Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a wall plastering device for building construction. Background Technology

[0002] In building construction, wall plastering refers to the application of cement mortar, mixed mortar, lime mortar, or concrete mortar to the wall surface as a whole. It is a traditional decorative project that uses mortar to apply to the walls, floors, ceilings, and other surfaces of a building, aiming to enhance the aesthetics and functionality of the walls.

[0003] Patent CN217711569U discloses a wall plastering device for building construction. Through the cooperation of a receiving box, a spraying assembly, a storage box, a scraper, a winding assembly, a horizontal plate, a vertical rod, and an elastic component, the receiving box is brought into contact with the wall surface. The spraying assembly then guides the mortar inside the storage box to the upper surface of the scraper. The winding assembly then moves the horizontal plate upwards on the vertical rod, simultaneously moving the scraper upwards. The scraper maintains a relatively fixed distance from the wall under the elastic force of the elastic component. As the scraper moves, the mortar falls into the receiving box below for collection. However, while this wall plastering device achieves smooth plastering when the scraper moves upwards due to the pull of the connecting rope, when moving downwards, the connecting rope does not exert a downward pull on the scraper; the scraper relies solely on its own weight to move downwards, which is insufficient for effective top-to-bottom plastering. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a wall plastering device for building construction.

[0005] A wall plastering device for building construction includes:

[0006] The base has wheels installed underneath it; a collection trough is also installed on the front side of the base; and a filter plate is installed inside the collection trough.

[0007] A storage bin located above the base; the storage bin is connected to a spray pipe via a discharge pipe;

[0008] The plastering assembly located above the base includes a limiting plate fixed to the base, a sliding plate slidably connected to the limiting plate, and a scraper detachably connected to the sliding plate; the spray pipe is arranged above the scraper; the sliding plate is driven by a motor to move up and down.

[0009] Furthermore, a first conveying pump is provided on the discharge pipe for drawing out the slurry in the storage tank and allowing it to flow into the spray pipe.

[0010] Furthermore, a return pipe is provided between the collection tank and the storage box.

[0011] Furthermore, a second conveying pump is installed on the return pipe to extract the slurry from the collection tank and allow it to flow into the storage tank.

[0012] Furthermore, the limiting plate is perpendicular to the base, and a sliding groove is provided on the front side of the limiting plate, along which the sliding plate moves up and down; the motor is fixed to the upper end face of the limiting plate.

[0013] Furthermore, limiting strips are provided on opposite sides of the slide groove, and the slide plate is provided with matching limiting grooves to prevent the slide plate from detaching from the slide groove.

[0014] Furthermore, a rack is provided on the other side of the skateboard, and a gear is connected to the output end of the motor. The rotation of the motor drives the gear to rotate, thereby driving the skateboard to move up and down.

[0015] Furthermore, a positioning groove is provided above the scraper for positioning the spray tube; the bottom surface of the positioning groove is an arc surface, which is adapted to the lower end surface of the spray tube.

[0016] Furthermore, a positioning plate is provided on the side of the slide plate for positioning the upper end face of the spray tube; the lower end face of the positioning plate is an arc surface, which is adapted to the upper end face of the spray tube.

[0017] Furthermore, the lower end face of the scraper and the lower end face of the slide plate are detachably connected by a connecting plate and bolts.

[0018] Furthermore, the collection tank is provided with an embedded edge, and the filter plate abuts against the upper surface of the embedded edge to filter the falling slurry.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This wall plastering device is designed for building construction. Before use, adjust the gear to the top of the sliding plate rack. Then, turn on the motor to rotate the gear, moving the sliding plate upwards while simultaneously spraying slurry from the nozzle. The scraper then applies the slurry for plastering. When the gear is at the bottom of the sliding plate rack, reverse the motor's rotation and simultaneously turn off the first delivery pump. The sliding plate then moves the scraper downwards, performing a second smoothing operation on the slurry, resulting in efficient wall plastering. This wall plastering device allows for one smoothing operation when the scraper moves upwards, a second smoothing operation when the scraper moves downwards, and can repeat this process multiple times.

[0021] Furthermore, a filter plate is installed in the collection tank to filter out the spilled slurry. At the same time, a return pipe is installed between the collection tank and the storage tank. When the second conveying pump is turned on, the filtered slurry in the collection tank can be extracted and flowed into the storage tank, allowing the spilled slurry to be reused, saving raw materials and avoiding waste of resources.

[0022] Furthermore, by using a motor to drive the gears to rotate, the slide plate equipped with a rack and pinion moves up and down, enabling smooth switching between upward and downward scraping operations, making operation convenient and quick. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Example 1:

[0040] like Figures 1-4 As shown, this embodiment provides a wall plastering device for building construction, including a base 1, a storage tank 2 located above the base, and plastering components. The base 1 is equipped with wheels 11, and a collection trough 12 is installed on the front side of the base 1. A filter plate 13 is installed inside the collection trough 12 to filter the slurry falling into it, facilitating its reuse. The storage tank 2 is placed above the base 1 and is connected to a spray pipe via a discharge pipe 21. A first delivery pump 22 is installed on the discharge pipe 21 to draw the slurry from the storage tank 2 and allow it to flow into the spray pipe for spraying.

[0041] In this embodiment, a plastering assembly is provided above the base 1. Specifically, the plastering assembly includes a limiting plate 3 fixed to the base 1, a sliding plate 4 slidably connected to the limiting plate 3, and a scraper 5 detachably connected to the sliding plate 4. A spray pipe 6 is provided above the scraper 5. The sliding plate 4 is driven by a motor 7 to move up and down, thereby driving the spray pipe 6 and the scraper 5 to move up and down to perform plastering operations.

[0042] Specifically, such as Figures 1-4 and Figure 7 As shown, an embedded edge 121 is provided inside the collection tank 12, and a filter plate 13 abuts against the upper end face of the embedded edge 121. The filter plate 13 has several filter holes for filtering the dropped slurry. A return pipe 23 is provided between the collection tank 12 and the storage tank 2. A second conveying pump 24 is provided on the return pipe 23, which can extract the filtered slurry from the collection tank 12 and let it flow into the storage tank 2, so that the dropped slurry can be reused.

[0043] In this embodiment, as Figures 1-6As shown, the limiting plate 3 is fixedly connected to the base 1 and perpendicular to each other. A groove 31 is provided on the front side of the limiting plate 3, and the slide plate 4 moves up and down along the groove 31. The motor 7 is fixedly connected to the upper end face of the limiting plate 3, and the output end of the motor 7 is connected to the gear 8. The slide plate 4 is a long strip-shaped structure, with its outward side being a flat surface and its inward side designed as a rack, which can mesh with the gear 8. The rotation of the motor 7 can drive the gear 8 to rotate, thereby driving the slide plate 4 to move up and down. In order to prevent the gear 8 from disengaging from the slide plate 4 when the slide plate 4 moves up and down to the edge, baffles 41 are provided at both ends of the slide plate.

[0044] Furthermore, to prevent the slide plate 4 from detaching from the slide groove 31, limiting strips 32 are respectively provided on opposite sides of the slide groove 31, and the slide plate 4 is provided with matching limiting grooves 42. Among them, the limiting strips 32 can limit the slide plate 4 and prevent it from detaching from the front side of the limiting plate 3 during the up and down movement of the slide plate 4.

[0045] In this embodiment, a positioning groove 51 is provided above the scraper 5 to position the spray pipe 6. The bottom surface of the positioning groove 51 is curved and matches the lower end surface of the spray pipe 6. To prevent the spray pipe 6 from moving left or right, baffles are also provided at both ends of the positioning groove. That is, the bottom of the spray pipe 6 is embedded in the positioning groove 51. Spray holes 61 are also provided on the spray pipe 6, and the slurry is sprayed out from the spray holes 61 to facilitate wall plastering.

[0046] More specifically, the scraper 5 is detachably connected to the bottom of the slide plate 4. The lower end face of the scraper 5 and the lower end face of the slide plate 4 are detachably connected by a connecting plate 9 and bolts. Bolt holes are provided at corresponding positions on the connecting plate 9, the lower end face of the scraper 5, and the lower end face of the slide plate 4, allowing the scraper 5 to be connected to the slide plate 4 using bolts. A positioning plate 43 is also provided on the side of the slide plate 4 for positioning the upper end face of the spray pipe 6; the lower end face of the positioning plate 42 is curved and matches the upper end face of the spray pipe 6. Therefore, with the combined action of the positioning plate 43 of the slide plate 4 and the positioning groove 51 of the scraper 5, the spray pipe 6 can be stably installed and operate stably in wall plastering operations. It is worth noting that the discharge pipe 21 and the return pipe 23 are both flexible hoses, and the length of the discharge pipe 21 is sufficient to accommodate its positional changes as it moves up and down with the spray pipe 6.

[0047] The wall plastering device for building construction provided in this embodiment requires adjusting gear 8 to the top of the rack of slide plate 4 before use. At this time, the scraper is in a lower position. Figure 1 and Figure 2 As shown. Then the motor is turned on, driving gear 8 to rotate, thus moving the slide plate upwards. At the same time, the spray pipe 6 sprays out slurry, and then the scraper 5 applies the slurry for plastering. When the gear is at the bottom end of the rack of the slide plate 4, as shown... Figure 3 and Figure 4As shown; the motor is reversed, and the first delivery pump is shut off. The slide plate 4 drives the scraper 5 downwards, achieving a second smoothing operation on the slurry. Using this wall plastering device, a first smoothing operation is performed when the scraper moves upwards, and a second smoothing operation is performed when the scraper moves downwards; this process can also be repeated multiple times. The motor drives the gears, which in turn move the slide plate equipped with racks up and down, allowing for smooth switching between upward and downward scraping operations, making operation convenient and quick.

[0048] Example 2:

[0049] An auxiliary nozzle 10 is also provided below the scraper 5, such as... Figure 8 As shown, the auxiliary spray pipe 10 is connected to another feed pipe and another delivery pump. When the drive slide plate 4 moves upward, the spray pipe 6 sprays out slurry, at which point the auxiliary spray pipe 10 stops spraying slurry, and the scraper 5 performs the plastering operation. When the drive slide plate 4 moves downward, the auxiliary spray pipe 10 sprays out slurry, at which point the spray pipe 6 stops spraying slurry, and the scraper 5 performs the plastering operation. The wall plastering device provided in this embodiment can perform the operation of spraying slurry and smoothing simultaneously when the scraper moves upward and downward.

[0050] Specifically, the auxiliary nozzle 10 is fixed below the scraper 5. Two pipe grooves 52 are integrally arranged below the scraper 5, and the pipe grooves 52 are bonded or bolted to the lower part of the scraper 5. Each pipe groove 52 contains one auxiliary nozzle 10. The auxiliary nozzle 10 can be inserted into the pipe groove 52 by slightly bending it. A gap is left between the two pipe grooves 52, which is used to fix the scraper to the slide plate 4.

[0051] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
