[0042] See also Figure 1-8 As shown, a wall spraying machine for building construction, the wall spraying machine for building construction comprises:

[0043] A spray gun 1, wherein an annular fixing frame 2 is fixedly arranged on the outer surface of the spray gun 1;

[0044] A windshield assembly 3, wherein two windshield assemblies 3 are provided, and the two windshield assemblies 3 are respectively provided at two sides of the spray gun 1 and fixedly connected to the annular fixing frame 2;

[0045] A pneumatic component 5, wherein the pneumatic component 5 is arranged at the inner wall of the windshield component 3 and connected to the windshield component 3;

[0046] A flow control component 6, wherein the flow control component 6 is connected to one end of the feed pipe 7, the flow control component 6 is connected to the input end of the annular fixing frame 2, and the flow control component 6 is connected to the pneumatic component 5, and the pneumatic component 5 can automatically make the flow control component 6 close and control the flow in strong winds;

[0047] Through the above-mentioned technical scheme, the wind shield component 3 can effectively shield and protect the sprayed paint, reduce the deviation caused by wind, and control the distance between the nozzle and the wall. Furthermore, in order to avoid the problem of rapid deviation and diffusion of paint caused by sudden strong winds during the spraying process, the present application designs a flow control component 6. Through the coordinated use of the flow control component 6 and the pneumatic component 5, the paint channel can be automatically closed in strong winds, reducing the transportation of paint, thereby reducing the output of paint, thereby protecting the environment and preventing the spread of paint.

[0048] The wind shield assembly 3 includes a fixed support frame 301, a side baffle 302 and a wind deflection baffle 303. One end of the fixed support frame 301 is fixedly connected to both sides of the arc surface of the annular fixed frame 2, and the other end of the fixed support frame 301 is fixedly connected to the side baffle 302. Through the technical solution, the shielding setting of the side baffles 302 on both sides can play an auxiliary shielding and protection function for the spray port of the spray gun 1, thereby avoiding the phenomenon of paint deviation caused by wind blowing;

[0049] The side baffle 302 is provided with an opening, and the opening of the side baffle 302 is rotatably connected to a wind deflection baffle 303. According to the technical solution, when the outdoor wind is strong, the wind will cause the wind deflection baffle 303 to deflect;

[0050] A spacing control component 4 is fixedly arranged at one end of the side baffle 302, and the spacing control component 4 includes a rectangular fixed seat 401, a rectangular moving rod 402, a connecting frame 403, a roller 404 and a locking bolt 405. The rectangular fixed seat 401 is fixedly arranged at one end of the side baffle 302, and an inner cavity is arranged inside the rectangular fixed seat 401, and the rectangular moving rod 402 is slidably connected in the inner cavity of the rectangular fixed seat 401, and a connecting frame 403 is fixedly connected at one end of the rectangular moving rod 402, and a roller 404 is rotatably connected on the connecting frame 403;

[0051] The side wall of the rectangular fixing seat 401 is threadedly connected with a locking bolt 405. Through the technical solution, the spacing control component 4 can play the function of controlling the spacing between the spray gun 1 and the wall. When the spray gun 1 is spraying, the roller 404 can be brought into contact with the wall and rolled on the wall by the roller 404, so that the spray gun 1 can be driven to move and spray the wall. Due to the limiting effect of the spacing control component 4, the spacing between the spray gun 1 and the wall can be controlled. When it is necessary to adjust the spacing between the spray gun 1 and the wall, the rectangular moving rod 402 can be moved by manually loosening the locking bolt 405, thereby adjusting the position of the rectangular moving rod 402, and then adjusting the position of the roller 404. After adjustment, the locking bolt 405 is re-tightened to lock and fix the rectangular moving rod 402.

[0052] The pneumatic assembly 5 includes a fixed tripod 501, a fixed cylinder 502, a movable piston 503, a movable rod 504, a fixed circular plate 505, a return spring 506, a first connecting frame 507, a connecting arm 508 and a connecting hose 510. The fixed tripod 501 is fixedly arranged on the side wall of the side baffle 302. The fixed cylinder 502 is fixedly connected to the upper surface of the fixed tripod 501. The movable piston 503 is slidably connected in the inner cavity of the fixed cylinder 502. One end of the movable rod 504 is fixedly connected to the bottom surface of the movable piston 503. The other end of the movable rod 504 penetrates the bottom wall of the fixed cylinder 502 and the fixed tripod 501 and extends to the outside of the wall of the fixed tripod 501.

[0053] A fixed circular plate 505 is fixedly connected to the bottom end of the moving rod 504, one end of a return spring 506 is fixedly connected to the upper surface of the fixed circular plate 505, and the other end of the return spring 506 is fixedly connected to the bottom surface of the fixed tripod 501;

[0054] A first connecting frame 507 is fixedly connected to the bottom surface of the fixed circular plate 505, one end of a connecting arm 508 is rotatably connected to the first connecting frame 507, the other end of the connecting arm 508 is rotatably connected to a second connecting frame 509, the second connecting frame 509 is fixedly connected to the side wall of the wind deflector 303, and a connecting hose 510 is fixedly connected to the upper end of the inner cavity of the fixed cylinder 502;

[0055] The flow control assembly 6 includes a fixed sleeve 601, a fixed support plate 602, an expansion airbag 603, a connecting pipe 604 and a rubber ring 605. One end of the fixed sleeve 601 is fixedly connected to the input end of the spray gun 1, and the other end of the fixed sleeve 601 is fixedly connected to one end of the feed pipe 7. According to the technical solution, the paint is transported to the inner cavity of the fixed sleeve 601 through the feed pipe 7, and then input to the spray gun 1 through the fixed sleeve 601, and the paint is sprayed out through the spray gun 1;

[0056] A fixed support plate 602 is fixedly connected to the side wall of the inner cavity of the fixed sleeve 601, and an expansion airbag 603 is fixedly connected to the side wall of the fixed support plate 602. A rubber ring 605 is fixedly connected to the arc-shaped inner wall of the fixed sleeve 601. A connecting pipe 604 is fixedly connected to the inner cavity of the expansion airbag 603. The connecting pipe 604 is fixedly connected to the connecting hose 510. According to the technical solution, when spraying construction is carried out outdoors and strong winds suddenly appear, the wind deflector 303 will be deflected due to the wind, so that the inward deflection of the wind deflector 303 will drive the connecting arm 508 to rotate angularly, so that the angular rotation of the connecting arm 508 can push the first connecting frame 507 to move upward, thereby pushing the moving rod 504 to move upward. Since the upward movement of the moving rod 504 can push the moving piston 503 to move upward, the upward movement of the moving piston 503 can make the gas in the inner cavity of the fixed cylinder 502 pass through the connecting rod 504. The connecting hose 510 is pushed into the inner cavity of the expansion airbag 603, so that the expansion airbag 603 is expanded. The expansion of the expansion airbag 603 can reduce the gap between the expansion airbag 603 and the rubber ring 605. As the expansion airbag 603 gradually expands, the expansion airbag 603 and the rubber ring 605 are fitted together, so that the inner cavity of the fixed sleeve 601 is closed, thereby closing the conveying of the paint, and then stopping the supply of the paint, thereby avoiding the deviation of the paint due to wind during spraying. From the above description, it can be seen that the present application uses the pneumatic component 5 and the flow control component 6 in combination, so that when a strong wind suddenly occurs outdoors, the conveying of the paint can be automatically closed, thereby avoiding the deviation of the paint caused by the spraying in strong winds. When the wind force is small, the wind force is not enough to push the wind deflector 303 to deflect, so that the spray gun 1 can spray normally, and the wind shielding component 3 plays a role of shielding and preventing wind.

[0057] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
