[0036] Preferably, in the embodiment, the scraper 1 is a three-section assembled structure, and adjacent two scraper 1 units are detachably connected by bolts, which can be assembled and disassembled, and is convenient to carry after disassembly.

[0037] The working principle of the land leveling device is as follows:

[0038] When the land is developed and utilized, the truss 13 of the land leveling device is connected to the tractor, and the tractor drags the device to move, which is the conventional use of the existing land leveling scraper;

[0039] In the initial state, the bottom surface of scraper 1 is in contact with the ground. Since the weight of roller 8 and square slide bar 7 is greater than the weight of baffle 2 and I-shaped connecting rod 4, roller 8 is supported on the ground and baffle 2 is suspended in the air. As the tractor drags scraper 1 to level the ground, roller 8 rolls on the ground.

[0040] When one or more of the rollers 8 encounter a small mound of soil (the mound is limited to having a height less than half the height of the scraper 1), such as Figure 7 As shown, the roller 8 is pushed upward by the small mound of soil. When the square sliding rod 7 moves upward, it pushes the right end of the V-shaped connecting rod 5 to rotate upward, causing the left end of the V-shaped connecting rod 5 to rotate downward. The V-shaped connecting rod 5 pushes the I-shaped connecting rod 4 downward, thereby pushing the baffle 2 to move downward on the right side wall of the scraper 1. This causes the baffle 2 to cover the groove 1.1, reducing the opening size of the groove 1.1. When the scraper 1 reaches the small mound of soil, since the groove 1.1 on the left side of the roller 8 is partially or completely covered by the baffle 2, the soil in the small mound is diverted in the forward and backward direction on the right side of the scraper 1, reducing the amount of soil passing through the groove 1.1 on the left side of the small mound. This helps the scraper to scrape the excess soil in the small mound to the surrounding area.

[0041] When one or more rollers 8 encounter a depression (the depression is limited to a depth less than half the height of the scraper 1), the rollers 8 fall into the depression under gravity. The rollers 8 and the square slide bar 7 move downwards. When the square slide bar 7 moves downwards, it drives the right end of the V-shaped connecting rod 5 to rotate downwards, causing the left end of the V-shaped connecting rod 5 to rotate upwards. The V-shaped connecting rod 5 pushes the I-shaped connecting rod 4 upwards, thereby pushing the baffle 2 to move upwards on the right side wall of the scraper 1 to reduce the obstruction of the groove 1.1 and increase the opening size of the groove 1.1. When the scraper 1 reaches the small mound, because the groove 1.1 on the left side of the roller 8 is open, the soil around the depression gathers towards the depression on the right side of the scraper 1. More soil passes through the groove 1.1 on the left side of the depression. After the scraper 1 passes through the depression, more soil can fill the depression.

[0042] The aforementioned land leveling device can more efficiently divert or collect soil when leveling land. By adjusting the opening size of each groove 1.1, the amount of soil passing through each groove 1.1 can be controlled. The scraper 1 can scrape the excess soil from small mounds to the surroundings more quickly, or scrape the soil around the pits into the pits for backfilling more quickly. This helps reduce the number of times the tractor has to go back and forth, saves time, and improves land leveling efficiency.

[0043] Finally, it should be noted that: the above embodiments are used to illustrate the technical solutions of the present application, rather than limiting them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should be covered in the scope of the claims and the specification of the present application.
