Description

Technical Field

[0001] This invention relates to the field of building plastering equipment technology, and in particular to a building plastering method and plastering device. Background Technology

[0002] Plastering, in the construction industry, generally refers to the process of applying materials such as lime mortar, mixed mortar, polymer water mortar, hemp fiber mortar, paper fiber mortar, and thermal insulation mortar granules to the surface of a building. A good plastering process can make the building surface smoother, increase the building's aesthetics, and improve the building's sound insulation, heat insulation, and other properties.

[0003] Traditional building plastering work mainly relies on manual operation. Manual plastering is not only labor-intensive, but also inefficient and produces poor plastering quality.

[0004] Current plastering equipment cannot perform double-layer plastering, which affects plastering efficiency and is not conducive to improving plastering effect. Furthermore, it cannot quickly and automatically seal the discharge port after plastering, causing slurry to leak outside the discharge port, which may result in additional plastering areas and affect plastering quality. When slurry falls along the discharge port, it reduces environmental cleanliness. Long-term accumulation of slurry outside the discharge port will form residual solid dirt, which is not easy to clean and occupies the effective plastering area. Summary of the Invention

[0005] This invention provides a method and device for plastering buildings. After plastering is completed, the outlet can be quickly and automatically sealed to prevent slurry from leaking outside the outlet. It automatically achieves double-layer plastering treatment of slurry to a predetermined height, saving manpower, improving plastering efficiency, avoiding long-term accumulation of slurry outside the outlet, reducing the formation of residual solid dirt, facilitating cleaning, and preventing the occupation of the effective plastering area.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] Furthermore, the outer end of the plastering bucket is connected to a feeding pump, the feeding pump is equipped with a feeding pipe, the inner side of the plastering bucket is equipped with a protective cover, the protective cover divides the plastering bucket into two outer material areas and an inner material area, the protective cover is provided with a material hole, the inner end of the elastic component is connected to the side of the protective cover near the discharge port, the plug is horizontally slidably connected to the protective cover, the inner side of the outer material area is provided with a confluence plate, the top of the confluence plate is inclined towards the protective cover, and the top of the confluence plate is higher than the material hole.

[0009] Furthermore, the protective cover has a sliding cavity on the side near the discharge port, and a partition is slidably fitted inside the sliding cavity. The inner side of the partition is connected to the elastic component, and the inner end of the plug is connected to the outer side of the partition. Through the partition, the slurry for the column blocking extends into the elastic component, extending the service life of the elastic component.

[0010] Furthermore, the translation component includes a power unit, a cam, a plug rod, a rotating rod, and a sliding column. The power unit is mounted on a support frame, and the cam is coaxially mounted on the output end of the power unit. The rotating rod is horizontally rotatably connected to the support frame, and guide grooves are provided at both ends of the rotating rod. A horizontally extending sliding groove is provided on the support frame. Half the length of the sliding groove is greater than the compression length of the elastic component. The length of the guide groove is greater than the maximum distance between the sliding column and the end of the sliding groove. The guide groove and the sliding groove intersect. The sliding column is fixedly connected to the outside of the plaster bucket and slides between the sliding groove and the guide groove. The inner end of the plug rod is fixedly connected to the middle of the rotating rod, and the outer end of the plug rod slides into the recess on the cam. The cam, plug rod, rotating rod, and sliding column are symmetrically arranged at both ends of the plaster bucket, and the input ends are all connected to the power unit by the plug rod.

[0011] Furthermore, the insertion rod is inclined, and the support frame is also provided with a return spring. The outer end of the return spring is connected to a return sleeve, and the return sleeve is hinged to the outer end of the insertion rod. The support frame is also provided with a positioning plate. When the return spring is in the normal state, the rotating rod is longitudinally arranged and the hinge point between the rotating rod and the slide groove is located at the center of the slide groove. When the return spring is in the compression limit position, one side of the rotating rod abuts against the side of the positioning plate.

[0012] Furthermore, the opening and closing component includes an opening and closing column, an opening and closing groove, an opening and closing sleeve, an upper guide seat, a pressing frame, a lower guide seat, a push table, a swing rod, a support rod, an extension rod, and an opening and closing spring. The opening and closing groove is formed on the end face of the plastering bucket, and the opening and closing groove is directly opposite the sliding cavity. The inner end of the opening and closing column is fixedly connected to the inner end of the plug. The outer end of the opening and closing column passes through the opening and closing groove and is coaxially fixedly connected to the opening and closing sleeve. The upper guide seat is located on the side of the plastering bucket, and one end of the pressing frame is horizontally inserted into the upper guide seat. The outer end of the pressing frame bends downward and faces the sliding column directly. The distance between the pressing frame and the sliding column is less than the compression distance of the elastic component. The lower guide seat is located on the side of the plastering bucket. One end of the push platform is horizontally slidably connected to the lower guide seat. The swing rod is rotatably connected to the side of the plastering bucket. One end of the pressing frame passes through the upper guide seat and is hinged to the top of the swing rod. The push platform is longitudinally slidably connected to the bottom end of the swing rod. The other end of the push platform has a contact portion extending outside the plastering bucket. The contact portion connects to... When the pressing frame touches the wall, it moves towards the wall, causing the top of the swing arm to move towards the wall, simultaneously driving the bottom of the swing arm to push the push platform. The distance of the contact part extending beyond the outer end of the plaster bucket is greater than half the length of the chute, and the distance between the sliding column and the front end of the pressing frame is less than half the length of the chute. When the contact part abuts against the wall, the plaster bucket continues to move in the same direction, causing the elastic component to compress and thus driving the pressing frame to move towards the wall. The support rod is rotatably connected to the side of the plaster bucket. The top of the swing arm is provided with an extension rod, which extends upwards towards the pressing frame. The two ends of the opening and closing spring are respectively connected to the top of the extension rod and the outer end of the support rod. When the sliding column squeezes the pressing frame, the swing arm rotates and simultaneously drives the push platform to push the opening and closing sleeve, causing the opening and closing sleeve to move away from the wall. The pushing force of the push platform on the opening and closing sleeve is greater than the elastic force of the elastic component on the plug. The push platform pushes the opening and closing sleeve to move away from the discharge port. When the opening and closing spring is in its normal state, one side of the opening and closing sleeve abuts against the push platform.

[0013] A building plastering method according to the present invention includes a plastering device and comprises the following steps:

[0014] S01. Installation: Install the longitudinal module and support frame, and fix the installation end of the longitudinal module to the bottom surface so that the distance between the plaster bucket and the wall is less than half the length of the chute, which satisfies the premise that the plaster bucket can contact the wall during the pushing process.

[0015] S02. The power unit drives the cam to rotate. Through the engagement between the insert rod and the recessed area on the cam, the outer end of the insert rod moves outward from the recess along the cam circumference. The insert rod swings, causing the rotating rod to rotate, thus compressing the return spring. The rotating rod separates from the positioning plate. The rotation of the rotating rod drives the sliding column to move along the slide groove towards the discharge port. The position of the sliding column is determined by the intersection of the slide groove and the guide groove, effectively ensuring the stable translation of the sliding column. The sliding column and the plaster bucket move synchronously, causing the plaster bucket to move towards the wall. Specifically, the power unit is a bidirectional motor with dual output shafts. When one plaster bucket moves towards the wall, it drives the other plaster bucket away from the wall, synchronously moving the plaster buckets. This satisfies the alternating reverse movement of the two plaster buckets, facilitating multiple alternating movements towards the wall within the unidirectional stroke of the longitudinal module, improving the efficiency of double-layer plastering and facilitating quick switching. The ash coating is provided. Furthermore, a positioning plate is also provided on the support frame via a reset spring and a positioning plate. When the reset spring is in its normal state, the rotating rod is longitudinally positioned and the hinge point between the rotating rod and the slide groove is located at the center of the slide groove, effectively determining the position of the rotating rod in the initial state, improving plastering accuracy, and preventing repeated adjustments to the plastering distance. When the reset spring is at its compression limit, one side of the rotating rod abuts against the side of the positioning plate, determining the limit position of the rotating rod driving the plaster bucket to move, facilitating the protection of the plaster bucket. Moreover, the cam has several evenly distributed recesses on its circumference. Each time the insert rod disengages from a recess, the rotating rod swings synchronously once, facilitating multiple swings of the rotating rod within one rotation of the cam. This allows for multiple translations of the plaster bucket within a very short cam rotation angle, quickly switching the position between two plaster buckets, easily meeting the plastering needs of multiple alternating plaster buckets.

[0016] S03. Specifically, in step S02, the feed pump is a bidirectional conveying pump. Before the plastering bucket contacts the wall, different plastering slurries are connected to the feed pipe. The corresponding feed pumps deliver the slurry into the plastering bucket. Through the set manifold, when the slurry is filled, it can accumulate in the plastering bucket by passing over the manifold, which makes it easy to ensure the amount of slurry at one time. Therefore, the side wall of the plastering bucket can be made of transparent material. When the amount of slurry accumulated inside the manifold reaches the predetermined amount, the slurry can be pumped back by the feed pump. The slurry blocked by the manifold will not be pumped away by the feed pump. Since the plug keeps blocking the outlet during this process, the amount of slurry delivered is effectively controlled.

[0017] S04. When plastering the wall from bottom to top, first fill the two plastering buckets with the corresponding first type of mortar and second type of mortar, respectively. The support frame is continuously moved upward by the longitudinal module. Specifically, the longitudinal module is an electric cylinder module, which facilitates precise control of the longitudinal movement of the plastering buckets and accurately positions the moving height of the plastering buckets. For simplicity, the plastering bucket located at the bottom is called the lower plastering bucket, and the plastering bucket located at the top is called the upper plastering bucket. When in the initial position, the rotating rod is set longitudinally. At this time, since the distance between the sliding column and the front end of the pressing frame is less than half the length of the sliding groove, it is convenient to effectively act on the pressing frame within the movement range of the sliding column, and can apply pressure to the pressing frame, which is convenient for the subsequent rotation of the swing rod. Since the distance of the contact part beyond the outer end of the upper plastering bucket is greater than half the length of the sliding groove, the pressing frame is already under pressure before the upper plastering bucket contacts the wall. Therefore, when the upper plastering bucket approaches the wall, the contact part contacts the wall first. The contact part is located outside the plastering area and does not affect the plastering operation. When the contact part abuts against the wall, the power unit drives the rotating rod to rotate, causing the sliding column to move at the intersection of the sliding groove and the guide groove. This intersection moves along the sliding groove towards the wall, causing the sliding column to move closer to the wall. The continued movement of the upper plaster bucket compresses the elastic component. Since half the length of the sliding groove is greater than the compression length of the elastic component, it is convenient to effectively compress or stretch the elastic component during the sliding of the sliding column. As the upper plaster bucket continues to move towards the wall through the contact part of the upper plaster bucket, the swing rod rotates when the sliding column presses against the pressing frame, simultaneously driving the pusher to push the opening and closing sleeve, causing the opening and closing sleeve to move away from the wall. Through the transmission relationship between the opening and closing components, the opening and closing sleeve moves away from the discharge port, simultaneously moving the corresponding plug in the upper plaster bucket away from the discharge port, thereby discharging the slurry and smoothly applying it to the wall. The wall is plastered using the first type of mortar in the upper plastering bucket. After plastering begins, the upper plastering bucket is moved upward by the longitudinal module, and the moving distance of the upper plastering bucket is determined to be 'a'. Then, the support frame is raised by the longitudinal module so that the outlet of the lower plastering bucket is aligned with the plastering position of the outlet of the upper plastering bucket. The outlet of the lower plastering bucket is aligned with the wall by the translation and opening / closing components. At the same time, the upper plastering bucket is moved back. When the upper plastering bucket is away from the wall, its outlet is sealed by the elastic component. After plastering is completed, the outlet can be quickly and automatically sealed to prevent mortar from leaking outside the outlet. The lower plastering bucket is filled with the second type of mortar. When the outlet of the lower plastering bucket is opened, the second type of mortar directly covers the first type of mortar, raising it to a height of 'a', thereby achieving double-layer plastering treatment of mortar at a height of 'a'.

[0018] S05. Since there is a certain distance between the outlets of the two plastering buckets, for example, during the plastering process from bottom to top, when the lower plastering bucket has finished plastering the area of ​​the upper plastering bucket, there is a gap between the outlet of the upper plastering bucket and the plastered area. In order to fill the plastering gap between the two outlets, after the lower plastering bucket has finished plastering, the longitudinal module needs to drive the support frame to move the distance between the two outlets downwards, effectively connecting the starting point of the upper plastering bucket's outlet with the ending point of the previous plastering, thus improving the integrity of the plastering.

[0019] The beneficial effects of this invention are:

[0020] After plastering is completed, the outlet can be quickly and automatically sealed to prevent slurry from leaking outside the outlet. It automatically achieves double-layer plastering treatment of slurry at a predetermined height, saving manpower, improving plastering efficiency, avoiding long-term slurry accumulation outside the outlet, reducing the formation of residual solid dirt, facilitating cleaning, and preventing the occupation of the effective plastering area of ​​slurry.

[0028] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0029] like Figure 1-5 As shown, a plastering device includes a longitudinal module 1. A support frame 2 is connected to the output end of the longitudinal module 1. Two plastering buckets 3 are horizontally slidably connected to the support frame 2. The support frame 2 is a gantry frame. The plastering buckets 3 are located inside the support frame 2. A discharge port 4 is opened at the front end of the plastering buckets 3. A translation component is provided on the support frame 2 to drive the two plastering buckets 3 to move synchronously in opposite directions. A plug 6 is provided inside the plastering bucket 3 to block the discharge port 4. An elastic component 7 is provided at the inner end of the plug 6. An opening and closing component is provided between the plug 6 and the plastering bucket 3. When the plastering bucket 3 moves to the discharge port 4 and abuts against the wall, the opening and closing component drives the plug 6 to separate from the discharge port 4.

[0030] like Figure 4 , 5 As shown, in this embodiment, the outer end of the plastering bucket 3 is connected to a feed pump 9, the feed pump 9 is provided with a feed pipe 10, the inner side of the plastering bucket 3 is provided with a protective cover 11, the protective cover 11 divides the plastering bucket 3 into two outer material areas 111 and an inner material area 112, the protective cover 11 is provided with a material hole 12, the inner end of the elastic component 7 is connected to the side of the protective cover 11 near the discharge port 4, the plug 6 is horizontally slidably connected to the protective cover 11, the inner side of the outer material area 111 is provided with a confluence plate 13, the top of the confluence plate 13 is inclined toward the protective cover 11, and the top of the confluence plate 13 is higher than the material hole 12.

[0031] After being pumped in by the feed pump 9, the slurry flows into the outer material zone 111. Through the accumulation of the slurry outside the manifold 13 or by adjusting the power of the feed pump 9, the slurry passes over the manifold 13 and accumulates in the inner material zone 112. The slurry flows through the material hole 12 and gathers between the inner side of the outlet 4 and the plug 6, effectively accumulating the slurry in advance. The accumulation of the slurry generates pressure on the slurry at the outlet 4, and the slurry can be discharged by utilizing the gravitational potential energy of the slurry when the plug 6 separates from the outlet 4, effectively saving energy in transportation.

[0032] In this embodiment, the protective cover 11 has a sliding cavity 14 on the side near the discharge port 4. A partition 15 is slidably fitted inside the sliding cavity 14. The inner side of the partition 15 is connected to the elastic component 7, and the inner end of the plug 6 is connected to the outer side of the partition 15. Through the partition 15, the column-blocking slurry extends into the elastic component 7, extending the service life of the elastic component 7.

[0033] like Figure 1 , 2As shown, in this embodiment, the translation component includes a power unit 51, a cam 52, a rod 53, a rotating rod 54, and a sliding column 55. The power unit 51 is mounted on the support frame 2. The cam 52 is coaxially mounted on the output end of the power unit 51. The rotating rod 54 is horizontally rotatably connected to the support frame 2. Guide grooves 541 are provided at both ends of the rotating rod 54. A horizontally extending sliding groove 201 is provided on the support frame 2. Half the length of the sliding groove 201 is greater than the compression length of the elastic component 7. The length of the guide groove 541 is greater than that of the sliding column 55. The maximum distance between the ends of the slide groove 201, the guide groove 541 intersects with the slide groove 201, the slide column 55 is fixedly connected to the outside of the plaster bucket 3, the slide column 55 slides through the slide groove 201 and the guide groove 541, the inner end of the insert rod 53 is fixedly connected to the middle part of the rotating rod 54, the outer end of the insert rod 53 slides in the recess 521 on the cam 52, the cam 52, the insert rod 53, the rotating rod 54 and the slide column 55 are symmetrically arranged at both ends of the plaster bucket 3 and the input ends are all connected to the power unit 51 by the insert rod 53.

[0034] like Figure 2 As shown, in this embodiment, the insertion rod 53 is inclined, and the support frame 2 is also provided with a return spring 16. The outer end of the return spring 16 is connected to a return sleeve 17, and the return sleeve 17 is hinged to the outer end of the insertion rod 53. The support frame 2 is also provided with a positioning plate 18. When the return spring 16 is in the normal state, the rotating rod 54 is arranged longitudinally and the hinge point between the rotating rod 54 and the slide groove 201 is located at the center of the slide groove 201. When the return spring 16 is in the compression limit position, one side of the rotating rod 54 abuts against the side of the positioning plate 18.

[0035] In this embodiment, the opening and closing components include an opening and closing column 81, an opening and closing groove 82, an opening and closing sleeve 83, an upper guide seat 84, a pressing frame 85, a lower guide seat 86, a push table 87, a swing rod 88, a support rod 89, an extension rod 881, and an opening and closing spring 891. The opening and closing groove 82 is formed on the end face of the plastering bucket 3 and is directly opposite the sliding cavity 14. The inner end of the opening and closing column 81 is fixedly connected to the inner end of the plug 6, and the outer end of the opening and closing column 81 passes through the opening and closing groove 82 and is coaxially fixedly connected to the opening and closing sleeve 83. The upper guide seat 84 is provided on the side of the plastering bucket 3, and one end of the pressing frame 85 is horizontally inserted into the upper guide seat 84. The outer end of the pressing frame 85... The pressure bracket 85 bends downward and faces the sliding column 55 directly. The distance between the pressure bracket 85 and the sliding column 55 is less than the compression distance of the elastic component 7. The lower guide seat 86 is located on the side of the plaster bucket 3. One end of the push platform 87 is horizontally slidably connected to the lower guide seat 86. The swing rod 88 is rotatably connected to the side of the plaster bucket 3. One end of the pressure bracket 85 passes through the upper guide seat 84 and is hinged to the top end of the swing rod 88. The push platform 87 is longitudinally slidably connected to the bottom end of the swing rod 88. The other end of the push platform 87 has a contact portion 871 extending outside the plaster bucket 3. When the contact portion 871 contacts the wall, the pressure bracket 85 moves toward the wall, causing the top end of the swing rod 88 to move toward the wall. The bottom end of the swing rod 88 is simultaneously driven to push the push platform 87; the distance of the contact part 871 beyond the outer end of the plaster bucket 3 is greater than half the length of the slide groove 201, and the distance between the sliding column 55 and the front end of the pressing frame 85 is less than half the length of the slide groove 201. When the contact part 871 abuts against the wall, the plaster bucket 3 continues to move in the same direction, causing the elastic component 7 to compress, thereby driving the pressing frame 85 to move towards the wall. The pushing force of the push platform 87 on the opening and closing sleeve 83 is greater than the elastic force of the elastic component 7 on the plug 6. The push platform 87 pushes the opening and closing sleeve 83 to move away from the discharge port 4. The support rod 89 is rotatably connected to the side of the plaster bucket 3. The top of 88 is provided with an extension rod 881, which extends upwards towards the pressing frame 85. The two ends of the opening and closing spring 891 are respectively connected to the top of the extension rod 881 and the outer end of the support rod 89. When the sliding column 55 presses the pressing frame 85, the swing rod rotates and simultaneously drives the push table 87 to push the opening and closing sleeve 83, causing the opening and closing sleeve 83 to move away from the wall. The pushing force of the push table 87 on the opening and closing sleeve 83 is greater than the elastic force of the elastic component 7 on the plug 6. The push table 87 pushes the opening and closing sleeve 83 to move away from the discharge port 4. When the opening and closing spring 891 is in the normal state, one side of the opening and closing sleeve 83 abuts against the push table 87.

[0036] like Figure 1-5 As shown, a building plastering method of the present invention includes a plastering device and includes the following steps:

[0037] S01. Installation: Install the longitudinal module 1 and the support frame 2, and fix the installation end of the longitudinal module 1 to the bottom surface so that the distance between the plaster bucket 3 and the wall is less than half the length of the chute 201, which satisfies the premise that the plaster bucket 3 can contact the wall during the pushing process.

[0038] S02. The power unit 51 drives the cam 52 to rotate. Through the cooperation between the insert rod 53 and the recess 521 on the cam 52, the outer end of the insert rod 53 moves out of the recess 521 along the circumference of the cam 52. The insert rod 53 swings, causing the rotating rod 54 to rotate, thereby compressing the return spring 16. The rotating rod 54 separates from the positioning plate 18. The rotation of the rotating rod 54 causes the sliding column 55 to move along the slide groove 201 towards the discharge port 4. The position of the sliding column 55 is determined by the intersection of the slide groove 201 and the guide groove 541, effectively ensuring the stability of the sliding column 55. The sliding column 55 moves synchronously with the plaster bucket 3, causing the plaster bucket 3 to move towards the wall. Specifically, the power unit 51 is a bidirectional motor with dual output shafts. Through symmetrically arranged translation and opening / closing components, it stably supports the plaster bucket 3 and effectively transmits torque and power, improving structural stability. When one plaster bucket 3 moves towards the wall, it drives the other plaster bucket 3 away from the wall, synchronously driving the plaster bucket 3 to move. This satisfies the alternating reverse movement of the two plaster buckets 3, facilitating multiple movements of the two plaster buckets 3 within the unidirectional stroke of the longitudinal module 1. The alternating movement of the rotating rod towards the wall improves the efficiency of double-layer plastering and facilitates quick switching of plaster coatings. Furthermore, through the provided return spring 16 and positioning plate 18, the support frame 2 also has a positioning plate 18. When the return spring 16 is in its normal state, the rotating rod 54 is longitudinally positioned and the hinge point between the rotating rod 54 and the slide groove 201 is located at the center of the slide groove 201, effectively determining the initial position of the rotating rod 54, improving plastering accuracy, and preventing repeated adjustments to the plastering distance. When the return spring 16 is at its compression limit position, one side of the rotating rod 54 abuts against the positioning plate. The side of the small plate 18 determines the extreme position of the movement of the plaster bucket 3 driven by the rotating rod 54, which is convenient for protecting the plaster bucket 3; moreover, the cam 52 has several recesses 521 evenly distributed in the circumferential direction. Every time the insert rod 53 disengages from the recess 521, the rotating rod 54 swings synchronously once, which makes it easy for the rotating rod 54 to swing multiple times within one rotation of the cam 52. This allows for multiple translations of the plaster bucket 3 within a very short rotation angle of the cam 52, quickly switching the position between two plaster buckets 3, which is convenient for meeting the plastering needs of multiple alternating plaster buckets 3.

[0039] S03. Specifically, in step S02, the feed pump 9 is a bidirectional conveying pump. Before the plastering bucket 3 contacts the wall, different plastering slurries are connected to the feed pipe 10. The corresponding feed pump 9 delivers the slurry into the plastering bucket 3. Through the set confluence plate, when the slurry is filled, it can accumulate in the plastering bucket 3 by passing over the confluence plate, which makes it easy to ensure the amount of slurry at one time. Therefore, the side wall of the plastering bucket 3 can be made of transparent material. When the amount of slurry accumulated inside the confluence plate reaches the predetermined amount, the slurry can be pumped back by the feed pump 9. The slurry separated by the confluence plate will not be pumped away by the feed pump 9. Since the plug 6 keeps blocking the outlet 4 during this process, the amount of slurry delivered is effectively controlled.

[0040] S04. When plastering the wall from bottom to top, first fill the two plastering buckets 3 with the corresponding first type of mortar and second type of mortar, respectively. The longitudinal module 1 drives the support frame 2 to move continuously upwards. Specifically, the longitudinal module 1 is an electric cylinder module, which facilitates precise control of the longitudinal movement of the plastering buckets 3 and accurately positions the moving height of the plastering buckets 3. For simplicity, the plastering bucket 3 located at the bottom is called the lower plastering bucket, and the plastering bucket 3 located at the top is called the upper plastering bucket. When in the initial position, the rotating rod 54 is set longitudinally. At this time, due to the sliding column 55 and the... The distance between the front ends of the pressure brackets 85 is less than half the length of the slide groove 201, which facilitates the effective action of the pressure brackets 85 within the movement range of the slide column 55, and can apply pressure to the pressure brackets 85, which facilitates the subsequent rotation of the swing rod 88. Since the distance of the contact part 871 beyond the outer end of the upper plaster bucket is greater than half the length of the slide groove 201, the pressure brackets 85 can be in a compressed state before the upper plaster bucket contacts the wall. Therefore, when the upper plaster bucket approaches the wall, the contact part 871 contacts the wall first. The contact part is located outside the plastering area and does not affect the plastering operation. When the contact part 871 abuts against the wall, the power unit 51 drives the rotating rod 54 to rotate, causing the sliding column 55 to move at the intersection of the sliding groove 201 and the guide groove 541. This intersection moves along the sliding groove 201 towards the wall, causing the sliding column 55 to move closer to the wall. The continued movement of the upper plaster bucket compresses the elastic component 7. Since half the length of the sliding groove 201 is greater than the compression length of the elastic component 7, it is convenient to effectively compress or stretch the elastic component 7 during the sliding process of the sliding column 55. As the upper plaster bucket continues to move towards the wall through the contact part 871, the upper plaster bucket presses against the pressing frame 85. When the sliding column 55 presses against the pressing frame 85, the swing rod 88 rotates and simultaneously drives the push table 87 to push the opening and closing sleeve 83, causing the opening and closing sleeve 83 to move away from the wall. Through the transmission relationship between the opening and closing components, the opening and closing sleeve 83 moves away from the discharge port 4, simultaneously causing the corresponding plug 6 in the upper plaster bucket to move away from the discharge port. 4. The slurry is discharged and smoothly applied to the wall. The wall is plastered using the first type of slurry in the upper plastering bucket. After the upper plastering bucket starts plastering, it is moved upward by the longitudinal module 1, and the moving distance of the upper plastering bucket is determined to be a. Then, the support frame 2 is raised by the longitudinal module 1 so that the outlet 4 of the lower plastering bucket is aligned with the plastering position of the outlet 4 of the upper plastering bucket. The outlet 4 of the lower plastering bucket is aligned with the wall by the translation component and the opening and closing component. At the same time, the upper plastering bucket is moved back. When the upper plastering bucket is away from the wall, its outlet 4 is sealed by the elastic component 7. After the plastering is completed, the outlet 4 can be quickly and automatically sealed to prevent the slurry from leaking outside the outlet 4. The lower plastering bucket is filled with the second type of slurry. When the outlet 4 of the lower plastering bucket is opened, the second type of slurry directly covers the first type of slurry, raising the height a, thereby realizing the double-layer plastering treatment of the slurry at the height a.

[0041] S05. Since there is a certain distance between the outlets 4 of the two plastering buckets 3, for example, during the plastering process from bottom to top, when the lower plastering bucket has finished plastering the area of ​​the upper plastering bucket, there is a gap between the outlet 4 of the upper plastering bucket and the plastered area. In order to fill the plastering gap between the two outlets 4, after the lower plastering bucket is finished, the longitudinal module 1 drives the support frame 2 to move the distance between the two outlets 4 downward as a whole, effectively connecting the starting point of the outlet 4 of the upper plastering bucket with the ending point of the previous plastering, thus improving the integrity of the plastering.

[0042] Therefore, the present invention can quickly and automatically seal the outlet 4 after plastering is completed, preventing the slurry from leaking outside the outlet 4, automatically achieving double-layer plastering treatment of slurry at a predetermined height, saving manpower, improving plastering efficiency, avoiding long-term accumulation of slurry outside the outlet 4, reducing the formation of residual solid dirt, facilitating cleaning, and preventing the occupation of the effective plastering area of ​​slurry.

4. A method for plastering a building, comprising the plastering device as described in claim 3, characterized in that, Includes the following steps: S01. Installation: Install the longitudinal module and support frame, and fix the installation end of the longitudinal module to the bottom surface so that the distance between the plaster bucket and the wall is less than half the length of the chute, which satisfies the premise that the plaster bucket can contact the wall during the pushing process. S02. The power unit drives the cam to rotate. Through the engagement between the insert rod and the recessed area on the cam, the outer end of the insert rod moves outward from the recess along the cam circumference. The insert rod swings, causing the rotating rod to rotate, thus compressing the return spring. The rotating rod separates from the positioning plate. The rotation of the rotating rod drives the sliding column to move along the slide groove towards the discharge port. The position of the sliding column is determined by the intersection of the slide groove and the guide groove, effectively ensuring the stable translation of the sliding column. The sliding column and the plaster bucket move synchronously, causing the plaster bucket to move towards the wall. The power unit is a bidirectional motor with dual output shafts. When one plaster bucket moves towards the wall, it drives the other plaster bucket away from the wall, synchronously moving the plaster buckets. This satisfies the alternating reverse movement of the two plaster buckets, facilitating multiple alternating movements towards the wall within the unidirectional stroke of the longitudinal module, improving the efficiency of double-layer plastering and facilitating quick switching of plaster coatings. The support frame is equipped with a positioning plate and a reset spring. When the reset spring is in its normal state, the rotating rod is longitudinally positioned and the hinge point between the rotating rod and the slide is located at the center of the slide, effectively determining the position of the rotating rod in the initial state, improving the accuracy of plastering and preventing repeated adjustments to the plastering distance. When the reset spring is at its compression limit, one side of the rotating rod abuts against the side of the positioning plate, determining the limit position of the rotating rod to move the plaster bucket, which is convenient for protecting the plaster bucket. Moreover, the cam has several recesses evenly distributed around its circumference. Each time the rod disengages from a recess, the rotating rod swings synchronously once, which allows the rotating rod to swing multiple times within one rotation of the cam. This enables multiple translations of the plaster bucket within a very short cam rotation angle, quickly switching the position between two plaster buckets, which is convenient for meeting the plastering needs of multiple alternating plaster buckets. S03. In step S02, the feed pump is a bidirectional conveying pump. Before the plastering bucket contacts the wall, different plastering slurries are connected to the feed pipe. The corresponding feed pumps deliver the slurry into the plastering bucket. Through the set manifold, when the slurry is filled, it can accumulate in the plastering bucket by passing over the manifold, which makes it easy to ensure the amount of slurry at one time. Therefore, the side wall of the plastering bucket is made of transparent material. When the amount of slurry accumulated inside the manifold reaches the predetermined amount, the feed pump draws back the slurry. The slurry blocked by the manifold will not be drawn away by the feed pump. Since the plug keeps blocking the outlet during this process, the amount of slurry delivered is effectively controlled. S04. When plastering the wall from bottom to top, first fill the two plastering buckets with the corresponding first type of mortar and second type of mortar, respectively. The longitudinal module, an electric cylinder module, drives the support frame to move continuously upwards, facilitating precise control of the plastering bucket's longitudinal movement and accurate positioning of its height. The lower plastering bucket is the lower plastering bucket, and the upper plastering bucket is the upper plastering bucket. In the initial position, the rotating rod is set longitudinally. At this time, because the distance between the sliding column and the front end of the pressing frame is less than half the length of the sliding groove, the pressing frame can effectively act within the sliding column's movement range, applying pressure to the pressing frame, facilitating subsequent... The continuous movement of the lever rotates the upper plastering bucket. Because the distance of the contact portion extending beyond the outer end of the upper plastering bucket is greater than half the length of the chute, the pressing frame is already under pressure before the upper plastering bucket contacts the wall. Therefore, when the upper plastering bucket approaches the wall, the contact portion contacts the wall first, and since the contact portion is outside the plastering area, it does not affect the plastering operation. After the contact portion abuts the wall, the power unit drives the rotating rod to rotate, causing the sliding column to move at the intersection of the chute and the guide groove. This intersection moves along the chute towards the wall, causing the sliding column to move closer to the wall. The continued movement of the upper plastering bucket compresses the elastic component. Since half the length of the chute is greater than the compression length of the elastic component... This design facilitates effective compression or stretching of the elastic components during the sliding process of the sliding column. The upper plaster bucket contacts the wall via its contact part, and as it continues to move towards the wall, the swing arm rotates when the sliding column presses against the pressing frame, simultaneously driving the pusher to push the opening and closing sleeve. This causes the opening and closing sleeve to move away from the wall, and through the transmission relationship between the opening and closing components, it moves the opening and closing sleeve away from the discharge port. Simultaneously, it moves the corresponding plug inside the upper plaster bucket away from the discharge port, thus discharging the slurry and smoothly applying it to the wall. The first type of slurry in the upper plaster bucket is used for plastering the wall. After the upper plaster bucket begins plastering, the longitudinal module moves it upwards to confirm the upper plastering process. The bucket moves a distance of 'a'. Then, the support frame is raised by the longitudinal module so that the outlet of the lower plastering bucket is aligned with the plastering position of the outlet of the upper plastering bucket. The outlet of the lower plastering bucket is aligned with the wall by the translation and opening / closing components. At the same time, the upper plastering bucket is moved back. When the upper plastering bucket is away from the wall, its outlet is sealed by the elastic component. After plastering is completed, the outlet can be quickly and automatically sealed to prevent the mortar from leaking outside the outlet. The lower plastering bucket is filled with the second type of mortar. When the outlet of the lower plastering bucket is opened, the second type of mortar directly covers the first type of mortar, raising the height by 'a', thereby achieving double-layer plastering treatment of the mortar at height 'a'. S05. Due to the distance between the outlets of the two plastering buckets, during the plastering process from bottom to top, when the lower plastering bucket has finished plastering the area of ​​the upper plastering bucket, there is a gap between the outlet of the upper plastering bucket and the plastered area. In order to fill the plastering gap between the two outlets, after the lower plastering bucket has finished plastering, the longitudinal module needs to drive the support frame to move the distance between the two outlets downwards, effectively connecting the starting point of the upper plastering bucket's outlet with the ending point of the previous plastering, thus improving the integrity of the plastering.
