Description

Technical Field

[0001] This invention relates to the field of building material construction technology, specifically to a self-leveling gypsum construction device and its construction method. Background Technology

[0002] The construction method for self-leveling floors involves using materials with self-leveling or slightly assisted leveling functions on a base layer, mixing them on-site, and then spreading them to form the surface layer. Common types of self-leveling floors include clay-based self-leveling floors, resin-based self-leveling floors, and resin-cement composite mortar self-leveling floors. Self-leveling flooring projects offer aesthetically pleasing surface coatings, high cleanliness, high wear resistance, and load-bearing capacity. Most importantly, they provide an attractive decorative effect, as the first visual impression is based on the surface color and finish.

[0003] When pouring gypsum-based self-leveling compound, a mixer is needed to mix the gypsum-based self-leveling material with water in advance, and then transport it to the ground through pipes, or the mixer is pushed to pour the gypsum-based self-leveling compound. After the gypsum-based self-leveling compound is poured, it needs to be manually leveled, which results in low construction efficiency. Summary of the Invention

The top end of the stirring shaft extends out of the storage box and is located on the outer side of the storage box and connected to the first drive assembly.

[0014] Preferably, the first drive assembly includes a first connecting shaft, which is fixedly connected to the middle of the upper end face of the second gear, and the top end of the first connecting shaft is connected to the stirring shaft via a belt assembly.

[0015] Preferably, the second drive assembly includes a half-bevel gear, which is fixedly connected to the lower side of the second gear. A threaded sleeve shaft is rotatably connected to the middle of the piston seat on the side away from the second one-way valve. A threaded rod is threadedly connected inside the threaded sleeve shaft. One end of the threaded rod is fixedly connected to one side of the piston block. One end of the threaded sleeve shaft extends out of the piston seat. A first bevel gear and a second bevel gear are fixedly connected to the outer section of the threaded sleeve shaft located on the piston seat. The half-bevel gear meshes with the first bevel gear and the second bevel gear respectively.

[0016] Preferably, the third drive assembly includes a second connecting shaft, one end of which is fixedly connected to the middle of the first gear, and the other end of which is provided with a spline groove, into which a spline shaft is inserted, and one end of which is connected to a smoothing mechanism.

[0017] Preferably, the smoothing mechanism includes a mounting plate, which is movably mounted on the lower side of the moving mechanism. A first connecting rod is rotatably connected to the bottom side of the mounting plate. One end of the spline shaft is fixedly connected to one end of the first connecting rod.

[0018] Preferably, the device further includes an adjustment mechanism for adjusting the height of the smoothing mechanism to achieve smoothing of different thicknesses.

One end of the bidirectional screw extends out of the fixed base, and a rotating wheel is fixedly connected to the outer end of the bidirectional screw.

[0019] This invention provides a construction method using the above-described device, comprising the following steps:

[0020] S1. First, the gypsum slurry raw material is put into the storage box through the inlet of the storage box, and the laying construction is carried out by pushing the device with the push handle and casters.

[0021] S2. When laying, start the motor, and drive the first gear to rotate through the motor output. The rotation of the first gear drives the second gear to rotate. At the same time, the rotation of the second gear drives the storage box to rotate through the first connecting shaft and belt assembly, so as to stir the gypsum slurry raw material in the storage box.

[0022] S3. While the second gear rotates, it drives the half-bevel gear to rotate. When the half-bevel gear rotates and meshes with the second bevel gear, it drives the screw sleeve shaft to rotate in the forward direction. This drives the threaded rod through the screw sleeve shaft, causing the threaded rod to retract into the screw sleeve shaft. This causes the piston block to slide away from the second one-way valve, and then the gypsum slurry in the storage box is drawn into the piston seat through negative pressure. When the half-bevel gear rotates and meshes with the first bevel gear, it drives the screw sleeve shaft to rotate in the reverse direction. This drives the threaded rod through the screw sleeve shaft, causing the threaded rod to extend out from the screw sleeve shaft. This causes the piston block to slide closer to the second one-way valve, and then the gypsum slurry drawn from the storage box in the piston seat flows out through the discharge head.

[0023] S4. While the first gear rotates, the third drive assembly drives the first connecting rod to rotate along the spline shaft, thereby driving the second connecting rods on both sides to move. At the same time, the rocker arm swings along its hinge end with the mounting plate, thereby driving the swing seat and scraper to swing, so as to achieve the smoothing of the gypsum mortar. In addition, the limit rod limits its swing stroke during its swinging process, so as to realize the construction of gypsum mortar.

[0024] Preferably, before construction, the rotating wheel can drive the bidirectional screw to rotate, thereby causing the two sliders to move closer or further apart, which in turn drives the mounting plate to move and adjust the height of the mounting plate, so as to adjust the height of the smoothing mechanism and achieve smoothing operations of different thicknesses.

[0025] This invention provides a self-leveling plaster application device and method. It offers the following advantages:

[0026] This invention, through the automated operation and coordination of the device, enables efficient mixing, quantitative dispensing, and smoothing of gypsum mortar, thereby accelerating construction speed. The mixing component ensures the uniformity of the gypsum mortar, maintaining consistent mortar quality throughout the construction process. The quantitative dispensing mechanism ensures precise dispensing of gypsum mortar each time, helping to reduce waste and improve construction efficiency. The smoothing mechanism precisely smooths out the flowing gypsum mortar, ensuring the flatness and quality of the construction surface. In summary, the automation function of the device reduces the need for manual operation, thereby lowering labor costs and improving construction efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see the appendix Figure 1 - Appendix Figure 6 This invention provides a self-leveling plaster application device, comprising:

[0036] The moving mechanism 10, which supports the entire device, can move and drive the entire device to move within the working area;

[0037] The storage mechanism 20 is used to store gypsum mortar. The storage mechanism 20 is located on the upper side of the moving mechanism 10. The storage mechanism 20 is equipped with a stirring component inside, which is used to stir the gypsum mortar to maintain its uniformity.

[0038] The quantitative feeding mechanism 30 is used to quantitatively feed the gypsum mortar stored in the storage mechanism 20. The quantitative feeding mechanism 30 includes a piston seat 31, which is connected to the storage mechanism 20 through a first one-way valve 32. A discharge head 34 is connected to one side of the piston seat 31 through a second one-way valve 33. A piston block 35 is slidably connected to the inner cavity of the piston seat 31.

[0039] Drive mechanism 40 is used for the coordinated drive of the entire device;

[0040] The smoothing mechanism 50 is used to smooth the gypsum mortar flowing out through the discharge head 34. The smoothing mechanism 50 is located on the bottom side of the moving mechanism 10.

[0041] In this embodiment, the automated operation and coordination of the device enable efficient mixing, quantitative feeding, and smoothing of gypsum mortar, thereby accelerating construction speed. The mixing component ensures the uniformity of the gypsum mortar, maintaining consistent mortar quality throughout the construction process. The quantitative feeding mechanism 30 ensures precise feeding of gypsum mortar each time, reducing waste and improving construction efficiency. The smoothing mechanism 50 precisely smooths the flowing gypsum mortar, ensuring the flatness and quality of the construction surface. Overall, the device's automation reduces the need for manual operation, thereby lowering labor costs and improving construction efficiency.

[0042] In one embodiment, the moving mechanism 10 includes a support platform 11, a plurality of casters 12 are fixedly connected to the bottom side of the support platform 11, a push handle 13 is fixedly connected to one side of the support platform 11, and a piston seat 31 is fixedly connected to the upper side of the support platform 11.

[0043] In this embodiment, the device is mobile and operable, supporting free movement within the construction area. Operators can control the direction and speed of movement via the push handle 13, making the device easier to operate and control during construction, thereby improving work efficiency and accuracy.

[0044] In one embodiment, the storage mechanism 20 includes a storage box 21, which is fixedly connected to the upper side of the piston seat 31. The storage box 21 and the piston seat 31 are connected by a first one-way valve 32. The stirring assembly is disposed inside the storage box 21. The stirring assembly includes a stirring shaft 22 and a stirring rod 23. The stirring shaft 22 is rotatably connected to the middle of the storage box 21, and the stirring rod 23 is fixedly connected to the outer wall of the storage box 21. The top end of the stirring shaft 22 extends out of the storage box 21 and is located on the outer side of the storage box 21 and connected to the first drive assembly 44.

[0045] In this embodiment, the storage mechanism 20 can store and stir gypsum mortar to ensure the uniformity and fluidity of the mortar. The setting of the stirring shaft 22 allows the stirring operation to be controlled from outside the storage box 21, which helps to simplify the design and operation and provides a better stirring effect.

[0046] In one embodiment, the drive mechanism 40 includes a motor 41, which is fixedly connected to the upper side of the moving mechanism 10. A first gear 42 is fixedly connected to the output end of the motor 41. A second gear 43 is meshed with the first gear 42. One side of the second gear 43 is connected to the stirring assembly through the first drive assembly 44 to drive the stirring assembly to move.

[0047] Furthermore, the first drive assembly 44 includes a first connecting shaft 441, which is fixedly connected to the middle of the upper end face of the second gear 43, and the top end of the first connecting shaft 441 is connected to the stirring shaft 22 through a belt assembly 442.

[0048] In this embodiment, the motor 41 is started during laying, and the output of the motor 41 drives the first gear 42 to rotate. The rotation of the first gear 42 drives the second gear 43 to rotate. At the same time, the rotation of the second gear 43 drives the storage box 21 to rotate through the first connecting shaft 441 and the belt assembly 442, so as to stir the gypsum slurry raw material in the storage box 21 and stir the gypsum mortar to maintain its uniformity.

[0049] In one embodiment, one side of the second gear 43 is connected to the piston block 35 via the second drive assembly 45 to drive the piston block 35 to cooperate with the first one-way valve 32 and the second one-way valve 33 for quantitative feeding;

[0050] Furthermore, the second drive assembly 45 includes a half-bevel gear 451, which is fixedly connected to the lower side of the second gear 43. A threaded sleeve shaft 37 is rotatably connected to the middle of the piston seat 31 on the side away from the second one-way valve 33. A threaded rod 36 is threadedly connected inside the threaded sleeve shaft 37. One end of the threaded rod 36 is fixedly connected to one side of the piston block 35. One end of the threaded sleeve shaft 37 extends out of the piston seat 31. The first bevel gear 452 and the second bevel gear 453 are fixedly connected to the outer section of the threaded sleeve shaft 37 located on the piston seat 31. The half-bevel gear 451 meshes with the first bevel gear 452 and the second bevel gear 453 respectively.

[0051] In this embodiment, while the second gear 43 rotates, it drives the half-bevel gear 451 to rotate. When the half-bevel gear 451 rotates and meshes with the second bevel gear 453, it drives the threaded sleeve shaft 37 to rotate forward. This drives the threaded rod 36 to retract into the threaded sleeve shaft 37, thereby causing the piston block 35 to slide away from the second one-way valve 33. Then, through negative pressure, the gypsum slurry in the storage tank 21 is drawn into the piston seat 31. When the half-bevel gear 451 rotates and meshes with the first bevel gear 452, it drives the threaded sleeve shaft 37 to rotate in reverse. This drives the threaded rod 36 to extend out from the threaded sleeve shaft 37, thereby causing the piston block 35 to slide closer to the second one-way valve 33. Then, the gypsum slurry drawn from the storage tank 21 in the piston seat 31 flows out through the discharge head 34. This achieves quantitative feeding of gypsum slurry, ensuring that the amount of gypsum mortar fed each time is accurate. This helps to reduce waste and improve construction efficiency.

[0052] In one embodiment, one side of the first gear 42 is connected to the smoothing mechanism 50 via a third drive assembly 46 to drive the smoothing mechanism 50 to perform a smoothing operation.

[0053] Furthermore, the third drive assembly 46 includes a second connecting shaft 461, one end of which is fixedly connected to the middle of the first gear 42, and the other end of the second connecting shaft 461 is provided with a spline groove 462, in which a spline shaft 463 is inserted, and one end of the spline shaft 463 is connected to the smoothing mechanism 50.

[0054] Furthermore, the smoothing mechanism 50 includes a mounting plate 51, which is movably mounted on the lower side of the moving mechanism 10. A first connecting rod 52 is rotatably connected to the bottom side of the mounting plate 51. One end of the spline shaft 463 is fixedly connected to one end of the first connecting rod 52. Two second connecting rods 53 are rotatably connected to the end of the first connecting rod 52 away from the spline shaft 463. The two second connecting rods 53 are arranged opposite to each other. A rocker arm 54 is rotatably connected to the end of each of the two second connecting rods 53 away from the first connecting rod 52. One side of the rocker arm 54 is hinged to one side of the mounting plate 51. A swing seat 55 is rotatably connected to the end of each rocker arm 54 away from the second connecting rod 53. A scraper 56 is fixedly connected to one side of each swing seat 55. A limit rod 57 is hinged to one side of the mounting plate 51. One end of the limit rod 57 is hinged to one side of the swing seat 55.

[0055] In this embodiment, while the first gear 42 rotates, the third drive assembly 46 drives the first connecting rod 52 to rotate along the spline shaft 463, thereby driving the second connecting rods 53 on both sides to move. At the same time, the rocker arm 54 swings along its hinge end with the mounting plate 51, thereby driving the swing seat 55 and scraper 56 to swing, so as to achieve the smoothing of the gypsum mortar. In addition, the limiting rod 57 limits the swing stroke during its swinging process to realize the construction of gypsum mortar.

[0056] In one embodiment, the device further includes an adjustment mechanism 60, which is used to adjust the height of the smoothing mechanism 50 to achieve smoothing of different thicknesses. The adjustment mechanism 60 includes a fixed base 61, which is fixedly connected to the lower side of the moving mechanism 10. A bidirectional screw 62 is rotatably connected to the middle of the fixed base 61. A slider 63 is threadedly connected to the threaded outer wall of both sides of the bidirectional screw 62. A hinge rod 64 is rotatably connected to one side of each slider 63. One end of each of the two hinge rods 64 is hinged to the upper side of the mounting plate 51. One end of the bidirectional screw 62 extends out of the fixed base 61. A wheel 65 is fixedly connected to the outer end of the bidirectional screw 62 located on the fixed base 61.

[0057] In this embodiment, before construction, the rotating wheel 65 can drive the bidirectional screw 62 to rotate, thereby causing the two sliders 63 to move closer or further apart, thereby causing the mounting plate 51 to move and adjust the height of the mounting plate 51, so as to adjust the height of the smoothing mechanism 50 and achieve smoothing operations of different thicknesses.

[0058] This invention provides a construction method using the above-described device, comprising the following steps:

[0059] S1. Before construction, depending on the required slurry thickness, the rotating wheel 65 drives the bidirectional screw 62 to rotate, thereby causing the two sliders 63 to move closer or further apart, which in turn drives the mounting plate 51 to move. Adjusting the height of the mounting plate 51 allows for adjusting the height of the smoothing mechanism 50, thus enabling smoothing operations of different thicknesses.

[0060] S2. First, the gypsum slurry raw material is put into the storage box 21 through the inlet of the storage box 21, and the paving construction is carried out by the pusher 13 and the universal wheel 12 in conjunction with the pusher.

[0061] S3. When laying, start the motor 41. The output of the motor 41 drives the first gear 42 to rotate. The rotation of the first gear 42 drives the second gear 43 to rotate. At the same time, the rotation of the second gear 43 drives the storage box 21 to rotate through the first connecting shaft 441 and the belt assembly 442, so as to stir the gypsum slurry raw material in the storage box 21.

[0062] S4. While the second gear 43 rotates, it drives the half-bevel gear 451 to rotate. When the half-bevel gear 451 rotates and meshes with the second bevel gear 453, it drives the threaded sleeve shaft 37 to rotate in the forward direction. This drives the threaded rod 36 through the threaded sleeve shaft 37, causing the threaded rod 36 to retract into the threaded sleeve shaft 37. This causes the piston block 35 to slide away from the second one-way valve 33, and then the gypsum slurry in the storage box 21 is drawn into the piston seat 31 through negative pressure. When the half-bevel gear 451 rotates and meshes with the first bevel gear 452, it drives the threaded sleeve shaft 37 to rotate in the reverse direction. This drives the threaded rod 36 through the threaded sleeve shaft 37, causing the threaded rod 36 to extend out from the threaded sleeve shaft 37. This causes the piston block 35 to slide closer to the second one-way valve 33, and then the gypsum slurry drawn from the storage box 21 in the piston seat 31 flows out through the discharge head 34.

[0063] S5. While the first gear 42 rotates, the third drive assembly 46 drives the first connecting rod 52 to rotate along the spline shaft 463, thereby driving the second connecting rods 53 on both sides to move. At the same time, the rocker arm 54 swings along its hinge end with the mounting plate 51, thereby driving the swing seat 55 and scraper 56 to swing, so as to achieve the smoothing of the gypsum mortar. In addition, the limit rod 57 limits the swing stroke during its swing, so as to realize the construction of gypsum mortar.

[0064] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

2. The construction method of the self-leveling gypsum board construction device according to claim 1, characterized in that, Includes the following steps: S1. First, the gypsum slurry raw material is put into the storage box (21) through the inlet of the storage box (21), and the paving construction is carried out by the push handle (13) and the universal wheel (12) in conjunction with the push device. S2. When laying, start the motor (41), and drive the first gear (42) to rotate through the output of the motor (41). The rotation of the first gear (42) drives the second gear (43) to rotate. At the same time, the rotation of the second gear (43) drives the storage box (21) to rotate through the first connecting shaft (441) and the belt assembly (442) to stir the gypsum slurry raw material in the storage box (21). S3. While the second gear (43) rotates, it drives the half-bevel gear (451) to rotate. When the half-bevel gear (451) rotates and meshes with the second bevel gear (453), it drives the threaded sleeve shaft (37) to rotate in the forward direction. This drives the threaded rod (36) through the threaded sleeve shaft (37), causing the threaded rod (36) to retract into the threaded sleeve shaft (37). This causes the piston block (35) to slide away from the second one-way valve (33), and then the negative pressure pushes the gypsum in the storage box (21) to... The slurry is drawn into the piston seat (31); when the half bevel gear (451) rotates and meshes with the first bevel gear (452), it drives the screw sleeve shaft (37) to reverse, thereby driving the threaded rod (36) through the screw sleeve shaft (37), so that the threaded rod (36) extends out from the screw sleeve shaft (37), thereby driving the piston block (35) to slide close to the second one-way valve (33), and then the gypsum slurry drawn from the storage box (21) in the piston seat (31) flows out through the discharge head (34); S4. While the first gear (42) rotates, the third drive assembly (46) drives the first connecting rod (52) to rotate along the spline shaft (463), thereby driving the second connecting rods (53) on both sides to move. At the same time, the rocker arm (54) swings along its hinge end with the mounting plate (51), thereby driving the swing seat (55) and scraper (56) to swing, so as to achieve the smoothing of the gypsum mortar. In addition, the limit rod (57) limits its swing stroke during its swing, so as to achieve the construction of gypsum mortar.

3. The construction method according to claim 2, characterized in that, Before construction, the rotating wheel (65) can drive the bidirectional screw (62) to rotate, thereby causing the two sliders (63) to move closer or further apart, thereby causing the mounting plate (51) to move and adjust the height of the mounting plate (51) to adjust the height of the smoothing mechanism (50) to achieve smoothing operations of different thicknesses.
