Description

Technical Field

[0001] This utility model relates to the field of wall renovation, specifically a wall paint removal device with walking function for wall renovation. Background Technology

[0002] Wall plastering refers to the removal of the original decorative layer from a wall surface to prepare for the current wall renovation project. Because the putty powder used in the initial stages of construction is often of poor quality and tends to peel off over time, equipment is needed to remove the wall plaster before renovation. A search of application number CN202321595360.1 discloses a wall plastering removal device, which includes a moving platform with two main beams connected to the front of its upper part. A mounting frame is located between the beams and the moving platform. The mounting frame has a nut seat that threads with a lead screw. The mounting frame is slidably assembled with a guide device. A scraper is located on one side of the mounting frame. A water distributor is connected to the upper part of the mounting frame, and one side of the water distributor is connected to and fixed with... The device has multiple nozzles, and a water pump is connected to the left side of the mounting bracket. The water pump's inlet is connected to a water tank via a hose, and its outlet is connected to a distributor via a connecting pipe. A drive motor moves a scraper via a lead screw, allowing the scraper to remove the softened wall plaster. This allows for wall plaster removal during building decoration, saving significant manpower and costs. However, the above description has the following drawbacks in actual use: the device is not convenient for removing plaster from the corners of the wall, limiting its use; and the angle of the scraper cannot be adjusted. Therefore, a more practical wall plaster removal device with a walking function is needed. Utility Model Content

[0031] In practical use: two reciprocating motors 33, together with two mounting bearings 31, drive two reciprocating screws 32 to rotate. The two reciprocating screws 32 drive the reciprocating plate 34 to reciprocate. The reciprocating plate 34, together with the structure inside several buffer sleeves 35, reciprocates. Together with the strip plate 14, it drives the scraper 43 to reciprocate, thereby cleaning the wall plaster. When the scraper 43 is under force, it works with the strip plate 14 to squeeze several buffer rods 37. The several buffer rods 37, together with several buffer sleeves 35, squeeze several buffer springs 36 on the inner wall, thereby buffering the impact force.

[0032] Please see Figure 2 Two moving blocks 13 are set on the surface of two drive screws 15. The bottom of the two drive screws 15 is rotatably connected to the bottom of the inner wall of the two moving grooves 12 through two connecting bearings 16. The top of the two drive screws 15 is fixedly connected to the top of the inner wall of the two moving grooves 12 through two servo motors 17.

[0036] Please see Figure 4 The surfaces of the fixed base 41, the adjusting block 44 and the scraper 43 are all provided with through holes 49, and the inner walls of several through holes 49 are interlocked with the surface of the connecting shaft 42.

[0037] In practical use: the surfaces of the fixed base 41, the adjusting block 44 and the scraper 43 are all connected to the surface of the connecting shaft 42 through the through hole 49, which facilitates the adjustment of the angle of the scraper 43.

[0038] Please see Figure 2 The mobile base 1 has counterweight boxes 18 on both sides of its top.

[0039] The side of the mounting bracket 11 is equipped with a control panel 19, through which the servo motor 17, rotary motor 22 and reciprocating motor 33 are electrically connected to an external power supply.

[0040] In practical use: the two counterweight boxes 18 on the top of the mobile base 1 help to maintain the stability of the overall structure of the device. The control panel 19 is used to control the servo motor 17, the rotary motor 22 and the reciprocating motor 33, so that the device can clean the corners of the wall.

[0041] In use, the two fixing pins 27 are separated from the two limiting rings 28 and the fixing block 25, releasing the auxiliary positioning of the mounting base 24. The rotary motor 22, in conjunction with the rotating shaft 23, drives the mounting base 24 to rotate. The mounting base 24, in conjunction with the reciprocating structure and the strip plate 14, drives the scraper 43 to rotate. After rotating to a 90-degree angle, the two fixing pins 27 are inserted into the two limiting rings 28 and the auxiliary hole 210, limiting the mounting base 24 and the movable base 21 again, thus changing the cleaning direction of the scraper 43, making it easier to clean the wall plaster at the corners. Separate the two sets of positioning pins 47 from the two sets of positioning holes 46 and adjustment holes 48. The scraper 43 drives the two adjustment blocks 44 to rotate on the inner wall of the two fixed seats 41, and drives the fixed plates 45 at both ends of the connecting shaft 42 to rotate on the sides of the two fixed seats 41. When the rotation reaches a suitable angle, insert the two sets of positioning pins 47 into the two sets of corresponding positioning holes 46 and adjustment holes 48, and fix the two fixed plates 45 to the two fixed seats 41 again, thus completing the purpose of adjusting the angle of the scraper 43 and changing the effect of cleaning the wall paint according to the usage environment.
