[0004] Although the design can facilitate the adjustment of the height and angle of the leveling floor, thus improving the convenience of using the motor grader, facilitating the installation and disassembly of the leveling floor, and improving the convenience of disassembly of the leveling floor, the device only relies on the power of the vehicle body to perform the leveling work. When the vehicle body finds it difficult to continue moving forward when encountering a hard bump, it is necessary to adjust the position of the vehicle body and continue the leveling work. Adjusting the direction of the vehicle body will consume time, affecting the progress of the construction.

[0005] In order to solve the above problems, the present application proposes a motor grader for road engineering. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] like Figure 1 As shown:

[0024] A motor grader for road engineering comprises a vehicle body 1.

[0025] In this embodiment: the existing {publication (announcement) number}: CN217479900U discloses a quantitative grader for road engineering. This patent discloses a leveling floor. The shovel head 10 in the present application document adopts the same technical means in this prior art. This technical means will not be described one by one here. For details about the improvement of this prior art, please refer to the disclosed technology below; to solve the technical problems existing in this prior art, as disclosed in the background technology above, "the device only relies on the power of the vehicle body 1 to level the ground when performing leveling work, and when the vehicle body 1 encounters a hard bump and is difficult to continue moving forward, it is necessary to adjust the position of the vehicle body 1 and continue to level the ground. When adjusting the direction of the vehicle body 1, time will be consumed, affecting the progress of construction." In terms of combined use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve the above problem, a bracket 2 and a leveling bin 3 are added on this basis.

[0026] More specifically:

[0027] like Figure 1-Figure 4 As shown:

[0028] In combination with the above content: it also includes a bracket 2, a leveling bin 3, a motor 4, a connecting shaft 5, a transmission rod 6, a push block 7, a slider 8, a spring 9 and a shovel head 10 arranged on one side of the vehicle body 1. The bracket 2 is fixedly installed on one side of the vehicle body 1, and one side of the bracket 2 is fixedly connected to the surface of the leveling bin 3, and the motor 4 rotatably connected to the transmission rod 6 is also fixedly installed on the surface of one side of the leveling bin 3. At the same time, the surface of the transmission rod 6 is also rotatably connected to the connecting shaft 5 fixedly arranged on the surface of the leveling bin 3. The surface of the transmission rod 6 is also fixedly installed with a push block 7 slidably connected to the slider 8, and the slider 8 is slidably connected to the inner surface of the leveling bin 3 and is also fixedly connected to one end of the spring 9, and the other end of the spring 9 is fixedly connected to the inner surface of the leveling bin 3, and at the same time, one side of the slider 8 also forms an integrated structure with the shovel head 10.

[0029] When the vehicle body 1 is started and leveling work is performed, the motor 4 located on one side of the leveling bin 3 can be started. At this time, the motor 4 will drive the transmission rod 6 and the push block 7 arranged on one side thereof to rotate along the connecting shaft 5. When the push block 7 rotates, it will slide with the slider 8 and generate thrust on the slider 8, thereby pushing the slider 8 and the shovel head 10 to slide inside the leveling bin 3. When the push blocks 7 arranged perpendicular to each other rotate, each adjacent shovel head 10 will move in different directions. When the longer end of the push block 7 is connected to the slider 8, the shovel head 10 will be pushed to move and compress the spring 9. When the shorter side of the push block 7 is connected to the slider 8, the shovel head 10 will be driven to reset under the rebound of the spring 9. During this process, the vehicle body 1 always keeps in a running state, so that the shoveling efficiency can be efficiently accelerated through the shovel head 10 when the vehicle body 1 is performing production work.

[0030] Going further:

[0031] In an optional embodiment, grooves matching the slide blocks 8 are formed at equal intervals on the inner surface of the flat-floor bin 3 .

[0032] In this embodiment, the grooves that are equidistantly arranged and match the slider 8 can provide the slider 8 with a stable and sufficient activity space, can enable the slider 8 and the shovel head 10 to produce stable activity work, and can also provide a favorable space for the contraction of the spring 9.

[0033] Going further:

[0034] In an optional embodiment, the transmission rod 6 is cylindrical in shape, and a through hole matching the transmission rod 6 is formed on the surface of the connecting shaft 5 .

[0035] In this embodiment: the cylindrical transmission rod 6 and the connecting shaft 5 with a through hole can make the transmission rod 6 rotate along the axis of the connecting shaft 5, have high stability, and can also effectively and stably drive the push block 7 to rotate.

[0036] Going further:

[0037] In an optional embodiment, the push block 7 is elliptical in shape, and the push block 7 and its adjacent push block 7 are arranged perpendicular to each other.

[0038] In this embodiment, the push blocks 7 that are perpendicular to each other and staggered can drive the adjacent shovel heads 10 to move in different directions when the transmission rod 6 drives the push blocks 7 to rotate, thereby achieving the purpose of driving the shovel heads 10 to produce staggered movements.

[0039] Going further:

[0040] In an optional embodiment, the springs 9 are symmetrically arranged on both sides of the slider 8 .

[0041] In this embodiment: the symmetrically arranged springs 9 can stabilize the slider 8 when the slider 8 moves, so that the staggered operation of the slider 8 and the shovel head 10 can be performed more efficiently and flexibly.

[0042] Going further:

[0043] In an optional embodiment, the shovel head 10 is arc-shaped, and the shovel head 10 is equidistantly arranged at the bottom of the leveling bin 3 .

[0044] In this embodiment: the arc-shaped shovel head 10 can smoothly remove the protrusions on the ground when the vehicle body 1 moves, and the equidistantly arranged shovel heads 10 can speed up the removal of hard protrusions on the ground during staggered operation, which can make the leveling work go more smoothly.

[0045] When the vehicle body 1 is started and leveling work is performed, the motor 4 located on one side of the leveling bin 3 can be started. At this time, the motor 4 will drive the transmission rod 6 and the push block 7 arranged on one side thereof to rotate along the connecting shaft 5. When the push block 7 rotates, it will slide with the slider 8 and generate thrust on the slider 8, thereby pushing the slider 8 and the shovel head 10 to slide inside the leveling bin 3. When the push blocks 7 arranged perpendicular to each other rotate, each adjacent shovel head 10 will move in different directions. When the longer end of the push block 7 is connected to the slider 8, the shovel head 10 will be pushed to move and compress the spring 9. When the shorter side of the push block 7 is connected to the slider 8, the shovel head 10 will be driven to reset under the rebound of the spring 9. During this process, the vehicle body 1 always keeps in a running state, so that the shoveling efficiency can be efficiently accelerated through the shovel head 10 when the vehicle body 1 is performing production work.

[0046] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
