Description

Technical Field

[0001] This utility model relates to the field of spraying technology in engineering construction, specifically a spraying device for construction engineering. Background Technology

[0002] In building construction, wall primer coating needs to be sprayed onto the walls. This requires a spraying machine. The primer is loaded into the machine's hopper, and then pumped through a delivery pipe by the machine's pressure pump to the spray gun, where it is sprayed onto the wall. Currently, when applying the primer using the spray gun, workers need to hold the machine at a specific height to spray, resulting in considerable physical exertion.

[0003] Chinese patent (authorization announcement number: CN 220521882 U, authorization announcement date: 2024.02.23) proposes a spraying device for construction engineering. By setting up a spraying adjustment component, the spray head can be moved in the x and y directions, thereby adjusting the height and left and right position of the spray head according to actual needs, achieving uniform spraying, ensuring spraying quality, and solving the problems of needing workers to hold the spray gun for continuous spraying, increasing manpower and causing uneven spraying.

[0004] When using the above-mentioned device, only the spraying height and left and right position can be adjusted, but the spray head cannot be rotated and the elevation angle cannot be adjusted, which reduces the spraying range. In addition, there are some blind spots when spraying buildings that need to be sprayed manually, but the spray head of the above-mentioned device cannot be disassembled for hand-held spraying, which reduces the practicality of the device. Therefore, we propose a spraying device for construction engineering. Utility Model Content

The angle adjustment assembly allows for adjustment of the spray head's rotation and elevation angles, increasing the spraying range. Furthermore, the spray pipe is mounted on the angle adjustment assembly via a quick-release assembly, allowing for rapid disassembly when hand-held spraying is required. Several grooves and an elastic band are provided on the bottom left side of the spray pipe, allowing it to be securely fastened to the hand, reducing manual labor and improving the device's practicality. Finally, by installing a stirring assembly on the paint tank, the device agitates the paint, preventing it from settling and clumping, which would otherwise affect the spraying process and solve the problems mentioned earlier.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a spraying device for construction engineering, including a base 1, a paint tank 2 and a spraying pump 3 are arranged on the top left side of the base 1, the paint tank 2 has a discharge port 12 and a feed port 10 respectively on the front and rear sides of the top, and a stirring assembly is installed on the paint tank 2. The input end and output end of the spraying pump 3 are respectively fixedly connected to a suction pipe 11 and a conveying pipe 6. The input end of the suction pipe 11 is fixedly connected to the inside of the paint tank 2 through the discharge port 12. The output end of the conveying pipe 6 is fixedly connected to a spraying pipe 18. A spraying head 8 is fixedly installed on the output end of the spraying pipe 18. A baffle 7 is fixedly sleeved on the right side of the spraying pipe 18. A lifting assembly for adjusting the height of the spraying head 8 is installed on the top right side of the base 1. An angle adjustment assembly for adjusting the spraying angle of the spraying head 8 is installed on the lifting assembly. A quick-release assembly is installed between the angle adjustment assembly and the spraying pipe 18.

[0023] When in use, the paint in the paint tank 2 is drawn into the suction pipe 11 by the spray pump 3, then transported to the delivery pipe 6, and finally delivered to the spray pipe 18. It is then sprayed through the spray head 8. During the spraying process, a baffle 7 is set to reduce the amount of paint sprayed onto the device. The paint in the paint tank 2 is stirred by the stirring component to prevent the paint in the paint tank 2 from settling and clumping, which would affect the completion of the spraying work. By installing a lifting component on the top right side of the base 1, and installing an angle adjustment component on the lifting component, the height of the spray head 8 can be adjusted by the lifting component when spraying buildings, and the rotation angle and elevation angle of the spray head 8 can be adjusted by the angle adjustment component, which increases the spraying range of the spray head 8. The spray pipe 18 is installed on the angle adjustment component by a quick-release component. When hand-held spraying is required, the spray pipe 18 can be quickly removed. Several grooves 26 and elastic bands 27 are opened on the bottom left side of the spray pipe 18. The spray pipe 18 is tied to the hand by the elastic bands 27, which reduces the labor intensity of hand-held spraying and improves the practicality of the device.

[0024] The quick-release assembly includes a rotating sleeve 21, a limiting sleeve 19 fixedly sleeved on the spray tube 18, a plurality of limiting grooves 20 opened on the limiting sleeve 19, a stop block 22 fixedly connected to the left side of the inner wall of the rotating sleeve 21, and a plurality of limiting strips 23 fixedly connected to the right side of the inner wall of the rotating sleeve 21. The limiting strips 23 are slidably connected to the limiting grooves 20, and the left side of the limiting sleeve 19 abuts against the right side of the stop block 22.

[0025] When the spray tube 18 needs to be disassembled, rotate the spray tube 18 so that the limiting strip 23 is aligned with the limiting groove 20, and then slide the spray tube 18 to be disassembled from the rotating sleeve 21. When the spray tube 18 needs to be installed, first align the limiting strip 23 with the limiting groove 20, then let the spray tube 18 slide into the rotating sleeve 21 until the left side of the limiting sleeve 19 abuts against the right side of the stop block 22, and then rotate the spray tube 18 to complete the fixing.

[0026] The stirring assembly includes a drive motor 9, which is fixedly installed on the top of the paint tank 2. The output shaft of the drive motor 9 passes through the top of the paint tank 2 and is fixedly connected to a rotating rod 13. Several stirring rods 14 are fixedly connected to the outer surface of the rotating rod 13.

[0027] The drive motor 9 rotates the rotating rod 13, which in turn drives several stirring rods 14 to stir the paint in the paint tank 2.

[0028] The lifting assembly includes an electric push rod 17, which is fixedly installed on the top right side of the base 1. A fixed frame 15 is also fixedly connected to the top right side of the base 1. Sliding plates 16 are slidably connected to the front and rear inner walls of the fixed frame 15. A lifting plate 30 is fixedly connected to the top of the sliding plate 16. The output shaft end of the electric push rod 17 is fixedly connected to the bottom side of the lifting plate 30.

[0029] The lifting plate 30 is raised and lowered by the electric push rod 17, and the sliding plate 16 slides on the inner wall of the fixed frame 15 to complete the limit.

[0030] The angle adjustment assembly includes a third drive motor 32, which is fixedly installed on the top right side of the lifting plate 30. A worm 29 and a worm wheel 31 are also rotatably installed on the top of the lifting plate 30. The front end of the worm 29 is fixedly connected to the output shaft end of the third drive motor 32. The worm wheel 31 meshes with the worm 29. A rotating frame 28 is fixedly connected to the top side of the worm wheel 31. A second drive motor 25 is fixedly installed on the rear side of the rotating frame 28. Connecting rods 24 are fixedly connected to both the front and rear sides of the rotating sleeve 21. Two sets of connecting rods 24 are rotatably connected to the front and rear sides of the rotating frame 28, respectively. One set of connecting rods 24 is fixedly connected to the output shaft end of the second drive motor 25.

[0031] The worm 29 is rotated by the drive motor 32. Since the worm wheel 31 meshes with the worm 29, the worm wheel 31 is rotated, which in turn rotates the rotating frame 28. The connecting rod 24 is rotated by the drive motor 25, which causes the rotating sleeve 21 to rotate on the rotating frame 28.

[0032] Several grooves 26 are provided on the bottom left side of the spray tube 18, and an elastic band 27 is fixedly connected to the bottom left side of the spray tube 18. The spray tube 18 is tied to the hand by the elastic band 27, which reduces the labor intensity of holding the hand.

[0033] A handrail 4 is fixedly installed on the top left side of the base 1, and brakeable casters 5 are installed at the four corners of the bottom of the base 1 to facilitate the movement of the device.

[0034] Working principle: When using this device, the paint in the paint tank 2 is drawn into the suction pipe 11 by the spray pump 3, then transported to the delivery pipe 6, and finally delivered to the spray pipe 18, where it is sprayed through the spray head 8. During the spraying process, a baffle 7 is set to reduce the amount of paint sprayed onto the device. The drive motor 9 rotates the rotating rod 13, which drives several stirring rods 14 to stir the paint in the paint tank 2. Stirring the paint in the paint tank 2 prevents it from settling and clumping, thus affecting the completion of the spraying work.

[0035] The lifting plate 30 is raised and lowered by the electric push rod 17, and the sliding plate 16 slides on the inner wall of the fixed frame 15 to complete the limit, thereby adjusting the height of the spray head 8. The worm gear 29 is rotated by the drive motor 32. Since the worm wheel 31 meshes with the worm gear 29, the worm wheel 31 is rotated, which in turn rotates the rotating frame 28. The connecting rod 24 is rotated by the drive motor 25, so that the rotating sleeve 21 rotates on the rotating frame 28, thereby adjusting the rotation angle and elevation angle of the spray head 8 and increasing the spraying range of the spray head 8.

[0036] When the spray tube 18 needs to be disassembled for hand-held spraying, rotate the spray tube 18 so that the limiting strip 23 is aligned with the limiting groove 20. Then slide the spray tube 18 to disassemble it from the rotating sleeve 21. When the spray tube 18 needs to be installed, first align the limiting strip 23 with the limiting groove 20, then slide the spray tube 18 into the rotating sleeve 21 until the left side of the limiting sleeve 19 abuts against the right side of the stop block 22. Then rotate the spray tube 18 to fix it. Several grooves 26 and elastic bands 27 are provided on the bottom left side of the spray tube 18. The spray tube 18 is tied tightly to the hand by the elastic bands 27, which reduces the labor intensity of hand-held spraying and improves the practicality of the device.
