Description

Technical Field

[0001] The invention relates to the technical field of building slurry, in particular to a slurry actuator and a slurry equipment. Background Art

[0002] At present, the slurry robot generally drives the actuator therein to perform slurry operation on the building wall in the way of smearing from top to bottom. The actuator rises from the bottom of the wall to the top of the wall while the scraper on the actuator smears upward at a certain angle. During the process of the actuator driving the scraper to smear upward, the feeding mechanism discharges the material into the hopper formed between the scraper and the wall, and then the lower edge of the scraper smears the slurry on the wall to achieve the smearing of the wall. Among them, the slurry robot detects the output of the slurry between the scraper and the wall through the slurry detection mechanism to control the pump to stop the discharge, but the slurry detection often cannot accurately control the slurry output, that is, the amount of slurry in the hopper is too much. When the scraper is scraped, the excessive slurry is easy to leak out of the hopper and fall to the ground. In the case of serious material drop, not only waste is caused, but also the slurry splashes everywhere after falling from the top of the wall to the ground, which also affects the personnel and working environment on site.

[0018] According to some embodiments of the present invention, the support frame includes a main frame at a rear position and side frames installed on the left and right sides of the main frame;

The two side frames are stopped at the left and right sides of the deformation part. When viewed along the left and right directions, the projection of the deformation part is located inside the side frames.

[0021] According to some embodiments of the present invention, the rear end of the rear plate body is fixedly mounted on the main frame, and the horizontal position of the front end of the rear plate body is lower than the horizontal position of the rear end of the rear plate body.

[0022] According to some embodiments of the present invention, the rear end of the rear plate is rotatably mounted on the main frame.

[0023] According to some embodiments of the present invention, the scraping portion has a scraping surface which is longitudinally arranged from left to right, the scraping surface faces the building surface and is configured as a plane which is inclined from back to front and downward, so that a scraping angle is formed between the scraping surface and the building surface;

[0024] The guide surface formed by the deformation portion in the second state is arranged to be inclined from the back to the front and downward, and the guide surface and the building surface form an angle space, and the angle space is located above the scraping angle;

[0025] When the deformation portion switches from the second state to the first state, the front end of the front plate body switches from a downwardly inclined setting from the back to the front to an upwardly inclined setting from the back to the front, and the scraping overflow from the scraping portion when it rises relative to the support frame flows from the scraping angle backwards into the material storage trough via the first end.

[0035] When the scraping part performs the upward scraping operation, the deformed part will gradually change from the second state to the first state, that is, the guide surface formed by the deformed part itself will gradually change to the storage tank for scooping materials, and excessive slurry will enter the storage tank from the hopper to prevent excessive slurry from overflowing the hopper and reducing the risk of material falling. Therefore, when the scraping part performs the upward scraping operation, it will carry out the slurry spreading operation while scooping materials, so that when the scraping part performs the upward scraping operation, the deformed part can form a storage tank for scooping materials, preventing excessive slurry from leaking out of the hopper and falling to the ground. In addition, the formed storage tank can store more slurry, and the storage capacity is increased, so the requirements for slurry detection accuracy do not need to be too high. Even if the slurry detection accuracy is low and the pump is not shut down in time, the excess slurry in the discharging mechanism can be stored in the storage tank.

[0036] In addition, the slurry stored in the storage tank can be further used for the next row of slurrying, thereby achieving slurry recycling and effectively saving the use of slurry resources.

[0037] More importantly, the slurry actuator can be used for slurry covering on the top of the wall. After the traditional actuator rises to the top of the wall, a scraper is used to flatten and squeeze the slurry onto the wall surface, i.e., the top is flattened to achieve slurry covering on the top of the wall. However, the slurry actuator in the embodiment of the present invention adopts a scraping part that can be raised and lowered and a deformation part that can switch between different states. Therefore, there is no need to adopt the top flattening method to achieve slurry covering on the top of the wall, and it can also effectively prevent serious problems of material falling.

[0038] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0049] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0050] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0052] Please refer to the following Figure 1-Figure 9 The slurry actuator and slurry device according to the embodiments of the present invention are described. Some implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0053] It should be noted that, in the present embodiment, the proximal end refers to the side of the object close to the building wall when the plastering operation is performed, the proximal direction refers to the direction vertically close to the building wall, the distal end refers to the side of the object away from the building wall when the plastering operation is performed, the distal direction refers to the direction vertically away from the building wall, and the left-right direction refers to the direction parallel to the building wall when the plastering operation is performed.

[0054] At present, the slurry robot generally drives the actuator therein to perform slurry operation on the building wall in the way of smearing from top to bottom. The actuator rises from the bottom of the wall to the top of the wall while the scraper on the actuator is smeared upward at a certain angle. During the process of the actuator driving the scraper to smear upward, the feeding mechanism discharges the material into the hopper formed between the scraper and the wall, and then the lower edge of the scraper smears the slurry 14 on the wall to achieve the smearing of the wall. Among them, the slurry robot detects the output of the slurry 14 between the scraper and the wall through the slurry 14 detection mechanism to control the pump to stop the discharge, but the slurry 14 detection often cannot accurately control the output of the slurry 14, that is, the amount of slurry 14 in the hopper is too much. When the scraper is scraped, the excessive slurry 14 is easy to leak out of the hopper and fall to the ground. In the case of serious material drop, not only waste is caused, but also the slurry 14 splashes everywhere after falling from the top of the wall to the ground, and also affects the personnel and working environment on site.

[0055] Furthermore, when the actuator rises to the top of the wall, the scraper will be used to flatten the wall surface and squeeze the slurry 14, that is, the top is flattened to achieve the slurry 14 covering the top of the wall. Since the slurry 14 detection often cannot accurately control the slurry 14 output, that is, the amount of slurry 14 in the hopper is too much, when the scraper performs the top flattening operation, the excessive slurry 14 is also easily squeezed out by the scraper and falls to the ground, which will also cause serious material drop.

[0056] In view of this, the slurry actuator in the embodiment of the present invention improves the relevant structure of the scraping part 2, and provides a deformation part 3 that can change its state between a first state and a second state to form a storage trough 4 or a guide surface, so that the deformation part 3 can form a storage trough 4 to scoop up the material when the scraping part 2 is scraping, thereby preventing excessive slurry 14 from leaking out of the hopper and falling to the ground.

[0057] For details, please refer to the attached Figure 1-Figure 9 The slurry actuator according to an embodiment of the present invention is used for slurrying on a building surface, and includes a support frame 1, a slurry scraping part 2 and a deformation part 3.

[0058] Among them, the scraping part 2 is installed on the support frame 1 and the scraping part 2 is configured to be able to make a lifting movement relative to the support frame 1, the deformation part 3 is connected between the support frame 1 and the scraping part 2, and the deformation part 3 is configured to be able to be linked to the lifting movement of the scraping part 2 and change the state between the first state and the second state; the deformation part 3 when changed to the first state can form a storage tank 4 for storing slurry 14 in the support frame 1, and the deformation part 3 when changed to the second state is configured to be able to form a guide surface in the support frame 1 to guide the slurry 14 to the scraping part 2.

[0059] In actual application, when the slurry actuator is slurrying the wall, the scraper part 2 will be initially at the bottom of the support frame 1. At this moment, the deformation part 3 will be changed to the second state to form a guide surface. The slurry 14 will be guided to the scraper part 2 through the guide surface, and then the scraper part 2 will move upward to slurry the wall.

[0060] When the scraping part 2 performs the upward scraping operation, the deformed part 3 will gradually change from the second state to the first state, that is, the guide surface formed by the deformed part 3 itself will gradually change to the storage tank 4 for scooping materials, and excessive slurry 14 will enter the storage tank 4 from the hopper to prevent excessive slurry 14 from overflowing the hopper and reducing the risk of material falling. Therefore, when the scraping part 2 performs the upward scraping operation, it will perform the slurry spreading operation while scooping materials, so that when the scraping part 2 performs the upward scraping operation, the deformed part 3 can form the storage tank 4 to scoop materials, preventing excessive slurry 14 from leaking out of the hopper and falling to the ground. In addition, the formed storage tank 4 can store more slurry 14, and the storage capacity is increased, and the requirements for the detection accuracy of the slurry 14 do not need to be too high. Even if the detection accuracy of the slurry 14 is low and the pump is not shut down in time, the excess slurry 14 in the discharging mechanism can be stored through the storage tank 4.

[0061] Furthermore, the slurry 14 stored in the storage tank 4 can be further used for the next row of slurrying, thereby achieving the recycling of the slurry 14 and effectively saving the use of slurry 14 resources.

[0062] More importantly, the slurry actuator can be used for covering the top of the wall with slurry 14. After the traditional actuator rises to the top of the wall, a scraper is used to flatten and squeeze the slurry 14 onto the wall surface, i.e., the top is flattened to achieve the slurry 14 coverage on the top of the wall. However, the slurry actuator in the embodiment of the present invention adopts a scraper part 2 that can be raised and lowered and a deformation part 3 that can switch between different states. Therefore, there is no need to adopt the top flattening method to achieve the slurry 14 coverage on the top of the wall, and it can also effectively prevent the serious problem of material falling.

[0063] Further, the specific structure of the deformation part 3 can be referred to in the attached Figure 1-Figure 6 According to the slurry actuator in an embodiment of the present invention, the deformation portion 3 extends between the first end and the second end, the first end is connected to the scraping portion 2, and the second end is connected to the support frame 1; when the deformation portion 3 is in the first state, the deformation portion 3 is concave to form a material storage trough 4, and the horizontal position of the first end and the horizontal position of the second end are both higher than the bottom of the material storage trough 4; when the deformation portion 3 is in the second state, the horizontal position of the first end is lower than the second end, and the first end is at the bottom position of the deformation portion 3.

[0064] In practical applications, the deformation portion 3 can be switched between a first state and a second state, wherein the deformation portion 3 in the first state can form a storage tank 4, Figure 8 The specific shape is concave, and both ends of the storage tank 4 are higher than the bottom of the storage tank 4, which can effectively store the slurry 14. The deformation portion 3 in the second state can form a downwardly inclined guide surface, referring to Figure 7 The slurry 14 is guided to the scraping part 2 through the guide surface by its own weight and fluidity to carry out slurry application on the wall.

[0065] Further, the specific structure of the deformation part 3 can also refer to the attached Figure 1-Figure 6 According to the slurry actuator in an embodiment of the present invention, the deformation part 3 includes a front plate body 301 and a rear plate body 302, the front end of the front plate body 301 is rotatably connected to the scraping part 2 and is linked to the lifting movement of the scraping part 2, the rear end of the front plate body 301 is rotatably connected to the front end of the rear plate body 302, the rear end of the rear plate body 302 is connected to the support frame 1, the front end of the front plate body 301 constitutes the first end, and the rear end of the rear plate body 302 constitutes the second end.

[0066] In actual application, the deformation part 3 specifically includes a front plate body 301 and a rear plate body 302, and the scraper part 2, the front plate body 301 and the rear plate body 302 are rotatably connected in pairs in sequence. Therefore, when the scraper part 2 is driven to make a lifting movement relative to the support frame 1, the scraper part 2 will drive the front plate body 301 to lift and lower, and then a material storage trough 4 or a guide surface can be formed between the front plate body 301 and the rear plate body 302 to realize switching between the first state and the second state.

[0067] Further, the specific structure of the deformation part 3 can also refer to the attached Figure 1-Figure 6 According to the slurry actuator in an embodiment of the present invention, when the deformation portion 3 is in a first state, the horizontal position of the front end of the front plate body 301 is higher than the horizontal position of the rear end of the front plate body 301, the plate surface of the front plate body 301 in contact with the slurry 14 forms the front wall of the storage tank 4, and the plate surface of the rear plate body 302 in contact with the slurry 14 forms the rear wall of the storage tank 4; when the deformation portion 3 is in a second state, the horizontal position of the front end of the front plate body 301 is lower than or flush with the horizontal position of the rear end of the front plate body 301, the horizontal position of the front end of the rear plate body 302 is lower than the horizontal position of the rear end of the rear plate body 302, the plate surface of the rear plate body 302 is connected to the plate surface of the front plate body 301 and both are inclined downward from the back to the front to form a guide surface for guiding the slurry 14 to the scraping portion 2.

[0068] In actual application, when the deformation part 3 is in the first state, the plate surfaces of the front plate 301 and the rear plate 302 are connected to form a concave state, so that the space between the two forms a storage tank 4, and because the horizontal position of the front end of the front plate 301 is higher than the horizontal position of the rear end, the front plate 301 is inclined from back to front and upward, and the scraping part 2 is arranged at the front end of the front plate 301. Therefore, the slurry 14 flowing from the rear plate 302 from back to front and downward will flow into the groove cavity of the storage tank 4 to achieve the purpose of storing the slurry 14. When the deformation portion 3 is in the second state, the horizontal position of the scraping portion 2 is at the lowest horizontal position of the guide surface. In this case, the slurry 14 on the guide surface will automatically flow to the scraping portion 2 under the action of its own gravity. There is no need to provide a corresponding power pushing device. The guide surface can achieve the purpose of guiding the slurry 14 to automatically flow to the scraping portion 2, and the characteristic of flowing to a lower place under the action of gravity can be used to guide the slurry 14 to flow.

[0069] More importantly, the volume of the formed storage tank 4 can be enlarged with the upward movement of the scraping part 2, and can store more slurry 14, further increase the amount of material in the storage tank 4, and prevent excessive slurry 14 from leaking out of the hopper and falling to the ground. In addition, the volume of the storage tank 4 can also be reduced relative to the downward movement of the support frame 1, so as to achieve the purpose of recycling the slurry 14 retained by the previous row of slurry operation, recycling the excess slurry 14, avoiding waste, and quickly achieving the purpose of recycling the slurry 14 without the need for re-pumping and spraying operations of the recovery barrel and the discharge head 9, thereby reducing the production cost.

[0070] Further, the specific structure of the deformation part 3 can also refer to the attached Figure 1-Figure 6 According to the slurry actuator in the embodiment of the present invention, the deformation portion 3 also includes an intermediate plate body 303 extending transitionally between the front plate body 301 and the rear plate body 302, the front end of the intermediate plate body 303 is rotatably connected to the rear end of the front plate body 301, and the rear end of the intermediate plate body 303 is rotatably connected to the front end of the rear plate body 302.

[0071] In actual applications, the deformation part 3 specifically includes a front plate body 301, an intermediate plate body 303 and a rear plate body 302, and is specifically composed of three plates. The intermediate plate body 303 is correspondingly designed between the front plate body 301 and the rear plate body 302, so that the front plate body 301, the intermediate plate body 303 and the rear plate body 302 can form a movable chain plate structure that is rotated in series in sequence, thereby achieving the effect of improving the freedom of movement, and further improving the flexibility of the overall bending deformation of the guide surface formed by the front plate body 301, the intermediate plate body 303 and the rear plate body 302. At the same time, it also plays a role in satisfying the structural connection requirements that the front plate body 301 can perform linear lifting and lowering movements in the vertical direction, so as to achieve the purpose of ensuring the stability of the structural operation.

[0072] Among them, in the rotating connection structure, it is preferred to adopt a hinge 5 connection structure, that is, the front plate 301 and the scraping part 2, the front plate 301 and the middle plate 303, and the middle plate 303 and the rear plate 302 are all rotatably connected through the hinge 5.

[0073] Further, the specific structure of the deformation part 3 can also refer to the attached Figure 1-Figure 6 According to the slurry actuator in the embodiment of the present invention, the number of the intermediate plates 303 is set to be multiple, and any two adjacent intermediate plates 303 are configured to be rotatably connected. The intermediate plate 303 in the front position is rotatably connected to the front plate 301, and the intermediate plate 303 in the rear position is rotatably connected to the rear plate 302, which can further improve the flexibility of the bending deformation of the guide surface.

[0074] Further, the specific structure of the support frame 1 can be referred to in the attached Figure 1-Figure 6 According to the slurry actuator in the embodiment of the present invention, the support frame 1 includes a main frame 101 at the rear position and side frames 102 installed on the left and right sides of the main frame 101; the front ends of the two side frames 102 are installed with slide rails 602, and the left and right sides of the scraping part 2 are respectively slidably connected to the slide rails 602 to guide the scraping part 2 to rise and fall; the front end of the deformation part 3 is rotatably connected to the scraping part 2, the deformation part 3 is arranged between the two side frames 102, and the two side frames 102 are stopped on the left and right sides of the deformation part 3. When viewed along the left and right directions, the projection of the deformation part 3 is located inside the side frames 102.

[0075] In practical applications, the slurry-spreading actuator can be provided with side frames 102 on both sides of the deformation part 3, so that the side frames 102 can prevent the slurry 14 from flowing out of the deformation part 3 from the left and right sides of the deformation part 3, so as to avoid the waste of the slurry 14. In addition, the slide rail 602 is provided in a vertical direction to meet the structural requirement that the slurry-scraping part 2 can move up and down relative to the support frame 1.

[0076] Further, the specific structure of the support frame 1 can be referred to in the attached Figure 1-Figure 6 According to the slurry smearing actuator in the embodiment of the present invention, the rear end of the rear plate 302 is fixedly mounted on the main frame 101, and the horizontal position of the front end of the rear plate 302 is lower than the horizontal position of the rear end of the rear plate 302. In this way, the rear plate 302 can automatically guide the slurry 14 to flow in the direction close to the slurry scraping part 2.

[0077] In some other embodiments, the rear end of the rear plate 302 is rotatably mounted on the main frame 101, which is more conducive to improving the overall adaptability of the support frame 1 when the guide surface undergoes bending changes.

[0078] Further, the specific structure of the scraping part 2 can be referred to in the attached Figure 1-Figure 6According to the slurry actuator in the embodiment of the present invention, the scraping part 2 has a scraping surface arranged in the left-right longitudinal direction, the scraping surface faces the building surface and is configured as a plane inclined from back to front and downward, so that a scraping angle 7 is formed between the scraping surface and the building surface; the guide surface formed by the deformation part 3 in the second state is inclined from back to front and downward, and the guide surface and the building surface form an angle space 8, and the angle space 8 is located above the scraping angle 7; when the deformation part 3 switches from the second state to the first state, the front end of the front plate body 301 switches from the downward inclined setting from back to front to the upward inclined setting from back to front, and the scraping overflow of the scraping part 2 when it rises relative to the support frame 1 enters the storage tank 4 from the scraping angle 7 through the first end backwards.

[0079] In practical applications, by providing a planar scraping portion 2, the edge of the scraping portion 2 is a straight line, so when the edge of the scraping portion 2 is used to scrape the slurry 14 on the wall, it is easy to form a plane, which plays a role in ensuring the flatness of the slurry 14 layer. In addition, the angle space 8 is located above the scraping angle 7, so that the slurry 14 on the guide surface can flow into the scraping portion 2.

[0080] Among them, the scraping part 2 can be specifically constructed into a roller shape or a plate shape. By setting up the roller-shaped or plate-shaped scraping part 2, the edges that contact the slurry 14 in the wall surface to form a slurry layer are all straight lines. Therefore, when using its edges to scrape the slurry 14 on the wall surface, it is easy to form a plane. Therefore, the scraping part 2 with a roller-shaped or plate-shaped structure can ensure the flatness of the slurry 14 layer.

[0081] Further, the driving structure for providing power for the lifting movement of the scraping part 2 can be specifically referred to in the attached Figure 1-Figure 6 According to the slurry-spreading actuator in the embodiment of the present invention, it also includes a driving mechanism 6 for driving the scraping part 2 to perform lifting movement relative to the support frame 1. The driving mechanism 6 is installed on the support frame 1 and connected to the scraping part 2; the driving mechanism 6 drives the scraping part 2 to perform lifting movement. The range of motion of the driving mechanism 6 is configured to be able to penetrate the horizontal position of the first end of the deformation part 3.

[0082] In actual application, the purpose of driving the scraper 2 to move up and down can be achieved by driving the scraper 2 to move back and forth along the slide rail 602 relative to the support frame 1 through the driving mechanism 6. In addition, since the scraper 2 is rotatably connected to the front end of the front plate 301, when the scraper 2 moves to a horizontal position higher than the horizontal position of the rear plate 302 under the drive of the driving mechanism 6, the front end of the front plate 301 will naturally be higher than the horizontal position of the rear plate 302. In this case, the front plate 301 can completely block the slurry 14 in the guide storage tank 4 from flowing to the scraper 2, thereby achieving the purpose of completely temporarily storing the slurry 14 flowing on the guide surface, that is, achieving the purpose of completely blocking the slurry 14 from being guided to the scraper 2 at the top position of the support frame 1.

[0083] For details, the specific structure of the driving mechanism 6 can also be found in the attached Figure 1-Figure 6 According to the slurry smearing actuator in the embodiment of the present invention, the driving mechanism 6 includes a screw motor 601, the screw of the screw motor 601 is vertically arranged on the side of the side frame 102 to form a slide rail 602, and the motor head of the screw motor 601 is connected to the slurry scraping part 2. The structure of the commercially available screw motor 601 is directly adopted, which is convenient to obtain materials, has good structural integrity, and is easy and quick to install.

[0084] Of course, in other embodiments, the driving mechanism 6 can also be a screw-nut transmission mechanism commonly used in the prior art, or a linear cylinder, or a structure that can drive the scraper part 2 to perform linear reciprocating motion in the vertical direction, as long as it can drive the scraper part 22 to perform lifting motion relative to the support frame 11. The pivotal connection between the front plate 301 and the rear plate 302 and the mutual rotational relationship between the two ends of the intermediate plate 303 increase the bending freedom of the guide surface formed by the combination of the three, so that the front end of the front plate 301 can realize the purpose of linear motion in the vertical direction in conjunction with the scraper part 2. That is, the intermediate plate 303 is added between the front plate 301 and the rear plate 302, which not only increases the bending freedom of the guide surface as a whole, but also meets the structural requirements of the combination of the front plate 301 and the scraper part 2 that can perform lifting motion in the vertical direction, so that the guide surface can realize the purpose of bending change in conjunction with the lifting motion of the scraper part 2. Moreover, the front end of the front plate 301 is directly rotatably connected to the scraper part 2, and the purpose of adaptive change can be achieved without the need for an additional power structure that drives the deformation part 3 to perform bending deformation. This is obviously beneficial to reducing the cost of structural design.

[0085] Further, the discharging structure can be specifically referred to in the attached Figure 1-Figure 6 According to the slurry actuator in the embodiment of the present invention, it also includes a discharge head 9 for conveying slurry 14. The discharge head 9 is arranged on the main frame 101, and the discharge head 9 is located above the second end of the deformation portion 3.

[0086] In actual application, the discharge head 9 discharges the slurry 14, and the slurry 14 will fall onto the rear plate 302 at the bottom of the discharge head 9. Since the rear plate 302 is arranged to be inclined downward from the back to the front, the slurry 14 can flow toward the scraping part 2 in the front position under the action of its own gravity, thereby achieving the purpose of guiding the slurry 14 to the scraping part 2.

[0087] The embodiment of the present invention not only proposes a slurry actuator, but also proposes a slurry device including the slurry actuator.

[0088] For details, please refer to the attached Fig. 9 According to the slurry spreading equipment in the embodiment of the present invention, it includes a movable base 10, a lifting mechanism 11, a lifting seat 12 and the above-mentioned slurry spreading actuator; the lifting mechanism 11 is installed on the movable base 10, and the movable base 10 carries the slurry spreading actuator to move to the working site to perform multi-row slurry spreading operations. The lifting mechanism 11 drives the slurry spreading actuator to scrape the slurry from bottom to top in each row of slurry spreading operations to achieve the purpose of multi-row reciprocating slurry spreading.

[0089] For further information, see Attachment Fig. 9 According to the slurrying equipment in the embodiment of the present invention, it also includes a top support mechanism 13 that can abut against the building ceiling surface, and the top support mechanism 13 is installed on the top of the lifting seat 12.

[0090] In actual application, when performing the slurry operation from bottom to top, the top support mechanism 13 is driven to rise to the building ceiling and abut against the ceiling, so that the entire slurry equipment can provide sufficient support force for the slurry operation of the scraper part 2.

[0091] Therefore, the slurry actuator can be used alone to carry out slurrying on the wall surface of the wall, or can be combined with the movable base 10, the lifting mechanism 11, the lifting seat 12 and the supporting mechanism 13. The lifting mechanism 11 can be used to lift the slurry actuator to carry out slurrying on the wall surface other than the top of the wall, and the slurry actuator itself can also be lifted to carry out slurrying on the wall surface at the top of the wall. The latter is the most important application scope, as follows:

[0092] In the specific slurry operation, refer to Figure 7 , Figure 8 and Fig. 9 When the scraper part 2 is located at the bottom of the support frame 1, the guide surface formed by the front plate 301, the middle plate 303 and the rear plate 302 is a slope structure inclined downward from the back to the front. At this moment, it is the second state of the deformation part 3. The slurry 14 flows out from the discharge head 9 and falls on the guide surface. It is squeezed into the space between the scraper part 2 and the wall by the weight of the slurry 14 and the fluidity of the slurry 14.

[0093] When it is necessary to perform a plastering operation on the wall from bottom to top, the slurry actuator keeps the scraper part 2 in the relative position at the bottom of the support frame 1 unchanged during the process of rising from the bottom of the wall to the top of the wall, and the scraper part 2 smoothes the slurry 14 on the wall to form a mortar layer 15 as the slurry actuator rises, that is, the slurry operation; when the slurry actuator rises to the top of the wall under the drive of the lifting mechanism 11, the slurry actuator is kept against the ceiling and then the scraper part 2 at the bottom of the slurry actuator is driven to start moving upward along the support frame 1, so as to drive the scraper part 2 to perform the slurrying operation on the wall within the height range of the support frame 1. At the same time, during this slurrying operation, the guide plate will link the scraper part 2 with the upward movement relative to the support frame 1 and present a concave state to form a material storage trough 4, and the deformation part 3 gradually switches from the second state to the first state, so as to achieve the purpose of the scraper part 2 driving the deformation part 3 to form a material storage trough 4 to temporarily store excess slurry 14.

[0094] When one row of plastering operations is completed and the next row of plastering operations is started at the bottom, the support frame 1 of the plastering actuator is driven by the lifting mechanism 11 to move downward back to the bottom of the plastering equipment, and then the scraper part 2 is driven to move downward relative to the support frame 1 to move to the bottom of the support frame 1. At this moment, the deformation part 3 is switched to the second state to form a slope state from back to front and inclined downward to release the slurry 14 temporarily stored in the previous row of plastering operations. At the same time, the discharging head 9 starts to discharge material, and the plastering actuator starts to plaster from the bottom of the wall to the top, and the above operations are repeated to complete the plastering operation of the entire wall, thereby achieving the purpose of recycling and reusing the slurry 14 and reducing the impact of material falling from the top on the working environment.

[0095] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
