are only the preferred embodiments of the present utility model, and do not impose any limitations on the present utility model. Any simple modifications, changes, and equivalent structural changes made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
