Description

Technical Field

[0001] This utility model relates to the field of building renovation technology, specifically to an exterior wall spraying device. Background Technology

[0003] Patent publication number CN 214462251 U discloses an exterior wall spraying device, including a movable base, a mixing tank, a feeding pump, a feeding hose, a lifting mechanism, and a spray head, all mounted on the movable base. The mixing tank has a top cover, a mixing motor, and a feeding port. The mixing motor is fixedly connected to a mixing shaft that extends into the mixing tank. The mixing tank has a discharge port on its bottom side wall. The feeding end of the feeding pump is connected to the discharge port, and the discharge end of the feeding pump is fixedly connected to the spray head mounted on the lifting mechanism via the feeding hose.

[0004] To address the challenges faced by manual spray painting workers, such as high temperatures and strong winds that severely impact spraying quality and even threaten worker health and safety, existing technologies employ lifting mechanisms to adjust the nozzle assembly, quickly positioning it for spraying on walls of varying heights. While rotating bases and rods allow for horizontal nozzle adjustment, these devices only adjust the horizontal rotation, not the vertical angle. This limits their adaptability to challenging surfaces like sloping walls or curved facades, hindering comprehensive and effective spraying and significantly restricting their application and overall effectiveness.

[0025] Example 1

[0026] like Figure 1-5As shown, this utility model provides an exterior wall spraying device, including a moving mechanism 1, a lifting mechanism 2 on the top surface of the moving mechanism 1, a rotating mechanism 3 on the top surface of the lifting mechanism 2, and an adjusting mechanism 4 on the top surface of the rotating mechanism 3.

The adjusting mounting plate 41 is fixedly installed on the top surface of the turntable 35. Limiting frames 410 are fixedly connected to the front and rear sides of the adjusting mounting plate 41. The two limiting frames 410 are movably connected to the two limiting frames 410 by the movable rod 48. The movable rod 48 is fixedly installed on both sides of the pump body 46.

A lifting screw 27 is fixedly connected to the top end of the first helical gear 26, and the outer wall of the lifting screw 27 is threaded with... A rotating bracket 24 is rotatably connected to the outer wall of the output shaft of the lifting motor 23 connected to the lifting sleeve 28. The rotating bracket 24 is fixedly installed at the bottom of the housing 21. A second helical gear 29 is fixedly connected to the output shaft of the lifting motor 23. A first helical gear 26 is meshed with the outer wall of the second helical gear 29. The bottom end of the first helical gear 26 is fixedly connected to the inner wall of the bearing 25. The bearing 25 is located at the bottom of the housing 21. A lifting screw 27 is fixedly connected to the top of the first helical gear 26. The lifting sleeve 28 is threadedly connected to the outer wall of the lifting screw 27. The rotating mechanism 3 includes a rotating block 31, which is fixedly installed on the top surface of the lifting sleeve 28. A rotating groove 32 is opened on the top surface of the rotating block 31. A rotating motor 34 is fixedly connected to the middle of the top surface of the rotating block 31. A turntable 35 is fixedly connected to the output shaft of the rotating motor 34. Six rotating rods 33 are fixedly connected to the bottom surface of the turntable 35.

This allows the user to adjust the nozzle according to the site conditions. When needed, simply start the lifting motor 23. The output shaft of the lifting motor 23 drives the second helical gear 29 to rotate, which in turn drives the first helical gear 26, which meshes with the second helical gear 29, to rotate. The first helical gear 26 then drives the lifting screw 27 to rotate, causing the lifting sleeve 28, which is threadedly connected to the lifting screw 27, to move upward, thus raising the adjusting mechanism 4 to the required height. Then, start the rotating motor 34. The output shaft of the rotating motor 34 drives the turntable 35 to rotate, thus moving the rotating mechanism 3 to the appropriate horizontal angle. At the same time, the rotating rod 33, which is fixedly connected to the bottom of the turntable 35, rotates on the inner wall of the rotating groove 32, making the overall rotation of the rotating mechanism 3 more stable and allowing the nozzle 47 to move to the required position.

[0031] The working principle of this exterior wall spraying device will be explained in detail below.

[0032] like Figure 1-5 As shown, in use, pushing the push rod 14 causes the device to move to the desired location via the casters 12. Then, the lifting motor 23 is started. The output shaft of the lifting motor 23 drives the second helical gear 29 to rotate, which in turn causes the first helical gear 26, which meshes with the second helical gear 29, to rotate. The first helical gear 26 then drives the lifting screw 27 to rotate, which in turn causes the lifting sleeve 28, which is threadedly connected to the lifting screw 27, to move upward, thereby raising the adjusting mechanism 4 to the desired height. Then, the rotation motor 34 is started. The output shaft of the rotation motor 34 drives the turntable 35 to rotate, thereby moving the rotating mechanism 3 to a suitable angle in the horizontal direction. At the same time, the rotating rod fixedly connected to the bottom surface of the turntable 35... 33 rotates on the inner wall of the rotating trough 32, thereby making the overall rotation of the rotating mechanism 3 more stable, and thus allowing the nozzle 47 to move to the desired position. The adjusting motor 42 is started, and the output shaft of the adjusting motor 42 drives the threaded rod 43 to rotate, thereby causing the slider 44 to move on the threaded rod 43, which in turn causes the slider 44 to drive the pull rod 45 connected to it to move, thereby causing the top of the pull rod 45 to pull the connecting body 49 to move, thereby causing the pump body 46 to rotate inside the limit frame 410 through the connecting body 49, thereby causing the pump body 46 to rotate to the desired position, and then starting the pump body 46. The pump body 46 draws the paint inside the spray box 17 through the connecting pipe 16 and sprays it onto the wall surface through the nozzle 47.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
