[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] Please see Figure 1-3 This utility model provides a technical solution for an indoor wall plastering device:

[0030] Example 1:

[0031] according to Figure 1-3 As shown, it includes a vertical cylinder 1, a lifting assembly, a connecting assembly, a sliding sleeve 21, and a collection trough 32. A base 13 is fixedly installed at the bottom of the vertical cylinder 1. The base 13 is T-shaped to increase the contact area with the ground and improve the stability of the vertical cylinder 1. The sliding sleeve 21 is fitted on the outer side of the vertical cylinder 1.

[0032] A connecting plate 22 is fixedly installed on one side of the sliding sleeve 21. A vertical groove 11 is opened on the side of the vertical cylinder 1 away from the connecting plate 22 to prevent mortar in the collection trough 32 from falling into the groove 11. The lifting assembly includes a threaded rod 24, a drive motor 27, and a slider 26. Bearings are respectively fitted on the upper and lower ends of the threaded rod 24. The two bearings are respectively installed on the top and bottom of the vertical cylinder 1. The drive motor 27 is fixedly installed on the top of the vertical cylinder 1, and its output shaft is connected to the upper end of the threaded rod 24. A nut 25 is threadedly connected to the threaded rod 24. The slider 26 is set in the groove 11, and its two ends are fixedly connected to the nut 25 and the inner side of the sliding sleeve 21, respectively. The drive motor 27 drives the threaded rod 24 to rotate. By utilizing the threaded connection between the nut 25 and the threaded rod 24 and the cooperation of the slider 26 in the groove 11, the sliding sleeve 21 is driven to slide up and down along the vertical cylinder 1.

[0033] One end of the connecting plate 22 has a through hole, and at least one arc-shaped support plate 31 is installed at its bottom. In this embodiment, there are two arc-shaped support plates 31. The arc-shaped support plates 31 are set away from the through hole. The collection tank 32 has a groove for collecting mortar, and its two ends are open. A pin 61 is fixedly installed on the side of the collection tank 32 near the connecting plate 22. The open end of the pin 61 passes through the through hole, and a stop bar 62 is inserted into the open hole. By setting the pin 61, on the one hand, the collection tank 32 is supported by the connection of the pin 61. On the other hand, when it is necessary to clean the mortar in the collection tank 32, one end of the collection tank 32 can be lifted up while the other end is tilted down, so that the mortar in the collection tank 32 can be poured out quickly, which greatly improves the cleaning efficiency and reduces the labor intensity of workers.

[0034] The bottom of the collection trough 32 contacts the arc-shaped support plate 31, allowing the arc-shaped support plate 31 to support the collection trough 32. The connecting assembly includes a connecting ear plate 51 and a fixing ear plate 52. The fixing ear plate 52 is welded and fixed to the bottom of the arc-shaped support plate 31, and the connecting ear plate 51 is welded and fixed to the bottom of the collection trough 32. The connecting ear plate 51 and the fixing ear plate 52 are connected by bolts 53. Under the connection of the bolts 53, the collection trough 32 is stably placed on the arc-shaped support plate 31, ensuring the stability of the collection trough during use. Furthermore, by removing the bolts 53 and separating the stop bar 62 from the pin 61, the collection trough 32 can be removed, making it easier for workers to carry the collection trough 32 and the vertical cylinder 1 separately, greatly facilitating the transportation and carrying of the device.

[0035] A plastering rod 33 is fixedly installed on the side of the collection trough 32 away from the connecting plate 22. The threaded rod 24 is driven to rotate by the drive motor 27. The sliding sleeve 21 can be driven to slide up and down along the vertical cylinder 1 by the threaded connection between the nut 25 and the threaded rod 24 and the cooperation of the slider 26 in the sliding groove 11, thereby driving the plastering rod 33 to perform plastering work on the wall.

[0036] The collection tank 32 is equipped with a scraper 4 for scraping mortar. The shape of the scraper 4 is adapted to the groove of the collection tank, and a hand hole is provided at the upper end of the scraper 4 to facilitate workers to use the scraper 4 to clean the mortar remaining in the collection tank 32.

[0037] In practical use, the indoor wall plastering device of this utility model is first moved to the construction area and the plastering rod 33 is brought into contact with the mortar on the wall. At the same time, the stability of the base 13 is ensured (a counterweight can be placed on the base 13, or the worker can step on the base 13 to improve the stability of the vertical cylinder 1 during use).

[0038] Start the drive motor 27, which drives the threaded rod 24 to rotate in the forward direction. Utilize the threaded connection between the nut 25 and the threaded rod 24 and the cooperation of the slider 26 in the slide groove 11 to drive the sliding sleeve 21 to slide upward along the vertical cylinder 1. During the movement, the sliding sleeve 21 drives the collection trough 32 and the plastering rod 33 to move upward, so that the plastering rod 33 can perform plastering work on the wall surface, and the scraped mortar falls into the collection trough 32.

[0039] After plastering a section of the wall is completed, move the device away from the wall by moving the plastering rod 33 away from the wall and control the reverse rotation of the drive motor 27 to lower the collection tank 32 to a suitable height. Then remove the bolt 53. Under the hinge action of the pin 61, one end of the collection tank 32 near the arc-shaped support plate 31 can be lifted upward while the other end is tilted downward, so that the mortar in the collection tank 32 can be poured out quickly. After the mortar is poured out, the worker uses the scraper 4 to clean the mortar remaining in the collection tank 32.

[0040] Finally, the collection trough 32 is placed on the arc-shaped support plate 31, and the connecting ear plate 51 and the fixing ear plate 52 are connected using bolts 53. The device is then moved to the next location where plastering is required.

[0041] Example 2:
