Description

Technical Field

[0001] The utility model relates to the technical field of wall plastering for buildings, and more specifically, to a wall plastering device for buildings. Background Art

[0002] In the existing construction industry, wall plastering is a labor-intensive and time-consuming process. Traditional plastering work usually relies on manual work. Workers need to use a handheld spatula to apply plaster on the wall. This practice is not only inefficient, but also requires extremely high physical strength and endurance from workers. Long hours of work can easily lead to fatigue and physical injuries. In addition, the quality of manual plastering is often affected by the skill level of the workers, and it is difficult to ensure the uniformity and flatness of the wall.

[0003] With the development of technology, some modern construction sites have begun to use mechanized plastering machines for plastering operations. These plastering machines are usually driven by a power source (such as an electric motor or a pneumatic motor) and evenly apply the plastering material on the wall through a mechanical arm or a fixing device. However, in the existing plastering machine design, the plastering board is often a fixed structure, which means that once the plastering board is worn or needs to be replaced, the entire machine may need to be shut down for repair or replacement, which not only affects work efficiency, but also increases maintenance costs.

[0004] In addition, the angle of the lower hopper of the plastering machine in the prior art is usually fixed and cannot be adjusted according to different construction requirements, which limits the applicability of the plastering machine on walls of different heights and angles. For example, when plastering is required at a lower position, the fixed-angle lower hopper may cause material accumulation or excessive application, while at a higher position it may cause insufficient material, affecting the quality of plastering.

After the replacement is completed, the plastering plate 2 can be reinstalled back to its original position with reference to the above process.

[0041] See also Figure 1 and Figure 3 As an implementation method of the unloading device: the unloading device includes a hydraulic cylinder 31, a hydraulic rod 32 and a unloading bin 33, the hydraulic cylinder 31 is installed on the inner side of the movable frame 4, the bottom end of the hydraulic rod 32 is connected to the output end of the hydraulic cylinder 31, and the other end of the hydraulic rod 32 is movably connected to the unloading bin 33.

[0042] A connecting frame 34 is provided on the outer side of the movable frame 4 . The connecting frame 34 can be movably mounted on the movable frame 4 , and the lower material bin 33 is mounted on the inner side of the connecting frame 34 .

[0043] More specifically, when it is necessary to adjust the angle of the lower material bin 33 as required, the two hydraulic cylinders 31 installed on the movable frame 4 are opened synchronously, and the hydraulic cylinder 31 pushes the lower material bin 33 to move through the hydraulic rod 32 connected to the output end. Since the hydraulic rod 32 and the lower material bin 33 are a movable connection structure, and the lower material bin 33 is movably connected to the movable frame 4 through the connecting frame 34, when the hydraulic rod 32 pushes the lower material bin 33 to move, the angle between the lower material bin 33 and the connecting frame 34 will change. When the angle is adjusted appropriately, the hydraulic cylinder 31 can be closed.

[0044] In summary, when the overall equipment is in use or running: when the equipment needs to be used to plaster the wall, first move the equipment until it is suitable, then add the mixed plaster to the top of the plastering board 2, and then open all the cylinders 20, the cylinder 20 pushes the plastering board 2 to move through the piston rod 21 connected to the output end, so that the distance between the plastering board 2 and the wall surface changes, and then synchronously open the drive assembly 3, the drive assembly 3 drives the gear 6 connected to the output end to rotate, so that the gear 6 moves along the rack 5, so that the movable frame 4 drives the plastering board 2 to move along the rack The strip 5 rises, thereby completing the plastering work on the wall. When the plastering plate 2 needs to be replaced, the limiting sleeve 10 is first rotated, and the limiting sleeve 10 drives the movable block 14 to move, and then the movable block 14 cooperates with the fixed block 9 to squeeze the first spring 40, and then the quick-change sleeve 11 is fixed by the handle 29, and then the movable rod 15 is pressed, and then the limiting rod 13 connected to one side of the limiting sleeve 10 will pass through the limiting hole 7 opened on the limiting plate 8, and at the same time, the first push spring 12 arranged on the outer side of the limiting rod 13 will be compressed, and then the movable rod 15 will cooperate with the quick-change rod 16 to squeeze the middle setting The second push spring 30 is compressed, and the movable rod 15 drives the guide plate 18 to move, so that the guide plate 18 enters the guide groove 19. Due to the limitation of the movable rod 15 by the guide rail 24 and the guide groove 25 to prevent the movable rod 15 from rotating, and the special structural design of the guide plate 18 and the guide groove 19, when the guide plate 18 moves downward, it drives the quick-change rod 16 to rotate through the guide groove 19, so that the quick-change rod 16 and the return block 22 cooperate to compress the second spring 23, and at the same time, the quick-change rod 16 drives the matching groove 17 to move. Due to the structural design, as well as the limitation of the quick-change groove 27 and the side wall of the quick-change sleeve 11 on the quick-change block 26, when the matching groove 17 rotates with the quick-change rod 16, the third push spring 28 will reset, pushing one side of the quick-change block 26 to always fit with the side wall of the matching groove 17. At the same time, one end of the quick-change block 26 will gradually detach from the quick-change groove 27. Then, by pulling the quick-change sleeve 11 through the handle 29, the quick-change sleeve 11, the quick-change rod 16 and the movable rod 15 can be removed together, and then the plastering plate 2 can be replaced as needed. After the replacement is completed, the plastering plate 2 can be reinstalled back to its original position with reference to the above process.

[0045] When it is necessary to adjust the angle of the lower bin 33 as required, the two hydraulic cylinders 31 installed on the movable frame 4 are opened synchronously, and the hydraulic cylinder 31 pushes the lower bin 33 to move through the hydraulic rod 32 connected to the output end. Since the hydraulic rod 32 and the lower bin 33 are a movable connection structure, and the lower bin 33 is movably connected to the movable frame 4 through the connecting frame 34, when the hydraulic rod 32 pushes the lower bin 33 to move, the angle between the lower bin 33 and the connecting frame 34 will change. When the angle is adjusted appropriately, the hydraulic cylinder 31 can be closed.
