[0014] The device will now be described more fully hereinafter with reference to the accompanying drawings, in which currently preferred embodiments of the device are shown. The device may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and fully convey the scope of the device to those skilled in the art.

[0015] As Figure 1 and Figure 2The earthwork paving device shown is composed of a tractor 1, a horizontal telescopic arm 2 installed on one side of the tractor 1, and a loosening mechanism 5, a leveling mechanism 6 and a scraper 7 installed at the front end of the horizontal telescopic arm 2. The device is moved by the tractor 1, and the coverage area is expanded by the telescopic feature of the horizontal telescopic arm 2. The earthwork paving device is leveled and compacted on the foundation by the combined action of the loosening mechanism 5, the leveling mechanism 6 and the scraper 7.

[0016] Specifically, the horizontal telescopic arm 2 is installed at the bottom of the tractor 1 and extends towards the front end of the tractor 1. A cross beam 3 is fixed at the front end of the horizontal telescopic arm 2. Two vertical lifts 4 are arranged at the two ends of the cross beam 3. In this embodiment, the vertical lifts 4 are air cylinders. A loosening mechanism 5 is arranged at the bottom of the telescopic rod of the vertical lift 4. A leveling mechanism 6 is arranged at the front side of the loosening mechanism 5, and a scraper 7 is arranged at the rear side of the loosening mechanism 5. The loosening mechanism 5 includes a frame 51, loosening rollers 52 and a driving motor 53. Specifically, the frame 51 is fixed at the bottom of the telescopic rod of the vertical lift 4. The loosening rollers 52 are rotatably arranged on the frame 51. The driving motor 53 is installed on the frame 51 and is in transmission connection with the rotating shaft of the loosening rollers 52, for driving the loosening rollers 52 to rotate. The loosening mechanism 5 is integrated at the bottom of the telescopic rod of the vertical lift 4, so that the device can accurately vibrate and compact the earthwork. The loosening rollers 52 rotate under the driving of the driving motor 53 to vibrate and compact the earthwork. This vibration mode can effectively improve the compactness of the earthwork and ensure its stability, and is more efficient and uniform than the traditional manual vibrator.

[0017] Specifically, in this embodiment, the leveling mechanism 6 includes a plurality of horizontal ear plates 61 arranged at the front side of the frame 51. A vertical shaft 62 is slidably arranged on each horizontal ear plate 61. The lower ends of the vertical shafts 62 are connected to a leveling plate 63. A plurality of vibration motors 64 are arranged on the upper side of the leveling plate 63. An adjusting nut 65 is arranged at the upper end of the vertical shaft 62. The part of the vertical shaft 62 between the ear plate and the adjusting nut 65 is sleeved with an upper spring 66. The part of the vertical shaft 62 between the ear plate and the leveling plate 63 is sleeved with a lower spring 67. The compression amount of the spring can be adjusted by the adjusting nut 65. By adjusting the adjusting nut 65 and the spring, the device can adapt to different ground conditions and ensure the consistency of the leveling effect. The vibration motors 64 arranged on the upper side of the leveling plate 63 can generate vibration during the leveling process, helping the earthwork to be more closely attached, improving the leveling efficiency and quality. The upper and lower springs 67 arranged on the vertical shaft 62 provide a buffering effect, reducing the impact of the leveling plate 63 when encountering uneven ground, protecting the device and improving the stability of the leveling.
