During the leveling process, the soil may become pitted due to gravel and other debris, and the soil may be loose and not compacted. In addition, as land development progresses, relying on a single type of equipment can easily lead to low work efficiency, and equipment needs to be replaced when performing other operations. Summary of the Invention

[0004] The purpose of this invention is to provide a ground leveling device for land development and remediation, which solves the following technical problems: Conventional leveling equipment is used to level building foundations. Using equipment such as excavators is time-consuming and labor-intensive. During the leveling process, the soil may become pitted due to gravel and other debris, and the soil may be loose and not compacted. At the same time, as the land development progresses, the single equipment is prone to low work efficiency, and the equipment needs to be changed when other operations are performed.

[0005] The objective of this invention can be achieved through the following technical solutions: A ground leveling device for land development and remediation includes: a machine frame, a fixed horizontal plate that is lifted and lowered by a hydraulic cylinder is installed on the left side inside the machine frame, a main control box is installed at the lower middle of the fixed horizontal plate, a drive gear disk is provided on both the front and rear sides inside the main control box, and a movable support vertical plate located inside the side plate is provided on the outer side of the drive gear disk for reciprocating lifting and lowering of the compacted plate. The right side of the tamping plate is equipped with a leveling roller connected to the movable support crossbar, and the right side of the leveling roller is equipped with a cleaning brush for cleaning the foundation.

[0006] As a further aspect of the present invention: a driven gear disk is provided on the inner side of the driving gear disk for meshing connection, a first connecting rod is fixedly connected to the outer end of the driving gear disk, and a second connecting rod is provided on the outer end of the first connecting rod for connection with the movable support vertical plate.

[0007] As a further aspect of the present invention: the first connecting rod and the second connecting rod form a rotating structure, and the second connecting rod rotates on the movable support vertical plate to make it perform a locking lifting movement in the side plate using the clearance groove.

[0008] As a further aspect of the present invention: the front and rear sides of the upper end of the rammed plate are fixedly installed with reinforcing ribs that are threadedly connected to the movable support vertical plate by bolts.

[0009] As a further aspect of the present invention: both the first connecting rod and the second connecting rod rotate in a circular motion around the active gear disk as the center point, and the travel distance of the movable support vertical plate is less than twice the diameter of the first connecting rod.

[0010] As a further aspect of the present invention: the movable support crossbar and the reciprocating lead screw are connected by a thread, and the first conical toothed disc and the second conical toothed disc fixedly installed at the inner end of the reciprocating lead screw are meshed together.

[0011] As a further aspect of the present invention: a first linkage gear disk that meshes with the first internal toothed belt is fixedly installed on the upper end of the second conical toothed disk, and side plates for centering the first internal toothed belt are provided at both the upper and lower ends of the first linkage gear disk.

[0012] As a further aspect of the present invention: the movable support crossbar forms a locking lateral movement within the frame of the machine, and the lower inner side of the movable support crossbar is rotatably connected to a linkage shaft block that engages with the leveling roller.

[0013] As a further aspect of the present invention: a water injection pipe is provided on the upper front end of the leveling roller and is threadedly connected to the threaded sealing block, and the inner side of the leveling roller is hollow. A scraper is provided on the right side of the leveling roller, which moves up and down within the machine frame via a damping spring.

When the rotating drive gear disk is turned on, it can drive the movable support vertical plate to move up and down in the side plate under the linkage. The rapid rotation of the drive gear disk can improve the vibration effect of the movable support vertical plate, so as to achieve continuous and uninterrupted vibration and compaction of the building foundation surface. Additionally, the movable support vertical plate is connected to the reinforcing ribs at the upper end of the rammed plate by bolts in a threaded manner, which facilitates the independent disassembly, replacement and maintenance of the entire rammed plate in the future. 2. After the foundation of the building is compacted by the tamping plate, the leveling roller is used to level the foundation. This reduces the soil's resilience and allows the soil to be stressed again in a short time to achieve the leveling effect. The movable support crossbar forms a snap-fit ​​sliding structure within the frame of the machine, which allows the leveling roller to be disassembled and replaced as a whole according to the actual width of the foundation. Additionally, a scraper is attached to the right end of the leveling roller to remove impurities brought up during leveling. The scraped-off impurities are then cleaned up using a cleaning brush.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0020] Please see Figure 1-9 As shown, the present invention is a ground leveling device for land development and remediation.

[0021] Example 1 Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 In this invention, a technical solution is provided: a machine frame 1, a fixed horizontal plate 3 that is lifted and lowered by a hydraulic cylinder 301 is installed on the left side inside the machine frame 1, a main control box 302 is installed at the lower middle of the fixed horizontal plate 3, a drive gear disk 3022 is provided on both the front and rear sides inside the main control box 302, and a movable support vertical plate 3032 located inside the side plate 303 is provided on the outer side of the drive gear disk 3022 for reciprocating lifting and lowering of the compaction plate 304; Furthermore, a driven gear disk 3023 is meshed with the inner side of the driving gear disk 3022, and a first connecting rod 3024 is fixedly connected to the outer end of the driving gear disk 3022. A second connecting rod 3025 is provided at the outer end of the first connecting rod 3024 and connected to the movable support vertical plate 3032.

[0022] Furthermore, the first connecting rod 3024 and the second connecting rod 3025 form a rotating structure. The second connecting rod 3025 rotates on the movable support vertical plate 3032 to make it engage and lift within the side plate 303 using the clearance groove 3031.

[0023] Furthermore, the front and rear sides of the upper end of the rammed plate 304 are fixedly installed with reinforcing ribs 3041 that are threadedly connected to the movable support vertical plate 3032 by bolts 305.

[0024] Furthermore, both the first connecting rod 3024 and the second connecting rod 3025 rotate in a circular motion around the driving gear disk 3022 as the center point, and the travel distance of the movable support vertical plate 3032 is less than twice the diameter of the first connecting rod 3024.

[0025] Specifically, the entire frame 1 is first towed to the vehicle. The vehicle's driving force moves the entire frame 1, and the casters 2 allow for flexible rotation. As the frame 1 slowly moves on the building foundation, the hydraulic cylinder 301 is activated to drive the fixed cross plate 3 downwards, positioning the compacted plate 304 on the upper side of the foundation. The distance between the lower surface of the compacted plate 304 and the upper surface of the foundation is no more than one meter. At this time, the first servo motor 3021 installed inside the main control box 302 is activated. Since the inner side of the drive gear disk 3022 is equipped with a meshing driven gear disk 3023, when the first servo motor 3021 is activated to rotate the drive gear disk 3022, it can drive the meshing driven gear disk 3023. The driven gear disk 3023 rotates synchronously, thereby driving another active gear disk 3022 to rotate synchronously. This is in conjunction with the drive of the first servo motor 3021, thereby enhancing the overall rotational force of the active gear disk 3022. Since the first connecting rod 3024 is fixedly installed on the outer end of the active gear disk 3022, and the first connecting rod 3024 rotates in a circular motion around the active gear disk 3022, it can drive the second connecting rod 3025, which is movably connected to the outside of the first connecting rod 3024, to rotate synchronously. This allows the movable support vertical plate 3032, which is rotatably connected to the outside of the second connecting rod 3025, to move stably up and down within the side plate 303 through the clearance groove 3031.

[0026] Additionally, the movable support vertical plate 3032 is connected to the reinforcing ribs 3041 fixedly installed on the front and rear sides of the upper end of the compaction plate 304 by bolts 305 and by threads. When the movable support vertical plate 3032 moves up and down in the side plate 303, it can drive the compaction plate 304 to move up and down as a whole, so as to use the compaction plate 304 to vibrate and compact the building foundation, thereby achieving the effect of compacting the building foundation and avoiding the phenomenon of soil separation caused by weeds and other materials. Before this operation, the building foundation can be manually sprinkled with water, which can not only reduce the dust generated during vibration and achieve the effect of dust suppression, but also improve the surrounding environment.

[0027] The movable support vertical plate 3032 has a travel distance within the side plate 303 that is less than twice the diameter of the first connecting rod 3024. Since the first connecting rod 3024 rotates in a circular motion around the active gear disk 3022, it can drive the second connecting rod 3025 to rotate up and down in a fan shape during the continuous rotation of the first connecting rod 3024, thereby continuously providing driving force to the movable support vertical plate 3032. This allows the compaction plate 304 to effectively vibrate the compaction of the building foundation. The detachable structure facilitates the independent disassembly and replacement of the compaction plate 304 in the later stages, improving work efficiency.

[0028] The upper right side of the frame 1 has a storage cavity 101, and the right end of the storage cavity 101 is rotatably connected to a movable door panel 102. The storage cavity 101 can be used to store some commonly used tools for easy replacement, such as a tamping plate 304 or a cleaning brush 505.

[0029] Example 2 Please see Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 9 In this invention, a technical solution is provided: a leveling roller 4013 connected to a movable support crossbar 4 is provided on the right side of the tamping plate 304, and a cleaning brush 505 for cleaning the foundation is provided on the right side of the leveling roller 4013. Furthermore, the movable support crossbar 4 and the reciprocating screw 401 are connected by threads, and the first conical toothed disc 402 and the second conical toothed disc 403, which are fixedly installed at the inner end of the reciprocating screw 401, are meshed together.

[0030] Furthermore, a first linkage gear disk 404 that meshes with the first internal gear belt 405 is fixedly installed on the upper end of the second conical gear disk 403. Both the upper and lower ends of the first linkage gear disk 404 are provided with side plates that center the first internal gear belt 405.

[0031] Furthermore, the movable support crossbar 4 forms a snap-fit ​​lateral movement within the machine frame 1, and the lower inner side of the movable support crossbar 4 is rotatably connected to a linkage shaft block 4012 that engages with the leveling roller 4013.

[0032] Furthermore, a water injection pipe 40131 is provided on the upper front end of the leveling roller 4013, which is threadedly connected to the threaded sealing block 40132, and the inner side of the leveling roller 4013 is hollow. A scraper 407 is provided on the right side of the leveling roller 4013. The scraper 407 moves up and down within the frame 1 via a damping spring 4071. The scraper 407 forms a snap-fit ​​sliding connection on the inside of the mounting box 5.

[0033] Specifically, in conjunction with Embodiment 1, due to the continuous compaction of the building foundation by the tamping plate 304, the uncertainty of its force on the soil will cause the soil to form an area with the tamping plate 304 as the main shape. At this time, the third servo motor 4011 is turned to rotate the linkage shaft block 4012, and the leveling roller 4013 can be used to level the compacted building foundation. Since the upper front end of the leveling roller 4013 is equipped with a water injection pipe 40131, and the inner thread of the water injection pipe 40131 is sealed with a threaded sealing block 40132, sufficient water can be added to the leveling roller 4013 before the leveling operation to increase the overall weight of the leveling roller 4013. This method not only saves resources but also improves the usage effect. After use, the water can be poured out from the leveling roller 4013 to spray water on the building foundation to reduce dust.

[0034] The leveling roller 4013 and the linkage block 4012 are connected by a snap-fit ​​mechanism. When the fourth servo motor 406 is turned on to rotate the first linkage gear disk 404, it can drive the first internal gear belt 405, which is meshed with the outer side of the first linkage gear disk 404, to rotate synchronously. This drives the second conical gear disk 403, which is fixedly installed at the lower end of the first linkage gear disk 404, to rotate synchronously. Since the second conical gear disk 403 and the first conical gear disk 402 are connected by a meshing mechanism, the first conical gear disk 402 will rotate synchronously and in the same direction under the action of the first internal gear belt 405. The first conical gear disk 402 drives the reciprocating screw 401 to rotate at a uniform speed, so that the movable support crossbar 4 can slide back and forth laterally within the frame 1. This method not only allows for the disassembly and maintenance of the leveling roller 4013, but also facilitates the replacement of a wider leveling roller 4013 according to the leveling range of the building foundation, so as to achieve the effect of one-time leveling and forming.

[0035] The 4013 leveling roller is made of high-chromium alloy steel with a chromium content of 10%-22%. The resulting M7C3 type carbide has extremely high hardness and wear resistance superior to ordinary cast iron. Chromium enhances its corrosion resistance, making it suitable for soil environments in humid or rainy areas, and providing strong strength and durability.

[0036] In the process of leveling the building foundation by the leveling roller 4013, the vehicle towed at the front end of the machine frame 1 provides active traction, and the water filling inside the leveling roller 4013 increases its own weight. In addition, the third servo motor 4011 at the rear end of the leveling roller 4013 provides active rotational force, which can greatly increase the force of the leveling roller 4013 on the surface of the building foundation and enhance the leveling effect.

[0037] The leveling roller 4013 has a scraper 407 attached to its right end. When the leveling roller 4013 is leveling the foundation of a building, a small amount of soil or weeds will be carried up with it. The scraper 407 can then be used to scrape off the debris adhering to the leveling roller 4013. Under the elastic action of the damping spring 4071, the scraper 407 can be kept close to the outer surface of the leveling roller 4013 to prevent it from scratching the roller. The scraped debris will fall behind the leveling roller 4013. As shown in the figure, the scraper 407 forms a sliding structure with the groove on the left end of the mounting box 5, which can ensure the overall stability of the scraper 407 and prevent shaking.

[0038] Example 3 Please see Figure 1 , Figure 2 , Figure 3 and Figure 8 In this invention, a technical solution is provided: a movable mounting plate 504 is provided at the upper end of the cleaning brush 505 and is fixedly connected to the second linkage gear disk 502, and a second internal tooth belt 503 is meshed with the outer side of the second linkage gear disk 502.

[0039] Specifically, in conjunction with Embodiment 1 and Embodiment 2, after the leveling roller 4013 completes the leveling operation on the building foundation, the fifth servo motor 501 installed inside the mounting box 5 is opened. When the second linkage gear disk 502 is rotated, it drives the second internal gear belt 503 meshing with the outer side of the second linkage gear disk 502 to rotate synchronously. Thus, the second linkage gear disk 502 drives the movable mounting disk 504 to rotate as a whole, and the cleaning brush 505 set at the lower end of the movable mounting disk 504 sweeps away the impurities scraped off by the scraper 407, keeping the surface of the building foundation clean.

[0040] Among them, the cleaning brush 505 is made of nylon synthetic fiber, which is wear-resistant and chemically resistant. Different hardnesses can be selected to reduce the risk of wear on the building foundation surface. It is gentler than metal wire brushes, and can not only resist impact but also protect the surface of the building foundation.

[0041] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
