Description

Technical Field

[0001] The invention relates to the technical field of desert control, and in particular to a device for laying desert grass grids. Background Art

[0002] At present, the prevention and control measures for land desertification are mainly divided into three types: biological control measures, enclosure measures and engineering control measures. However, the real desert is not a static sand land. There are some large and mobile sand dunes on the surface of the desert. In the upwind area, the sand dunes move and spread under the operation of wind, eroding green space. Therefore, engineering control measures are needed to prevent the movement of sand dunes. The most typical and effective engineering measure is to set up sand barriers to fix sand dunes. Among the many wind-proof and sand-fixing measures, setting up grass grid sand barriers is one of the most basic methods. It increases the surface roughness and slows down the wind speed through physical means to prevent the flow and expansion of sand dunes. At the same time, it plays a certain role in soil improvement. However, the manual laying of grass grids under the harsh conditions of deserts and sandy land is labor-intensive, inefficient, and costly. In addition, it is difficult to uniformly control the laying depth of grass grids, and shallowly buried grass grids will be blown away from the sand by the wind.

[0003] In the prior art, most grass grid paving machines can only lay two parallel grass barriers. It is necessary to wait until the horizontal paving is completed before the vertical paving can be carried out to complete the laying of the grid-shaped grass barriers. The laying efficiency is low, the use is limited and only one-way laying can be achieved. When the grass is exhausted during the paving process, it is necessary to frequently stop the machine to manually install a new grass roll, and there is still a distance between the feed port and the grass pressing wheel. After the grass roll is replaced, the grass roll head needs to be manually pulled out to connect to the grass pressing wheel on the ground, which is very inconvenient. Summary of the invention
