Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] like Figure 1-3 As shown, the present invention proposes a wide-width grader, which includes a mounting frame 1, a mounting plate 2 fixedly connected to one side of the mounting frame 1, and a scraper assembly 3 for grading the ground disposed inside the mounting frame 1.

[0027] In this invention, the leveling width can be adjusted according to the leveling requirements when leveling the field using the scraper assembly 3.

[0028] In an optional embodiment, the scraper assembly 3 includes a support plate 38 slidably connected to the inner side of the mounting frame 1. A support column 31 is rotatably connected to one side of the support plate 38. An electric push rod 32 is fixedly installed on the support column 31. A central scraper 33 is fixedly connected to the end of the support column 31 away from the mounting frame 1. Support scrapers 35 are fixedly connected to both sides of the central scraper 33, and the support scrapers 35 are fixedly connected to the support column 31. An adjusting scraper 34 is slidably connected to the outer side of the support scraper 35. An adjusting rod 37 with one end hinged to the output end of the electric push rod 32 is connected to the adjusting scraper 34. A limiting post 36 with one end penetrating the support column 31 is fixedly connected to the side of the mounting plate 2 near the central scraper 33.

[0029] In this embodiment, when the adjusting scraper 34 located on the two supporting scrapers 35 is pushed and adjusted by the electric push rod 32 through the adjusting rod 37, it can adjust the width of the central scraper 33, the supporting scraper 35 and the adjusting scraper 34 in the overall connected state, thereby meeting the leveling needs of fields with different widths and improving the leveling efficiency of the entire grader.

[0030] It should be noted that the lower end of the adjusting scraper 34 is provided with a groove for the adjusting scraper 34 to slide on the supporting scraper 35. The supporting scraper 35 is provided with a sliding groove 311 on the side near the mounting bracket 1. A slider 310 with one end extending to the inside of the sliding groove 311 is fixedly connected to the inner side of the adjusting scraper 34, and the slider 310 is slidably connected to the sliding groove 311. Through the sliding support of the slider 310 and the sliding groove 311, the adjusting scraper 34 can be stably slidably adjusted on the supporting scraper 35 without separating from the supporting scraper 35.

[0031] The connection between the support column 31 and the central scraper 33 and the support scraper 35 is in the shape of a mountain, which enables the support column 31 to stably support the central scraper 33 and the support scraper 35. A support rod 39 with one end penetrating through the support plate 38 is fixedly connected to the inner top wall of the mounting frame 1. Through the support rod 39 penetrating through the support plate 38 and the limiting column 36 penetrating through the support column 31, the support column 31 is more stable when it is raised and lowered.

[0032] In an optional embodiment, the mounting plate 2 is provided with a lifting assembly 4 for adjusting the lifting of the support column 31; the lifting assembly 4 includes an electric telescopic rod 41 fixedly connected to the inner side of the mounting frame 1, the output end of the electric telescopic rod 41 is fixedly connected to a connecting block 42, a support block 45 located between the electric push rod 32 and the central scraper 33 is rotatably connected to the support column 31, and a top rod 43 is hinged between the lower end of the support block 45 and the connecting block 42.

[0033] In this embodiment, when the activated electric telescopic rod 41 drives the connecting block 42 to move horizontally, the hinged top rod 43 can lift the support column 31 to rise. Conversely, when the retracted electric telescopic rod 41 retracts the top rod 43 through the connecting block 42 to lower the support column 31, so as to realize the lifting and lowering adjustment of the support column 31 and the central scraper 33.

[0034] It should be noted that the connecting block 42 is rotatably connected to the support column 31 via a bearing. A guide rod 44 with one end passing through the connecting block 42 is fixedly connected to the mounting plate 2. The support plate 38 has a support groove for the support column 31 to rotate on the side near the support column 31. The support groove is cylindrical. The end of the support column 31 located inside the support groove is also rotatably connected via a bearing, so that the support column 31 can be rotated and adjusted, and can also be pushed, pulled and raised by the push rod 43.

[0035] In an optional embodiment, the support plate 38 and the central scraper 33 are provided with an adjustment component 5 for adjusting the horizontal position of the central scraper 33; the adjustment component 5 includes a motor 52 fixedly connected to the support plate 38, and the output shaft of the motor 52 and the end of the support column 31 near the support plate 38 are both fixedly connected with meshing gears 53, and a level 51 is fixedly installed above the central scraper 33.

[0036] In this embodiment, the level of the central scraper 33, the support column 31 is adjusted by the level 51 on the central scraper 33, which in turn drives the starting motor 52 through two meshing gears 53 during the rotation adjustment process. The level of the central scraper 33, the support scraper 35 and the adjustment scraper 34 can be adjusted by the rotation of the support column 31.

[0037] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Since this utility model is mainly used to protect mechanical structures, the control method and circuit connection and other technical means will not be described in detail here.

[0038] The working principle in the above embodiments is as follows:

[0039] After the central scraper 33, the support scraper 35, and the adjusting scraper 34 are fixed to the mounting bracket 1 with conventional bolts, the connecting block 42 can be moved horizontally by the telescopic electric telescopic rod 41. The support column 31 is raised or lowered by the top rod 43 to drive the central scraper 33, the adjusting scraper 34, and the support scraper 35 to adjust their height to fit the field that needs to be leveled.

[0040] During the leveling process, the adjusting scraper 34 located on the two supporting scrapers 35 is adjusted by the adjusting rod 37 driven by the electric push rod 32. This adjusts the distance between the two adjusting scrapers 34, thereby adjusting the width of the central scraper 33, supporting scraper 35 and adjusting scraper 34 in the overall connected state, so as to meet the leveling needs of fields with different widths. Since the end of the support column 31 near the support plate 38 is rotatably supported on the support plate 38, and a level 51 is set above the central scraper 33, the levelness of the central scraper 33 can be adjusted by observation and by the level 51, as well as by the motor 52 and gear 53, so that the overall leveling of the central scraper 33, supporting scraper 35 and adjusting scraper 34 is more even.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
