Description

Technical Field

[0001] The invention relates to the technical field of grassland net frames, and in particular to a net frame used for restoring the surface soil of degraded grasslands in mountainous desert grasslands. Background Art

[0002] The mountain desert grassland grassland net frame is a modern ecological protection facility designed to effectively improve and restore the ecological environment of mountainous areas and desert grasslands. It is made of high-strength, corrosion-resistant materials, has good toughness and pressure resistance, and can maintain a stable structure under extreme weather conditions. Through reasonable layout and design, the net frame can divide the grassland into several suitable areas, promote plant growth and reproduction, and provide a good foundation for the restoration of grassland ecology. At the same time, the net frame can effectively prevent overgrazing of livestock, reduce the risk of land degradation, and promote the protection of biodiversity. In addition, the construction and management of mountain desert grassland grassland net frames not only contributes to the construction of ecological civilization, but also provides local farmers and herdsmen with a more sustainable production model, and promotes the coordinated development of ecology and economy. Through scientific management and use, this facility will provide strong support for future grassland and ecological protection.

[0003] After searching, the invention patent with Chinese patent number CN108951598A discloses a mesh frame for restoration of topsoil of degraded grassland in mountain desert steppe, including separable fixed piles and filter assembly, a plurality of foldable brackets are arranged on the fixed piles to quickly and conveniently fix the fixed piles on the ground without hindering the storage and transportation of the fixed piles; the filter assembly includes a filter body and two connecting columns respectively arranged at both ends of the filter body, the filter body can be wound around the two connecting columns, so that the distance between the two connecting columns is adjustable, holes are opened on the connecting columns, and a connecting column locking mechanism is arranged inside the fixed pile to cooperate with the hole to lock the connecting column, so that regardless of whether the filter as a whole is wound around the connecting column, the fixed pile and the filter assembly can be firmly fixed. Compared with the prior art, the invention patent with Chinese patent number CN108951598A solves the problem that the base, fixing rod and protective net in the existing net frame structure are fixed as one, which can improve the overall strength and adapt to the continuous strong wind invasion. However, the terrain in the actual working areas such as mountains and deserts is relatively complex. Some areas do not have large flat sites, and the equipment is difficult to arrange. There are also some exposed stones or concave holes on the surface, which will also bring inconvenience to the installation of such overall equipment.

[0004] However, in the actual use of the above-mentioned device, there are many gravels on the surface in Xinjiang. These gravels will lift up the bottom of the base when installing the net frame base, thereby affecting the balance of the base. In addition, some grasslands are set at the junction of the foot of the mountain and the flat land, with a certain slope, and the fixed base structure is difficult to adjust according to the slope, and the use effect is not good. Therefore, a net frame for restoring the topsoil of degraded grasslands in mountain desert grasslands is proposed. Summary of the invention
