[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0034] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0035] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0036] like Figure 1 and Figure 2 As shown, in the first aspect, the present application provides a plastering assembly, including: a plastering mechanism 10, a displacement mechanism 20 and a recovery box 30, the plastering mechanism 10 includes a connected trowel plate 11 and a protective plate 12, a mortar passage 13 is formed between the trowel plate 11 and the protective plate 12; the displacement mechanism 20 includes a supporting platform 21 and a side baffle plate 22, the trowel plate 11 is connected to the supporting platform 21 at an angle, and a mortar channel 23 is formed between the side baffle plate 22 and the protective plate 12, the mortar passage 13 is connected to the mortar channel 23; the recovery box 30 is connected to the mortar channel 23 at one end away from the mortar passage 13.

[0037] By forming a mortar passage 13 for the lime slurry to pass through on one side of the trowel plate 11, the lime slurry can enter the mortar channel 23 and finally enter the recovery box 30, thereby realizing direct recovery of the lime slurry without the need to recover it during the plastering construction process. This not only does not affect the plastering effect, but also directly reduces the process of cleaning and recovering excess lime slurry, effectively improving the efficiency of the plastering construction. The present application effectively solves the problem that excessive lime slurry causes lime slurry to escape from both sides of the trowel plate, affecting the quality of the plastering and increasing the cleaning and recovery process.

[0038] It should be noted that during the plastering process, the lime slurry flows out from the side of the trowel plate 11 facing the working wall and adheres to the working wall. Due to the fluidity of the lime slurry, part of the lime slurry will slide out from both sides of the trowel plate 11 after flowing out, resulting in unevenness of the working wall and falling off. Manual cleaning and recycling operations are time-consuming and labor-intensive, and will also leave marks on the wall, affecting the visual appearance. Therefore, a direct recycling method is adopted, which can complete the recycling of excess lime slurry in one construction, without consuming additional manpower and material resources, thereby improving construction efficiency and meeting the requirements for the appearance of the working wall.

[0039] Furthermore, in some embodiments of the present application, the trowel plate 11, the protective plate 12 and the recovery box 30 are each provided in two pieces, which are arranged on both sides of the working surface of the trowel plate 11, respectively, so that the recovery position is more comprehensive.

[0040] In some optional embodiments, when the plastering has a pattern, the pattern can be formed by adding a mortar channel 23 on the working side of the trowel plate 11.

[0041] In some optional embodiments, a limit plate can be further provided under the supporting platform 21 of the displacement mechanism 20 to form a second channel parallel to the mortar channel 23. A recovery box 30 is also provided at the end of the second channel. This can prevent the recovery box 30 from being unable to be further recovered after being full. At the same time, it can adapt to the working wall surface to avoid excessive escape of lime slurry.

[0042] like Figures 1 to 3 As shown, in some embodiments of the present application, the plastering assembly further includes a base 40, the displacement mechanism 20 further includes a moving seat 24, the moving seat 24 is movably connected to the base 40, the carrying platform 21 is fixedly connected to the moving seat 24, and the moving seat 24 is provided with a guide surface 241 adapted to the trowel plate 11. The movable connection between the moving seat 24 and the base 40 enables the movement of the trowel plate 11 and the troweling action. The setting of the guide surface 241 is used to add lime slurry, keep the lime slurry in the plastering assembly to meet the requirements of plastering, make full use of the area connected to the trowel plate 11, and facilitate the filling of materials during the construction process.

[0043] It should be noted that the guide surface 241 can be a curved surface or a flat surface, and its end can be tangent to or flush with the trowel plate 11, so that no lime slurry will remain between the two, which is convenient for plastering. The width of the guide surface 241 can be less than or equal to the width of the trowel plate 11. Such a setting can provide a buffer when the lime slurry flows to the trowel plate, does not increase the speed of the lime slurry flowing to the working wall surface, and reduces the impact on the quality of plastering.

[0044] like Figures 1 to 3 as well as Figure 5As shown, in some embodiments of the present application, a guide structure 41 is provided on the base 40, and the displacement mechanism 20 includes a driving structure 25, which is arranged on a side of the moving seat 24 away from the guide surface 241, and the driving structure 25 cooperates with the guiding structure 41 to drive the moving seat 24 to move. The setting of the guiding structure 41 is used to limit the moving direction of the moving seat 24 driven by the driving structure 25, so that the trowel plate 11 can move in a precise direction to achieve accurate plastering.

[0045] It should be noted that the driving structure 25 is arranged on a side of the moving seat 24 away from the guide surface 241, so that the structure is compact and separated from the lime slurry without affecting each other.

[0046] like Figures 1 to 5 As shown, in some embodiments of the present application, the guide structure 41 includes a rack 411, and the driving structure 25 includes a driving motor 251, a driving shaft 252 and a driving gear 253. The output end of the driving motor 251 is used to drive the driving shaft 252 to rotate, and the driving gear 253 is fixedly connected to the driving shaft 252, and the driving gear 253 is meshed with the rack 411. With the above-mentioned driving method, the transmission is intuitive, the structure is compact, and the lifting function can be effectively realized. The cooperation of the rack 411 and the driving gear 253 can realize precise lifting and lowering, and can also form an interlocking state to keep it in a fixed state, so as to facilitate the stable state when adding lime slurry.

[0047] It should be noted that if Figure 5 As shown, in some optional embodiments, the drive shaft 252 can be multi-section, and adjacent drive shafts 252 are fixedly connected by drive sleeves 254 to achieve transmission.

[0048] In order to facilitate the load-bearing platform 21 to achieve more stable displacement, multiple sets of racks 411 and driving gears 253 can be provided, for example, two sets of racks 411 and driving gears 253 are arranged on opposite sides of the driving shaft 252, and lifting is achieved through synchronous rotation and meshing of racks and gears. Alternatively, more sets of racks 411 and driving gears 253 can be used to achieve joint lifting at multiple positions and dispersed load bearing.

[0049] like Figures 1 to 6 As shown, in some embodiments of the present application, there are multiple racks 411, and the driving gear 253 is meshed with one of the racks 411. The multiple racks 411 are arranged to facilitate the selection of corresponding tooth shapes for matching with driving gears 253 of different sizes. Such an arrangement can meet the detachable interchangeability between the displacement mechanism 20 and the base 40, increase the interchangeability, and improve the overall flexibility of the plastering assembly.

[0050] like Figures 1 to 6As shown, in some embodiments of the present application, the driving motor 251 and the driving shaft 252 are connected via a gear transmission, or the driving motor 251 and the driving shaft 252 are connected via a worm gear transmission.

[0051] The gear meshing transmission method can achieve precise transmission control, and the gears can self-lock with each other, increasing the accuracy of the plastering process.

[0052] The worm gear transmission connection can satisfy the vertical arrangement of the motor to change the direction of power, so as to meet the output conditions. At the same time, the motor can be arranged more conveniently, clean up the space, and improve the assembly. The worm gear transmission method can also form a self-locking.

[0053] In an optional embodiment, a helical gear is provided at the output end of the driving motor 251, and a rotating gear is integrated on the driving shaft 252, so that transmission can be completed between the two and self-locking can be formed. In addition, by limiting the two ends of the driving shaft 252 along the axial direction, the driving shaft 252 can be driven to rotate only, and no deviation in the axial direction will occur.

[0054] like Figures 1 to 5 As shown, in some embodiments of the present application, the guide structure 41 further includes a guide groove 412, and the movable seat 24 is provided with a slider 242, and the slider 242 is slidably disposed in the guide groove 412. The setting of the guide groove 412 is used to adapt the slider 242 to limit the circumferential freedom of the displacement mechanism 20, so that the guide structure 41 can limit the sliding direction of the displacement mechanism 20 and achieve precise plastering.

[0055] Furthermore, if Figures 1 to 5 As shown, in some embodiments of the present application, a plurality of guide grooves 412 are provided, and are respectively provided on different surfaces of the guide structure 41, and the slider 242 is provided in one-to-one correspondence with the plurality of guide grooves 412. The provision of multiple groups of guide grooves 412 and sliders 242 can form restrictions at multiple positions, thereby making the restriction of the circumferential degree of freedom more accurate and reliable.

[0056] It should be noted that, in a specific embodiment, the movable seat 24 is generally in the shape of an "I" character, and the sliders 242 are respectively arranged inside the cavities on both sides of the "I" character and are arranged relative to each other. In this way, the movable seat 24 can clamp the column guide structure 41 from both sides, and the fit is higher.

[0057] The coordination between different racks 411 and the driving gear 253 can be achieved according to the coordination position between the slider 242 and the guide groove 412, that is, by adjusting the position of the slider 242, the meshing relationship between the driving gear 253 and different racks 411 is changed, thereby changing the rack 411 actually involved in the transmission.

[0058] like Figure 4 As shown, in the technical solution of this embodiment, the recovery box 30 is detachably connected to the movable seat 24 and the side baffle 22. Such an arrangement allows the recovery box 30 to be disassembled and replaced so as to recycle the lime slurry inside it after it is filled.

[0059] Specifically, the movable seat 24 and the side baffle 22 are respectively provided with a slide groove, which is a non-through groove and has a limit structure at the bottom. The recovery box 30 is provided with a plurality of strip structures at the position corresponding to the slide groove, and the strip structures are slidably matched in the slide groove to realize the detachable function. Such a structure is convenient and can be better disassembled and assembled.

[0060] It should be noted that in some optional embodiments of the present application, the bottom of the base 40 can be connected to a horizontal displacement mechanism to meet the horizontal position adjustment of the entire plastering assembly, thereby realizing the automation of the plastering assembly and further reducing the labor input.

[0061] like Figures 1 to 6 In some optional embodiments of the present application, a plastering assembly for use in construction engineering is provided, including a base 40, one side of the base 40 is threadedly connected to two guide structures 41, two racks 411 arranged opposite to each other are provided inside the guide structure 41, a groove body for the driving gear 253 to move is formed between the two racks 411, and guide grooves 412 are provided on two opposite outer sides of the guide structure 41;

[0062] The moving seat 24 of the displacement mechanism 20 is provided with a slider 242 corresponding to the guide groove 412, and a guide surface 241 is fixedly provided on the moving seat 24. The guide surface 241 can be a separate plate, and its shape is a curved plate or a straight plate. The plastering plate 11 of the plastering mechanism 10 is fixedly connected to the guide surface 241 by welding, and two protective plates 12 are fixedly provided on opposite sides of the plastering plate 11 by welding. The plastering plate 11 is fixedly installed on the bearing platform 21, and side baffles 22 are provided on both sides of the bearing platform 21. A mortar channel 23 is formed between the protective plate 12 and the side baffles 22. A recovery box 30 is inserted at the end of the mortar channel 23, and a handle for easy disassembly is fixedly provided on one side of the recovery box 30.

[0063] The bottom of the mobile seat 24 is provided with a driving structure 25, which includes a driving motor 251, a driving shaft 252, a driving gear 253 and a driving sleeve 254. The driving sleeve 254 is used to connect two adjacent driving shafts 252. The surface of the driving shaft 252 is integrated with a transmission tooth adapted to the output end of the driving motor 251. The output end of the driving motor 251 is provided with an adapted helical gear, and the transmission is realized by the rotation of the driving motor 251. The driving shaft 252 transmits the rotational power to the driving gear 253, and the driving gear 253 cooperates with the rack 411 to realize the lifting and lowering of the mobile seat 24 as a whole. Such a setting is convenient for applying lime slurry to the set position according to the actual need of plastering the wall.

[0064] It should be noted that the two sides of the trowel plate 11 collect the excess lime slurry and concentrate it in the recovery box 30, which is convenient for the user to recycle the lime slurry or introduce it into the guide surface 241 for secondary utilization, and the staff can better collect and process the fallen lime slurry.

[0065] Furthermore, in the technical solution of this embodiment, the number of the driving gears 253 used for lifting is set to two, which can cooperate with the driving shaft 252 to lift and lower the position height in the groove body between the two racks 411.

[0066] The recovery box 30 is symmetrically distributed with the driving shaft 252 as the center, the driving shaft sleeve 254 is symmetrically distributed with the moving seat 24 as the center, and the driving shaft 252 is set at the bottom of the moving seat 24.

[0067] The recovery boxes 30 are symmetrically distributed with the moving seat 24 as the center, and the guide structures 41 are symmetrically distributed with the carrying platform 21 as the center.

[0068] The number of the recovery boxes 30 is set to two, which can cooperate with the guide surfaces 241 at both ends to transport the materials.

[0069] The guide grooves 412 are symmetrically distributed with the guide structure 41 as the center, and the slider 242 of the moving seat 24 is slidably connected inside the guide grooves 412 .

[0070] The number of the guide grooves 412 is set to two, which can cooperate with the slider 242 to drive the carrying platform 21 to slide.

[0071] The implementation principle of a plastering assembly for construction engineering in the above embodiment is as follows: place the device in a suitable position, adjust the horizontal position through the driving device connected to the base 42 of the base 40, and then drive the transmission gear integrated on the surface of the driving shaft 252 through the driving motor 251 in cooperation with the bevel gear, thereby driving the driving gear 253 to rotate, and the driving gear 253 cooperates with the rack to lift or lower the mobile seat 24 connected to it, so as to realize the application of lime slurry. During the application process, the excess lime slurry enters the slurry channel 23 from both sides of the plastering plate 11, and then enters the recovery box 30, which is convenient for the staff to collect and process the fallen lime. During this period, the staff can disassemble the recovery box at any time and pour the lime slurry into the guide surface 241 or recycle it.

[0072] In a second aspect, some embodiments of the present application further provide a plastering device, the plastering device comprising a plastering assembly as in any of the above embodiments.
