However, the present invention can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and will fully convey the scope of the invention to those skilled in the art.

[0023] A waterproof coating coating device for building roofs, such as Figure 1-Figure 7As shown, it includes a frame 1, the upper part of the right side wall of the frame 1 is connected to a handle 2 by bolts, and two movable wheels 3 symmetrically distributed on the front and back sides of the lower part of the frame 1 are installed. A holding bucket 4 is embedded in the upper part of the frame 1, and a stirring paddle 5 is rotatably connected to the bottom of the holding bucket 4. The lower end of the stirring paddle 5 passes through the holding bucket 4 and is fixed with a worm gear 6. The upper part of the frame 1 is rotatably connected to a worm 7 that cooperates with the worm gear 6. A reduction motor 8 is installed on the outer side of the frame 1 through a support. The output end of the reduction motor 8 is connected to the worm gear 7. The reduction motor 8 drives the worm gear 6 through the worm gear 7 to rotate the stirring paddle 5 to apply the waterproof coating in the holding bucket 4. The material is stirred to prevent some substances in the waterproof coating in the storage barrel 4 from settling and affecting the performance of the waterproof coating applied on the subsequent building roof. A slide 9 is provided on the front and rear side walls of the frame 1. A hydraulic rod 10 is fixed to the top of the slide 9. A slider 11 is installed on the bottom end of the hydraulic rod 10 and is slidably connected to the inner side of the slide 9. A tensioning transmission component for power transmission is provided between the frame 1 and the slider 11 on the front side. A painting component for applying waterproof coating on the building roof is provided between the opposite ends of the front and rear sliders 11. A feeding pipe 24 is connected between the painting component and the storage barrel 4, and a valve 25 is provided on the feeding pipe 24.

[0024] The tensioning transmission assembly includes a first pulley 13 rotatably connected to the front slider 11, a second pulley 14 is installed on the output shaft of the reduction motor 8, a transverse groove 15 is opened on the frame 1 on the right side of the slide groove 9, a guide block 16 is slidably connected in the transverse groove 15, a spring 17 is fixed between the guide block 16 and the transverse groove 15, a tensioning wheel 18 is rotatably connected to the guide block 16, and a conveyor belt 19 is sleeved on the outer sides of the first pulley 13, the second pulley 14 and the tensioning wheel 18. During the downward movement of the slider 11, the conveyor belt 19 can always be kept in a taut state through the cooperation of the spring 17, the guide block 16 and the tensioning wheel 18.

[0025] The painting assembly includes a rotating drum 20 fixed to the side wall of the slider 11, the rotating drum 20 is connected to the lower end of the feeding pipe 24, a rotating disk 21 is fixed to the outside of the rotating drum 20, a brush roller 22 is rotatably connected between the outer sides of the front and rear rotating disks 21, and a discharge frame 23 is connected to the rotating drum 20 and fits with the inner side of the brush roller 22.

[0026] The inner side walls of the front and rear sliders 11 are fixed with a connecting frame 26, and a guide frame 27 is fixed between the right ends of the front and rear connecting frames 26. The bottom end of the guide frame 27 is on the same horizontal plane as the bottom end of the brush roller 22, which is convenient for guiding and collecting the cleaned debris. The upper end of the guide frame 27 is higher than the upper end of the brush roller 22, which is convenient for shielding the brush roller 22. The front and rear sides of the right side wall of the guide frame 27 are fixed with support plates 28, and a cleaning roller 29 is rotatably connected between the front and rear support plates 28. The front end of the cleaning roller 29 is fixed with a third pulley 30. A fourth pulley 31 is fixedly connected to the front side wall of a pulley 13, and a flat belt 32 is wound between the third pulley 30 and the fourth pulley 31. The first pulley 13 rotates through the fourth pulley 31 and the flat belt 32 to enable the third pulley 30 to drive the cleaning roller 29 to rotate. The cleaning roller 29 rotates to clean the debris on the roof of the building and sweep the debris into the guide frame 27. By cleaning the debris on the roof of the building, it can be avoided that the waterproof coating is directly applied to the roof of the building through the debris, which affects the adhesion of the waterproof coating to the roof of the building.

[0027] A collecting frame 33 is embedded in the guide frame 27, and the lower part of the collecting frame 33 is rotatably connected to a swinging plate 34. A fixed block 35 is fixed to the side wall of the collecting frame 33, and a sliding rod 36 is slidably connected to the fixed block 35. A stopper 37 is fixed to the upper end of the sliding rod 36, and a tension spring 38 is provided between the fixed block 35 and the lower end of the sliding rod 36. A groove 39 adapted to the stopper 37 is provided on the top of the fixed block 35. The debris in the guide frame 27 moves upward along its inner wall into the collecting frame 33 for collection. By pulling the sliding rod 36, the stopper 37 moves downward into the groove 39, thereby releasing the limit on the swinging plate 34. The swinging plate 34 swings open the collecting frame 33 under the action of gravity, and the debris in the collecting frame 33 is discharged.

[0028] When applying waterproof coating to the roof of a building, first move the frame 1 to the position where the waterproof coating needs to be applied through the moving wheel 3, then add the waterproof coating into the holding barrel 4, and start the hydraulic rod 10 to move the slider 11 downward (during the downward movement of the slider 11, the cooperation of the spring 17, the guide block 16 and the tensioning wheel 18 can keep the conveyor belt 19 in a taut state at all times), the downward movement of the slider 11 drives the brush roller 22 to move downward, and when the brush roller 22 moves downward and contacts the roof of the building, the hydraulic rod 10 is closed and the reduction motor 8 is started and the valve 25 is opened, and the waterproof coating in the holding barrel 4 enters the rotating drum 20 through the feeding pipe 24, and the waterproof coating in the rotating drum 20 enters downward. The brush roller 22 is in contact with the roof of the building. Therefore, in the process of moving the frame 1, the friction between the brush roller 22 and the roof of the building is used to realize rolling. The waterproof coating is applied to the roof of the building by the rolling of the brush roller 22. There is no need for workers to hold the brush roller 22 to pick up the waterproof coating and then apply it. Therefore, the application efficiency of the waterproof coating on the roof of the building can be improved. In the above process, the reduction motor 8 can drive the second pulley 14 and the worm 7 thereon to rotate. The rotation of the worm 7 is driven by the worm gear 6 to rotate the stirring paddle 5 to stir the waterproof coating in the holding barrel 4, so as to prevent the middle of the waterproof coating in the holding barrel 4 from being blocked. The sedimentation of the separated materials affects the performance of the waterproof coating applied on the subsequent building roof. The second pulley 14 rotates through the conveyor belt 19 to rotate the first pulley 13 and the tensioning pulley 18. The first pulley 13 rotates through the fourth pulley 31 and the flat belt 32 to rotate the third pulley 30. The rotation of the third pulley 30 can drive the cleaning roller 29 to rotate to clean the debris on the building roof, and sweep the debris into the guide frame 27, and move upward along the inner wall of the guide frame 27 into the collection frame 33. By cleaning the debris on the building roof, it can be avoided that the waterproof coating is directly applied to the building roof through the debris, which affects the adhesion between the waterproof coating and the building roof. The upper end of the guide frame 27 is higher than the upper end of the brush roller 22. The left side of the guide frame 27 covers the right side position of the brush roller 22, so that the dust raised during the cleaning process of the brush roller 22 can be prevented from falling back into the area after cleaning and applying the waterproof coating. When the waterproof coating of the building roof is completed, the reduction motor 8 and the valve 25 are turned off, and the brush roller 22 is moved upward and reset by the hydraulic rod 10. Then the user pulls the slide bar 36 to move the block 37 downward into the groove 39, releasing the limit on the swing plate 34. The swing plate 34 swings open the collection frame 33 under the action of gravity, and the debris in the collection frame 33 is discharged. Then the swing plate 34 is reset and the slide bar 36 is released. Under the action of the elastic force of the tension spring 38, the block 37 is reset to achieve the limit on the swing plate 34.
