Description

Technical Field

[0001] This utility model relates to the technical field of building construction spraying devices, specifically a wall spraying device for building construction. Background Technology

[0002] Spraying is a coating method that uses a spray gun or disc atomizer to disperse the material into uniform and fine droplets with the help of pressure or centrifugal force, and then applies the coating to the surface of the object. It can be divided into air spraying, airless spraying, electrostatic spraying, and various derivative methods of the above basic spraying forms, such as high-flow-rate low-pressure atomization spraying, thermal spraying, automatic spraying, and multi-group spraying. Spraying walls can serve both decorative and protective purposes, making building walls beautiful and clean, while also protecting the building walls and extending their service life.

[0003] According to the authorized announcement number CN216340692U, a wall spraying device for house construction is disclosed, including a carrier plate. A paint tank is fixedly connected to the top right side of the carrier plate, and a third motor is fixedly connected to the middle of the right end of the paint tank. The drive end of the third motor passes through the paint tank and is fixedly connected to one end of a rotating shaft. A suction pump is fixedly connected to the middle of the top of the carrier plate, and the input end of the suction pump passes through the left end of the paint tank. The output end of the suction pump is fixedly connected to one end of a flexible hose. In this utility model, the second motor drives the rotating rod to rotate, thereby exchanging the positions of the spraying frame plate and the painting frame plate. The wall surface is then rolled again by the lifting and lowering of the slider, which can promptly spread the paint evenly. It has strong functionality and improves spraying efficiency. The third motor drives the rotating shaft and stirring rod to rotate and stir the paint evenly, preventing sedimentation and pipe blockage. During painting, the spring applies pressure to the painting cylinder, which improves the painting effect. This device is worthy of widespread promotion.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, the aforementioned equipment has certain limitations in application. When switching between coating and spraying operations, the positions of the nozzle and brush roller need to be rotated and changed, which is extremely inconvenient. Specifically, before rotation, the operator must first raise the brush roller and nozzle to a higher position to prevent the spraying frame and paint frame from breaking or being damaged during rotation due to the position being too low. Furthermore, during rotation, the material remaining in the nozzle is easily thrown out, which not only wastes material but may also pollute the working environment, thereby adversely affecting the spraying quality.

[0021] 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.

[0022] like Figures 1 to 3 As shown, this utility model provides a wall spraying device for house construction, including a mobile cart 1, a paint bucket 2, a suction pump 3, a spray head 4, a brush roller 5, a hose 6, a lifting device 7, and a lifting block 8. The paint bucket 2 is fixedly installed on the right side of the top of the mobile cart 1. The suction pump 3 is located on the left side of the paint bucket 2, with its input end connected to the paint bucket 2. The hose 6 is connected to the output end of the suction pump 3, and the spray head 4 is connected to the other end of the hose 6. The lifting device 7 is fixedly installed on the front and rear sides of the left side of the top of the mobile cart 1. The lifting block 8 is threadedly connected to the inside of the lifting device 7, and the inner side of the lifting block 8 is fixedly... A mounting plate 9 is fixedly connected to the top and bottom of the mounting plate 9, and a replacement mechanism 10 is slidably connected to the top and bottom of the mounting plate 9, respectively. The replacement mechanism 10 includes a first sliding frame 101 and a second sliding frame 102. The first sliding frame 101 and the second sliding frame 102 are slidably connected to the top and bottom of the mounting plate 9, respectively. A brush roller 5 is movably connected to the left side inside the first sliding frame 101. A nozzle 4 is fixedly installed to the left side inside the second sliding frame 102. A connecting rod 103 is movably connected to the right side inside the first sliding frame 101 and the second sliding frame 102 through a shaft. A drive assembly 104 is fixed to the top of the back of the connecting rod 103.

[0023] refer to Figure 1 and Figure 3The drive assembly 104 includes a first movable rod 1041, which is fixedly connected to the top of the back of the connecting rod 103. A first movable block 1042 is movably connected to the surface of the first movable rod 1041. An electric telescopic rod 1043 is provided on the left side of the first movable block 1042. The output end of the electric telescopic rod 1043 is fixedly connected to the first movable block 1042. A support assembly 1044 is fixedly connected to the left end of the electric telescopic rod 1043.

[0024] As a technical optimization of this utility model, by setting a drive component 104, the drive component 104 can drive the first movable block 1042 to move through the extension and retraction of the electric telescopic rod 1043, thereby driving the connecting rod 103 to move. This structure provides a power source for the adjustment of the brush roller 5 and the nozzle 4, realizes a semi-automatic drive function, and reduces the complexity and labor intensity of manual operation.

[0025] refer to Figure 1 and Figure 3 The support assembly 1044 includes a second movable block 10441, which is fixedly connected to the left end of the electric telescopic rod 1043. A second movable rod 10442 is movably connected inside the second movable block 10441. A support rod 10443 is fixedly connected to the front end of the second movable rod 10442. The bottom of the support rod 10443 is fixedly connected to the mounting plate 9.

[0026] As a technical optimization of this utility model, by setting up a support component 1044, when the electric telescopic rod 1043 extends or retracts, it will drive the second movable block 10441 connected thereto to move. The second movable rod 10442 movably connected inside the second movable block 10441 will adjust its angle as the second movable block 10441 moves. Since the front end of the support rod 10443 is fixedly connected to the second movable rod 10442 and the rear end is fixed on the mounting plate 9, the second movable rod 10442 and the support rod 10443 will bear and disperse the force of the electric telescopic rod 1043, playing a supporting and stabilizing role.

[0027] refer to Figure 1 and Figure 3 Limiting grooves 11 are provided on the front and rear sides of the bottom of the first sliding frame 101 and the front and rear sides of the top of the second sliding frame 102. Limiting sliders 12 are slidably connected inside the limiting grooves 11, and the inner side of the limiting sliders 12 is fixedly connected to the mounting plate 9.

[0028] As a technical optimization of this utility model, by setting a limiting slide groove 11 and a limiting slider 12, the first sliding frame 101 and the second sliding frame 102 are guided to move through the limiting slide groove 11 and the limiting slider 12, thereby ensuring the stability of the movement of the first sliding frame 101 and the second sliding frame 102.

[0029] refer to Figure 1 and Figure 3 A mounting bracket 13 is fixedly connected to the front right side of the top of the mobile vehicle 1. A control panel 14 is fixedly installed on the top of the mounting bracket 13. The control panel 14 is electrically connected to the electric telescopic rod 1043 via a wire.

[0030] As a technical optimization of this utility model, by setting up the mounting frame 13 and the control panel 14, a platform is provided for operators to conveniently operate and control the spraying device. Operators can control the extension and retraction of the electric telescopic rod 1043 through the control panel 14, thereby realizing the adjustment operation of the brush roller 5 and the spray head 4, which improves the convenience and flexibility of operation.

[0031] refer to Figure 1 and Figure 3 The outer side of the limiting slider 12 is movably inlaid with balls 15, and there are several balls 15 distributed at equal intervals.

[0032] As a technical optimization of this utility model, by setting the ball bearing 15, the sliding friction between the first sliding frame 101 and the second sliding frame 102 and the limiting slider 12 can be transformed into rolling friction. The frictional force of rolling friction is much smaller than that of sliding friction, thereby greatly reducing the frictional force of the first sliding frame 101 and the second sliding frame 102 during the sliding process, making their sliding smoother and easier, reducing energy loss, and also reducing wear between components.

[0033] refer to Figure 1 and Figure 3 A limiting block 16 is fixedly connected to the rear end of the first movable rod 1041 and the second movable rod 10442. The diameter of the limiting block 16 is larger than the diameter of the first movable rod 1041 and the second movable rod 10442.

[0034] As a technical optimization of this utility model, by setting a limiting block 16, the limiting block 16 can limit the first movable block 1042 and the second movable block 10441, so as to prevent them from detaching from the first movable rod 1041 and the second movable rod 10442, and ensure stable operation.

[0035] The working principle and usage process of this utility model are as follows: When the operator needs to perform spraying work, the operator uses the control panel 14 to control the output end of the electric telescopic rod 1043 to extend. This causes the electric telescopic rod 1043 to drive the connecting rod 103 to move to the right via the first movable rod 1041 and the first movable block 1042. This, in turn, causes the connecting rod 103 to drive the second sliding frame 102 to move to the left, which in turn causes the second sliding frame 102 to drive the spray head 4 to move to the left. Simultaneously, as the second sliding frame 102 moves to the left, the connecting rod 103 will also drive the first sliding frame 101 to move to the right, thus causing the first sliding frame 104 to move to the right. 1. Move the brush roller 5 to the right, thereby causing the nozzle 4 to extend and retract and the brush roller 5 to retract. After the nozzle 4 extends, the operator starts the suction pump 3, which causes the nozzle 4 to spray the paint inside the paint bucket 2 for spraying. After spraying, when the brush roller 5 is needed to smooth the wall surface, the operator controls the output end of the electric telescopic rod 1043 to retract, so that the connecting rod 103 drives the brush roller 5 to extend through the first sliding frame 101 and drives the nozzle 4 to retract through the second sliding frame 102, thereby completing the position exchange of the brush roller 5 and the nozzle 4, thus improving the convenience of the operator to adjust the brush roller 5 and the nozzle 4.

[0036] In summary, this wall spraying device for house construction, by setting up a replacement mechanism 10, changes the original rotary replacement method to a sliding replacement method, avoiding the need for the operator to pay attention to the height of the brush roller 5 and the nozzle 4 during replacement. This improves the convenience for the operator to adjust the position of the brush roller 5 and the nozzle 4, and solves the problem that the above-mentioned equipment requires rotating and changing the position of the nozzle and brush roller when switching between coating and spraying operations, which is extremely inconvenient.
