[0053] See Figures 1-7 This utility model provides a technical solution:

[0054] A wall plaster removal device includes: a support frame 1, a housing 2, a wall breaking component 3, a scraper component 4, and a spraying component 5;

[0055] The housing 2 is connected above the support frame 1, and the scraper assembly 4 is movably connected to the outside of the housing 2. The wall surface is scraped off by the reciprocating movement of the scraper assembly 4. In order to facilitate the scraping of the wall surface, the scraper 44 protrudes from one side of the support frame 1 and the housing 2; in this way, the head of the scraper 44 protrudes, which makes it easy to scrape off the wall surface.

[0056] The wall-breaking component 3 is rotatably connected to the outside of the housing. The wall-breaking component 3 is telescopically connected to the housing. Before the wall plaster removal work, the wall-breaking component 3 needs to extend to the working surface and reach in front of the scraper component 4. Then, the wall-breaking component 3 breaks the flat wall surface by rotating. After the work is completed, the wall-breaking component 3 retracts back behind the scraper component 4, leaving working space for the scraper component 4.

[0057] The spraying assembly 5 is located inside the housing 2, and the nozzle 51 of the spraying assembly 5 is located in the core of the wall-breaking assembly 3. The spraying assembly 5 is used to spray putty solvent. When the wall-breaking assembly 3 needs to reach the work surface, since the spraying assembly is located in the core of the wall-breaking assembly 3, the spraying assembly also reaches the work surface. At this time, the spraying assembly 5 sprays putty solvent onto the wall. The composition of the putty solvent is shown in Table 1.

[0058] Table 1. Putty Solvent Composition

[0059]

[0060] To facilitate the scraper assembly 4 in removing material from the wall, the scraper assembly 4 also includes: a first motor 41, a first gear shaft 42, and a rack 43. The first motor 41 is fixedly connected to the housing 2. The output end of the first motor 41 is connected to one end of the first gear shaft 42. The gear at the other end of the first gear shaft 42 meshes with the first rack 43, is slidably connected to the housing 2, and is fixedly connected to the first rack. When the first motor 41 rotates, it drives the first gear shaft 42 to rotate. The gear on the first gear shaft 42 drives the first rack 43 to move linearly, causing the scraper 44 to move linearly and scrape against the wall surface.

[0061] Preferably, the number of first racks 43 is 2, and the two first racks 43 are arranged opposite each other. Both first racks 43 are engaged with the gears of the first gear shaft 42. When the first gear shaft 42 rotates, the two shovels 44 move towards each other or away from each other.

[0062] The blending assembly 3 includes a blending turntable 31, a ball screw spline 32, a second motor 33, and a third motor 34. The housing 2 supports the outer ring 327 of the ball screw spline 32. The second motor 33 and the third motor 34 are fixedly connected to the housing 2. The output end of the second motor 34 is connected to the spline nut 325 of the ball screw spline 32 via gears, and the output end of the third motor 34 is connected to the screw nut 326 of the ball screw spline 32 via gears. The blending turntable 31 is fixedly connected to one end of the screw 321 of the ball screw spline 32. When the third motor 34 rotates and the second motor 33 stops working, the third motor 34 drives the screw nut 326 to rotate, causing the screw 321 to move linearly. When the third motor 34 stops working and the second motor 33 rotates, the spline nut 325 engages with the spline groove 322 on the screw 321, causing the screw to move helically. When both the third motor 34 and the second motor 33 rotate, the screw 321 rotates. In this application, the lead screw 321 only needs linear and rotary motion, and does not need to perform helical motion. That is, when the cell wall breaking component 3 is working, the third motor 34 is started first to make the lead screw 321 perform linear motion. When the cell wall breaking turntable 31 reaches the working surface, both the third motor 34 and the second motor 33 are started. The cell wall breaking turntable 31 performs rotary motion under the drive of the lead screw 321, breaking the cell wall.

[0063] The blending turntable 31 includes a disc 311, a blending nail 312, a spring 313, and a pressure sensor 314. One end of the disc 311 is fixedly connected to a lead screw 321, and the other end of the disc has a hole in which the blending nail 312 is slidably mounted. The pressure sensor 314 is located at the bottom of the hole, and the spring 313 is positioned between the pressure sensor 314 and the blending nail 312. When the third motor 34 starts, after the blending turntable 31 reaches the working surface, the blending nail 312 contacts the wall. Under the action of the wall, the blending turntable 31 continues its linear motion, causing the blending nail 312 to compress the spring 313. The spring force of the spring 313 acts on the pressure sensor 314. When the spring force reaches a set value, the third motor 34 stops and sprays putty solvent onto the wall. After spraying, both the third motor 34 and the second motor 33 start, and the blending turntable 31 begins to rotate. This allows for better control of the force of the blending turntable.

[0064] The spraying assembly 5 also includes a pump 52 and a pipe 53. The pump 52 is fixed inside the housing 2. The inlet of the pump 52 is connected to a solvent. The container holding the solvent can be placed on the ground or on the support frame 1. The inlet of the pump 52 is connected to the putty solvent through a pipe. The outlet of the pump 52 is connected to the pipe 53, and the other end of the pipe 53 is connected to the nozzle 51.

[0065] The nozzle 51 is fixed at the end of the disc 311 away from the lead screw 321. The disc 311 and the lead screw 321 are hollow. The pipe 53 is located in the core of the disc 311 and the lead screw 321, so that the nozzle 51 can move with the wall-breaking turntable 31.

[0066] The spraying assembly 5 also includes a heater, which is a spiral ceramic heater placed in the pipe to heat the softener, making it easier for the wall coating to adhere.

[0067] The housing 2 is hinged to the support frame 1, and the housing 2 can rotate around the hinge point. This allows for the removal of the wall plaster from the ceiling. The rotated plaster removal device... Figure 7 As shown.

[0068] To prevent wall plaster from falling into the housing 2 during ceiling removal, the wall plaster removal device also includes a door assembly 6. The door assembly 6 comprises a door 61, a fourth motor 62, a second gear shaft 63, and a second rack 64 fixed to the door. The door 61 is slidably connected to the rear of the scraper assembly 4. The fourth motor 62 is fixedly connected to the housing 2, and its output end is connected to the second gear shaft 63. The gear of the second gear shaft 63 meshes with the second rack 64. Before operation, the door 61 closes the housing, leaving only the scraper assembly 4 outside. When the product needs to break down the wall, the fourth motor 62 starts, rotating the second gear shaft 63, which in turn moves the second rack 64 linearly. Since the second rack 64 is fixed to the door 61, the door 61 moves towards one side of the housing, exposing the wall-breaking turntable 31. After the wall-breaking turntable 31 finishes its operation, the fourth motor 62 rotates in the opposite direction, and the door 61 closes.

[0069] To facilitate the removal of wall plaster using a mobile phone, a collector 7 is also included. The collector 7 is fixed below the housing 2, and the opening of the collector 7 faces the shovel assembly 4.

[0070] The workflow disclosed in this application is as follows:

[0071] Move the device to the location where the wall plaster needs to be removed, then adjust the telescopic device 11 to adjust the scraper assembly 4 to a suitable height, then adjust the telescopic rod 12 so that the telescopic rod touches the ground, then start the fourth motor and open the hatch 61. Next, start the third motor 34, which drives the lead screw nut 326 to rotate, causing the lead screw 321 to move linearly, moving the wall-breaking turntable 31 to the position on the wall. When the wall-breaking nail 312 contacts the wall, the wall-breaking turntable 31 continues to move, compressing the spring 313. The spring force of the spring 313 acts on the pressure sensor 314. When the spring force reaches the set value, the third motor 34 stops and sprays putty solvent onto the wall. After spraying, both the third motor 34 and the second motor 33 start, and the wall-breaking turntable 31 begins to rotate, breaking the smooth wall surface. After the wall-breaking turntable 31 finishes its work, both the third motor 34 and the second motor 33 stop working. At this time, the wall-breaking turntable 31 stops rotating, and then the third motor 34 reverses to retract the wall-breaking turntable 31. The fourth motor is started in reverse, the hatch 61 is closed, the first motor 41 is turned on, and the scraper 44 moves in a straight line to scrape off the wall plaster. To remove plaster from the ceiling, the housing needs to be rotated around the hinge point 13. After rotation, both the scraper assembly 4 and the wall-breaking assembly 3 face upwards. Adjusting the telescopic device 11 allows for ceiling work. The plaster removal device includes an STM32 microcontroller, located in the control box 21 at the upper end of the housing 2, which controls the electrical equipment of the plaster removal device. The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model.
