[0016] The present invention will be further described in detail below with reference to the accompanying drawings.

[0017] like Figure 1 As shown, a fully automatic circular plastering machine includes a pair of mounting frames 1, a pair of lifting plates 2, a power component 3, a plastering component 4, and a drive component 5.

[0018] like Figure 1 , Figure 2 As shown, a pair of mounting brackets 1 are vertically installed on the ground and distributed on both sides of a circular column. The mounting bracket 1 includes a support frame 11 and a pair of vertical rods 12. The support frame 11 is installed on the ground, and the pair of vertical rods 12 are vertically installed on both sides of the support frame 11.

[0019] like Figure 2 , Figure 3 As shown, a pair of lifting plates 2 are arranged horizontally and vertically slidably connected to the vertical rod 12. The inner side of the lifting plate 2 is provided with a semi-circular notch 21, and after interlocking with each other, they surround the circular column. The inner wall of the notch 21 is 1-2 cm away from the surface of the circular column.

[0020] like Figure 2 , Figure 3 As shown, a semi-circular rubber plate 22 is provided on the inner side of the lifting plate 2. The rubber plate 22 is located in the notch 21 and is used to abut against the surface of the circular column and to stably support the cement mortar around the circular column.

[0021] like Figure 2 , Figure 3As shown, the power assembly 3 is used to control the vertical sliding of the lifting plate 2. The power assembly 3 includes a rotating shaft 31, a second gear 32, a mounting rack 33, a second mounting base 34, a second motor 35, and a sprocket assembly 36.

[0022] like Figure 2 , Figure 3 As shown, the rotating shaft 31 is horizontally connected to the end of the lifting plate 2, the second gear 32 is disposed at both ends of the rotating shaft 31, and the rack 33 is disposed on the outer wall of the vertical rod 12 and meshes with the second gear 32.

[0023] like Figure 2 , Figure 3 As shown, the second mounting base 34 is mounted on the lifting plate 2, the second motor 35 is mounted on the second mounting base 34, and the sprocket assembly 36 is located between the second motor 35 and the rotating shaft 31, and is used to control the rotation of the rotating shaft 31.

[0024] like Figure 2 , Figure 3 As shown, both ends of the lifting plate 2 are horizontally rotatably connected to limit shafts 37, which are located inside the support frame 11. Both ends of the limit shafts 37 are provided with guide wheels 38, which abut against and clamp the inner wall of the vertical rod 12.

[0025] like Figure 1 , Figure 3 As shown, the plastering assembly 4 includes an installation half-cylinder 41 and a scraper 42. The installation half-cylinder 41 is semi-circularly mounted on the lifting plate 2 and interlocks with each other to surround the circular column. The scraper 42 has an L-shaped cross-section and is semi-circularly arranged inside the installation half-cylinder 41.

[0026] like Figure 3 As shown, the scraper blades 42 interlock and surround the circular column, with the inner wall of the scraper blades 42 flush with the inner wall of the notch 21. The horizontal section of the scraper blades 42 is rotatably connected to the mounting half-cylinder 41, forming an annular channel between the scraper blades 42, the mounting half-cylinder 41, and the lifting plate 2.

[0027] like Figure 3 As shown, a material inlet 43 is provided through the installation half-cylinder 41, and multiple elongated slurry outlets 44 are vertically arranged and spaced apart on the inner side of the scraper plate 42. Multiple hollow support blocks 45 are evenly distributed on the inner side of the scraper plate 42, and the support blocks 45 abut against the inner side of the installation half-cylinder 41 to achieve stable support between the installation half-cylinder 41 and the scraper plate 42.

[0028] like Figure 3 As shown, the drive assembly 5 is used to control the rotation of the scraper 42. The drive assembly 5 includes a gear ring 51, a first mounting base 52, a first motor 53, and a first gear 54.

[0029] like Figure 3 As shown, the toothed ring 51 is disposed on the upper outer wall of the scraper plate 42, and the first mounting base 52 is disposed on the lifting plate 2. The first motor 53 is disposed on the first mounting base 52, and the first gear 54 is disposed on the first motor 53 and meshes with the toothed ring 51.

[0030] When plastering is required on the outer surface of the circular column, move the two mounting brackets 1 to both sides of the circular column, then interlock the pair of lifting plates 2, and fix the pair of lifting plates 2 so that the notch 21 on the lifting plate 2 is circular and surrounds the outer wall of the circular column. Then measure the distance between the inner wall of the notch 21 and the outer wall of the circular column, so that the axial direction of the notch 21 is coaxial with the circular column, and fix the mounting brackets 1 to the ground.

[0031] When the lifting plates 2 interlock, they also cause the mounting half-cylinders 41 to interlock. Then, screws are used to fix the outer walls of the pair of mounting half-cylinders 41, forming a circular ring. At the same time, the scraper plates 42 interlock and surround the circular column in a ring shape. The scraper plates 42 can also rotate along the circular direction of the mounting half-cylinders 41.

[0032] Then, the second motor 35 drives the sprocket assembly 36 to rotate, thereby driving the rotation of the shaft 31. At this time, the shaft 31 drives the second gear 32 to rotate synchronously, and with the cooperation of the second gear 32 and the rack 33, the entire lifting plate 2 can slide vertically. Simultaneously, under the clamping action of the limiting shaft 37 and the guide wheel 38, the lifting plate 2 is restricted to sliding stably only vertically, preventing wobbling or jerking and ensuring the stability of the lifting plate 2 during the lifting process.

[0033] When the lifting plate 2 moves to the highest position of the circular column, the pump pipe is connected to the injection port 43, so that the cement mortar can enter the annular channel formed between the scraper plate 42, the installation half cylinder 41 and the lifting plate 2 along the injection port 43. Then the cement mortar is discharged outward along the outlet 44. At the same time, under the support of the rubber plate 22, the gap between the scraper plate 42 and the circular column is slowly filled with cement mortar.

[0034] Then, the first motor 53 is controlled to drive the first gear 54 to rotate, which in turn drives the gear ring 51 to rotate. This causes the scraper 42 to slowly rotate along the circumference of the mounting half-cylinder 41. At this time, the inner wall of the scraper 42 is used to automatically smooth the cement mortar on the outer surface of the circular column. Subsequently, the lifting plate 2 is controlled to move downward a certain distance to achieve automatic smoothing of the cement mortar on the surface of the circular column for the next distance, and to evenly apply the cement mortar to the outer surface of the circular column.

[0035] Therefore, by setting up a lifting plate 2 that can move vertically on the surface of a circular column, and setting a ring-shaped plastering component 4 on the lifting plate 2, the plastering component 4 is used to evenly rotate and apply cement mortar to the surface of the circular column, thereby realizing automatic plastering and uniform plastering operations, and improving plastering efficiency and plastering quality.

[0036] Meanwhile, by setting an injection port 43 on the plastering component 4 that can be connected to a pump pipe, and setting a grout outlet 44 on the inner side, cement mortar can be automatically injected into the inner side of the plastering component 4, thereby realizing automatic cement mortar supply and plastering operation.

[0037] The specific embodiments are merely illustrative of the present invention and are not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
