[0002] Wall paint forms a protective film on the wall to prevent the wall from moisture, mold, cracking, etc., thereby extending the service life of the wall.

[0003] At present, when painting a wall, it is mainly done manually. When painting, a paint roller is inserted into a paint bucket to be dipped in wall paint, and then the paint roller is rolled on the wall to achieve the painting operation on the wall.

[0004] However, when painting walls, many layers of paint are applied, the workload is large, and the intensity of painting is difficult to quantify and control, resulting in differences in film quality in different areas of the same wall, which can easily affect the moisture-proof and crack-resistant performance of the wall. Summary of the invention

[0005] In order to reduce the differences in film quality in different areas of a wall, the present application provides a wall construction robot.

[0006] The present application provides a wall construction robot, which adopts the following technical solution: A wall construction robot comprises a mounting seat, wherein a driving wheel is arranged at the bottom of the mounting seat; The mounting seat is provided with a support column, the support column is provided with a support arm which slides up and down, and the support column is provided with a driving component which drives the support arm to slide up and down; A support seat is provided on the side of the support arm away from the support column, and a paint brushing portion is provided on the side of the support seat facing away from the support arm; A receiving groove is provided in the middle of the paint brushing part, and the support seat is provided with a plurality of paint guns located in the receiving groove; A paint box is arranged on the mounting seat, and the paint box is provided with a paint delivery pipe connected to the paint gun; A paint supply component is arranged in the paint box, and the paint supply component supplies paint to the paint gun through the paint supply pipe; The support seat is provided with mounting grooves symmetrically arranged in the upper and lower parts, and the receiving groove is located between the mounting grooves; An inflatable ball is arranged in the mounting groove and corresponds to the inflatable ball in a one-to-one manner. The outer circumference of the inflatable ball is wrapped with a paint cloth. The paint brushing part is provided with paint holes that correspond to and communicate with the mounting grooves in a one-to-one manner. An extrusion assembly is disposed on the support seat, and the extrusion assembly extrudes the inflatable ball until the paint hole is filled; When the support seat abuts against the wall and moves up and down, the paint cloth slides on the surface of the inflatable ball.

The paint gun array is arranged in the receiving slot to pre-spray the wall at a fixed point to form a paint reserve layer and improve the uniformity of the final coating. Then, by sliding the support arm up and down, the paint gun and the paint cloth can be fully covered in the vertical direction, and the continuous painting operation within the height range of the wall can be automatically completed, reducing the difference in film quality in different areas of the wall.

The output shaft of the driving motor 41 is fixedly connected to the reciprocating screw 42 and is coaxially arranged. When the driving motor 41 is started, the reciprocating screw 42 is driven to rotate. At this time, the reciprocating screw 42 drives the support arm 3 to move up and down reciprocatingly.

[0032] See also Figure 3 and Figure 4 The support arm 3 is fixedly connected to a support seat 5 on the side away from the support column 2. The support seat 5 is a rectangular plate-like structure. The length direction of the support seat 5 extends in the horizontal direction and is perpendicular to the length direction of the support column 2. The side of the support seat 5 facing away from the support arm 3 is a paint brushing part 51. A receiving groove 52 is provided in the middle of the paint brushing part 51. The receiving groove 52 extends in the horizontal direction, and the extension direction of the receiving groove 52 is perpendicular to the support column 2. The support seat 5 is rotatably connected to a rotating shaft 55. The central axis of the rotating shaft 55 extends in the vertical direction.

A paint gun 53 is fixedly connected to the rotating shaft 55. The paint gun 53 corresponds to the rotating shaft 55 one by one, and the paint gun 53 can be turned over in the horizontal direction. A connecting pipe with a hose structure is fixed between the paint guns 53 to achieve mutual communication between the paint guns 53.

[0033] The wall construction robot also includes a paint box 6 and a paint supply assembly 7. The paint box 6 is fixedly connected to the top of the mounting base 1. A paint hole 511 is provided in the paint box 6 for storing wall paint. A paint delivery pipe 61 of a hose structure is provided on the paint box 6. The side of the paint delivery pipe 61 away from the paint box 6 is connected and fixed to the connecting pipe. The paint supply assembly 7 is provided in the paint box 6 and is used to supply paint to the paint gun 53 through the paint delivery pipe 61.

[0034] The paint supply assembly 7 includes a paint pump 71 and a paint pipe 72. The paint pump 71 is fixed on the outer wall of the top of the paint box 6. The paint pipe 72 extends into the paint box 6 and is connected to the paint hole 511. The end of the paint pipe 72 away from the paint box 6 is connected to the paint extraction port fixed to the paint pump 71, and the end of the paint delivery pipe 61 away from the connecting pipe is connected to the paint outlet fixed to the paint pump 71. When in use, the paint pump 71 is started. At this time, the paint pump 71 extracts the wall paint in the paint hole 511 through the paint pump 72, and then delivers the wall paint to the connecting pipe through the paint delivery pipe 61, and then distributes the wall paint to each paint gun 53 through the connecting pipe, and finally the paint gun 53 sprays the wall paint onto the wall. When in use, the sliding mounting seat 1 is to the position against the wall, and then the wall paint is sprayed out through the paint gun 53 so that the wall paint covers the wall.

[0035] A control column 56 is slidably connected in the support arm 3 and the support column 2. One end of the control column 56 extends into the receiving groove 52. A connecting ring 561 is connected between the side of the control column 56 away from the support column 2 and one of the paint guns 53. When the control column 56 approaches or moves away from the support column 2, the paint gun 53 is turned over through the connecting ring 561, and then the other paint guns 53 are driven to enter the turning state through the connecting pipe. A limiting block 562 is fixedly connected to the outer wall of the control column 56. A limiting groove 34 is opened in the support arm 3. The limiting groove 34 extends along the length direction of the support arm 3. The limiting block 562 is slidably connected in the limiting groove 34.

[0036] The support arm 3 is provided with an arc block 31, which is fixedly connected to the groove wall of the connecting groove 21 away from the groove opening, and the arc convex side of the arc block 31 is arranged toward the groove opening of the connecting groove 21. There are multiple arc blocks 31 and they are evenly spaced in the vertical direction. The support arm 3 is provided with a slide groove 32, which extends in the vertical direction. When the support arm 3 slides up and down, the arc block 31 slides through the slide groove 32. The support arm 3 is provided with an elastic driving member, which is a driving spring 33. The driving spring 33 is installed in the limiting groove 34, and one end of the driving spring 33 abuts against the side of the limiting block 562 close to the support seat 5, and the other end abuts against the groove wall of the limiting groove 34. When the driving spring 33 is elastically released, the driving control column 56 protrudes into the slide groove 32 until the side of the control column 56 away from the paint gun 53 abuts against the groove wall of the connecting groove 21 away from the groove opening. When the support arm 3 slides up and down, the control column 56 first slides on the wall of the connecting groove 21. When the control column 56 slides from the wall of the connecting groove 21 to the arc-shaped convex side of the arc block 31, the control column 56 first slides into the support arm 3, so that the driving spring 33 enters a compressed state. Then, when the control column 56 slides from the arc-shaped convex side of the arc block 31 to the wall of the connecting groove 21, the driving spring 33 is elastically released, pushing the control column 56 to slide out of the support arm 3 until it abuts against the wall of the connecting groove 21 away from the notch. When the control column 56 is slidably connected, the paint gun 53 is driven to flip through the connecting ring 561, thereby increasing the paint spraying range of the paint gun 53 on the wall.

[0037] The support base 5 is provided with mounting grooves 54 , which are arranged symmetrically in two groups up and down. Each group of mounting grooves 54 has a plurality of mounting grooves 54 and are evenly spaced along the length direction of the support base 5 . The upper and lower groups of mounting grooves 54 are staggered, and the paint hole 511 is located between the two groups of mounting grooves 54 .

[0038] The wall construction robot also includes an inflatable ball 8 and an extrusion assembly 9. The inflatable ball 8 is installed in the mounting groove 54 and corresponds to each other. The inflatable ball 8 adopts a rubber ball structure, and the interior of the inflatable ball 8 is hollow and filled with air. A sliding membrane 82 is wrapped on the outer surface of the inflatable ball 8, and the sliding membrane 82 is interactively connected with the inflatable ball 8. A paint cloth 81 is wrapped on the outer surface of the sliding membrane 82, and the paint cloth 81 is slidably connected with the sliding membrane 82. The paint brushing part 51 is provided with a paint hole 511, and the paint hole 511 is a trumpet structure. The paint hole 511 corresponds to the mounting groove 54 one by one, and the hole on the side with a smaller diameter of the paint hole 511 is connected to the mounting groove 54. The connecting hole of the paint hole 511 and the mounting groove 54 is a connecting hole, and the diameter of the hole on the side of the paint hole 511 away from the mounting groove 54 is greater than the distance between two adjacent paint holes 511 at the same horizontal height. A limiting ball 83 is arranged in the inflatable ball 8, and the diameter of the limiting ball 83 is smaller than the diameter of the connecting hole, so as to reduce the possibility of the inflatable ball 8 detaching from the mounting groove 54.

[0039] The extrusion component 9 is arranged on the support seat 5. When in use, the extrusion component 9 squeezes the inflatable ball 8 so that part of the inflatable ball 8 is squeezed into the paint hole 511 until the paint hole 511 is filled. At this time, the paint cloth 81 on the outer surface of the inflatable ball 8 is in contact with the wall. When the support arm 3 slides up and down, the paint cloth 81 slides on the wall, and the friction between the wall and the paint cloth 81 drives the paint cloth 81 to slide, driving the paint gun 53 to spray wall paint on the wall, so that the wall paint is evenly distributed on the wall; at the same time, when the mounting seat 1 moves back and forth along the wall, the mounting seat 1 does not need to move away from the wall first, and then approach the wall after the mounting seat 1 moves back and forth. At this time, the mounting seat 1 can directly move back and forth to adjust the position of wall painting, which greatly reduces the tediousness of wall painting and improves the speed of wall painting.

[0040] See also Figure 5 and Figure 6 The extrusion assembly 9 includes an extrusion plate 91 and an extrusion bolt 92. An extrusion groove is provided in the support seat 5.

The extrusion plate 91 is slidably connected to the extrusion groove, and the extrusion plate 91 corresponds to the extrusion groove. A linkage bar 911 is slidably connected to the support seat 5, and the two ends of the linkage bar 911 are respectively fixedly connected to the upper and lower extrusion plates 91, so that the upper and lower extrusion plates 91 are linked to each other. The paint cloth 81 (the paint cloth 81 is in Figure 4 The extrusion bolt 92 is threadedly connected to the support seat 5, and the end of the extrusion bolt 92 is rotatably connected to one of the extrusion plates 91 close to the support arm 3.

[0041] See also Figure 4 and Figure 6When in use, the extrusion bolt 92 is rotated to drive the extrusion plate 91 to slide, so that the extrusion plate 91 can be close to or away from the support column 2; when the extrusion plate 91 is away from the support column 2, the extrusion plate 91 squeezes the inflatable ball 8 and squeezes the inflatable ball 8 into the paint hole 511; when the extrusion plate 91 is away from the inflatable ball 8, the side of the inflatable ball 8 close to the support column 2 loses the extrusion force, and part of the air in the inflatable ball 8 in the paint hole 511 flows back, causing the inflatable ball 8 to retract into the installation groove 54.

[0042] See also Figure 7 and Figure 8 , the extrusion plate 91 is rotatably connected to the rotating roller 912, and the two rotating rollers 912 are symmetrically arranged up and down. The extrusion plate 91 is slidably penetrated by a toggle belt 913, which is connected end to end and sleeved on the outer peripheral side of the two groups of rotating rollers 912 in the same group. There are multiple toggle belts 913 and they are spaced apart along the axial direction of the rotating rollers 912. The toggle belts 913 correspond to the inflatable ball 8 one by one.

There are two rotating shafts 35 and they are spaced apart up and down. The rotating shafts 35 protrude from the outside of the support arm 3, and the central axis of the rotating shaft 35 is perpendicular to the length direction of the support arm 3. A support groove 22 is provided on the vertical side wall on one side of the connecting groove 21. The rotating shaft 35 protrudes into the supporting groove 22. When the support arm 3 moves up and down, the rotating shaft 35 slides up and down in the supporting groove 22. A connecting gear 36 is fixedly connected to the rotating shaft 35, and the connecting gear 36 slides up and down in the supporting groove 22. A connecting rack 23 is fixedly connected to the vertical groove wall of the support groove 22 near the notch on one side of the connecting groove 21, and the connecting gear 36 meshes with the connecting rack 23. When the support arm 3 moves up and down, the connecting gear 36 cooperates with the connecting rack 23 to drive the rotating shaft 35 to rotate. A linkage belt 37 is slidably inserted into the support arm 3 and the support seat 5 (the linkage belt 37 is Figure 8 There are two linkage belts 37 and they correspond to the rotating shafts 35 one by one.

The support seat 5 is provided with a tension spring 571. The tension spring 571 drives the tension block 57 to slide, so that the tension block 57 tensions the linkage belt 37, so that the linkage belt 37 adapts to the position of the extrusion plate 91.

[0045] The implementation principle of a wall construction robot in the embodiment of the present application is: When painting the wall, first move the mounting seat 1 to abut the wall, then rotate the extrusion bolt 92 so that the extrusion plate 91 squeezes the inflatable ball 8 until the inflatable ball 8 fills the paint hole 511, and the paint cloth 81 abuts the wall; then start the drive motor 41 to drive the support arm 3 to slide up and down, and start the paint pump 71 at the same time so that the paint gun 53 sprays the wall paint on the wall. Then when the support arm 3 moves up and down, the paint cloth 81 slides on the wall, and the paint cloth 81 is stained with wall paint, and the wall is painted, so that the wall paint is evenly distributed on the wall, reducing the difference in film quality in different areas of the wall. After that, the mounting seat 1 can be directly slid along the extension direction of the wall, so that the paint cloth 81 paints different parts of the wall, without pausing the paint pump 71 and moving away from the wall, until the position adjustment is completed and then approaching the wall, which greatly improves the speed of wall painting and reduces the tediousness of painting.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
