Description

Technical Field

[0001] This utility model relates to the technical field of graders, and in particular to a grader scraper adjustment device. Background Technology

[0002] Graders are key machines used in earthmoving projects for ground leveling operations, and are widely used in highway construction, site leveling, farmland improvement, and other fields. Their core working component is the scraper adjustment device, which achieves precise scraping and leveling of the ground by adjusting the angle, height, and working direction of the scraper.

[0003] Traditional graders typically use rigid connection structures for their blade adjustment devices, resulting in a limited range of adjustment methods that are difficult to adapt to the operational needs of complex terrains (such as slopes, undulating surfaces, or irregular areas). For example, existing devices have a limited angle adjustment range, and directional adjustment relies on the movement of the entire machine, leading to low construction efficiency and insufficient leveling accuracy.

[0020] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] The grader scraper adjustment device of this utility model embodiment will be described below with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, the grader scraper adjustment device of this utility model embodiment includes:

[0023] Mounting bracket 1.

[0024] The support beam 2 has one end hinged to the mounting frame 1 via a hinge shaft 6.

[0025] The hydraulic telescopic pump 7 has one end hinged to the mounting frame 1 and the other end hinged to the support beam 2.

[0026] Turntable 4 is fixed to the end of support beam 2 away from hinge shaft 6. Turntable 4 is rotatably connected to slewing bearing 8. The central shaft of slewing bearing 8 is connected to leveling frame 5. Meshing gear 9 is rotatably connected to turntable 4. Meshing gear 9 is meshed with slewing bearing 8. Turntable 4 is equipped with drive motor 10. The output end of drive motor 10 is connected to the central shaft of meshing gear 9. Leveling scraper 3 is provided on the inner side of leveling frame 5.

[0027] In this embodiment of the grader blade adjustment device, the mounting frame 1 is used for overall installation and fixation. The support beam 2 is connected to the mounting frame 1 via a hinge shaft 6, and its angle can be adjusted under the drive of the hydraulic telescopic pump 7 to achieve height and tilt adjustment of the grader frame 5. The turntable 4 is mounted on the end of the support beam 2, and through the cooperation of the drive motor 10 and the meshing gear 9, it drives the grader frame 5 to rotate via the slewing bearing 8 to adjust the working direction of the grader blade 3. The grader blade 3 on the inner side of the grader frame 5 is adjusted according to the angle and direction of the device to achieve the leveling operation of the ground.

[0028] Angle adjustment: The support beam 2 is driven to rotate around the hinge shaft 6 by the hydraulic telescopic pump 7, which can adjust the soil penetration depth and tilt angle of the leveling scraper 3 to adapt to different terrains, such as the leveling needs of slopes and potholes, and improve the accuracy of operation.

[0029] Direction adjustment: The drive motor 10 drives the slewing bearing 8 through the meshing gear 9, so that the turntable 4 and the flat frame 5 rotate as a whole, realizing the 360° rotation of the scraper 3 in the working direction. It can cover a larger working area without moving the whole machine, and is especially suitable for flexible construction in irregular areas.

[0030] Synergistic adjustment: The linkage between angle and direction adjustment allows the scraper 3 to maintain the best cutting posture in complex terrains, such as bends and ditch edges, reducing repetitive work and improving construction efficiency and surface smoothness.

[0031] In one embodiment of this utility model, the flat platform 5 is an arc-shaped plate structure, and the working surface of the arc-shaped plate faces the ground.

[0032] Specifically, the leveling frame 5 adopts an arc-shaped plate structure, with its arc-shaped working surface facing the ground. During operation, the arc-shaped contour naturally conforms to the ground, achieving uniform leveling. This design effectively reduces the height difference of the working surface, making the ground smoother after leveling. It is especially suitable for continuous operation on undulating terrain, improving leveling efficiency and leveling accuracy.

[0033] In one embodiment of the present invention, a sliding block 13 is provided on the inner side of the leveling frame 5, and a slider 12 adapted to the sliding block 13 is provided on the outer side of the leveling scraper 3.

[0034] Specifically, the leveling frame 5 and the leveling scraper 3 are fixed together by bolts, and the sliding block 13 and the slider 12 facilitate the replacement of the leveling scraper 3.

[0035] In one embodiment of the present invention, the support beam 2 is provided with side beams 11 on both sides, and the side beams 11 are fixedly connected to the support beam 2.

[0036] Specifically, the side beam 11 and the support beam 2 form a triangular stable frame, which effectively resists the lateral force and torque on the leveling scraper 3 during operation, reduces the bending deformation of the support beam 2, and improves the overall structural stability.

[0037] In one embodiment of the present invention, the cross-section of the sliding block 13 is a T-shaped groove structure, and the slider 12 is a T-shaped protrusion adapted to the T-shaped groove.

[0038] Specifically, it is used for replacing the leveling scraper 3 in the T-slot.

[0039] The working process of the grader scraper adjustment device in this embodiment is as follows:

[0040] Mounting frame 1 is fixed to the main body of the grader. Support beam 2 is connected to mounting frame via hinge shaft 6. When hydraulic telescopic pump 7 extends or retracts, it drives support beam to rotate around hinge shaft, adjusting the height and tilt angle of grader frame 5 so that the soil penetration depth and cutting angle of grader scraper 3 are adapted to the terrain such as slopes and potholes.

[0041] The drive motor 10 drives the slewing bearing 8 to rotate through the meshing gear 9, and the turntable 4 and the flat frame 5 rotate synchronously, realizing 360° adjustment of the working direction of the scraper 3, so that irregular areas can be covered without moving the whole machine.

[0042] The working surface of the arc-shaped leveling frame 5 is in contact with the ground. During scraping, the arc-shaped contour evenly smooths the ground, reducing height differences. The scraper 3 slides in the T-slot of the slide block 13 via the slider 12, allowing for lateral fine-tuning of the working position or quick replacement to adapt to different leveling width requirements.

[0043] The side beam 11 and the support beam 2 form a stable frame to withstand the lateral force during scraper operation, ensuring structural stability during adjustment and improving overall reliability.

[0044] In summary, the grader blade adjustment device of this utility model, through multi-dimensional adjustment and structural design, can flexibly adapt to the grading needs of different terrains, improving ground leveling accuracy and construction efficiency. It also facilitates blade position adjustment and replacement, enhancing the device's practicality and maintenance convenience, and is suitable for long-term heavy-duty working conditions.
