Ecological floating bed for crab breeding

Abstract

The invention relates to the technical field of crab breeding, and discloses an ecological floating bed for crab breeding. The ecological floating bed comprises a breeding pond and a floating bed body, a storage cylinder is arranged above the floating bed body, the outer side wall of the storage cylinder is fixedly connected with a support frame, the lower end of the support frame is fixedly connected with the upper end of the floating bed body, and the lower end of the storage cylinder is fixedly connected with a discharge pipe; and an electromagnetic valve is fixedly arranged in the discharge pipe, a material uniformizing disc is arranged below the discharge pipe, the material uniformizing disc is arranged in a conical shape, the lower end of the material uniformizing disc is sequentially provided with an inclined section and a horizontal section from outside to inside, and the upper end of the floating bed body is fixedly connected with a supporting block. According to the ecological floating bed for crab breeding, automatic feeding can be conducted, uniform throwing can be conducted, it is avoided that feed is thrown together, and crab feeding is affected, the functionality ofthe ecological floating bed is improved, the labor amount of workers is reduced, meanwhile, the deformation resistance of the ecological floating bed can be improved, and the service life of the ecological floating bed is prolonged.

Description

technical field [0001] The invention relates to the technical field of crab cultivation, in particular to an ecological floating bed for crab cultivation. Background technique [0002] Crab is a common crustacean. Most species of crabs live in the sea or offshore areas, and some live in fresh water or on land. With the rapid development of crab breeding industry, scientific breeding is getting more and more attention. Among them Ecological floating bed is a commonly used technology. Aiming at eutrophic water quality, it uses the principle of ecological engineering to degrade the content of COD, nitrogen and phosphorus in the water. It uses aquatic plants as the main body, uses the principle of soilless cultivation technology, and uses polymer materials. etc. as the carrier and substrate, and the application of the symbiotic relationship between species can greatly improve the transparency of the water body, and at the same time the water quality indicators have also been eff...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an ecological floating bed for crab breeding, which has the advantages of automatic and uniform feeding, reduces the labor workload of workers, improves the convenience of use, prevents crabs from gathering and eating, and is beneficial to crab breeding. The ecological floating bed generally occupies a large area of ​​the water surface. When artificially feeding feed, it can only be fed on the four sides of the floating bed, causing crabs to pile up and eat, and the injury rate of crabs is greatly increased, and the food intake will also be reduced, which is not conducive to crab breeding , and the function of the ecological floating bed is relatively single, it cannot be automatically fed, and the market competitiveness is low
