The protective plate 16 is inclined.

[0034] In this embodiment, by providing the protective plate 16, part of the paint dripping from the surface of the roller brush 2 can be received. By providing the brush 17, the relatively thick paint on the surface of the roller brush 2 can be scraped evenly. The scraped paint enters the triangular material receiving box 15 along the inclination of the protective plate 16, and then is sucked again by the second Y-shaped pipe 12 for secondary use, achieving the purpose of recycling. At the same time, it avoids the problem of paint dripping downward and causing stains on the ground, and also reduces the subsequent cleaning time.

[0035] The outer side of the threaded column 6 is threadedly connected with the mounting frame 18. The bottom of the mounting frame 18 is provided with a mounting block 19. A mounting bolt is penetrated between the mounting frame 18 and the mounting block 19. The bottom of the mounting block 19 is fixedly connected with the connection box 1.

[0036] In this embodiment, by providing the mounting frame 18 and the mounting block 19, the disassembly and assembly between the two are carried out through the mounting bolt. By threadedly fixing and separating the threaded column 6 and the mounting frame 18, it is convenient for the subsequent rapid disassembly of the roller brush 2.

[0037] The opening of the feed metal pipe 5 penetrates into the interior of the discharge cylinder 3, and the spiral docking head 11 is inside the feed metal pipe 5 and is threadedly connected.

[0038] In this embodiment, by setting the spiral docking head 11 and the feed metal pipe 5 to be threadedly connected, it is convenient to disassemble the spiral docking head 11 driving the feed pipe 10 and the feed metal pipe 5, facilitating the subsequent maintenance of the roller brush 2.

[0039] The outer side of the handle 7 is provided with anti-slip patterns. The bottom of the handle 7 is provided with a threaded hole, and the threaded hole is threadedly connected with the telescopic pipe 13.

[0040] In this embodiment, by providing the anti-slip patterns, the staff can hold the handle 7 more stably. By providing the threaded hole, the telescopic pipe 13 is threadedly connected through the threaded hole, facilitating the installation and disassembly of the telescopic pipe.

[0041] The surface of the connection box 1 is fixedly provided with a control module 20. The control module 20 includes a battery box, a battery, and a control switch. The battery is arranged inside the battery box. The battery box is fixedly arranged on the surface of the connection box 1. The control switch is arranged on the surface of the battery box.

[0042] In this embodiment, by providing the battery, the suction pump 8 can be directly powered. By providing the control switch, the start and stop of the suction pump can be directly controlled.

[0043] The implementation principle of an embodiment of the roller brush for construction engineering in this application is as follows: Before use, first thread the telescopic pipe 13 to the bottom of the handle 7, and then place the weight suction block 14 in the external paint bucket. When starting to apply paint, turn on the suction pump 8 through the control switch on the control module 20. After the suction pump 8 generates suction, it sucks through the second Y-shaped pipe 12. With the cooperation of the telescopic pipe 13, the paint is sucked into the suction pump 8, and then discharged into the discharge cylinder 3 through the first Y-shaped pipe 9 and the material delivery pipe 10. The paint penetrates into the roller brush 2 through several discharge holes on the surface of the discharge cylinder 3, achieving the purpose of not needing to dip the brush multiple times. At this time, the staff holds the handle 7 and presses the roller brush 2 against the wall for rolling coating. The handle 7 drives the feed metal pipe 5 and the idle bearing 4 to move, and the discharge cylinder 3 rotates inside under the drive of the idle bearing 4, and the paint on the surface of the roller brush 2 is rolled and smeared on the surface of the building wall; during the process of the roller brush 2 rolling and brushing the surface of the building wall, the protection plate 16 can catch some of the paint dripping from the surface of the roller brush 2. At the same time, the brush 17 on the top of the protection plate 16 can also scrape and level the relatively thick paint on the surface of the roller brush 2, and the scraped paint enters the triangular material receiving box 15 along the protection plate 16 and is then sucked again by the second Y-shaped pipe 12 for secondary use, avoiding the waste of paint, achieving the purpose of recycling, and also avoiding the problem of paint dripping down and causing stains on the ground.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
