[0004] The above-mentioned existing technical solutions have the following defects: Workers directly apply the mortar to the wall using a roller brush, resulting in high labor intensity. Summary of the Utility Model

[0005] This application provides a wall plastering system in order to reduce the labor intensity of workers when applying mortar to the wall surface.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

The spraying device is fixedly connected to the material box. The other end of the spraying device is used to spray the mortar in the material box onto the wall surface. The cleaning system is connected to the spraying device in a communicating manner. The cleaning system includes a water outlet pipe, a water return pipe, and a water storage tank. The water storage tank is fixedly connected to the frame body. The water outlet pipe is arranged between the water storage tank and the material box, and both ends of the water outlet pipe are fixedly connected to the water storage tank and the material box respectively. The water return pipe is arranged between the water storage tank and the spraying device, and both ends of the water return pipe are fixedly connected to the water storage tank and the spraying device respectively. The water outlet pipe conveys the water in the water storage tank to the material box, and the material box conveys the water to the spraying device. The water after cleaning the spraying device flows back to the water storage tank through the water return pipe. The cleaning system is used to clean the spraying device.

[0008] By adopting the above solution, a material box is placed on the frame body, and mortar is placed in the material box. Then, a spraying device is set up. The spraying device is used to pump out the mortar in the material box and spray it onto the wall. In order to prevent the spraying device from being blocked by the mortar and unable to perform normal spraying operations, a cleaning system is fixedly connected to the material box. The cleaning system includes a water storage tank, a water outlet pipe, and a water return pipe. The water outlet pipe is arranged between the water storage tank and the material box, and both ends of the water outlet pipe are fixedly connected to the water storage tank and the material box respectively. The water return pipe is arranged between the water storage tank and the spraying device, and both ends of the water return pipe are fixedly connected to the water storage tank and the spraying device respectively. So that the water in the water storage tank enters the spraying device through the water outlet pipe to clean the spraying device, and then the water after cleaning flows back to the water storage tank through the water return pipe, and the spraying device is cleaned repeatedly in this cycle. By setting up the spraying device and the cleaning system for flushing the spraying device, workers do not need to use rollers to apply mortar to the wall, and the used spraying device is cleaned by the cleaning system, reducing the labor intensity of workers when applying mortar to the wall surface.

[0009] Further, the spraying device includes a spraying structure and a lifting structure. One end of the lifting structure is fixedly connected to the frame body, and the end of the lifting structure far from the frame body is fixedly connected to the spraying structure. The lifting structure is used to drive the spraying structure to lift and spray along the wall.

[0010] Further, the spraying structure includes a feeding pipe and a spray head. The spray head is provided with spray holes, and the spray head is fixedly connected to the carrying plate. The feeding pipe is arranged between the spray head and the material box. One end of the feeding pipe is inserted into the material box and fixedly connected to the material box, and the other end of the feeding pipe is fixedly connected to the spray head.

[0011] By adopting the above solution, when spraying mortar on the wall, it is necessary to spray the wall up and down so that the entire wall is covered with the sprayed mortar. Therefore, a lifting structure is set up. One end of the lifting structure is fixedly connected to the frame body, and a spraying structure is fixedly connected to the other end of the lifting structure. The spraying structure includes a feeding pipe and a spray head. One end of the feeding pipe is inserted into the material box, and the other end of the feeding pipe is fixedly connected to a spray head with spray holes. The spraying structure cooperates with the lifting structure. The spraying structure transports the mortar to the spray head through the feeding pipe, and sprays the wall surface through the spray holes. The lifting structure can drive the spray head to move up and down, thereby completing the mortar spraying operation on the entire wall.

[0012] Further, an opening and closing device is provided inside the spray head. The opening and closing device is arranged within the spray head and is used to control the opening and closing of the spraying structure on the spray head. The opening and closing device includes a sliding rod and a balance rod. The sliding rod and the balance rod are respectively arranged on both sides of the material spraying hole.

A first sliding ring is arranged on the sliding rod, and the first sliding ring is threadedly connected to the sliding rod. A second sliding ring is arranged on the balance rod, and the second sliding ring is slidably connected to the balance rod. A sealing plate is fixedly connected between the first sliding ring and the second sliding ring. A through hole is formed in the sealing plate, and the sealing plate is used to control the opening and closing of the material spraying hole.

[0013] By adopting the above scheme, when using the cleaning system to clean the spraying structure, it is necessary to seal the material spraying hole on the spray head. Therefore, an opening and closing device is arranged inside the spray head. The opening and closing system can control the opening and closing of the material spraying hole. A sliding rod and a balance rod are respectively rotatably connected on both sides of the material spraying hole. A first sliding ring is arranged on the sliding rod, and the first sliding ring is threadedly connected to the sliding rod. A second sliding ring is arranged on the balance rod, and the second sliding ring is slidably connected to the balance rod. A sealing plate is fixedly connected between the first sliding ring and the second sliding ring. When it is necessary to seal the material spraying hole, rotate the sliding rod. The sliding rod rotates along its own axis. The rotation of the sliding rod drives the first sliding ring threadedly connected to the sliding rod to move along the sliding rod. Under the limitation of the second sliding ring and the balance rod on the first sliding ring, the first sliding ring moves up and down along the sliding rod, thereby driving the sealing plate to move up and down with the first sliding ring until the sealing plate completely seals the material spraying hole.

[0014] Further, a filtering member is arranged inside the water storage tank. The filtering member is arranged between the water outlet pipe and the water return pipe and is fixedly connected to the inner wall of the water storage tank. The filtering member is used to filter the water flowing into the water storage tank through the water return pipe.

[0015] By adopting the above scheme, when using the cleaning system to clean the material tank and the spraying structure, it is necessary to repeatedly rinse the material tank and the spraying structure. Therefore, a filtering member is installed inside the water storage tank. The filtering member is arranged between the water outlet pipe and the water return pipe, so that the water flowing into the spraying structure through the water outlet pipe is filtered by the filtering member when it flows back into the water storage tank through the water return pipe, and the impurities flowing into the spraying structure again through the water outlet pipe are removed.

A sealing plate is arranged corresponding to the taking port, and one side of the sealing plate is axially connected to the side wall of the taking port.

[0017] By adopting the above solution, an access opening is provided on the side wall of the water storage tank, enabling the filter element to be taken out through the access opening for regular cleaning to prevent the filter element from being blocked. Then, a sealing plate is arranged on the access opening, and the sealing plate is used to control the opening and closing of the access opening. When the cleaning system is in operation, the sealing plate is rotated to seal the access opening and prevent water from escaping through the access opening.

[0018] Further, a locking device is arranged between the sealing plate and the access opening. The locking device includes an L-shaped rod and a retaining pin. The retaining pin is rotatably connected to the sealing plate, and the L-shaped rod is fixedly connected to the material box. When the L-shaped rod is connected to the material box, a socket is formed, and the retaining pin is inserted into and engaged with the socket.

[0019] By adopting the above solution, an L-shaped rod is fixedly connected to the side wall of the access opening. When the L-shaped rod is connected to the material box, a socket is formed. After the relative positions of the access opening and the sealing plate are determined, the retaining pin is rotated until the retaining pin is inserted into and engaged with the socket, thereby locking the relative positions of the access opening and the sealing plate.

The water outlet pipe 31 conveys the water in the water storage tank 33 to the spraying device 2, and the water after cleaning the spraying device 2 flows back to the material box 8 through the water return pipe 32. A water outlet valve 311 is fixedly connected to the water outlet pipe 31, and a water return valve 321 is fixedly connected to the water return pipe 32.

[0047] Refer to Figure 1 , Figure 2 and Figure 4, the spraying device 2 includes a spraying structure 21 and a lifting structure 22. One end of the lifting structure 22 is fixedly connected to the end of the frame body 1 away from the rollers 11, and the other end of the lifting structure 22 is fixedly connected to the spraying structure 21. The lifting structure 22 is used to control the lifting of the spraying structure 21. The lifting structure 22 includes a lifting member 221 and a load-bearing plate 222. In this embodiment, the lifting member 221 is preferably a cylinder. There are two lifting members 221. One end of each lifting member 221 is fixedly connected to the frame body 1, and the end of the lifting member 221 away from the frame body 1 is fixedly connected to the load-bearing plate 222; the spraying structure 21 includes a feeding pipe 211 and a spray head 212. The spray head 212 is arranged on the tops of the two load-bearing plates 222, and the spray head 212 is fixedly connected to each load-bearing plate 222. Spray holes 2123 are formed in the spray head 212. The feeding pipe 211 is arranged between the spray head 212 and the material box 8.

The lifting member 221 drives the spray head 212 to lift, thereby completing the overall spraying of the wall surface in the area.

[0048] Refer to Figure 2 and Figure 5 , a filtering member 331 is arranged in the water storage tank 33. The filtering member 331 is arranged between the water outlet pipe 31 and the water return pipe 32. Support bars 334 are arranged on both sides of the filtering member 331 in the water storage tank 33. The support bars 334 are fixedly connected to the side wall of the water storage tank 33. The support bars 334 are used to support the filtering member 331, and the support bars 334 make the filtering member 331 detachably connected in the water storage tank 33. The filtering member 331 is used to filter the water flowing into the water storage tank 33 through the water return pipe 32; a taking port 332 is formed in the side wall of the water storage tank 33. The taking port 332 corresponds to the filtering member 331. The taking port 332 is used to clean the filtering member 331 when the filtering member 331 is blocked by mortar; a sealing plate 333 is arranged corresponding to the taking port 332. One side of the sealing plate 333 is hinged to the taking port 332. By pushing the sealing plate 333 to rotate around the hinge axis of the sealing plate 333 and the taking port 332, the relative position relationship between the sealing plate 333 and the taking port 332 is controlled, and thus the opening and closing of the taking port 332 by the sealing plate 333 is controlled.

[0049] Refer to Figure 1 and Figure 5, a locking device 5 is arranged between the plugging plate 333 and the taking port 332. The locking device 5 includes an L-shaped rod 51 and a retaining pin 52. The retaining pin 52 is rotatably connected to the plugging plate 333. The L-shaped rod 51 is fixedly connected to the material box 8. When the L-shaped rod 51 is connected to the material box 8, a plugging slot 511 is formed. When the plugging plate 333 and the taking port 332 are in a relatively closed state, rotate the retaining pin 52, and the retaining pin 52 is inserted into the plugging slot 511 in a plugging fit manner, thereby completing the limitation of the relative position between the plugging plate 333 and the taking port 332.

[0050] Refer to Figure 1 and Figure 3 , an opening and closing device 4 is arranged in the spray head 212. The opening and closing device 4 includes a sliding rod 41, a balance rod 42 and a sealing plate 43. The sliding rod 41 and the balance rod 42 are respectively arranged on both sides of the spraying hole 2123. Both ends of the sliding rod 41 are rotatably connected to the side wall of the spray head 212. Both ends of the balance rod 42 are fixedly connected to the side wall of the spray head 212. A first sliding ring is arranged on the sliding rod 41, and the first sliding ring is threadedly connected to the sliding rod 41. A second sliding ring is arranged on the balance rod 42, and the second sliding ring is slidably connected to the balance rod 42. The sealing plate 43 is arranged between the first sliding ring and the second sliding ring. Both ends of the sealing plate 43 are respectively fixedly connected to the first sliding ring and the second sliding ring. One end of the sliding rod 41 is provided with a handrail rod 411. The handrail rod 411 passes through the side wall of the spray head 212 and is fixedly connected to the sliding rod 41. The handrail rod 411 is rotatably connected to the side wall of the spray head 212; a plurality of through holes are formed in the sealing plate 43. When using the spraying structure to spray mortar on the wall, rotate the handrail rod 411. The rotation of the handrail rod 411 drives the sliding rod 41 to rotate along its own axis. The rotation of the sliding rod 41 drives the first sliding ring threadedly connected to the sliding rod 41 to move up and down along the sliding rod 41, thereby driving the sealing plate 43 to move up and down. When the through holes are aligned with the spraying holes 2123, the mortar can be sprayed onto the wall through the spraying holes 2123.

[0051] The implementation principle of a wall plastering system according to an embodiment of the present application is as follows: When plastering a wall using this system, first close the water outlet valve 311 and the water return valve 321 to prevent the mortar in the material tank 8 from flowing into the water storage tank 33 through the water outlet pipe 31 and the water return pipe 32. Then rotate the handrail rod 411. The rotation of the handrail rod 411 drives the sliding rod 41 to rotate internally along its own axis. The rotation of the sliding rod 41 drives the first sliding ring threadedly connected to the sliding rod 41 to move up and down along the sliding rod 41, thereby driving the sealing plate 43 to move up and down. Move the sealing plate 43 until the through hole corresponds and communicates with the spraying hole 2123. Then start the pressurizing member 6. Under the action of the pressurizing member 6, the mortar in the material tank 8 is conveyed to the spray head 212 through the feeding pipe 211, and the mortar is sprayed onto the wall surface through the through hole of the spray hole and the spray hole. Then open the air cylinder. The up and down movement of the air cylinder drives the spray head 212 to move, thereby completing the spraying of the upper and lower walls in this wall area. Then push the frame body 1 to the remaining areas to be sprayed, and repeat the above steps until the spraying operation of all walls is completed. Then close the air cylinder and the pressurizing member 6.

[0052] When all the mortar in the material tank 8 is used up and the spraying structure needs to be cleaned, rotate the handrail rod 411. The rotation of the handrail rod 411 drives the sliding rod 41 to rotate internally along its own axis. The rotation of the sliding rod 41 drives the first sliding ring threadedly connected to the sliding rod 41 to move up and down along the sliding rod 41, thereby driving the sealing plate 43 to move up and down. Move the sealing plate 43 until the through hole is offset from the spraying hole 2123. The sealing plate 43 blocks the spraying hole 2123. Open the water outlet valve 311 and the water return valve 321, start the water pump 7 and the pressurizing member 6. The water in the water storage tank 33 enters the material tank 8 through the water outlet pipe 31, and then is conveyed to the feeding pipe 211 and the spray head 212 under the action of the pressurizing member 6. The water injected into the spray head 212 flows back to the water storage tank 33 through the water return pipe 32, and then passes through the filter element 331 for filtration. The filter element 331 intercepts the impurities in the water flow, and then the filtered water is pumped to the spraying device 2 through the water outlet pipe 31, and the reciprocating cycle completes the cleaning of the device. When the filter element 331 is blocked by impurities, rotate the stop pin 52 so that the stop pin 52 is separated from the insertion slot 511, open the blocking plate 333, take out the filter element 331 from the access port 332, and clean the impurities. After cleaning, place the filter element 331 in the water storage tank 33 through the access port 332 to abut against the support bar 334, then push the blocking plate 333 until the blocking plate 333 is relatively closed with the access port 332, and then rotate the stop pin 52 so that the stop pin 52 is inserted and matched with the insertion slot 511.
