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.

[0023] Please see Figures 1-4 In this embodiment of the utility model, a plastering thickness control device includes a base frame 3. Guide mechanisms 7 are fixedly installed at both ends of one side of the base frame 3. A lifting mechanism 12 is movably connected to the guide mechanism 7. A top frame 9 is fixedly connected to the top of the guide mechanism 7. A third electric cylinder 33 is fixedly installed on the top of the base frame 3 between the guide mechanisms 7. The top of the movable end of the third electric cylinder 33 is fixedly connected to the bottom of the top frame 9. A housing 5 is fixedly installed on the top of the base frame 3. A winch 36 is fixedly installed inside the housing 5. Traction ropes 8 are wound on the winding discs at both ends of the winch 36. Two second guide wheels 35 are symmetrically rotatably connected to both sides of the top frame 9. The traction ropes 8 are wound around the corresponding second guide wheel 35 and fixedly connected to the top of the lifting mechanism 12. First electric cylinders 13 are symmetrically fixedly connected to the front and rear sides of the lifting mechanism 12. The movable end of the first electric cylinder 13... A movable seat 15 is fixedly connected to the common structure. First guide rods 14 are fixedly connected to the four corners of the movable seat 15. The first guide rods 14 slide through the lifting mechanism 12. A storage slot 16 is provided above the groove at the top of the movable seat 15. Second electric cylinders 17 are fixedly installed at both ends of the storage slot 16 inside the movable seat 15. The movable end of the second electric cylinder 17 passes through the top of the movable seat 15 and is fixedly connected to the storage slot 16. Connecting plates 21 are fixedly installed on both sides of the groove opening of the movable seat 15. A first scraper 19 and a second scraper 20 are fixedly installed from top to bottom at the front end of the connecting plate 21. The length of the first scraper 19 and the second scraper 20 is greater than the length of the movable seat 15. A limit mechanism is fixedly installed on the outside of the connecting plate 21. Second guide rods 18 are fixedly connected to both ends of the storage slot 16. The second guide rods 18 slide through the groove opened on the side wall of the connecting plate 21.

[0024] In use, the movable end of the third electric cylinder 33 pushes the top frame 9 against the roof under the guidance of the guide mechanism 7, thus fixing the device. By adjusting the length of the movable end of the limiting mechanism extending beyond the first scraper 19 and the second scraper 20, the movable end of the first electric cylinder 13 pushes the moving seat 15 to move, so that the end of the limiting mechanism is against the wall surface to be plastered, determining the distance between the first scraper 19 and the second scraper 20, and controlling the plaster thickness. The limiting mechanism is then adjusted back to its original state, and concrete mortar is applied into the storage tank 16, so that the concrete mortar is between the storage tank 16 and the wall surface. The winch 36 operates, winding the traction rope 8, which pulls the lifting mechanism 12, guided by the guide mechanism 7, upward. The moving seat 15, carrying the storage tank 16, the first scraper 19, and the second scraper 20, moves upward. The concrete mortar in the storage tank 16 flows towards the first scraper 19. The first scraper 19 and the second scraper 20 scrape the concrete mortar onto the wall. When the top of the storage tank 16 is in contact with the roof, the movable end of the second electric cylinder 17 moves the storage tank 16 downward, so that the storage tank 16 is built into the groove of the moving seat 15. The top of the first scraper 19 is in contact with the roof, so that the first scraper 19 applies the concrete mortar to the top of the wall. After the top of the first scraper 19 is in contact with the roof, the winch 36 rotates in the opposite direction, so that the lifting mechanism 12 moves downward. The first scraper 19 and the second scraper 20 follow and move downward, and the plastered wall surface is trimmed again.

[0025] The limiting mechanism includes a tube body 22, which is fixedly mounted on a connecting plate 21. A guide sleeve 26 is fixedly mounted on the side of the connecting plate 21 near the wall. A ruler 24 is provided inside the tube body 22. The end of the ruler 24 slides through the guide sleeve 26 and is fixedly connected to an end 23. The thickness of the end 23 is the same as the thickness of the first scraper 19 and the second scraper 20. One end of the ruler 24 inside the tube body 22 is fixedly connected to a guide block 28 that slides through the inner wall of the tube body 22. A screw 27 is rotatably connected inside the tube body 22. The screw 27 passes through the guide block 28 into the ruler 24 and is threadedly connected to the ruler 24. The end of the screw 27 passes through the end of the tube body 22 and is fixedly connected to a rotating cap 25. A slot 29 is provided at the bottom of the ruler 24. The guide sleeve 26 has a sliding locking block 30 inside the 29. The locking block 30 is fixedly connected to the inner wall of the guide sleeve 26. The outer side of the end 23 in its initial state is flush with the outer side of the first scraper 19 and the second scraper 20. In use, the screw 27 is rotated by rotating the cap 25. Rotating the screw 27 drives the ruler 24 to move under the guidance of the locking block 30 and the locking groove 29. The length of the end 23 extending out of the first scraper 19 and the second scraper 20 is adjusted by coordinating with the scale lines on the ruler 24. The movable end of the first electric cylinder 13 pushes the moving seat 15 to move, so that the end 23 is in contact with the plastered wall. The first electric cylinder 13 stops working. By rotating the rotating cap 25 in the opposite direction, the end 23 is retracted back to its original position, thereby limiting the plaster thickness and controlling the plaster thickness.

[0026] A cross brace 32 is fixedly installed between the guide mechanisms 7. The bottom of the cross brace 32 is fixedly connected to the top of the fixed end of the third electric cylinder 33. The movable end of the third electric cylinder 33 passes through the cross brace 32.
