Description

Submerged plant harvesting device

Technical Field

The utility model relates to the technical field of the environment, concretely relates to benthophyte reaping apparatus.

Background

Submerged plants are large aquatic plants whose plant bodies are all located below the water layer and live in a nutritional and fixed manner. The submerged plant can absorb the nutrient substances such as nitrogen, phosphorus and the like in the water, and has the function of purifying the water quality. The submerged plants can also reduce the content of suspended silt in the water body and improve the transparency of the water body; controlling the growth of algae; provide habitat for aquatic organisms and the like, and play an important role in lake and river ecosystems.

However, submerged plants tend to grow in large quantities in water due to eutrophication of the water, etc. After the submerged plants die and decay, the nutritive salt accumulated in the body can be released, so that the effect of purifying the water quality can not be exerted, and the water body can be polluted. Therefore, submerged plants need to be harvested or salvaged periodically to reduce their biomass.

The general harvesting modes include manual harvesting, simple mechanical harvesting, large mechanical harvesting and the like. The manual harvesting means a harvesting mode that submerged plants are pulled out or pulled off from water by bare hands and transported to the shore. Simple harvesting with the apparatus is carried out with the apparatus such as a push broach, a sickle, a bamboo pole and the like. Both of these methods consume a lot of manpower and are inefficient. In addition, these methods have difficulty in controlling the harvest strength, often resulting in severe damage to the submerged plants.

The existing large-scale machinery reaps, so that the reaping efficiency is improved, and the roots of submerged plants are not easy to damage; however, because the lake banks are irregular, harvesting dead angles are easy to occur when large-scale machinery harvests, the depth is irregular, a lot of submerged plants are incompletely harvested, and the water body is easy to be polluted after the submerged plants are rotten.
