Description

Technical Field

[0001] This utility model relates to the field of wall plastering technology, and in particular to a plastering tool for wall plastering. Background Technology

[0002] In plastering projects for building construction, wall grouting is a crucial preliminary step that plays an irreplaceable role in improving the adhesion between the grout and the wall and effectively preventing hollow spots. The grouting process aims to evenly apply grout to the wall surface using a specific method, forming a dense network of grout dots, which in turn creates a friction surface conducive to the firm adhesion of subsequent plaster layers.

[0003] Traditionally, this process relied primarily on manually operated slurry-applying equipment. This equipment was relatively simple in construction, consisting mainly of a slurry-applying board and a plastic tube. During operation, the worker held the plastic tube and repeatedly swung it back and forth, applying the slurry-soaked board to the wall surface. This process required a certain level of physical strength and endurance, as effective slurry application depended not only on appropriate force but also on ensuring the frequency and uniformity of the application to achieve the desired wall coverage.

[0004] However, this traditional manual plastering method has many shortcomings. First, because it requires prolonged and intensive swinging of the plastering board, workers' arms are highly susceptible to injury, significantly increasing the risk of occupational diseases such as muscle strain and joint pain. Second, manual plastering is inefficient, consuming a large amount of labor resources and limiting project progress. This limitation is particularly pronounced when constructing large-area walls. Utility Model Content

[0005] The purpose of this invention is to provide a paddle for applying plaster to walls, so as to solve the problem that the traditional wall plastering process requires manual repeated back-and-forth swinging of the equipment, which is labor-intensive and inefficient.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A trowel for applying plaster to walls includes: a trowel assembly, a trowel arm assembly, and a trowel support assembly. The trowel arm assembly is connected to the trowel assembly via the trowel support assembly. The trowel arm assembly is handheld to move the trowel assembly. A plaster driving assembly includes an elastic element and a traction element. The traction element is disposed on the trowel arm assembly, and one end of the traction element passes through the trowel support assembly and is connected to the trowel assembly. The trowel assembly can move closer to the trowel support assembly under the pulling action of the traction element. The elastic element is supported between the trowel assembly and the trowel support assembly. When the trowel assembly moves closer to the trowel support assembly, the elastic element has a rebound tendency, so that when the pulling action disappears, the trowel assembly can repeatedly move away from and closer to the trowel support assembly.

[0008] Based on the aforementioned technical means, the slurry-patting paddle of this invention achieves automatic reciprocating motion of the patting surface assembly through the coordinated action of the elastic and traction components of the slurry-patting drive component. Operators only need to hold the paddle arm assembly and pull or release the traction component as needed to control the patting surface assembly to move closer to or further away from the wall for slurry-patting operations. This fundamentally solves the problem of traditional slurry-patting paddles requiring repeated manual swinging, significantly improving the automation level of slurry-patting operations.

[0009] Meanwhile, the introduction of the slurry-driving component eliminates the need for operators to repeatedly swing the slurry-driving board using their arm strength, significantly reducing physical exertion and the risk of arm injury. The elastic rebound characteristic of the slurry-driving component allows the slurry-driving assembly to automatically move back and forth towards the slurry-driving support component after the pulling action disappears, thus achieving continuous and uniform slurry-driving action. This automated slurry-driving method not only improves work efficiency but also ensures the uniformity and consistency of the wall slurry coverage, enhancing the quality of the plastering project.

[0010] Furthermore, the paddle driving assembly also includes a guide assembly, the traction member is connected to the guide assembly, and the guide assembly is used to limit the distribution of the traction member along the length direction of the paddle assembly.

[0011] Based on the above technical means, the guide component provides a stable motion path for the traction component, ensuring the smoothness and accuracy of the traction component during the pulling and releasing process. This helps to reduce uneven slurrying caused by swaying or deviation of the traction component, and improves the quality of slurrying operations.

[0012] Furthermore, the guide assembly includes a guide shaft and a lifting ring. The guide shaft is mounted on the racket face support assembly, and the lifting ring is mounted on the racket shaft assembly at the end away from the racket face support assembly. The traction member is respectively disposed on the racket shaft assembly through the guide shaft and the lifting ring, and one end of the traction member bypasses the guide shaft and is connected to the racket face assembly.

[0013] According to the aforementioned technical means, the guide shaft is mounted on the paddle support assembly, providing a clear movement path for the traction component. When the traction component is pulled or released, it moves smoothly along the guide shaft, ensuring that the paddle assembly can perform the paddle action according to the predetermined trajectory. This design reduces the swaying and offset of the traction component, improving the accuracy and uniformity of the paddle action.

[0014] The lifting ring is installed at the end of the paddle assembly furthest from the paddle face support assembly, providing a stable support point for the other end of the traction component. This helps balance the tension of the traction component and prevents the paddle face assembly from swaying or deviating from the target position due to uneven tension. Therefore, the paddle operation is more stable and reliable.

[0015] This invention, through the cooperation of the guide shaft and the lifting ring, allows the traction component to be easily installed and removed from the racket arm assembly, simplifying the operation process for workers and reducing installation and debugging time.

[0016] Furthermore, the paddle driving assembly also includes a switch, which is mounted on the paddle assembly and located between the guide shaft and the lifting ring; the other end of the traction member passes around the lifting ring and folds back to connect with the switch, and the switch is used to pull the traction member.

[0017] Based on the aforementioned technical means, the addition of a switch allows operators to more conveniently control the pulling and releasing of the traction component. By simply operating the switch, rapid tamping of the tamping assembly can be achieved without manually pulling or releasing the traction component, greatly improving operational convenience. Simultaneously, the switch enables more precise control of the traction component's tamping rhythm and intensity. Operators can adjust the tamping frequency and intensity by operating the switch quickly or slowly as needed, thereby achieving more efficient tamping operations.

[0018] Furthermore, the traction component includes a first traction rope and a second traction rope, the first traction rope being connected to the second traction rope, one end of the second traction rope passing around the hanging ring and folding back to connect to the switch; one end of the first traction rope passing around the guide shaft and connecting to the beater assembly.

[0019] Based on the aforementioned technical means, this utility model, by dividing the traction component into two parts, allows for more precise control of the distribution of traction force. The first traction rope is responsible for pulling the paving assembly toward or away from the wall, while the second traction rope controls the start and stop of the entire traction action via a switch, enabling the operator to more accurately control the force and rhythm of paving.

[0020] Furthermore, the switch includes a button and a hook. The hook is rotatably mounted on the racket arm assembly. The button abuts against one end of the hook and is used to push the other end of the hook to rotate in a direction away from the hanging ring. The other end of the hook is connected to one end of the second pull rope. When the hook rotates in a direction away from the hanging ring, the hook can pull the second pull rope to move, thereby driving the first pull rope, so that the racket face assembly can move closer to the racket face support assembly under the pulling action of the first pull rope.

[0021] Based on the aforementioned technical means, the combination of buttons and hooks makes operation simpler and more intuitive. Operators only need to press the button to rotate the hook and move the traction component, thereby reducing the difficulty of operation and improving work efficiency.

[0022] Furthermore, the paddle assembly includes a paddle plate and an outer frame, the outer frame being fixed around the paddle plate; the paddle support assembly is mounted on the outer frame, such that the paddle rod assembly is connected to the paddle assembly via the paddle support assembly; one end of the traction member passes through the paddle support assembly and is connected to the paddle plate, allowing the paddle plate to move closer to the paddle support assembly under the traction of the traction member; the elastic member is supported between the paddle plate and the paddle support assembly.

[0023] Based on the aforementioned technical means, the outer frame is fixed around the slurry-beating plate, enhancing the overall structural stability of the slurry-beating assembly. This allows the slurry-beating plate to withstand greater impact forces during the slurry-beating process without easily deforming or being damaged. The slurry-beating support assembly is mounted on the outer frame, providing a stable support point for the connection between the slurry-beating arm assembly and the slurry-beating assembly. This ensures that the traction force can be transmitted evenly and stably to the slurry-beating plate, improving the accuracy and stability of the slurry-beating operation.

[0024] Furthermore, it also includes a movable component, which is installed on the side of the outer frame away from the racket face support component. The movable component is used to abut against the wall and drive the racket face component to move.

[0025] Using the aforementioned technology, the movable component can be directly attached to the wall surface. By pushing or pulling it, the entire mortar assembly can be easily moved across the wall. This greatly simplifies the construction process, reduces the time and physical exertion of manually moving the mortar applicator, and thus improves construction efficiency.

[0026] Furthermore, the moving component includes at least four balls, each ball being rotatably mounted on the outer frame, and the balls being evenly distributed.

[0027] Based on the aforementioned technical means, the ball bearings installed on the outer frame enable the patting assembly to move closely and smoothly against the wall surface, which not only reduces bumps and pauses during movement, but also ensures the continuity and smoothness of the patting operation, thereby improving the overall construction efficiency.

[0028] At the same time, the ball bearings can significantly reduce the movement resistance of the cladding assembly on the wall, making it easier for operators to push or pull the cladding assembly to perform operations, reducing physical exertion and time waste, and further improving construction efficiency.

[0029] Furthermore, it also includes a rotating component, wherein the racket face support component is rotatably connected to the racket shaft component via the rotating component.

[0030] Based on the aforementioned technical features, the rotating assembly allows the trowel support assembly to rotate relative to the trowel assembly, enabling operators to adjust the angle and position of the trowel assembly as needed. This flexibility not only improves construction efficiency but also allows for more precise coverage of all corners and hard-to-reach areas of the wall during the troweling process.

[0031] The beneficial effects achieved by this utility model are:

[0032] This invention's slurry-patting paddle achieves automatic reciprocating motion of the slurry-patting assembly through the coordinated action of the elastic and traction components of the slurry-patting drive component. Operators only need to hold the paddle arm assembly and pull or release the traction component as needed to control the slurry-patting assembly to move closer to or further away from the wall for slurry-patting operations. This fundamentally solves the problem of traditional slurry-patting paddles requiring repeated manual swinging, significantly improving the automation level of slurry-patting operations.

[0033] Meanwhile, the introduction of the slurry-driving component eliminates the need for operators to repeatedly swing the slurry-driving board using their arm strength, significantly reducing physical exertion and the risk of arm injury. The elastic rebound characteristic of the slurry-driving component allows the slurry-driving assembly to automatically move back and forth towards the slurry-driving support component after the pulling action disappears, thus achieving continuous and uniform slurry-driving action. This automated slurry-driving method not only improves work efficiency but also ensures the uniformity and consistency of the wall slurry coverage, enhancing the quality of the plastering project.

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0048] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

[0049] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0050] The technical solution of this embodiment will be described in detail below with reference to the accompanying drawings.

[0051] like Figure 1 As shown, this embodiment proposes a slapping tool for wall slurry application, comprising: a slapping surface assembly 1, a slapping rod assembly 2, and a slapping surface support assembly 3. The slapping rod assembly 2 is connected to the slapping surface assembly 1 via the slapping surface support assembly 3. The slapping rod assembly 2 can be held by hand to move the slapping surface assembly 1. A slapping driving assembly includes an elastic element 41 and a traction element 42. The traction element 42 is disposed on the slapping rod assembly 2, and one end of the traction element 42 passes through the slapping surface support assembly 3 and is connected to the slapping surface assembly 1. The slapping surface assembly 1 can move closer to the slapping surface support assembly 3 under the pulling action of the traction element 42. The elastic element 41 is supported between the slapping surface assembly 1 and the slapping surface support assembly 3. When the slapping surface assembly 1 moves closer to the slapping surface support assembly 3, the elastic element 41 has a rebound tendency, so that when the pulling action disappears, the slapping surface assembly 1 can repeatedly move away from and closer to the slapping surface support assembly 3.

[0052] The specific steps for applying plaster to the wall surface using the plastering applicator designed above are as follows:

[0053] 1. Preparation stage: Prepare an appropriate amount of slurry material and ensure that the slurry is stirred evenly and has a suitable viscosity.

[0054] 2. Applying the grout: Immerse the grout applicator's applicator surface component 1 into the grout, ensuring the surface is evenly coated. The operator holds the applicator handle component 2 and moves the applicator to the vicinity of the wall surface to be grouted.

[0055] 3. Pulping Operation: During the pulverizing operation, the operator holds the pulverizing handle assembly 2 and pulls the traction component 42 appropriately. This action causes the elastic component 41 to undergo compression deformation, storing elastic potential energy. At this time, the distance between the pulverizing surface assembly 1 and the pulverizing surface support assembly 3 is shortened, but it has not yet come into contact with the wall surface.

[0056] Immediately afterwards, the operator quickly released the traction component 42. Due to the previously stored elastic potential energy, the elastic component 41 began to release, propelling the striking surface assembly 1 rapidly toward the wall. During this process, the rebound force of the elastic component 41 and the inertial force of the striking surface assembly 1 worked together, causing the striking surface assembly 1 to impact the wall with a certain speed and force.

[0057] When the slurry assembly 1 comes into contact with the wall, an adhesive force is generated between the slurry on the slurry assembly and the wall. At this time, the rebound force of the elastic element 41 continues to act, attempting to pull the slurry assembly 1 away from the wall. However, due to the presence of the adhesive force, the slurry assembly 1 will remain on the wall for a period of time, during which time the slurry is evenly applied to the wall.

[0058] As the rebound force of the elastic element 41 gradually weakens, the patting assembly 1 begins to separate from the wall. During the separation process, the patting assembly 1 may continue to move a short distance away from the wall due to inertia until the elastic element 41 completely returns to its undeformed state, completing the patting action.

[0059] During the grouting process, ensure that the grouting assembly 1 is at an appropriate angle to the wall surface so that the grout is evenly distributed on the wall surface, forming an ideal friction surface. After grouting is completed, the elastic element 41 returns to its original position under the rebound action, ready for the next grouting action.

[0060] Repeat the above steps until the entire wall surface is evenly covered with grout.

[0061] 4. Inspection and Adjustment: During the grouting process, the coverage of the grout on the wall surface should be checked frequently to ensure that there are no omissions or excessive accumulations. If uneven grout distribution or hollow areas are found, adjustments and remedies should be made promptly.

[0062] The slurry-patting paddle achieves automatic reciprocating motion of the slurry-patting assembly 1 through the coordinated action of the elastic element 41 and the traction element 42 in the slurry-patting drive component. The operator only needs to hold the paddle arm assembly 2 and pull or release the traction element 42 at the appropriate time to control the slurry-patting assembly 1 to move closer to or away from the wall for slurry-patting operations. This fundamentally solves the problem of traditional slurry-patting paddles requiring repeated manual swinging and greatly improves the automation level of slurry-patting operations.

[0063] Meanwhile, with the introduction of the slurry-driving component, operators no longer need to rely on arm strength to repeatedly swing the slurry-driving board, thus significantly reducing physical exertion and the risk of arm injury. The elastic rebound characteristic of the slurry-driving component allows the slurry-driving component 1 to automatically move away from and towards the slurry-driving support component 3 after the traction effect disappears, thereby achieving continuous and uniform slurry-driving action. This automated slurry-driving method not only improves work efficiency but also ensures the uniformity and consistency of the wall slurry coverage, enhancing the quality of the plastering project.

[0064] In this preferred embodiment, the paddle support component 3 has a cross-shaped structure, which not only enhances the structural stability of the paddle but also provides a suitable platform for the interaction between the paddle component 1 and the elastic element 41. Figure 2 As shown, sufficient space is reserved between the patting support assembly 3 and the patting assembly 1 to allow the elastic element 41 to compress and rebound. When the operator pulls the traction component 42, the elastic element 41 can be smoothly compressed within the reserved space, storing energy. When the traction component is released, the elastic element can rebound quickly, pushing the patting assembly 1 to impact the wall with a certain speed and force, achieving efficient patting operation.

[0065] In this preferred embodiment, the elastic element 41 is a spring, and there are four springs evenly distributed on the cross-shaped paddle support assembly 3. The springs have excellent rebound performance; during the paddle operation, the springs can quickly rebound after being compressed, providing a stable rebound force to the paddle assembly 1. The even distribution of the four springs ensures that the paddle assembly 1 can rebound evenly and stably when subjected to external forces, helping the paddle assembly maintain a smooth movement trajectory during the paddle process, avoiding skewing or shaking, thereby improving the uniformity and quality of the paddle.

[0066] like Figure 1 and Figure 2 As shown, the paddle drive assembly also includes a guide assembly, and the traction member 42 is connected to the guide assembly. The guide assembly is used to limit the distribution of the traction member 42 along the length direction of the paddle assembly 2.

[0067] The guide assembly provides a stable movement path for the traction component 42, ensuring the smoothness and accuracy of the traction component during the pulling and releasing process. This helps to reduce uneven slurry application caused by swaying or offset of the traction component, and improves the quality of the slurry application operation.

[0068] In this preferred embodiment, the drumstick assembly 2 has a hollow structure, which not only reduces the overall weight but also makes the entire drumstick structure more compact, facilitating prolonged hand-held operation by construction workers, reducing arm and shoulder fatigue, and improving work efficiency. The guide assembly and traction component 42 are built into the drumstick assembly 2, effectively preventing damage to these critical components from the external environment. Furthermore, construction workers do not need to search for or adjust these components externally; they can control the movement of the drumstick with simple operations, reducing external interference and allowing for more focused and efficient drumsticking operations.

[0069] like Figure 1 and Figure 2As shown, the guide assembly includes a guide shaft 431 and a lifting ring 432. The guide shaft 431 is mounted on the racket face support assembly 3, and the lifting ring 432 is mounted on the racket shaft assembly 2 at the end away from the racket face support assembly 3. The traction member 42 is set on the racket shaft assembly 2 through the guide shaft 431 and the lifting ring 432 respectively, and one end of the traction member 42 passes around the guide shaft 431 and is connected to the racket face assembly 1.

[0070] The guide shaft 431 is mounted on the paddle support assembly 3, providing a defined movement path for the traction member 42. When the traction member 42 is pulled or released, it moves smoothly along the guide shaft 431, ensuring that the paddle assembly 1 can perform the paddle operation along a predetermined trajectory. This design reduces the swaying and offset of the traction member 42, improving the accuracy and uniformity of the paddle operation.

[0071] The lifting ring 432 is installed at the end of the paddle assembly 2 away from the paddle support assembly 3, providing a stable support point for the other end of the traction member 42. This helps to balance the tension of the traction member 42 and prevents the paddle assembly from shaking or deviating from the target position due to uneven tension. Therefore, the paddle operation is more stable and reliable.

[0072] Through the cooperation of the guide shaft 431 and the lifting ring 432, the traction component 42 can be easily installed and removed from the paddle assembly 2, simplifying the operation process for operators and reducing installation and debugging time.

[0073] like Figure 1 As shown, a rope hole is formed in the center of the racket face support assembly 3, and the guide shaft 431 is arranged on the rope hole in the radial direction along the rope hole.

[0074] In this preferred embodiment, the guide shaft 431 and the lifting ring 432 are made of wear-resistant and corrosion-resistant materials, which can withstand friction and tension during long-term use, thereby extending the service life of the guide assembly and reducing downtime and maintenance costs caused by component damage.

[0075] like Figure 1 and Figure 3 As shown, the paddle driving assembly also includes a switch 44, which is mounted on the paddle arm assembly 2 and located between the guide shaft 431 and the lifting ring 432; the other end of the traction member 42 passes around the lifting ring 432 and folds back to connect with the switch 44, and the switch 44 is used to pull the traction member 42.

[0076] The addition of switch 44 allows operators to more easily control the pulling and releasing of the traction component 42. By simply operating switch 44, rapid tamping of the tamping assembly 1 can be achieved without manually pulling or releasing the traction component 42, greatly improving operational convenience. Simultaneously, switch 44 enables more precise control of the traction component 42 to regulate the rhythm and intensity of tamping. Operators can adjust the frequency and intensity of tamping by operating the switch quickly or slowly as needed, thereby achieving more efficient tamping operations.

[0077] like Figure 1 and Figure 2 As shown, the traction component 42 includes a first traction rope 421 and a second traction rope 422. The first traction rope 421 is connected to the second traction rope 422. One end of the second traction rope 422 passes around the hanging ring 432 and turns back to connect with the switch 44. One end of the first traction rope 421 passes around the guide shaft 431 and connects with the beater assembly 1.

[0078] This embodiment divides the traction component 42 into two parts, allowing for more precise control over the distribution of traction force. The first traction rope 421 is responsible for pulling the patting assembly 1 toward or away from the wall, while the second traction rope 422 controls the start and stop of the entire traction action via the switch 44, enabling the operator to more accurately control the force and rhythm of the patting.

[0079] In this embodiment, the first traction rope 421 is a rigid rope, and the second traction rope 422 is an elastic rope. The rigid rope has extremely high tensile strength and wear resistance, enabling the first traction rope 421 to withstand large traction forces and making it less prone to breakage or wear, thereby ensuring the stability and durability of the slurry-patching operation. The elastic rope has good elasticity, which can provide a cushioning effect during traction, helping to reduce the impact force when the slurry assembly 1 hits the wall, protecting the wall from damage, and improving the comfort of the operator.

[0080] like Figure 1 and Figure 2 As shown, the switch 44 includes a button 441 and a hook 442. The hook 442 is rotatably mounted on the racket arm assembly 2. The button 441 abuts against one end of the hook 442. The button 441 is used to push the other end of the hook 442 to rotate in a direction away from the hanging ring 432. The other end of the hook 442 is connected to one end of the second traction rope 422. When the hook 442 rotates in a direction away from the hanging ring 432, the hook 442 can pull the second traction rope 422 to move, thereby driving the first traction rope 421, so that the racket face assembly 1 can approach the racket face support assembly 3 under the pulling action of the first traction rope 421.

[0081] The combination of button 441 and hook 442 makes operation simpler and more intuitive. The operator only needs to press button 441 to move the traction component 42 by rotating hook 442, thereby reducing the difficulty of operation and improving work efficiency.

[0082] In this embodiment, the hook 442 serves as a transmission component, and its rotation can efficiently move the second traction rope 422. Due to the good elasticity of the elastic rope, the rotation of the hook 442 can be quickly converted into traction force, which in turn drives the first traction rope 421 (rigid rope) to enable the racket face assembly to respond quickly.

[0083] like Figure 4 As shown, the paddle assembly 1 includes a paddle plate 11 and an outer frame 12, with the outer frame 12 fixed around the paddle plate 11; the paddle support assembly 3 is mounted on the outer frame 12, allowing the paddle arm assembly 2 to be connected to the paddle assembly 1 via the paddle support assembly 3; one end of the traction member 42 passes through the paddle support assembly 3 and is connected to the paddle plate 11, allowing the paddle plate 11 to move closer to the paddle support assembly 3 under the pulling action of the traction member 42; and the elastic member 41 is supported between the paddle plate 11 and the paddle support assembly 3.

[0084] The outer frame 12 is fixed around the slurry-beating plate 11, enhancing the overall structural stability of the slurry-beating assembly 1 and enabling the slurry-beating plate 11 to withstand greater impact forces during slurry-beating without easily deforming or being damaged. The slurry-beating support assembly 3 is mounted on the outer frame 12, providing a stable support point for the connection between the slurry-beating arm assembly 2 and the slurry-beating assembly 1, ensuring that the traction force can be transmitted evenly and stably to the slurry-beating plate 11, thereby improving the accuracy and stability of the slurry-beating operation.

[0085] In this embodiment, the slurry-applying plate 11 has a mesh structure, which allows materials such as mud or plaster to penetrate the mesh better. At the same time, the mesh structure enables the slurry-applying plate 11 to form more uniform burrs or protrusions during the slurry-applying process, thereby increasing the roughness and adhesion area of ​​the wall surface and helping to reduce quality problems such as hollowness and peeling.

[0086] In this embodiment, the slurry board 11 is made of plastic material. Because plastic material is lightweight and high-strength, the slurry board is lighter and easier for operators to carry and use while ensuring strength.

[0087] In this preferred embodiment, the slurry application assembly 1 further includes steel wire ropes 13 and limiting edges 14. The steel wire ropes 13 are distributed in a mesh pattern on the slurry application plate 11, and the limiting edges 14 are installed around the steel wire ropes 13 and are fixedly connected to the outer frame 12. The mesh structure of the steel wire ropes 13 helps to form a more uniform slurry surface during the slurry application process. When materials such as mud or plaster are applied to the slurry application plate, they pass through the mesh of the steel wire ropes 13 and adhere to the wall surface, thereby forming a more uniform and delicate coating. The limiting edges 14 are installed around the steel wire ropes 13 and are fixedly connected to the outer frame 12, forming a closed boundary, which helps to prevent material from overflowing from the edge of the slurry application plate 11 during the slurry application process, thereby maintaining the cleanliness of the construction site and saving materials.

[0088] like Figure 2 and Figure 4 As shown, it also includes a movable component 5, which is installed on the side of the outer frame 12 away from the racket face support component 3. The movable component 5 is used to abut against the wall and drive the racket face component 1 to move.

[0089] The movable component 5 can be directly attached to the wall surface, and the entire trowel assembly 1 can be easily moved along the wall by pushing or pulling by the operator. This greatly simplifies the construction operation, reduces the time and physical effort required to manually move the trowel, and thus improves construction efficiency.

[0090] like Figure 2 and Figure 4 As shown, the moving component 5 includes at least four balls 51, each ball 51 being rotatably mounted on the outer frame 12, and the balls 51 being evenly distributed.

[0091] The ball bearings 51 on the outer frame 12 enable the patting assembly 1 to move closely and smoothly against the wall surface, which not only reduces bumps and pauses during movement, but also ensures the continuity and smoothness of the patting operation, thereby improving the overall construction efficiency.

[0092] At the same time, the ball bearings can significantly reduce the movement resistance of the tamper assembly 1 on the wall, making it easier for operators to push or pull the tamper assembly 1 to carry out operations, reducing physical exertion and time waste, and further improving construction efficiency.

[0093] like Figure 1 and Figure 2 As shown, it also includes a rotating component 6, and the racket face support component 3 is rotatably connected to the racket shaft component 2 through the rotating component 6.

[0094] The rotating component 6 allows the patting support component 3 to rotate relative to the patting rod component 2, enabling the operator to adjust the angle and position of the patting component 1 as needed. This flexibility not only improves construction efficiency but also allows the patting operation to more precisely cover every corner of the wall and hard-to-reach areas.

[0095] In this embodiment, the rotating assembly 6 includes two movable bolts 61. A first through hole is formed on the patting surface support assembly 3, and a second through hole is formed on the patting rod assembly 2. Each movable bolt 61 can pass through the first and second through holes to rotatably connect the patting surface support assembly 3 to the rotating assembly 6. The movable bolts 61 allow the patting surface support assembly 3 to rotate relative to the patting rod assembly 2 to a certain extent. This flexibility allows the operator to easily adjust the angle of the patting surface according to construction needs, thereby better controlling the distribution and uniformity of the slurry material.

[0096] Although the movable bolts 61 provide rotational functionality, they also ensure connection stability through a tight fit in the through-hole, while preventing the paddle support assembly 3 from accidentally falling off or loosening during construction, thus guaranteeing the safety and reliability of the construction process. If the movable bolts 61 or related components become worn or damaged, operators can easily disassemble and replace them to extend the service life of the paddle and reduce maintenance costs.
