Description

Technical Field

[0001] The utility model relates to the field of wall spraying, and particularly relates to a wall spraying device. Background Art

[0002] During the construction and decoration processes, most building walls need to be sprayed with paint materials (including wall paint, coatings, latex paint, etc.). At present, the paint materials are mainly sprayed on the walls through the following two methods: 1. Pure manual application, which mainly refers to manually applying the paint materials on the wall by hand, and then manually using tools to smooth the paint materials on the wall surface; 2. Semi-mechanical application, which mainly involves connecting a hose to a suction pump, then using the suction pump to suck the paint materials and spraying them onto the wall surface through the hose or spray gun, and finally manually smoothing the paint materials on the wall surface again; the first method requires manual operation throughout the process, which is relatively inconvenient to use, and when the second method sprays the paint materials on the wall, the paint materials are prone to splashing everywhere, making it difficult to smooth the subsequent paint materials.

[0003] Therefore, it is necessary to invent a wall spraying device. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A wall spraying device, including a mobile trolley and a storage cylinder, the storage cylinder is installed at the upper end of the mobile trolley, a discharge hose is installed at the lower end of one side of the storage cylinder, the other end of the discharge hose is connected to a suction pump, a delivery pipe is installed at the output end of the suction pump, a protection component is installed at the end of the delivery pipe away from the suction pump, and scraping brush components are symmetrically installed at both ends of one side of the protection component. An adjustment component is installed at one side of the upper end of the mobile trolley, and a support tooth plate is connected to the upper end of the adjustment component, and the support tooth plate is located below the protection component;

[0006] A corrugated hose is installed at the upper end of the delivery pipe, a guiding pipe is installed at the end of the corrugated hose away from the delivery pipe, and a spray head is installed at the other end of the guiding pipe, and the spray head is located inside the protection component.

[0007] Based on the above features: The paint materials can be stored in the storage cylinder in advance. When it is necessary to spray the paint materials on the wall, the mobile trolley can be first pushed to move near the wall, and the scraping brush components on one side of the protection component are made to fit on the wall. When the suction pump is started, the suction pump can suck out the paint materials in the storage cylinder through the discharge hose, and then convey them through the delivery pipe, corrugated hose and guiding pipe. Finally, the guiding pipe sprays the paint materials out through the spray head. At this time, the sprayed paint materials will cover the wall, and the scraping brush components can scrape and level the sprayed paint materials on the wall surface.

[0008] Preferably, a feed pipe is installed on one side of the upper end of the storage cylinder. Scale lines are provided on the surface of the storage cylinder. A positioning plate is installed on one side of the storage cylinder, and a positioning collar is installed at the end of the positioning plate away from the storage cylinder.

[0009] Based on the above features: The paint can be poured into the storage cylinder through the feed pipe, and the depth of the paint in the inner cavity of the storage cylinder can be observed through the scale lines. The positioning plate on one side of the storage cylinder can use the positioning collar to guide and limit the conveying pipe and the guiding pipe, so that the conveying pipe and the guiding pipe are kept in a vertical state.

[0010] Preferably, the protection component includes a protective cover and slots provided on the peripheral surface of the protective cover. Baffles are symmetrically installed on both sides of the slots, and clamping grooves are provided on the surfaces of the baffles.

[0011] Based on the above features: The protective cover can provide protection outside the nozzle, facilitating the blocking of the splashing of the paint. The slots, baffles and clamping grooves can be connected to the upper end of the support tooth plate, so that after the protective cover is rotated and adjusted, the support tooth plate can be inserted into the slots, baffles and clamping grooves for fixation.

[0012] Preferably, a through hole is provided in the middle of one end of the protective cover, and a bearing is installed on one side of the through hole.

[0013] Based on the above features: It is convenient for the protective cover to rotate and adjust outside the guiding pipe, while the guiding pipe and the nozzle remain fixed.

[0014] Preferably, the scraping component includes lugs and a scraping roller installed in the middle of the lugs. Connecting shafts are installed between the two ends of the scraping roller and the lugs.

[0015] Based on the above features: When the paint is sprayed, the sprayed paint will be located between the two scraping rollers. At this time, as the protective cover moves up and down or left and right, the scraping roller can scrape the sprayed paint flat.

[0016] Preferably, the adjusting component includes a fixed seat and a through groove provided on one side of the upper end of the fixed seat. A driving gear is arranged inside the through groove, and a driving motor is installed at the rear end of the driving gear.

[0017] Based on the above features: When the driving motor is started, the driving motor can drive the driving gear to rotate forward and backward for adjustment. At this time, as the driving gear rotates, the support tooth plate can be adjusted up or down, and the support tooth plate will also drive the protective cover, the scraping component, the nozzle and the guiding pipe to move.

[0018] Preferably, an insertion block is fixedly installed at the upper end of the support tooth plate. Activity grooves are symmetrically provided on both sides of the upper end of the support tooth plate. A moving groove is provided on the upper surface of the support tooth plate. A partition plate is installed in the middle of the inner cavity of the moving groove, and a clamping block is movably installed inside the activity groove.

[0019] Based on the above features: After the protective cover is rotated and adjusted, the insertion block at the upper end of the support tooth plate can be inserted into the inner side of the slot at the lower end of the protective cover. Subsequently, the clamping block extends out of the movable slot and is inserted into the clamping slot in the middle of the baffle for limiting.

[0020] Preferably, a buffer spring is installed between the clamping block and the partition plate. A pull plate is installed on one side of the clamping block close to the buffer spring, and the pull plate movably penetrates through the moving slot.

[0021] Based on the above features: The pull plate extends out of the moving slot movably, which is convenient for personnel to push the pull plate horizontally at the outer end. At this time, the clamping block will retract into the movable slot, and the buffer spring will be compressed and deformed. When the pull plate is released, the buffer spring will rebound and the clamping block will extend out of the movable slot.

[0022] The beneficial effects of the present utility model are:

[0023] 1. The protective cover can provide protection outside the spray head, which is convenient for blocking the sputtering of paint. When spraying paint on the wall, the scraping roller on one side of the protective cover can be first attached to the wall. If longitudinal spraying of paint is required, the protective cover can be rotated so that the scraping roller is located at the upper and lower ends of the protective cover. Subsequently, the driving gear can drive the support tooth plate to move up or down for adjustment. When the paint is sprayed out, the sprayed paint will be located between the two scraping rollers. At this time, as the protective cover moves up and down, the scraping roller can move longitudinally on the surface of the wall to scrape the sprayed paint flat. If transverse spraying of paint is required, the protective cover can be rotated again so that the two scraping rollers are located on the left and right sides of the protective cover. At this time, the moving trolley can be pushed left and right to facilitate the left and right displacement of the spray head for spraying paint. During this process, the scraping roller can also move horizontally to scrape the sprayed paint flat on the surface of the wall.

[0024] 2. It is convenient to limit and fix the protective cover. After the protective cover is rotated and adjusted, the insertion block at the upper end of the support tooth plate can be inserted into the inner side of the slot at the lower end of the protective cover. Subsequently, the clamping block extends out of the movable slot and is inserted into the clamping slot in the middle of the baffle for limiting, which not only facilitates the support and fixation of the protective cover, the scraping assembly, the spray head and the guide pipe by the support tooth plate, but also avoids the situation of self-rotation or instability after the protective cover is rotated and adjusted.

Specific embodiments

[0030] The following is a description of the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustration and explanation of the present utility model, and are not intended to limit the present utility model.

[0031] Refer to the attached Figures 1-4 drawings. A wall spraying device provided by the present utility model includes a mobile trolley 1 and a storage cylinder 2. The storage cylinder 2 is installed at the upper end of the mobile trolley 1. A discharge hose 3 is installed at the lower end of one side of the storage cylinder 2. The other end of the discharge hose 3 is connected to a suction pump 4. The output end of the suction pump 4 is installed with a delivery pipe 5. One end of the delivery pipe 5 away from the suction pump 4 is installed with a protection assembly 6. Two ends of one side of the protection assembly 6 are symmetrically installed with a brush assembly 7. An adjustment assembly 8 is installed at one side of the upper end of the mobile trolley 1. The upper end of the adjustment assembly 8 is connected to a support tooth plate 9. The support tooth plate 9 is located at the lower end of the protection assembly 6;

[0032] A corrugated hose 51 is installed at the upper end of the delivery pipe 5. One end of the corrugated hose 51 away from the delivery pipe 5 is installed with a guide pipe 52 (the corrugated hose 51 can be stretched and extended or compressed and shortened, which is convenient for the guide pipe 52 to be adjusted up and down through the corrugated hose 51). The other end of the guide pipe 52 is installed with a nozzle 53. The nozzle 53 is located inside the protection assembly 6.

[0033] The paint can be stored in advance inside the storage cylinder 2. When it is necessary to spray the paint on the wall surface, the moving trolley 1 can be first pushed to move near the wall surface, and the scraping component 7 on one side of the protection component 6 can be made to fit on the wall surface. When the suction pump 4 is started, the suction pump 4 can extract the paint in the storage cylinder 2 through the discharge hose 3, and then convey it through the conveying pipe 5, the corrugated hose 51 and the guiding pipe 52. Finally, the guiding pipe 52 sprays the paint outwards through the nozzle 53. At this time, the sprayed paint will cover the wall surface. If it is necessary to spray the paint longitudinally, the protection component 6 can be rotated so that the scraping component 7 is located at the upper and lower ends of the protection component 6. The supporting toothed plate 9 can support and limit the protection component 6 to prevent the protection component 6 from rotating and falling by itself, and the adjusting component 8 can drive the supporting toothed plate 9 to lift and adjust. When the supporting toothed plate 9 is lifted and adjusted, it will synchronously drive the protection component 6, the nozzle 53 and the guiding pipe 52 to move, facilitating the nozzle 53 to spray the paint longitudinally from top to bottom or from bottom to top. At this time, the scraping component 7 can move longitudinally to scrape the sprayed paint flat on the surface of the wall. If it is necessary to spray the paint horizontally, the upper end of the supporting toothed plate 9 can be separated from the lower end of the protection component 6, and then the protection component 6 is rotated again so that the scraping component 7 is located at the left and right ends of the protection component 6. At this time, the moving trolley 1 can be pushed to move left and right, facilitating the nozzle 53 to move left and right to spray the paint. Finally, the scraping component 7 can also move horizontally to scrape the sprayed paint flat on the surface of the wall (during this process, manual secondary smoothing can also be carried out to improve the smoothing quality of the paint).

[0034] Preferably, a feed pipe 21 is installed on one side of the upper end of the storage cylinder 2, scale lines 22 are provided on the surface of the storage cylinder 2, a positioning plate 23 is installed on one side of the storage cylinder 2, and a positioning collar 24 is installed at the end of the positioning plate 23 away from the storage cylinder 2.

[0035] The paint can be poured into the storage cylinder 2 through the feed pipe 21, and the depth of the paint in the inner cavity of the storage cylinder 2 can be observed through the scale lines 22. The positioning plate 23 on one side of the storage cylinder 2 can use the positioning collar 24 to guide and limit the conveying pipe 5 and the guiding pipe 52 to keep the conveying pipe 5 and the guiding pipe 52 in a vertical state.

[0036] Preferably, the protection component 6 includes a protective cover 61 and slots 62 provided on the peripheral surface of the protective cover 61. Baffles 63 are symmetrically installed on both sides of the slots 62, and clamping grooves 64 are provided on the surfaces of the baffles 63.

[0037] The protective cover 61 can provide protection outside the nozzle 53 to facilitate blocking the sputtering of the paint, and the slots 62, the baffles 63 and the clamping grooves 64 can be connected to the upper end of the supporting toothed plate 9, facilitating the supporting toothed plate 9 to be inserted into the slots 62, the baffles 63 and the clamping grooves 64 for fixing after the protective cover 61 is rotated and adjusted.

[0038] Preferably, a perforation 611 is formed in the middle of one end of the protective cover 61, and a bearing 612 is installed on one side of the perforation 611.

[0039] The guiding pipe 52 passes through the middle of the perforation 611 and the bearing 612, so that the spray head 53 is located inside the protective cover 61. Moreover, the protective cover 61 is connected to the guiding pipe 52 through the bearing 612, which facilitates the rotational adjustment of the protective cover 61 outside the guiding pipe 52, while the guiding pipe 52 and the spray head 53 remain fixed.

[0040] Preferably, the scraping assembly 7 includes lug ears 71 and a scraping roller 72 installed in the middle of the lug ears 71. Connecting shafts 73 are installed between both ends of the scraping roller 72 and the lug ears 71.

[0041] The scraping roller 72 is connected between the two lug ears 71 through the connecting shafts 73, and the scraping roller 72 needs to be closely attached to the wall surface. When the paint is sprayed, the sprayed paint will be located between the two scraping rollers 72. At this time, when the protective cover 61 moves up and down or left and right, the scraping roller 72 can scrape the sprayed paint flat.

[0042] Preferably, the adjusting assembly 8 includes a fixed seat 81 and a through groove 82 formed on one side of the upper end of the fixed seat 81. A driving gear 83 is arranged inside the through groove 82, and a driving motor 84 is installed at the rear end of the driving gear 83.

[0043] A groove is formed at the upper end of the fixed seat 81, and the supporting toothed plate 9 passes through the upper end of the fixed seat 81 movably. The side of the supporting toothed plate 9 with convex teeth is aligned with the through groove 82, and one side of the driving gear 83 passes through the inside of the through groove 82 and meshes with the supporting toothed plate 9. Since the driving gear 83 is connected to the shaft at the output end of the driving motor 84, when the driving motor 84 is started, the driving motor 84 can drive the driving gear 83 to rotate forward and backward for adjustment. At this time, with the rotation of the driving gear 83, the supporting toothed plate 9 can be adjusted upward or downward, and the supporting toothed plate 9 will also drive the protective cover 61, the scraping assembly 7, the spray head 53 and the guiding pipe 52 to move.

[0044] Preferably, a plug 91 is fixedly installed at the upper end of the supporting toothed plate 9. Moving grooves 92 are symmetrically formed on both sides of the upper end of the supporting toothed plate 9. A moving groove 93 is formed on the upper surface of the supporting toothed plate 9. A partition plate 94 is installed in the middle of the inner cavity of the moving groove 93. A clamping block 95 is movably installed inside the moving groove 92.

[0045] After the protective cover 61 is rotationally adjusted, the slot 62 and the baffle 63 on one side will be located at the upper end of the support tooth plate 9. At this time, the clamping block 95 can be first pushed back into the movable groove 92. Then, the support tooth plate 9 can insert the insertion block 91 at the upper end into the inner side of the slot 62, and the baffle 63 can limit the position on both sides of the upper end of the support tooth plate 9. Finally, the clamping block 95 can be released, so that the clamping block 95 extends out of the movable groove 92 and is inserted into the clamping groove 64 in the middle of the baffle 63 for limiting. When it is necessary to separate the protective cover 61 from the support tooth plate 9, only need to push the clamping block 95 back into the movable groove 92 again to disengage from the clamping groove 64.

[0047] The pull plate 952 movably extends out of the moving groove 93, which is convenient for personnel to push the pull plate 952 to translate at the outer end. At this time, the clamping block 95 will retract into the movable groove 92, and the buffer spring 951 will be squeezed and deformed. When the pull plate 952 is released, the buffer spring 951 will rebound to push the clamping block 95 out of the movable groove 92.

[0048] The using process of the utility model is as follows: The paint can be stored in the storage cylinder 2 in advance. When it is necessary to spray the paint on the wall surface, the movable trolley 1 can be first pushed to move near the wall surface, and the scraping roller 72 on one side of the protective cover 61 is attached to the wall surface. When the suction pump 4 is started, the suction pump 4 can extract the paint in the storage cylinder 2 through the discharge hose 3, and then convey it through the conveying pipe 5, the corrugated hose 51 and the guiding pipe 52. Finally, the guiding pipe 52 sprays the paint outwards through the nozzle 53. If it is necessary to spray the paint longitudinally, the protective cover 61 can be rotated so that the scraping roller 72 is located at the upper and lower ends of the protective cover 61. Then, the driving gear 83 can drive the support tooth plate 9 to move up or down for adjustment. When the paint is sprayed out, the sprayed paint will be located between the two scraping rollers 72. At this time, as the protective cover 61 moves up and down, the scraping roller 72 can move longitudinally on the surface of the wall to scrape the sprayed paint flat. If it is necessary to spray the paint horizontally, the protective cover 61 can be rotated again so that the two scraping rollers 72 are located on the left and right sides of the protective cover 61. At this time, the movable trolley 1 can be pushed to move left and right, which is convenient for the nozzle 53 to move left and right to spray the paint. During this process, the scraping roller 72 can also move horizontally to scrape the sprayed paint flat on the surface of the wall.
