TECHNICAL FIELD

[0001] The utility model relates to mine afforesting technical field, concretely relates to a kind of flat device after covering soil for mine dump. BACKGROUND

[0002] Mine dump, also known as waste rock field, refers to the place where mining waste is concentratedly discharged. The mining waste of mine dump generally includes humus topsoil, weathered rock soil, hard rock and mixed rock soil, and sometimes includes surface ore and lean ore that can be recovered. The surface layer of dump is mainly composed of waste ore slag and stone blocks after washing and stacking, and the particle size is very uneven. Therefore, it is difficult to naturally weather and crush in the short term, and it is loose and has large voids, so the water holding capacity is poor, and the soil nutrients are also poor.

[0003] Ecological restoration and vegetation reconstruction of mine dump have always been the focus and difficulty of mine reclamation. Since the surface of dump is not covered with topsoil, direct planting of plants cannot survive. Considering the ecology and safety of dump, it is appropriate to reclaim the dump as grassland. During the reclamation process, it is necessary to cover soil first, and then to level the site after covering soil.

[0004] In the prior art, mechanical leveling is generally used. However, the places corresponding to the tracks or wheels of the machine are usually not directly leveled, and manual secondary leveling is required, which not only consumes manpower, but also reduces the efficiency of site leveling, affecting the progress of the project.
