[0002] Exterior wall paint is used to coat the exterior walls of buildings. It is a mixture of organic or inorganic materials used to decorate and protect items. Its main function is to resist ultraviolet radiation and protect the wall.

[0003] Currently, most wall painting is done manually by holding a long pole, dipping it in paint, and scraping it across the wall surface. However, this method involves a fixed pole, which makes it inconvenient for the user to scrape the bottom when the pole is too long, and difficult to scrape the top of the wall when the pole is too short. This results in inconvenience for workers, making painting difficult and wasting time.

[0004] Therefore, a coating scraping device for building exterior walls is proposed. Utility Model Content

A rotating cylinder with internal connecting threads is connected to the rotating cavity via a fixed bearing, and a lead screw is connected inside the rotating cylinder. An insertion frame is connected to the bottom end of the outer cylinder, and a motor is installed inside the insertion frame. The output end of the motor passes through the outer cylinder and is connected to the rotating cylinder. The lead screw is connected to the mounting plate via a rotating connection assembly.

[0011] Furthermore, the storage box has an insertion slot with an upper opening on one side of its top.

[0012] Furthermore, the rotating connection assembly includes a connecting top plate disposed at the top of the lead screw, a connecting rotating plate connected to the upper end of the connecting top plate, a connecting rotating seat disposed on the outer side of the mounting plate, and a rotating shaft disposed inside the connecting rotating seat.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model has the following advantages:

[0020] In this invention, the motor is started via the control panel, which causes the rotating cylinder to drive the lead screw to rotate in both directions as needed. During the rotation, the lead screw moves up and down, causing the connecting top plate to move. This makes the length of the handle adjustable, avoiding the situation where the handle length is fixed, which makes it difficult to scrape the top of the wall when the wall height is too high or inconvenient to operate when scraping the bottom of the wall. This makes the scraping operation more convenient for users and can deal with walls of different heights, thus improving its practicality.

[0021] In this invention, by storing sufficient liquid inside the storage tank, the working efficiency is faster during scraping. The handle can be inserted and fixed inside the tank by the insertion slot, which facilitates installation and makes operation simpler. The casters at the bottom of the storage tank make it easy to move, thus improving work efficiency. Attached Figure Description

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0031] Please see Figures 1-6This utility model provides a building exterior wall coating scraping device, including a storage tank 1 for storing the liquid to be scraped, enabling continuous scraping work and improving work efficiency. The storage tank 1 is equipped with casters 2 at its bottom and a pusher 3 on its outer side. The device is moved by pushing with the pusher 3 and using the casters 2, thus making operation more convenient. The storage tank 1 has a discharge port 4 at its bottom and a feed inlet 5 on one side of its top. The discharge port 4 facilitates the discharge of internal liquid, while the feed inlet 5 allows for the replenishment of internal liquid. The storage tank 1 has a pump body 8 installed on its upper end via a pump box 7. The suction end of the pump body 8 is connected to a suction pipe 9 that passes through the bottom of the storage tank 1, so that the pump body 8 generates suction to draw out and discharge the liquid inside. The discharge end of the pump body 8 is connected to a delivery pipe 110 to facilitate the delivery of liquid. The delivery pipe 110 is designed to be stretchable to accommodate rods of different lengths. The top side of the storage tank 1 has an insertion slot 6 with an opening at the bottom, which allows the rod to be inserted into the insertion slot 6 and fixed to the upper end of the storage tank 1. This eliminates the need for manual handling when not in use, improving its practicality.

[0032] A telescopic handle is installed at the top of the storage box 1 to adjust the scraping height. A mounting plate 18 is rotatably connected to the top of the handle. A scraping wheel 117 is rotatably mounted on the inner side of the mounting plate 18 via a fixing plate 116. The scraping wheel 117 is used to scrape the wall. Spray nozzles 19 are installed at the upper and lower ends of the scraping wheel 117 on the inner side of the mounting plate 18 and are connected to the delivery pipe 110. This allows the pump body 8 to spray the adhesive onto the scraping wheel 117 or the wall, avoiding the need to remove the scraping wheel and re-dip it after each scraping, thus improving work efficiency. Scrapers 119 are connected to the upper and lower ends of the inner side of the mounting plate 18 via a fixed telescopic rod 118. A spring 120 is sleeved on the outer side of the fixed telescopic rod 118. The scraper 119 scrapes the wall surface better and more thoroughly, and the spring 120 prevents any impact on the scraping wheel 117.

[0033] The handle includes an outer cylinder 10 on the outside for easy hand operation. A control panel 12 is installed on the outside of the outer cylinder 10, allowing the user to operate it easily and quickly, and facilitating the operation of the electrical components in the device. The outer cylinder 10 has a rotating cavity 112 extending through the upper end. The rotating cavity 112 is connected to a rotating cylinder 113 with internal connecting threads via a fixed bearing 114. A lead screw 13 is connected inside the rotating cylinder 113. An insertion frame 11 is connected to the bottom of the outer cylinder 10, and a motor 111 is installed inside the insertion frame 11. The output end of the motor 111 passes through the outer cylinder 10 and is connected to the rotating cylinder 113. The lead screw 13 is connected to the mounting plate 18 via a rotating connection assembly. This allows the motor 111 to rotate the rotating cylinder 113, which in turn rotates the lead screw 13, causing the mounting plate 18 to move. This allows adjustment of the handle's reach, enabling it to scrape and paint walls of different heights, thus increasing work efficiency and avoiding any impact on the scraping process.

[0034] Preferably, the rotating connection assembly includes a connecting top plate 14 at the top of the lead screw 13, and positioning telescopic rods 115 are installed on both sides of the connecting top plate 14 and connected to the outer cylinder 10. The positioning telescopic rods 115 limit the connection between the connecting top plate 14 and the outer cylinder 10, preventing rotation due to rotational force, and allowing the scraping wheel 117 to move up and down normally, preventing it from rotating to the point of being inconvenient for scraping. A connecting rotating plate 15 is connected to the upper end of the connecting top plate 14, and a connecting rotating seat 16 is provided on the outer side of the mounting plate 18. A rotating shaft 17 is provided inside the connecting rotating seat 16, and a rotating hole is provided inside the connecting rotating plate 15 to rotately connect with the rotating shaft 17. This allows the connecting top plate 14 and the mounting plate 18 to rotate, facilitating the scraping wheel 117 to move and scrape at different heights on the wall, avoiding the situation where it is at a right angle at a high position, which would cause scraping inconvenience.

[0035] Working principle: In use, first connect the pump body 8, control panel 12 and motor 111 to an external power source. Then, move the outer cylinder 10 to move the scraper wheel 117 up and down to scrape the wall. Under the action of the pump body 8 inside the pump box 7, a suction force is generated, which allows the liquid inside the storage tank 1 to be input through the suction pipe 9 and the delivery pipe 110 to the nozzle 19 and sprayed onto the scraper wheel 117 for scraping. Under the control of the control panel 12, the motor 111 at the bottom can drive the rotating cylinder 113 to rotate. Under the action of the positioning telescopic rod 115, the lead screw 13 pulls the connecting top plate 14, which causes the mounting plate 18 to drive the scraper wheel 117 to move up and down. This changes the length of the handle, making it convenient to scrape different parts of the wall, thus completing the work.
