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

[0022] like Figures 1 to 5 As shown, this embodiment proposes a new multifunctional grader, including a body 1, a support frame 2 is provided at the bottom of the body 1, one end of the support frame 2 is rotatably connected to the body 1, a lifting structure is provided between the support frame 2 and the body 1, a steering structure is provided on one side of the support frame 2, a leveling shovel 3 is provided on the side of the steering structure facing away from the body 1, a cutting blade 4 is provided on the side of the leveling shovel 3 facing away from the steering structure, a cutting head 42 is provided on one side of the cutting blade 4, a rotating shaft 41 is provided on the side of the cutting blade 4 facing away from the cutting head 42, the rotating shaft 41 is rotatably connected to the leveling shovel 3, a rotating structure for rotating the cutting blade 4 is provided on the support frame 2, and a planing shovel 6 is provided on the rear side of the body 1.

[0023] The support frame 2 is used to support and connect the leveling blade 3 and related components, and can adjust the height and angle. The lifting structure is used to adjust the height of the support frame 2 and the components thereon; the height of the leveling blade 3 can be flexibly adjusted to adapt to different terrain conditions and improve the leveling effect. The lifting structure of this embodiment can adopt hydraulic lifting. The rotating structure is used to adjust the direction of the leveling blade 3, provide flexible operating capabilities, enhance the maneuverability and flexibility of the equipment, and enable the grader to operate efficiently in narrow and complex terrain. The leveling blade 3 is used for leveling and bulldozing operations on the ground, realizing the leveling and bulldozing functions of the ground. The cutting blade 4 is used to cut vegetation roots, which can effectively solve the problem of vegetation roots hindering the leveling effect and improve the efficiency and quality of leveling operations. The cutting head 42 is used to cut vegetation and roots with the assistance of the cutting blade 4, enhance the cutting ability, enable the equipment to efficiently handle ground vegetation, and avoid the problem of root entanglement. The rotating shaft 41 is used to connect the cutting blade 4 and the leveling blade 3, so that the cutting blade 4 can rotate. The rotary mechanism drives the rotary shaft 41 and cutting blade 4 to perform rotary cutting. The rotary mechanism provides power and control, ensuring that the cutting blade 4 remains stably connected to the leveling blade 3 during use, effectively processing vegetation and roots. When cutting is not required, the cutting blade 4 can be rotated to the rear of the leveling blade 3, reducing wear and tear on the cutting blade 4 and the need for maintenance, extending its service life and lowering operating costs. The planing blade 6 is used to further plan and level the ground. After the leveling blade 3 has initially leveled the ground, the ground is finely processed to enhance the final leveling effect and construction quality.

[0024] In this embodiment, the cutting head 42 includes a plurality of pointed protrusions, which are arranged linearly along the cutting head 42. An inclined surface is provided on the side of the pointed protrusion facing the leveling shovel 3. The inclined surface is inclined from the side of the pointed protrusion close to the leveling shovel 3 to the side of the cutting blade 4 away from the rotating shaft 41. The cross-section of the pointed protrusion has a triangular structure. The pointed protrusion is used to assist in cutting and dividing vegetation. The pointed protrusion can be inserted into thicker rhizomes to divide the thicker rhizomes. The inclined surface of the pointed protrusion enables the cutting head 42 to more easily cut into and divide the roots of vegetation, while reducing resistance and improving cutting efficiency. The inclined surface can also help push the cut vegetation to one side to prevent it from piling up on the cutting head 42. The pointed protrusion with a triangular cross-section can provide a sharp cutting edge; the triangular cross-section provides a sharper cutting angle, enabling the cutting head 42 to more effectively cut the roots of vegetation and reduce cutting resistance and wear.

[0025] In this embodiment, the rotating structure includes a drive motor 5 and a transmission structure. The drive motor 5 is located on the side of the leveling blade 3 facing away from the cutting head 42. The drive motor 5 is fixedly connected to the support frame 2. The transmission structure is connected to the drive motor 5 and the rotating shaft 41. The drive motor 5 drives the rotating shaft 41 through the transmission structure. The drive motor 5 is used to drive the rotating shaft 41 to rotate, thereby achieving the flipping of the cutting blade 4. The transmission structure is used to efficiently transmit the power of the drive motor 5 to the rotating shaft 41.

[0026] In this embodiment, the transmission structure includes a synchronous belt 51 and two synchronous pulleys 52. The two synchronous pulleys 52 are fixedly connected to the drive motor 5 and the rotating shaft 41, respectively. The synchronous belt 51 is mounted on the two synchronous pulleys 52. The synchronous belt 51 and the synchronous pulleys 52 are used to achieve power transmission. The transmission method of the synchronous belt 51 and the synchronous pulleys 52 has the advantages of no slip, a constant transmission ratio, and low noise. It can achieve precise power transmission and ensure stable rotation of the cutting blade 4.

[0027] In this embodiment, a baffle 21 is provided on the side of the leveling blade 3 facing away from the cutting head 42. The baffle 21 is fixedly connected to the support frame 2, and the drive motor 5 is located between the baffle 21 and the leveling blade 3. The baffle 21 protects the leveling blade 3 and the support structure; it prevents debris and vegetation generated during the cutting process from interfering with the drive motor 5, ensuring stable operation of the drive motor 5 and extending the life of the equipment.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
