[0002] The construction of high-grade highway stone-filled roadbeds should be carried out in layers and compacted in layers. The loose paving thickness of each layer should not exceed 0.5m. When using a heavy-duty vibratory roller to compact the stone-filled roadbed, the loose paving thickness can be increased to 1.0m. The stone-filled roadbed should be spread flat before compaction.

[0003] For the leveling process, the existing method is to use a forklift to adjust the bucket multiple times to level the material, and manually level the locally uneven positions. The overall work efficiency is low, and it is difficult for the manually leveled positions to have the same looseness as the forklift leveled positions, which may cause pits in the subsequent compaction work.

A connecting plate 17 is fixedly provided on the upper surface of the horizontal plate 5, and a pull rod 12 is connected to the upper end of the connecting plate 17. A connecting member 11 is provided at the upper end of the pull rod 12, and the connecting member 11 can be connected to an external trolley; the first threaded rod 4, the second threaded rod 9 and the third threaded rod 14 are screwed with a fixing nut 18 at the position corresponding to the bottom surface of the horizontal plate 5, and are fixed with the double nut 8; a tension spring 7 is sleeved on the first threaded rod 4, and the lower end of the tension spring 7 is fixedly connected to the horizontal plate 5, and the upper end is hung with the bottom of the double nut 8; the long scraper 6 is arranged at an angle, and the side corresponding to the raised scraper 3 is in a downward pressing state on the material; a wear-resistant head 1 made of wear-resistant metal is provided at the bottom of the first threaded rod 4; a reinforcing rib 13 is provided between the diverter plate 2 and the lower part of the first threaded rod 4; a counterweight block 16 is provided on the upper surface of the horizontal plate 5.

[0019] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0020] According to the instruction manual Figure 1-2It can be seen that when the present invention is used, the connector 11 at the upper end of the pull rod 12 is fixedly connected to the external trolley, and the lower end of the pull rod 12 is fixedly connected to the upper surface of the horizontal plate 5 through the connecting plate 17. The connection here is preferably to ensure that the horizontal plate 5 is level, and the flattening effect will be better. Of course, a slight tilt of the horizontal plate 5 will not affect the use. Figure 2 For example, the trolley pulls the pull rod 12, the connecting plate 17, and the horizontal plate 5 to move to the right. The lower end of the first threaded rod 4 in the front-end limiting hole 15 on the horizontal plate 5 contacts the ground, and the lower diverter plate 2 begins to contact the material. Since the first threaded rod 4 and the diverter plate 2 are evenly distributed, and since the diverter plate 2 is V-shaped with a V-shaped tip at the front end, when it passes through the material, the material will pass through the gap between the two diverter plates 2, causing the material to form strips of protrusions. In other words, the first step of regularizing the distribution of the material is made, so that the material protrusions are evenly arranged. Since the raised scraper 3 at the lower end of the second threaded rod 9 at the center of the horizontal plate 5 corresponds to the gap between the two adjacent diverter plates 2, the raised scraper 3 can scrape the raised material flat, and perform the second step of flattening. Finally, the long scraper 6 at the lower end of the third threaded rod 14 is used to flatten the entire material. The utility model drives the horizontal plate 5 to move by pulling a cart, driving the multiple evenly distributed diverter plates 2 at the front end to divert the material, so that the material forms neat bulges, and the multiple evenly distributed bulge scrapers 3 in the center are used to preliminarily flatten the raised materials, so that the raised materials are diverted to both sides, and finally the entire long scraper 6 at the rear end is used to flatten the entire material, ensuring the flatness of the material along the entire flattening line, with good flattening effect, and the flattening work can be completed after passing through the material once, with high work efficiency.

[0021] Before the above work, the height of the diverter plate 2, the raised scraper 3 and the long scraper 6 can be adjusted by adjusting the double nut 8 and the fixed nut 18, so as to be suitable for flattening materials of different thicknesses. In the above work, it should be understood that the horizontal plate 5 as well as the diverter plate 2, the raised scraper 3 and the long scraper 6 are all of a certain weight, which can ensure that the bottom of the threaded rod touches the bottom. According to common sense, there are gaps between the diverter plates 2, forming bulges, which makes it easier for materials to pass through the long scraper 6. Therefore, the diverter plate 2 will be lower than the long scraper 6. Of course, since the heights of the diverter plate 2, the raised scraper 3 and the long scraper 6 can be adjusted, this design idea can also be obtained through experience in actual use, and will not be elaborated here.

[0022] The first threaded rod 4 is fitted with a tension spring 7, the lower end of which is fixedly connected to the horizontal plate 5 and the upper end of which is attached to the bottom of the double nut 8. The bottom of the first threaded rod 4 vibrates with the height of the road surface, thereby vibrating the diverter plate 2 and improving the diversion effect of the material. Of course, it should be noted that the height of the diverter plate 2 must be adjusted before the tension spring 7 is attached to avoid affecting the rotation of the double nut 8.

[0023] Among them, the long scraper 6 is set at an angle, and the side corresponding to the raised scraper 3 presses down on the material. The main flattening work is that the raised scraper 3 scrapes the raised material flat, and the long scraper 6 mainly plays an optimization role to make the entire surface smoother.

[0024] Among them, a wear-resistant head 1 made of wear-resistant metal material is provided at the bottom of the first threaded rod 4 to improve the service life.

[0025] Among them, a reinforcing rib 13 is provided between the diverter plate 2 and the lower portion of the first threaded rod 4 to increase the connection strength.

[0026] Among them, a counterweight block 16 is provided on the upper surface of the horizontal plate 5, which depends on the actual situation of the material. If the material is thicker and more viscous, more counterweights are added to ensure the working position of the diverter plate 2, the raised scraper 3 and the long scraper 6 to improve the leveling effect.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
