However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments of the specification disclosed below. The present invention is further described in detail below with reference to the accompanying drawings.

[0052] Example 1: A ground leveling device, such as Figures 1-14As shown, it includes a frame 1, a transverse moving bracket 6 and a longitudinal moving bracket 7. A symmetrically arranged hydraulic cylinder 3 is provided on the frame 1. The hydraulic cylinder 3 is connected to the vibrating device 4 through the lifting and adjusting frame 2. The lifting and adjusting frame 2 is movably connected to the leveling component 5 on the side away from the vibrating device 4. The frame 1 is connected to the symmetrically arranged transverse moving bracket 6 through the transverse driving group 8. Both ends of the transverse moving bracket 6 are detachably installed with a fixed seat 9. The fixed seat 9 is connected to the symmetrically arranged longitudinal moving bracket 7 through the longitudinal driving group 10. The two hydraulic cylinders 3 make the lifting and adjusting frame 2 more stable and balanced, effectively avoiding To avoid equipment tilting due to uneven force on one side, the vibration device 4 softens the cast cement floor to make it easier for the leveling component 5 to smooth it out. Vibration can also effectively eliminate bubbles and gaps on the ground, improve the density and flatness of the ground, and cause the originally high or uneven cement surface to settle, making the cement floor more uniform and reducing the workload of the subsequent leveling component 5. The leveling component 5 then performs fine scraping to ensure leveling efficiency. All parts of the equipment adopt a detachable or adjustable connection method, which can be adjusted according to different casting surface areas.

Multiple gears can effectively provide support, one of which is connected to the drive end of the drive motor for driving. The two brackets are vertically staggered, and the transverse bracket 6 as a whole is driven by the longitudinal drive group 10 on the fixed seat 9 to move on the longitudinal bracket 7.

[0054] The vibration device 4 includes a vibration motor 41, a spring buffer rod 42 and an abutment plate 43. The vibration motor 41 is installed on the top surface of the abutment plate 43.

The rebound pull rod 622 is retracted to make the clamping fixing strip 623 fall and clamped in the slot on the positioning column 63. At this time, the two transverse rails 61 are assembled. Repeat the operation until it meets the requirements for pouring cement surface.

[0066] Secondly, to assemble the longitudinal movement bracket 7, you only need to take the second positioning card seat 72, clamp the second positioning card seat 72 between the two adjacent longitudinal movement rails 71, and then operate the limit block 76 to allow the limit block 76 to be clamped on the clamping groove of the second positioning card seat 72. Then, the two adjacent longitudinal movement rails 71 can be installed through the second positioning card seat 72. Repeat the operation until it meets the requirements for pouring the cement surface.

[0067] Step B: Lock both ends of the transverse moving bracket 6 with the fixing seat 9 and place it on the longitudinal moving bracket 7;

After the assembly is completed, the longitudinal bracket 7 is raised on the ground to be leveled by sleepers.

[0069] Step C: The frame 1 is mounted on the transverse support 6 via the transverse drive assembly 8;

[0070] The frame 1 is set between two parallel transverse brackets 6, and the first gear on the transverse drive group 8 is engaged with the first rack on the transverse bracket 6.

[0071] Step D: The hydraulic cylinder 3 adjusts the vibration device 4 to fit the casting surface, and adjusts the leveling component 5 to fit the casting surface as well;

[0072] Start the hydraulic cylinder 3 to drive the lifting adjustment frame 2 to move downward, so that the abutment plate 43 is in contact with the ground, and the angle of the trowel plate 57 is adjusted by rotating the positioning plate 52 and the adjusting cap 56, and the leveling adjustment frame 51 is adjusted to adjust the height of the trowel plate 57 so that the trowel plate 57 is in contact with the ground. After the adjustment is completed, take the locking bolt 12 and thread the locking bolt 12 into the threaded hole formed by the positioning plate 52 and the arc plate 53, locking the position of the arc plate 53 and the positioning plate 52, thereby locking the position of the trowel plate 57.

[0073] Step E: Start the vibration device 4 to vibrate the casting surface, and then smooth it through the leveling component 5;

[0074] Step F: The transverse drive group 8 and the longitudinal drive group 10 drive the device to move transversely and longitudinally to complete the leveling of the ground;

[0075] Start the vibration motor 41 to drive the abutment plate 43 to vibrate, vibrate the cement floor, and then smooth it with the trowel plate 57. The first motor in the transverse drive group 8 drives the first gear to rotate, and the first gear engages with the first rack in the transverse track 61 to enable the frame 1 to move in the transverse track 61. The second motor in the longitudinal drive group 10 drives the second gear to rotate, and the second gear engages with the second rack in the longitudinal track 71, which is driven by the fixed seat 9 to enable the transverse bracket 6 to move on the longitudinal bracket 7, and finally complete the leveling of the ground. The transverse bracket 6 and the longitudinal bracket 7 are vertically staggered.
