[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] This invention provides a building exterior wall puttying device and method, as shown in Figures 1-9. It includes a vehicle body 1, with a lifting assembly 2, a putty box 3, and a hose box 4 mounted on the top outer wall of the vehicle body 1. The hose in the hose box 4 facilitates the connection length via the spraying assembly 15. A second motor 25 is mounted on the top outer wall of the hose box 4. Rotating rollers 26 are mounted on the inner walls of both sides of the putty box 3 via bearings, and the output end of the second motor 25 is connected to the rotating rollers 26. Stirring rods 27 are mounted on the outer walls of the rotating rollers 26. The second motor 25 drives the rotating rollers 26 to rotate, thereby enabling the rotating rollers 26 to drive the stirring rods 27 to stir the putty in the putty box 3, thus preventing the putty from settling or solidifying. Circular holes are provided on the outer walls of the stirring rods 27 to reduce the resistance between the stirring rods 27 and the putty. A power assembly 5 is located above the lifting assembly 2, and the output end of the power assembly 5 is connected to the lifting assembly 2. Hollow columns 6 are installed on one side wall of the lifting assembly 2. The lifting assembly 2 is driven by the power assembly 5, so that the lifting assembly 2 can drive the hollow columns 6 to rise and fall. This makes it convenient for the device to perform puttying operations on the exterior wall. Springs 7 and connecting columns 8 are respectively installed inside the hollow columns 6. By manually pushing the vehicle body 1, the scraper 13 is brought into contact with the exterior wall. During the contacting process, the scraper 13 applies pressure to the collection box 12 due to the unevenness of the wall surface. This causes the collection box 12 to drive the U-shaped frame 9 to compress into the hollow column 6, thereby adjusting the angle between the fixing plate 10 and the scraper 13 so that the scraper 13 can be completely in contact with the wall surface.

[0036] A U-shaped frame 9 is connected to the end of the connecting column 8 away from the spring 7. A first screw is threaded onto the top outer wall of the U-shaped frame 9. A fixing plate 10 is provided on one side of the U-shaped frame 9. A hollow strip 11 is installed on the outer wall of one side of the fixing plate 10, and the hollow strip 11 is inserted into the U-shaped frame 9. The fixing plate 10 and the U-shaped frame 9 are both fixed by the hollow strip 11 and the first screw. The hollow strip 11 is manually inserted into the inside of the U-shaped frame 9, and then the first screw threaded onto the U-shaped frame 9 is manually rotated, so that one end of the hollow strip 11 is lowered and inserted into the groove on the hollow strip 11, thereby connecting the hollow strip 11 to the U-shaped frame 9. A collection box 12 is installed on the outer wall of the fixing plate 10 away from the hollow strip 11. A spraying assembly 15 is installed on the top outer wall of the putty box 3, and the output end of the spraying assembly 15 is connected to the collection box 12. The assembly is connected to the spraying component 15, which facilitates the spraying of putty onto the exterior wall. A scraper 13 is installed on the inner wall of the collection box 12 via bearings. Limiting plates 14 are installed on one side wall of the collection box 12, and the limiting plates 14 are located on both sides of the scraper 13. The lifting assembly 2 drives the scraper 13 installed on the collection box 12 via bearings to rise and fall. Then, the scraper 13 rises under the action of friction with the wall. The raised scraper 13 is then at a 45-degree angle under the restriction of the limiting plate 14 and scrapes the putty sprayed by the spraying component 15 under the action of the lifting assembly 2.

[0037] Connectors 16 are installed on one outer wall of the fixed plate 10. Through holes are provided on one outer wall of each connector 16. Connecting brackets 17 are inserted into the connectors 16 through these through holes. U-shaped plates 18 are installed at both ends of the connecting brackets 17. A brush roller 19 is mounted on the inner wall of the U-shaped plates 18 via bearings. A telescopic mechanism 20 is installed on one outer wall of the connector 16, with the end of the telescopic mechanism 20 away from the connector 16 connected to the connecting bracket 17. The telescopic mechanism 20 is an electric push rod. The telescopic mechanism 20 drives the connecting bracket 17 to extend and retract under the action of the connectors 16, thereby enabling the connecting bracket 17 to move the U-shaped plates 18 and the brush roller 19 to fit against the wall surface. Then, under the action of friction, the brush roller 19 can rotate. This avoids the waste of putty sprayed by the spraying assembly 15 and also allows the brush roller 19 to rotate. It can evenly spread the putty sprayed on the wall.

[0038] In this embodiment, the lifting assembly 2 includes a mounting frame 201, which is located on the top outer wall of the vehicle body 1. A fixing frame 202 is inserted into the inner side of the mounting frame 201. A second screw 204 is mounted through a bearing on the top outer wall of the fixing frame 202. A power assembly 5 is located on the top outer wall of the fixing frame 202, and the output end of the power assembly 5 is connected to the second screw 204. A plug buckle 205 is mounted on one side outer wall of the mounting frame 201 through a bearing, and the plug buckle 205 is inserted into the opening on the second screw 204. Telescopic positioning rods 203 are respectively installed on one side outer wall of the mounting frame 201. The end of the telescopic positioning rod 203 away from the mounting frame 201 is connected to the fixing frame 202. Mounting posts 206 are provided on the side walls of the telescopic positioning rod 203 and the second screw 204, and the mounting posts 206 are connected to the second screw 204. The hollow column 6 is located on the outer wall of one side of the mounting column 206. The second screw 204, which is mounted on the bearing on the fixing frame 202, is rotated by the power component 5. Under the action of the telescopic positioning rod 203, the second screw 204 can stably drive the mounting column 206 connected to the thread on its side wall to move up and down, so as to facilitate the coating of the spraying component 15 and the scraper 13 on the outer wall.

[0039] In this embodiment, the telescopic positioning rod 203 includes a hollow cylinder 2031, which is located on one side of the outer wall of the mounting frame 201. A connecting rod 2032 is inserted into the inner side of the hollow cylinder 2031, and a third screw 2033 is threaded onto the outer wall of the hollow cylinder 2031. One end of the third screw 2033 extends to the inner side of the hollow cylinder 2031 and is mounted with an arc-shaped plate 2034 via a bearing. The connecting rod 2032 is fixed to the hollow cylinder 2031 via the arc-shaped plate 2034. By manually pulling the connecting rod 2032 inserted into the hollow cylinder 2031 upward, it pushes the fixing frame 202 to rise. Then, by manually rotating the third screw 2033 threaded onto the hollow cylinder 2031, it drives the arc-shaped plate 2034 to fix the connecting rod 2032 with the cooperation of the hollow cylinder 2031, thereby improving the lifting assembly 202. The rising height of the fixed plate 10.

[0040] In this embodiment, the mounting frame 201 has strip grooves on both outer walls, and the fixing frame 202 has T-shaped plates on both outer walls. The fixing frame 202 is connected to the strip grooves and the mounting frame 201 through the T-shaped plates. The fixing frame 202 can rise stably through the strip grooves and T-shaped plates.

[0041] In this embodiment, the power assembly 5 includes a first motor 51, which is located on the top outer wall of the fixing frame 202. The output end of the first motor 51 is connected to a driving bevel gear 52, and a driven bevel gear 53 is installed on the top outer wall of the second screw 204. The driving bevel gear 52 and the driven bevel gear 53 are meshed together. The first motor 51 drives the driving bevel gear 52 to rotate, and the rotating driving bevel gear 52 drives the second screw 204 to rotate through the driven bevel gear 53 meshing with it. This facilitates the lifting and lowering of the mounting column 206 and the application of the spraying assembly 15 and the scraper 13 to the outer wall.

[0042] In this embodiment, a screw box 21 is installed on the top outer wall of the vehicle body 1, and a hose box 4 is located above the screw box 21. A fourth screw 22 is installed inside the screw box 21. A connector plate 23 is installed at one end of the fourth screw 22, and the fourth screw 22 is connected to the second screw 204 via the connector plate 23. A connector groove 24 is installed at the end of the fourth screw 22 away from the connector plate 23, and the connector groove 24 is connected to the connector buckle 205. The fourth screw 22 is manually removed from the screw box 21, and then the connector plate 23 at one end is connected to the opening at the bottom of the second screw 204. Then, the connector groove 24 is connected to the connector buckle 205, thereby ensuring a stable connection between the fourth screw 22 and the second screw 204, which helps to increase the strength of the second screw 204. The length is such that when the mounting bracket 201 and the fixing bracket 202 are adjusted, the second screw 204 is not long enough, which may affect the coating work of the spraying component 15 and the scraper 13.

[0043] In this embodiment, the spraying assembly 15 includes an extraction pump 1501, which is located on the top outer wall of the putty box 3. The input end of the extraction pump 1501 is connected to a connecting pipe 1502, and one end of the connecting pipe 1502 extends to the bottom inner wall of the putty box 3. The output end of the extraction pump 1501 is connected to a delivery hose 1503. A blow pipe 1504 is installed through one side wall of the collection box 12, and the end of the delivery hose 1503 away from the extraction pump 1501 is connected to the blow pipe 1504. The extraction pump 1501 and the connecting pipe 1502 extract the putty from the putty box 3, and then the extracted putty passes through the delivery hose 1503 and is finally sprayed onto the wall from the blow pipe 1504, thereby avoiding the need to scrape putty on the wall.

[0044] A method for applying putty using a building exterior wall puttying device, comprising the following steps:

[0045] S1: First, the vehicle body 1 is manually pushed to get close to the outer wall and make the scraper 13 fit against the outer wall. Then, during the fitting process, the scraper 13 causes the collection box 12 and the U-shaped frame 9 to be compressed into the hollow column 6 due to the unevenness of the wall surface. Then, with the cooperation of the U-shaped frame 9, the first screw and the hollow strip 11, the fixing plate 10 can be tilted and adjusted according to the wall surface, so that the scraper 13 can fit completely against the wall surface.

[0046] S2: The spraying assembly 15 extracts putty from the putty box 3 and sprays it onto the exterior wall. The pump 1501, connected to its input end via a connecting pipe 1502, extracts putty from the putty box 3. The extracted putty then passes through a delivery hose 1503 connected to the output end of the pump 1501 and is finally sprayed onto the wall from the spray nozzle 1504. Simultaneously, the power assembly 5 drives the lifting assembly 2. The first motor 51 drives the active bevel gear 52, which in turn drives the second screw 204 through its meshing driven bevel gear 53. The rotating second screw 204, under the action of the telescopic positioning rod 203, stably moves the threaded mounting post 206 on its side wall up and down. This allows the lifting assembly 2 to move the spring 7 and the fixing plate 10 up and down, enabling the spraying assembly 15 to perform large-area spraying on the exterior wall and also allowing the scraper 13 to... It can follow the spraying component 15 to scrape and smooth the sprayed putty;

[0047] S3: While the lifting component 2 moves, the telescopic mechanism 20 in retraction drives the connecting frame 17 and the U-shaped plate 18 to move, so that the brush roller 19 can fit against the wall. Then, the brush roller 19 in the lifting motion rotates under the action of friction, which can not only avoid the waste of sprayed putty dripping, but also make the putty evenly applied.

[0048] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
