[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0022] like Figure 1 、 Figure 2 As shown, the utility model provides an adjustable blade of a motor grader, comprising a flat trolley 1, a connecting arm 2 being fixedly mounted on the front side of the flat trolley 1, an adjusting blade mechanism 3 being provided below the connecting arm 2, the adjusting blade mechanism 3 comprising two hydraulic push rods 31, the two hydraulic push rods 31 being fixedly mounted on the left and right sides of the connecting arm 2, a fixed hanging plate 32 being fixedly mounted on the output ends of the two hydraulic push rods 31, the fixed hanging plate 32 being located below the connecting arm 2, a forklift blade 33 being provided below the fixed hanging plate 32, and a slope repair mechanism 34 being provided on the right side of the rear end of the forklift blade 33;
[0023] When the trolley 1 is started to level the ground, the connecting arm 2 is driven to move forward and oil is injected into the two hydraulic push rods 31 at the same time, thereby driving the fixed hanging plate 32 to descend until the forklift blade 33 touches the ground and stops. The forklift blade 33 can be used to scrape off excess sand and soil on the edge of the road during the forward movement of the trolley 1. When not in use, the hydraulic push rod 31 only needs to drive the fixed hanging plate 32 to rise to lift the forklift blade 33 off the ground, making it convenient for the trolley 1 to travel quickly.
[0024] like Figure 3 、 Figure 4 As shown, a motor slot 321 is provided at the center of the bottom circle of the fixed hanging plate 32, and a servo motor 322 is fixedly installed in the inner cavity of the motor slot 321, and a turntable 323 is fixedly installed on the output shaft of the servo motor 322, and the top of the turntable 323 overlaps with the bottom of the fixed hanging plate 32, and a translation adjustment box 324 is fixedly installed on the bottom of the turntable 323, and a fixed hanging plate 331 is fixedly installed in the middle of the rear side of the forklift blade 33, and a connecting slider 332 is fixedly installed on the top of the fixed hanging plate 331, and a hydraulic push rod 3241 is fixedly installed on the left side of the inner cavity of the translation adjustment box 324, and the output end of the hydraulic push rod 3241 is fixedly connected to the left side of the connecting slider 332, and the front and rear sides of the connecting slider 332 are respectively overlapped with the front and rear sides of the inner wall of the translation adjustment box 324;
[0025] When encountering a curve, the servo motor 322 in the motor slot 321 opened at the bottom of the fixed hanging plate 32 is started to drive the turntable 323 to rotate clockwise by a certain angle, so that the right end of the forklift blade 33 at the bottom of the turntable 323 is tilted backward by a certain angle, so that the forklift blade 33 can adapt to different road conditions, and the scraped mud and sand can be directly discharged to the road slope. The hydraulic push rod 2 3241 in the translation adjustment box 324 is oiled to drive its output end to drive the connecting slider 332 to move to the left in the translation adjustment box 324. The fixed connection between the connecting slider 332 and the top of the fixed hanging plate 331 can drive the entire forklift blade 33 to drive the extended sliding slope repair scraper 345 to move to the left until it fits the road slope sand, thereby improving the applicability of the sliding slope repair scraper 345 to different road slopes.
[0026] like Figure 5 As shown, the slope repair mechanism 34 includes a base plate 341, which is fixedly mounted on the right side of the rear end of the forklift blade 33. A limit box 342 that passes through the base plate 341 is fixedly mounted at a forty-five-degree angle on the rear side. A hydraulic cylinder 343 is fixedly mounted on the rear side of the limit box 342. A connecting plate 344 is fixedly mounted on the output end of the hydraulic cylinder 343. A sliding slope repair scraper 345 is fixedly mounted on the front side of the connecting plate 344. The bottom end of the sliding slope repair scraper 345 passes through the bottom of the limit box 342 and is slidably connected to the inner cavity of the limit box 342.
[0027] By starting the hydraulic cylinder 343 on the rear side of the limit box 342 on the rear side of the base plate 341, thereby driving its conveying end to retract, the fixed connection between the connecting plate 344 and the sliding slope-repairing scraper 345 and the sliding of the sliding slope-repairing scraper 345 and the inner cavity of the limit box 342 can be utilized to make the sliding slope-repairing scraper 345 tilt and move downward to the side slope. In conjunction with the forward movement of the flat push cart 1, the sliding slope-repairing scraper 345 on the rear side of the forklift blade 33 can be used to trim the road side slope, so that the sand on the edge of the road can be pushed horizontally while trimming the side slope.
[0028] The following is a detailed description of the working principle of the adjustable blade of the grader.
[0029] like Figure 1-5As shown, when the flat trolley 1 is started to level the ground, the connecting arm 2 is driven to move forward and oil is injected into the two hydraulic push rods 31 at the same time, thereby driving the fixed hanging plate 32 to descend until the forklift blade 33 touches the ground and stops. The forklift blade 33 can be used to scrape the excess sand and soil on the edge of the road during the forward movement of the flat trolley 1. At the same time, when encountering a curve, the servo motor 322 in the motor slot 321 opened at the bottom of the fixed hanging plate 32 is started to drive the turntable 323 to rotate clockwise by a certain angle, so that the right end of the forklift blade 33 at the bottom of the turntable 323 is tilted backward by a certain angle, so that the forklift blade 33 can adapt to different road conditions, and the scraped mud and sand can be directly discharged to the road slope. At the same time, the hydraulic cylinder 343 behind the limit box 342 on the rear side of the bottom plate 341 is started to drive its output When the sending end is retracted, the fixed connection between the connecting plate 344 and the sliding slope repair scraper 345 and the sliding of the sliding slope repair scraper 345 and the inner cavity of the limit box 342 can be used to make the sliding slope repair scraper 345 tilt and move down to the bottom of the slope, and then the hydraulic push rod 2 3241 in the translation adjustment box 324 is oiled to drive its output end to drive the connecting slider 332 to move to the left in the translation adjustment box 324, and the fixed connection between the connecting slider 332 and the top of the fixed hanging plate 331 can be used to drive the entire forklift blade 33 to drive the extended sliding slope repair scraper 345 to move to the left until it fits the sand on the road slope, thereby cooperating with the forward movement of the flat cart 1, and the sliding slope repair scraper 345 on the rear side of the forklift blade 33 can be used to trim the road slope, so as to achieve the goal of pushing the sand on the edge of the road and trimming the slope at the same time.
[0030] While the present invention has been generally described above, it is readily apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are intended to be within the scope of protection of the present invention.
