[0028] A mortar inlet 5 is provided at the top of the mortar box 11. The shape and size of the mortar inlet 5 are also optimized according to the actual use.

[0029] A mortar pusher plate 15 is slidably installed inside the mortar box 11 to push mortar out of the mortar outlet 6. Two tie rods 3 are fixedly installed on the end face of the mortar pusher plate 15 away from the mortar outlet 6. The two tie rods 3 extend horizontally backward out of the mortar box 11 and are slidably engaged with the mortar box 11. Limit caps are fixedly installed on the ends of the two tie rods 3 away from the mortar pusher plate 15.

[0030] Two vertical baffles 18 are fixedly installed on the front side of the mortar box 11. The two baffles 18 are parallel to each other and symmetrically arranged with respect to the mortar outlet 6. The two baffles 18 slide in contact with the building wall surface, and the top ends of the two baffles 18 near the building wall surface are provided with rounded corners.

[0031] A plastering board 7 for plastering is fixedly installed between the two baffles 18, and the plastering board 7 is inclined. Specifically, the high end of the plastering board 7 is fixedly connected to the front end face of the mortar box 11, and the vertical distance from the low end of the plastering board 7 to the front end face of the mortar box 11 is less than the vertical distance from the front end face of the two baffles 18 to the front end face of the mortar box 11.

[0032] Two horizontal support shafts 4, perpendicular to the two baffles 18, are rotatably mounted on the opposite end faces of the two baffles 18. The two support shafts 4 are coaxially opposed. A rotating shaft 12, parallel to the two support shafts 4, is placed horizontally between the two baffles 18. The rotating shaft 12 passes through the plaster board 7 and the two baffles 18 and is rotatably connected to the plaster board 7 and the two baffles 18.

[0033] Two fixing plates 9 are fixedly installed on the mortar box 11, two baffles 18 are located between the two fixing plates 9, and the rotating shaft 12 passes through the two fixing plates 9 and is rotatably connected to the two fixing plates 9.

[0034] A roller 13 is detachably mounted on each of the two axial ends of the rotating shaft 12 and on each of the two support shafts 4 via a disassembly assembly. Each roller 13 rolls against the building wall surface, and each roller 13 is a rubber wheel.

[0035] Specifically, the assembly / disassembly component includes a locking nut 17. Threaded sections are provided on both axial ends of the rotating shaft 12 and the axial ends of the two support shafts 4 away from the baffle 18. A retaining ring is fixedly fitted on each of the two axial ends of the rotating shaft 12 and the axial ends of the two support shafts 4 away from the baffle 18. A locking nut 17 is threadedly connected to each threaded section. The roller 13 abuts against and fixes the locking nut 17 and the retaining ring.

[0036] A linkage mechanism is provided between the rotating shaft 12 and the mortar pusher plate 15 to drive the mortar pusher plate 15 to slide close to the mortar outlet 6. The rotating shaft 12 is connected to the mortar pusher plate 15 through the linkage mechanism.

[0037] Specifically, the linkage mechanism includes two wire pulleys 16, which are coaxially opposed and parallel to the rotating shaft 12. Two mounting slots for mounting the wire pulleys 16 are provided on the mortar box 11, and the two wire pulleys 16 are rotatably mounted in the mounting slots via axles.

[0038] The mortar pusher plate 15 is slidably disposed between two rollers 16. A pull rope 14 is fixedly disposed between each roller 16 and the end face of the mortar pusher plate 15 facing the mortar outlet 6. Each pull rope 14 is inserted into the side of the mortar box 11 where the mortar outlet 6 is opened and exits from the mortar box 11.

[0039] Each pull rope 14 is made of tensile and corrosion-resistant material.

[0040] Each pull rope 14 is in a side-limiting sliding engagement with the mortar outlet 6 of the mortar box 11. Specifically, the two pull ropes 14 are located inside the mortar box 11, with the rope body perpendicular to the mortar push plate 15.

[0041] Each of the two reels 16 is connected to the rotating shaft 12 via a transmission component.

[0042] Specifically, the transmission components include a first gear 8 and a second gear 10. The first gear 8 is fixedly sleeved on the rotating shaft 12, and the second gear 10 is coaxially and fixedly connected to the axle of the reel 16. The first gear 8 and the second gear 10 are meshed together.

[0043] The first gear 8 is a small gear, and the second gear 10 is a large gear. The transmission ratio between the two is greater than one.

[0044] Working principle: When using this device to plaster building walls, mortar is added from the mortar inlet 5 into the mortar box 11. Next, the worker uses the telescopic rod 1 to position the side of the mortar box 11 with the mortar outlet 6 facing the building wall, ultimately bringing the four rollers 13 into contact with the wall. Then, pressing down on the mortar box 11 causes pressure to be transmitted to the four rollers 13 via two baffles 18. These baffles, through a rotating shaft 12 and two support shafts 4, deform the rollers, causing the two baffles 18 to contact and abut against the building wall.

[0045] Next, the worker pushes the mortar box 11, which is driven by two baffles 18. These baffles, via a rotating shaft 12 and two support shafts 4, drive four rollers 13 to rotate. Simultaneously, the rotating shaft 12 rotates with the rollers 13, causing its first gear 8 to rotate. The first gear 8 drives the corresponding second gear 10 to rotate, which in turn drives its axle to rotate. This axle then drives its threaded reel 16 to rotate. At this point, the two threaded reels 16 simultaneously wind up their respective pull ropes 14, which in turn pull the mortar pusher 15, pushing the mortar from the mortar box 11 out of the mortar outlet 6. The pushed-out mortar is then applied to the building wall by the plastering slab 7.

[0046] After all the mortar in the mortar box 11 has been pushed out, the worker pulls the two levers 3. The levers 3 pull the mortar pusher plate 15 away from the mortar outlet 6. Simultaneously, the mortar pusher plate 15 pulls the two ropes 14, releasing them from their respective reels 16 until they are completely released. Then, mortar is refilled into the mortar box 11, and the plastering operation continues. It should be noted that after use, this device needs to be cleaned with cleaning solution promptly to prevent mortar from solidifying on the mortar box 11 and the ropes 14.

[0047] To prevent the pull rope 14 from forming a knot, a torsion spring can be fitted on the axle, so that one end of the torsion spring is fixed to the pulley 16 and the other end is fixed to the mortar box 11, thereby ensuring that the pull rope 14 is always taut.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
