The working principle of the present invention is as follows: the concave-convex arc is used to tamp the curved surface, which greatly increases the tamping effect of the tamping mechanism on the bulk filling material, especially the tamping effect of the vertical connection to the top. The convex part in the middle of the concave-convex tamping curved panel can decompose the tamping force into horizontal direction and vertical direction. Compared with the conventional plane tamping mechanism, it can not only tamp the filling bulk in the horizontal direction, but also in the vertical direction. Vertical compaction to the roof is a key problem in solid filling. The upper and lower concave-convex arc-shaped surfaces corresponding to the convex surface in the middle of the concave-convex tamping surface are used to converge the scattered particles caused by the convex surface in the middle, and at the same time further enhance the tamping efficiency of the tamping mechanism in the horizontal and vertical directions. Scattered particles, enhance the effect of compaction. Therefore, compared with the planar filling and compacting mechanism, the concave-convex curved surface filling and compacting mechanism of the present invention can not only effectively solve the problem of filling body connecting to the top in solid filling, but also greatly improve the compacting efficiency.
