Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of environment, in particular to a submerged plant harvesting and slitting device. BACKGROUND

[0002] Submerged plants are aquatic plants with all plant parts under water, which have the performance of purifying water quality, improving water transparency, reducing suspended sediment, absorbing nitrogen and phosphorus, etc. and are commonly used aquatic plants in current environmental management. However, due to eutrophication of water body and other reasons, submerged plants will grow a lot in water, and the release of solidified salt after the death and decay of submerged plants will cause the biological density of submerged plants to be too high to cause other species to be unable to survive, resulting in deterioration of the water environment. Therefore, it is necessary to regularly harvest and clean the submerged plants.

[0003] In the prior art, the harvesting methods of submerged plants include manual harvesting and mechanical harvesting. The efficiency of manual harvesting is low and is not suitable for large lakes and rivers. The efficiency of mechanical harvesting is higher and is the main direction of the development of submerged plants. The currently disclosed submerged plant mechanical harvesting device mainly cuts the submerged plants directly through a cutter and collects the cut submerged plants through a collecting device. For example, the harvesting and collecting device based on submerged plant cleaning disclosed in Publication No. CN216362619U cuts the submerged plants through a cutting device and then collects the cut plant bodies through a grass blocking net. For another example, the submerged plant harvesting device disclosed in Publication No. CN211580696U harvests the submerged plants through a U-shaped cutter and a roller conveyor. Since the submerged plants are usually filamentous or strip-shaped, it is difficult to completely collect the cut plant bodies after cutting the submerged plants directly with a cutter, which will cause a large amount of submerged plants to remain in the water body and easily cause slight water pollution.

The collected submerged plant body is in a vertical state at the head of the collection end and in a horizontal state at the tail of the collection end. When the collected submerged plant reaches the tail of the collection end, the harvesting knife at the tail of the collection end starts to cut the submerged plant. At the same time, the baffle on the harvesting knife blade pushes the cut submerged plant body between the first conveying belt and the soft rubber conveying belt.

The second conveying belt is provided with a special-shaped hook, which can form a hooking action on the submerged plant, transport the submerged plant body transported by the first conveying belt from the water to the water surface, and transport the submerged plant element to the third conveying belt. After the submerged plant is transported to the third conveying belt, the third conveying belt continues to transport the submerged plant to the slitting assembly. The slitting assembly adjusts the slitting cutter unit according to the harvested submerged plant, the plant species, and the cutting requirements. When a single slitting cutter unit is used, the rotation speed of the transmission gear can be adjusted to adjust the cutting length. When multiple slitting cutter units are used in combination, different cutting lengths can be cut at the same time. The cut submerged plant body is transported to the screening assembly again. The screen on the screening assembly can screen different lengths of submerged plant bodies and impurities to ensure the quality of the subsequent submerged plant product. The obtained submerged plant product can be directly applied to feed production.
