Description

Technical Field

[0001] This application relates to the field of home renovation technology, and in particular to an indoor building wall plastering device. Background Technology

[0002] Plastering, commonly known as "painting" or "plastering," is an important decorative and protective process in construction. Its core technique involves applying a pre-mixed mortar (usually composed of cement, lime plaster, sand, water, and appropriate additives) in layers, either manually or mechanically, to the base surface of structural components such as walls, ceilings, beams, and columns.

[0003] Chinese utility model patent CN222962422U discloses an indoor building wall plastering device, relating to the field of house decoration technology, to solve the problems of low plastering efficiency and high labor intensity in existing methods. The device includes a base, a gantry frame fixedly installed on one side of the top of the base, lifting blocks between the inner walls of the gantry frame on opposite sides, an installation plate fixedly connected to one side of the lifting block, and two fixed rods fixedly connected to one side of the installation plate. Connecting blocks a are rotatably connected to one side of each of the two fixed rods, and plastering boards are fixedly connected to one side of each connecting block a. A drive motor a drives a threaded rod to rotate, thereby driving the lifting block to move. As the lifting block moves, it causes the plastering board to move up and down repeatedly for plastering, reducing labor requirements and improving safety. Furthermore, raw materials are poured into a loading box, flowing into a feeding cylinder. A drive motor b then drives an auger to rotate, lifting the raw materials upwards and conveying them through a conveying pipe to a discharge trough, continuously supplying materials during plastering.

[0004] In actual use, when motor A drives the lifting block to move and the plastering board moves repeatedly for plastering, the material is not easily evenly distributed on the plastering board when it is transported through a single conveying pipe. It is not easy to plaster all the plastering areas on the plastering board, which means that the unplastered areas need to be plastered manually afterward, increasing the workload of personnel. Utility Model Content

[0005] In order to make the plastering device more comprehensive and thorough, less likely to miss any spots, and reduce the workload of personnel, this application provides an indoor building wall plastering device.

[0006] This application provides an indoor building wall plastering device, which adopts the following technical solution:

[0007] An indoor building wall plastering device includes a base and two mounting brackets mounted on the base, and a plastering mechanism. The plastering mechanism includes a plastering board and a plastering motor. The plastering board is slidably disposed between the two mounting brackets. The plastering motor is disposed on the side of the mounting brackets. A threaded rod is coaxially disposed on the output shaft of the plastering motor. A sliding block is threadedly connected to the threaded rod. One end of the sliding block is disposed on the plastering board. The forward and reverse rotation of the plastering motor drives the threaded rod to rotate. The rotation of the threaded rod causes the sliding block to slide. The plastering board slides vertically back and forth for plastering. The device also includes a tilting assembly, which includes a tilting plate disposed between the two mounting brackets. The tilting plate is used to tilt mortar. The tilting plate is located above the plastering board. The mortar flows onto the plastering board through the tilting plate. One end of the plastering board abuts against the wall surface. The tilting plate is used to tilt the mortar onto the plastering board.

[0008] By adopting the above technical solution, when the wall needs to be plastered, the plastering board is slidably set between two mounting brackets, and mortar is poured onto the tilting plate. The tilting plate is located above the plastering board and is used to pour mortar onto the plastering board. The mortar fills the plastering board completely. The plastering motor rotates forward and backward, driving the sliding block to slide. The sliding block slides to realize the vertical reciprocating sliding of the plastering board for plastering. When plastering, the mortar always fills the plastering board completely, making the plastering device more comprehensive and thorough, less likely to miss any spots, and reducing the workload of personnel.

[0009] Optionally, the plastering mechanism further includes a sliding plate and a push rod. A limit block is provided on one side of the sliding block, and a sliding groove is provided on the limit block. The sliding groove is slidably connected to the mounting frame. The sliding plate slides along the length direction of the mounting frame. The sliding block is located on one side of the sliding plate. The sliding block drives the sliding plate to slide. The push rod is located on the side of the sliding plate away from the mounting frame. The plastering plate is located at the end of the push rod away from the sliding plate. The push rod drives the plastering plate to slide closer to the wall.

[0010] By adopting the above technical solution, the limiting block and the mounting frame are slidably connected. The sliding block is set on one side of the sliding plate. The sliding block slides and drives the sliding plate to slide, so as to realize the vertical sliding of the plastering board for plastering. The push rod makes one end of the plastering board abut against the wall, so that the plastering thickness is consistent when the plastering board is plastered.

[0011] Optionally, the push rod position is an electric push rod.

[0012] By adopting the above technical solution, the electric push rod reduces the precision requirements when placing the plastering device, and the electric push rod makes the plaster board abut against the wall surface.

[0013] Optionally, the tilting assembly further includes a fixed plate and two telescopic columns. The fixed plate is slidably disposed between two mounting frames and slides along the length direction of the mounting frames. Both telescopic columns are disposed on the fixed plate. The tilting plate is rotatably disposed at the end of the fixed plate away from the telescopic columns. The telescopic columns extend and retract in the same direction as the length direction of the mounting frames.

[0014] By adopting the above technical solution, the fixed plate is slidably set between the two mounting brackets, and the telescopic column is set on the fixed plate. The telescopic column is used to adjust the tilt angle of the tilt plate.

[0015] Optionally, a connecting block is provided on the fixing plate, and one side of the connecting block is disposed on the limiting block. The sliding of the limiting block causes the connecting block to slide, and the sliding plate causes the fixing plate to slide.

[0016] By adopting the above technical solution, the sliding block slides and drives the connecting block to slide. That is, when the plastering board slides, the inclined plate slides synchronously. When the inclined plate touches the top of the mounting frame, the plastering board continues to slide. At this time, the telescopic column makes the inclined plate perpendicular to the mounting frame, thereby increasing the plastering height of the plastering board.

[0017] Optionally, guard plates are provided on both sides of the tilting plate.

[0018] By adopting the above technical solution, the mud is prevented from detaching from the inclined plate by using a protective plate.

[0019] Optionally, it also includes a mixing tank and a feeding mechanism. The mixing tank is mounted on a base, and the feeding mechanism is positioned between the mixing tank and the tilting plate. The feeding mechanism includes a conveying pipe and a threaded feeding rod. The mixing tank has a discharge port, and the conveying pipe is connected to the discharge port. The threaded feeding rod is positioned inside the conveying pipe. A feeding motor is mounted at one end of the conveying pipe, and one end of the threaded feeding rod is coaxially mounted at the output end of the feeding motor. The feeding motor drives the threaded feeding rod to rotate to achieve concrete feeding. A connecting pipe is mounted at the end of the conveying pipe away from the mixing tank. The connecting pipe is used for material discharge and is located above the tilting plate.

[0020] By adopting the above technical solution, the mixing tank mixes the mud. After the mud is mixed, the feeding motor drives the threaded feeding rod to rotate and transport the mud to the connecting pipe. The mud falls onto the inclined plate through the connecting pipe, which facilitates the plastering of the plastering device. The plastering device is easy to feed and does not require manual feeding, thus automating the plastering and feeding process.

[0021] Optionally, the base is provided with several sets of rollers at its bottom.

[0022] By adopting the above technical solution, the rollers facilitate the movement of the plastering device.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When the wall needs to be plastered, the mortar is poured onto the pouring plate. The pouring plate is used to pour the mortar onto the plastering plate. The mortar fills the plastering plate completely. When plastering, the mortar always fills the plastering plate completely, so that the plastering device can plaster more thoroughly and completely, and is less likely to miss any spots, thus reducing the workload of personnel.

[0025] 2. The telescopic column is used to adjust the tilt angle of the inclined plate;

[0026] 3. The mixing drum and feeding mechanism make it easy to feed mud without manual feeding, thus automating the plastering and feeding process. Attached Figure Description

Detailed Implementation

[0033] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] Embodiment 1 of this application discloses an indoor building wall plastering device. (Refer to...) Figure 1 , Figure 2 , Figure 3An indoor building wall plastering device includes a base 100 and two mounting brackets 1 fixed on the base 100. The device also includes a plastering mechanism 2, which comprises a plastering plate 21 and a plastering motor 22. The plastering plate 21 is located between the two mounting brackets 1. Two plastering motors 22 are fixed, each fixed to the side of a mounting bracket 1. A threaded rod 31 is coaxially fixed to the output shaft of each plastering motor 22. A sliding block 32 is threadedly connected to the threaded rod 31. A limit block 33 is fixed to one side of the sliding block 32, and a sliding groove 34 is formed on the limit block 33, which is slidably connected to the mounting bracket 1.

[0035] Reference Figure 1 , Figure 2 , Figure 3 The plastering mechanism 2 also includes a sliding plate 23 and a push rod 24. A sliding block 32 is fixed to one side of the sliding plate 23. The sliding plate 23 slides along the length of the mounting frame 1, and the sliding block 32 causes the sliding plate 23 to slide. The push rod 24 is fixed to the side of the sliding plate 23 away from the mounting frame 1. The push rod 24 is an electric push rod. The plastering plate 21 is fixed to the end of the push rod 24 away from the sliding plate 23. When the plastering device is placed at the area to be plastered, if the plastering plate 21 does not touch the wall, the control system sends a command to drive the push rod 24, causing the plastering plate 21 to slide closer to the wall until one end of the plastering plate 21 touches the wall. The plastering motor 22 rotates forward and reverse, driving the threaded rod 31 to rotate. The rotation of the threaded rod 31 causes the sliding block 32 to slide, and the plastering plate 21 slides vertically back and forth for plastering.

[0036] Reference Figure 1 , Figure 2 , Figure 3 An indoor building wall plastering device further includes a tilting assembly 4, which includes a tilting plate 41 and a fixing plate 42. The tilting plate 41 is disposed between two mounting brackets 1 and is used to tilt mortar. The tilting plate 41 is located above the plastering board 21, and the mortar flows onto the plastering board 21 through the tilting plate 41. One end of the plastering board 21 abuts against the wall surface. The tilting plate 41 is used to tilt mortar onto the plastering board 21. One end of the tilting plate abuts against the top of the plastering board 21 to achieve tilting limit of the tilting plate. Protective plates 36 are fixed on both sides of the tilting plate 41. The fixing plate 42 is slidably connected between the two mounting brackets 1. The mounting brackets 1 are provided with a sliding groove for the fixing plate 42 to slide along the length direction of the mounting brackets 1.

[0037] Reference Figure 1 , Figure 2 , Figure 3The tilting assembly 4 also includes two telescopic columns 43, both of which are fixed to the fixed plate 42. The telescopic columns 43 are electrically operated. The control system controls the telescopic distance of the electrically operated telescopic columns 43. The tilting plate 41 is rotatably connected to the end of the fixed plate 42 away from the telescopic columns 43. The telescopic direction of the telescopic columns 43 is the same as the length direction of the mounting frame 1, ensuring that the mortar always fills the plastering plate 21 completely during plastering, making the plastering more thorough and complete. A connecting block 35 is fixed to the fixed plate 42. One side of the connecting block 35 is fixed to the limiting block 33. The sliding of the limiting block 33 causes the connecting block 35 to slide, and the sliding plate 23 causes the fixed plate 42 to slide.

[0038] Reference Figure 1 The base 100 has several sets of rollers 81 fixed to its bottom. Two feet 82 are rotatably connected to the bottom of the base 100, which restrict the movement of the plastering device during operation. Supports are fixed to the bottom of the two mounting brackets 1, and these supports rest against the ground.

[0039] The implementation principle of an indoor building wall plastering device according to Embodiment 1 of this application is as follows: When the wall needs plastering, the plastering device is placed close to the wall, the foot support 82 is opened to fix the plastering device, the electric push rod 24 drives the plastering board 21 to abut against the wall, an appropriate amount of mortar is manually taken and poured onto the pouring plate 41, the mortar is poured onto the plastering board 21 through the pouring plate 41, the mortar fills the plastering board 21, and the remaining mortar accumulates on the pouring plate 41, the plastering motor 22 rotates forward and reverse to drive the sliding block 32 to slide, the sliding block 32 slides and drives the plastering board 21 to be plastered vertically, the connecting block 35 is fixed to the sliding block 32, and when the plastering board 21 slides through the connecting block 35, the fixed block 35 is used to fix the plastering board 21 to the wall. Simultaneously, the fixed block slides, and the tilting plate 41 slides with the plastering plate 21 to achieve uninterrupted material supply. When the tilting plate 41 abuts against the top of the mounting frame 1, the control system controls the electric push rod 24 to compress, making the tilting plate 41 perpendicular to the mounting frame 1. At this time, the plastering plate 21 continues the plastering operation. When the plastering plate 21 reaches the highest point of the plastering device, the control system controls the electric telescopic column 43 to retract. After cleaning the mortar in the plastering plate 21, the electric telescopic column 43 makes the plastering plate 21 abut against the wall again. When the plastering plate 21 slides towards the base 100, the plastering plate 21 performs leveling operations on the plastered area. The tilting plate 41 makes the plastering device plaster more comprehensive and thorough, less likely to miss any spots, and reduces the workload of personnel.

Figure 4 , Figure 5The difference between this embodiment and Embodiment 1 is that the indoor building wall plastering device further includes a mixing tank 5 and a feeding mechanism 6. The mixing tank 5 is fixed on a base 100, and a mixing motor 9 is fixed on the mixing tank. A mixing blade (not shown in the figure) is coaxially fixed on the output shaft of the mixing motor 9. The mixing motor 9 drives the mixing blade to rotate, and the mixing blade is used to mix the slurry in the mixing tank. The feeding mechanism 6 is located between the mixing tank 5 and the tilting plate 41. The feeding mechanism 6 includes a conveying pipe 61 and a threaded feeding rod 62. The mixing tank 5 has a discharge port 71, and the conveying pipe 61 is connected to the discharge port 71. The threaded feeding rod 62 is fixed inside the conveying pipe 61. A feeding motor 72 is fixed to one end of the conveying pipe 61, and one end of the threaded feeding rod 62 is coaxially fixed to the output end of the feeding motor 72. The feeding motor 72 drives the threaded feeding rod 62 to rotate to realize concrete feeding. A connecting pipe 73 is fixed to the end of the conveying pipe 61 away from the mixing tank 5. The connecting pipe 73 is used for discharging material and is located above the tilting plate 41. The mortar is sprayed out through the connecting pipe 73 and falls into the tilting plate 41 by the feeding mechanism 6. The feeding mechanism 6 makes it easy to control the amount of mortar transported, which does not easily cause mortar waste and facilitates the plastering device to plaster. At the same time, the plastering device is easy to feed, and no manual feeding is required, so the plastering and feeding are automated.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
