When the handlebar 12 is pulled to drive the front wheel 13 to deflect, the front wheel 13 can be conveniently pushed down; when the front wheel 13 is retracted, the pressing plate 40 can be conveniently flattened on the ground; when the front wheel 13 deflects back and forth, the pressing plate 40 can be lifted from the ground, and at the same time, the scraping rod 60 can be used to scrape off the adhering objects along the lower surface of the pressing plate 40, and the elastic element 50 can keep the scraping rod 60 always in close contact with the lower surface of the pressing plate 40, so that the cleaning effect is ensured.

[0031] Please refer to Figures 1-4 The rear end of the frame 11 is fixedly connected with a pushing handle 14, and the rear end of the frame 11 is provided with a rear wheel 15. The front wheel 13 and the rear wheel 15 form a four-wheel cart, and the rear wheel 15 is a universal wheel, which can be conveniently pushed by the pushing handle 14 and is convenient for transfer.

[0032] Please refer to Figures 1-4 A water tank 70 is arranged on the frame 11. Water can be added in the water tank 70 to serve as a counterweight, so that the pressing plate 40 is increased in impact force and the flattening effect is improved.

[0033] Please refer to Figures 1-4 The front end of the frame 11 is fixedly connected with a guide plate 16, the guide plate 16 is in abutment with the pressing plate 40, and the scraping rod 60 slides along the surface of the guide plate 16. When the pressing plate 40 is flattening, the front wheel 13 is retracted, and the scraping rod 60 is located on the surface of the guide plate 16. When the pressing plate 40 needs to be cleaned, the pressing plate 40 is retracted to the position of the guide plate 16, the guide plate 16 plays a limiting role, and the guide plate 16 is aligned with the edge of the pressing plate 40, so that the scraping rod 60 can be smoothly moved to the lower surface of the pressing plate 40.

[0034] Please refer to Figures 1-4 A spring pin 17 is arranged on the handlebar 12 and is pinned to the frame 11. When the front wheel 13 is retracted and lowered, the current posture is locked through the pinning of the spring pin 17 to the frame 11.

[0035] Please refer to Figures 1-4The lifting mechanism 20 includes a guide rod 21 and a mounting plate 22. The lower end of the guide rod 21 is fixedly connected to the mounting plate 22, and the guide rod 21 is slidably connected to the frame 11. The vibration motor 30 is mounted on the mounting plate 22. The lifting mechanism 20 also includes a motor 23 and a lead screw 24. The lead screw 24 is rotatably connected to the frame 11 and threadedly connected to the mounting plate 22. The motor 23 is mounted on the frame 11, and the output end of the motor 23 is poweredly connected to the lead screw 24. The dual-head motor 23 synchronously drives the two lead screws 24 to rotate through two sets of bevel gears, thereby driving the mounting plate 22 to rise and fall, adjusting the height of the pressure plate 40. The vibration motor 30 applies vibration to the pressure plate 40 to level the ground.

[0036] Please see Figures 1-4 The elastic element 50 includes a groove 51 and a slider 52. The groove 51 is fixedly connected to the throttle 12, and the slider 52 slides within the groove 51. A tension spring 53 is provided between the groove 51 and the slider 52. The two ends of the scraper 60 are fixedly connected to the corresponding sliders 52. The tension spring 53 maintains the action of pulling the slider 52, so that the scraper 60 remains in a retracted posture and can press against the surface of the guide plate and the pressure plate 40. In this embodiment, the scraper 60 is circular, and a cutting edge is axially provided around its surface. This way, no matter what angle the scraper 60 rotates to, the corresponding cutting edge can be used to clean the adhering substances on the surface of the pressure plate 40.

[0037] The working principle of this road leveling construction device is as follows: During transport, the front wheel 13 is lowered, and the front wheel 13 and the rear wheel 15 form a four-wheeled cart for easy pushing. When leveling work is carried out, the spring pin 17 is opened, the handle 12 is pulled, and the front wheel 13 is retracted forward and upward. Then, the spring pin 17 is locked. Then, the double-headed motor 23 drives the two lead screws 24 to rotate synchronously through two sets of bevel gears, thereby driving the mounting plate 22 to descend and adjusting the height of the pressure plate 40. The vibration motor 30 applies vibration to the pressure plate 40 to level the ground. When it is necessary to clean the surface of the pressure plate 40, the motor 23 first retracts the pressure plate 40 and presses it against the guide plate. The guide plate 16 is aligned with the edge of the pressure plate 40. Then, the handle is pulled. 12 causes the front wheel 13 to lift the pressure plate 40 off the ground, while the scraper 60 slides from the guide plate surface to the lower surface of the pressure plate 40. The tension spring 53 keeps the scraper 60 in close contact with the lower surface of the pressure plate 40 until it moves to the guide plate on the other side, then returns to its original position, and continues the leveling work. In summary, pulling the handle 12 causes the front wheel 13 to deflect. When the front wheel 13 is lowered, it is easy to push; when the front wheel 13 is raised, it is easy for the pressure plate 40 to be flat on the ground; when the front wheel 13 deflects back and forth, it can lift the pressure plate 40 off the ground, and at the same time, the scraper 60 scrapes off the attached substances along the lower surface of the pressure plate 40. The elastic element 50 can keep the scraper 60 in close contact with the lower surface of the pressure plate 40 at all times to ensure the cleaning effect.
