The motor grader of the present invention will be described in detail with reference to fig. 1 to 13.

The grader of this embodiment includes mounting bracket 2, still includes fixing base 8. The mounting frame 2 is annular. The fixing seat 8 is fixed at the edge of the lower side surface of the mounting frame 2 through bolts. The traction frame 1 is fixed on the upper side of the mounting frame 2 by bolts. The fixed seat 8 limits the position of the rotating shaft 3. The compacting members 4 are pivotally connected to the rotating shaft 3, and a plurality of compacting members 4 are distributed along the axial direction of the rotating shaft 3. The number of the compacts 4 in this embodiment is 8. The adjusting frame 6 is screwed on the lower side of the mounting frame 2 by screw threads. The scraper 5 is screwed on the adjusting frame 6 by screw threads. The scraping frame 7 is screwed on the lower side of the adjusting frame 6 by screw threads. In the radial direction of the mounting frame 2, the compacting member 4, the scraping plate 5 and the scraping frame 7 are arranged in sequence.

The mounting frame 8 comprises a V-shaped fixing frame 82, a V-shaped groove is concavely arranged in the fixing frame 82, and the mounting frame further comprises a base 83. The base 83 slides on the bottom of the V-shaped groove. The first screw 84 is screwed to the bottom of the fixing frame 82, and one end of the first screw 84 extending into the V-shaped groove is screwed to the base 83.

The spring 85 is sleeved on the first screw 84, and the spring 85 is compressed between the fixing frame 82 and the base 83. The first spring plate 81 is fixed to the upper portion of the V-shaped groove by bolts. The first spring plate 81 is arc-shaped, the plurality of first spring plates 81 are stacked together, and the stacked plurality of first spring plates 81 are placed on the upper portion of the inner cavity of the V-shaped groove. The base 83 includes a seat body 832, and a semicircular pressing groove 831 is formed in an upper portion of the seat body 832 in a concave manner. The seat body 832 is shaped as a frustum with the crush slots 831 at the larger cross-sectional end of the frustum. When the rotating shaft bearing is used, the rotating shaft 3 is placed between the base 83 and the first spring plate 81, a space is enclosed by the base 83 and the first spring plate 81 and is used for bearing the rotating shaft 3, the first screw 84 is rotated to drive the base 83, and the base 83 is supported on the lower side of the rotating shaft 3. The first spring plate 81 covers the upper side of the rotating shaft 3, the spring 85 presses against the lower side of the base 83, and the spring 85 pushes the base 83 to realize position limitation on the rotating shaft 3. The spring 85 presses the base 83, so that the base 83 is prevented from shaking and shifting.

When the first screw 84 is rotated towards the fixed frame 82, the base 83 is driven to slide towards the inner cavity of the fixed frame 82, the base 83 moves to push the rotating shaft 3 to move, the rotating shaft 3 rises and simultaneously drives the compacting member 4 to rise, and the height of the compacting member 4 from the ground is increased. The compaction force on the ground decreases when the distance between the compacting member 4 and the ground increases. When the first screw 84 descends and drives the base 83 to descend, the distance from the rotating shaft 3 to the ground is reduced, the rotating shaft 3 is close to the ground, and the pressure of the compaction part 4 on the ground is increased along with the descending of the compaction part 4.

The positions of the scraping plate 5, the adjusting frame 6 and the scraping frame 7 are adjusted according to the ground condition needing to be scraped, so that the scraping requirements on various uneven ground surfaces are met.

When the cross rod 64 extends downwards, the cross rod 64 is driven to move downwards, and simultaneously, the lower edge of the scraper 5 is close to the ground along with the rotation of the scraper 5, so that the lower edge can be more effectively contacted with the ground and can scrape soil piles when scraping soil. When the cross bar 64 rotates upwards, the cross bar 64 is driven to move upwards, and simultaneously the scraper 5 is driven to rotate, the distance between the lower edge of the scraper 5 and the ground is increased, and less soil is scraped when the scraper 5 moves.

A fourth screw 66 is screwed to the middle of the cross bar 64, and the fourth screw 66 is used to connect the cross bar 64 and the screed plate 7 together. The fourth screw 66 is rotated to drive the scraping frame 7, the inclination angle and the direction of the scraping frame 7 are changed, and the ground scraping requirements of the scraping frame 7 under various conditions are met.

When the fourth screw 66 extends outwards, the distance between the bottom of the leveling frame 7 and the ground is reduced along with the downward movement of the leveling frame 7, so that the leveling frame 7 can be in closer contact with the ground, and deeper soil layers can be leveled by the leveling frame 7.

When the fourth screw 66 rotates upwards, the distance between the bottom of the screed frame 7 and the ground is reduced along with the upward movement of the screed frame 7, so that the screed frame 7 is convenient to be far away from the ground, and the screed frame 7 can only scrape a relatively shallow soil layer.

When the scraping blade 53 is far away from the ground, it can only scrape the soil higher than the ground. Conversely, when the third screw 63 rotates in the opposite direction, the main plate 51 is driven to rotate in the opposite direction, and the scraper 53 is closer to the ground, so that the scraper 53 can scrape more soil.

When the third screw 63 is screwed into the cross rod 64, the scraper 5 is driven to tilt integrally, the lower edge of the leveling knife 53 tilts, the height of the lower edge of the leveling knife 53 from the ground is increased, and the scraper is convenient for scraping higher soil piles.
