Description

Technical Field

[0001] The utility model belongs to the technical field of land-based circular pond aquaculture, and in particular relates to a shrimp shell collection and discharge device for land-based circular pond aquaculture of prawns. Background Art

[0002] Land-based circular pond aquaculture technology is an integrated aquaculture method that uses a variety of treatment methods such as filtration, oxidation, and disinfection to recirculate the water in the pond back into the aquaculture pond, thereby saving water, reducing wastewater discharge, and improving the benefits of aquaculture. Compared with the traditional pond aquaculture model, the land-based circular pond circulation technology has a higher aquaculture density and more stable water quality. It can reduce water consumption in a continuous cycle, improve aquaculture benefits, and reduce pollutant emissions, which helps promote the sustainable development of aquaculture. At the same time, land-based circular pond circulating water aquaculture can treat the aquaculture pond water through filtration, oxidation, disinfection and other technologies to keep the water quality stable, effectively reducing the risks of aquaculture. The land-based circular pond aquaculture technology can be used to recycle the heat energy in the aquaculture pond through energy-saving equipment such as heat pumps, thereby achieving energy conservation and emission reduction. Therefore, the land-based circular pond aquaculture technology has a higher aquaculture density, more stable water quality and lower costs, and is a breeding technology with excellent prospects.

[0003] During the process of farming shrimp in land-based circular ponds, the shrimp will shed their shells and sink to the bottom of the pond as they grow. Therefore, the shrimp shells at the bottom of the circular pond need to be cleaned regularly to avoid the breeding of viruses and bacteria, which will affect the growth environment of healthy live shrimp.

[0004] The traditional way of collecting shrimp shells is to manually go down into the circular pond and use a scoop net to collect and discharge the shrimp shells. This method is not only time-consuming and labor-intensive, but also has low work efficiency and certain safety hazards.

[0005] In the prior art, there are a variety of shrimp shell removal devices, but they generally require the support of electricity and power equipment, have complex structures, and are costly. In addition, when removing the shrimp shells, live shrimps at the bottom of the round pond will be removed, affecting the breeding efficiency. Utility Model Content
