Description

Technical Field

[0001] The utility model relates to a wetland weeding device in the technical field of water quality improvement, and particularly relates to a vallisneria grass mowing device. Background Art

[0002] In recent years, due to the continuous decline of the overall quality of water resources, the water quality of lakes and scenic spots has been severely eutrophicated, mostly class V water or even inferior class V water, and the use function and self-repair function of water bodies have been partially or completely lost. Water ecological restoration refers to the restoration and treatment of water quality improvement, soil and water conservation, animal and plant habitat, and greening and beautification of lakes, rivers, and wetlands to restore and protect the aquatic ecological environment.

[0003] Vallisneria grass is a submerged herbaceous plant of the genus Vallisneria in the family Hydrocharitaceae. It is a common dominant species in water ecological restoration and is widely used in water quality improvement projects of wetland water bodies. It can absorb nutrients such as nitrogen and phosphorus in water, helping to control water eutrophication. In addition, since it is one of the native plants in China, it has strong adaptability and stress resistance, so it has important application value in water ecological restoration.

[0004] However, the planting of vallisneria grass itself also has certain limitations. First of all, the growth rate of vallisneria grass in nature is relatively fast. If not controlled, it will quickly cover the water surface, resulting in the formation of a grass mat on the water surface, which not only affects the beauty of the water body but also may hinder the natural flow of the water body and reduce the self-purification ability of the water body. In addition, vallisneria grass will bloom from August to October, and the pollen floating on the water surface and dispersed into the air will have an adverse impact on the surrounding environment and human health. For the above reasons, vallisneria grass needs to be cut regularly during ecological planting to maintain the landscape and water purification function. However, traditional vallisneria grass mowing methods mostly rely on manual labor, which is not only inefficient but also most of the existing mowing equipment is not convenient for telescoping. It is necessary for workers to hold a mowing machine and go down into the water area where vallisneria grass is planted to harvest vallisneria grass. This not only has a large labor intensity, is time-consuming and laborious, but also easily poses a risk of scratching the hands of workers underwater. Content of the Utility Model
