A flat floor 10 is fixedly connected to the lower surface of the first connecting frame 4. A driving component is provided inside the connecting plate 8, and the driving component is used to provide vibration.

[0025] Specifically, the connecting rod 3 plays a role in connecting the first U-shaped block 2 and the second connecting frame 24. The second connecting frame 24 plays a role in supporting the connecting plate 8 through the connecting column 9, and thus plays a role in connecting and fixing the double-headed motor 11. The vibration generated by the vibration block 12 drives the spring 6 to swing up and down through the third U-shaped block 7. The first connecting frame 4 is connected to the second U-shaped block 5, and thus drives the flat floor 10 to play a role in tamping and leveling the ground again.

[0026] Reference Figure 1 As shown in Figure 1 , the driving assembly includes a double-headed motor 11. The outer wall of the double-headed motor 11 is fixedly connected to the inside of the connecting plate 8, and the output end of the double-headed motor 11 is fixedly connected to a vibration block 12.

[0027] Specifically, the double-headed motor 11 drives the vibration block 12 to rotate and generates vibration at the same time.

[0028] Reference Figure 1 、 Figure 3 and Figure 4 As shown in Figure 1 , Figure 3 and Figure 4 , a first earth-moving blade 13 is fixedly connected to the outer wall of the grader body 1. A protective housing 17 is fixedly connected to the outer wall of the first earth-moving blade 13. A servo motor 18 is fixedly connected to the inside of the protective housing 17. The output end of the servo motor 18 is fixedly connected to a gear 19. The outer wall of the gear 19 is meshed with a rack 20. A limiting frame 21 is fixedly connected to the outer wall of the first earth-moving blade 13. The outer wall of the rack 20 is slidably connected to the inner wall of the limiting frame 21. A connecting block 22 is fixedly connected to the outer wall of the rack 20. A first sliding groove 14 is formed in the first earth-moving blade 13. The outer wall of the connecting block 22 is slidably connected to the inner wall of the first sliding groove 14. A second earth-moving blade 23 is fixedly connected to the outer wall of the connecting block 22. A slide rail 25 is fixedly connected to the outer wall of the second earth-moving blade 23. A second sliding groove 15 is formed in the first earth-moving blade 13. The outer wall of the slide rail 25 is slidably connected to the inner wall of the second sliding groove 15. An L-shaped block 16 is fixedly connected to the upper surface of the first earth-moving blade 13. The outer wall of the second earth-moving blade 23 is slidably connected to the inner wall of the L-shaped block 16, and the outer wall of the second earth-moving blade 23 is slidably connected to the outer wall of the first earth-moving blade 13.

[0029] Specifically, the first earth-moving blade 13 drives the second earth-moving blade 23 to level the ground for the first time. The servo motor 18 drives the rack 20 to slide inside the limiting frame 21 through the gear 19. The limiting frame 21 limits the movement of the rack 20. Further, the rack 20 drives the connecting block 22 to slide in the first sliding groove 14 and drives the second earth-moving blade 23 to slide in the L-shaped block 16 at the same time. The L-shaped block 16 limits the second earth-moving blade 23. The second earth-moving blade 23 drives the slide rail 25 to slide in the second sliding groove 15.

[0030] Working principle: When the device needs to be used, while the grader body 1 is moving forward, the second dozer blade 23 is driven to move forward together with the first dozer blade 13, so as to level the ground for the first time. The servo motor 18 drives the rack 20 to slide inside the limit frame 21 through the gear 19. Then, while the rack 20 drives the connecting block 22 to slide in the first sliding groove 14, it drives the second dozer blade 23 to slide in the L-shaped block 16. The second dozer blade 23 drives the slide rail 25 to slide in the second sliding groove 15, so that the width of the soil leveling block can be adjusted as required. While the grader body 1 is moving forward, the first U-shaped block 2 drives the second connecting frame 24 to move forward through the connecting rod 3. At the same time, the double-headed motor 11 drives the vibration block 12 to rotate and generate vibration. The second connecting frame 24 supports the connecting plate 8 through the connecting column 9, thus playing a role in connecting and fixing the double-headed motor 11. The vibration generated by the vibration block 12 drives the spring 6 to swing up and down through the third U-shaped block 7. Then, the second U-shaped block 5 drives the flat floor 10 through the first connecting frame 4 to tamp and level the ground again, making the effect of leveling the ground better. The protective shell 17 plays a role in supporting and fixing the servo motor 18. This device can not only achieve the effect of tamping and leveling the leveled ground again, but also achieve the effect of adjusting the width of the soil leveling block as required.
