[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Refer toFigure 1-6 An outdoor spraying device for building construction, comprising a material storage barrel 2 and a spray gun 7. A cleaning tank 3 and a driving motor 8 are respectively installed on the material storage barrel 2. A main pipe 4 is arranged outside the cleaning tank 3. A cleaning pipe 19 and a number of branch pipes 15 are respectively connected to the main pipe 4. The other ends of the branch pipes 15 are connected to the material storage barrel 2 in a penetrating manner. The other end of the cleaning pipe 19 is connected to the cleaning tank 3. A first cavity 10, a second cavity 11 and a third cavity 12 are arranged in the material storage barrel 2. A first partition plate 13 and a second partition plate 27 are arranged between the first cavity 10, the second cavity 11 and the third cavity 12. A first rotating shaft 9 and a second rotating shaft 20 are respectively installed above and below the first partition plate 13. A third rotating shaft 21 is arranged below the second partition plate 27. A first stirring blade 22 and a second stirring blade 25 are respectively installed on the first rotating shaft 9, the second rotating shaft 20 and the third rotating shaft 21.

[0029] By adopting the above technical solution, when performing spraying operations of multiple colors according to the requirements of the building construction design drawings, the operator operates the switch controller 5 on the spray gun 7, opens the solenoid valve 14 on the branch pipe 15 outside the first cavity 10, and starts the suction pump 6 to work, so that the paint in the first cavity 10 enters the branch pipe 15 through the suction pipe 16, and is sprayed out from the spray gun 7 through the main pipe 4 to perform spraying operations on the building exterior wall. Then, the solenoid valve 14 on the branch pipe 15 of the first cavity 10 is closed, and at the same time the suction pump 6 is paused. The solenoid valve 14 of the cleaning pipe 19 is opened, and the suction pump 6 is started to clean the pipeline and the spray gun 7 with cleaning water. Then the suction pump 6 is paused and the solenoid valve 14 of the cleaning pipe 19 is closed. The solenoid valve 14 on the branch pipe 15 of the second cavity 11 or the third cavity 12 is opened, and the suction pump 6 is started to perform spraying operations of the second color. By performing a cleaning action every time the color is changed, it is ensured that no color mixing occurs at the initial stage of each color-changing spraying, avoiding waste of a large amount of spray paint due to covering color mixing. At the same time, this device only requires one person to complete the convenient color-changing work of spraying multiple colors on the building construction exterior wall, which is convenient to use.

[0030] As Figure 1 shown in Figure 2 the figure, solenoid valves 14 are installed on both the main pipe 4 and a number of branch pipes 15. The other end of the main pipe 4 is installed with a suction pump 6. The discharge end of the suction pump 6 is connected to the spray gun 7 through a connecting pipe. A switch controller 5 is installed on the spray gun 7.

[0031] By adopting the above technical solution, the switch controller 5 is electrically connected to the solenoid valve 14 and the suction pump 6. Through the switches corresponding to the components on the switch controller 5, the opening and closing actions of the array of solenoid valves 14 and the suction pump 6 can be independently controlled, thus facilitating the smooth progress of the spraying work of different colors. Moreover, by closing the solenoid valve 14 between the main pipe 4 and the suction pump 6 and opening the solenoid valves 14 on each branch pipe 15 and the cleaning pipe 19, the cleaning liquid flows from the main pipe 4 into each branch pipe 15 and enters the first cavity 10, the second cavity 11, and the third cavity 12, facilitating the cleaning of the storage bucket 2. After the cleaning action is completed, the suction pump 6 and the solenoid valve 14 connected to the main pipe 4 are opened to spray out the cleaning water. Repeat the above operations until the sprayed water is no longer turbid, and the cleaning work of the storage bucket 2 is completed.

[0032] As Figure 2 , Figure 3 shown in Figure 6 Figure, a bearing 24 is embedded in the middle of the first partition 13. A suction groove 26 is provided outside the bearing 24. One side of the suction groove 26 is connected to a suction pipe 16, and the other end of the suction pipe 16 is connected to the branch pipe 15. The internal structure of the first partition 13 is the same as that of the second partition 27.

[0033] By adopting the above technical solution, through the arrangement of the first partition 13 and the second partition 27, the storage bucket 2 is divided into multiple containers that can store different color spraying materials, enabling the spraying operation of the exterior walls of building construction in multiple colors, and having high practicability.

[0034] As Figure 2 shown in Figure 3 Figure, the outer walls of the relative ends of the first rotating shaft 9 and the second rotating shaft 20 are both connected to the inner wall of the inner ring of the bearing 24. The first rotating shaft 9 and the second rotating shaft 20 are rotationally connected to the first partition 13 through the bearing 24. The other end of the first rotating shaft 9 is connected to the output end of the driving motor 8.

[0035] By adopting the above technical solution, after the first rotating shaft 9 is rotated by the driving motor 8, the second rotating shaft 20 and the third rotating shaft 21 connected to the bottom bearing 24 are driven to rotate synchronously, and the spraying materials of various colors in the storage bucket 2 are evenly mixed. Moreover, through the arrangement of the suction groove 26, the spraying materials in the cavity are gathered in the suction groove 26, facilitating the suction of the spraying materials by the suction pipe 16 and avoiding the waste of a large amount of spraying materials caused by the adhesion of the spraying materials to the inner wall of the cavity.

[0036] As Figure 3 shown in

[0037] By adopting the above technical solution, the auxiliary stirring blades 17 of the second rotating shaft 20 can mix the spraying material at the discharge port 18 below the storage barrel 2, making the spraying material uniform, and thus making the spraying smooth.

[0038] As Figure 2 shown in Figure 3 Figure, sealing members 23 are provided at the joints of the first rotating shaft 9 and the bearings 24, and the sealing members 23 are in a conical structure.

[0039] By adopting the above technical solution, due to the conical sealing members 23, the spraying material on the first rotating shaft 9, the second rotating shaft 20 and the third rotating shaft 21 can flow along the conical sealing members 23 into the suction groove 26, so that the spraying material in the storage barrel 2 can be maximally used during the spraying process, which has high practicability.

[0040] As Figure 3 shown in Figure 4 Figure, two groups of first scraping plates 2201 are distributed at the end of the first stirring blade 22.

[0041] By adopting the above technical solution, two groups of first stirring blades 22 are arranged in the first cavity 10, and one group of first stirring blades 22 and second stirring blades 25 are respectively arranged in the second cavity 11 and the third cavity 12. When the spraying material remaining in the cavity is too little, through this combination, the spraying material adhered to the inner wall of the storage barrel 2 can be scraped, and due to the inclination directions of the first stirring blade 22 and the second stirring blade 25, the scraped spraying material can smoothly flow into the suction groove 26 for the suction pipe 16 to suck, avoiding waste of the spraying material adhered to the inner wall of the storage barrel 2.

[0042] As Figure 3 shown in Figure 5 Figure, a second scraping plate 2501 is arranged at the end of the second stirring blade 25, and the second scraping plate 2501 is triangular.

[0043] By adopting the above technical solution, the second scraping plate 2501 can cooperate with the first scraping plate 2201 to scrape the remaining material inside the storage barrel 2.

[0044] As Figure 1 shown in Figure 2 Figure, the storage barrel 2 is installed on the mobile vehicle frame 1. An outlet 18 and a feed inlet are respectively arranged on the storage barrel 2. The outlet 18 is connected to the main pipe 4 through a branch pipe 15, and the number of the outlets 18 is equal to the number of the branch pipes 15. The mobile vehicle frame 1 facilitates the device to move to the construction area for spraying work. The feed inlet is not marked in the drawing, and the structure of the feed inlet is not introduced in the present invention. Since it does not involve the design key points and improvement directions of the present invention, it is the same as the prior art or can adopt the prior art to be implemented, and will not be elaborated here.

[0045] Working principle: When performing the spraying operation in building construction, first, according to the on-site construction conditions, pour the spraying materials of different colors required into the first cavity 10, the second cavity 11, and the third cavity 12 from the feed ports on the storage barrel 2. Then, drive the first stirring blades 22 and the second stirring blades 25 on the first rotating shaft 9, the second rotating shaft 20, and the third rotating shaft 21 by the driving motor 8 to perform the mixing operation in each cavity. Next, according to the design requirements of the building construction, operate the switch controller 5 on the spray gun 7 to open the solenoid valve 14 on the corresponding color cavity branch pipe 15 in the corresponding storage barrel 2 to perform the spraying operation of one color. Again, when it is necessary to perform the spraying operation of the second color, the solenoid valve 14 installed on the branch pipe 15 of the corresponding opened first cavity 10 or the second cavity 11 or the third cavity 12 can be operated to close, and the solenoid valve 14 on the cleaning pipe 19 is opened, so that the clear water is pumped by the suction pump 6, and the clear water enters the main pipe 4 and the pipe connected to the spray gun 7 and sprays out from the nozzle of the spray gun 7 to complete a set of cleaning operations. Finally, close the solenoid valve 14 on the cleaning pipe 19, open the solenoid valve 14 on the other group of color-corresponding branch pipes 15, and through the operation of the suction pump 6, perform the spraying operation of another color of paint. Repeat the above operations multiple times until the building construction spraying operation of the design drawing is completed. Through the above cross operations of color changing and flushing, one person can complete the construction color-changing spraying operation without additionally arranging a person to wait at the storage barrel 2 to perform the position shifting operation of the connecting pipe of the spray gun 7, which is convenient to use. At the same time, when changing colors, the connecting pipe of the spray gun 7 does not store the previous color, avoiding the need to waste more paint to cover the mixed color area. Through this structural design, when performing multi-color spraying operations, the labor cost is greatly saved, and the color-changing efficiency of multi-color spraying operations is also improved.

[0046] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacements or changes, and should be covered within the protection scope of the present utility model.
