[0002] A scraper grader is a commonly used mechanical equipment in earthwork projects, mainly used for shaping and leveling operations. Scraper graders are widely used in leveling operations on large areas of land such as roads, airports, and farmlands. In roadbed construction, it can provide sufficient strength and stability for the roadbed. In addition, it can also complete a number of tasks such as building slopes, digging ditches, mixing road mixtures, clearing snow, pushing bulk materials, and maintaining dirt roads and gravel roads.

[0003] Among them, the "hydraulic flip leveler" disclosed with the announcement number "CN216087460U" has solved the disadvantages of being relatively single in function and being able to only level the ground but not to push or pull soil. However, the above-mentioned hydraulic flip scraper leveler drives the flipping of the arc plate through multiple sets of hydraulic cylinders. Due to the delay in the supply of hydraulic oil, the extension and retraction of the multiple sets of hydraulic cylinders will be incompletely synchronized, resulting in the stretching and skewing of the arc plate, causing the arc plate to deform and affecting the flipping of the arc plate. Therefore, it is necessary to design a hydraulic flip scraper leveler. Utility Model Content

The end of the support arm 102 is movably connected to the scraper 2. The scraper 2 and the support arm 102 are movably installed through a movable shaft 201. The support arm 102 can be used to rotatably support the two end positions of the scraper 2, which can improve the stability of the scraper 2 when it is flipped. The support assembly 1 also includes a reinforcement rod 103 and a connecting ear 104. The base frame 101 is fixedly connected to the reinforcement rod 103, and the structural strength of the base frame 101 can be improved by the reinforcement rod 103. , it can be a case where the chassis 101 can bear a large load and is not easy to deform. A connecting ear 104 is fixedly installed at the rear end of the chassis 101, and the support assembly 1 can be docked and installed with the grader through the connecting ear 104. A sleeve 301 is fixedly installed on the inner side of the chassis 101, and a supporting leg 3 is sleeved at the bottom of the sleeve 301. The supporting leg 3 passes through the sleeve 301, and can slide up and down inside the sleeve 301 through the supporting leg 3. At the same time, the supporting leg 3 and the sleeve 301 are fixed by a fixing pin, which can conveniently fix the supporting leg 3 at a suitable height. The supporting leg 3 can support the supporting assembly 1, and can be conveniently placed at a suitable position on the ground when not in use, in conjunction with the scraper 2, so that the device is not easy to tip over;

[0022] A fixing assembly 5 is provided on the top of the base frame 101, and a driving assembly 4 is movably connected to the inner side of the base frame 101. The number of driving assemblies 4 is a single group. By replacing multiple hydraulic cylinders with a single group of driving assemblies 4, the flipping of the scraper 2 can be driven by a single driving assembly 4, which can effectively avoid the situation that the extension and retraction of multiple groups of hydraulic cylinders are not synchronized when the hydraulic oil supply is unstable, thereby avoiding the impact on the flipping of the scraper 2. One end of the driving assembly 4 is movably connected to the fixing assembly 5, and the other end of the driving assembly 4 is movably connected to the scraper 2. The driving assembly 4 includes a push-pull rod 401, a hydraulic telescopic rod 402, a movable rod 403 and an movable rod 404. The movable seat 404 is fixedly installed on the top of the base frame 101, and a movable rod 403 is movably connected to one side of the movable seat 404. A push-pull rod 401 is movably connected between the movable rod 403 and the scraper 2. The scraper 2 and the push-pull rod 401 are movably connected through an active joint 202. The push-pull rod 401 and the scraper 2 can be moved accordingly through the active joint 202. A hydraulic telescopic rod 402 is movably installed between the movable rod 403 and the fixed component 5. The fixed component 5 includes a fixed frame 501 and an inclined frame 502. The fixed frame 501 is fixedly installed on the top of the base frame 101. The fixed frame 501 and the hydraulic telescopic rod 402 are connected. The hydraulic telescopic rod 402 is movably connected by a hinge, so that the hydraulic telescopic rod 402 can rotate accordingly when it is extended and retracted. The fixed frame 501 and the base frame 101 are fixedly connected with an inclined frame 502.

At the same time, the inclined frame 502 can be used to protect both sides of the hydraulic telescopic rod 402, which can effectively prevent the hydraulic telescopic rod 402 from colliding with external objects during the construction process. When the hydraulic telescopic rod 402 is retracted, one end of the movable rod 403 can be pulled to When the movable rod 403 is flipped upward, the push-pull rod 401 can be pulled to move upward synchronously. The push-pull rod 401 can be used to pull the scraper 2 to flip around the axis of the movable shaft 201, so that the scraper 2 can be flipped conveniently, and the scraper 2 can be used for scraping soil conveniently. The scraper 2 is a special plate formed by bending an arc shape, which is more resilient. When the hydraulic telescopic rod 402 is extended, one end of the movable rod 403 can be pushed to flip downward, and the push-pull rod 401 can be pushed to move downward, so that the scraper 2 can be pushed to flip downward around the axis of the movable shaft 201, and the flipping angle of the scraper 2 can be conveniently adjusted according to usage requirements.

[0023] The working principle of the hydraulic flip scraper and grader based on the embodiment is: the support component 1 can be docked and installed with the grader through the connecting ear 104, the overall structural strength can be improved through the fixing component 5, so that the support component 1 is not prone to shaking and deformation during use, and the movable rod 403 can be pulled to flip upward when the hydraulic telescopic rod 402 is contracted, and the scraper 2 can be pulled to flip upward by the push-pull rod 401. When the hydraulic telescopic rod 402 is extended, the scraper 2 can be pushed to flip downward by the push-pull rod 401, and the flipping angle of the scraper 2 can be adjusted according to usage requirements. The scraper 2 can be stably controlled by a single driving component 4, and the two ends of the scraper 2 can be stably supported by the support arm 102. After the scraper 2 is flipped upward, the soil scraping operation can be performed through the bottom end of the scraper 2, and after the scraper 2 is flipped downward, the soil leveling operation can be performed by using the movement of the grader.
