Further, in order to ensure that the contact area of the contact end face is larger, the scraping effect of the contact end face is optimized, so that the opening end of the shield 31 can be bent towards the outside of the accommodating cavity and extends to form a section of wider contact end face, and the scraping effect of the contact end face is better.

Specifically, the cross-sectional area of the accommodating chamber in the direction perpendicular to the first axis gradually increases from the sealed end to the open end. The area of the opening end is larger, so that the plastering efficiency is improved; but also can form a streamline accommodating cavity, so that mortar in the accommodating cavity can be fully pushed to the plastering end. It is understood that the fan blades 322 located inside the accommodating cavity also expand along with the expansion of the accommodating cavity, so that the area of the pulp pushing surface also increases gradually.

Further, the cross section of the accommodating cavity in the direction perpendicular to the first axis is a circular surface, so that the accommodating cavity can be more matched with the rotating cross section of the plastering member 32, dead angles are avoided from being generated in the accommodating cavity, a large amount of residual mortar in the accommodating cavity is caused, and the plastering efficiency is affected.

The difference is that: the two scraping belts 323 are arranged, the two scraping belts 323 extend in a cross shape, the first axis is located at the junction of the two scraping belts 323, and compared with one scraping belt 323, the number of circular planes formed by rotation of the plastering end in the same time is more under the condition that smooth flow of mortar is not affected, the total contact area with a wall surface is increased, and plastering and scraping frequencies are higher; by arranging two strickle strips 323 to extend in a cross shape, the plastering piece 32 forms a circular plane when rotating by 90 degrees, and meanwhile, the plastering piece 32 is guaranteed to be stressed in balance during rotation, and the plastering effect is good.

Specifically, the plastering member 32 includes a supporting portion 321 and a blade 322, the supporting portion 321 is connected with the driving assembly 2, the blade 322 is disposed on an outer peripheral surface of the supporting portion 321, and the paste pushing surface is disposed on an outer surface of the blade 322. In this embodiment, four blades 322 are disposed, and the four blades 322 are disposed on the outer circumferential surface of the supporting portion 321 along the circumferential direction of the supporting portion 321 in a cross arrangement, each blade 322 has a plastering end, and the plastering ends of the two opposite blades 322 are located on a straight line to form a scraping belt 323.

The four fan blades 322 form two scraping belts 323, and the two scraping belts 323 are distributed in a cross shape.

In summary, the number of the scraping bands 323 is increased, so that the number of times of contact between the plastering end and the wall surface in the same time can be increased, so that the plastering frequency and the scraping frequency are higher, but at the same time, the number of plastering pieces 32 in the accommodating cavity is also required to be increased, and the mortar in the accommodating cavity is reduced. Therefore, the number of the shaving belt 323 is appropriately selected according to the site construction situation.
