Cycling freshwater outdoor pond aquaculture facility

Abstract

The invention discloses a circulating fresh water outdoor pond culture facility, which includes a pond, a water treatment device is arranged at one end of the pond, and a plurality of water body partition walls are arranged in the pond, and the water body partition walls divide the pond into a plurality of flowing water channels The breeding waterway is equipped with a feeding device in the water channel in the middle of the pond. The feeding device includes a floating platform. On the floating platform, there is an ejection device that can eject the material in the feeding tray out of the discharge seat. On the ejection device, there is a The scraper mechanism that can concentrate the material at the front end of the feeding pan to the rear side of the feeding pan has a limit hole in the middle of the floating platform, and a positioning rod is set in the limiting hole. One end of the positioning rod is plugged into the bottom of the pond. A rotary drive mechanism capable of driving the floating platform to rotate relative to the positioning rod is arranged. The object of the present invention is to provide a circulating freshwater outdoor pond culture facility with a simple structure, which can effectively ensure good oxygen content and water quality in the water body, good breeding effect, good bait dispersion during feeding, and a wide feeding range.

Description

technical field [0001] The invention relates to a circulating fresh water outdoor pond culture facility. Background technique [0002] Pond culture is one of the main forms of aquaculture. Since the 1970s in China, fish pond culture, shrimp and crab pond culture, and aquaculture fry pond cultivation have flourished successively in China. The aquaculture water body is about 10 billion cubic meters , Such a large scale of farming has made great contributions to the development of my country's aquatic economy. Existing aquaculture ponds are mainly rectangular in shape with a uniform water surface, and the inlet and outlet are arranged at one end of the pond or separately at both ends of the pond. Except for a very small number of aquaculture ponds that are equipped with water stirring and aeration machines, The vast majority of ponds only have obvious water flow channels near the inlet and outlet, and most of the water exchange rate in other places is very low. The corners of t...

Problems solved by technology

Existing aquaculture ponds are mainly rectangular in shape with uniform water surface, and the inlet and outlet are arranged at one end of the pond or separately at both ends of the pond. Except for a very small number of aquaculture ponds equipped with water-stirring and oxygen-increasing machines, The vast majority of ponds only have obvious water flow channels near the inlet and outlet, and most of the water exchange rate in other places is very low. The corners of the pond far away from the inlet and outlet often become dead corners, the water quality in the pond is not uniform, and the local area is often hypoxic conditions, the cultured organisms cannot obtain a suitable growth environment, diseases frequently occur, the production speed is slow, and even the breeding capacity decreases, and the production efficiency is low

[0003] In addition, in order to improve the efficiency of breeding work, feeding devices are generally used when feeding feed to the farming area. Due to design defects, the current feeding devices on the market have poor dispersion of bait when feeding, and fish and shrimp need to be concentrated. eat in a small area

it's bad for feeding
