Detailed Description

It should be understood that these embodiments are merely illustrative of the present invention and are not intended to limit the scope of the invention, and that various changes and modifications may be made by those skilled in the art after reading the teachings of the present invention and these equivalents also fall within the scope of the invention as defined in the present application.

Example 1:

the utility model discloses an guide tracked level land mechanical structure, major structure include the guide rail mechanism 1 of both sides and the leveler mechanism 2 between the guide rail mechanism 1 of both sides, leveler mechanism 2 removes along guide rail mechanism 1, guide rail mechanism 1 carries out the width setting according to the road width, leveler mechanism 2 sets gradually flat push pedal 3, big compression roller 4 and smoothing roller 5 from the front to the back, big compression roller 4, smoothing roller 5 rotate and are connected on guide rail mechanism 1, the smoothing roller 5 end is equipped with driving motor 6, flat push pedal 3 is at the forefront, at first pushes up unevenness concrete road surface or bituminous pavement or sand and soil road surface etc. and nevertheless, the road surface is very loose after the flat push pedal 3 pushes up the road surface, so follow-up big compression roller 4 just will loose road surface compaction, smoothing roller 5 also can play the compaction effect of advancing step, but the main effect of smoothing roller 5 is to grind the road surface after the compaction, constantly rotatory smoothing roller 5 can be with the surface seam, push up and fill and grind the flat through the process.

, in order to ensure better compacting and grinding effects after flattening, the following two improvements are needed, which will be explained in detail with reference to fig. 3 of the accompanying drawings:

th, the bottommost end of the flat push plate 3 is higher than the bottommost end of the large press roller 4, so that the height difference is the preset flattening thickness, the height difference h2 keeps 5-20 mm, and the height difference can be adjusted adaptively according to the actual flattened pavement.

Secondly, layers of soft rubber layers are arranged on the surface of the leveling roller 5, the bottom end of each soft rubber layer is lower than the bottom end of the large pressing roller 4, each soft rubber layer has elastic deformation capacity of , achieves a damping effect of , and is difficult to rust compared with a metal surface.

The adaptability adjusting modes are various, the adaptability adjusting can be realized through a base plate and various telescopic mechanism winds, the problem is not difficult for technical personnel in the mechanical field, the problem is not a main protection point, and the construction mechanism which is used for realizing flat ground work through three procedures of flattening, compacting and grinding for times is mainly protected.

Step is clear that under , the driving motor 6 can be a servo motor or a hub motor, the two motors have respective advantages and disadvantages, and a common servo motor with low cost is selected in .

The connection modes of the large compression roller 4, the smoothing roller 5, the ground pushing plate 3 and the guide rail mechanism 1 are as follows:

the guide rail mechanism 1 includes a guide portion 7 and a movable portion 8. The movable part 8 is provided with a front bearing seat 9 and a rear bearing seat 10, the two ends of the large compression roller 4 are fixed on the movable part 8 through the front bearing seat 9, and the leveling roller 5 is fixed on the movable part 8 through the rear bearing seat 10. The two sides of the flat push plate 3 are provided with connecting frames 11, and the two sides of the flat push plate 3 are fixed on the movable part 8 through the connecting frames 11. Which is a very conventional and common principle of the connection mechanism and will not be described in detail here. The cambered plate 12 at the top end of the flat push plate 3 is used for preventing the bulldozer from falling between the flat push plate 3 and the large press roller 4 beyond the top end of the flat push plate 3.

Finally, as for the guide rail mechanism 1,

the structural principle explanation of embodiment 1 under is made here:

the guide rail mechanism 1 is a rodless cylinder mechanism, the guide part 7 is a guide rail of a rodless cylinder, and the movable part 8 is a sliding block of the rodless cylinder. The advantage of rodless cylinders is that they operate smoothly and accurately, which is not a major consideration for flat ground applications, but they are also advantageous because they relate to the flatness of the road surface for both the flattening and troweling processes. The defects are obvious, the guide rail needs to be kept clean, and the maintenance work is complicated.

Example 2:

, the structural principle of the embodiment 2 is explained in the specification that the guide rail mechanism 1 is a screw and nut transmission mechanism, the guide part 7 is a transmission screw, and the movable part 8 is a driven nut, the screw and nut transmission mechanism has poor stability in use, particularly vibration caused by the rotation of the screw driven by an electrode is caused by the large vibration caused by the large power motor required for driving the whole mechanism to translate, but the guide rail mechanism 1 is used for urban back streets and alleys with low requirements, and has low cost and small maintenance difficulty.

To summarize:

the land leveling mechanism 2 is sequentially provided with a land leveling push plate 3, a large compression roller 4 and a leveling roller 5 from front to back, the land leveling push plate 3 is arranged at the forefront, firstly, uneven concrete pavement, asphalt pavement or sandy soil pavement and the like are leveled, after the land leveling push plate 3 flattens the pavement, the subsequent large compression roller 4 compacts loose pavement, the leveling roller 5 is driven by a driving motor 6 to grind the compacted pavement flat, the constantly rotating leveling roller 5 can grind the surface road joints and perform the filling and grinding through the grinding process, shows that the land leveling work can be realized through three processes of leveling, compacting and grinding in times in sequence, the ground is more tightly combined after compacting and grinding, and if the surface has road joints, the land can be filled and ground through the grinding process.
