Please note that, in order to clearly demonstrate the structure of the components in the embodiments of the invention, the drawings are not drawn to the same scale. The same reference numerals are used to indicate the same parts.

[0024] The principles and features of the present invention are described below with reference to the accompanying drawings. The embodiments described are for illustrative purposes only and are not intended to limit the scope of the invention. The following description, in conjunction with... Figure 1-9 The preferred embodiments of the present invention will be described in further detail below: Example 1: Depend on Figure 1-2 It is known that an indoor plastering machine for building construction includes a support structure 1 and an adjustment structure 2. The adjustment structure 2 is set on the upper part of the support structure 1, so that the support structure 1 can slide laterally.

[0025] The support structure 1 includes a base 101 and a lifting assembly 102. The base 101 is a box with openings at the top and bottom. The lifting assembly 102 is mounted on the base 101. The lifting assembly 102 includes a lifting rod 1021, a support frame 1022, a connecting plate 1023, and a top plate 1024. The support frame 1022 consists of two symmetrically arranged uprights. The support frame 1022 is vertically fixed on the base 101. The connecting plate 1023 is horizontally arranged between the support frames 1022 and is fixedly connected to the support frames 1022. The lifting rod 1021 is vertically arranged in the middle of the connecting plate 1023, and the bottom end of the lifting rod 1021 is connected to the base 101. The top telescopic end is connected to the top plate 1024. A plastering device is installed on the top plate 1024 to plaster the wall. By setting the lifting rod 1021 and the top plate 1024, the lifting rod 1021 can push the top plate 1024 upward to change the position of the plastering device.

[0026] Depend on Figure 3-5It can be seen that the adjustment structure 2 includes a rotating component 201, a first adjustment component 202, and a second adjustment component 203. The rotating component 201 is fixedly disposed on the side of the connecting plate 1023. The first adjustment components 202 are arranged in pairs, symmetrically disposed at both ends of the rotating component 201. The second adjustment components 203 are arranged in pairs, with the two second adjustment components 203 respectively disposed at the outer ends of the two first adjustment components 202. The rotating component 201 includes a rectangular groove 2011 and a first motor 201. 2. A connecting shaft 2013, a gear 2014, a first gear plate 2015, and a fixing frame 2017 are included. A rectangular groove 2011 is fixedly mounted on a connecting plate 1023 and can move up and down with the connecting plate 1023. The fixing frame 2017 is located inside the rectangular groove 2011 and is slidably connected to the rectangular groove 2011. The connecting shaft 2013 is located on the upper part of the fixing frame 2017, and both ends of the connecting shaft 2013 are rotatably connected to the side walls of the rectangular groove 2011. A first motor 2012 is located in the rectangular groove 2011. On the side, the first motors 2012 are arranged in pairs, and a fixing block is fixedly installed on the side of each first motor 2012. The fixing block can fix the first motor 2012, making its operation more stable. The output shaft of each first motor 2012 is connected to a connecting shaft 2013. Two gears 2014 are sleeved on the left connecting shaft 2013, and one gear 2014 is sleeved on the right connecting shaft 2013. The three gears 2014 are arranged alternately. The first gear plate 2015 is provided with... Three first toothed plates 2015 are spaced apart within the fixed frame 2017, and each of the three first toothed plates 2015 meshes with a gear 2014. Specifically, the two gears 2014 on the left connecting shaft 2013 mesh with the two outer first toothed plates 2015, and the gear 2014 on the right connecting shaft 2013 meshes with the middle toothed plate. A connecting frame 2016 is provided at the end of the fixed frame 2017, and the connecting frame 2016 has bolt holes for easy connection with the first adjusting assembly 202.

[0027] The first adjustment component 202 includes a first adjustment frame 2021 and a second toothed plate 2022. The first adjustment frame 2021 has connecting holes 2023 at both ends. The connecting holes 2023 are threaded and connected to the bolt holes on the connecting frame 2016 by bolts, so that the first adjustment frame 2021 is connected to the fixed frame 2017. Three second toothed plates 2022 are spaced apart. The three second toothed plates 2022 are all fixedly installed in the first adjustment frame 2021 and respectively connect with the three first toothed plates 2015. Multiple first adjustment components 202 can be provided. Multiple first adjustment components 202 are connected by bolts in adjacent connecting holes 2023. The contact surface of the fixed frame 2017 and the first adjustment frame 2021 is the same size. The rectangular groove 2011 slides along the fixed frame 2017 and the first adjustment frame 2021.

[0028] The second adjustment assembly 203 includes a second adjustment frame 2031, a first threaded shaft 2032, a positioning shaft 2033, and a rotating plate 2034. The second adjustment frame 2031 consists of two parallel adjustment plates, which are fixedly connected by a connecting rod. The first threaded shaft 2032 passes through the two adjustment plates, with one end fixedly connected to the adjustment plate on the side away from the first adjustment assembly 202, and the other end threadedly connected to the connecting hole 2023 of the first adjustment frame 2021. The rotating plate 2034 is disposed between the two adjustment plates and sleeved on the first threaded shaft 2032. One end of the positioning shaft 2033 is disposed on the adjustment plate on the side closer to the first adjustment assembly 202 and is parallel to the first threaded shaft 2032. The other end of the positioning shaft 2033 is fixedly connected inside the first adjustment frame 2021. By setting the positioning shaft 2033, the adjustment plates can be limited to prevent rotation.

[0029] When this equipment is needed, the support structure 1 is moved to a suitable position, and the lifting rod 1021 is controlled to operate. The operation of the lifting rod 1021 can push the top plate 1024 upward to the position where plastering is required, thereby determining the position of the plastering equipment. Then, multiple sections of the first adjustment assembly 202 are prepared, and the connecting holes 2023 on the first adjustment assembly 202 are connected end to end and fastened with bolts to form a group of first adjustment assemblies 202. Finally, one end of the group of first adjustment assemblies 202 is fastened to the connecting frame 2016 on the fixed frame 2017 with bolts, and the other end is fastened to the first threaded shaft 2032 on the second adjustment assembly 203. Then, rotational power can be applied to the rotating plate 2034, causing the rotating plate 2034 and the first threaded shaft 2032 to rotate. When the first threaded shaft 2032 rotates, it will use the threaded connection with the first adjustment frame 2021 to drive the second adjustment frame 2031 to move towards the wall. The second adjustment frame 2031 is rotatably connected to the first threaded shaft 2032. The surface of shaft 2032 is such that the second adjusting frame 2031 cannot rotate under the action of positioning shaft 2033. This allows the first adjusting frame 2021 to move only laterally without rotating until the second adjusting frame 2031 is in close contact with the wall. When the plastering equipment needs to move laterally, the two first motors 2012 connected to the right connecting shaft 2013 are controlled to run. The operation of the two first motors 2012 will drive the gear 2014 to rotate. Utilizing the meshing relationship between the gear 2014 and the first toothed plate 2015, the rectangular groove 2011 and the support structure 1 can be driven to slide on the first adjusting frame 2021. After sliding to the designated position, plastering work can be carried out. At this time, the two first motors 2012 connected to the left connecting shaft 2013 are in a stopped state. When the support structure 1 slides to the edge of the wall, the two first motors 2012 connected to the left connecting shaft 2013 are controlled to run, causing the two first motors 2012 connected to the right connecting shaft 2013 to stop. This completes the plastering work of the entire wall.

[0030] Example 2: Based on Embodiment 1, a collection structure 3 is also provided. The collection structure 3 is located at the lower part of the support structure 1 to collect and treat the slurry that falls and accumulates during plastering work. Figure 6-9It is known that the collecting structure 3 includes a collecting component 301, a transmission component 302, and a discharging component 303. The collecting component 301 is located at the rear of the base 101, and the discharging component 303 is located at the front of the base 101. The transmission component 302 connects the collecting component 301 to the base 101. The collecting component 301 includes a smearing plate 3011, a scraper 3012, and a first hydraulic rod 3013. The smearing plate 3011 is vertically located at the rear of the base 101. The scraper 3012 is slidably located at both ends of the smearing plate 3011 and is perpendicular to the front side of the smearing plate 3011. The first hydraulic rod 3013 is located on the smearing plate 3011, and the telescopic end of the first hydraulic rod 3013 is connected to the scraper 3012. A collecting plate is provided at the bottom of the smearing plate 3011. One end of the collecting plate is fixedly connected to the bottom end of the smearing plate 3011, and the other end is connected to the base 101, so that the collecting plate can transport the collected plaster into the base 101.

[0031] The transmission assembly 302 includes a positioning plate 3021, a second threaded shaft 3022, a long shaft 3023, a second motor 3024, a fixing plate 3025, and a transmission block 3026. The positioning plate 3021 is disposed on the rear side wall of the base 101, and the positioning plate 3021 and the smoothing plate 3011 are connected by the second threaded shaft 3022. The second motor 3024 is disposed on the front side wall of the base 101. The long shaft 3023 is disposed inside the base 101, one end of the long shaft 3023 is connected to the second motor 3024, and the other end is fixedly connected to the transmission block 3026. The transmission block 3026 is disposed on the second threaded shaft. The inner cavity of 3022 has two first sliding grooves symmetrically arranged on the side wall of the rear part of the base 101. Each first sliding groove is slidably connected to a first slider. The cross-section of the first sliding groove and the first slider is T-shaped. The bottom of the first slider is fixedly set on the squeegee plate 3011. The first slider slides in the first sliding groove, which can limit the squeegee plate 3011, so that the squeegee plate 3011 can move laterally while following the lifting component 102 to rise and fall. A telescopic hose is also provided between the positioning plate 3021 and the squeegee plate 3011. The telescopic hose is connected to the positioning plate 3021 and the squeegee plate 3011.

[0032] The unloading assembly 303 includes a second hydraulic rod 3031, casters 3032, and a base plate 3033. The second hydraulic rod 3031 is vertically fixed on the side walls at the four corners of the base 101. The casters 3032 are located at the bottom of the second hydraulic rod 3031 and connected to the telescopic end of the second hydraulic rod 3031. An installation sleeve is provided on the outside of the second hydraulic rod 3031. The outside of the installation sleeve is fixed to the side wall of the base 101, and the inside of the installation sleeve is fixed to the rod wall of the second hydraulic rod 3031. The base plate 3033 is located at the bottom of the base 101. Second sliding grooves are provided at the bottom of the left and right side walls of the base 101. The base plate 3033 is provided with a second slider. The cross-section of the second sliding groove and the second slider is T-shaped, allowing the second slider to slide within the second sliding groove. A handle is provided at the front of the base plate 3033. By setting up the unloading unit, the collected mortar can be centrally unloaded. By setting up the adjustment structure 2 and the collection structure 3, the problem of reduced construction efficiency due to equipment defects during use can be effectively avoided.

[0033] When the equipment is plastering, the second hydraulic rod 3031 is retracted, causing the base plate 3033 to contact the ground. Workers use shovels to pile mortar into the plastering equipment, and then the lifting assembly 102 is moved upwards to complete the plastering work. During plastering, mortar may fall onto the wall. At this time, the first hydraulic rod 3013 is activated, pushing the two scrapers 3012 to unfold. The unfolded scrapers 3012 cover the nearby fallen mortar until the lifting assembly 102 descends to a position in contact with the ground. The positioning plate 3021 is fixed to the base 101. The positioning plate 3021 and the second threaded shaft 3022 rise with the unloading assembly 303. When the unloading assembly 303 descends to a position in contact with the ground... When in position, the transmission block 3026 will be at the opening of the positioning plate 3021 and the second threaded shaft 3022. At this time, the second motor 3024 can drive the transmission block 3026 through the long shaft 3023, and then drive the second threaded shaft 3022 to rotate. By utilizing the threaded connection between the second threaded shaft 3022 and the trowel plate 3011, the trowel plate 3011 can be driven to slide. During the sliding process of the trowel plate 3011, the first hydraulic rod 3013 will gradually return to its original position, causing the mortar on both sides to move towards the middle, until the trowel plate 3011 pushes the mortar into the space between the bottom plate 3033 and the base 101. The presence of the telescopic hose can ensure that the mortar will not affect the threaded connection between the second threaded shaft 3022 and the trowel plate 3011.

[0034] Once the plastering work on one wall is completed, the operator can first use the equipment's movement function to smoothly transfer the support structure 1 to an open area within the construction site free of obstacles, ensuring that there are no construction materials piled up or personnel lingering nearby, leaving sufficient space for subsequent mortar cleaning work. After reaching the designated position, the operator manually grasps the handle at the front end of the unloading component 303, causing the base plate 3033 to smoothly slide outward along the second sliding groove on the side wall of the base 101, thus removing the bottom support from the residual mortar collected inside the base 101. Then, the second hydraulic rod 3031 is activated to extend and retract. The end extends upwards synchronously, steadily pushing the plastering machine upwards until a sufficient gap is formed between the bottom of the support structure 1 and the ground, ensuring that the internal mortar can fall smoothly without residue. As the support structure 1 moves upwards, the residual mortar collected inside will naturally fall from the bottom opening to the open ground below under the action of gravity, forming a concentrated pile of mortar. Through this series of continuous operations, the cleaning and centralized collection of residual mortar can be completed quickly without the need for additional cleaning tools, which simplifies the work process, reduces mortar waste, and improves the cleanliness and efficiency of the construction site.
