[0002] Land leveling refers to the transformation of the land surface through demolition and earthwork, the removal of buildings, structures and obvious height differences in different parts of the land to meet the requirements of subsequent construction. Land leveling in land consolidation refers to the construction of fields and soil fertility conservation measures to meet the needs of farmland cultivation, irrigation and drainage.

[0003] For example, CN211745160U discloses a land leveling device, which can expand the area of ​​the ground leveling through the design of the clamping block, the clamping rod and the scraper, so that more ground can be leveled at the same time, effectively improving the efficiency of ground leveling, and the scraper bottom adopts a V-shaped design, so that the bottom can easily break large pieces of soil, and through the design of the roller, the handle and the movable plate, the user can easily push the device to move, and the land leveling can be completed during the movement, without consuming more physical strength, which reduces the labor intensity for the user and improves the practicality of the device. However, during use, the device needs to be manually operated to break the soil blocks, which requires more labor and physical strength to be wasted during work, and although the scraper can break the soil blocks, the size of the broken soil blocks is limited, and the soil blocks cannot be fully broken, so it needs to be optimized and improved.

The positioning bracket 2 is L-shaped, and a diagonal support plate is provided on one side of the positioning bracket 2. The pressure spring 14 and the pressure spring 2 15 can support the flat plate 13 and the positioning bracket 2, so that the positioning bracket 2 can move inside the connecting frame 1 to adjust the height, thereby allowing the protective cover 3 to move up and down in height following the slope of the land.

[0025] Specifically, the servo motors 4 are provided with four and are evenly arranged inside the protective cover 3. The cutting knives 7 are distributed in a circle around the bottom of the disc 6. One side of the protective cover 3 is in an arc shape, and guide wheels 16 are provided on both sides below the protective cover 3. The cutting knives 7 can cut and crush the soil blocks again to reduce the volume of the soil blocks. The protective cover 3 can protect the outside of the cutting knives 7 to prevent accidental injury by the cutting knives 7 and reduce the scattering of soil blocks around when the cutting knives 7 crush the soil blocks.

[0026] Example 2: Please refer to Figure 2 The difference between this embodiment and embodiment 1 is that: a pressure spring 3 17 is provided inside the sleeve 10, the top end of the pressure spring 3 17 is in contact with the fixing rod 9, the fixing rod 9 is slidably connected inside the sleeve 10, the number of the pressure rollers 12 is three and the heights are arranged in sequence from top to bottom, and the pressure rollers 12 can press on the soil to flatten the soil when the protective cover 3 moves, thereby keeping the soil flat.

[0027] Working principle of the utility model: when in use, the connecting frame 1 can be installed on agricultural machinery such as a rotary tiller. After the rotary tiller has initially turned over and broken the land, the servo motor 4 drives the cutting knife 7 to rotate to break the soil blocks again, thereby reducing the volume of the soil blocks, and the positioning bracket 2 can move up and down inside the connecting frame 1. When encountering uneven ground, the positioning bracket 2 and the protective cover 3 can automatically adjust the height according to the pressure with the ground to prevent the soil from entering the protective cover 3 and accumulating inside the protective cover 3 in large quantities due to the inability to adjust the height position of the protective cover 3. A plurality of cutting knives 7 are arranged inside the protective cover 3. When the cutting knife 7 rotates, the soil blocks can be cut and broken for multiple times, thereby effectively reducing the volume of the soil blocks, which is beneficial to leveling the soil. When the pressing roller 12 passes through the crushed soil, the soil can be flattened to keep the land flat.
