In use, when a large pile of earth is encountered, a large directional force is required to be applied to the adjusting frame 43. When the weight of the adjustment bracket 43 is small, a shaking occurs in a large counter-force, and even the structure is unstable. By providing the weight box 433 to increase the weight of the alignment bracket 43, the alignment bracket 43 can provide a large impact force when it is heavy, thereby pushing the soil pile flat. Even if a large directional force is applied, the adjusting bracket 43 has a strong bearing capacity when it is heavy, and can bear a large directional impact force, thereby ensuring a stable structure. The plurality of weight boxes 433 are uniformly distributed along the axial direction of the frame 432, so that the weight of the frame 432 is uniformly distributed in the axial direction, and the integral stability of the structure of the frame 432 in the axial direction is ensured.
The weight of weight box 433 is adjusted by increasing or decreasing the number of first weights 4335 as required by the actual operation. After the number of the first weights 4335 in one weight box 433 is adjusted, the lower end of the first bolt 4332 is rotated to tightly abut against the top end of the first weight 4335 to be fixed. In the use, when the oscillation appears and produces vertical ascending effort under the exogenic action, the vertical effort that first balancing weight 4335 oscillation produced transmits splint 4333, and splint 4333 extrudes third spring 4331, and third spring 4331 receives the extrusion and produces deformation in order to absorb the extrusion force, plays the buffering guard action, avoids the striking to lead to the structure to damage.

The strike 63 comprises a housing 631, the housing 631 being triangular prism-shaped. The second weight block 632 is rectangular frustum pyramid shaped, and the second weight block 632 is disposed in the casing 631 along the height direction of the casing 631. The second weights 632 are arranged along the width direction of the housing 631 to form a group. The plurality of sets of second weights 632 are arranged along the length direction of the housing 631.
In use, the second counterweight 632 is fixed within the housing 631 as desired. When the scraping member 63 is required to provide a large scraping force, the second balance weight blocks 632 are fixed in the casing 631 by bolts, and the scraping member 63 has a large weight and provides a large downward pressing force. The scraping member 63 can scrape the ground surface when it is scraped off the ground surface. When the land is relatively flat and a large scraping force is not needed, a small amount of the second balancing weight 632 is fixed in the shell 631 by bolts, and the scraping piece 63 has a small weight and provides a small downward extrusion force.
The rolling element 64 includes a rolling cylinder 641, and the rolling cylinder 641 is cylindrical. The support block 643 is trapezoidal.
