Shrimp and crab culturing facility

Abstract

The invention discloses a shrimp and crab culturing facility. The facility comprises a pond, wherein a water treatment device is arranged at one end of the pond; multiple water separation walls are arranged in the pond and divide the pond into multiple water flowing channels which constitute an aquaculture water channel; a feeding device is arranged in the water flowing channel in the middle of the pond; an ejection device capable of ejecting materials in a feeding plate out of a discharging seat is arranged on a floating platform; a scraping plate mechanism capable of collecting materials at the front end of the feeding plate to the rear side of the feeding plate is arranged on the ejection device; a positioning rod is arranged at the end, where the discharging seat is arranged, of the floating platform, and a sail mechanism which enables the floating platform to change the direction along with the wind direction and rotate relative to the positioning rod to adjust the feeding direction is arranged at the other end of the floating platform. The shrimp and crab culturing facility aims to overcome defects in the prior art, is simple in structure, can effectively guarantee the content of oxygen in water and a good water quality condition and has a good culturing effect, good bait dispersity during feeding and a wide feeding range.

Description

technical field [0001] The invention relates to a shrimp and crab breeding 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 the pond far away fro...

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
