Description

Technical Field

[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0038] Reference Figures 1 to 3 As shown, this utility model discloses a ground leveling device, characterized in that it includes: a leveling component 1, which includes a mounting base 11, a pressure roller 14, a first driving member 141, and a feeding mechanism. The pressure roller 14 is rotatably connected to the mounting base 11, the output end of the first driving member 141 is connected to the pressure roller 14, and the feeding mechanism is connected to the mounting base 11; and a movable component, which is connected to the leveling component 1 and is capable of driving the leveling component 1 to move.

[0039] In this embodiment, a ground leveling device is provided. The movable component drives the leveling component 1 to move. During the movement of the leveling component 1, the feeding mechanism is used to transport cement, so that the cement on the ground is located close to the cement leveling reference surface. The first driving component 141 drives the pressure roller 14 to rotate, so that the pressure roller 14 squeezes and levels the cement during the rotation. Through the feeding mechanism and the pressure roller 14, the cement is leveled twice, and the pressure roller 14 can move while maintaining the cement leveling reference surface, thereby improving the horizontal accuracy of the cement ground leveling.

[0040] Reference Figure 3 and Figure 4As shown, the leveling assembly 1 is used to level a cement floor. The leveling assembly 1 includes a mounting base 11, a pressure roller 14, a first driving component 141, and a feeding mechanism. The mounting base 11 includes a support plate 112 and two parallel and oppositely arranged mounting plates 111. The two mounting plates 111 are respectively connected to both ends of the support plate 112. Both ends of the pressure roller 14 are rotatably connected to the mounting plates 111, and the pressure roller 14 is located below the support plate 112, thus allowing the pressure roller 14 to be rotatably connected to the mounting base 11. The first driving component 141 is a rotary driving component; specifically, the first driving component 141 can be considered as a rotary motor. The first driving component 141 is connected to the mounting base 11, and its output end is connected to the pressure roller 14, thereby enabling the first driving component 141 to drive the pressure roller 14 to rotate. Preferably, the mounting plate 111 has a waist-shaped mounting hole arranged vertically, and both ends of the pressure roller 14 pass through the mounting hole. The two ends of the pressure roller 14 are connected to the mounting plate 111 through the first adjusting member. The mounting plate 111 has multiple connecting holes arranged vertically. The pressure roller 14 is connected to the connecting holes at different positions through the first adjusting member, so that the ends of the pressure roller 14 can be located at different positions of the mounting hole, thereby adjusting the height of the pressure roller 14 so that the pressure roller 14 can be adjusted according to the height of the cement leveling reference surface.

[0041] The feeding mechanism is connected to the mounting base 11. Specifically, the feeding mechanism includes a first feeding component 12, which includes a rotating shaft 15 and a feeding plate 16. The feeding plate 16 is connected to the rotating shaft 15 and extends spirally along the axial direction of the rotating shaft 15 to form a receiving space. The rotating shaft 15 is rotatably connected to the mounting plate 111 of the mounting base 11. The central axis of the rotating shaft 15 is parallel to the central axis of the pressure roller 14. The output end of the first driving component 141 is connected to the rotating shaft 15 through a gear or chain, thereby enabling the first driving component 141 to drive the rotating shaft 15 to rotate. During the process of the first driving component 141 driving the first feeding component 12 to rotate and the leveling assembly 1 to move, the cement at the thicker position on the ground can enter the receiving space of the first feeding component 12. The rotation of the first feeding component 12 causes the cement located in the receiving space to move away from the moving path of the leveling assembly 1. In another embodiment, the pressure roller 14 and the rotating shaft 15 can be driven by two driving members respectively, so that the rotation speed of the first feeding member 12 and the pressure roller 14 can be adjusted independently.

[0042] Reference Figure 5As shown, the first feeding component 12 also includes a feeding plate 13, which is connected to the mounting base 11. The feeding plate 13 is arc-shaped and forms a feeding space. The feeding end 131 of the feeding plate 13 is provided with a guide surface, that is, the thickness of the feeding end 131 of the feeding plate 13 gradually decreases towards the end face, and the feeding end 131 of the feeding plate 13 extends away from the pressure roller 14. The rotating shaft 15 is located within the feeding space, and the height of the feeding end 131 of the feeding plate 13 is higher than the height of the pressing position of the pressure roller 14. Specifically, the feeding end 131 of the feeding plate 13 is located at the edge of the feeding plate 13 away from the mounting base 11, and the height of the feeding end 131 of the feeding plate 13 is the distance between the feeding end 131 of the feeding plate 13 and the unpaved cement floor. The pressing position of the pressure roller 14 is the bottom position of the pressure roller 14 used to contact the cement, and the height of the pressing position of the pressure roller 14 is the distance between the pressing position and the unpaved cement floor. That is, there is a certain distance between the feeding end 131 of the feeding plate 13 and the cement leveling reference surface, and the pressure roller 14 is in contact with the cement leveling reference surface. In this embodiment, the height difference between the feeding end 131 of the feeding plate 13 and the pressing position of the pressure roller 14 is 1 mm to 6 mm. As the first feeding component 12 rotates and the leveling component 1 moves, the cement at a thicker position on the ground can enter the feeding space, and then the cement enters the receiving space of the first feeding component 12. The feeding plate 13 can perform the first leveling of the cement, and then the pressure roller 14 performs a second leveling of the cement with higher precision.

[0043] Reference Figure 6 and Figure 7 As shown, the feeding mechanism also includes a second feeding component. The first feeding component 12 is located between the pressure roller 14 and the second feeding component. The second feeding component includes a feeding box 18 and a vibrating part 19. The feeding box 18 is connected to the support plate 112 of the mounting base 11. The vibrating part 19 can be considered as a vibrating motor and is connected to the side wall of the feeding box 18. The feeding box 18 includes a storage space with an opening 181 at the bottom. The width of the storage space gradually decreases towards the opening 181, meaning the storage space is generally truncated pyramidal in shape. The storage space is used to hold cement. The vibration of the vibrating part 19 allows the cement in the storage space to flow through the opening 181 to the ground, thus completing the cement spreading. By controlling the amplitude of the vibrating part 19, the speed at which the cement flows out of the feeding box 18 is controlled, preventing the cement thickness from becoming too thick.

[0044] The second feeding component also includes a pressure plate 17, which includes a horizontally arranged pressure section and an inclined guide section. The pressure section is located at the bottom of the pressure plate 17, and the plane of the guide section forms an obtuse angle with the plane of the pressure section. The height of the pressure side of the pressure plate 17 is higher than the height of the pressure position of the pressure roller 14. Specifically, the pressure side of the pressure plate 17 is the bottom side of the pressure section, and the height of the pressure side of the pressure plate 17 is the distance between the pressure side and the unpaved cement floor, that is, there is a certain distance between the pressure side of the pressure plate 17 and the cement leveling reference surface. In this embodiment, the height difference between the pressure side of the pressure plate 17 and the height of the pressure position of the pressure roller 14 is 1 mm to 6 mm. By setting the pressure plate 17, the cement can be leveled, thereby making the horizontal accuracy of the pressure roller 14 in leveling the cement higher.

[0045] In another embodiment, the feeding mechanism does not include the first feeding component 12, that is, the feeding mechanism only includes the second feeding component, so that the cement is leveled twice by the pressure plate 17 and the pressure roller 14 to complete the overall leveling of the cement.

[0046] In another embodiment, the first feeding component 12 does not include the feeding plate 13, so that the cement at the thicker position is moved to the outside of the moving path of the leveling component 1 by the cooperation of the rotating shaft 15 and the feeding plate 16, and then the cement is leveled twice by the pressing plate 17 and the pressing roller 14 to complete the overall leveling of the cement.

[0047] Reference Figure 2 As shown, the movable component includes a drive mechanism 2 and a first movable frame 4. The drive mechanism 2 includes a second drive member 22 and a movable plate 21. The movable plate 21 is slidably connected to the first movable frame 4. The second drive member 22 can be regarded as a rotation drive member. The second drive member 22 is connected to the movable plate 21. The output end of the second drive member 22 is connected to the first movable frame 4 through a transmission member. The transmission member can be regarded as a chain, so the movable plate 21 can be moved by the second drive member 22.

[0048] Reference Figure 8As shown, the ground leveling device also includes a lifting assembly 3, which includes a third drive component 31. The third drive component 31 is a linear drive component, specifically, it can be considered as a lifting electric cylinder. Two connecting frames 23 are connected to the top side of the movable plate 21. The output ends of the two third drive components 31 are respectively connected to the two connecting frames 23, and the drive rod of the third drive component 31 passes through the movable plate 21. The third drive component 31 is connected to the mounting base 11, enabling the mounting base 11 to be raised and lowered, thereby driving the pressure roller 14 and the feeding mechanism to be raised and lowered. This allows the leveling assembly 1 to level cement leveling reference surfaces of different heights, and the second drive component 22 can drive the leveling assembly 1 to move. A receiving box 24 is connected to the top side of the connecting frame 23, and the receiving box 24 is connected to the two connecting frames 23. The receiving box 24 can be used to hold electrical components. In another embodiment, the third drive component 31 is connected to the connecting frame 23, and the output end of the third drive component 31 is connected to the mounting base 11, so that the third drive component 31 can also drive the mounting base 11 to be raised and lowered.

[0049] The lifting assembly 3 also includes guide rods 34 and guide blocks 33. A connecting plate 32 is connected to each end of the movable plate 21, and the two connecting plates 32 are arranged opposite each other and parallel to each other. The guide blocks 33 are connected to the connecting plates 32, and the guide rods 34 are slidably connected to the guide blocks 33. One end of the guide rod 34 is connected to the mounting base 11, and the other end of the guide rod 34 is connected to a stop block 35. In this embodiment, one connecting plate 32 is connected to four guide blocks 33. Each guide rod 34 is slidably connected to two guide blocks 33, and the stop blocks 35 are connected to the ends of two guide rods 34. The stop blocks 35 limit the extreme movement of the mounting base 11, and the cooperation between the guide rods 34 and the guide blocks 33 guides the movement of the mounting base 11.

[0050] Reference Figure 9 , Figure 10 and Figure 11As shown, the first movable frame 4 includes a first connecting rod 41, a second connecting rod 42, and a third connecting rod 43. The centerline of the first connecting rod 41 is parallel to the centerline of the second connecting rod 42, and the third connecting rod 43 connects the first connecting rod 41 and the second connecting rod 42. Specifically, the central axis of the pressure roller 14 is perpendicular to the centerline of the first connecting rod 41. The ground leveling device also includes a support assembly 6, which includes a first connecting block 61, a second connecting block 62, a third connecting block 64, and multiple first support rods 63. The two ends of the third connecting rod 43 are located at the ends of the first connecting rod 41 and the second connecting rod 42, respectively. The length of the second connecting rod 42 is less than the length of the first connecting rod 41, so the third connecting rod 43 is inclined. The first connecting block 61 is connected to the first connecting rod 41, the second connecting block 62 is connected to the second connecting rod 42, and the third connecting block 64 is connected to the third connecting rod 43. The third connecting block 64 is sleeved on the end of the second connecting rod 42, that is, the third connecting block 64 is bent. The third connecting block 64 can also be connected to the second connecting rod 42, thereby making the connection between the third connecting rod 43 and the second connecting rod 42 more stable. Multiple first connecting blocks 61 are connected to the first connecting rod 41, with the first connecting blocks 61 corresponding to the positions of the second connecting block 62 and the third connecting block 64. A first support rod 63 connects between the first connecting blocks 61 and the second connecting block 62, and also connects between the first connecting blocks 61 and the third connecting block 64. The first support rod 63 is perpendicular to the first connecting rod 41, and its arrangement makes the connection between the first connecting rod 41, the second connecting rod 42, and the third connecting rod 43 more stable. The ends of the first connecting rod 41 and the third connecting rod 43 are connected by a fourth connecting block 49, thereby forming a support frame with the first connecting rod 41, the second connecting rod 42, and the two third connecting rods 43. The first movable frame 4 includes two support frames. The first connecting plate 32 is located between the first connecting rods 41. Preferably, the end of the first support rod 63 is connected to the connecting block via a second adjusting member. The overall length of the first support rod 63 and the second adjusting member is adjustable, thereby ensuring that the first connecting rods 41 of the two support frames remain parallel and preventing the movable plate 21 from being unable to slide along the first connecting rod 41 due to bending or other reasons. Specifically, the second adjusting member is threadedly connected to the first support rod 63 and can be fixed with a nut. By rotating the second adjusting member, the connection position between the second adjusting member and the first support rod 63 can be adjusted, thereby adjusting the overall length of the first support rod 63 and the second adjusting member. In another embodiment, the sidewalls of the second adjusting member and the first support rod 63 are provided with multiple threaded holes. The second adjusting member and the first support rod 63 are connected by bolts. By changing the connection position between the second adjusting member and the first support rod 63, the overall length of the first support rod 63 and the second adjusting member can be adjusted.

[0051] The first movable frame 4 also includes a fourth link 44, which is connected to the first link 41. Specifically, two fourth links 44 are respectively connected between the ends of the two first links 41, and the fourth link 44 is connected to the fourth connecting block 49. The first link 41 is provided with a slide rail, and the movable plate 21 is slidably connected to the first link 41. The fourth link 44 is connected to a baffle 45, and the opposite sides of the two baffles 45 are connected to a buffer 48. The buffer 48 can be regarded as a buffer, and the movable plate 21 can abut against the buffer 48 during movement, thereby limiting the extreme movement position of the movable plate 21 through the baffles 45 and the buffer 48. The top of the baffle 45 is rotatably connected to a sprocket, and a transmission component is sleeved on the sprocket, so that the movable plate 21 can be driven to move through the second driving component 22. In another embodiment, the second driving member 22 is regarded as a linear motor. Both ends of the second driving member 22 are connected to the baffle 45, and the driving end of the second driving member 22 is connected to the movable plate 21, so that the second driving member 22 can drive the movable plate 21 to move.

[0052] The first movable frame 4 also includes a fifth connecting rod 47, with two fifth connecting rods 47 respectively connected between the third connecting blocks 64, thereby making the overall structure of the first movable frame 4 more stable. The connecting blocks, connecting rods and the first support rod 63 of the first movable frame 4 are all connected by hand-tightening screws, which facilitates the assembly and disassembly of the first movable frame 4.

[0053] Reference Figure 1 , Figure 12 and Figure 13 As shown, the movable component also includes a fourth driving member (not shown) and a fixed frame 5. The first movable frame 4 is also connected to rolling members 46. In this embodiment, the four rolling members 46 are rotatably connected to the bottom of the four fourth connecting blocks 49 respectively. The rolling members 46 can be regarded as rollers. The rolling members 46 are connected to the output end of the fourth driving member, which is a rotary driving member. Specifically, the fourth driving member can be regarded as a rotary motor. The fourth driving member is connected to the first movable frame 4, and the rolling members 46 abut against the fixed frame 5. The fourth driving member enables the first movable frame 4 to move on the fixed frame 5, and the movement path of the first movable frame 4 is perpendicular to the movement path of the movable plate 21, thereby enabling the leveling component 1 to move to different positions. The leveling path of the pressure roller 14 is perpendicular to the movement path of the first movable frame 4.

[0054] The fixing frame 5 includes at least two guide rails 51. In this embodiment, the fixing frame 5 includes two guide rails 51. Each guide rail 51 includes multiple support feet 55 and multiple second support rods 52. The second support rods 52 are cylindrical. Rolling elements 46 abut against the guide rails 51 of the fixing frame 5. In this embodiment, each guide rail 51 abuts against two rolling elements 46. The sidewall of the rolling element 46 is provided with a groove, and the sidewall of the groove abuts against the sidewall of the second support rod 52, so that the rolling element 46 can roll stably on the second support rod 52. The center lines of the multiple second support rods 52 are collinear. A connector 53 is engaged between two adjacent second support rods 52. The connector 53 can be regarded as a connecting pin. The end of the second support rod 52 is provided with a connecting groove, and the connector 53 engages with the connecting groove, so that two adjacent second support rods 52 are connected. The second support rod 52 abuts against the support feet 55. The top of the support foot 55 is provided with a slot 54, which can engage with the second support rod 52. The bottom of the support foot 55 can be placed on the ground, or it can be connected to a wall. Preferably, the support foot 55 is an adjustable lifting support foot 55, so that the height of the support foot 55 can be adjusted. When the mounting surface for installing the support foot 55 is uneven, the height of the support foot 55 can be adjusted to make the center lines of the multiple second support rods 52 of the guide rail 51 collinear, preventing the guide rail 51 from bending and improving the leveling accuracy of the leveling component 1 in leveling the cement. In another embodiment, the two guide rails 51 in the fixing frame 5 are an integral structure, thus eliminating the need for assembly.

[0055] All components of the fixed frame 5 and the first movable frame 4 can be detached and connected, which facilitates the transportation and assembly of the fixed frame 5 and the first movable frame 4, and also facilitates the adjustment of the size of the fixed frame 5 and the first movable frame 4, so that the fixed frame 5 and the first movable frame 4 can be used in different sites.

[0056] Reference Figure 14 and Figure 15 As shown, in another embodiment, the movable component no longer includes the first movable frame 4, but includes a second movable frame 7. The second movable frame 7 also includes a baffle 45 and a rolling element 46, and the structure and operation of the baffle 45 and the rolling element 46 of the second movable frame 7 are the same as those of the first movable frame 4, which will not be described again. The second movable frame 7 includes two sixth connecting rods 71, and a slide rail is provided on the sixth connecting rod 71. The movable plate 21 is slidably connected to the slide rail. The central axis of the pressure roller 14 is parallel to the center line of the sixth connecting rod 71, so that the distance between the sixth connecting rods 71 ​​is smaller than the distance between the first connecting rods 41, and the leveling path of the pressure roller 14 is parallel to the moving path of the second movable frame 7. Thus, different embodiments can be selected according to different cement floor leveling methods.

[0057] In use, the ground leveling device of this utility model can use premixed mortar construction materials. The first movable frame 4 moves a certain distance on the fixed frame 5 so that the leveling component 1 corresponds to the unleveled cement. Then, the first driving component 141 drives the pressure roller 14 and the first feeding component 12 to rotate. The second driving component 22 drives the movable plate 21 to move, thereby driving the leveling component 1 to move. The leveling component 1 moves from a position close to one guide rail 51 to another guide rail 51. The first feeding component 12 is located in front of the pressure roller 14 along the moving path of the leveling component 1. The cement in the thicker part of the ground can enter the feeding space. Then the cement enters the receiving space of the first feeding component 12. The rotation of the first feeding component 12 moves the cement in the receiving space away from the moving path of the leveling component 1. Finally, the pressure roller 14 squeezes and levels the cement during the rotation process. When the ground leveling device also includes a second feeding component, the ground does not need to be laid with cement first. The vibration of the vibrating part 19 causes the cement in the storage space to flow to the ground through the opening 181 of the storage space. Finally, the cement can also be squeezed and leveled by the pressure roller 14 during rotation. In the prior art, cement can usually only be used for wet-mixed mortar. Wet-mixed mortar has a large shrinkage rate, is prone to cracking, and requires curing after hardening. It also has low compressive strength. However, the ground leveling device of this utility model can use pre-mixed mortar. Pre-mixed mortar is in a semi-cured state, has a small shrinkage rate, is not prone to cracking, has high compressive strength, and requires no curing after hardening.

[0058] This utility model discloses a ground leveling device. Through the rotation of the first feeding component 12, thicker sections of cement on the ground are moved away from the moving path of the leveling component 1. The feeding plate 13 performs the first leveling of the cement, ensuring it is close to the cement leveling reference surface before the pressure roller 14 levels it. Finally, the pressure roller 14 performs a second leveling with higher precision, resulting in a higher leveling accuracy for the cement. The pressure plate 17 also levels the cement, further enhancing the leveling accuracy of the pressure roller 14. The movable frame and fixed frame 5 allow the leveling component 1 to move on the cement, eliminating the need for manual leveling and thus achieving even higher leveling accuracy.

[0059] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
