Culture pond aquatic plant cutting device

Abstract

The invention discloses a culture pond aquatic cutting device. The device comprises a fixing seat fixed on a hull; a support frame arranged on the fixing seat; a servo motor arranged on the support frame, and a connector moving relative to a lead screw, wherein an output end of the servo motor is connected with the lead screw, and a cutter device for cutting the aquatic plant under the water surface is arranged at a lower end of the connector. The cutting device disclosed the invention is simple in structure, the motor drives the lead screw to move, the lead screw coverts curvilinear movementinto linear movement, thereby driving the cutter device to move up and down. The device can save the labor force, improve the aquatic plant cutting speed and cutting quality. The device further can integrate the water depth sensing and collection and like functions, and is suitable for performing the aquatic plant cutting in the shrimp-crab culture pond at the Jiangsu area by loading on the ship,and the shrimp-crab pond culture environment is optimized, the feed labor condition is optimized, the feeding cost is reduced, and the cutting device has important practical significance for improvingthe yield of the pond-cultured shrimp-crab.

Description

technical field [0001] The invention relates to a harvesting device for aquatic plants in a breeding pond, which belongs to the technical field of agricultural machinery. Background technique [0002] Aquatic grass conservation is a key link in shrimp and crab farming. In freshwater river crab breeding areas in Jiangsu, the depth of the breeding pond is generally 0.5m-1.0m, and the pond area is generally 10-50 mu to 50-60 mu. The important ways to increase aquatic products mainly include further expanding the aquaculture area and increasing the output per unit area. River crab breeding needs to plant aquatic plants such as Elodea and water leek in the pond, which are rich in nutrients and can supplement the deficiency of multivitamins in grains and other feeds. Feeding shrimp and crabs can save about 30% of concentrated feed, and feeding grass-fed Sexual fish save about 50% of concentrate feed. Elodea planted in shrimp and crab ponds can purify water quality and prevent e...

Problems solved by technology

[0003] Purpose of the invention: In the prior art, most of the aquatic plants are harvested manually. The manual harvesting of aquatic plants is often very inefficient, labor-intensive, and working conditions are harsh, especially in large-scale breeding environments because the speed of harvesting cannot keep up. The speed of growth of aquatic plants and the unsatisfactory harvesting effect, etc., the present invention provides a harvesting device for aquatic plants in breeding ponds suitable for river crab breeding waters
